What are the advantage of an oil breaker transformer?
I'm not aware of any device called an 'oil breaker transformer'.However, an oil circuit breaker or, more correctly, an 'oil-filled circuit breaker' is one of several types of circuit breaker used in high-voltage systems. The oil has two functions: (1) it is a far better insulator than air, enabling the circuit breaker to be far more compact (reducing its 'footprint'), and (2) the oil is used to extinguish the arc when the circuit breaker trips under fault conditions -a jet of oil removes ionised contaminants from the arc path, lengthens and 'snaps' the arc, and cools the arc.
How works oil circuit breakers?
A circuit breaker is a safety device that is put in an electrical circuit. When something fails, or shorts out, the circuit breaker "senses" the excessive current and automatically opens (or breaks) the circuit. They are used in homes, as well as some electrical devices. They are different than a fuse in that a circuit breaker can be reset. A fuse on the other hand, has to be replaced once it opens up. I hope this helps you. for more info, here is a web page about circuit breakers: <a href="http://www.wisegeek.com/what-is-a-circuit-breaker.htm">Ciruit breakers</a>
How much power can an oil circuit breaker withstand?
16kv
What is oil circuit breaker?
An oil circuit breaker is a breaker that is immersed in a tank of insulating oil. The tank has two electrical bushings through the tank to allow the supply and load to be connected to the breaker. These breakers can be opened under a heavy amperage load. The insulating oil is used to extinguish the arc that is produced when opening a switch under load.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.
What is the difference between Air circuit breaker and Vacuum circuiut breaker?
"Air" and "Vacuum" describe how the breaker extinguishes the arcing current. An Air breaker opens far enough that the dielectric strenght of air is enough to extinguish the arc. A vacuum breaker's contacts are in a vacuum. Oil breakers use oil. SF6 breakers use SF6 gas to extinguish the arc.
What is function of vcb?
VCB is Vacuum Circuit Breaker. It is one of the type of Circuit breaker. In VCB arching chamber is vacuum instead of oil or such arc quenching media. Its function is to break the circuit automatically in case of fault or to isolate the circuit under normal situation also.
What are the three main types of high voltage switching gear met with in industrial installations?
High voltage switch gear operates in the voltage range of 36 kV and above. Minimum oil circuit breaker, air blast circuit breaker and SF6 (Sulphur hexafluoride) circuit breaker are the three mostly used disconnects for high voltage switchgear.
What is the difference between oil and an air circuit breaker. please could you answer with detail as i am confused?
Arc developed during closing/opening operation is extinguished by air in ACB and by oil in OCB
What is an example of a parallel series circuit in your home?
Two receptacles on a branch circuit, each in parallel, both in series with the circuit breaker. The blower motor, ignition transformer, and oil solenoid on an oil burner, each in parallel, all in series with the acquastat (water temperature control switch).
Which oil use in circuit breakers?
Standard residenetila and some smaller industrial type breaker don;t use any oil in them,,,they use a silicon grease as a lubricant and contact protectant.
