Artificial simulated climate chamber test device capable of forming multiple icing types

Abstract

The invention relates to an artificial simulated climate chamber test device capable of forming multiple icing types. The device comprises an artificial climate chamber. An outer side of the artificial climate chamber is provided with an icing water tank and an air compressor, and is internally connected with icing water atomizer sets and an insulator chain which are correspondingly arranged. The icing water tank is connected with the icing water atomizer sets through a water pipe. The water pipe is connected with a water pump, a water pressure gauge and an icing water valve. The air compressor is connected with the icing water atomizer sets through a gas pipe. The gas pipe is connected with a gas pressure adjusting valve, a gas pressure gauge and an icing gas valve. The device provided by the invention has the advantages that the device is simple to use and operate and convenient to operate and maintain; by adjusting the pressure of icing water and icing gas, multiple icing types of glaze, rime, mixed rime and wet snow can be achieved on the surface of a test object; and the power consumption of refrigeration equipment of an icing test system can be effectively reduced, the economical efficiency of the icing test can be improved, and a foundation is laid for directly applying the icing test result to the deicing design and the ice-melting work of power transmission and transformation equipment in the heavy ice area.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to an artificially simulated climate chamber test device capable of forming various types of icing. Background technique [0002] The icing disaster of outdoor power transmission and transformation equipment seriously threatens the safe operation of the power system. In recent years, in order to study the icing growth mechanism of power transmission and transformation equipment and the impact of icing on the external insulation of power transmission and transformation equipment, universities and scientific research institutions at home and abroad have established their own artificial climate simulation laboratories and carried out a large number of transmission wires. , Icing, melting and ice flash experiments on insulators and bushings. When the above experiments are carried out in the artificial climate chamber, in order to make the experimental results accurate an...

Problems solved by technology

However, due to the limited power of the refrigeration equipment of the icing test system in the existing artificial climate chambers at home and abroad, the ambient temperature of the climate chamber can only drop to about -5°C, so only a single type of rime icing can be formed. Natural observations show that: When the particle size of ice-coated water is 50-100 μm, the ambient temperature for forming rime is -4~0°C, the temperature for mixed rime is -8~-4°C, the temperature for rime is -10~-8°C, wet snow The tempera
