Abstract

The invention provides a multi-step and multi-layer shielded voltage transformer, comprising: a casing, an iron core, a coil component and an insulating component, the iron core is rectangular and is vertically arranged in the casing, the coil The assembly includes a first winding and a second winding, the insulating assembly includes a first insulating layer and a second insulating layer, the first winding is wound on the iron core, and the second winding is wound on the first Outside a winding, the first insulating layer is fixedly arranged between the first winding and the second winding, and the second insulating layer is fixedly arranged outside the second winding. The purpose of the present invention is to provide a new type of voltage transformer, so as to solve the problem that the epoxy resin insulation in the prior art cannot meet the insulation requirements under high voltage.

Description

technical field [0001] The invention relates to the technical field of voltage transformers, in particular to a voltage transformer with multi-step and multi-layer shielding. Background technique [0002] Similar to a transformer, a voltage transformer is an instrument used to transform voltage, but compared with a transformer, a voltage transformer is mainly used for instrumentation and electrical protection. At present, most voltage transformers and current transformers below 35KV use ring Oxygen resin insulation structure, and the insulation strength of epoxy resin has a limit, and the insulation level of 35KV has reached the insulation limit of epoxy resin, so most of the voltage transformers of 66KV and above use oil and gas insulation, but the oil and gas insulation cost is high and maintenance is more difficult. At the same time, oil and gas insulation is not conducive to environmental protection. Therefore, a new type of voltage transformer needs to be designed to so...
