Abstract

The invention relates to a large multifunctional environmental simulator for electrical tests, which comprises an environmental stimulation chamber and is characterized in that an air heat-exchange circulation system and an ice-melting system are arranged in the environmental stimulation chamber; and the environmental stimulation chamber further comprises an ice-coating, rain-exposing and ultrasonic-atomizing system, a water treatment system, a heat-fogging system, a cooling water circulation system, a refrigeration system, a vacuuming and defogging system, a measurement and control system and an ultra-high voltage power supply system for providing a high-voltage charging state for test-pieces. By achieving the skillful coordination among the systems and the uniform operation control by the measurement and control system, the large multifunctional environmental simulator integrates various testing functions of environmental simulations, such as high-altitude, ice-coating, contamination, rain-exposing and other simulations into a whole. Therefore, the invention is widely suitable for the testing process for large multi-parameter environmental simulations.

Description

technical field

[0001] The invention relates to an environment simulation device, in particular to a large-scale multifunctional environment simulation device for electrical tests. Background technique

[0002] With the rapid development of industry and agriculture, the pollution of the atmospheric environment has also intensified. Complicated weather and polluted environment will significantly reduce the electric strength of insulators, resulting in flashover of insulator strings, leading to large-scale power outages. In addition, due to the increasing demand for electricity, UHV power transmission has become an important means to improve the transmission capacity of my country's power grid, and UHV lines have higher reliability requirements than high-voltage lines. In the UHV state, the pollution discharge of insulators in different environments is very important to the design, safe operation and development of the power system. This is also an important consideration for...
