[0002] Distribution devices are a general term for equipment and systems used to receive, distribute and control electrical energy. They play a vital role in the power system, ensuring that electrical energy is safely and efficiently transmitted from power stations or substations to end users. Early distribution devices required operation and maintenance personnel to manually adjust according to load conditions to maintain the balance of three-phase current. Currently, three-phase load imbalance automatic adjustment devices (NSPC series) are generally used in distribution cabinets to achieve management. This device is mainly aimed at automatic adjustment of three-phase load imbalance, and can also be equipped with dynamic reactive power compensation, voltage support and harmonic current compensation functions.
[0003] 1. The distribution cabinet in the prior art needs to be regularly inspected and maintained during use. When the maintenance personnel repair the electrical components inside the main body of the distribution cabinet, the open movable door is easily rotated by the wind or other unexpected external forces because the distribution cabinet lacks a limit function for the movable door, which can easily cause pinching injuries to the maintenance personnel.

[0027] like Figure 1 , Figure 2 As shown, a power distribution device for three-phase unbalance treatment includes a power distribution cabinet body 1, a mounting seat 2 is fixedly connected to the bottom of the power distribution cabinet body 1, a mounting groove 3 is provided at the left end of the top surface of the mounting seat 2, an arc-shaped slide groove 4 is provided on the left side surface of the mounting seat 2, and extends to the inside of the mounting groove 3. A positioning mechanism 5 is provided inside the mounting groove 3. A movable door 6 is provided at the front end of the left side of the power distribution cabinet body 1 through a hinge rotation. A buffer mechanism 7 is fixed inside the power distribution cabinet body 1. More specifically, the three-phase unbalance automatic adjustment device is installed on the surface of the buffer mechanism 7, and the three-phase unbalance automatic adjustment device is installed on the surface of the buffer mechanism 7. The phase imbalance automatic adjustment device controls the three-phase imbalance problem, and protects the interior through the distribution cabinet body 1 and the movable door 6. By providing a positioning mechanism 5, when repairing the electrical components inside the distribution cabinet body 1, the positioning mechanism 5 can be used to limit the movable door 6 to prevent the open movable door 6 from rotating and causing injuries to the maintenance personnel. By providing a buffer mechanism 7, the internal electrical components are damped, and the vibration generated by the three-phase imbalance automatic adjustment device during operation is avoided and absorbed, thereby avoiding failures due to long-term vibration.
[0028] like Figure 4As shown, the positioning mechanism 5 includes a locking pin 501, and the two ends of the locking pin 501 are respectively fixedly connected to the left inner wall and the right inner wall of the installation groove 3. The outer part of the locking pin 501 is rotatably connected to a door block 502, and the door block 502 is located inside the installation groove 3. A threaded hole 503 is penetrated at one end of the left side of the door block 502 close to the locking pin 501. A fastening bolt 504 is threadedly connected inside the threaded hole 503. The fastening bolt 504 movably penetrates the arc-shaped slide groove 4. The arc-shaped slide groove 4 is arranged in an arc shape. The center of the arc trajectory of the arc-shaped slide groove 4 is on the same straight line as the center of the locking pin 501. More specifically, When maintenance is performed, the movable door 6 is rotated to fit the left side of the distribution cabinet body 1, the fastening bolt 504 is loosened and the fastening bolt 504 is slid along the arc-shaped slide groove 4, thereby driving the door block 502 to rotate around the locking pin 501 to the left side of the movable door 6, thereby blocking the movable door 6 to prevent the movable door 6 from rotating and pinching the maintenance personnel. The fastening bolt 504 can be tightened so that the end of the fastening bolt 504 abuts against the right inner wall of the installation groove 3, thereby limiting the rotation of the door block 502, preventing the door block 502 from rotating freely, and improving the stability of the door block 502.
[0029] like Figure 3 As shown, the buffer mechanism 7 includes a mounting plate 701, which is fixedly connected to the lower part of the inner wall on the back of the power distribution cabinet body 1.

The top ends of the two sliding rods 702 are commonly fixedly connected to an electrical mounting frame 703. The electrical mounting frame 703 is located inside the power distribution cabinet body 1. The outer fixed sleeves of the two mounting plates 701 are provided with springs 704. The top ends of the springs 704 are fixedly connected to the bottom surfaces of the electrical mounting frames 703. The lower ends of the springs 704 are fixedly connected to the top surface of the mounting plate 701. The top surface of the mounting seat 2 is fixedly connected to two hydraulic damping rods 705 distributed on the left and right.

The top ends of the output shafts of the two hydraulic damping rods 705 movably penetrate the mounting plate 701 and extend to the bottom surface of the electrical mounting frame 703, and are fixedly connected to the bottom surface of the electrical mounting frame 703. More specifically, the electrical mounting frame 703 is provided to fix and install a three-phase unbalanced automatic adjustment device. When the three-phase unbalanced automatic adjustment device vibrates during operation, the vibration is effectively absorbed by the joint cooperation of the two springs 704 and the two hydraulic damping rods 705, thereby preventing the three-phase unbalanced automatic adjustment device fixed on the electrical mounting frame 703 from being damaged by vibration.
[0030] like Figure 1 , Figure 2As shown, two ventilation mechanisms 8 distributed up and down are fixedly provided on the right side of the distribution cabinet body 1. More specifically, by setting up the ventilation mechanism 8, the electrical components inside the distribution cabinet body 1 are dissipated and cooled, thereby preventing the electrical components inside the distribution cabinet body 1 from being damaged by high temperature.
[0031] like Figure 1 , Figure 2 As shown, a rainproof top plate 9 is fixedly connected to the top surface of the power distribution cabinet body 1. More specifically, by providing the rainproof top plate 9, it plays a role in diverting rainwater from the power distribution cabinet body 1, thereby preventing rainwater from directly washing the power distribution cabinet body 1.
