High-voltage isolation switch vibration state monitoring system

Abstract

The invention discloses a high-voltage isolation switch vibration state monitoring system. The system comprises a control detection system composed of a temperature sensor, a vibration acceleration transducer, a knife switch adjusting device and a control detection plate, a laser energy supply system, and a monitoring system arranged at a master control chamber of a transformer station. The temperature sensor is connected with the surface of a high-voltage isolation switch, the vibration acceleration transducer and the knife switch adjusting device are respectively connected with the knife switch of the high-voltage isolation switch, output signals of the temperature sensor and the vibration acceleration transducer are respectively sent to the monitoring system through the control detection plate, the control detection plate controls the knife switch adjusting device to act according to the output signals of the vibration acceleration transducer, and the laser energy supply system supplies power to the control detection plate. According to the invention, workers do not have to be dispatched to a field, the labor and time cost is reduced, and the automation level is improved.

Description

technical field [0001] The invention relates to the field of substation automatic monitoring, in particular to a vibration state monitoring system of a high-voltage isolation switch. Background technique [0002] With the transformation of urban and rural power grids and the promotion of substation automation technology, there are more and more unattended substations. The current unattended substations generally have the following automation systems: substation integrated automation system, microcomputer anti-misoperation locking system, part The substation also has a fire prevention and anti-theft system (remote viewing). [0003] The isolating switch is very important and has the largest number of primary equipment in the substation. Due to equipment manufacturing, environmental pollution, foundation deformation, long-term operation, severe overload operation, contact oxidation, arc impact, etc., the isolating switch is closed when it is closed. There are problems such as...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a vibration state monitoring system of a high-voltage isolating switch, which can solve the problems of the prior art isolating switch monitoring system judging that the isolating switch knife is not closed properly, over-positioned, and contacts are loose through video monitoring. The reliability is low, and staff still need to be dispatched, and it cannot be fully automated.
