Description

Combined transformer

Technical Field

The utility model relates to a transformer specifically is a modular transformer.

Background

The transformer is a device for changing alternating voltage by using the principle of electromagnetic induction, and main components are a primary coil, a secondary coil and an iron core. The main functions are as follows: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization, and the like. According to the application, the method can be divided into: power transformers and special transformers. The circuit symbol is usually T as the beginning of the number, for example, T01, T201, etc., and in electrical equipment and wireless circuits, transformers are usually used for voltage raising and lowering, impedance matching, safety isolation, etc. The combined transformer is one kind of transformer, and the fuse, multi-station ring network load switch and non-excitation voltage regulating tap switch of the combined transformer are installed inside the transformer oil tank as the parts of the transformer, and the fuse or the operation load switch is easy to replace outside the oil tank to change the operation condition of the transformer. The high-voltage side is supplied with electric energy by an elbow cable which can be plugged and unplugged with a load, a low-voltage wire outlet bin is additionally arranged outside the oil tank, and a space is arranged in the bin and can be additionally provided with a protection device and a measuring instrument according to requirements. All charged parts are in the box, and no exposed charged part exists. Since the main components are all in the tank, we call it a combined transformer, not a box substation. But the combined transformer also has the function of a box substation. Six cable sockets are arranged on the high-voltage side, so that the transformer can be connected into a ring network power supply system, and the ring network power supply system and the cabinet type ring net cage or the cable branch box form a ring network power supply system. Therefore, the combined transformer, the pedestal transformer or the American box transformer for short refer to the same product, and the main body is the transformer, not the transformer substation.

However, the conventional combined transformer is integrally connected, and when the transformer is used and installed, the whole transformer is installed, and the transformer is not easy to install in a narrow space due to the large volume. To this end, we propose a combined transformer.
