Description

Combined type electric power equipment dehumidification drying device

The utility model relates to a kind of combined type electric power equipment dehumidification drying device, relates in particular to the dehumidification drying device of being made up of air compressor, cold and hot switch room, condensation chamber, hothouse.

Understand the situation of making moist in the power equipment use.As the outdoor high-voltage oil-minimum breaker, often because caulking gum is loose or make moist in maintenance process, the moisture content of breaker insulating oil own exceeds standard sometimes.By the electrical equipment preventive test rules, after the outdoor high-voltage oil-minimum breaker makes moist, in use can, the insulation flashover accident takes place, cause large-area power-cuts, prestige association's life and device security.Therefore, after the outdoor high-voltage oil-minimum breaker makes moist, the drying of must making moist.At present, the common method to the removal moisture drying of outdoor high-voltage oil-minimum breaker has two kinds: a kind of is that the insulating oil of breaker has been put, and the breaker lifting is disintegrated, and lifting arm, insulating materials etc. is put into the drying baker heating, drying; The 2nd, in breaker, use insulating oil heat cycles drying with vacuum oil-filter.Though more than two kinds of methods can both carry out the dehumidifying drying to the outdoor high-voltage oil-minimum breaker.But all there is certain defective, as first method owing to need the breaker lifting, install, need to drop into a large amount of human and material resources, and construction period needs 2-3 days, though second method does not need breaker is disintegrated, but insulating oil is heated and wears out easily in dry run, and the vacuum oil-filter heating tube burns out the equipment heaviness easily.

The purpose of this utility model provides a kind of combined type electric power equipment dehumidification drying device, to overcome above-mentioned shortcoming.

For achieving the above object, combined type electric power equipment dehumidification drying device of the present utility model is made up of air compressor, cold and hot switch room, condensation chamber and hothouse.Be provided with cold and hot exchange pipe in the cold and hot switch room, be provided with condenser pipe in the condensation chamber, be provided with discolour silica gel and electric heating tube in the hothouse.Gas circuit communicates between air compressor, cold and hot switch room, condensation chamber and the hothouse.

Adopt such scheme, owing to air compressor moisture is taken out of with air, through cold and hot switch room, condensation chamber, hothouse, moisture content is removed, and reaches the purpose of removal moisture drying.That this device has is simple in structure, easy and simple to handle, drying time short, effective advantage.

Below in conjunction with drawings and embodiments the utility model combined type electric power equipment dehumidification drying device is described in further detail.

Fig. 1 is the utility model combined type electric power equipment dehumidification drying device cutaway view.

Fig. 1 is the utility model combined type electric power equipment dehumidification drying device enforcement figure.

Combined type electric power equipment dehumidification drying device shown in Figure 1 is made up of air compressor 1, cold and hot switch room 2, condensation chamber 3 and hothouse 4.Air compressor 1 is connected to the heatproof rubber tube 5 of giving vent to anger, and air compressor 1 links to each other with cold and hot switch room 2 usefulness heatproof rubber tubes 6, and heatproof rubber tube 6 is connected on the intake valve 7 of cold and hot switch room 2.

Cold and hot exchange pipe 8 is arranged in the cold and hot switch room 2 shown in Figure 1, and there is the water pot 9 of collection the below.Cold and hot switch room 2 links together with condensation chamber 3 usefulness steel plates 10, and steel plate 10 two ends offer condensation chamber hot blast air inlet 11 and condensation chamber cold wind gas outlet 12 respectively.

In the condensation chamber 3 shown in Figure 1 condenser pipe 13 is arranged, freezing liquid 14 is housed in the condenser pipe 13, there is seal capsule 15 freezing liquid 14 tops, and seal capsule 15 usefulness screw 16a, 16b fix.For freezing liquid 14 is recycled, electrodynamic pump 17 is housed at condenser pipe 13 middle parts in condenser pipe 13.Condensation chamber 3 tops also have fin 18, and electric fan 19 is equipped with on fin 18 limits.Condensation chamber 3 belows are provided with collects water pot 20.

Cold and hot switch room 2 shown in Figure 1 links together with hothouse 4 usefulness steel pipes 21.Discolour silica gel 22 and electric heating tube 23 are housed in the hothouse 4, separate with steel plate 24 in the middle of discolour silica gel 22 and the electric heating tube 23, passage 25 is left in steel plate 24 belows.Discolour silica gel 22 is arranged in the steel plate 26 with holes, and discolour silica gel 22 is packed into from blind nut 27, takes out from blind nut 28, for observing discolour silica gel 22 water sucting degrees, at hothouse 4 a closed observation window 29 is set.Hothouse 4 tops also are respectively equipped with Pressure gauge 30, visit quick 31 and air bleeding valve 32.Air bleeding valve 32 is connected with air inlet heatproof rubber tube 33.

Air compressor 1 shown in Figure 1, cold and hot switch room 2, condensation chamber 3 and a plurality of screws of hothouse 4 usefulness are fixed on the steel plate frame 34, are connected as a single entity.

Describe below by the outdoor high-voltage oil-minimum breaker being carried out the embodiment of removal moisture drying the utility model combined type electric power equipment dehumidification drying device.Shown in Figure 2 outdoor high-voltage oil-minimum breaker 35 insulating oils have all been put, opened breaker delthyrial cavity seal cover,, put into the insulated porcelain sleeve 36,37 of breaker 35 respectively the air inlet heatproof rubber tube 33 and the heatproof rubber tube 5 of giving vent to anger.Start air compressor 1, connect electrodynamic pump 17 electric fans 19, electric heating tube 23, hot blast is extracted out from breaker insulated porcelain sleeve 37, can take moisture content out of in the hot blast, through air compressor 1 hot blast is compressed into cold and hot switch room 2, after the cold and hot replace tubes 8 of process carries out cold and hot exchange, enter condensation chamber 3 by crossing condensation chamber hot gas air inlet 11, hot blast becomes cold air after supercooling, have supersaturation ponding to flow into simultaneously and collect in the water pot 20.Cold air enters cold and hot switch room 2 to carry out cold and hot exchange and becomes hot blast again from condensation chamber cold wind gas outlet 12, and hot blast enters hothouse 4 by steel pipe 21.The discolour silica gel 22 that moisture content in the hot blast is dried in the chamber 4 absorbs, and is to guarantee that discolour silica gel 22 fully absorbs moisture content, and the pressure in the hothouse 4 needs greater than 1 standard atmospheric pressure.After absorbing moisture content through discolour silica gel 23, hot blast is heated by electric heating tube 23 by passage 25 again, and the hot blast after the heating is pressed into insulated porcelain sleeve 36 in the breaker 35 again by air inlet temperature resistant rubber hose 33.By heat-wind circulate drying, effectively the moisture in the insulated porcelain sleeve 36,37 is removed like this, whole process only needs about half an hour.

As a same reason, the utility model combined type electric power equipment removes warm drying device also applicable to other power equipment removal moisture drying, also can be applicable to the removal moisture drying of other industry.
