The stability and reliability effect that use environment residing for KYN28A-12 10KV switch cubicles is used for are serious, In wet environment or because the reason such as condensation, insulating properties reduction causes flashover or even occurs short circuit accident.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of KYN28-12 10KV switch cubicles, and it utilizes air stream The steam in equipment is taken away, stabilization of equipment performance and reliability is improved.

To reach above-mentioned purpose, the technical solution of the utility model is：A kind of KYN28-12 10KV switch cubicles, including cabinet Body, is separated out bus-bar room, cable vault, relay control room, switch gear room and access path, described in the cabinet inner route clapboard Switch gear room includes air compressor, the air pressure built with handcart, in addition to air dehumidifier, the air dehumidifier Contracting machine connects air accumulator, and air accumulator bottom is provided with air inlet pipe, and the air inlet pipe each leads into bus-bar room and switch gear room；The bus Room and the switch gear room are also equipped with escape pipe, and the escape pipe, which is passed through, is provided with the of outlet on a buffer tank, the buffer tank One one-way cock.

Further improve, the second one-way cock of air inlet is housed in the air inlet pipe.

Further improve, temperature sensor and humidity sensor are installed on the handcart.

Further improve, box is removed equipped with vapor between the air compressor and the air accumulator, steamed in the water Gas removes box built with water vapor adsorption agent.

Further improve, the vapor is removed to be connected between box and the air accumulator by pipeline, in the pipeline Equipped with resistive heater.

Further improve, the buffer tank is embedded in the top of the cabinet.

Further improve, the air compressor and the air accumulator are installed in the top of the cabinet.

The air compression in environment is passed through in air accumulator, the air accumulator by air compressor in the utility model Air is passed through bus-bar room and switch gear room by air inlet pipe, and due to being constantly passed through air into equipment, air is flowed into from escape pipe Buffer tank is discharged into air again, to be formed air-flow because air is flowed into and out in equipment and is taken away vapor in equipment, reduction Air humidity in equipment, prevents condensation, prevents flashover or even occurs the generation of short circuit accident, improves the reliability of equipment and steady It is qualitative.

Brief description of the drawings

Fig. 1 is the utility model structural representation.

Embodiment

The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.

Shown in Fig. 1, a kind of KYN28-12 10KV switch cubicles, including cabinet 100, separate in the inner route clapboard of cabinet 100 Go out bus-bar room 110, cable vault 120, relay control room 130, switch gear room 140 and access path 150, in the switch gear room 140 Built with handcart 200, in addition to air dehumidifier 3, the air dehumidifier 3 includes air compressor 31, the air Compressor 31 connects air accumulator 32, and the bottom of air accumulator 32 is provided with air inlet pipe 33, and the air inlet pipe 33 each leads into the He of bus-bar room 110 Switch gear room 140；The bus-bar room 110 and the switch gear room 140 are also equipped with escape pipe 34, and the escape pipe 34 is passed through a buffer tank 35, the first one-way cock 36 of outlet is installed on the buffer tank 35.Air in environment is compressed logical by air compressor 31 The air entered in air accumulator 32, the air accumulator 32 is passed through bus-bar room 110 and switch gear room 140 by air inlet pipe 33, due to continuous Air is passed through into equipment, air flows into buffer tank 35 from air inlet pipe 33 and is discharged into again in air, because air enters in equipment Enter and flow out to form air-flow and take away air humidity in vapor in equipment, reduction equipment, prevent condensation, prevent flashover even Occur the generation of short circuit accident, improve the reliability and stability of equipment.

In the air inlet pipe 33 be equipped with air inlet the second one-way cock 37, prevent cabinet 100 from exploding, generation it is powerful Blast flow to air compressor 31.

Temperature sensor 4 and humidity sensor 5, the temperature sensor 4 and humidity sensor are installed on the handcart 200 The temperature and humidity that device 5 is used in pilot switch room 140, so as to adjust the flow velocity of air-flow, keeps suitable air-flow；Prevent from being passed through The excess air wasting of resources is either passed through that gas flow is less effectively to be taken away the vapor in equipment.

Box 38 is removed equipped with vapor between the air compressor 31 and the air accumulator 32, is removed in the vapor Air by air compressor 31 is passed through the water in vapor removal box 38, air by box 38 built with water vapor adsorption agent Molecule is absorbed after being in contact with water vapor adsorption agent by water vapor adsorption agent, and the air of relatively dry is passed through in equipment, due to setting The concentration of vapor of the water vapor concentration compared with the dry air being passed through of standby interior air is high, due to the concentration gradient of vapor, The concentration of vapor is reduced and is entrained by the flow of air rapidly in equipment, and the effect of drying to equipment is notable.

The vapor is removed to be connected between box 38 and the air accumulator 32 by pipeline, in the pipeline built with heating Resistance wire, resistive heater is heated to air, and hot-air, which is passed through device interior, prevents the water vapor condensation in equipment, it is to avoid solidifying Dew.

The buffer tank 35 is embedded in the top of the cabinet 100, and buffer tank 35 is connected with air inlet pipe 33, the jail of buffer tank 35 Guan County is on the solid, once being exploded in solid, the blast of generation will be from the entrance buffer tank 35 of air inlet pipe 33 and from first Device for transferring in one-way cock 36.

The air compressor 31 and the air accumulator 32 are arranged on the top of the cabinet 100, save space, and reduction is accounted for Ground area, beneficial to equipment control.

It the above is only one preferred embodiment of the utility model, those skilled in the art makees equivalent by claim Change the protection domain for both falling within this case.
