Abstract

The invention discloses an online monitoring system for a sulfur hexafluoride switch. The online monitoring system comprises a first gas sampling device which is connected with a sulfur hexafluoride switch to be detected by a gas fetching pipe, wherein the gas fetching pipe is provided with a gas fetching valve; the gas sampling device is connected with a laser gas analyzer by an optical fiber. The online monitoring system for the sulfur hexafluoride switch comprises the gas sampling device which is connected with the sulfur hexafluoride switch to be detected by the gas fetching pipe; the gas sampling device is connected with the laser gas analyzer by the optical fiber; the operated SF6 switch is monitored by monitoring and analyzing the concentration of SF6 gas in the operated SF6 switch. The monitoring system adopts a laser technology to monitor the concentration of the gas, is simple in structure and is low in cost; meanwhile, the monitoring accuracy is improved.

Description

technical field [0001] The invention relates to an on-line monitoring system for a sulfur hexafluoride switch. Background technique [0002] The existing on-line monitoring system of sulfur hexafluoride (SF6) switch with multiple monitoring points is to arrange monitoring instruments or sensors at each monitoring point to measure and analyze the gas concentration or leakage in the SF6 switch at the monitoring point. After the data is analyzed, the measurement data is transmitted to the system host or server through the communication cable. Since the monitoring instruments or sensors used generally include measurement sensitive components, signal processing units, data analysis units, signal transmission and transmission units, etc., there are common problems such as complex system composition, excessive cost investment, and high failure rate. Contents of the invention [0003] The object of the present invention is to provide an on-line monitoring system for sulfur hexafl...
