Problems solved by technology

[0007] In traditional experimental research, the influencing factor of the temperature difference between the temperature of the insulator and the dirty laboratory is usually ignored. In fact, the cooling method, the degree of cooling, and the test method will all affect the moisture content of the insulator surface.

Embodiment

[0038] In order to explain the method of use provided by the present invention in more detail, it is specified by setting the ambient temperature required for the insulator test to be 8°C:

[0039] Step 1: Set the set temperature of the coil to -25°C. After running for 30 minutes, the temperature of the heat transfer oil in the coil is about -25±0.3°C; The air is blown upwards, and the fogging humidifier is turned on at the same time to keep the humidity in the haze tank constant, reduce the variables, and measure the temperature in the haze tank through the temperature sensor, and the running time is about 5 minutes;

[0040] Step 2: Turn on the fan around the coil to further cool down the temperature inside the mist tank. The mist humidifier is still turned on. The operating time is about 2 minutes, and the ambient temperature can reach 8°C

[0041] If the temperature required for the test is between 12 and 20°C, step 2 can be omitted to directly meet the test requirements. ...

Abstract

The invention provides an Insulator flashover test temperature control device. The device comprises a haze tank which is used for simulating an insulator environment, a thermostat which is used for controlling the temperature of the haze tank to be constant, and a fogging humidifier which is used for adjusting humidity in the haze tank. The thermostat continuously adjusts the conduction oil temperature in a coil, and then the environment temperature in the haze tank is smoothly controlled, so as to meet the requirement of the test temperature. In addition, the diameter, the height and the number of layers of the coil can be adjusted. The amount of the conduction oil in the coil can be changed, so as to adapt to the environment temperature requirement of artificial mist chambers of different sizes. In addition, the invention further provides the use method of the device.

Description

technical field [0001] The invention relates to the technical field of high-voltage insulator tests, in particular to a temperature control device for insulator flashover tests and an application method thereof. Background technique [0002] With the frequent occurrence of insulator flashover accidents in the power system, the influence of environmental factors and their components on the flashover characteristics of insulators has gradually received attention. Some results have been obtained, and many measures have been taken to prevent the occurrence of pollution flashover of insulators. [0003] When studying the influence of environmental component haze on the flashover characteristics of polluted insulators, Jiang Xingliang and others from Chongqing University developed an artificial haze chamber to simulate the haze environment through ultrasonic foggers and aerosol generators. In order to simulate the smog test conditions, Jiang Xingliang et al. used plexiglass to ma...
