An environmentally friendly and intelligent gas property analysis device

Abstract

The invention provides an environment-friendly and intelligent type gas property analyzing device which comprises a switchgear gas chamber. The top and the bottom of the switchgear gas chamber are each provided with a gas chamber switching type valve seat, the bottom of the switchgear gas chamber is connected with the corresponding gas chamber switching type valve seat through a switching type valve seat insulation spacer, and the gas chamber switching type valve seat is connected with one end of a gas circulation pipeline through a gas circulation pipeline lower connector. The other end of the gas circulation pipeline is connected with a gas analyzing device body through a gas circulation pipeline upper connector. The gas analyzing device body is fixed to the tube wall of the switchgear gas chamber through a mounting support. The gas analyzing device body is connected with a gas chamber self-sealing valve through a gas analyzing device lower connector. There is no need to exhaust gases to the outside when the gas property is analyzed, zero leakage can be realized, and entire equipment meets the environment-friendly requirement; the analyzing device can upload data to a background through an intelligent communication interface, and therefore the environment-friendly and intelligent requirements are integrally met.

Description

technical field [0001] The invention relates to a gas property analysis device, in particular to an environment-friendly intelligent gas property analysis device. Background technique [0002] SF6 is commonly used in the high-voltage electrical industry as the insulating gas of metal-enclosed switchgear. During the operation and testing of the equipment, it is necessary to analyze and detect the moisture content and temperature of the insulating gas to ensure that its insulation performance meets the requirements for good operation of the equipment. Now there is an insulation method that mixes SF6 and N2 in a certain proportion to replace pure SF6. This method also needs to detect the concentration of SF6. It is best to monitor the micro water, concentration and temperature in real time and online. In this way, real-time monitoring and real-time alarm can be realized. Some existing micro-water, concentration and temperature testers need to discharge a small amount of insulat...

[0002] SF6 is commonly used in the high-voltage electrical industry as the insulating gas of metal-enclosed switchgear. During the operation and testing of the equipment, it is necessary to analyze and detect the moisture content and temperature of the insulating gas to ensure that its insulation performance meets the requirements for good operation of the equipment. Now there is an insulation method that mixes SF6 and N2 in a certain proportion to replace pure SF6. This method also needs to detect the concentration of SF6. It is best to monitor the micro water, concentration and temperature in real time and online. In this way, real-time monitoring and real-time alarm can be realized. Some existing micro-water, concentration and temperature testers need to discharge a small amount of insulating gas from the switchgear, and flow through the internal sensor of the detection device to realize the detection function. Manually connect the detection equipment and switchgear through the interface, so that a certain amount of insulating gas will inevitably leak during the detection, although it will not affect the insulation performance of the switch, but the accumulation will cause a certain degree of environmental pollution. The way of docking is also not conducive to real-time and online detection
