Description

Technical Field

[0002] As an important electrical equipment in the power system, the transformer is widely used in the fields of electric energy metering, relay protection, system monitoring, etc. In the installation, commissioning and maintenance of the transformer, wiring is a crucial task. However, the wiring of the transformer currently relies mainly on manual operation, which has the following problems:

[0003] 1. Manual wiring is inefficient. In the traditional transformer wiring process, workers need to rely on experience and visual observation to determine the wiring position, and then perform manual wiring. This process is not only time-consuming, but also easily affected by human factors, such as fatigue and lack of concentration, resulting in low wiring efficiency. For some complex transformer systems, it may be necessary to connect multiple terminals at the same time, which further increases the difficulty and workload of manual wiring, seriously affecting the work progress.

[0004] 2. It is difficult to calibrate the position of the wire core. During the manual wiring process, the position of the wire core is often difficult to accurately control, and problems such as wire core bending and offset are prone to occur. This not only affects the aesthetics of the wiring, but may also cause problems such as poor contact and increased resistance, affecting the performance of the transformer. At present, the correction of the wire core position mainly relies on manual adjustment, which is inefficient and difficult to guarantee accuracy. Some simple tools such as tweezers and pliers are also difficult to meet the complex needs of wire core correction.

[0005] In summary, there is an urgent need for a transformer auxiliary wiring device to improve the wiring efficiency, accuracy and safety of the transformer, reduce labor costs and safety risks, and ensure the stable operation and measurement accuracy of the transformer. Summary of the invention

8. A transformer test wiring auxiliary device according to any one of claims 1 to 6, characterized in that: A first clamping groove (11) and a second clamping groove (11.1) matching the electric wire (1) are respectively arranged between the first clamping block (9) and the second clamping block (12); and anti-slip grooves are distributed on the walls of the first clamping groove (11) and the second clamping groove (11.1).

9. A transformer test wiring auxiliary device according to claim 8, characterized in that: The conduction assembly comprises a first connection block (10) and a pressing block (36), wherein the first connection block (10) is connected to the bottom wall of the cavity, and the pressing block (36) is connected to the upper surface of the first connection block (10); A plug-in assembly (37) is provided between the first connecting block (10) and the pressing block (36), and the plug-in assembly (37) is a spring sheet (40) abutting against each other. When the core of the electric wire (1) is conveyed to the plug-in assembly (37), the core of the electric wire (1) is clamped and electrically connected by the spring sheets (40) abutting against each other.

10. A transformer test wiring auxiliary device according to claim 9, characterized in that: The conduction component further comprises a sensing block (38) and a sensor (39); the spring sheet (40) is an arc-shaped spring sheet; the sensing blocks (38) are arranged at both ends of the spring sheet (40); and the arc-shaped ends of the spring sheet (40) abut against the adjacent sensing blocks (38); When the core of the electric wire (1) enters between the abutting spring sheets (40), the arc-shaped end of the spring sheet (40) squeezes the sensing block (38). When the sensor (39) detects the squeezing stress, the sensor (39) transmits an electrical signal to an external control component (4). The control component (4) is electrically connected to the guide component (8) and the clamping component.
