In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: a novel contact box of a medium-voltage power distribution cabinet comprises a contact box, wherein a pre-buried conductive piece is inserted into the contact box, the pre-buried conductive piece is provided with a separable copper busbar in a horizontal state, and the end face of the contact box is provided with at least one pair of contact ventilation holes;

the upper end of the pre-buried conductive piece extends out of the contact box, and the width of the bottom of the pre-buried conductive piece is slightly smaller than that of the end part of the contact box.

Preferably, the pre-buried conductive piece is of an inverted T-shaped structure.

Preferably, at least four mounting holes are formed in the embedded conductive piece.

Preferably, the bottom of the contact box is provided with a base structure; the base structure supports the contact box.

Preferably, the base structure is provided with a plurality of fixing holes; the plurality of fixing holes mount the base structure.

Preferably, the longitudinal section of the contact box is stepped, and the cross-sectional area is reduced from bottom to top.

Preferably, the contact box is a box body made of epoxy resin materials.

Advantageous effects

The utility model provides a novel contact box of medium voltage distribution cabinet. The method has the following beneficial effects:

1. the on-site power distribution room cabinet combining and busbar screen connecting work is simpler and easier to operate.

2. The working hours and raw materials can be saved in the overhaul process of the power distribution equipment, and the use is more convenient and faster;

3. the contact box is made of epoxy resin material, and the umbrella group has a large creepage distance and is longer.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution:

example (b): referring to fig. 4-5, in the original design of the conventional first-generation KYN88-12 type medium voltage distribution cabinet, the contact box uses the horizontal busbar on the top of the cabinet as a circuit breaker plugging point, the research and development design of the longitudinal isolation circuit breaker has an external force generated by shaking the contact box left and right when the horizontal busbar is plugged, the horizontal busbar is fixedly connected with the contact box through two bolts, and the horizontal busbar is fragile because the epoxy resin contact box does not have extensibility when the contact and the connection are performed.

In view of the above problems, the technical solution is provided, which specifically comprises:

referring to fig. 1-3, the body is a contact box 1, a pre-buried conductive piece 2 is inserted into the contact box 1, the pre-buried conductive piece 2 is provided with a separable horizontal copper busbar 3, and at least one pair of contact ventilation holes 4 are formed in the end surface of the contact box 1;

the upper end of the pre-buried conductive piece 2 extends out of the contact box 1, and the width of the bottom of the pre-buried conductive piece 2 is slightly smaller than that of the end part of the contact box 1.

It should be noted that, this technical scheme will pre-buried conductive piece 2 arrange in contact box 1 to stretch out contact box 1 with pre-buried conductive piece 2's upper end, thereby utilize the pre-buried conductive piece 2 who stretches out contact box 1 part to install copper mother board 3.
