Abstract

The invention relates to a GIS equipment fault simulation test system which is characterized by comprising a piece of single-phase complete interval GIS equipment, a complete current boosting apparatus and a complete voltage boosting apparatus. Power, after voltage regulation by a voltage regulator, is output through a gas test transformer. The current boosting apparatus is sleeved in a GIS pipe female housing so as to achieve an aim of current boosting. In such work condition, the operation work condition is simulated through the voltage boosting apparatus and the current boosting apparatus, stimulants such as tip ends and particles are built in a GIS bus test segment for charged detection test study. On the basis of the test study, an effective detection means of GIS equipment internal typical faults and corresponding determination bases are proposed. The GIS equipment fault simulation test system can be used for performing fault recurrence and charged detection work under rated operation voltage and operation current, and also be used for performing insulation characteristic test study, so as to realize validation research on the field insulation detection effective means.

Description

Technical field [0001] The invention relates to a GIS equipment failure simulation test system, which belongs to the electric power technology field. Background technique [0002] SF6 gas insulated fully enclosed combined electrical appliances are referred to as GIS (gas Insulated Switchgear), which is an important part of substation equipment. It is composed of circuit breakers, busbars, isolating switches, current transformers, voltage transformers, arresters, bushings and other high-voltage electrical appliances. Since the 1980s, GIS electrical equipment has developed rapidly in my country. Although GIS equipment has many advantages such as small footprint and high reliability. However, due to the fully enclosed nature of GIS equipment, there are also some shortcomings. For example, it is difficult to find fault points and overhaul after an accident occurs. The power outage range when handling faults is larger than that of traditional open electrical equipment and the overha...
