The invention discloses a gas water content detection device for a sulfur hexafluoride circuit breaker, comprising a gas collection device for collecting sulfur hexafluoride gas from a gas chamber of a sulfur hexafluoride circuit breaker as a monitoring sample, and a gas collection device for collecting the gas. A water content detection device for detecting the water content in the monitoring samples collected by the device, and a control module for controlling the gas collection device, the water content detection device and analyzing the data detected by the water content detection device. In the present invention, after the monitoring sample is collected by the gas collection device, the water content of the monitoring sample can be directly detected by the water content detection device, and the monitoring sample can be discharged back into the gas chamber after the detection is completed, without consuming sulfur hexafluoride gas .
Description
technical field [0001] The invention relates to the technical field of circuit breaker detection devices, in particular to a gas water content detection device for sulfur hexafluoride circuit breakers. Background technique [0002] High-voltage circuit breakers can be divided into circuit breakers, compressed air circuit breakers, sulfur hexafluoride circuit breakers, vacuum circuit breakers and magnetic blower circuit breakers. In the electrical equipment of 63~500kv voltage level in China, the application of sulfur hexafluoride circuit breaker has been quite common. When the water content of the gas in the sulfur hexafluoride circuit breaker reaches a certain level, it will cause serious adverse consequences, mainly in the following aspects: moisture causes the decomposition of sulfur hexafluoride gas to react and produce toxic compounds; moisture causes chemical damage to the equipment Corrosion; moisture damage to equipment insulation; moisture affects the breaking perf...
