Abstract

The invention discloses a blocking block-based cross interconnecting box, which comprises a box body, three-phase grounding wire tubes, wiring rods, three-phase common bolts, insulating plates and interconnecting rods. An external cable can enter the back of the box body through a wire tube, the tail end of the A-phase wire is connected with the B-phase bolt arranged on the first insulating platethrough the A-phase protection layer protector, and the B-phase bolt of the first insulating plate is connected with the head end of the B-phase wire; the tail end of the B-phase wire is connected with the C-phase bolt arranged on the first insulating plate through the B-phase protection layer protector, and the C-phase bolt of the first insulating plate is connected with the head end of the C-phase wire; and the tail end of the C-phase wire is connected with the A-phase bolt arranged on the first insulating plate through the C-phase protection layer protector, and the A-phase bolt of the first insulating plate is connected with the head end of the A-phase wire. Through arranging different shapes of blocking blocks on the cross interconnecting box, the positions and the directions of the interconnecting rods arranged in the box body can be easily recognized by an operator, misoperation can be prevented, and the safety efficiency is greatly improved.

Description

technical field [0001] The present invention relates to the field of electric power, and more particularly, to a cross-connection box based on a barrier block. Background technique [0002] At present, the power grid is connected by a cross-connect box. The tail of phase A is connected to the head of phase B, the tail of phase B is connected to the head of phase C, and the tail of phase C is connected to the head of phase A, so that the current of the cable core can be connected. The induced currents to the shielding layer cancel each other out. However, in actual operation, operators often cannot distinguish the terminals or bolts corresponding to A-phase, B-phase and C-phase. If they are connected incorrectly, the equipment will be damaged. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cross-connection box based on a barrier block. [0004] For solving the above-mentioned technical ...
