Abstract
A hot air drying high voltage isolation box of the utility model, which belongs to the technical field of power transmission and distribution apparatus, is used for solving the insulating performance problems of the high voltage isolation box. The scheme is the existing high voltage isolation box is provided with a dryer and an air blower, and the body of the high voltage isolation box is provided with an air inlet and an air outlet connected with the dryer and the atmosphere. The utility model changes the air-proof heat drying mode to a hot air flowing heat drying mode. The heating temperature of air can be lowered from the original 120 centi-degrees to 40-60 centi-degrees, which can prevent condensation of moisture, eliminate creepage, and increase the insulating performance of the high voltage isolation box. Since a good deal of electric energy is saved by decreasing the heating-up temperature, the utility model adapts for being equipped and used in facilities such as electric precipitator.
Description
Technical field
The utility model relates to high voltage insulating tank, and especially the high voltage insulating tank in the electric cleaner belongs to the power distribution equipment technical field.
Background technology
Electric cleaner mesohigh insulated case will realize safe and reliable operation, and electric heater unit must be set, and utilizes electrical heating elements heating casing hollow gas, to prevent phenomenons such as short circuit, electrode porcelain vase that water in air part dewfall causes be breakdown.Heating-up temperature is higher than 120 ℃, so that water in air part becomes steam.Existing high voltage insulating tank is a closed container body, and air is in static not flow regime basically in the casing.When humidity in the air is big, dewfall does not appear even reach vapourizing temperature, and but can Yin Gaowen moist and phenomenons such as creepage occur, simultaneously, also there is the problem of contamination by dust, the dry insulating properties of high voltage insulating tank are affected; In addition, be in high temperature heating work state for a long time, its high voltage insulating materials is destroyed easily, and expends a large amount of electric energy.
Summary of the invention
The utility model is used to improve the insulating properties of existing high voltage insulating tank and a kind of heated-air drying formula high voltage insulating tank is provided.
The alleged problem of the utility model realizes with following technical scheme:
A kind of heated-air drying formula high voltage insulating tank, its improvement is, on high voltage insulating tank 20, set up drier 21 and air blast 22, on the casing of high voltage insulating tank, set up inlet and outlet mouth 20-1,20-2, the inlet 21-3 of drier is connected, exports 21-4 and is connected with air inlet 20-1 on the casing with air blast, air inlet, the exhaust outlet on the casing of air blast communicate with atmosphere respectively.
Above-mentioned heated-air drying formula high voltage insulating tank, described drier 21 is made up of housing 21-1, electric heating tube 23, and electric heating tube is intervally arranged in housing.
Above-mentioned heated-air drying formula high voltage insulating tank is set up heat-insulation layer 21-2 on the internal valve of described housing.
Above-mentioned heated-air drying formula high voltage insulating tank, described inlet and outlet mouth 20-1,20-2 are separately positioned on the upper and lower of casing.
The utility model provides a kind of design of setting up drier and air blast and the inlet and outlet mouth being set on existing high voltage insulating tank on the High-Voltage Insulation box body, airtight heat drying mode is become the mobile heat drying mode of hot gas, and the heating-up temperature of gas can be reduced to 40～60 degree by 120 original degree; Because what adopt is the dry gas that flows, so dewfall can not occur, there is not the airtight moist phenomenon of high temperature that causes yet, can effectively eliminate creepage trend and phenomenon, the insulating properties of high voltage insulating tank have greatly been improved, and saved a large amount of electric energy because of the reduction of heating-up temperature, power consumption only is original 1/10.Suit in facilities such as electric cleaner, to install and use.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is drier enlarged elevation figure among Fig. 1;
Fig. 3 is the A-A amplification profile among Fig. 2.
The specific embodiment
Consult accompanying drawing, be provided with electric field A, B in the electric cleaner 24, the utility model is used for electric cleaner, and the quantity that generally needs high voltage insulating tank 20 is 3, respectively the extraction electrode 27 at corresponding A, B electric field two ends.Drier 21 and air blast 22 also are fixed in the top of electric cleaner 24.Drier 21 is made up of housing 21-1, electric heating tube 23, and housing is a metal shell, and the housing internal valve is provided with the heat-insulation layer 21-2 of refractory material.Electric heating tube 23 in twos one group misplace at interval and be arranged in the housing, and be fixed on the loam cake 25.23-1 is the electrode of electric heating tube 23, and 26 is outer cover, and 28 is transformer.The inlet 21-3 of drier 21 is connected, exports 21-4 with the outlet of air blast 22 and then is connected by the air inlet 20-1 of three pipelines with three high voltage insulating tank 20 tops.The dry-heat airs that drying device 21 is heated to 40～60 degree enter High-Voltage Insulation mutually in 20 by the air inlet 20-1 of high voltage insulating tank 20 tops, are discharged by the exhaust outlet 20-2 of its below, form mobile thermal current High-Voltage Insulation mutually in.
