An output hole of a powder spraying machine of the system is communicated with an adjustable fan, an output hole of the adjustable fan is communicated with a test tank through an air flue, an output hole of a fog generator is also communicated with the test tank through an air flue; control ends of the powder spraying machine, the adjustable fan, the fog generator, a raining rank, a temperature adjusting device and a pneumatic control unit are connected with a control signal output end of a simulation environment control module through a total control module of an executing mechanism; signal output ends of a temperature sensor, a humidity sensor, a raining amount tester, a barometer, a wind speed and direction sensor and a dust sensor are connected with a signal input end of the simulation environment control module through a data acquiring module. The system is capable of rapidly and accurately simulating the operating environment in the high altitude localities under the condition of low-altitude localities, and is helpful to research the operating environment of the composite insulator in the high altitude localities.

Description

technical field [0001] The invention relates to the technical field of simulation of the operating environment of composite insulators in the electric power industry, in particular to a system and method for simulating the operating environment of composite insulators in high-altitude areas. technical background [0002] With the increasing promotion of high-voltage power transmission and transformation in my country, the external insulation performance of power transmission and transformation equipment has been paid more and more attention to the operation safety of the power grid. The surface pollution of insulators used is also becoming more and more serious. The pollution on the surface of insulators seriously affects its electrical characteristics, and pollution flashover accidents occur, endangering the operation safety of the power grid. Pollution, according to the statistics of the power operation department, pollution flashover accidents of power transmission and tran...
