Modularized assembly type power supply small transformer convenient to maintain

Abstract

The invention discloses a modular assembly type convenient-to-maintain power supply small transformer which comprises a first upper component and a second upper component, a first ceramic heat dissipation block is detachably arranged between the first upper component and the second upper component, an upper positioning hole is formed in the bottom of the first ceramic heat dissipation block, and a lower positioning hole is formed in the bottom of the second ceramic heat dissipation block. A magnetic core is detachably arranged in the upper positioning hole, a coil is arranged on the outer surface of the magnetic core in a sleeved mode, a first lower component is detachably arranged below the second upper component, a second lower component is detachably arranged on the first upper component, and the first lower component and the second lower component are detachably arranged on the second upper component. And a second ceramic heat dissipation block is detachably arranged between the second lower component and the first lower component. The invention relates to the technical field of transformers. According to the modular assembly type power supply small-sized transformer convenient to maintain, through an assembly type structure, when one group of magnetic cores and coils are damaged, the magnetic cores and the coils can be disassembled and maintained, and the practicability and the safety are improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a modularized assembled small-sized power transformer for easy maintenance. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). In electrical equipment and wireless circuits, it is often used for voltage reduction, impedance matching, and safety isolation. In the generator, whether the coil moves through the magnetic field or the magnetic field moves through the fixed coil, an electric potential can be induced in the coil, which is widely used in industry, agriculture, transportation, urban communities and other fields. [0003] Among them, small transformers mainly refer to single-phase transformers below 20 kV·A and three-phase transformers below 50 kV·A. They are characterized by small size, low co...
