Detection device for testing working state of substation SF6 sensor

Abstract

The invention provides a detection device for testing the working state of a substation SF6 sensor. The detection device comprises a gas storage mechanism for storing an SF6 gas and an SF6 sensor detection mechanism; a detection gas hood is provided with a gas inlet, the gas storage mechanism is provided a gas outlet, the gas outlet is provided with a control valve for controlling the output of the SF6 gas in the gas storage mechanism, and the output end of the control valve is connected with the gas inlet of the detection gas hood through a conduit; a test plate is arranged in the gas hood ofthe detection gas hood, and a display screen and a handle are arranged on the external surface of the detection gas hood; the display screen and the SF6 sensing tester are respectively connected withthe controller; and the controller obtains the concentration information of the SF6 gas in the gas hood through the SF6 sensing tester and displays the obtained concentration information on the display. The detection device for detecting the substation SF6 sensor has the advantages of shortening of the detection time, increase of the working efficiency, ensuring of the safety of personnel, ensuring of the detection accuracy, and maintenance of the safe running of a power grid.

Description

technical field [0001] The invention relates to the field of substation detection, in particular to a detection device for testing the working state of an SF6 sensor in a substation. Background technique [0002] SF 6 Alarm instrument: SF 6 The function of the alarm is to detect SF 6 The gas content, when SF in the air 6 When the gas content exceeds the set value, an audible and visual alarm will be issued, which can effectively prevent poisoning accidents and ensure the safety of personnel's life and property. [0003] Substation GIS equipment has many advantages such as fewer stations, compact structure, easy maintenance, high reliability, and long equipment life cycle. With the promotion of intelligent substations, more and more substations use GIS equipment. To prevent SF in GIS equipment 6 Gas leaks to protect the lives and property safety of staff, and the GIS high-voltage equipment room must be equipped with SF as required 6 Alarm instrument. [0004] SF6 gas c...

AI Technical Summary

Problems solved by technology

The current detection method needs to consume too much SF 6 Gas, and spend a lot of time, taking 220kV substation as an example, the whole station SF 6 It takes about 14L of SF to detect all the working status of the sensors 6 Gas, the more it takes 200 minutes, it will take nearly half of the time just to inflate it back and forth

[0009] In the prior art, with some dedicated SF 6 Gas detection equipment, dedicated SF 6 Sensor detection equipment is bulky, heavy, and expensive, and the special equipment is bulky and inflexible, which cannot meet the needs of on-site use
