Abstract

The utility model discloses a high-frequency and high-voltage solid rectifier transformer. The rectifier transformer comprises a ferrite magnetic core, a high-voltage ignition coil and a low-voltage ignition coil; the high-voltage ignition coil is solidified through epoxy resin vacuum encapsulation after a high-voltage winding is connected with a high-voltage rectifying silicon stack in series; the low-voltage ignition coil is solidified by a low-voltage winding solely through epoxy resin vacuum encapsulation; the high-voltage ignition coil and the low-voltage ignition coil are mounted on the same mast of the ferrite magnetic core; the high-voltage winding in the high-voltage ignition coil is solidified through epoxy resin vacuum encapsulation after three or more than three windings are connected in series; and heat radiation channels are reserved between the solidified adjacent windings. In the utility model, the heat radiation channels are additionally formed between the adjacent windings in the high-voltage ignition coil, so that the heat radiation channel between the ferrite magnetic core and the low-voltage ignition coil is shortened so as not to accumulate heat quantity, and the temperature rise of an entire transformer is small; and the magnetic core with big size needs not to be adopted, thereby improving the reliability of the transformer, prolonging the service life thereof, and reducing the manufacturing cost of the transformer.

Description

High-frequency and high-voltage solid rectifier transformer

Technical field

The utility model relates to the rectifier transformer technical field, specifically is a kind of high-frequency and high-voltage solid rectifier transformer that is used for the static fume cleaning equipment.

Technical background

Disclosed in the market 3KW is following, the high-frequency and high-voltage solid rectifier transformer of high pressure output 5～30KV, mainly be to solidify with epoxy resin or insulating varnish embedding by FERRITE CORE, low pressure bag, high voltage package, rectification silicon stack integral body to make, but because the restriction of high frequency high voltage transformer insulating material and manufacture craft, there are defectives such as leakage inductance is big, capacitance profile is big, cause the transformer temperature rise, be difficult to heat radiation, the epoxy resins insulation layer of rectifier transformer occurs aging, even the crack appears, will cause the high pressure winding breakdown and damage.Though and part high-frequency and high-voltage solid rectifier transformer has adopted the high-low pressure winding separately to solidify, and reserving certain heat dissipation channel between magnetic core and the low pressure winding and between low pressure winding and the high pressure winding, but owing to be subjected to the restriction of FERRITE CORE size, be difficult to be left to that enough heat dissipation channels prevent that the transformer internal heat from gathering and the damage that causes.And adopt bigger magnetic core size, tend to increase the production cost of transformer.

The utility model content

Technical problem to be solved in the utility model provides a kind of high-frequency and high-voltage solid rectifier transformer of good heat dissipation effect, can effectively solve the problem of the temperature rise of high-frequency and high-voltage solid rectifier transformer, heat radiation difficulty.

The utility model such as following technical scheme solve the problems of the technologies described above: the utility model high-frequency and high-voltage solid rectifier transformer comprises FERRITE CORE, high voltage package, the low pressure bag, described high voltage package is to make with epoxide resin vacuum embedding curing after being connected in series by high pressure winding and high-voltage rectification silicon stack, described high pressure winding is to connect the back by the windings in series more than three or three to be formed by epoxide resin vacuum curing, leave heat dissipation channel between the adjacent winding after the curing, the low pressure bag is to be solidified with the epoxide resin vacuum embedding separately by the low pressure winding to make, and described high voltage package and low pressure bag are installed on the same mast of FERRITE CORE.

The utility model is by setting up heat dissipation channel between the adjacent winding in high voltage package, the heat dissipation channel of FERRITE CORE and low pressure bag is shortened, heat can't gather, the temperature rise of transformer integral body is little, need not adopt the large scale magnetic core just can improve the reliability of transformer and increase the service life, and reduce the production cost of transformer.

Embodiment

As shown in drawings, rectifier transformer of the present utility model is made up of FERRITE CORE 1, high voltage package 3 and low pressure bag 2, high voltage package 3 is that the high pressure winding and the rectification silicon stack 4 that form with epoxy resin cure after being connected in series by three high pressure windings 6.1,6.2 and 6.3 adopt the method that the epoxide resin vacuum embeddings are solidified to make, and leaves the gap as heat dissipation channel 5.1 and 5.2 between the adjacent high pressure winding after wherein solidifying; Low pressure bag 2 is to be made with the method that the epoxy resin embedding is solidified separately by the low pressure winding, and low pressure bag 2 and high voltage package 3 are installed on the same mast of FERRITE CORE 1.

During making, after high pressure winding 6.1,6.2 and 6.3 is connected in series, with put into corresponding curing mold after rectification silicon stack 4 is connected, after adding epoxy resin 7 carries out vacuum solidification, after removing corresponding mould, obtaining high pressure winding and rectification silicon stack is the high voltage package 3 of one, between the adjacent high pressure winding on the high voltage package 3 heat dissipation channel 5.1 and 5.2 is arranged.

When high voltage package 3 and FERRITE CORE 1.1 and 1.2 and after 2 assemblings of low pressure bag finish, during transformer work, FERRITE CORE 1.1 and 1.2 and the heat of low pressure bag 2 except can be by gap 8 between magnetic core and the low pressure bag and 9 heat radiations of the gap between low pressure bag and the high voltage package, can also dispel the heat by the heat dissipation channel on the high voltage package 5.1 and 5.2, heat dissipation channel is shortened, and increased the area of dissipation of high voltage package, thereby realized the temperature rise of reduction transformer, improved the reliability of transformer and the purpose that increases the service life.

High pressure winding in the high voltage package of the present utility model also can be more than three, and the heat dissipation channel shape between adjacent high pressure winding also can have multiple shape,

The utility model does not limit the structure of the foregoing description, can adopt other structure yet.
