The High Voltage and Low Voltage are Inseparable from "Circuit breaker"

 

Usage and function of the air switch and circuit breakers are similar! Only general open space in the load of the occasion, the circuit breaker is generally used in relatively large load point occasions! Depending on the arc media, circuit breakers, including air circuit breaker (commonly known as air switch), vacuum circuit breakers, SF6 circuit breakers, oil circuit breaker. Civil electrical design voltage 220 to 380V circuit breaker medium is air, it said on air switch or circuit breaker. However, for the power system, it is necessary to treat specific identification.

 

The circuit breaker is generally divided into high-voltage circuit breakers and low voltage circuit breakers, under normal circumstances, we will be more than 3kV referred to as high-voltage electrical appliances. The low-voltage circuit breaker has said automatic switch it from the control circuit, in addition to, but also has a certain degree of protection features such as over load, short circuit, under-voltage and leakage protection. Its scope is quite extensive, almost everywhere in our daily lives, and our lives become safe leaving because it's there. The high voltage circuit breaker that we do not often contact electrical appliances, in control, the high voltage circuit in one of the electrical components in the high voltage circuit. Quick discoect the circuit breaker is used to coect or discoect the circuit during normal operation, the fault condition in the role of the relay apparatus, special circumstances (such as automatic reclosing to the fault line) reliably coected to the short-circuit current. Dedicated electrical high voltage circuit breaker is tued on or off the high voltage circuit under normal or fault conditions.
