Abstract

The present invention relates to a circuit breaker and a method of controlling the same. More specifically, the present invention is to provide a circuit breaker capable of performing an interruption operation and an interruption monitoring function through an integrated control contact for transmitting a control signal, in order to solve the conventional problem, i.e., a structural problem due to separation of control contacts, and a malfunction of a monitoring function when an interlock is set, and a method of controlling the circuit breaker. With such a configuration, the circuit breaker can have a simplified structure, and can be designed and controlled more easily and simply.

Description

technical field [0001] The present invention relates to a circuit breaker and a control method thereof, and in particular, to a circuit breaker capable of performing interruption operation and interruption monitoring functions through an integrated control contact, and a control method thereof. Background technique [0002] figure 1 A sequence diagram illustrating the structure and operation of a circuit breaker according to the prior art. Figure 2A and Figure 2B To illustrate the structure and sequence of operation of a circuit breaker according to the prior art Figure 2A and 2B . image 3 A sequence diagram illustrating the structure and operation of a circuit breaker according to the prior art. [0003] like figure 1 As shown, the existing circuit breaker has the following configuration: a command contact (SW1-OPEN) for opening the circuit breaker and a TRS contact (SW1-TRS-NOW) for the trip relay supervision (TRS) of the circuit breaker separated from each othe...
