Problems solved by technology

[0002] In the current construction of substations, the secondary wiring of the protective screen is a relatively time-consuming task. Since the secondary wiring from electrical equipment such as circuit breakers and transformers to the control room is required, it is generally concentrated at the rear of the protective screen, and then connected to the protective screen. Butt connection of terminals, because there is no special tool for wiring, generally rely on the operator to break the secondary wiring into an arc shape, and then make a fixed connection, but due to the limited construction time, it is difficult to process all the secondary wiring shapes Unified, this will lead to a very chaotic wiring pattern at the rear of the protective screen, which is not conducive to the maintenance and repair of the protective screen in the future. More importantly, there are many terminals on the secondary side of the transformer, and the wires are easy to be fixed and not firm during the wiring process. After falling off, it is easy to cause the power supply failure of the substation

Abstract

The invention discloses a substation secondary wire straightening and bending device and a wire fixing tightness commissioning method. The device comprises a cylinder, wherein supporting legs which are movably connected are arranged at the two ends of the cylinder and a magnet is arranged at one end of each supporting leg. Not only can substation secondary wires be straightened and bent in a batch, but also automatic bending can be realized, the bending tidiness and efficiency are high, the maintenance of a protection screen in future is facilitated, and more importantly, whether the substation secondary wires are firm or not can be conveniently detected.
