Multi-point monitoring detecting device for sulfur hexafluoride gas leakage monitoring alarm

Abstract

The invention relates to a multi-point monitoring detecting device for a sulfur hexafluoride (SF6) gas leakage monitoring alarm. The multi-point monitoring detecting device for the SF6 gas leakage monitoring alarm comprises a shell; the shell is internally provided with a processing device and a processing device electrically connected with the output end of the processing device; the upper end of the shell is provided with a wireless receiving device; the wireless receiving device is provided with three monitoring sensors corresponding to blind holes; the lower ends of the monitoring sensors are inserted in the blind holes and connected with the wireless receiving device; each monitoring sensor consists of a housing, a gas sensor for monitoring SF6 gas and a gas calibration sensor for calibrating the SF6 gas which are installed in the housing, a wireless signal transmitting device, a power device and a connecting device. The multi-point monitoring detecting device for the SF6 gas leakage monitoring alarm remotely transmits the monitoring data of multiple sites to the receiving end of the alarm through the connecting device and the wireless transmitting device, and stores the monitoring data through the storing device in the alarm, so the detection range of the alarm is greatly enlarged, and the data statistics is convenient.

Description

technical field [0001] The invention relates to a multi-point monitoring and detecting device used for an SF6 gas leakage monitoring and alarming device. Background technique [0002] For the usual monitoring of SF6 gas, a constant voltage is applied between the two monitoring electrodes to break down the air and then maintain the current between the two electrodes. When there is SF6 in the air, since SF6 is an insulating gas , it will reduce the current between the electrodes, and through the magnitude of the current and a comparative analysis with the SF6 leakage value, it can be known whether the SF6 leakage exceeds the standard. However, most of the ordinary alarm monitoring devices are fixed inside the alarm, which not only affects the monitoring effect, but also cannot monitor multiple locations at the same time, and cannot store monitoring data for a period of time, which greatly limits the monitoring range.
