Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to an AC metal-enclosed ring network switch device. Background Art

[0002] Closed ring main switchgear is a high voltage circuit breaker with a metal enclosure structure. It can effectively isolate, control and protect the power system during the operation of high voltage electrical equipment.

[0003] In order to ensure the safety of the closed ring network switchgear during operation, the structure is designed to ensure that the equipment is fully sealed.

[0004] The existing closed ring network switchgear has good cabinet sealing performance, so when it is in use, the operation of the internal electrical equipment generates heat, causing the overall temperature in the cabinet to rise. The temperature can only be reduced by heat exchange between the cabinet surface and the external environment, resulting in heat accumulation inside the ring network equipment, causing a safety hazard.

[0005] Based on this, the utility model designs an AC metal-enclosed ring network switch device to solve the above problems. Utility Model Content

[0006] The utility model aims to provide an AC metal-enclosed ring network switch device to solve the above technical problems.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising a cabinet body, a guide plate is fixedly arranged in the cabinet body, and a heat absorbing water inlet and a heat absorbing water outlet are provided on the guide plate; a sub-cabinet is fixedly arranged on the cabinet body, a rotating motor is fixedly arranged on the sub-cabinet, a cross-flow fan blade is fixedly arranged on the output shaft of the rotating motor, a guide plate is fixedly arranged on the sub-cabinet, and an air outlet and an air inlet are provided on the sub-cabinet; a heat sink is fixedly arranged on the sub-cabinet, and a heat release water inlet and a heat release water outlet are provided on the heat release water outlet; a water pump is fixedly arranged on the heat release water outlet, and a water inlet pipe is connected between the water outlet of the water pump and the heat absorbing water inlet; a water outlet pipe is connected between the heat absorbing water outlet and the heat release water inlet, and a liquid replenishing tank is fixedly arranged on the water outlet pipe; the guide plate is filled with coolant.

[0008] By adopting the above technical solution, the water pump allows the coolant in the system to flow between the guide plate and the heat sink. After the heat generated in the cabinet is absorbed by the guide plate, the coolant flows to the heat sink to exchange heat with the air. The setting of the cross-flow fan blades improves the heat exchange efficiency between the air and the heat sink, thereby achieving the effect of cooling the inside of the cabinet.

[0009] Preferably, an automatic exhaust valve is fixedly provided on the fluid infusion tank.

[0010] By adopting the above technical solution, the overflow of the coolant due to volume expansion when the temperature rises can be avoided, thereby ensuring the safety performance of the cabinet and the auxiliary cabinet.

[0011] Preferably, heat absorbing fins are fixedly provided on the guide plate, and a plurality of heat absorbing fins are provided.

[0012] By adopting the above technical solution, the setting of the heat-absorbing fins makes the contact area between the guide plate in the cabinet and the air in the cabinet cavity larger, which can absorb the heat in the cabinet more quickly and achieve the effect of cooling the cabinet.

[0013] Preferably, a heat dissipation fin is fixedly arranged on the heat dissipation plate, and a plurality of the heat dissipation fins are arranged.

[0014] By adopting the above technical solution, the setting of the heat dissipation fins makes the contact area between the guide plate in the cabinet and the flowing air larger, which can absorb the heat in the cabinet more quickly and achieve the effect of cooling the cabinet.

[0015] Preferably, a temperature sensor is fixedly installed in the cabinet, a controller is fixedly installed on the sub-cabinet, and the rotating motor, water pump and temperature sensor are electrically connected to the controller.

[0016] By adopting the above technical solution, the setting of the temperature sensor makes it possible to control the working state of the water pump, and the working speed of the water pump is driven by detecting the temperature change in the cabinet, so that the coolant exchange speed between the drainage plate and the heat sink increases when the temperature is too high.

[0017] Preferably, anti-intrusion nets are fixedly provided on the air outlet and the air inlet.

[0018] By adopting the above technical solution, it is possible to avoid the situation where foreign matter invades the cross-flow fan blades, causing the air flow in the auxiliary cabinet to be unable to circulate, resulting in the temperature of the auxiliary cabinet to rise and affecting the heat dissipation of the heat sink.

[0019] In summary, the present application has the following beneficial technical effects: the heat in the cabinet is absorbed by the guide plate with heat-absorbing fins, and the heat is transferred to the coolant circulating between the guide plate and the heat sink, and then transferred to the heat sink and the heat sink fins. After the heat sink and the heat sink fins exchange heat with the air in the sub-cabinet, the cross-flow fan blades rotate to accelerate the air flow in the sub-cabinet, so that the heat generated by the equipment is transferred to the sub-cabinet and then exchanged with the air, avoiding heat accumulation inside the equipment, which has the advantage of improving the safety of the equipment in use.

[0034] The implementation principle of this embodiment is as follows: when the AC metal-enclosed ring network switchgear is in operation, the driving controller 23 works, and the temperature in the cabinet 1 is measured by the temperature sensor 22; when the value measured by the temperature sensor 22 reaches a certain threshold, the controller 23 drives the rotating motor 7 and the water pump 17 to work, and the rotating motor 7 drives the crossflow fan blades 8 to rotate, so that the gas in the auxiliary cabinet 6 flows with the outside air, and the water pump 17 drives the coolant in the heat sink 13 to flow from the water inlet pipe 18 to the guide plate 2, and the coolant in the guide plate 2 and the heat sink 13; when the colder coolant flows through the guide plate 2, the heat on the guide plate 2 is taken away, so that the guide plate 2 and the heat-absorbing fins 5 can continuously absorb the heat generated inside the cabinet 1; after absorbing the heat, the coolant flows back to the heat sink 13 from the outlet pipe 19, and transfers the heat to the colder heat sink 13 and the heat sink fins 14, so that the heat is exchanged on the heat sink 13 and the heat sink fins 14 with the gas flowing in the auxiliary cabinet 6, thereby achieving the purpose of cooling the inside of the cabinet 1.

[0035] The heat in the cabinet 1 is absorbed by the guide plate 2 with the heat-absorbing fins 5, and the heat is transferred to the coolant circulating between the guide plate 2 and the heat sink 13, and then transferred to the heat sink 13 and the heat sink fins 14. After the heat sink 13 and the heat sink fins 14 exchange heat with the air in the sub-cabinet 6, the cross-flow fan blades 8 rotate to accelerate the air flow in the sub-cabinet 6, so that the heat generated by the equipment is transferred to the sub-cabinet 6 and then exchanged with the air, thereby avoiding heat accumulation inside the equipment, which has the advantage of improving the safety of the equipment in use.
