Multipurpose combined protection transformer

Abstract

The invention provides a multipurpose combined protection transformer, and relates to the technical field of transformers. The multipurpose combined protection transformer comprises a transformer body, wherein the transformer body comprises a fixed base; protection side plates are vertically mounted at the positions of four edges of the upper end of the fixed base; a top plate is horizontally arranged at the upper ends of the protection side plates; a high-pressure sleeve and a low-pressure sleeve are mounted above the top plate; a lightning arrester is mounted on one side of the high-pressuresleeve; a fuse is arranged between the lightning arrester and the high-voltage sleeve; and two mounting frames are arranged at the lower end of the fixed base. In the multipurpose combined protectiontransformer, before the lightning arrester is installed in the high-voltage sleeve, damage caused by lightning can be effectively reduced, and safe operation of the transformer is maintained; the fuse is installed between the lightning arrester and the high-voltage sleeve, the fuse protects the transformer from damage caused by overcurrent, and the safety of the transformer is protected; and in addition, the whole device is stable in performance, and safe and reliable in action, no misoperation is generated, the whole device is convenient to install and disassemble, and the transformer is convenient to maintain.

Description

technical field

[0001] The invention relates to the technical field of transformers, in particular to a multi-purpose combined protection transformer. Background technique

[0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the use, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , reactors, transformers, etc.). Circuit symbols often use T as the begi...
