Multidirectional adjustable load switch temporary bracket device

Abstract

The invention relates to a multidirectional adjustable load switch temporary bracket device comprising a pair of switch clamping pieces, a pair of switch support frames, a pair of iron core clamps, a pair of vertical adjustment plates, and a pair of transverse adjustment plates. A first sliding groove is arranged on each vertical adjustment plate, and the vertical adjustment plates are fixed by a first bolt after moving via the first sliding grooves with respect to the switch support frames; a vertical second sliding groove is arranged at one end of each transverse adjustment plate, and the transverse adjustment plates can be fixed by a second bolt after moving upwards and downwards along the side walls of the vertical adjustment plates; the transverse adjustment plates are provided with transversely arranged third sliding grooves, and the iron core clamps can be fixed by a third bolt after moving along the third sliding grooves of the transverse adjustment plates. According to the device provided by the invention, the distance L1 between the iron core clamps is adjustable, the positioning height H1 of the switch is adjustable, and the distance L2 between the switch center and the front end of the iron core clamps is adjustable. The multidirectional adjustable load switch temporary bracket device can be adjusted to adapt to different transformer load switch positioning sizes.

Description

technical field [0001] The invention relates to a temporary bracket device for an on-load switch, in particular to a multi-directional adjustable temporary bracket device for an on-load switch. Background technique [0002] When the on-load switch is connected to make lead wires, the switch needs to be temporarily supported by a temporary bracket, and the temporary bracket is supported until the transformer is disassembled at the final assembly stage. [0003] At present, the bell-type on-load switching transformer with a capacity of 20,000kVA and below and a voltage level of 110kV, because the height of the transformer body is short, the switch voltage level required is high, and the height of the switch exceeds the height of the body. When the lead wire is connected to the switch, The switch needs to be fixed at the required height with a temporary bracket, and the temporary bracket can only be removed after the lead wire is completed, the body is dry, and the test is pass...

AI Technical Summary

Problems solved by technology

With this type of temporary bracket device, the inner distance L1 of the iron core clamp cannot be adjusted, the switch positioning height H1 cannot be adjusted, and the distance L2 between the switch center and the front end of the iron core clamp cannot be adjusted.

[0005] The defect of the above-mentioned temporary bracket device is: because the parameters of each transformer are different, the design size is also different, so when the lead wire is connected to the switch, each switch needs to be equipped with a temporary bracket. It cannot be used in subsequent products, which greatly wastes resources such as materials and labor
