Frame circuit breaker manufacturers analyze the structure and operating mechanism of frame circuit breakers

Frame breakers are generally rated at 1000-2000A, high voltage, large blocks and make a sound when they act. Those who are unaware may become mysterious, dangerous, not to be moved around and as far away as possible. In fact, frame breakers are still safe. High voltage, high current, but if you really understand his principle and structure, you will slowly accept, the following frame circuit breaker manufacturers Rui Rui electrical to tell you.


1, frame circuit breaker structure.


The frame circuit breaker structure is made of steel plates to reduce the size of the breaker and make it look compact, with double insulation to isolate the power and improve safety, completely separating the upper layer and the upper layer. The entire circuit breaker has the same height and depth characteristics, ideal for installation in a 500 mm deep distribution panel. With a width of 324 mm rated for a maximum current of 2000 A, the extractable circuit breaker can be installed in distribution panels with a bulkhead width of 400 mm, a compact size that can replace the previous air circuit breakers.

2. Working mechanism of frame type circuit breaker.


The working mechanism is of the energy storage type. This means that the spring energy is operated with a pre-stored spring, either manually by operating the handle on the front plate or electrically with a geared motor. The brake spring stores the automatic energy during operation by means of a closing and braking coil mounted inside the working mechanism. You can use a geared motor to store the spring energy. The circuit breaker can be operated remotely and, if necessary, in conjunction with a monitoring system.


3. The next operating cycle does not require spring energy storage again:.


(1) Initially, the circuit breaker is in brake spring storage: close the brake


(2) Initially, the circuit breaker is in a state of stored energy storage in the closed circuit spring.


This operating apparatus is fitted with both electromechanical anti-bounce devices and can be used for the entire range.
