Novel power transfer device for switchgear

Abstract

The invention discloses a novel power transfer device for switchgear. The power transfer device comprises a power arm female head, a power arm male head and a hexagonal shaft, wherein the head parts of the power arm female head and the power arm male head are connected through a connecting shaft; the side part of the tail part of the power arm female head is provided with a convex strip; the side part of the tail part of the power arm male head corresponding to the convex strip is provided with a groove; the convex strip is inserted into the groove; the tail part of the power arm female head is provided with a first hexagonal through hole, and the tail part of the power arm male head is provided with a second hexagonal through hole; and the hexagonal shaft penetrates through the first hexagonal through hole and the second hexagonal through hole respectively, so that the power arm female head and the power arm male head are connected together. According to the power transfer device for switchgear, the tail parts of the power arm female head and the power arm male head are also connected into a whole body through matching of the convex strip and the groove; and thus, synchronous transfer of power can be guaranteed.

Description

technical field [0001] The invention relates to an improvement of a power transmission device, in particular to a new type of power transmission device for switchgear with good power synchronous transmission performance. Background technique [0002] Switchgear is a general term for high-voltage distribution cabinets, generators, transformers, power lines, circuit breakers, low-voltage switch cabinets, switchboards, switch boxes, control boxes and other power distribution equipment in the power system. Power transmission devices are all arranged in the switchgear, and the power transmission devices of the prior art, such as the attached figure 1 As shown, it includes a power arm female head 1, a power arm male head 2, and a hexagonal shaft 4; the heads of the power arm female head 1 and the power arm male head 2 are connected by a connecting shaft 3; the power arm female head 1, The tail of the power arm male head 2 is respectively provided with hexagonal through holes (not...

Problems solved by technology

Power transmission devices are all arranged in the switchgear, and the power transmission devices of the prior art, such as the attached figure 1 As shown, it includes a power arm female head 1, a power arm male head 2, and a hexagonal shaft 4; the heads of the power arm female head 1 and the power arm male head 2 are connected by a connecting shaft 3; the power arm female head 1, The tail of the power arm male head 2 is respectively provided with hexagonal through holes (not shown); the hexagonal shaft 4 passes through the hexagonal through holes of the power arm female head 1 and the power arm male head 1 respectively, so that the power arm female head 1. The male head 1 of the power arm is connected together; the power transmission device of this structure has a gap between the hexagonal shaft 4 and the hexagonal through hole at the tail of the female head 1 of the power arm and the male head 1 of the power arm, so that the power transmission is synchronized It is poor, and cannot fully guarantee the synchronization of the three-phase power on and off of the switchgear, so that the corresponding position can only be guaranteed by changing the corresponding position under the premise of different phases in the test.
