Online monitoring system for high-voltage isolator

Abstract

The invention discloses an online monitoring system for a high-voltage isolator. The online monitoring system comprises an induction power module, a Zigbee radiofrequency module, an acceleration sensor module, an STM32 controller module and an upper computer module. The STM32 controller module is connected with all of the induction power module, the Zigbee radiofrequency module and the acceleration sensor module. The induction power module powers the STM32 controller module. The acceleration sensor module transmits acceleration signals to the STM32 controller module, and the STM32 controller module transmits the acceleration signals to the Zigbee radiofrequency module. The Zigbee radiofrequency module is connected with the upper computer module and transits the acceleration signals to the upper computer module. The online monitoring system allows for intelligence of continuous power supply and wireless data transmission, and is simple to implement and high in safety and reliability.

Description

technical field [0001] The invention belongs to the field of electronic technology, in particular to an online monitoring system of a high-voltage isolating switch. Background technique [0002] The high-voltage isolating switch is a very important switching device in the power system, and it is the most used primary equipment in the power grid. In the system, it mainly plays the role of isolating voltage to ensure the safety of high-voltage electrical appliances and devices during maintenance work. Due to the large amount of use and high requirements for work reliability, it is necessary to strengthen the monitoring of the operation of the isolating switch, do a good job of maintenance, eliminate hidden dangers of equipment failure in time, and carry out regular maintenance and preventive tests, so as to reduce the risk of accidents caused by the isolating switch. probability of occurrence. [0003] Due to technical and maintenance reasons, the isolating switch is prone t...

AI Technical Summary

Problems solved by technology

[0003] Due to technical and maintenance reasons, the isolating switch is prone to operation jamming, insufficient opening and closing, refusal to open and close, different phases of three-phase mechanical actions, poor contact between moving and static contacts, heating of the conductive circuit, broken porcelain bottle, and pull-out of the switch on the power supply side. Long arc time and other defects, resulting in electrical accidents

Once the isolating switch fails, whether the fault can be quickly and accurately identified and eliminated, and the operation of the isolating switch can be restored in the shortest possible time will seriously affect the safe and stable operation of the power grid.
