Problems solved by technology

After a false alarm is generated, the staff arrives at the scene, and according to the alarm signal of the UHF partial discharge on-line monitoring device, the integrated SF 6 Gas detection data, troubleshooting, time-consuming and labor-intensive
[0007] In addition, adsorbents are generally installed inside the GIS. In the case of less decomposition gas, the decomposition gas has been adsorbed before detection, and it is difficult to verify the occurrence of partial discharge in the detection of gas decomposition products outside the GIS.
The existing technology does not take into account the presence of adsorbents in the GIS gas chamber in design

Abstract

A GIS partial discharge comprehensive online monitoring device includes: a detection unit, a control unit, a power taking unit, a first cavity and a second cavity. The monitoring device determines the detection results on the basis of synthesizing the detection data of multiple sensors. This determination method can eliminate most false alarms, reduce the number of inspections and the workload of the staff. The device also sends the inspection data to the upper computer through the communication module. , so that the staff on duty next to the host computer can get the alarm information at the first time. The device obtains electric energy from the internal conductor of the GIS through the power taking unit, and can work without external power supply, without adding cables, and without destroying the existing GIS air chamber structure, which is convenient for the reconstruction of existing equipment. In the device, the detection unit is arranged inside the first cavity, above the adsorbent, so that the decomposed gas can be detected first and then adsorbed. Compared with the prior art, the decomposition of the GIS gas can be more accurately detected.

Description

A GIS partial discharge comprehensive online monitoring device technical field The present invention relates to GIS partial discharge detection technical field, particularly a kind of applied to GIS partial discharge integrated online monitoring device. Background technique [0002] The inner center of the GIS is a conductor, the gas chamber is filled with insulating gas, and the interior is provided with a support insulator and a basin-type insulator. exist During operation, due to burrs on the conductor, metal particles in the gas chamber, floating potential, defects on the insulator, etc. This leads to the occurrence of corona discharge, creeping discharge, hole discharge, metal particle discharge and other problems in the GIS. if SF 6 gas exists Moisture, the decomposition products react with moisture to form HF and SO during discharge 2 , seriously endanger the safe operation of electrical equipment. [0003] Continuous partial discharges may occur withi...
