Abstract

The invention relates to a high-voltage breaker on-line detection system and method. The system comprises a sensor module, a first switch power supply, a second switch power supply, a central processing circuit and a host computer. The sensor module is arranged inside the control box of a high-voltage breaker and connected with the central processing circuit. The first switch power supply is connected with the central processing circuit. The central processing circuit is wirelessly connected with the host computer. The second switch power supply is connected with the host computer. The high-voltage breaker on-line detection system and method can detect the loop circuits inside the high-voltage breaker in a real-time manner when electric power equipment is on. The electrical parameters of the high-voltage breaker during opening or closing processes can be acquired. The running state of the high-voltage breaker can be judged. Electric power safety accidents caused by faults of the high-voltage breaker can be effectively prevented.

Description

technical field [0001] The invention relates to the field of switch testers, in particular to an on-line detection system and method for a high-voltage circuit breaker. Background technique [0002] Opening / closing coil burning accidents often occur during the operation of the power system. The opening / closing coil is the action actuator of the power system control and protection circuit, and is also one of the important components in the operating mechanism of the high-voltage circuit breaker. It is very important for the safety and reliability of the power system. Running plays a pivotal role. [0003] The opening / closing coil is an instantaneous working element, and the opening / closing coil often burns out during operation. As we all know, the opening / closing coils are designed for short-time energization, and the currents of the opening / closing coils are also different due to the different operating mechanisms. The burning of the opening / closing coil is mainly caused b...
