Description

Technical Field

[0001] The utility model belongs to the technical field of transformers, and in particular relates to a transformer lead structure. Background Art

[0002] The main functions of a transformer include voltage conversion, current conversion, impedance conversion, isolation and voltage regulation. It can convert the AC voltage and current of one system into the voltage and current of another system. Usually, the values ​​of these currents and voltages are different. Therefore, transformers play a key role in power systems. For example, in the process of power transmission, energy loss is reduced by increasing the voltage, or when distributing electric energy, the voltage is reduced to meet the needs of different users. The line ends of the transformer are generally divided into two types, namely low-voltage terminals and high-voltage bushings. There are generally four low-voltage terminals and three high-voltage bushings. Due to the importance of transformers, their use scenarios are gradually increasing.

[0003] In the existing technology, in order to protect the wires from being pulled during maintenance and damaging the port connection, a terminal protection device is usually used. However, since the connection of the high-voltage bushing is generally a switch, it is generally located above the transformer and fixed between two wire poles, and the low-voltage terminal is generally connected to a distribution box. Due to the differences in craftsmanship and material selection in various regions, the location of the distribution box is more flexible. Therefore, the wires at the low-voltage terminal require higher flexibility in layout, and the grounding wire needs to be set separately. The existing protection device cannot meet the requirements of protecting the terminal while flexibly arranging the direction to reduce the overall distortion of the wire and extend the service life of the wire.

Through the connection of the connecting rod, the direction of the movable ball is synchronously adjusted, and the wire outlet hole is perpendicular to the low-voltage terminal, which is convenient for the wire to pass through and fix the wire. Then the wire is passed through the wire outlet slot into the inside of the wire outlet hole, and then passed through the wire outlet hole from another wire outlet slot.

[0022] The outer wall of the slide rail 7 is slidably connected with a protection component, which is used to protect the connection between the wire and the low-voltage terminal 2 from being pulled. The protection component includes a slider 12 slidably connected to the outer wall of the slide rail 7, and the outer wall of the slider 12 is fixedly connected with a positioning cylinder 14. The outer wall of the positioning cylinder 14 is provided with evenly distributed wire outlet grooves 16. The interior of the positioning cylinder 14 is rotatably connected with evenly distributed movable balls 15, and the movable balls 15 correspond to the positions of the wire outlet grooves 16.
