Background technique

The electrical equipment cabinets of substations or factories can be seen everywhere. With the requirements of intelligence, such as some newly added merging units in smart substations, smart terminals are distributed locally in terminal boxes, central control cabinets and operating mechanism boxes. The protection, control and intelligent terminals are directly installed in the armored switchgear. Since the operation of control equipment such as power electronics has high requirements for environmental temperature, humidity, dustproof and shockproof, for a long time, terminal boxes, switchgear and operating The mechanism box has been using open electric heating to prevent condensation and natural or fan forced ventilation to cool down. In fact, it is heating humid air to flow and prevent condensation. It cannot really dehumidify, control temperature and prevent dust at all. Armored switch cabinets are used in the switch room The internal electric heating and the fan work to flow the moisture, and then use the industrial dehumidifier to dehumidify the switch room. The safety requirements of the switch room and outdoor ventilation are explosion-proof and accidental smoke exhaust. In fact, the industrial dehumidifier dehumidifies the switch room and the outside together. The dehumidification method of electrical equipment not only has poor dehumidification effect, but also raises the operating environment temperature of electrical equipment, dust is everywhere in the cabinet, and the inspection found that Cordyceps has become a common phenomenon. The basic requirements for the safe operation of electrical equipment in the future.

Contents of the invention

In order to meet the basic requirements of current power electronics and other electrical equipment on the humidity, temperature and dustproof of the operating environment, the present invention adopts an energy-saving closed-pipe dehumidification and temperature regulator for electrical equipment cabinets for dehumidification, humidity control and dustproofing. Realize the safe and reliable operation of the power grid.

The technical scheme adopted by the present invention to solve the technical problem is: divide the closed rectangular cabinet into sequentially connected wet air distribution chambers, humid air temperature control areas, dehumidification compressor chambers, and dehumidification condensation chambers according to the upper, lower, left, and right directions. , the dry air temperature adjustment area and the dry air temperature adjustment collection chamber, and the cooling water tank is directly below the rectangular closed cabinet. The high-temperature and high-humidity air in the terminal box, switch cabinet, operating mechanism box and armored switch cabinet is dehumidified by each terminal dehumidification device and collected into the wet air main pipe. The wet air main pipe is buried in the grass or cable In the lowest layer of the ditch, the high-temperature and high-humidity or low-temperature and high-humidity air flowing in the wet wind main pipe is cooled or heated to a certain extent. In seasons, the wet wind temperature adjustment area sprays water mist outside the pipe and the fan is forced to cool, and the high-temperature and high-humidity air is further cooled. As the ambient temperature changes, the fan in the wet wind temperature adjustment area and the water mist outside the pipe can be used independently or in combination to control the wet wind. The temperature of the humid air flowing in the pipeline in the temperature adjustment area is adjusted, and the high humidity air enters the dehumidification compressor chamber, and the booster fan in the dehumidification compressor chamber increases the flow speed of the humid air, and at the same time forms a certain dehumidification air negative pressure in the humid air main pipe , the flowing humid air flows through the cooling fins on the compressor to take away the heat of the compressor, preventing the compressor body from overheating and protecting the action. The heated and flowing humid air enters the dehumidification and condensation chamber, and the humid and hot air in the dehumidification and condensation chamber is carried out on the surface of the condensation fins. Heat exchange, condensed water is formed on the surface of the condensing fins, and the condensed water flows into the condensed water collection pan under the action of gravity, and falls into the funnel of the funnel-type large-diameter ball valve through the condensed water discharge pipe. In high temperature seasons, the funnel-type large-diameter ball valve is closed The condensed water is kept in the cooling water collection tank for cooling and spraying water. In the low temperature season, the funnel-type large-diameter ball valve is opened, and the condensed water falls directly to the ground through the funnel-type large-diameter ball valve. Since the condensed water discharge pipe is directly connected to the compressor Body contact, to cool down the compressor and at the same time, the condensate discharge pipe will not freeze in the low temperature season, and the condensate discharge pipe will not freeze. The air dried in the dehumidification condensing chamber flows into the dry air temperature adjustment area. The dry air temperature control area sprays water mist outside the pipe and the fan cools down, and the dry air is cooled. With the change of ambient temperature, the fan in the dry air temperature control area and the water mist outside the pipe can be independently or combined to cool the inside of the pipe in the dry air temperature control area The temperature of the flowing dry air is adjusted. In the low temperature season, the grid-type electric heating that flows into the dry air temperature-adjusting collection chamber adjusts the temperature of the dry air. It is also placed in the grassland buried in the ground or the lowest layer of the cable trench. The dry air can regulate the temperature through the main dry air pipe, and the dry air is sent to Outdoor cabinet dehumidification terminal box, the automatic control detection device on each outdoor cabinet dehumidification terminal box intelligently judges the humidity and temperature of the environment in the electrical equipment cabinet, and starts or stops the drying fan in the outdoor cabinet dehumidification terminal box. In the dehumidification terminal box of the outdoor cabinet, there are only the drying fan to blow the dry air and the dehumidification compressor chamber fan to absorb the humid air, so as to ensure the positive pressure of the dry air in each outdoor cabinet and armored switch cabinet, and realize the dehumidification and conditioning in the electrical equipment cabinet. warm purpose. Water filling anti-overflow pipe of cooling water collection tank is composed of water filling anti-overflow pipe of cooling water collection tank, water filling funnel cover and water filling anti-overflow pipe of cooling water collection tank, water addition funnel and water filling anti-overflow pipe of cooling water collection tank The overflow pipe is connected to the water tank and the cooling water collection tank is filled with water and the anti-overflow pipe is composed of a glass water level gauge. The pipe water floating light plastic ball plug has a certain buoyancy in the cooling water. When the cooling water level drops close to the cooling water collection tank and the water tank is connected to the top, the cooling water collection tank is filled with water and the anti overflow pipe water floating light plastic ball plug Block the cooling water collection tank and add water to the anti-overflow pipe. The water tank is connected to the top to prevent dust and prevent cooling water from evaporating. To achieve the goals of dehumidification, temperature regulation and dust prevention in the electrical equipment cabinet, it is also necessary to seal the original ventilation holes, ventilation windows and cabinet doors of the electrical equipment cabinet and heat-insulate the cabinet body.
