Why is it necessary to use a circuit breaker with a split release when removing the non fire circuit? What circuit breaker is used if the fire control circuit is controlled?
The circuit breaker can be used to distribute electricity, not frequently start asynchronous motors, the protection of the power line and a motor, can automatically cut off the circuit when they occur serious overload or short circuit and under voltage fault combination, its function is equivalent to the fuse switch and less thermal relay etc.. Moreover, after breaking the fault current, there is no need to change the components. At present, it has been widely used.
The circuit breaker (English Name: circuit-breaker circuit, breaker) refers to the closing, carrying and breaking current conditions and normal circuit switch device, load and breaking current loop abnormal conditions within the stipulated time. The circuit breaker is divided into high voltage circuit breaker and low voltage circuit breaker according to its range of use. The demarcation line of high and low voltage is fuzzy. Generally, more than 3kV is called high-voltage equipment.
The fire is weak loop fire fighting equipment and fire alarm controller communication fire alarm signal line, a loop with 200 points (smoke detector, temperature detector, input module and so on) and 15 fire display panel.
A circuit breaker with a shunt release has an array of coils to receive an alarm signal for power on and off, and the fire is dual loop switching with the ATS.
