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
