Nylon insulated voltage transformer

Abstract

The invention discloses a nylon insulated voltage transformer comprising a bottom plate for fixing the transformer, an annular iron core is arranged on the bottom plate, a voltage transformer coil wound on the annular iron core and a primary electrical connection end electrically connected with the voltage transformer coil. The voltage transformer coil is sleeved by a thermal insulation layer in asealing way. A nylon inclusion formed by injection molding nylon is used outside the transformer to wrap the annular iron core, the voltage transformer coil and the transformer line to realize insulation, and the primary electrical connection end is exposed on the surface of the nylon inclusion. The nylon inclusion has good insulation performance and is convenient to process and is not liable todeform under heating and stress and can effectively replace epoxy resin to realize insulation and isolation of the internal components of the voltage transformer and solve the harmfulness and pollution problems caused by the epoxy resin. Besides, the voltage transformer coil is sleeved by the thermal insulation layer in a sealing way to effectively block the high temperature during melt molding ofthe nylon inclusions and avoid the influence on the product performance caused by the coil damage due to the temperature greater than that of the transformer coil bearing wiring during nylon injection molding.

Description

technical field [0001] The invention relates to a voltage transformer. Background technique [0002] In the prior art, the voltage transformer is generally insulated by epoxy resin material, but because epoxy resin is carcinogenic and difficult to degrade, when the voltage transformer is scrapped and discarded, it will seriously pollute the environment and endanger human health. Therefore, it is necessary to find a method that can replace the epoxy resin material to realize the insulation of the voltage transformer. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a voltage transformer insulated by nylon material instead of epoxy resin material. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A nylon insulated voltage transformer, comprising a bottom plate for fixing the transformer, a ring-shaped iron core arranged on the bottom plate, a...
