Abstract

The invention provides a 35kV and 110kV transformer routine test wiring switch box which is characterized in that: a switch box (1) is a cuboid, the top of the switch box (1) is provided with A group (2), B group (3), C group (4), D group (5) and E group (6) of connector plugs which are in paired conduction with five groups of connector plugs at a side part, the side face of the switch box (1) is provided with a handle (7), the switch box (1) is made of an insulating material, and the switch box (1) is made of a resin material. The 35kV and 110kV transformer routine test wiring switch box has the advantages that the frequency of climbing a main transformer is reduced, the time of working on the transformer is reduced, the working efficiency and safety are improved, after using the switch box, the dangerous work at the top of the transformer is transferred to the ground to complete, the working efficiency is improved, and the risk of the work is reduced.

Description

[0001] 1. Technical field [0002] The invention relates to the field of electric power technology, in particular to a routine test wiring conversion box for 35kV and 110kV transformers. [0003] 2. Background technology [0004] Transformers that operate under high load for a long time are prone to failures. Common transformer failures include aging of internal insulation and inter-turn short circuit of windings. State Grid Corporation of China Enterprise Standard Q / GDW1168-2013 "Test Regulations for Condition Maintenance of Power Transmission and Transformation Equipment" stipulates that 110kV and 35kV transformers need to be regularly tested for high voltage. When carrying out high-voltage tests on transformers, it is necessary to connect the lead wires of the test instrument to the bushing pile heads on each side of the transformer, and change the connection mode of the bushing pile heads on each side according to different test items. At present, the traditional test meth...
