Abstract

The invention discloses an online monitoring device for mechanic-electrical integrated SF6 density moisture. The mechanic-electrical integrated SF6 density moisture comprises an electronic type density moisture module, a mechanical density module, a joint mechanism and a detection module, wherein the electronic density moisture module, the detection module and the mechanical density module are integrated by using the tailored joint mechanism, and thus the convenience for operation during use is realized. The flexibility and the safety of operation and use are improved by using a self-closed needle valve arranged inside a detection interface of the joint mechanism. Meanwhile, the electronic density moisture module and the mechanical density module are combined for online monitoring; and two paths of monitoring are independently transmitted without mutual interference, and thus the accuracy in detection and the reliability of the detection result are improved. A mechanical dial and digital display provide visual read for operators; and the electronic density moisture module can also be remotely controlled and monitored according to the requirement.

Description

Technical field:

[0001] The invention relates to a SF6 gas monitoring device in high-voltage electrical equipment, in particular to an electromechanical integrated SF6 gas density micro-water online monitoring device for monitoring the temperature and density of SF6 gas in high-voltage electrical equipment in operation and the micro-water value in the gas. Background technique:

[0002] With the continuous improvement of the safety and reliability of high-voltage electrical equipment used in substations due to the operation of the power grid, SF6, as a safe and effective insulation and arc-extinguishing medium, has been widely used in high-voltage electrical equipment at home and abroad, especially in Electric power system, the application volume has reached 95% of the total production. However, due to the quality differences in the manufacture and installation of SF6 electrical equipment and the aging of materials, the leakage of SF6 gas and the increase of moisture in the ...
