Description

technical field [0001] The invention relates to the technical field of high-voltage overhaul and maintenance, in particular to a secondary wiring device. Background technique [0002] At present, as the number of substations increases year by year, the number of 10kV high-voltage switchgears in substations is also increasing, and the types of products are becoming more and more complicated. In the daily maintenance of high-voltage switchgear, it is necessary to carry out mechanical characteristic tests. The contents of mechanical characteristic tests generally include the following contents: circuit breaker closing time, opening time, reclosing time test, opening and closing synchronism Test, low voltage opening, closing reliability test, etc. One of the key points of the mechanical characteristic test is the secondary wiring part of the high-voltage switchgear. However, the secondary wiring part of the existing high-voltage switchgear generally has a small space and a larg...

Problems solved by technology

One of the key points of the mechanical characteristic test is the secondary wiring part of the high-voltage switchgear. However, the secondary wiring part of the existing high-voltage switchgear generally has a small space and a large number of wiring. Substation maintenance personnel are prone to make mistakes in the busy schedule, and wrong wiring may occur. Damage to key equipment such as opening and closing coils, and when it is necessary to test the mechanical characteristics of multiple high-voltage switchgears, repeated wiring for a long time will reduce work efficiency and increase safety risks
