Description
Technical Field
[0001] The utility model belongs to the technical field of gas analyzers, and particularly relates to a spectrum type comprehensive gas analyzer for electric power equipment. Background Art
[0002] Power equipment mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment mainly includes power station boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment mainly includes transmission lines of various voltage levels, mutual inductors, contactors, etc. At present, more gas circuit breakers are used in power equipment, such as sulfur hexafluoride circuit breakers. Sulfur hexafluoride circuit breakers use sulfur hexafluoride (SF6) gas as an insulating medium. Whether the sulfur hexafluoride circuit breaker is filled with sulfur hexafluoride gas is a key factor affecting the insulation performance of the circuit breaker, so it is necessary to regularly analyze and detect the gas inside the power equipment.
[0003] The Chinese utility model patent currently announced as: CN215067222U discloses an online gas monitoring device for power equipment faults, which belongs to the technical field of monitoring equipment. This gas online monitoring device can quickly monitor the gas generated by transformer faults, can quickly respond to sudden faults, and can also track trends for chronic work. It has the characteristics of simple and convenient installation, maintenance-free operation, and practical monitoring data. The device can be installed on the upper pipeline of the transformer tap changer and can also be installed on other oil-insulated power equipment, which is of great significance to improving the safety level of power transmission and transformation equipment.
[0004] Although this patent has the function of quickly monitoring the gas generated by transformer failure, there will be residual detection gas inside the air intake pipe before the analyzer detects the gas, which will lead to inaccurate detection. At the same time, due to the lack of gas filtration, a large amount of dust and impurities in the gas will enter the analyzer and affect the accuracy of the detection. Utility Model Content
