Description

A kind of SF6、O2Online monitoring alarm system

Technical field

It the utility model is related to electrical equipment technical field, more particularly to a kind of SF₆、O₂Online monitoring alarm system.

Background technology

From the sixties in last century, SF₆It is widely used in bulk of worldwide electricity row as extremely superior insulation, arc-extinguishing medium In primary cut-out and transformer in industry.In today, SF₆Gas almost turns into high pressure, extra high voltage circuit breaker and GIS only One insulation and arc-extinguishing medium.

Pure SF₆Gas is colourless, tasteless, non-ignitable, and chemical property is particularly stable at normal temperatures, is 5 times of air specific weight It is more.But in power system, due to SF₆Gas act mainly as insulation and arc-extinguishing medium, electric arc and shelf depreciation, high temperature etc. because Under the influence of element, SF₆Gas can be decomposed.Its analyte generates aggressive electrolyte after meeting moisture, especially some high poisons Property analyte, such as SF₄、S₂F₂、SOF₂、HF、SO₂Deng such as a large amount of suction people, which know from experience, causes dizzy and pulmonary edema, or even stupor and dead Die.

In the interior of opposing seal, due to sluggish in air circulation, SF₆And its analyte deposits indoors, plus SF₆Gas It is colourless, tasteless, so as to produce greatly harm to tour, maintainer.After GIS produces leakage, SF₆Accumulated gases are in terrace Top low layer space, causes ischaemia, makes one to suffocate and cause a serious accident.

Utility model content

The technical problems to be solved in the utility model design is a kind of to be monitored in real time to unattended operation transformer station, switch gear room SF₆、 O₂Online monitoring alarm system, solves existing technical problem.

In order to solve the above technical problems, SF of the present utility model₆、O₂Online monitoring alarm system includes monitoring host computer, long-range Control centre, supervising device, blower fan control system and gas laser detecting system；Supervising device include infrared human body inductor, Alarm lamp and alarm indication screen；Monitoring host computer respectively with remote control center, infrared human body inductor, alarm lamp, alarm indication Screen, blower fan control system connect with gas laser detecting system.Blower fan control system includes controller of fan, axial flow blower； Under the control of controller of fan, axial flow blower is connected by screen pipe with the external world.Traditional Fan Equipment is often for discharge SF₆And caused harmful substance is expelled directly out without any processing after its decomposition, still there is harm in it for environment, In order to prevent the generation of this Harm, so the pipeline of axial flow blower of the present utility model will will can have by screen pipe Evil gas is absorbed, and prevents from causing secondary pollution.Gas laser detecting system includes SF₆Gas collector, O₂Gas collector And synthesis analyser；Synthesis analyser respectively with SF₆Gas collector, O₂Gas collector is connected.Because as generation SF₆Gas When body leaks, operating personnel can not be rested on from the place within leakage point 10m.So when gas laser detecting system detects To SF₆Gas gas leakage concentration is more than 1000ppm or O₂When concentration is less than 18%, certain measure can be taken, until taking After measure leakage stops, the region can be entered.If broken down inside electrical equipment, there is SF certainly in container₆Electric arc point Thing is solved, is being opened after shell is purged, if contaminated part may be contacted in detection, it is necessary to using breathing mask, And protective clothing is dressed.Also, in order to ensure to enter SF₆Worker safety in breaker chamber, it is necessary to enter to interior Row ventilation.According to related request, content of oxygen in air concentration is not lower than 18%.When the oxygen content in air is less than the standard When, corresponding warning device can react in time, such as alarm lamp lights, and the automatic gate for closing breaker chamber does not allow to examine The entrance of survey personnel.

Further, SF is provided with screen pipe₆And SF₆The absorption plant of analyte.Screen pipe can absorb SF₆Gas with And its analyte after being decomposed, prevent that to form corrosive electrolytic confrontation instrument causes further to damage.

Further, controller of fan uses two-wire RS-485 protocol communications.The communication protocol is not limited to, other can Realize that the communication protocol of correlation function can serve as selecting.

Further, gas laser detecting system also includes Temperature and Humidity device；Synthesis analyser and Temperature and Humidity device It is connected.Temperature and Humidity device can preferably monitor the temperature of primary cut-out and transformer local environment, and humidity is prevented Only SF₆Gas can be decomposed after analyte meet moisture after generate aggressive electrolyte.

Further, the humidity regulation scope of Temperature and Humidity device is 0~99%RH and temperature regulating range is -25~99 ℃.Within this range, can be needed voluntarily to adjust setting according to user., can automatic start sky when temperature exceedes the standard of setting Conditioning function simultaneously makes prompting on alarm indication screen.When humidity exceedes the standard of setting, meeting automatic start dehumidifier function is simultaneously Prompting is made on alarm indication screen.

Further, SF₆The detection range of gas collector is 0~9999 × 10^-6(v/_v).Within this range, can basis User needs voluntarily to adjust setting.

Further, O₂The detection range of gas collector is 1~25U%.Within this range, can be needed certainly according to user Row regulation setting.

The beneficial effects of the utility model：After the system, to indoor SF₆Concentration, O₂The multiple parameters such as concentration carry out Accurate monitoring, in the case where communication condition is complete, can in the form of network component monitor center, can be achieved to unattended Transformer station, switch gear room monitor in real time, improve the efficiency of management, improve and safeguard system.Surveillance center, both can be with using database as core Transformer station, the environment and equipment operation condition of switch gear room, can be counted again according to conventional environment, equipment operating data, Analysis, decision-making foundation is provided for manager.Simultaneously drastically increase unattended operation transformer station operation security, particularly pair Reliable guarantee is played in daily tour and the personal safety of attendant.
