Micro water treatment system for combined transformer substation

Abstract

The invention discloses a micro water treatment system for a combined transformer substation. The system has a simple structure, contains a reliable detection assembly and a simple and efficient drying structure, and has a low overall cost and a high efficiency. The system comprises a micro water detection assembly, the lower probe tube of the micro water detection assembly is connected with a drying assembly, and the outlet of the drying assembly is connected with the gas inlet of a GIS gas chamber; the micro water detection assembly is connected with the gas outlet of the GIS gas chamber through a GIS gas chamber joint; the micro water detection assembly comprises a detection chamber, a flange, a protruding neck, an upper cover, a filter screen, a pedestal, a bracket, a motor, a drivinggear, a driven gear, a screw rod, a lead screw lifting platform, a silicone ring, a fan, a bypass tube, the lower probe tube and a gas discharge channel; an emptying port is arranged at the bottom ofthe lower probe tube, and the emptying port is connected with the drying assembly through a connector, and the connector assembly includes a detection chamber connection joint and a dryer joint; and agas discharge port is arranged at the end of the dryer joint, the gas discharge port is connected with the inlet of the absorbing device of the drying assembly, and a drying agent is arranged in theabsorbing device.

Description

technical field [0001] The invention relates to a micro-water treatment system, which is specifically used for the micro-water treatment of a GIS combined substation. Background technique [0002] Under normal conditions, SF6 gas is colorless and odorless, and has good insulation performance and arc extinguishing performance. Once the moisture in the atmosphere is immersed or the surface of the solid medium is damp, the electric strength will be significantly reduced. The circuit breaker is an outdoor device. When the temperature drops suddenly, the excess water of SF6 gas may condense on the surface of the solid medium and cause a flashover. In severe cases, the circuit breaker may explode. Pure SF6 gas, during operation, will be decomposed into monomeric fluorine, sulfur and fluorine-sulfur compounds after being subjected to arc discharge or high temperature, and will be combined into stable SF6 gas after the arc disappears. When the gas contains moisture, the fluorine-su...

Problems solved by technology

[0005] The current micro-water treatment is to completely extract the gas in the GIS gas chamber for drying on a large scale. This system is too complicated, and it cannot reliably realize the treatment after detection, resulting in a huge, high-cost and low-efficiency micro-water treatment system.
