DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.
[0018] A quick connection and protection box for 10kV overhead line diversion cable, as Figures 1 to 3As shown, it includes a box body 1, the upper part of the box body 1 is hinged with a box door 2 through a hydraulic rod 8, and the lower part of the box body 1 is provided with an inclined wire groove 7 to facilitate the entry and exit of wires.
[0019] The box body 1 is provided with a card slot 11 for carding with the box door 2. The inner side of the card slot 11 is provided with a sealing rubber ring 10 for sealing, which can realize the protection against electric shock and rainproof.
[0020] The box body 1 corresponding to the box door 2 is provided with reinforcing plates 3 arranged in an upper and lower staggered manner. Six insulating pillars 4 are installed on the upper reinforcing plate 3 , and the insulating pillars 4 are connected to the copper bus 5 .
[0021] Six insulating supports 4 are installed on the back plate of the box corresponding to the upper reinforcing plate 3 to prevent the wiring row from loosening due to frequent operations during wiring.
[0022] Bolt assemblies are installed on the upper and lower ends of the copper busbars 5 respectively to facilitate quick wiring. The tops of the three copper busbars 5 on the left are connected to the ABC three-phase incoming lines 15 in sequence, and the tops of the three copper busbars 5 on the right are connected to the ABC three-phase outgoing lines 16 in sequence.
[0023] The top ends of the ABC three-phase incoming line 15 and the ABC three-phase outgoing line 16 are respectively installed with umbrella-shaped insulating sleeves 9 for insulation protection.
[0024] A grounding terminal block 6 is installed on the lower reinforcement plate 3 through a bolt assembly. The grounding terminal block 6 can provide a low-impedance grounding path to ensure that when the equipment leaks or fails, the current can quickly flow into the ground through the grounding terminal block, thereby reducing the risk of electric shock and the possibility of equipment damage.
[0025] An insulating plate 12 is installed at the top of the wire duct 7, and three incoming wire ducts 13 and three outgoing wire ducts 14 are provided on the insulating plate 12 for the overhead line to pass through. Elastic sealing rings are respectively provided inside the incoming wire duct 13 and the outgoing wire duct 14 to ensure the smooth passage of the line while preventing external animals from drilling into it.

[0027] When wiring, the line is passed through the wire trough 7 into the box body 1. Since the bottom of the wire trough 7 is a slope with a certain angle, it can effectively avoid the large stress caused by the small radius when the cable is connected.
[0028] Then, open the box door 2 and prop it up at a certain angle through the hydraulic rod 8 to facilitate wiring into the box body. Use the bolt assembly to connect the lines inserted into the box body 1 in sequence according to the line operation situation.
[0029] After the wiring is completed, loosen the hydraulic rod 8, close the box door, ensure that the box door 2 is clamped into the slot between the box body 1 and the sealing rubber ring 10 to ensure the sealing performance and prevent rain and electric shock.
[0030] The utility model provides a quick wiring and protection box for a 10kV overhead line drainage cable. By setting the ground of the wire groove as an inclined plane with a certain angle, the smoothness of the line inlet and outlet during wiring is ensured, which is convenient for wiring. And by setting an openable box door, the connection and fastening of the line are completed, which is convenient and efficient. The cooperation of the insulating board, the sealing rubber ring and the umbrella-shaped insulating sleeve is arranged inside the wiring box body, which improves the sealing effect, the insulation and protection effects, avoids the phenomenon of electric shock when the wire comes out, and ensures the safety.
