Electrical equipment SF6 gas leak detecting device and SF6 gas collecting method

Abstract

The invention relates to an electrical equipment SF6 gas leak detecting device and belongs to the field of detecting electrical equipment. The electrical equipment SF6 gas leak detecting device is composed of a gas collecting groove, a flow guiding pipe, a gas collecting barrel and an SF6 gas quantitative and qualitative leak detector. The gas collecting groove is arranged above the flow guiding pipe which is arranged on the gas collecting barrel. The angle between the gas collecting groove and the flow guiding pipe is 105 degrees and the gas collecting barrel is connected with the SF6 gas quantitative and qualitative leak detector. The electrical equipment SF6 gas leak detecting device can be fixedly installed at the lower end of an electrical device which is suspected of leak for a long time and continuous gas sampling is carried out. Gases are accurately guided, the collecting pertinence is high, the collecting quantity is comprehensive, reaction is fast and efficiency is high.

Description

Technical field [0001] The invention belongs to the field of electrical equipment detection, and specifically relates to a combined electrical appliance SF 6 Gas leak detection device. It is widely used in large-scale step-down stations, power plants, power station combined electrical appliances (GIS) insulation medium SF 6 In the gas pipeline of heavy gas recovery and detection equipment in gas and other fields. Background technique [0002] When SF 6 When the gas leaks, the relevant personnel can only use the leak detection instrument on the equipment or on-site to conduct on-site leak detection. The length of the instrument probe, the mobility and mobility of the personnel are limited, and there are unsafe factors, which cannot be uninterrupted and targeted. Accurately capture and locate leaks or micro-leaks. [0003] SF in insulation medium of power system GIS and circuit breaker 6 Wide application of gas, SF 6 Gas leakage will also exist at the same time during operation. In ...

[0002] When SF 6 When a gas leak occurs, the relevant personnel can only use the leak detection instrument on the equipment or on site for on-site leak detection. The length of the instrument probe and the mobility and mobility of the personnel are limited, and there are unsafe factors. Accurately capture and locate leaks or micro leaks

[0003] SF in power system GIS and circuit breaker insulation medium 6 Wide application of gas, SF 6 Gas leakage will also exist during operation. In addition to the allowable leakage value, abnormal moderate, severe leakage or even micro leakage is absolutely not allowed during the operation of the equipment. Personnel must accurately check the SF of the equipment during operation. 6 The pressure value is compared between the time interval and other conditions. If a leak occurs or an automatic alarm occurs, it is necessary to find out the exact leak point and then maintain it quickly. This increases the difficulty of the targeted inspection of gas leaks. The harsh accuracy makes Manual detection increases the huge physical strength, energy, and time of personnel, and the accuracy is not high, which affects the health of personnel, time-consuming and labor-intensive, but the effect is not good
