Technical Field

The utility model belongs to the technical field of get the electric transformer application, concretely relates to high voltage is got electric power source embedment transformer.

Background

A Transformer (Transformer) is a device that changes an alternating-current voltage by using the principle of electromagnetic induction, and main components are a primary coil, a secondary coil, and an iron core (magnetic core). The main functions are as follows: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), and the like, and can be classified into: power transformers and special transformers (furnace transformers, rectification transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers, reactors, mutual inductors, etc.).

The transformer has the primary purpose of ensuring the safety of people, and the main functions of the transformer are voltage reduction and isolation, wherein the voltage reduction is to reduce high voltage (such as 220V commercial power) to be within a safe voltage, and the isolation is also to isolate the voltage to ground of a live wire. The transformers in the market are also divided into a bare type transformer and a sealed type transformer, a silicon steel sheet of the bare type transformer is exposed outside, a coil only wraps two layers of adhesive tapes, insulation between a primary layer and a secondary layer is difficult to guarantee, an outer shell is exposed, and once electric leakage occurs, electric shock accidents are easy to cause.

Epoxy potting the transformer solves this problem very well, the transformer being encased in a plastic housing and impregnated with epoxy. The housing has no charged part at all, and the epoxy resin can penetrate into the gap of the transformer, the dielectric strength of the resin is much higher than that of air, 3000V can puncture 1mm of air, but tens of thousands of volts are needed to puncture 1mm of epoxy resin. The electrical strength of the encapsulated transformer is higher than that of a bare transformer by one grade, and encapsulation modes are also classified into normal-pressure encapsulation and vacuum encapsulation. Normal pressure embedment is exactly in pouring into the shell with epoxy under normal atmospheric pressure condition, and the vacuum embedment then needs professional equipment to pour into the shell with epoxy under vacuum environment, and relative normal pressure embedment, the inside air can be taken out in the vacuum embedment, and the finished product does not have the bubble.

The existing high-voltage power-taking power supply encapsulating transformer is unreasonable in design, low in product production efficiency (inconvenient to assemble), short in service life, poor in safety and quality stability and the like.

Therefore, based on the above problem, the utility model provides a high pressure is got electric power source embedment transformer.
