Abstract

The utility model discloses a voltage transformer, including transformer, shell, once lead wire and secondary lead wire, the transformer includes square iron core, primary winding and secondary winding, and primary winding, secondary winding do not suit in the both sides of square iron core, and the transformer passes through the pouring of insulating casting glue and pours into a mould in the shell that insulating material made, and square iron core is ungrounded, and the one end of once leading wire, the one end of secondary lead wire are connected with primary winding, secondary winding respectively, and the other end all extends to outside the shell, and a lead wire, secondary lead wire all adopt insulated cable. The utility model saves the complex process of mold filling and sealing and curing, and saves time and labor in processing; the insulation margin is increased, the creepage distance and the space distance are greatly increased, the volume can be greatly reduced, and the cost is reduced.

Description

Voltage transformer
Technical Field
The utility model relates to a mutual-inductor technical field especially relates to a voltage transformer.
Background
Most of the traditional voltage transformers adopt a die filling and sealing process, and the manufacturing process is complex, labor-consuming and time-consuming. The iron core is grounded, the insulation and voltage resistance is born by an insulated coil framework, and the insulation margin is not large. The primary and secondary leads are made of conductive materials such as screws, so that the charged metal part is exposed, and the creepage distance can be ensured only by increasing the volume, thereby increasing the cost.
Disclosure of Invention
The utility model aims at providing a low-cost voltage transformer to solve the problems of complex processing technique, labor and time consumption existing in the traditional voltage transformer; insulation margin is not large: large volume, high cost and the like.
In order to solve the above problem, the utility model discloses the technical scheme who adopts as follows:
the utility model provides a voltage transformer, includes transformer, shell, primary lead and secondary lead, the transformer includes mouth font iron core, primary winding and secondary winding, and primary winding, secondary winding suit are respectively in the both sides of mouth font iron core, the transformer passes through the insulating casting glue pouring in the shell that insulating material made, mouth font iron core is ungrounded, the one end and the primary winding of primary lead are connected, and the one end and the secondary winding of secondary lead are connected, the other end of primary lead and secondary lead all extends to outside the shell, primary lead and secondary lead all adopt insulated cable.
The utility model has the advantages that: the complex processes of mold encapsulation and solidification are omitted, and the processing is time-saving and labor-saving. Because the iron core is not grounded, the potential is in a suspension state, the insulation and voltage resistance between the primary lead and the secondary lead is born by two insulation coil frameworks in the primary winding and the secondary winding, and the insulation margin is increased; because the first lead and the secondary lead both adopt insulated cables and have no exposed conductive parts, the creepage distance and the space distance are greatly increased, the volume can be greatly reduced, and the cost is reduced.
Drawings
Fig. 1 is a schematic structural diagram of a voltage transformer of the present invention;
fig. 2 is a schematic diagram of a left side structure of a transformer in a voltage transformer according to the present invention;
wherein: 1. a housing; 2. a square iron core; 3. a primary winding; 4. a secondary winding; 5. a primary lead; 6. secondary lead, 7, insulating pouring sealant.
Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
Example one
As shown in fig. 1, a voltage transformer comprises a transformer, a housing 1, a primary lead 5 and a secondary lead 6, wherein the transformer comprises a square iron core 2, a primary winding 3 and a secondary winding 4, the primary winding 3 and the secondary winding 4 are respectively sleeved on two sides of the square iron core 2, the iron core 2 is ungrounded, the transformer is poured in the housing 1 made of an insulating material through an insulating pouring sealant 7, and the primary lead 5 and the secondary lead 6 are respectively connected with the primary winding 3 and the secondary winding 4 and extend out of the housing 1. Wherein, the first and the second leads 5 and 6 are insulated cables.
The primary winding 3 and the secondary winding 4 can adopt windings with frameworks or windings without tires. When the core-stripping winding is installed, the distance between the core and the square iron core 2 is kept, the primary winding 3, the secondary winding 4 and the square iron core 2 are filled with insulating pouring sealant 7, and the insulating pouring sealant 7 bears the insulation and pressure resistance.
