Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power distribution, in particular to a safe power distribution cabinet. BACKGROUND

[0002] As a core component of the power system, the safety of the power distribution cabinet is directly related to the operation stability and personnel safety of industrial, commercial and residential places. Once a fire occurs in the power distribution cabinet, not only will it cause huge property losses, but also it may seriously threaten the safety of personnel and bring disastrous consequences to the enterprise. The reasons for the fire of the power distribution cabinet are various, including electric sparks caused by wire leakage, short circuit caused by damage of wire insulation layer, overheating phenomenon caused by long-time overload operation of wire, and burning of wire insulation layer caused by excessive contact resistance, etc.

[0003] Under the current technical background, although real-time monitoring of the temperature and gas in the power distribution cabinet can be used to prevent the occurrence of fire, due to the complex layout and large number of wires inside the power distribution cabinet, the failure of any group of wires may become a fuse to trigger a fire. Wire failure often has suddenness and uncertainty, and it is difficult to be discovered in time in the early stage of failure. Usually, only when the wire failure has or is about to cause a fire, the monitoring system can capture the related abnormal signals, which makes it difficult to effectively prevent and avoid the fire caused by wire failure. Once the failure occurs, the fire may spread rapidly, causing significant losses.

[0004] In view of the above problems, Chinese patent CN108598983B discloses a safety system of an electrical power distribution cabinet, which comprises a cabinet body, an electrical cavity is arranged inside the cabinet body, a through slot is formed at the back of the electrical cavity, a heat exchange plate is filled in the through slot, and the heat exchange plate seals the entire through slot; an outlet pipe is fixedly installed on one side of the inner wall of the electrical cavity, two bases are welded and fixed on one side of the outlet pipe, the bases are fixedly installed on the inner wall of the electrical cavity through screws, a plurality of electrical plates are rotatably arranged at the other end of the outlet pipe, and more than one electrical module is installed on each electrical plate.

[0005] However, when in use, the inert gas in the sealing film needs to be completely discharged every time the thorough overhaul is carried out, the inert gas cannot be recycled, and when overhauling, the operation is carried out through the sealing film. If the inert gas in the sealing film is too much to cause the sealing film to be in a full state, the operation of extruding the sealing film may cause the deformation of the sealing film, which is easy to cause the tearing of the sealing film, and there is inconvenience in use. Therefore, in view of the above technical problems, it is necessary to provide a safe power distribution cabinet. SUMMARY

Similarly, when opening, the locking plate 19 is driven to rotate into the slot by the handle and the rotating shaft 18, so as to open the protective cover 5.

[0046] The end of the rotating block 16 is fixedly connected with a top block 21, the rear side of the mounting plate 2 is provided with a fixed cylinder 22, the outer side of the fixed cylinder 22 is connected with a connecting pipe 23, the other end of the connecting pipe 23 is connected with the mounting plate 2, the mounting plate 2 is provided with a through hole in communication with the connecting pipe 23, the connecting pipe 23 is a hard pipe and can install the fixed cylinder 22 at the rear side of the mounting plate 2, the piston 24 is slidably arranged in the fixed cylinder 22, the piston 24 is provided with a movable rod 25, the end of the movable rod 25 is fixedly provided with an arc plate 26, when the protective cover 5 is rotated, the top block 21 can abut against the arc plate 26, the fixed cylinder 22 is further provided with a reset spring 27, the two ends of the reset spring 27 are fixedly connected with the piston 24 and the inner wall of the fixed cylinder 22 respectively;

[0047] When the protective cover 5 is opened, generally, the staff needs to overhaul or check, at this time, the protective cover 5 can be opened, and the rotating block 16 is rotated at the same time that the protective cover 5 is opened, the rotating block 16 drives the top block 21 to rotate, the top block 21 abuts against the arc plate 26 and drives the arc plate 26 to move when rotating, the arc plate 26 moves and drives the piston 24 to move in the fixed cylinder 22 through the movable rod 25, part of the inert gas in the protection cavity is extracted into the fixed cylinder 22, at this time, the isolation membrane 4 is in a relaxed state, the staff can directly overhaul the electrical module 3 and realize the action of opening the switch through the isolation membrane 4, since the isolation membrane 4 is in a relaxed state, the above-mentioned overhaul action will not cause deformation and harm to the isolation membrane 4, after the overhaul is completed, the protective cover 5 is covered again, at this time, the inert gas in the fixed cylinder 22 is retransported into the protection cavity, so that the isolation membrane 4 is filled up, the isolation membrane 4 can be away from the electrical module 3, and the influence of temperature is avoided.

[0048] The gas assembly one 6 includes a gas pump one 61 fixedly arranged at the bottom of the containing cavity, one end of the gas pump one 61 is connected with the gas tank 8 and the other end is provided with a gas conveying pipe one 62, the mounting plate 2 is provided with a branch pipe one 63 in communication with the gas conveying pipe one 62, the outer side of the branch pipe one 63 is provided with an electromagnetic valve, and the branch pipe one 63 is in communication with the protection cavity;

Therefore, the gas assembly two 7 is further arranged. The gas assembly two 7 comprises an air pump two 71 arranged at the bottom of the containing cavity. One end of the air pump two 71 is in communication with the outside, and the other end is provided with a gas delivery pipe two 72. The mounting plate 2 is provided with a branch pipe two 73 in communication with the gas delivery pipe two 72. An electromagnetic valve is arranged outside the branch pipe two 73. The branch pipe two 73 is in communication with the protection cavity. After the gas in the protection cavity is extracted, the air pump two 71 can fill the air in the protection cavity. Then the staff can take down the isolation membrane 4 to expose the electrical module 3 for maintenance. The electromagnetic valves are arranged outside each branch pipe one 63 and branch pipe two 73. During maintenance, one electrical module 3 on one mounting plate 2 can be maintained separately, without affecting the use of the remaining electrical modules 3.

The protection cavity formed between the mounting plate 2 and the isolation membrane 4 is filled with inert gas. The electrical module 3 can be in an inert gas environment during daily use, improving the safety of the equipment. During daily maintenance and inspection, only the protective cover 5 needs to be opened. At this time, part of the inert gas in the protection cavity is extracted into the fixed cylinder 22. At this time, the isolation membrane 4 is in a relaxed state. The staff can operate through the isolation membrane 4. Due to the relaxed state of the isolation membrane 4, the movement of some gate switches will not cause deformation and damage to the isolation membrane 4. When the maintenance is completed, the protective cover 5 is closed, and the isolation membrane 4 is filled again.

[0051] When a specific electrical module 3 in the power distribution cabinet needs to be replaced or repaired, the air pump one 61 can extract the inert gas in the protection cavity to the gas tank 8. Then the air pump two 71 sends air into the protection cavity, so that the air pressure inside and outside the isolation membrane 4 is the same. At this time, the fixed frame 11 is removed from the mounting plate 2. When the protective cover 5 is opened, it can drive the fixed frame 11 to open, thereby exposing the electrical module 3 for repair. After the repair is completed, the isolation membrane 4 is reinstalled, and then the protective cover 5 is closed. The air pump two 71 extracts the air in the protection cavity, and the air pump one 61 fills the inert gas in the protection cavity, thereby protecting the electrical module 3. The control center in the cabinet 1 controls the electrical components such as the air pump one 61, the air pump two 71 and the electromagnetic valve. It is prior art and will not be described here.

[0052] Embodiment 2: The application provides a technical scheme: embodiment 2 is same as the main body structure of embodiment 1, and the difference is that a water cooling pipe is arranged outside the gas tank 8, wherein the remaining structure of the water cooling system is prior art, which is arranged in the cabinet body 1, and details are not repeated here, the water cooling pipe can cool the tank body, and then cool the inert gas in the gas tank 8, so that when the power distribution cabinet is running, the air pump 61 can suck part of the inert gas in the protection cavity back into the gas tank 8, and then fill it into the protection cavity after cooling, so that the electrical module 3 is more stable during operation and is not affected by temperature.
