Advantages and importance of grounding enhanching material?
What is grounding enhanching material The grounding enhanching material is an excellent conductive material that can help you solve your toughest grounding challenges. This material works well in poorly conductive locations such as rocky ground, hilltops and sandy soil. The grounding enhanching material can help to significantly reduce ground resistance and impedance measurements. In addition, grounding enhanching material can reduce the size of the grounding system where conventional methods cannot be used satisfactorily. Next, Sichuan Sunlight intelligent electric equipment Co., Ltd will introduce the advantages of grounding enhanching material and the importance of grounding enhanching material. Advantages of grounding enhanching material The grounding enhanching material remains conductive after installation without the need for maintenance, regular filling or reliance on water sources. Once the system is set up, maintains constant resistance over its life cycle, can be used in all soil conditions, even during dry periods, does not require regular fill treatment or placement, does not require continuous water supply to maintain conductivity, 3 days Fully fixed, fully cured within 28 days, will not dissolve, decompose or leach over time, conductors are difficult to remove from concrete, reducing vandalism and theft. The above is the advantages of grounding enhanching material. grounding enhanching material The importance of grounding enhanching material The main reason for many grounding device expansion accidents inside and outside the power grid is that the thermal capacity of the grounding device is seriously insufficient, some are caused by corrosion, and some are caused by improper design and construction; condition. Due to the pitting corrosion of hot-dip galvanized steel, and the pitting corrosion rate is several times higher than the annual average corrosion value, the ground grid will be corroded and broken in 7 to 8 years. Although sampling and excavation inspection can be performed, due to the large ground network and the large number of down-conductors, it is difficult to ensure timely inspection. Multiple grounding device accidents inside and outside the network also show that the galvanized steel grounding device is unreliable. Strengthen anti-corrosion measures In the method of hot-dip galvanized steel plus anti-corrosion nano-conductive coating, the corrosion resistance is obviously better than that of pure hot-dip galvanized steel grounding material. Nanomaterials and film-forming materials are almost the same order of magnitude in particle size. They are easy to penetrate each other, and there is no obvious interface with each other. A strong film is formed on the surface of the dip-coated zinc steel, and the external electrolyte solution will not be able to penetrate into the coating. On the surface of the zinc layer inside the layer, the service life of the grounding enhanching material after dipping zinc is greatly extended, which enhances the electrical conductivity, corrosion resistance, impact resistance, and thermal stability of the grounding enhanching material.

Composition and structure of grounding device?
Composition of grounding device The grounding device consists of a grounding body and a grounding wire. The metal conductor that is buried in the ground and directly in contact with the ground is called the grounding body, and the metal conductor that connects the necessary grounding part of the electrical device with the grounding body is called the grounding wire. for the grounding grid. The grounding body is a metal body buried in the soil, such as steel pipe, angle steel, flat steel, etc., with a length of about 2.5 meters. The grounding body can be buried horizontally or vertically. When burying horizontally, flat steel is generally used to make the grounding body, and the burial depth should not be less than 0.6 meters. When buried vertically, steel pipes and angle steels with a wall thickness of about 3.5 mm or more are generally used. Weld the flat steel on the grounding body as the lead-out conductor, and weld the bolt on the lead-out conductor to connect with the grounding wire. The ground wire generally adopts insulated copper wire and bare copper wire. The minimum cross-sectional area of the ground wire is 1.5 mm2 for insulated copper wire and 4 mm2 for bare copper wire. The above is the composition of the grounding device. grounding device. Grounding device structure The grounding device can provide simple, effective, and economical protection for the bearing to prevent bearing damage caused by working current or system fault current and lightning current passing through the bearing. Its working principle is: that the grounding wire transmits the current on the car body directly to the axle through the grounding device, and then forms a grounding loop through the wheel and the rail. At present, the more common axle end grounding device structures on subways, passenger cars, and EMU vehicles are: the grounding body provides a conducting circuit for the bearing current and realizes the insulation from the axle box; the axle box cover realizes the installation of the grounding body and the axle box; friction The disk cooperates with the carbon brush located on the grounding body to provide a reliable conduction circuit for the bearing current and realize low wear; the bearing pressure plate realizes the bearing positioning and friction disk installation. The axle box cover for subway and bus grounding devices has a metal labyrinth structure to achieve bearing sealing. The CRH1 EMU does not have a labyrinth structure on the axle box cover to achieve bearing sealing but relies on the good sealing performance of the bearing itself. The contact points of the carbon brushes of the above structures are close to the center of rotation and have the advantages of low linear speed and low wear. The above is the grounding device structure. Excellent grounding device supplier From the above introduction, we can understand the composition of grounding device and grounding device structure.

Classification, basic concepts and installation of grounding devices?
Grounding device is also called grounding integration device: a device that forms an electrical connection between electrical equipment or other objects and the ground. (Building Electrical Construction Technology). The grounding device consists of a grounding electrode (plate), a grounding busbar (indoor and outdoor), a grounding down-conductor (grounding jumper), and a frame grounding. It is used to realize the purpose of connecting the electrical system to the earth. The metal object that is in direct contact with the ground for electrical connection is the ground electrode. It can be an artificial ground electrode or a natural ground electrode. This grounding electrode can be assigned some electrical function, such as being used as system grounding, protective grounding or signal grounding. The grounding busbar is the reference potential point of the electrical installation of the building, through which the part that needs to be grounded in the electrical installation is connected to the grounding electrode. It also serves another function, that is, by interconnecting the equipotential bonding lines in the electrical installation, the overall equipotential bonding between the large conductive parts of a building is realized. The connection line between the grounding electrode and the grounding busbar is called the grounding electrode lead. Safety isolating transformer safety isolating transformer. Transformers that supply tools, other equipment and distribution circuits with safe extra-low voltage. Its input winding and output winding are electrically isolated by at least the equivalent of double insulation or reinforced insulation. Next, an excellent grounding device manufacturer, Sichuan Sunlight intelligent electric equipment Co., Ltd, will introduce the classification of grounding devices, basic concept of grounding device resistance and installation of grounding device. Classification of grounding devices The grounding device is composed of a grounding body (round steel, angle steel, flat steel, steel pipe, etc.) buried in the soil and a grounding wire for connection. According to the purpose of grounding, the grounding of electrical equipment can be divided into: working grounding, lightning protection grounding, protective grounding, and instrument control grounding. Working grounding: It is the grounding required to ensure the normal operation of the power system. For example, the neutral point of the transformer in the neutral point direct grounding system is grounded, and its function is to stabilize the potential of the power grid to the ground, thereby reducing the insulation to the ground. Lightning protection grounding: It is the grounding set for the needs of lightning protection. For example, the grounding of lightning rods (wires) (now called lightning rods, wires, strips) and arresters is to make the lightning current smoothly lead to the ground, so as to reduce the lightning overvoltage, so it is also called overvoltage protection grounding. Protection grounding device: also known as a safety grounding device, it is a grounding device set up for personal safety, that is, the electrical equipment shell (including the cable sheath) must be grounded to prevent the shell from being charged and endangering personal safety. Instrument control grounding device: the thermal control system, data acquisition system, computer monitoring system, transistor or microcomputer type relay protection system, and telecontrol communication system of the power plant, etc., are set up to stabilize the potential and prevent interference. Also known as an electronic system grounding device. The above is the classification of grounding devices. basic concept of grounding device resistance The resistance of the grounding device refers to the resistance encountered when the current passes through the grounding body into the earth and spreads around. The earth has a certain resistivity, and if there is current flowing through it, the earth has different potentials everywhere. After the current is injected into the ground through the grounding body, it spreads around in the form of a current field. 15~20m away), the resistance per unit diffusion distance and the current density in the ground are close to zero, and the potential here is zero. The curve U=f(r) in the figure represents the potential distribution on the ground surface (r represents the distance from the lightning current injection point). The above is the basic concept of grounding device resistance. Installation of grounding device
