Advantages of Circuit Breaker in Air Insulated Switchgear
Powerful protection function: Circuit breaker can automatically cut off the circuit when the circuit is overloaded, short-circuited, undervoltage and other faults occur, effectively protecting electrical equipment and lines from damage, preventing accidents from expanding, and ensuring the safety of personnel and equipment
Reusable: Unlike fuses, circuit breaker can be manually or automatically reset after actuation to resume normal operation. It does not need to be replaced every time it blows like a fuse, reducing the cost of use and maintenance workload
High breaking capacity: Circuit breaker has a high breaking capacity and can safely cut off large currents in a short time, extinguish arcs, ensure reliable circuit disconnection, and is suitable for circuits of various voltage levels and current sizes
Adjustable action value: The action current and action time of many circuit breakers can be adjusted according to actual needs to meet the protection requirements of different circuits and equipment, improving the accuracy and reliability of protection
Easy to operate: Circuit breaker the operation of the circuit breaker is relatively simple. Usually, only a manual operating handle or an electric control device is required to achieve closing and opening operations, which is convenient for daily maintenance and management.
Specification of Circuit Breaker in Air Insulated Switchgear
Application of Circuit Breaker in Air Insulated Switchgear
They are designed to safely interrupt the flow of current during fault conditions, like short circuits or overloads, preventing damage to downstream components. These are commonly used in AIS, particularly for circuits from 800 to 10,000 Amps. They are known for their ability to interrupt high fault currents and their relatively compact size. While more common in medium voltage applications, vacuum circuit breakers are also sometimes used in AIS.
Features of Circuit Breaker in Air Insulated Switchgear
The air insulated circuit breaker is 12KV 630A, which adopts vacuum arc extinguishing method, and the material recovery and degradation rate reaches over 95%. Air insulated circuit breaker contains no sulfur hexafluoride (SF6) greenhouse gas or solid epoxy resin waste, achieving remarkable energy conservation and emission reduction effects.
Components of Circuit Breaker in Air Insulated Switchgear
Circuit Breakers: Safely deviations from normal circuit operations by breaking the flow of current to open the circuit when a fault occurs.
Busbars: They serve in the transmission of very high currents through the shift gear assembly with great efficiency and minimal losses.
Current transformers (CTs): Offer current readings for monitoring and protective purposes.
Voltage Transformers (VTs): Reduce voltage for metering and control apparatus.
Relays: Provide automatic protection functions by abnormal condition recognition.
Enclosures: Prevents personnel and the environment from unwanted contact and serious harm while giving physical support and protection to the electrical components.
