Treatment system for micro water of GIS air chamber

Abstract

The invention discloses a treatment system for micro water of a GIS air chamber. The treatment system is used for treating micro water in the air chamber of a GIS device to reach the standard value. The system comprises a main pipeline communicated with the air chamber of the GIS device, and a micro water detection pipeline, a sulfur hexafluoride recycling pipeline, a vacuumizing pipeline and a nitrogen exhausting pipeline are connected to the main pipeline in parallel. The far end of the micro water detection pipeline, the far end of the vacuumizing pipeline and the far end of the nitrogen exhausting pipeline are connected to an emptying pipeline; a micro water unit for detecting micro water is arranged on the micro water detection pipeline; a vacuum unit for vacuumizing is arranged on the vacuumizing pipeline, and the far end of the sulfur hexafluoride recycling pipeline is connected to a sulfur hexafluoride gas recycling vehicle; a sulfur hexafluoride filling pipeline and a nitrogen filling pipeline are further arranged on the main pipeline; the system further comprises a heater for heating the air chamber of the GIS device; each pipeline is provided with an electromagnetic valve; and the electromagnetic valves are connected with a controller of a control display unit.

Description

technical field [0001] The invention relates to a micro-water treatment system in a GIS air chamber, which is specifically used for treating the micro-water in the air chamber of GIS (sulfur hexafluoride fully enclosed combined electrical appliances) equipment. Background technique [0002] The safe and stable operation of sulfur hexafluoride fully enclosed combined electrical appliances (GIS) (GASINSULATESWITCHGEAR) is very important to the power system, and it is the fundamental requirement to improve the safety of power supply and meet the reliability of power supply. During the installation process of combined electrical appliances (GIS), due to moisture brought in by insulating parts, moisture brought in by adsorbents, moisture contained in fresh SF6 gas, poor filling process, poor vacuuming process, and incomplete treatment of components such as pipe joints Factors such as the combination of electric appliances (GIS) after commissioning micro water exceeds the standard...

Problems solved by technology

[0004] In the prior art, the treatment capacity for micro water is low, and only small-scale treatment can be carried out, such as adsorption treatment or nitrogen circulation treatment; however, incomplete treatment will be found in many on-site treatment processes; the main reason is that the existing treatment The function of micro-water equipment is not perfect, and the scope of application is narrow
