High-insulation transformer matched with power switch cabinet device

Abstract

The invention relates to the technical field of transformers, and discloses a high-insulation transformer matched with a power switch cabinet device. The high-insulation transformer comprises a box body, an isolation mechanism and an insulation mechanism, wherein a high-voltage binding post is arranged at the top of the box body; a low-voltage binding post positioned at the front end of the high-voltage binding post is arranged at the top of the box body; the top of the box body is fixedly connected with the isolation mechanism surrounding the high-voltage binding post and the low-voltage binding post; the isolation mechanism comprises an isolation cover, a protection plate, a rubber ring, a clamping groove, a clamping column, a movable plate, a movable groove, a clamping spring, a connecting rod and a pull ring; the protection plate is arranged outside the high-voltage binding post and the low-voltage binding post; the clamping groove is formed in the outer side of the protection plate; the clamping column is clamped with the clamping groove; one side of the movable plate is fixedly connected with the clamping column; the movable plate is slidably connected with the movable groove; and the other side of the movable plate is fixedly connected with the clamping spring. The high-insulation transformer overcomes the problem that an existing transformer is not good enough in insulating property when used outdoors.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a high-insulation transformer for a power switch cabinet device. Background technique [0002] A transformer is a static electrical device used to convert AC voltage and current to transmit AC power. It is based on the principle of electromagnetic induction to achieve electrical energy transfer. Transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformers in terms of their uses: power transformers are necessary equipment for power transmission and distribution, and power user distribution; test transformers can withstand voltage (boost) for electrical equipment Test equipment; instrument transformers are used for electrical measurement and relay protection of power distribution systems (PT, CT); special-purpose transformers include electric furnace transformers for smelting, welding transformers, rectifier ...

AI Technical Summary

Problems solved by technology

[0003] In recent years, with the rapid development of power equipment, the use of transformers has become more and more extensive. However, in some special places, such as outdoor environments with high temperature and humidity, the safety performance of traditional transformers is difficult to ensure their safe and long-term effective work. Therefore, in view of the characteristics of the outdoor environment, it is particularly important to design and develop a power switchgear device with high insulation performance and a high insulation transformer.
