A common mode transformer and its installation method

Abstract

The application relates to a common-mode transformer and its installation method, and relates to the field of transformer equipment to solve the problem that the coil on the magnetic core is not easy to install and disassemble. It includes two metal blocks and a coil arranged between the two metal blocks , the middle part of the coil is equipped with a mounting component, the coil is fixedly connected between two metal blocks through the mounting component, the mounting component includes a metal core and a metal ring sleeved outside the metal core, and the metal ring and the metal core are slidingly connected The coil is arranged outside the metal ring, the inner wall of the coil is attached to the outer wall of the metal core, and the two ends of the metal core are detachably connected to the two metal blocks. The application has the advantages of being convenient to install or remove the metal core between two metal blocks, and at the same time, the metal ring that winds the coil can be installed on or removed from the metal core, so that the transformer can be improved. The production efficiency is high, and it is convenient to recycle the coil.

Description

technical field [0001] The present application relates to the field of transformer equipment, in particular to a common-mode transformer and an installation method thereof. Background technique [0002] With the rapid development of my country's national economy, the demand for electricity is also increasing. As the main equipment in the power transmission and transformation system, transformers have also developed rapidly. A transformer is a method that uses the principle of electromagnetic induction to convert one level of voltage and current into another level of voltage and current at the same frequency and transmit electric energy between two or more coils. The main component of the transformer is the primary coil , secondary coil and core. [0003] The traditional transformer usually winds the primary coil 1 and the secondary coil 2 around the outside of the iron core 3 (such as figure 1 ), in order to reduce the loss of electric energy, the material of the coil is u...

Problems solved by technology

[0003] The traditional transformer usually winds the primary coil 1 and the secondary coil 2 around the outside of the iron core 3 (such as figure 1 ), in order to reduce the loss of electric energy, the material of the coil is usually made of copper, but the iron core is usually a whole, which is inconvenient when winding the coil, and there is a problem of uneven winding, which leads to poor magnetic flux effect, and the transformer should be replaced At the same time, the coil wound on the iron core is not easy to remove and recycle, resulting in waste of resources and increasing the production cost of the transformer
