Metal particle harmless experimental apparatus and method

Abstract

The invention provides a metal particle harmless experimental apparatus and method, allowing ratio and pressure of mixed gas to be adjusted as required, allowing various metal particle experiments tobe carried out and allowing metal particle experiments to be implemented in different mixed gas environments. The apparatus comprises an SF6 mixed gas charging and recycling device, a metal chamber, an electrode module, an adsorbing device, and a metal particle capture device; the metal chamber includes a left gas compartment and a right gas compartment each of which is fitted with an insulator; the metal particle capture device is mounted in the right gas compartment; the adsorbing device is mounted in the left gas compartment; the SF6 mixed gas charging and recycling device is connected to the left and right gas compartments of the metal chamber; the electrode module is mounted in the metal chamber and is coaxial to the metal chamber. The metal particle harmless experimental apparatus and method allow metal particle harmless experiments to be efficiently carried out on mixed gases different in concentration and pressure, allows the mixed gases to be recycled to increase resource utilization and save experiment cost, and allows substantially zero emission of SF6 to the air.

Description

technical field [0001] The invention relates to the technical field of gas-insulated and enclosed transmission lines, in particular to an experimental device and method for harmless metal particles. Background technique [0002] Gas insulated metal enclosed transmission line (GIL) is applied as a new type of power transmission technology, using SF 6 gas or SF 6 and N 2 High-voltage, high-current power transmission equipment with mixed gas insulation and coaxial arrangement of shell and conductor has outstanding features such as large transmission capacity, low loss, small footprint, flexible layout, and environmental friendliness. Since the 1970s and 1980s, many countries have successively put GIL into the practical process. After nearly half a century of development and application, the voltage level of transmission lines has been continuously improved, and the GIL transmission method has become more mature and stable. It has been widely used all over the world. [0003...

AI Technical Summary

Problems solved by technology

On the one hand, GIL will produce some metal debris or particles during transportation, assembly, and operation; on the other hand, SF 6 The gas also has some defects: first, the liquefaction temperature is high, and it is easy to liquefy when used in the cold winter season in the alpine region, which poses a serious threat to the safe operation of power equipment; second, SF 6 The gas is a very strong greenhouse gas, and its GWP value is the equivalent of CO 2 23,900 times that of the Kyoto Protocol adopted in 1997, the SF 6 The gas is listed as a gas that requires global control; the third is that it is sensitive to the unevenness of the electric field in the power equipment; the fourth is that it will decompose under the continuous action of the high-temperature arc
