The main function of high and low voltage switchgear is to open and close, control and protect electrical equipment during power generation, transmission, distribution and energy conversion in the power system. The components in the switchgear mainly include circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protective devices.

[0003] The prior art discloses some invention patents in the technical field of high and low voltage switch cabinets, among which the invention patent with publication number CN118825796A discloses an outdoor high and low voltage moisture-proof switch cabinet, including a cabinet body, a cabinet door, a heat dissipation fan and an air inlet frame. The cabinet body includes an outer shell and an inner shell, and a heat dissipation cavity is arranged between the outer shell and the inner shell. The heat dissipation cavity is divided into an upper heat dissipation cavity and a lower heat dissipation cavity. Connecting pipes are installed in the upper heat dissipation cavity and the lower heat dissipation cavity. A heat dissipation pipe is fixed on one side of the outer shell, and also includes: a moisture-proof mechanism, which includes a water absorbing member, a drying component and a fixing component. In the technical solution, an outdoor high and low voltage moisture-proof switch cabinet, the heat dissipation fan, the upper heat dissipation cavity, the connecting pipe, the drying mechanism, the lower heat dissipation cavity, the heat dissipation pipe and the air inlet frame together constitute an airflow circulation system of the switch cabinet, which can not only realize the heat dissipation function of the switch cabinet and reduce the temperature inside the switch cabinet, but also dry the air entering the switch cabinet to realize the moisture-proof function of the switch cabinet and ensure that the electrical equipment in the switch cabinet always maintains a good operating state;

[0004] There are still some shortcomings in the application of the above technical solutions. Most distribution rooms are built in basements. The environment of the basement is relatively closed and the ventilation conditions are poor. As the power equipment in the cabinet generates heat and causes temperature changes, coupled with changes in ambient temperature, water vapor will condense into condensation when it encounters a relatively cold cabinet. In addition, the interior of the distribution cabinet is relatively sealed and the air flow is poor, which can easily lead to green hair, carbon ash, mildew and other phenomena on the moving and static contacts and busbars. In severe cases, it may also lead to a decrease in insulation strength and cause discharge problems.

An impeller is installed in the port of the transfer tube B. The outer surface of the transfer tube B corresponds to the hybrid wheel installed in the thermostatic box. The other end of the transfer tube is connected to an umbrella-shaped head, and a diverter hole is opened on the umbrella-shaped head.

[0028] A method for using a self-heating energy-saving high and low voltage switch cabinet, the method comprising:

[0029] As the temperature changes due to the heating of the electrical equipment inside the switch cabinet body, the temperature of the upper inner side of the switch cabinet body accumulates. When encountering a low temperature environment, the water vapor condenses into condensation when encountering the relatively cold outer shell of the switch cabinet body, and the hydraulic cylinder is controlled to perform telescopic movement. The hydraulic cylinder performs extension movement and pushes the U-shaped frame upward through the piston rod. During this process, the corners of the teeth of the tooth piece B abut against the inner wall of the U-shaped frame, and the other side cannot rotate in the adapter seat through the adapter shaft. The U-shaped frame meshes with the driven gear through multiple tooth pieces B and drives the driven gear to rotate. The driven gear drives the transfer tube A through the docking box, and the other end of the transfer tube A drives the condensation removal tube to rotate in one direction through the compensation sleeve. Since the upper inner side of the switch cabinet body is a directional structure, the distance between the condensation removal tube and the top wall and front wall of the switch cabinet body will change during the rotation process. The distance is reduced, and the top wall or front wall of the switch cabinet body pushes the condensation removal tube through the limit roller, and the condensation removal tube slides in the compensation sleeve and pulls the compensation spring to release. The condensation removal tube is elastically deformed, the distance is reduced, and the thrust of the top wall or front wall of the switch cabinet body on the condensation removal tube through the limit roller is reduced. The compensation spring gradually restores the elastic deformation and pushes the condensation removal tube in the opposite direction. With the cooperation of the compensation spring and the limit roller, the condensation removal tube can maintain a relative distance from the top wall, front wall and rear wall of the switch cabinet body, ensuring that the condensation suction hole on the condensation removal tube is always close to the top wall, front wall and rear wall of the switch cabinet body. The hydraulic cylinder is controlled to retract. The teeth of the tooth piece B are subjected to the resistance from the driven gear, and it rotates in the adapter seat through the adapter shaft, and twists the adapter spring to cause elastic deformation. At this time, the teeth of the tooth piece A are in contact with the inner wall of the U-shaped frame, and the other side cannot be rotated in the adapter seat through the adapter shaft. The U-shaped frame meshes with the driven gear through multiple tooth pieces A, and drives the driven gear to rotate in the opposite direction. With the structural characteristics of the condensation removal tube, the condensation removal tube is fully swept across the upper inner side of the switch cabinet body.

[0030] When the hydraulic cylinder drives the piston rod to perform reciprocating lifting and lowering motion, the piston rod also drives the piston member to move in the piston tank, and the piston disc drives the sealing gasket A downward, and the pressure at the corresponding sealing gasket A in the piston tank is reduced. At this time, the one-way valve A1 on the condensation suction pipe A opens, and the condensation suction pipe A applies negative pressure suction to the docking box. The docking box applies negative pressure suction to the condensation removal pipe through the transfer pipe A and the telescopic pipe, and the condensation removal pipe absorbs the condensation condensed on the upper inner side of the switch cabinet body through multiple condensation suction holes to prevent the condensation volume from increasing and dripping, causing a short circuit in the electrical equipment inside the switch cabinet body. The piston disc drives the sealing gasket B upward, and the pressure at the corresponding sealing gasket B in the piston tank is reduced. At this time, the one-way valve B1 on the condensation suction pipe B opens, and the condensation suction pipe B applies negative pressure suction to the docking box, thereby continuously providing negative pressure suction to the condensation removal pipe;

[0031] The corresponding condensation suction pipe A and condensation suction pipe B on the piston tank are connected with condensation discharge pipe A and condensation discharge pipe B respectively. When the piston seat drives the sealing gasket A upward, the pressure at the corresponding sealing gasket A in the piston tank increases, and the one-way valve A2 on the condensation discharge pipe A opens. When the piston seat drives the sealing gasket B downward, the pressure at the corresponding sealing gasket B in the piston tank increases, and the one-way valve B2 on the condensation discharge pipe B opens. The condensation discharged through the condensation discharge pipe A and the condensation discharge pipe B flows into the constant temperature box. With the discharge of condensation on the upper inner side of the switch cabinet body, the air pressure on the upper inner side of the switch cabinet body decreases, and the air at the bottom of the switch cabinet body enters the switch cabinet body through the transfer pipe B and the air outlet. The air entering the transfer pipe B will drive the impeller to rotate, and the impeller drives the hybrid wheel and the umbrella head to rotate through the transfer pipe B. The rotation of the hybrid wheel will accelerate the flow rate of condensation in the insulation box, thereby cooling the air flowing through the transfer pipe B.

[0032] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0033] 1. In the present invention, negative pressure suction can be continuously provided to the condensation removal pipe, which effectively solves the problem of condensation on the upper inner side of the switch cabinet body. The interior of the switch cabinet body is relatively sealed and the air flow is poor, thereby avoiding the occurrence of green hair, carbon ash, mildew and the like on the moving and static contacts and busbars, resulting in a decrease in insulation strength and causing discharge.

[0034] 2. In the present invention, the teeth of the toothed member B are subjected to the resistance from the driven gear, and it rotates in the adapter seat through the adapter shaft, and twists the adapter spring to cause elastic deformation. At this time, the teeth of the toothed member A are abutted against the inner wall of the U-shaped frame with its corners, and the other side cannot be rotated in the adapter seat through the adapter shaft. The U-shaped frame is meshed with the driven gear through multiple teeth A, and drives the driven gear to rotate in the opposite direction. In combination with the structural characteristics of the condensation removal pipe, the condensation removal pipe can be fully swept across the upper inner side of the switch cabinet body.

[0035] 3. In the present invention, the air at the bottom of the switch cabinet body enters the switch cabinet body through the transfer tube B and the air outlet. The air entering the transfer tube B will drive the impeller to rotate. The impeller drives the hybrid wheel and the umbrella head to rotate through the transfer tube B. The rotation of the hybrid wheel will accelerate the flow rate of condensation in the insulation box, thereby cooling the air flowing through the transfer tube B. The rotation of the umbrella head and the diversion holes on its surface can play a good diversion role for the air flowing into the switch cabinet body, avoiding the situation where the air flow rate flowing into the switch cabinet body is faster when the working frequency of the control hydraulic cylinder increases, thereby affecting the stability of the power equipment joint. The air diversion is also conducive to the rapid diffusion of the cooled air in the switch cabinet body, thereby improving the air cooling effect inside the switch cabinet body.

[0059] A method for using a self-heating energy-saving high and low voltage switch cabinet, the method comprising:

[0060] As the temperature changes due to the heating of the electrical equipment inside the switch cabinet body 1, the temperature of the upper inner part of the switch cabinet body 1 accumulates. When encountering a low temperature environment, the water vapor condenses into condensation when encountering the relatively cold outer shell of the switch cabinet body 1, and the hydraulic cylinder 407 is controlled to perform telescopic movement. The hydraulic cylinder 407 performs the extension movement and pushes the U-shaped frame 403 upward through the piston rod 406. During this process, the corner of the tooth 4041 of the tooth piece B405 abuts against the inner wall of the U-shaped frame 403, and the other side cannot rotate in the adapter seat 4043 through the adapter shaft 4042. The U-shaped frame 403 meshes with the driven gear 402 through multiple tooth pieces B405 and drives the driven gear The wheel 402 rotates, and the driven gear 402 drives the transfer tube A302 through the docking box 401. The other end of the transfer tube A302 drives the condensation removal tube 3041 to rotate in one direction through the compensation sleeve 303. Since the upper inner part of the switch cabinet body 1 is a directional structure, the distance between the condensation removal tube 3041 and the top wall and the front wall of the switch cabinet body 1 will change during the rotation. The distance is reduced, and the top wall or the front wall of the switch cabinet body 1 pushes the condensation removal tube 3041 through the limiting roller 305. The condensation removal tube 3041 slides in the compensation sleeve 303 and pulls the compensation spring 3042 to elastically deform. As the distance decreases, the thrust of the top wall or front wall of the switch cabinet body 1 on the condensation removal pipe 3041 through the limiting roller 305 decreases, and the compensation spring 3042 gradually recovers its elastic deformation and pushes the condensation removal pipe 3041 in the opposite direction. With the cooperation of the compensation spring 3042 and the limiting roller 305, the condensation removal pipe 3041 can maintain a relative distance from the top wall, front wall and rear wall of the switch cabinet body 1, ensuring that the condensation suction hole 3044 on the condensation removal pipe 3041 is always close to the top wall, front wall and rear wall of the switch cabinet body 1, and the hydraulic cylinder 407 is controlled to retract, and the teeth 4041 of the tooth piece B405 are moved. Under the resistance from the driven gear 402, it rotates in the adapter seat 4043 through the adapter shaft 4042, and twists the adapter spring 4044 to make it elastically deformed. At this time, the corner of the tooth 4041 of the tooth piece A404 abuts against the inner wall of the U-shaped frame 403, and the other side cannot rotate in the adapter seat 4043 through the adapter shaft 4042. The U-shaped frame 403 meshes with the driven gear 402 through multiple tooth pieces A404, and drives the driven gear 402 to rotate in the opposite direction. In combination with the structural characteristics of the condensation removal pipe 3041, the condensation removal pipe 3041 is fully swept across the upper inner side of the switch cabinet body 1;

[0061] When the hydraulic cylinder 407 drives the piston rod 406 to perform reciprocating lifting motion, the piston rod 406 also drives the piston member 501 to move in the piston tank 502, and the piston plate drives the sealing gasket A5012 downward, and the pressure at the corresponding sealing gasket A5012 in the piston tank 502 decreases. At this time, the one-way valve A1 on the condensation suction pipe A504 opens, and the condensation suction pipe A504 applies negative pressure suction force to the docking box 401. The docking box 401 applies negative pressure suction force to the condensation removal pipe 3041 through the transfer pipe A302 and the telescopic pipe 3043. , and the condensation condensed on the upper inner side of the switch cabinet body 1 is absorbed by the condensation removal pipe 3041 through multiple condensation suction holes 3044 to prevent the condensation volume from increasing and dripping, causing a short circuit in the electrical equipment inside the switch cabinet body 1. The piston disk drives the sealing gasket B5013 upward, and the pressure at the corresponding sealing gasket B5013 in the piston tank 502 decreases. At this time, the one-way valve B1 on the condensation suction pipe B505 is opened, and the condensation suction pipe B505 applies negative pressure suction force to the docking box 401, thereby continuously providing negative pressure suction force to the condensation removal pipe 3041;

When encountering a low temperature environment, the water vapor encounters the relatively cold outer shell of the switch cabinet body (1) and condenses into condensation, controlling the hydraulic cylinder (407) to perform telescopic movement. The hydraulic cylinder (407) performs the extension movement to push the U-shaped frame (403) upward through the piston rod (406). During this process, the teeth (4041) of the toothed member B (405) are abutted against the inner wall of the U-shaped frame (403) at the corners, and the other side cannot be rotated in the adapter seat (4043) through the adapter shaft (4042). The U-shaped frame (403) is meshed with the driven gear (402) through the plurality of toothed members B (405) and drives the driven gear (402) rotates, the driven gear (402) drives the transfer tube A (302) through the docking box (401), and the other end of the transfer tube A (302) drives the condensation removal tube (3041) to rotate in one direction through the compensation sleeve (303). Since the upper inner side of the switch cabinet body (1) is a directional structure, the distance between the condensation removal tube (3041) and the top wall and the front wall of the switch cabinet body (1) will change during the rotation process. The distance is reduced, and the top wall or the front wall of the switch cabinet body (1) pushes the condensation removal tube (3041) through the limiting roller (305). The condensation removal tube (3041) slides in the compensation sleeve (303) and pulls the compensation spring (3042) to elastically deform. The distance between the top wall and the front wall of the switch cabinet body (1) decreases, and the thrust of the top wall or the front wall of the switch cabinet body (1) on the condensation removal pipe (3041) through the limiting roller (305) decreases, and the compensation spring (3042) gradually recovers its elastic deformation and pushes the condensation removal pipe (3041) in the opposite direction.

The hydraulic cylinder (407) is controlled to perform a retracting movement, and the teeth (4041) of the toothed member B (405) are affected. Due to the resistance of the driven gear (402), it rotates in the transfer seat (4043) through the transfer shaft (4042), and twists the transfer spring (4044) to cause it to undergo elastic deformation. At this time, the corners of the teeth (4041) of the tooth piece A (404) abut against the inner wall of the U-shaped frame (403), and the other side cannot rotate in the transfer seat (4043) through the transfer shaft (4042). The U-shaped frame (403) meshes with the driven gear (402) through a plurality of tooth pieces A (404), and drives the driven gear (402) to rotate in the opposite direction, and cooperates with the structural features of the condensation removal pipe (3041) to achieve a comprehensive sweep of the condensation removal pipe (3041) across the upper inner side of the switch cabinet body (1); When the hydraulic cylinder (407) drives the piston rod (406) to perform reciprocating lifting motion, the piston rod (406) also drives the piston member (501) to move in the piston tank (502), and the piston plate drives the sealing gasket A (5012) downward, and the pressure at the corresponding sealing gasket A (5012) in the piston tank (502) decreases. At this time, the one-way valve A1 on the condensation suction pipe A (504) opens, and the condensation suction pipe A (504) applies negative pressure suction force to the docking box (401). The docking box (401) applies negative pressure suction force to the condensation removal pipe (3043) through the transfer pipe A (302) and the telescopic pipe (3043). 41), and the condensation removal pipe (3041) absorbs the condensation condensed on the upper inner side of the switch cabinet body (1) through a plurality of condensation suction holes (3044) to prevent the condensation volume from increasing and dripping, causing a short circuit in the electrical equipment inside the switch cabinet body (1). The piston disk drives the sealing gasket B (5013) upward, and the pressure at the corresponding sealing gasket B (5013) in the piston tank (502) decreases. At this time, the one-way valve B1 on the condensation suction pipe B (505) opens, and the condensation suction pipe B (505) applies negative pressure suction force to the docking box (401), thereby continuously providing negative pressure suction force to the condensation removal pipe (3041); The corresponding condensation suction pipe A (504) and condensation suction pipe B (505) on the piston tank (502) are respectively connected to the condensation discharge pipe A and the condensation discharge pipe B. When the piston seat (5011) drives the sealing gasket A (5012) upward, the pressure at the corresponding sealing gasket A (5012) in the piston tank (502) increases, and the one-way valve A2 on the condensation discharge pipe A opens. When the piston seat (5011) drives the sealing gasket B (5013) downward, the pressure at the corresponding sealing gasket B (5013) in the piston tank (502) increases, and the one-way valve B2 on the condensation discharge pipe B opens, and the condensation discharged through the condensation discharge pipe A and the condensation discharge pipe B flows into the constant temperature In the box (801), as the condensation on the upper inner side of the switch cabinet body (1) is discharged, the air pressure on the upper inner side of the switch cabinet body (1) decreases, and the air at the bottom of the switch cabinet body (1) enters the switch cabinet body (1) through the transfer tube B (8031) and the air outlet (9). The air entering the transfer tube B (8031) drives the impeller (8035) to rotate, and the impeller (8035) drives the hybrid wheel (8034) and the umbrella head (8032) to rotate through the transfer tube B (8031). The rotation of the hybrid wheel (8034) accelerates the flow rate of condensation in the insulation box, thereby cooling the air flowing through the transfer tube B (8031).
