Description

Technical Field

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

[0002] A transformer is an electrical device used to change the voltage of an alternating current. It mainly uses the principle of electromagnetic induction to increase or decrease the voltage of an alternating current. The transformer is mainly composed of an iron core and a coil. The iron core is usually made of multiple layers of silicon steel sheets stacked together to reduce hysteresis loss and eddy current loss. The coil is divided into a high-voltage coil and a low-voltage coil, which are wound around different parts of the iron core. When the alternating current passes through the high-voltage coil, an alternating magnetic field is generated in the iron core. This alternating magnetic field will generate an induced electromotive force in the low-voltage coil, thereby achieving a change in voltage. There is no direct electrical connection between the high-voltage coil and the low-voltage coil of the transformer, but energy is transferred through the magnetic field, so it has good electrical isolation performance. Transformers are widely used in power systems, communication systems, automatic control systems and other fields, and play a key role in the transmission and distribution of electric energy. It can reduce the high voltage generated by the power plant to a level suitable for users, and at the same time it can also increase the low voltage at the user end to a level suitable for long-distance transmission. In addition, the transformer can also output multiple voltages to meet the power supply needs of different equipment. In short, the transformer is an indispensable and important equipment in the modern power system.

[0003] After searching, the Chinese patent document announcement number is: CN212810010U. This utility model discloses a transformer output line structure, including an iron core, 3 windings, an insulator, a first L-shaped steel, a second L-shaped steel, an insulating plate, a support plate, an output copper bar, a lap copper bar, and a high-voltage terminal. The first L-shaped steel and the second L-shaped steel are fixed by bolts, thereby clamping the insulating plate and the iron core. The straight output copper bar is led out from the winding, passes through the insulating plate and is connected to the high-voltage terminal through the lap copper bar. The straight output copper bar does not need to be bent, and the output copper bar is isolated from the iron core by the insulating plate, which reduces the manufacturing cost and improves the manufacturing efficiency while not reducing the safety performance. The high-voltage terminal is fixed on the support plate to form an integrated structure. The user can directly fix the cable to the high-voltage terminal. Since the wiring space of the high-voltage terminal is large, the convenience of user wiring is improved. The device has a simple structure, effectively reduces the overall manufacturing cost, and improves the manufacturing efficiency.

[0004] Although the above patent mentioned in the specification that "the transformer output line structure, the first L-shaped steel and the second L-shaped steel are fixed by bolts, thereby clamping the insulating plate and the iron core, and the straight output copper busbar is led out from the winding, passes through the insulating plate and is connected to the high-voltage terminal through the overlapping copper busbar. The straight output copper busbar does not need to be bent, and the output copper busbar is isolated from the iron core by the insulating plate, which reduces the manufacturing cost and improves the manufacturing efficiency while not reducing the safety performance. The high-voltage terminal is fixed on the support plate to form an integrated structure. The user can directly fix the cable to the high-voltage terminal. Since the wiring space of the high-voltage terminal is large, the convenience of user wiring is improved. The device has a simple structure, effectively reduces the overall manufacturing cost, and improves manufacturing efficiency", but it is impossible to achieve stable clamping and limiting of the cable, and it is impossible to effectively prevent the cable from being damaged due to excessive clamping force. Therefore, in view of the above shortcomings, a transformer output line structure is proposed. Utility Model Content

[0031] Working principle: When the cable needs to be connected or repaired, the plate 29 can be pulled first, which can drive the column 24 and the sliding plate 23 to move.

At this time, the cable can be fixed and limited by means of the arc plate 14. With the displacement of the arc plate 14, the sliding rod 17 will be displaced, and then the spring 18 will be compressed and rebounded. At this time, the elastic force of the spring 18 can be used to buffer the cable clamping force, thereby preventing damage to the cable.
