Mechanical electrified excessive moisture treatment device of SF6 device

Abstract

The invention discloses a mechanical electrified excessive moisture treatment device of an SF6 device. The mechanical electrified excessive moisture treatment device comprises a compressible metal container, a mechanical compression module, a control module, a drying-filtering device and a self-sealing interface, wherein the compressible metal container is communicated with the drying-filtering device, the drying-filtering device is connected with the SF6 device through the self-sealing interface, the mechanical compression module decreases or increased the volume of the compressible metal container through circular compression, drives SF6 gas to pass through the drying-filtering device back and forth and is arranged on the compressible metal container. The control module is connected withthe mechanical compression module and control mechanical circular compression of the mechanical compression module. An SF6 metal expander is compressed / restored mechanically and circularly, so that the SF6 gas passes through the drying-filtering device back and forth, non-exhausting treatment of excessive moisture of the SF6 device is achieved, environmental pollution is reduced, the SF6 metal expander does not need power failure in the compression and restoration process, the SF6 gas only needs that the electrified excessive moisture treatment device is connected to an inflation port of theSF6 device, the operation is simple, the cost is low, and the efficiency is high.

Description

technical field [0001] The invention relates to the field of SF6 equipment maintenance, and more specifically, relates to a mechanical charging treatment device for SF6 equipment with excessive water content. Background technique [0002] Due to various reasons, the moisture content of SF6 equipment will increase during operation. When the moisture content exceeds the relevant regulations of the regulations, it is necessary to deal with the moisture exceeding the standard. If the water content of SF6 equipment exceeds the standard, it usually needs to return to the factory for repair or replace SF6 gas on site. The replacement of SF6 gas by SF6 equipment includes recovering SF6 gas, replacing the adsorbent (when conditions permit), vacuuming multiple times, filling with high-purity nitrogen, and finally filling with SF6 gas, and retesting the moisture content of SF6 after standing for 24 hours. The process is complicated. , high processing costs. In addition, the equipment...
