Description

Technical Field

[0001] The invention belongs to the technical field of high and low voltage switch cabinets, and in particular relates to a high-safety high and low voltage switch cabinet with an intelligent adjustment function. Background Art

[0002] High and low voltage switchgear is a type of equipment that connects high or low voltage cables. The external line first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. According to the different connection end voltages, it can be divided into: AC low voltage distribution cabinet, high voltage capacitor distribution cabinet, high voltage switch cabinet, etc.

[0003] Currently, the common high and low voltage switchgear is mainly composed of a cabinet body and protective devices such as switches and circuit breakers. When high and low voltage switchgear is in use, especially the distribution cabinet used in dangerous working environments with conductive dust or flammable and explosive gases, in order to ensure safety, enclosed switchgear or explosion-proof switchgear is generally used.

[0004] During the use of existing high and low voltage switch cabinets, the electrical components inside the cabinets are prone to generate a large amount of heat during long-term operation. In order to reduce the adverse effects of heat on the service life and safety of use of electrical components, exhaust fans are usually installed or the high and low voltage switch cabinets are placed in an air-conditioned room. The effect of cooling the high and low voltage switch cabinets by exhaust fans is poor, and it is easy for external dust to enter the high and low voltage switch cabinets. When the high and low voltage switch cabinets are placed in an air-conditioned room, the high and low voltage switch cabinets are easily affected by the air-conditioned room and water vapor adhesion occurs.

[0005] Therefore, neither the exhaust fan nor the air-conditioning room can perform the function of intelligent temperature regulation for the high and low voltage switch cabinets, and the effect of heat dissipation protection for the high and low voltage switch cabinets is poor, making the high and low voltage switch cabinets easily affected by the internal temperature during use, resulting in damage to electrical components or even explosion, reducing the safety of the use of the high and low voltage switch cabinets.

[0006] Therefore, in view of the above technical problems, it is necessary to provide a high-safety high and low voltage switchgear with intelligent adjustment function. Summary of the invention

The stirring blade 407 rotates along with the rotation of the rotating shaft 405 to mix and stir the cooling liquid in the liquid storage box 215, thereby improving the effect of strong cooling of the cooling liquid in the liquid storage box 215.

[0089] When in use, the temperature in the switch cabinet body 1 is detected by the temperature sensor 208. When the temperature sensor 208 detects that the temperature in the switch cabinet body 1 is too high, the operation of the air extraction pump 202 is controlled to generate negative pressure in the air extraction pipe 203. The high-temperature gas in the switch cabinet body 1 is extracted through the cooperation between the air extraction connecting pipe 204 and the air extraction pipe 203. The extracted high-temperature gas is spirally transported to the cooling purification box 205 under the action of the diffusion conduction pipe 209 and the spiral guide plate 210.

[0090] The cooling liquid in the liquid storage box 215 is extracted by controlling the operation of the boost extraction pump 213, and the extracted cooling liquid is transported to the cooling fins 206 under the action of the liquid delivery pipe 214, the delivery pipe 212 and the connecting pipe 211, and is cooled by the high-temperature gas spirally transported by the multiple groups of cooling fins 206 and the diffuser conduction pipe 209;

[0091] Subsequently, the cooling liquid transported in the spray pipe 218 is sprayed by multiple groups of cooling nozzles 207, and the gas cooled by the cooling fins 206 is sprayed and dust-purified. The sprayed cooling liquid is transported to the liquid collecting tank 225 under the filtering effect of the limiting filter plate 224, and the used cooling liquid is collected by the liquid collecting tank 225;

[0092] At the same time, the cooling liquid in the delivery pipe 212 sprays the cooling liquid toward the packing filter layer 223 under the action of the guide connecting pipe 219 and the nozzle guide pipe 220, and the cooling liquid forms a liquid film on the surface of the packing filter layer 223. The gas after spraying and purification is further cooled and purified under the action of the packing filter layer 223 and the surface liquid film.

[0093] The cooled and purified gas is transported to the centrifugal drying box 301 under the action of the drying conduit 302. The support shaft 305 in the centrifugal drying box 301 rotates under the action of the airflow in the drying conduit 302. The rotation of the support shaft 305 drives the drying molecular sieve 307 to rotate. The rotation of the drying molecular sieve 307 centrifugally dries the gas in the centrifugal drying box 301. At the same time, the activated carbon adsorption net 308 and the polymer water absorption layer 309 cooperate with each other to assist in drying the gas in the centrifugal drying box 301. The dried gas is then transported to the centrifugal drying box 301. The gas is transported to the switch cabinet body 1 by the action of the gas pipe 303 and the heat dissipation nozzle 304. The cooling, purified and dried gas is transported by the heat dissipation nozzle 304 to provide heat dissipation protection for the electrical components in the switch cabinet body 1. In addition, since the exhaust connection pipe 204 is in an exhaust state and the heat dissipation nozzle 304 is in an exhaust state, the heat dissipation nozzle 304 cooperates with the exhaust connection pipe 204 to form a protective gas film on the surface of the electrical components in the switch cabinet body 1. The protective gas film provides heat dissipation and dust prevention protection for the electrical components in the switch cabinet body 1.

[0094] In addition, when the temperature sensor 208 still detects that the temperature inside the switch cabinet body 1 continues to rise, the operation of the conducting pipe 402 is controlled to transport the strong refrigerant stored in the sealed storage tank 401 to the liquid storage box 215. During the transportation in the conducting pipe 402, the strong refrigerant absorbs heat and sublimates under the influence of the temperature of the cooling liquid in the liquid storage box 215. The cooling liquid in the liquid storage box 215 is strongly cooled by the sublimation of the strong refrigerant, thereby improving the effect of cooling the high-temperature gas in the cooling purification box 205 by the cooling liquid. At the same time, due to the sublimation of the strong refrigerant in the liquid storage box 215, the air pressure in the liquid storage box 215 is enhanced. The enhanced air pressure in the liquid storage box 215 makes the atomization effect of the cooling liquid sprayed by the cooling nozzle 207 and the liquefied membrane nozzle 221 better, further improving the effect of cooling the gas in the cooling purification box 205.
