Description

Technical Field

[0001] The present invention belongs to the technical field of power distribution cabinet equipment, and specifically relates to a non-bolted busbar power distribution cabinet. Background Art

[0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets and metering cabinets, and are the end equipment of the power distribution system. Power distribution cabinets are the general term for motor control centers. Power distribution cabinets are used in occasions where the load is relatively scattered and the number of circuits is small, while motor control centers are used in occasions where the load is concentrated and the number of circuits is large. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby loads.

[0003] However, in the prior art, the use of busbars improves the reliability of the use of electrical equipment, but reduces the flexibility of the use of busbar power distribution cabinets. At the same time, busbars have relatively high requirements for the operating environment, and a poor operating environment is likely to cause busbar failures. Moreover, most existing busbars are limited in position by bolt limiting methods, which is not convenient for daily inspection, replacement and maintenance. At the same time, it is not convenient to adjust the installation position of the busbar, and thus it is impossible to conveniently install and set other electrical equipment according to the actual use situation, resulting in poor actual use effects of the existing busbar power distribution cabinets. Summary of the Invention

[0017] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are:

[0018] (1) In the present invention, during use, the support mechanism can be conveniently moved to the designated use position through the moving wheels. Then, the chassis can be firmly installed at the designated installation position through the mounting plate. At the same time, according to the actual installation requirements, the number of adjustment mechanisms can be increased or decreased. After rotating the side frame to the required angle, it is inserted between the designated two installation bars. At this time, under the support of the return spring, the positioning bar can extend into the corresponding positioning hole, so that the side frame can be firmly inserted between the corresponding installation bars, facilitating the installation and setting of different existing electrical equipment. Then, by rotating the bolt, the bolt can move along the installation groove to adjust the block, so that the block presses against and fits the outer surface of the side frame, so that the extension plate can be firmly set on a single or two side frames. At the same time, according to the actual busbar installation requirements, the placement position of the moving platform is adjusted. Then, the use position of the moving platform is fixed by rotating the positioning bolt. Then, the busbar is inserted between the two abutting plates. Then, by rotating and adjusting the abutting rod, the abutting rod presses against the moving abutting plate, so that the two abutting plates press against and fit both sides of the busbar, so that the busbar can be firmly set at the designated use position, facilitating the connection between the busbar and other electrical equipment. When the connection is completed, the storage mechanism carrying the busbar and other electrical equipment can be transferred between the chassis and the top frame through the moving frame. Then, by rotating the support worm, the rotating support worm and the support worm gear can drive the support screw rod to rotate. Then, the rotating support screw rod can adjust the use height of the support plate in the vertical direction, so that the support plate can drive the top frame to move down until the snap ring extends into the air guide frame. At this time, the storage mechanism can be firmly set between the chassis and the top frame. Then, the external power line is connected to the busbar through the mounting ring, so that the electrical equipment can operate normally. At the same time, according to the actual use requirements, by installing multiple support mechanisms at different use positions, and then moving and transporting the storage mechanism, the moving and replacement of different electrical equipment can be conveniently carried out, thereby improving the flexibility of the actual use of the equipment and enabling the equipment to efficiently realize its due functions.

[0019] (2) In the present invention, during use, by controlling the start of the first fan and the second fan, the second fan can inject the external low-temperature air into the installation frame. Under the action of the first fan, the excess heat generated by the operation of the busbar and other electrical equipment inside the installation frame can be accelerated and discharged, so that a relatively suitable operating environment can be maintained inside the installation frame, improving the actual operating effect of the internal electrical equipment and extending the service life of the internal electrical equipment. At the same time, by rotating the limit bolt, the limit bolt can move and adjust the limit block away from the installation frame, so that the protective frame can be quickly pulled out of the installation frame, so that the electrical equipment inside the installation frame can be fully exposed, facilitating the daily maintenance and repair and replacement of maintenance personnel, and enabling the equipment to efficiently realize its due functions.

At the same time, according to the actual busbar installation requirements, the placement position of the moving platform 308 is adjusted, and the use position of the moving platform 308 is fixed by rotating the positioning bolt. Then, the busbar is inserted between the two abutting plates 311. By rotating and adjusting the rod 310, the rod 310 presses against and moves the abutting plate 311, so that the two abutting plates 311 press against and fit both sides of the busbar, so that the busbar can be firmly arranged at the designated use position, facilitating the connection of the busbar to other electrical equipment. When the connection is completed, the storage mechanism 2 carrying the busbar and other electrical equipment can be moved to between the chassis 101 and the top frame 107 through the moving frame 205. By rotating the support worm 104, the rotating support worm 104 can drive the support screw rod 105 to rotate in cooperation with the support worm wheel, so that the rotating support screw rod 105 can adjust the use height of the support plate 106 in the vertical direction.

At this time, the storage mechanism 2 can be firmly arranged between the chassis 101 and the top frame 107. Then, the external power line is connected to the busbar through the mounting ring 204, so that the electrical equipment can operate normally. At the same time, according to the actual use requirements, by installing multiple support mechanisms 1 at different use positions, and then moving and transporting the storage mechanism 2, the movement and replacement of different electrical equipment can be conveniently carried out, thereby improving the flexibility of the actual use of the equipment and enabling the equipment to efficiently realize its due functions;

[0044] By controlling the startup of the first fan 108 and the second fan 207, the second fan 207 can inject the outside low-temperature air into the interior of the mounting frame 201. Under the action of the first fan 108, the excess heat generated by the operation of the busbars and other electrical equipment inside the mounting frame 201 can be discharged at an accelerated rate, enabling a relatively suitable operating environment to be maintained inside the mounting frame 201, improving the actual operating effect of the internal electrical equipment, extending the service life of the internal electrical equipment. At the same time, by rotating the limit bolt 208, the limit bolt 208 can move to adjust the limit block 209 away from the mounting frame 201, and then the protective frame 206 can be quickly removed from the mounting frame 201, enabling the electrical equipment inside the mounting frame 201 to be fully exposed, thus facilitating the daily maintenance and repair and replacement by maintenance personnel, and enabling the equipment to efficiently achieve its due functions.
