Abstract

The invention discloses an experimental platform for simulating and monitoring the movement condition of metal particles in GIS, comprising a voltage output and measuring module, a high voltage bushing and switching module, an experimental cavity and a remote monitoring module. Voltage is applied to the high voltage bushing by the voltage output and measuring module and is acted on the experimental cavity via a busbar. The experimental cavity is used for holding a sample table of the metal particles, and the distance between the sample table and a guide rod in the experimental cavity is controlled by changing the number of metal spacers. The movement condition of the metal particles under the action of an electric field is observed by a high-definition wireless video camera via an observation window, and is transmitted to a control terminal via a wireless net for observation and recording. The relationship between a particle movement trail and applied voltage is determined by a high voltage power control cabinet and a camera shooting control terminal. Change of the particle movement trail can be observed by changing applied voltage in real time. The experimental platform solves the difficulty of simulation and monitoring on the movement condition of metal particles in GIS, and the safety of experimenters is ensured by remote control.

Description

Technical field: [0001] The invention relates to the technical field of high-voltage experiments, in particular to an experimental platform for simulating and monitoring the movement of metal particles in GIS. Background technique: [0002] With the continuous improvement of the voltage level of my country's power system, gas-insulated metal-enclosed switchgear (GIS) is more and more widely used in my country's power system. GIS equipment will inevitably produce metal particles inside the equipment during the process of production, assembly, and switching operations. These metal particles move under the action of electric field, which reduces the insulation strength of GIS, so it is very important to grasp the movement of particles in GIS. At present, small models are mostly used to simulate the movement state of metal particles in GIS, which cannot accurately reflect the movement of metal particles in actual GIS, and remote monitoring and control have not yet been realized...
