Abstract

This indoor semi-enclosed single-phase voltage transformer relates to a voltage transformer with an epoxy resin cast semi-enclosed structure. The core is made of stacked silicon steel sheets, and the core is semi-cast. A cast-in-place secondary junction box is located at the bottom of the main body. The A-end of the main body is a single high-voltage insulated support structure, and the N-end of the primary winding is located inside the secondary junction box. Because the A-end of the primary winding is a single high-voltage insulated support structure, its electrical performance is enhanced. The structure is simple, and the production mold is also simple and complex, allowing for effective quality control. Furthermore, the epoxy resin consumption is low, the volume is small, and costs are reduced.

Description

Indoor semi-enclosed single-phase voltage transformer

technical field

The utility model relates to a transformer, in particular to a voltage transformer.

Background technique:

The indoor semi-enclosed single-phase voltage transformer is a semi-enclosed product casted by epoxy resin. The iron core is made of silicon steel sheets stacked. The secondary terminals S1 and S2 are located in the secondary junction box. The incoming and outgoing lines at both ends of the primary winding are two high-voltage insulating pillar structures, which are A and N terminals respectively. The A terminal and the N terminal form an angle with each other. The disadvantages of this structure are: the A terminal and the N terminal adopt a high-voltage insulating pillar structure at an angle to each other, the structure is more complicated, the production mold is complicated, the quality control is difficult, and there are many epoxy resin consumables and large volume.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide an indoor semi-enclosed single-phase voltage transformer with convenient manufacture, compact structure, small volume and low cost, which is convenient for wiring.

The technical solutions adopted to solve the technical problems are:

The indoor semi-enclosed single-phase voltage transformer is a semi-enclosed structure casted by epoxy resin. The iron core is made of silicon steel sheets stacked. The characteristic is that the A end of the primary winding is a single high-voltage insulating pillar structure, and the N end of the primary winding is led to the secondary junction box.

The beneficial effects of the utility model are: since the A end of the primary winding is a single high-voltage insulating pillar structure, its electrical performance is enhanced, the structure is simple, the production mold is simple and complicated, and the quality control can be effectively carried out, and the epoxy resin consumables are small and bulky Small and cost-effective.

Detailed ways:

As shown in Figure 1, the indoor semi-enclosed single-phase voltage transformer of the embodiment of the utility model is a semi-enclosed product casted by epoxy resin, and the iron core 4 is made of silicon steel sheets. The lower part of 3 is provided with a cast-in-one secondary junction box 5, the secondary terminal and the N terminal 6 of the primary winding are located in the secondary junction box 5, the A terminal 2 of the primary winding is a single high-voltage insulating pillar structure, and the main body 3 is a ring Oxygen resin casting structure, the bottom surface of the main body 3 is provided with a bottom plate 1 . Since the A-end 2 of the primary winding is a single high-voltage insulating pillar structure, the original A-end and N-end adopt a high-voltage insulating pillar structure at an angle to each other. Quality control is carried out accurately, and the epoxy resin consumables are small, small in size and low in cost.
