SF6 inflation equipment pressure reading automatic remote transmission system and application method

Abstract

The invention discloses an SF6 inflation equipment pressure reading automatic remote transmission system and an application method. The SF6 inflation equipment pressure reading automatic remote transmission system comprises a three-way valve, a pressure transmission module and an on-site processing module, wherein the three-way valve is connected to an inflation port of SF6 inflation equipment, adetection end of the pressure transmission module is communicated with one interface of the three-way valve, an output end of the pressure transmitter module is connected with the on-site processing module, the on-site processing module remotely transmits detected pressure signals to a transformer substation auxiliary equipment monitoring system, and the on-site processing module is additionally provided with a pressure correction element, corrects absolute pressure monitored by the pressure transmitter into relative pressure and remotely transmits the relative pressure. According to the SF6 inflation equipment pressure reading automatic remote transmission system and the application thereof, real-time remote transmission and intelligent alarm of the pressure readings of the SF6 inflationequipment are realized, manual meter reading is replaced, the problems of simplicity, repetition and time consumption of previous operation and maintenance personnel station arrival meter reading aresolved, an SF6 pressure historical curve is automatically generated, the change condition of the readings of the meter is intelligently compared, equipment air leakage is discovered in advance, and the equipment operation reliability is improved.

Description

technical field [0001] The present invention relates to SF 6 Inflatable equipment monitoring and maintenance technology, specifically related to a SF 6 Automatic remote transmission system for pressure indication of inflatable equipment and its application method. Background technique [0002] SF 6 Inflatable Equipment Internal SF 6 Gas is the main insulating medium of the equipment, and its density directly affects the operation stability of the equipment. As the grid continues to evolve, substation SF 6 The number of inflatable devices is increasing year by year. However, existing SF 6 The pressure gauges of inflatable equipment only have alarm and blocking node outputs, and the meter readings cannot be transmitted remotely in real time. Operation and maintenance personnel need to go to the station to carry out meter transcription work, and manually compare the changes in the meter readings, resulting in a workload for operation and maintenance personnel. Large, low...
