The electric heater is controlled by an automatic temperature controller. The beneficial effects of the utility model are that thoroughly solved "pollution flashover" phenomenon that high voltage power supply system insulator produced when heavy fog weather to guarantee power supply system's normal work, it still has characteristics such as simple structure, with low costs, safe and reliable, easy maintenance, application scope are wide simultaneously.
Description
Technical field
The utility model relates to a kind of hollow type internal electrical hot oil bath anti-" pollution flashover " high-tension insulator of heating.
Background technology
At present, the insulator of high voltage supply system because the insulating coefficient of insulator surface descends, " pollution flashover " phenomenon often occurs when big greasy weather occurring, thereby causes urban electricity supply to break down and electric railway is stopped up.Do not find as yet that by retrieval the insulator inner chamber adopts the heat high-tension insulator of anti-" pollution flashover " of electric heating oil bath.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can thoroughly solve the heat high-tension insulator of anti-" pollution flashover " of " pollution flashover " phenomenon appears in the high voltage supply system insulator when foggy weather hollow type internal electrical hot oil bath.
The technical scheme that its technical problem that solves the utility model adopts: the utility model is made up of hollow type insulator, electric heater, temperature sensor, Automatic Temperature Control; The hollow type insulator encapsulates with base and loam cake respectively, the inner cap that constitutes hollow type insulator cavity bottom surface is fixedlyed connected with base, on upper cover base, loam cake is installed by screw, on loam cake and upper cover base, be provided with the spiracle that is connected, between loam cake and upper cover base, be provided with alignment pin, the bottom of loam cake is the cylinder that Open Side Down and stretches in the hollow type insulator cavity, at cylinder end opening end sealed type breathing device is housed, and transformer oil is housed in the cavity of hollow type insulator; Cover and stretch in temperature sensor and electric heater are separately fixed in the transformer oil, temperature sensor is connected with Automatic Temperature Control by lead with electric heater, is connected in series relay J in the electric heater circuit
1Normally opened contact J
1-1, between loam cake and upper cover base, be provided with cushion rubber, between inner cap and base, be provided with cushion rubber.
Operation principle of the present utility model is as follows:
Electric heater is with the transformer oil heating of hollow type high-tension insulator inside, by the conduction of heat of transformer oil, make the heat transferred insulator, make the insulator surface water evaporates, and remain insulator surface and be in drying regime, so just can prevent the generation of " pollution flashover " effectively.The effect of temperature controller and temperature sensor is that the temperature of high-tension insulator outer surface is controlled all the time and remained on more than 20 ℃.
The beneficial effects of the utility model are can stop the high voltage supply system insulator effectively to produce " pollution flashover " phenomenon when foggy weather, to ensure the operate as normal of electric power system.It can determine the power of heater according to the ambient temperature of different regions, and the temperature of high pressure insulator surface is remained at more than 20 ℃.Simultaneously it also have simple in structure, cost is low, characteristics such as safe and reliable, easy to maintenance, applied widely.
