Problems solved by technology

[0003] In order to improve the safety of the switchgear, a comprehensive protection system is added in the cabinet. When problems such as overload, overvoltage or undervoltage occur in the circuit, it will automatically trip and cut off the power. However, if the switchgear leaks during use, it will be very Although the current technology provides a leakage protector, it cannot send the leakage situation to the control room in time, so that the administrator cannot grasp the operation status of the switch cabinet in a timely and effective manner, which greatly reduces the safety performance of the switch cabinet

Description

technical field [0001] The invention relates to the technical field of leakage monitoring of switch cabinets, in particular to a leakage monitoring system suitable for low-voltage switch cabinets. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet 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. The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, ...
