Environment-friendly sulfur hexafluoride comprehensive detection device

Abstract

The invention provides an environment-friendly sulfur hexafluoride comprehensive detection device. The environment-friendly sulfur hexafluoride comprehensive detection device comprises a sulfur hexafluoride gas comprehensive detection module and a tail gas purification and recovery module, the tail gas purification and recovery module comprises a buffer tank, a compressor connected with an exhaust port of the buffer tank, a purifier connected with an exhaust port of the compressor, a recovery bottle connected with an exhaust port of the purifier and a control system; wherein a pressure sensor is installed on one side of the buffer tank, an electromagnetic valve is installed between the buffer tank and the compressor, and the pressure sensor, the electromagnetic valve and the compressor are in control connection with the control system. When the pressure reaches a set value, the control system controls the electromagnetic valve and the compressor to recycle gas into the recycling bottle; a quick-plug connector is arranged at an air inlet of the recycling bottle, and the recycling bottle is in quick-plug fit with the air channel pipeline through the quick-plug connector. The device is reliable in work and simple in operation, and integrates the functions of sulfur hexafluoride gas purity, humidity and decomposition product detection and detection tail gas purification and recovery, thereby facilitating on-site detection and recovery.

Description

technical field [0001] The invention relates to electric power technology, in particular to an environment-friendly comprehensive detection device for sulfur hexafluoride. Background technique [0002] In the power industry, sulfur hexafluoride gas is widely used in various high-voltage electrical equipment due to its excellent insulation and arc extinguishing properties, but at the same time, sulfur hexafluoride is also an important greenhouse gas that affects the global environment. One of the greenhouse gases. In addition, sulfur hexafluoride gas in electrical equipment may also produce a variety of toxic or highly toxic gases due to equipment discharge, overheating and other faults. Therefore, workers in the field need to regularly detect sulfur hexafluoride gas in electrical equipment. [0003] However, the existing sulfur hexafluoride gas detection device only detects the equipment, and cannot be integrated with the recovered detection gas. The detected gas is either...

AI Technical Summary

Problems solved by technology

[0003] However, the existing sulfur hexafluoride gas detection device only detects the equipment, and cannot be used as a whole with the recovery of the detection gas. The detected gas is either directly discharged into the atmosphere, or needs to be recovered separately

Among them, direct air discharge will cause environmental pollution; separate recovery requires a separate recovery device connected to the sulfur hexafluoride detection device through pipelines, the operation is cumbersome, and it is easy to cause sulfur hexafluoride gas leakage
