Gas water content detection device for sulfur hexafluoride circuit breaker

Abstract

The invention discloses a gas water content detection device for a sulfur hexafluoride circuit breaker. The device includes a gas collection device for collecting sulfur hexafluoride gas from a gas chamber of the sulfur hexafluoride circuit breaker as a monitoring sample, a water content detection device for detecting the water content in the monitoring sample collected by the gas collection device, and a control device for controlling the gas collection device, the water content detection device and analyzing data detected by the water content detection device. After the gas collection device collects the monitoring sample, the water content of the monitoring sample can be directly detected through the water content detection device, the monitoring sample can be discharged back into the gas chamber after detection is completed, and sulfur hexafluoride gas does not need to be consumed.

Description

technical field [0001] The invention relates to the technical field of circuit breaker detection devices, in particular to a detection device for the water content of sulfur hexafluoride circuit breaker gas. 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 blown circuit breakers. Sulfur hexafluoride circuit breakers have been widely used in electrical equipment with a voltage level of 63-500kv in China. 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 chemical reaction of sulfur hexafluoride gas decomposition products to produce toxic compounds; Corrosion; moisture damages the insulation of equipment; moisture affects the breaking performance of the switch; moisture reduc...

AI Technical Summary

Problems solved by technology

[0004] The invention mainly solves the technical problem that the existing detection device for the water content of the sulfur hexafluoride circuit breaker takes a long time for a single detection and needs to consume a certain amount of sulfur hexafluoride gas; it provides a water content detection device for the sulfur hexafluoride circuit breaker gas 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
