Embodiment Construction

[0018] The present invention will be further described below in conjunction with the drawings and embodiments.

[0019] figure 1 As shown in the first embodiment, a 3-35kV electromagnetic voltage transformer includes an iron core 1, a primary winding 2, a main secondary winding 3, and an auxiliary secondary winding 4. The primary winding 2, the main secondary winding 3 and the auxiliary secondary winding 4 are all wound on the iron core 1. The iron core 1 is a rectangular iron core. The number of turns of the main secondary winding 3 and the auxiliary secondary winding 4 are the same. The auxiliary secondary winding 4 has a tap 5, and the tap 5 of the auxiliary secondary winding and the end of the auxiliary secondary winding are not connected at the same time.

[0020] Take a 10 (10 / √3) kV electromagnetic multifunctional voltage transformer as an example, which has a primary secondary winding (0.1 (0.1 / √3) kV) and an auxiliary secondary winding (0.1 / √3 ( 0.1 / 3)-0.1 (0.1 / √3) kV...

Abstract

The invention relates to a 3-35kV electromagnetic multi-functional voltage transformator which comprises an iron core, a primary winding and a main secondary winding; the primary winding and the main secondary winding are wound on the iron core; an auxiliary secondary winding is also wound on the iron core; and a tap is arranged on the auxiliary secondary winding. According to the voltage transformator, the auxiliary secondary winding with the tap is additionally arranged on the iron core, so that the functions of a grounded transformator and a non-grounded transformator are realized on the same transformator, and the 3-35kV electromagnetic multi-functional voltage transformator has a simple and compact structure, low losses and no local discharge, is convenient to use, has high safety performance, is maintenance-free, and is applicable to 3-35kV voltage systems.

Description

Technical field [0001] The invention relates to the field of electromagnetic technology, in particular to an electromagnetic voltage transformer, in particular to a multifunctional electromagnetic voltage transformer, corresponding to the 3-35kV electromagnetic voltage transformer in the power system. technical background [0002] The existing 3-35kV electromagnetic voltage transformers (hereinafter referred to as voltage transformers) can be divided into grounded voltage transformers and ungrounded voltage transformers according to the wiring method. When ordering or using, the general user is not very clear about which type of voltage transformer to use. It is even discovered during installation that the grounded voltage transformer and the ungrounded voltage transformer are confused with each other, causing inconvenience to customers and delaying the engineering cycle. Increase cost input and cause waste of resources. [0003] Most of the existing grounding voltage transformers...
