These devices are combined in a grounded metal shell according to the wiring requirements of the primary system diagram, and the internal space uses air, insulating gas or solid insulating material as the insulating medium.

[0003] Switchgear is usually composed of multiple functional rooms to ensure the safe and reliable operation of the power system, including busbar room, trolley room, cable room and relay instrument room. The cable room is used to connect the cables entering and leaving the switchgear. The cables enter or leave the switchgear through the cable room and are connected to the switchgear on the busbar or trolley. The design of the cable room needs to consider issues such as cable fixing, sealing and protection to ensure safe and reliable cable connection.

[0004] Cables generate heat in the process of transmitting electrical signals or electrical energy. If the heat in the cable chamber cannot be discharged in time, the cable temperature will continue to rise, which may cause safety faults such as insulation aging, short circuit, overload, etc., and shorten the service life of the cable. Summary of the invention

[0005] In order to extend the service life of the cable, the present application provides an AC high-voltage intelligent switch cabinet.

[0006] The present application provides an AC high-voltage intelligent switch cabinet adopting the following technical solution:

[0007] An AC high-voltage intelligent switch cabinet comprises a cabinet body, a cabinet door, a dust screen, a filter screen and a fan, wherein a cable trough is provided on one side of the cabinet body, the cabinet door is hinged to the cabinet body, the hinge axis of the cabinet door is vertical, the cabinet door is used to cover the notch of the cable trough, the cabinet door is provided with an air inlet, and an air outlet is provided at one end of the cabinet body away from the cabinet door, the air inlet and the air outlet are both connected to the cable trough, the dust screen is fixedly connected to the inner wall of the air inlet, the filter screen and the fan are fixedly connected to the inner wall of the air outlet, and the filter screen is arranged on the side of the fan away from the cable trough.

The filter and dustproof net can reduce the probability of external impurities entering the cable trough and extend the service life of the cable.

[0009] Preferably, it also includes a cooling pipe, which is arranged on a side of the dustproof net close to the cable trough, and the cooling pipe is fixedly connected to the inner wall of the air inlet.

[0010] By adopting the above technical solution, before the air enters the cable trough from the air inlet, it first exchanges heat with the cooling pipe to reduce the air temperature, facilitate heat dissipation of the cable, and extend the service life of the cable.

[0012] By adopting the above technical solution, the water-absorbent and breathable cotton absorbs small droplets in the air, reduces the impact of moisture on the cable, allows relatively dry air to contact the cable, and extends the service life of the cable.

[0013] Preferably, the height of the upward inner wall of the air inlet decreases as it moves away from the cable trough.

[0014] By adopting the above technical solution, when air with a high water content exchanges heat with the cooling pipe, it condenses into small water droplets on the outer wall of the cooling pipe. After falling, the small water droplets flow along the inner wall of the air inlet in a direction away from the cable trough, thereby reducing the impact on the cable and extending the service life of the cable.

[0015] Preferably, it also includes a filter plate, the inner wall facing upwards of the air inlet is provided with a cooling groove, the cooling groove is arranged between the cooling pipe and the dustproof net, the filter plate is fixedly connected to the inner wall of the groove of the cooling groove, and the upper end surface of the filter plate is coplanar with the inner wall facing upwards of the air inlet.

The water in the cooling tank can exchange heat with the cabinet, which is convenient for the heat dissipation of the cable. The filter plate reduces the probability of external impurities entering the cooling tank.

[0018] By adopting the above technical solution, when the water temperature in the cooling pipe is high, the blocking block slides to open the drain port, and the water pump starts to extract water from the cooling tank to supply the cooling pipe, thereby replacing the water in the cooling pipe and lowering the temperature of the cooling pipe, making it easier to cool the air passing through the air inlet and extending the service life of the cable.

[0019] Preferably, it also includes a support plate, a memory alloy, a sliding plate and a first spring, the support plate is fixedly connected to the inner wall of the cooling tube, the support plate is provided with a through hole, the memory alloy passes through the through hole, the sliding plate is arranged on the side of the support plate away from the blocking block, one end of the memory alloy is fixedly connected to the sliding plate, the other end of the memory alloy is fixedly connected to the blocking block, the first spring is arranged between the sliding plate and the support plate, the first spring is sleeved on the outer periphery of the memory alloy, one end of the first spring is connected to the sliding plate, and the other end of the first spring is connected to the support plate.

[0020] By adopting the above technical solution, the first spring maintains the distance between the sliding plate and the support plate when not subject to external force. When the water temperature in the cooling pipe reaches the deformation temperature of the memory alloy, the memory alloy deforms and elongates to push the blocking block to move, so that the drain port is opened. When there is less water in the cooling tank, the first spring can be controlled to be in an extended state to reduce water waste.

[0022] By adopting the above technical solution, the blocking block slides to open the drain outlet and abuts against the switch to control the water pump to start, replenishing the water discharged from the cooling pipe, ensuring that the cooling pipe is full of water, facilitating the cooling of the air entering the air inlet, facilitating the heat dissipation of the cable, and extending the practical life of the cable.

[0023] Preferably, it also includes a blocking block, a second spring, a pull rope, a weight block and a floating plate, the blocking block is arranged between the blocking block and the switch, the blocking block is slidably connected to the upper end of the mounting block, one end of the second spring is fixedly connected to one end of the fixing frame facing the mounting block, the other end of the second spring is fixedly connected to the blocking block, one end of the pull rope is fixedly connected to the blocking block, the other end of the pull rope is fixedly connected to the weight block after passing through the filter plate, the floating plate is slidably connected to the slot wall of the cooling slot, and the weight block is fixedly connected to the upper end of the floating plate.

[0024] By adopting the above technical solution, when the water storage volume in the cooling tank is small, the weight block pulls the blocking block to move through the pull rope, the second spring stretches, and the blocking block blocks the movement of the blocking block, so that the drain outlet cannot be opened, reducing water waste.

[0025] Preferably, an upward inner wall of the air outlet is provided with a receiving groove, and the receiving groove is provided between the filter screen and the fan.

[0026] By adopting the above technical solution, if foreign impurities or insects enter the air outlet through the filter, the fan rotates to blow the impurities or insects into the receiving groove, thereby reducing the probability of foreign impurities entering the cable groove.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The rotation of the fan allows air to flow in through the air inlet and out through the air outlet, accelerating the air circulation in the cable trough and facilitating the heat dissipation of the cable.
