Description

Technical Field

[0001] The invention relates to the field of installation cabinets, and in particular to an installation cabinet for electric power equipment. Background Art

[0002] The installation cabinet for power equipment is a vital component of the power system. It is mainly used for the conversion, distribution, control and protection of electric energy. With the continuous growth of power demand and the increasing complexity of the power system, the design and manufacturing technology of distribution cabinets are also constantly improving. In terms of design and manufacturing, the installation cabinet for power equipment uses advanced CAD software for three-dimensional design, which organically combines design, database, calculation analysis and processing, improves the design speed and reliability of the product, and reduces the labor intensity of related technical personnel.

[0003] In the prior art, electrical equipment in the installation cabinet generates heat during operation. When the temperature is too high, it is difficult for the staff to find it in time, and the high temperature will accelerate the aging of the insulating materials of the electrical equipment. Therefore, an installation cabinet for power equipment is proposed. Summary of the invention

[0004] The present invention aims to solve the technical problem that in the prior art, electrical equipment installed in a cabinet generates heat during operation. When the temperature is too high, it is difficult for staff to detect it in time, and high temperature accelerates the aging of insulating materials of the electrical equipment. An installation cabinet for power equipment is provided.

[0005] The technical solution adopted by the present invention to solve the technical problem is: an installation cabinet for power equipment, including a cabinet body, a first power equipment, a switch sealing door, an alarm device, a heat dissipation and moisture-proof device, a leakage detection device, and a controller. The cabinet is a rectangular parallelepiped.

[0006] The first power equipment is arranged in the cabinet.

[0007] The switch sealed door is arranged vertically and parallel to the front of the cabinet. The switch sealed door is arranged at the front of the cabinet and is rotatably connected to the front of the cabinet through a hinge. Its rotation axis is arranged vertically, and the side of the switch sealed door away from the hinge is connected to the cabinet through a door lock.

[0008] The alarm device is arranged on the cabinet body for alarm prompting.

[0009] The heat dissipation and moisture-proof device is arranged on the cabinet body, and is used for dissipating heat and moisture-proofing the interior of the cabinet body.

[0010] The leakage detection device is arranged on the cabinet body and is used for performing leakage detection inside the cabinet body.

[0011] The controller is arranged on the side surface of the cabinet, and is electrically connected to the alarm device, the heat dissipation and moisture-proof device, and the leakage detection device.

[0012] When the temperature inside the installation cabinet rises and reaches the set value, the alarm device is automatically triggered, so that the staff can take measures in time before the equipment is damaged. Then the staff turns on the heat dissipation and moisture-proof device through the controller, which not only effectively reduces the temperature of the installation cabinet, but also effectively controls the humidity inside the installation cabinet, thereby ensuring the normal operation of the installation cabinet. When the installation cabinet has a leakage phenomenon, the leakage detection device is started, thereby locking the switch sealing door and the cabinet body, which can prevent the staff from opening the switch sealing door without knowing it and touching the leakage part and getting an electric shock.

[0013] Furthermore, the alarm device includes a cavity, an air inlet, a first conductive plate, two tension springs, an electrical contact, a second conductive plate, a through hole, two adjustment rods, an air outlet, an alarm light, and a battery. The cavity is arranged on the side of the cabinet.

[0014] The air inlet is arranged on the side of the cavity, one end of the air inlet is communicated with the interior of the cabinet, and the other end is communicated with the interior of the cavity.

[0015] The first conductive plate is arranged vertically, perpendicular to the front face of the cabinet. The first conductive plate is arranged in the cavity, and is sealingly and slidingly connected to the inner wall of the cavity. The sliding direction thereof is arranged horizontally, and is parallel to the front face of the cabinet.

[0016] The two extension springs are transversely arranged on the side of the first conductive plate close to the air inlet, one end of the two extension springs is fixedly connected to the side surface of the first conductive plate, and the other end is fixedly connected to the inner side surface of the cavity.

[0017] The electrical contact is arranged on the side of the first conductive plate away from the air inlet and is fixedly connected to the side surface of the first conductive plate.

[0018] The second conductive plate is arranged vertically, perpendicular to the front of the cabinet, and is arranged on the side of the electrical contact away from the first conductive plate. The second conductive plate is slidably connected to the inner wall of the cavity, and its sliding direction is arranged horizontally, parallel to the front of the cabinet.

[0019] The through hole is arranged in the middle of the second conductive plate, the diameter of the through hole is adapted to the diameter of the electrical contact, and corresponds to the electrical contact.

[0020] The two adjusting rods are arranged horizontally and parallel to the front of the cabinet. One end of the two adjusting rods is arranged on the outside of the cabinet, and the other end passes through the side of the cabinet and extends into the cavity. They are located on both sides of the through hole and are rotatably connected to the side surface of the second conductive plate. The rotation axis coincides with its own axis. The two adjusting rods are threadedly connected to the side of the cabinet.

[0021] The air outlet is arranged on the side of the cabinet, one end of the air outlet is communicated with the inside of the cavity, and the other end is communicated with the outside.

[0023] The battery is arranged inside the cabinet, fixedly connected to the inner side surface of the cabinet, and electrically connected to the first conductive plate and the alarm light through a wire.

[0024] When the temperature inside the installation cabinet rises, the air pressure inside the installation cabinet is greater than the external air pressure. At this time, the first conductive plate moves to the left under the push of the air pressure. The movement of the first conductive plate to the left drives the electrical contact to move to the left. The electrical contact moves to the left into the through hole and contacts the second conductive plate. At this time, the electricity in the battery passes through the first conductive plate, the electrical contact, and the second conductive plate in turn, and is finally transmitted to the alarm light. Then the alarm light lights up, thereby promptly reminding the staff to take measures before the equipment is damaged.

[0025] Furthermore, the air outlet and the inner wall of the air inlet are respectively fixedly connected with filter screens.

[0026] By setting a filter, dust can be prevented from entering the cavity.

[0027] Further, it includes two support plates and a rainproof plate, The two support plates are vertically arranged above the cabinet, and the lower ends of the two support plates are fixedly connected to the upper surface of the cabinet.

[0028] The rainproof plate is V-shaped, arranged above the two supporting plates, and fixedly connected to the upper surfaces of the two supporting plates.

[0029] By setting up rainproof boards, rain protection can be effectively carried out.

[0030] Furthermore, the heat dissipation and moisture-proof device includes a heat dissipation box, a vent, an activated carbon filter plate, a refrigeration end of a plurality of refrigerators, a desiccant plate, a motor, a heat dissipation fan, a ventilation pipe, and a heat dissipation port. The heat dissipation box is arranged below the cabinet and is fixedly connected to the lower surface of the cabinet.

[0031] The vent is arranged on the side of the heat dissipation box, one end of the vent is communicated with the outside, and the other end is communicated with the inside of the heat dissipation box.

[0032] The activated carbon filter plate is arranged in the vent and is in the same plane as the outer side surface of the heat dissipation port, and the activated carbon filter plate is fixedly connected to the inner wall of the vent.

The cooling ends of several refrigerators are fixedly connected to the inner side of the heat sink, several refrigerators are electrically connected to the controller, and the heating ends of several refrigerators are outside the cabinet.

[0034] The desiccant plate has a porous structure and is provided with desiccant inside. The desiccant plate is arranged vertically and perpendicular to the front of the heat sink. The desiccant plate is arranged on the side of the cooling end of several refrigerators away from the vent and is fixedly connected to the inner side of the heat sink.

[0035] The motor shaft axis is arranged horizontally and parallel to the front of the heat sink. The motor is arranged on the side of the desiccant plate away from the vent. The motor is fixedly connected to the inner side of the heat sink and electrically connected to the controller.

[0036] The axis of the heat dissipation fan coincides with the axis of the motor shaft, and the heat dissipation fan is sleeved on the motor shaft and fixedly connected to the motor shaft.

[0037] The upper end of the ventilation pipe passes through the top of the heat sink and the bottom of the cabinet in turn, and the lower end is located on the side of the heat sink fan away from the desiccant plate. One end of the ventilation pipe is connected to the inside of the cabinet, and the other end is connected to the inside of the heat sink.

[0038] The heat dissipation port is arranged on the side of the cabinet and is located above the cavity. One end of the heat dissipation port is connected with the inside of the cabinet, and the other end is connected with the outside. The heat dissipation port and the activated carbon filter plate are located on the same side.

[0039] When the staff finds that the alarm light is on, the staff will turn on the motor, the cooling ends of several refrigerators and the solenoid valve through the controller. The rotation of the motor drives the cooling fan to rotate. The rotation of the cooling fan allows the outside air to pass through the activated carbon filter. The activated carbon filter can effectively remove various odors from the outside and filter out impurities such as dust and particulate matter from the outside. The filtered air then passes through the cooling ends of several refrigerators and is cooled down by the cooling ends of several refrigerators, thereby forming low-temperature gas. The low-temperature gas then passes through the desiccant plate and adsorbs water vapor in the low-temperature gas, thereby increasing the dryness of the low-temperature gas. Finally, the low-temperature dry gas enters the cabinet through the ventilation pipe.

[0040] Furthermore, the heat dissipation and moisture-proof device includes a sealing plate, a support rod, a guide plate, two telescopic rods, and two telescopic springs. The sealing plate is arranged vertically, perpendicular to the front of the cabinet, and is arranged in the heat dissipation port, and is sealingly and slidingly connected with the inner wall of the heat dissipation port, and its sliding direction is arranged horizontally, parallel to the front of the cabinet.

[0041] The support rod is arranged horizontally and parallel to the front of the cabinet. The support rod is arranged on the side of the sealing plate away from the cabinet. One end of the support rod is fixedly connected to the side surface of the sealing plate.

[0042] The guide plate is arranged vertically, perpendicular to the front side of the cabinet, and the guide plate is arranged at the other end of the support rod and fixedly connected to the other end of the support rod.

[0043] The two telescopic rods are arranged horizontally and parallel to the front of the cabinet. The two telescopic rods are arranged between the guide plate and the cabinet and symmetrically arranged on both sides of the heat dissipation port. One end of the two telescopic rods is fixedly connected to the side surface of the guide plate, and the other end is fixedly connected to the side surface of the cabinet.

[0044] The two telescopic springs are respectively sleeved outside the two telescopic rods, one end of the two telescopic springs is fixedly connected to the side surface of the guide plate, and the other end is fixedly connected to the side surface of the cabinet.

[0045] As the low-temperature dry gas gradually enters the cabinet, the air pressure in the cabinet gradually increases. Driven by the air pressure, the sealing plate moves to the left until it is away from the heat dissipation port. At this time, the heat in the cabinet continuously returns to the outside from the heat dissipation port, which not only effectively reduces the temperature of the installation cabinet, but also effectively controls the humidity in the installation cabinet, thereby ensuring the normal operation of the installation cabinet.

[0046] Furthermore, the heat dissipation and moisture-proof device includes a scraper and a connecting rod. The scraper is arranged horizontally and perpendicular to the front of the cabinet. The scraper is arranged on the side of the activated carbon filter away from the refrigeration end of several refrigerators and is slidably connected to the side of the cabinet. Its sliding direction is arranged vertically, and the scraper is in close contact with the side surface of the activated carbon filter plate.

[0047] The connecting rod is arranged above the scraper, one end of the connecting rod is hinged to the upper surface of the scraper, and the other end is hinged to the lower surface of the guide plate.

[0048] When the sealing plate moves to the left, the sealing plate moves to the left, driving the support rod to move to the left, the support rod moves to the left, driving the guide plate to move to the left, the guide plate moves to the left, driving the upper end of the connecting rod to move to the left, the upper end of the connecting rod moves to the left, driving the lower end of the connecting rod to move upward, the lower end of the connecting rod moves upward, driving the scraper to move upward, the scraper moves upward, thereby effectively cleaning up impurities such as dust and particles accumulated on the activated carbon filter plate to avoid clogging of the activated carbon filter plate.

[0049] Furthermore, the leakage detection device includes a leakage detector, a fixing block, a groove, a T-shaped plug plate, a transmission cavity, a latch slot, an electromagnet, a first magnet, a plug rod, and two buffer springs. The leakage detector is arranged inside the cabinet, fixedly connected to the inner side of the cabinet, and electrically connected to the controller.

[0050] The fixing block is arranged on the side of the switch sealing door away from the guide plate, and the fixing block is arranged in front of the cabinet body and is fixedly connected with the side surface of the cabinet body.

[0051] The groove is arranged on the side surface of the fixing block close to the switch sealing door.

[0052] The T-shaped plug plate is arranged vertically and parallel to the front of the cabinet. The T-shaped plug plate is arranged in front of the switch sealing door and close to the fixed block. One end of the T-shaped plug plate is arranged in the groove and contacts with the groove. The T-shaped plug plate is slidably connected to the side surface of the switch sealing door, and its sliding direction is arranged horizontally.

[0053] The transmission cavity is arranged in the fixing block and is located above the groove.

[0054] The latch slot is arranged at one end of the T-shaped latch plate in the groove and is close to the transmission cavity.

[0055] The electromagnet is arranged on the top surface inside the transmission cavity, is fixedly connected to the top surface inside the transmission cavity, and is electrically connected to the controller.

[0056] The first magnet is arranged horizontally in the transmission cavity and below the electromagnet. The first magnet is slidably connected to the inner wall of the transmission cavity, and its sliding direction is arranged vertically.

[0057] The plug rod is arranged vertically, the upper end of the plug rod is fixedly connected to the lower surface of the first magnet, and the lower end of the plug rod passes through the middle of the fixing block and extends to the top of the pin slot.

[0058] Two buffer springs are vertically arranged below the first magnet and on both sides of the insertion rod. The upper ends of the two buffer springs are fixedly connected to the lower surface of the first magnet, and the lower ends are fixedly connected to the bottom surface of the transmission cavity.

[0059] When leakage occurs in the cabinet, the leakage detector detects the leakage and energizes the electromagnet. Since the magnetic poles of the electromagnet and the opposite side of the first magnet are the same, the first magnet moves downward under the action of repulsive force. The downward movement of the first magnet drives the insertion rod to move downward and insert into the latch slot, thereby locking the switch sealing door and the cabinet, preventing the staff from opening the switch sealing door without knowing it and touching the leakage part and getting an electric shock.

[0060] Furthermore, it comprises four supporting legs, which are vertically arranged below the heat sink and fixedly connected to the lower surface of the heat sink.

[0061] By setting four supporting legs, a supporting effect can be achieved.

[0062] Furthermore, a solenoid valve is fixedly connected to the inner wall of the ventilation pipe, and the solenoid valve is electrically connected to the controller.

[0063] By setting a solenoid valve, the cabinet can be kept in a sealed state.

[0064] Beneficial effects of the present invention: 1. The present invention provides a first conductive plate, two tension springs, an electrical contact, a second conductive plate, an alarm light and a battery, which interact and support each other. When the temperature in the installation cabinet rises, the alarm device can be automatically triggered to light up the alarm light, thereby promptly reminding the staff to take measures before the equipment is damaged.

[0065] 2. The alarm device and the heat dissipation and moisture-proof device provided in the present invention interact and support each other, which not only effectively reduces the temperature of the installation cabinet, but also effectively controls the humidity in the installation cabinet, thereby ensuring the normal operation of the installation cabinet.

[0110] As the low-temperature dry gas gradually enters the cabinet 1, the air pressure in the cabinet 1 gradually increases, and the sealing plate 507 moves to the left under the push of the air pressure, and the sealing plate 507 moves to the left until the sealing plate 507 is away from the heat dissipation port. At this time, the heat in the cabinet 1 continuously returns to the outside from the heat dissipation port, which not only effectively reduces the temperature of the installation cabinet, but also effectively controls the humidity in the installation cabinet, thereby ensuring the normal operation of the installation cabinet.

[0111] The heat dissipation and moisture-proof device includes a scraper 512 and a connecting rod 513. The scraper 512 is arranged horizontally and perpendicular to the front of the cabinet 1. The scraper 512 is arranged on the side of the activated carbon filter away from the refrigeration end 503 of the plurality of refrigerators, and is slidably connected to the side of the cabinet 1. Its sliding direction is arranged vertically, and the scraper 512 is in close contact with the side surface of the activated carbon filter plate 502.

[0112] The connecting rod 513 is arranged above the scraper 512 , one end of the connecting rod 513 is hinged to the upper surface of the scraper 512 , and the other end of the connecting rod 513 is hinged to the lower surface of the guide plate 509 .

[0113] When the sealing plate 507 moves to the left, the sealing plate 507 moves to the left, driving the support rod 508 to move to the left, the support rod 508 moves to the left, driving the guide plate 509 to move to the left, the guide plate 509 moves to the left, driving the upper end of the connecting rod 513 to move to the left, the upper end of the connecting rod 513 moves to the left, driving the lower end of the connecting rod 513 to move upward, the lower end of the connecting rod 513 moves upward, driving the scraper 512 to move upward, the scraper 512 moves upward, thereby effectively cleaning up impurities such as dust and particles accumulated on the activated carbon filter plate 502 to avoid clogging of the activated carbon filter plate 502.

[0114] The leakage detection device includes a leakage detector 601, a fixing block 602, a groove, a T-shaped plug plate 603, a transmission cavity, a latch slot, an electromagnet 604, a first magnet 605, a plug rod 606, and two buffer springs 607. The leakage detector 601 is arranged inside the cabinet 1 , fixedly connected to the inner side surface of the cabinet 1 , and electrically connected to the controller 7 .

[0115] The fixing block 602 is arranged on the side of the switch sealing door 3 away from the guide plate 509 . The fixing block 602 is arranged in front of the cabinet 1 and is fixedly connected to the side surface of the cabinet 1 .

[0116] The groove is arranged on the side surface of the fixing block 602 close to the opening and closing sealing door 3 .

[0117] The T-shaped plug plate 603 is arranged vertically and parallel to the front of the cabinet 1. The T-shaped plug plate 603 is arranged in front of the switch sealing door 3 and close to the fixed block 602. One end of the T-shaped plug plate 603 is arranged in the groove and contacts with the groove. The T-shaped plug plate 603 is slidably connected with the side surface of the switch sealing door 3, and its sliding direction is arranged horizontally.

[0118] The transmission cavity is arranged in the fixing block 602 and is located above the groove.

[0119] The latch slot is arranged at one end of the T-shaped latch plate 603 in the groove and is close to the transmission cavity.

[0120] The electromagnet 604 is arranged on the top surface of the transmission cavity, fixedly connected to the top surface of the transmission cavity, and electrically connected to the controller 7.

[0121] The first magnet 605 is disposed transversely in the transmission cavity and below the electromagnet 604. The first magnet 605 is slidably connected to the inner wall of the transmission cavity, and its sliding direction is vertically disposed.

[0122] The insertion rod 606 is arranged vertically, the upper end of the insertion rod 606 is fixedly connected to the lower surface of the first magnet 605, and the lower end passes through the middle of the fixing block 602 and extends to the top of the pin slot.

[0123] Two buffer springs 607 are vertically arranged below the first magnet 605 and on both sides of the insertion rod 606. The upper ends of the two buffer springs 607 are fixedly connected to the lower surface of the first magnet 605, and the lower ends are fixedly connected to the bottom surface of the transmission cavity.

[0124] When leakage occurs in the cabinet 1, the leakage detector 601 detects the leakage and energizes the electromagnet 604. Since the magnetic poles of the electromagnet 604 and the opposite sides of the first magnet 605 are the same, the first magnet 605 moves downward under the action of repulsion. The downward movement of the first magnet 605 drives the insertion rod 606 to move downward and insert it into the latch slot, thereby locking the switch sealing door 3 and the cabinet 1, preventing the staff from opening the switch sealing door 3 without knowing it and contacting the leakage part and getting an electric shock.

[0125] It includes four supporting legs, which are vertically arranged below the heat dissipation box 501 and fixedly connected to the lower surface of the heat dissipation box 501 .

[0126] By setting four supporting legs, a supporting effect can be achieved.

[0127] A solenoid valve is fixedly connected to the inner wall of the ventilation pipe, and the solenoid valve is electrically connected to the controller 7 .

[0128] By providing a solenoid valve, the cabinet 1 can be kept in a sealed state.

[0129] Working principle: When the temperature inside the installation cabinet rises, the air pressure inside the installation cabinet is greater than the external air pressure. At this time, the first conductive plate 401 moves to the left under the push of the air pressure. The first conductive plate 401 moves to the left, driving the electrical contact 403 to move to the left. The electrical contact 403 moves to the left into the through hole and contacts the second conductive plate 404. At this time, the electricity in the battery 407 passes through the first conductive plate 401, the electrical contact 403, and the second conductive plate 404 in turn, and is finally transmitted to the alarm light 406. Then the alarm light 406 lights up, thereby promptly reminding the staff to take measures before the equipment is damaged.

[0130] When the staff finds that the alarm light 406 is on, the staff turns on the motor 505, the refrigerators 503 and the solenoid valve through the controller 7. The rotation of the motor 505 drives the cooling fan 506 to rotate. The rotation of the cooling fan 506 allows the outside air to pass through the activated carbon filter. The activated carbon filter can effectively remove various odors from the outside and filter out impurities such as dust and particulate matter from the outside. The filtered air then passes through the cooling ends 503 of the refrigerators and is cooled under the action of the cooling ends 503 of the refrigerators, thereby forming a low-temperature gas. The low-temperature gas then passes through the desiccant plate 504 and adsorbs the water vapor in the low-temperature gas, thereby increasing the dryness of the low-temperature gas. Finally, the low-temperature dry gas enters the cabinet 1 through the ventilation pipe.

[0131] As the low-temperature dry gas gradually enters the cabinet 1, the air pressure in the cabinet 1 gradually increases, and the sealing plate 507 moves to the left under the push of the air pressure, and the sealing plate 507 moves to the left until the sealing plate 507 is away from the heat dissipation port. At this time, the heat in the cabinet 1 continuously returns to the outside from the heat dissipation port, which not only effectively reduces the temperature of the installation cabinet, but also effectively controls the humidity in the installation cabinet, thereby ensuring the normal operation of the installation cabinet.

[0132] When the sealing plate 507 moves to the left, the sealing plate 507 moves to the left, driving the support rod 508 to move to the left, the support rod 508 moves to the left, driving the guide plate 509 to move to the left, the guide plate 509 moves to the left, driving the upper end of the connecting rod 513 to move to the left, the upper end of the connecting rod 513 moves to the left, driving the lower end of the connecting rod 513 to move upward, the lower end of the connecting rod 513 moves upward, driving the scraper 512 to move upward, the scraper 512 moves upward, thereby effectively cleaning up impurities such as dust and particles accumulated on the activated carbon filter plate 502 to avoid clogging of the activated carbon filter plate 502.

[0133] When the heat dissipation is completed, the staff turns off the motor 505, the cooling ends 503 of several refrigerators and the solenoid valve through the controller 7. At this time, under the action of the two telescopic springs 511, the guide plate 509 moves to the right, and the movement of the guide plate 509 to the right in turn drives the upper end of the connecting rod 513 to move to the right and the support rod 508 to move to the right.

[0134] When the guide plate 509 moves to the right and drives the upper end of the connecting rod 513 to move to the right, the upper end of the connecting rod 513 moves to the right and drives the lower end of the connecting rod 513 to move downward, and the lower end of the connecting rod 513 moves downward and drives the scraper 512 to move downward, thereby effectively cleaning up impurities such as dust and particles accumulated on the activated carbon filter plate 502 to avoid clogging of the activated carbon filter plate 502.

[0135] When the guide plate 509 moves to the right and drives the support rod 508 to move to the right, the support rod 508 moves to the right and drives the sealing plate 507 to move to the right until the sealing plate 507 blocks the heat dissipation port, thereby effectively preventing untreated air from the outside from entering the installation cabinet and reducing the potential risk of equipment failure.

[0136] At this time, the first conductive plate 401 moves rightward under the action of the two tension springs 402, and the first guide plate 509 moves rightward to drive the electrical contact 403 to move rightward until the electrical contact 403 is away from the second conductive plate 404, and the alarm light 406 is no longer on.

[0137] When the electromagnet 604 is closed, the plug rod 606 is disengaged from the latch slot. When leakage occurs in the cabinet 1, the leakage detector 601 detects the leakage and energizes the electromagnet 604. Since the magnetic poles of the electromagnet 604 and the opposite sides of the first magnet 605 are the same, the first magnet 605 moves downward under the action of repulsive force. The downward movement of the first magnet 605 drives the plug rod 606 to move downward and insert it into the latch slot, thereby locking the switch sealing door 3 and the cabinet 1, preventing the staff from opening the switch sealing door 3 without knowing it and contacting the leakage part and getting an electric shock.

[0138] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
