Description

Technical Field

[0002] High and low voltage distribution cabinet is a kind of equipment used for power distribution in power system. It is mainly used for receiving, controlling, protecting and distributing power. Its main function is to reduce the voltage of power from high voltage grid to low voltage through transformer, or distribute low voltage current to various electrical equipment.

[0054] The use method and advantages of the present invention: The high and low voltage distribution cabinet for electric power has the following working process:

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 As shown:

[0056] S1: When the inside of the power distribution cabinet becomes hot, the drive motor 502 and the air supply device 512 are started to operate synchronously. The drive motor 502 arranged under the protective plate 8 drives the wheel 503 connected to its output shaft to rotate. The transmission head 504 fixedly connected to the bottom end of the wheel 503 performs a circular motion around the axis of the wheel 503. When the transmission head 504 rotates, it slides inside the slide 505, generating a thrust in the circumferential direction. This thrust drives the slide 505 to slide from one side of the top of the cabinet 2 to the other side. During the sliding process, the slide 505 passes through the bottom The telescopic rod 506 connected to the top drives the transmission rod 508 and the heat dissipation pipe 515 to slide synchronously, and the sliding through the frame 514 drives the air supply device 512 to slide from one end of the hanger 511 to the other end. The adapter 509 connected to the top and bottom of the heat dissipation pipe 515 slides from the hook of the guide groove 518 to the straight part. During the process, the telescopic tube 510 connected between the two steering tubes 513 is stretched outward, which is convenient for the normal transportation of air. The air is transported to the inside of the heat dissipation pipe 515 through the air supply device 512, the steering tube 513 and the telescopic tube 510;

[0057] S2: When the heat dissipation pipe 515 moves from the corner of the cabinet 2 to the front side of the component 3, the gear 1 602 meshing with the track rack 601 rotates, and the end of the lever 603 is stuck in the tooth groove 605 through the lever 603 abutting against the spring sheet 604, so that when the gear 1 602 rotates, the adapter 509 under the heat dissipation pipe 515 is driven to rotate continuously, thereby driving the heat dissipation pipe 515 to rotate counterclockwise. When the heat dissipation pipe 515 rotates, the air emitted from the through hole 516 can blow away the dust on the component 3, and blow synchronously with the moving direction of the heat dissipation pipe 515, so that the dust on the component 3 can be cleaned during the heat dissipation process. After the movable head 504 rotates 180 degrees, the transmission head 504 continues to perform circular motion, so that the slide seat 505 returns to the initial position, and the heat dissipation mechanism 5 returns as a whole. When the heat dissipation pipe 515 returns, the gear 1 602 rotates in the opposite direction. During the process, the support rod 603 does not get stuck on the tooth groove 605, but rubs against the surface of the tooth groove 605 and frequently passes through it, and compresses the spring sheet 604 for a distance, so that the heat dissipation pipe 515 does not rotate when returning, which can prevent the dust on the component 3 from being blown in the opposite direction, thereby preventing the dust from being dispersed, and the through hole 516 on the heat dissipation pipe 515 can make the air blow directly to the component 3, further improving the heat dissipation effect on the component 3;

[0058] S3: While the inside of the cabinet 2 is being cooled, the slide 505 drives the upper and lower contacts 701 to move synchronously through the frame 514. When the heat dissipation pipe 515 performs cooling and blowing operations on the components 3 at the same time, the contact 701 located above the frame 514 moves, and the contact 701 contacts the surface of the baffle 706 and abuts against the baffle 706. As the frame 514 gradually moves, the upper contact 701 pushes the upper wedge rod 705 toward the cabinet 2, so that the horizontal bar 703 compresses the spring 1 704, and the upper horizontal bar 703 drives the spring 1 704 to move. A ventilation rack 708 connected thereto moves synchronously, causing the ventilation rack 708 transmission gear No. 2 711 to rotate. When the frame 514 moves to the end of the bracket 511, the upper contact 701 disengages from the inclined surface of the wedge-shaped rod 705. When returning to its original position, it passes through the other side of the wedge-shaped rod 705 and approaches the head end of the bracket 511, pushing the baffle 706 hinged on the wedge-shaped rod 705, so that the spring No. 2 707 is stretched. When the upper contact 701 is completely disengaged from the baffle 706, the baffle 706 automatically returns to its original position in an inclined state under the pulling force of the spring No. 2 707.

[0059] S4: When the heat dissipation pipe 515 performs heat dissipation and blowing operations at the same time, the upper horizontal bar 703 drives the ventilation rack 708 to move, and drives the three gears 711 to rotate synchronously. Each group of Z-shaped plates 710 rotates synchronously through the belt 712, and changes from a closed state to an open state, so that the dust blown down can be output to the inside of the cabinet 2, and the cabinet 2 is in a state where one side is closed and the other side is open, so that the heat can be taken away during heat dissipation, and the heat can be directly discharged from the outside of the cabinet 2.

[0060] The above shows and describes the basic principles, main features and advantages of the present invention. Technical personnel in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
