Recyclable SF6 gas discharging device

Abstract

The invention relates to a recyclable SF6 gas discharging device which comprises a gas recycling bottle, a high-pressure gas pump communicated with the gas recycling bottle through a first high-density plastic pipe, and a gas flow control valve communicated with the high-pressure gas pump through a second high-density plastic pipe. The recyclable SF6 gas discharging device is convenient to carry and easy to operate; the working efficiency is greatly improved; the human safety is guaranteed; the environment pollution is avoided; the signal transmission precision is guaranteed, and the working efficiency is effectively improved; discharged SF6 gas can be recycled; the SF6 gas is prevented from being directly discharged and harming the human safety; the atmospheric environment is protected; and the green and environmentally-friendly overhaul is realized.

Description

[0001] technical field [0002] The invention relates to a recyclable SF6 gas deflation device. Background technique [0003] When the SF6 equipment in the substation is overhauled, it is necessary to send the low pressure alarm and blocking signal of the SF6 density relay to the protection device to check the correctness and reliability of the low pressure alarm and blocking signal circuit. This work is essential and very important A task; when transmitting signals, maintenance personnel often use screwdrivers or other tools to push open the self-sealing valve at the inflation port of the equipment to deflate, and simulate the decrease of the pressure value to send a corresponding signal; If the pressure value in the density meter does not reach the specified value, it needs to be inflated and deflated repeatedly, resulting in low work efficiency, and it is easy to damage the sealing performance of the self-sealing valve port of the equipment; because the discharged SF6 gas...

[0003] When the SF6 equipment in the substation is overhauled, it is necessary to send the low pressure alarm and blocking signal of the SF6 density relay to the protection device to check the correctness and reliability of the low pressure alarm and blocking signal circuit. This work is essential and very important A task; when transmitting signals, maintenance personnel often use screwdrivers or other tools to push open the self-sealing valve at the inflation port of the equipment to deflate, and simulate the decrease of the pressure value to send a corresponding signal; If the pressure value in the density meter does not reach the specified value, it needs to be inflated and deflated repeatedly, resulting in low work efficiency, and it is easy to damage the sealing performance of the self-sealing valve port of the equipment; because the discharged SF6 gas enters the equipment Excessive high temperature decomposition will form toxic gas, which will cause personal injury to the maintenance personnel who carry out this work, and the emitted SF6 gas will also cause air pollution
