[0024] according to Figure 1-2 and Figure 4-5 As shown, the limiting mechanism 4 includes a slide groove 401, a limiting rod 402, a limiting spring 403 and a limiting hole 404. Slide grooves 401 are provided at both ends of the front sealing plate 2. The slide groove 401 is slidably connected to the second slider 14. The interior of the second slider 14 passes through the limiting rod 402. The outer side of the limiting rod 402 is sleeved with the limiting spring 403. The front sealing plate 2 is provided with limiting holes 404 on both sides close to the limiting rod 402. The number of the limiting holes 404 is four.

[0025] During specific implementation, since the control panel 12 of the distribution network controller will be exposed to the outside, it is convenient for the staff to operate. However, when not in operation, it may be exposed to the outside and may be hit by other objects, causing damage to the control panel 12.

The screw 703 is installed inside the housing 1 through a bearing. The outer side of the screw 703 is threadedly sleeved with the No. 1 slider 701. The lower side of the No. 1 slider 701 is connected to the connecting block 702. One end of the screw 703 is fixedly sleeved with the No. 1 gear 704. One side of the No. 1 gear 704 is meshed with the No. 2 gear 705.

[0027] During specific implementation, while the distribution network controller is working, the internal integrated circuit board 11 will generate heat, and the heat will be dissipated from the heat dissipation holes 10 and undergo air convection. During air convection, the dustproof net 9 can block dust from entering the cover 1 to prevent dust from affecting the operation of the integrated circuit board 11. While dissipating heat, some dust may adhere to the dustproof net 9 and need to be cleaned in time. The motor 8 can be used to regularly drive the second gear 705 to rotate, so that the second gear 705 drives the first gear 704 to rotate, and the first gear 704 drives the screw 703 to rotate, and then the first slider 701 moves to one side on the screw 703, and the first slider 701 drives the connecting block 702 to move to one side.

[0028] Working principle: When using this kind of distribution network controller, first, install the distribution network controller where it needs to be installed, then connect the power cord at the power interface 5, and then connect the wire at the line interface 6. The control panel 12 can be operated, and then the integrated circuit board 11 monitors the power factor in the power system and adjusts it according to the set value to control the connection status of the inductive capacitor or inductive reactor to achieve compensation or absorption of the reactive power of the distribution network system, thereby improving the system power factor, reducing line losses, and improving power quality.
