Abstract

A machining technology for a base of a large transformer, for use in machining of a base of a large transformer, comprising the following steps: A, machining a base flange; B, welding feet; C, mounting multi-way bodies; D, performing heat treatment on a workpiece; and E, coating the whole surface of the workpiece with a protection layer. The machining technology implements simple manufacturing and high precision.

Description

technical field [0001] The invention designs a processing technology of a base for a large-scale transformer, which is used for processing the base of a large-scale transformer. Background technique [0002] Transformers are divided into two categories: voltage transformers and current transformers, which are devices that convert voltage or current in proportion. Its function is mainly to convert high voltage or high current into standard low voltage (100V) or standard small current (5A or 1A, both refer to rated value) in proportion, so as to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. change. At the same time, the transformer can also be used to isolate the high-voltage system to ensure the safety of people and equipment. A device that converts voltage or current proportionally. [0003] Large-scale transformers need to be installed on the base during use, and the existing bases are gene...
