Natural environment simulator capable of producing fog by ultrasonic wave

Abstract

The invention relates to a natural environment simulator capable of producing fog by ultrasonic wave, belonging to the technical field of high-voltage line insulator performance testing equipment. The natural environment simulator comprises an artificial fog chamber; a wall feed-through sleeve is arranged at one side of the artificial fog chamber in a matching way; the bottom of the artificial fog chamber is provided with an assembling box in a matching way; the assembling box is internally provided with a fog generator and a fan in a matching way; the fog generator and the fan are connected with an external power line; the external power line is used for supplying power; a hook is arranged on the top of the artificial fog chamber in a matching way, and is used for fixing an insulator to be tested; and the fog generator is an ultrasonic fog generator. As the ultrasonic fog generator and the fan are used together, the fog inlet quantity of the artificial fog chamber can be effectively controlled, and the natural environment needed by a laboratory can be simulated; furthermore, the external screw-type wall feed-through sleeve is arranged at one side of the artificial fog chamber in a matching way, so that the creepage distance can be prolonged, the current is prevented from being in ground connection along a barrel wall, and the personal safety of workers can be improved; and the natural environment simulator is simple in structure, small in size, strong in operability, good in simulation fidelity and easy to move, and can be popularized, applied and implemented.

Description

technical field [0001] The invention belongs to the technical field of performance testing equipment for high-voltage line insulators, and in particular relates to a natural environment simulation device using ultrasonic waves to generate fog. Background technique [0002] Fog generating device is a device assembled to simulate insulators in natural environments such as fogging and light rain that are prone to flashover during insulator performance testing. In order to quickly fill the entire laboratory with water mist, air compressor technology is generally used. Compressed gas and water are mixed and ejected from the pipeline to form mist water. Since the water is formed into mist by impact, there are many problems. In order to avoid the gas-water mixture from directly washing the surface of the insulator, it is necessary to properly open the nozzle of the air compressor Keep the distance from the suspension point of the insulator at more than 1.5 meters. Considering that...

Problems solved by technology

[0003] Since the fog production mechanism is different from the natural fog formation principle, in order to distribute water vapor evenly to the upper and lower surfaces of the insulator, for the detection of insulators of different sizes and models, it is necessary to re-adjust the position of the air compressor so that the water vapor can diffuse to the upper and lower surfaces of the insulator , making the dirt wet, thus increasing the cumbersomeness of the test
