Abstract

The invention belongs to the field of a circuit breaker control system, and in particular relates to an intelligent monitoring system of a switch of a branch circuit. The intelligent monitoring system comprises a circuit breaker and a controller, wherein the circuit breaker is arranged on the branch circuit and comprises a current transformer and an analog to digital converter, the current transformer and the analog to digital converter are connected with the controller, the controller is used for controlling the circuit breaker to be switched off and on and comprises a control module, the current transformer transmits a detected current signal to the analog to digital converter, the analog to digital converter is used for converting the current signal into a digital signal and transmitting the digital signal to the control module of the controller, and the control module compares the digital signal with a preset original signal and controls the circuit breaker to be switched on and off. The intelligent monitoring system disclosed by the invention has the advantages of carrying out real time monitoring on the current of the branch circuit in a switch cabinet, preventing the switch cabinet and a current main circuit from being damaged due to overlarge current of the branch circuit, being capable of realizing automatically switching off and manually controlling the circuit breaker to switch off, improving the safety of the switch cabinet and prolonging the service life.

Description

technical field [0001] The invention belongs to the field of circuit breaker control systems, in particular to an intelligent monitoring system for branch circuit switches. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. [0003] A general switch cabinet is provided with a main line of current and several branch lines, and the switch cabinet will be damaged when the current load of the branch lines is too large. Contents of the invention [0004] The problem to be solved by the invention is to monitor the current size of the current branch line of the switch c...
