Description

Technical Field

[0001] This utility model relates to the technical field of combined high-power transformers, and in particular to a combined high-power transformer. Background Technology

[0002] A modular high-power transformer is an electrical device that combines multiple transformer units through modular design to achieve high-power electrical energy conversion, transmission and distribution. It is usually composed of multiple independent transformer modules, connection components, cooling system, control system and other parts, and the number of modules can be flexibly combined according to actual power requirements.

[0003] With the development of the times, electricity has become an indispensable part of people's lives. With the continuous advancement of urbanization in my country, the use of transformers is increasing. Transformers are used to provide power to high-rise residential communities, office buildings, hospitals, hotels and other places. A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation and voltage stabilization. Transformers can convert electrical energy into a high voltage and low current form and then convert it back, thus greatly reducing the loss of electrical energy during transmission.

[0004] The existing patent (publication number: CN215265813U) includes a transformer protective shell. One side of the inner wall of the transformer protective shell is fixedly connected to one end of a fixing rod, and the other end of the fixing rod is fixedly connected to one side of the outer surface of a fixing ring. The inner wall of the fixing ring is fixedly sleeved to the outer surface of a dual-axis motor. One end of the dual-axis motor is fixedly connected to one end of a rotating rod, and the outer surface of the other end of the rotating rod is fixedly sleeved to the inner wall of a fan. This protective device for the transformer mounts the transformer body on the top outer surface of a mounting plate via a mounting bracket. The bottom of the mounting plate is fixedly connected to a spring hole at the bottom of the inner wall of the transformer protective shell via a spring. This reduces the vibration of the transformer during operation and prevents the internal components of the transformer from loosening due to vibration. It solves the problem that the transformer vibrates during operation, and prolonged vibration may cause the internal components of the transformer to loosen and the wiring to easily fall off.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing high-power transformers are enormous in size and weight, making transportation and installation difficult. They typically need to be broken down into multiple smaller transformers. However, when assembling multiple smaller transformers, steps such as circuit connection and current distribution are time-consuming and labor-intensive. Furthermore, no other auxiliary effects can be achieved during the actual assembly of multiple smaller transformers, resulting in insufficient practicality.

[0006] Therefore, a combined high-power transformer is proposed. Utility Model Content

Next, multiple small-power transformers 11 are connected using the connector 13 and cable connecting rod 14. Parallel connection and current balance distribution are achieved through the parallel module 15 and the zigzag wiring 17. The connecting frame 3 connects multiple small-power transformers 11 into a whole, enhancing structural stability. During equipment operation… The iron core 12 and windings convert electrical energy, the silicon steel sheet 16 reduces iron loss, and the central control unit 22 receives monitoring data from the temperature sensor 27, current sensor 28 and voltage sensor 29.
