Description

Technical Field

[0001] The present invention relates to the technical field of switchgear, and in particular to a low-voltage complete switchgear. Background Art

[0002] Low-voltage complete sets of equipment refer to complete sets of equipment used in voltage levels of 380V and below. The latter is considered from a safety perspective, but the two are not contradictory, because in the power transmission and distribution system, low-voltage electrical appliances refer to the 380V distribution system. Therefore, in actual work, low-voltage complete sets refer to electrical equipment used in voltage levels of 380V and below.

[0003] Low-voltage complete equipment is an integrated electrical equipment used for power distribution, control and protection in power systems. It usually includes switchgear, measuring instruments, protection devices and connecting wires. These components are assembled in a closed metal cabinet to achieve centralized management and operation of the electrical system.

[0004] Low-voltage complete sets of equipment involve many aspects, including electrical engineering, mechanical design, automatic control, information technology and environmental science. With the continuous advancement of technology, low-voltage complete sets of equipment are also constantly developing towards intelligence, networking and green environmental protection.

[0005] The temperature control of low-voltage complete sets of equipment requires precise control. When the temperature of the equipment is too high, it will affect the operation of the equipment. When the temperature is low, the resistance of the insulating materials in the equipment will decrease, the insulation performance will decrease, the risk of leakage will increase, and the operation of electronic components will be affected. At the same time, when the equipment is used outdoors, it cannot form effective protection, causing the equipment to be damaged by other external factors.

[0006] Therefore, the present invention provides a low-voltage complete switchgear to solve the above problems. Summary of the invention

[0010] Preferably, the bottom of the water collecting tank is connected with a water suction pipe, the inside of the water suction pipe is rotatably connected with an impeller, the main shaft of the impeller is located outside the water suction pipe, and the outer wall of the impeller is fixedly mounted with an impeller bevel gear, the bottom of the electrical box is rotatably connected with a rotating shaft, the outer wall of one end of the rotating shaft is fixedly mounted with a first rotating bevel gear, the first rotating bevel gear is meshingly connected with the impeller bevel gear, the outer wall of the other end of the rotating shaft is fixedly mounted with a second rotating bevel gear, the second rotating bevel gear is meshingly connected with the connecting bevel gear; A water pump is installed inside the bottom of the electrical box, and the water inlet end of the water pump is connected to the water outlet end of the water pump pipe, and the water outlet end of the water pump is installed with an outlet pipe, and the water outlet end of the outlet pipe is connected to the water inlet end of the first water tank, and a cooling fan is installed on the outer wall of the outlet pipe, and the number of the cooling fans is multiple; when the device is in the initial state, when the temperature of the equipment is low, the cooling water inside the first water tank will flow into the inside of the water collecting tank through the first heat sink, so that the cooling water inside the first water tank dissipates heat and cools down the components inside the switch box. When the temperature is high, the cooling water inside the second water tank will be started to dissipate heat through the second heat sink. When dissipating heat, the cooling water inside the water collecting tank will be extracted by the water pump, circulated to the inside of the water tank through the outlet pipe, and after the water collecting tank discharges the absorbed heat When cooling water is applied, the impeller will be driven, and the reciprocating screw will be driven to rotate under the action of the rotating shaft. At this time, the reciprocating screw will drive the cleaning brush to move back and forth up and down to clean the outer wall of the heat sink.

When the protective plate is subjected to external force, the protective plate will drive the limiting plate to slide to the inside of the contraction groove. At this time, under the action of the compression spring, the compression airbag is instantly inflated into the inside of the inflatable airbag, so that the inflatable airbag protects the electrical box; through the setting of the airbag, the device can instantly protect the electrical box when subjected to external force. At the same time, the protective plate of the device can play a role of primary protection, and the airbag plays a role of double protection, which prevents the electrical box from being damaged again after being subjected to external force, thereby ensuring the safe use of the electrical box.

[0013] Preferably, a slide groove is provided on the outer wall of the guide plate, the sliding block is slidably connected inside the slide groove, a clamping block is fixedly installed inside the slide groove, and the clamping block matches the sliding block.

When the temperature drops, the dual-way heat dissipation can be automatically turned off to achieve single-way heat dissipation to avoid energy waste. The second water tank of the device is set outside the first water tank, so that the second water tank of the device can dissipate heat for the first water tank. At the same time, when the operating power of the equipment is low, the second water tank stores the previous temperature, which can avoid the phenomenon of low temperature of the equipment itself and long-term single-way heat dissipation at a low temperature when the single-way heat dissipation is performed.

[0019] 4. Through the setting of the airbag, this device can instantly protect the electrical box when it is subjected to external force. At the same time, the protective plate of this device can play the role of primary protection, and the airbag plays the role of double protection, preventing the electrical box from being damaged again after being subjected to external force, thereby ensuring the safe use of the electrical box.

[0020] 5. When the inflatable airbag of the device is injected with gas, the inflatable airbag will unfold, and the slider will slide inside the slide groove. When sliding to the extreme position, the clamping shaft will be inserted into the limiting groove. At this time, the umbrella block will be clamped with the limiting column, so that the clamping block can limit the unfolded inflatable airbag, so that the inflatable airbag of the device can wrap the electrical box to achieve protection and prevent the airbag from falling off and shaking.

[0021] 6. When the inflatable airbag of the device is inflated, it will be inflated through the main airbag at the same time. The lower pressure plate presses down the main airbag to achieve the function of dual air supply, which can quickly prop up the inflatable airbag and avoid the phenomenon of insufficient gas in the compressed airbag.

When the heat is dissipated, the cooling water in the water collecting tank 8 will be extracted by the water pump 807 and circulated to the inside of the water tank through the outlet pipe 808. When the cooling water after absorbing heat is discharged from the water collecting tank 8, the impeller 802 will be driven, and the reciprocating screw 9 will be driven to rotate under the action of the rotating shaft 804. At this time, the reciprocating screw 9 will drive the cleaning brush 10 to move up and down to clean the outer wall of the heat sink. The first water tank 201 of the device The connection structure between the second water tank 202 and the water collecting tank 8 is the same as the connection structure between the second water tank 202 and the water collecting tank 8; the cooling water of the device can be dissipated through the cooling fan 809, and recycled after heat dissipation to avoid the waste of cooling water. At the same time, the cleaning brush 10 of the device can automatically clean the outer wall of the heat sink to avoid the poor heat dissipation effect caused by the adhesion of dust and other substances, thereby ensuring its heat dissipation effect.
