Intelligent power transformer

Abstract

The invention discloses an intelligent power transformer, which comprises a compression ring, a core tube, a voltage transformer body and one set of press claw components, wherein three radial guide holes are formed in the core tube; the set of press claw components comprise three press claws; each press claw is provided with a press plate part, a guide slide block part and a drive plate part; the press plate parts are located in a tube cavity of the core tube; three press plate parts are clamped to form a wire clamping hole; the outer end of the guide slide block part of each press claw extends out of the tube wall of the core tube; the drive plate parts are located at the outer side of the tube wall of the core tube; each press claw slides along one corresponding radial guide hole in a reciprocating manner; the compression ring is rotationally arranged on the outer circumference wall of the core tube; the compression ring and three guide slide block parts in the press claw components are arranged adjacently; three spiral grooves are formed in one side end, adjacent to the guide slide block part of each press claw, of the compression ring; the drive plate part of each press claw is located in one corresponding spiral groove; the voltage transformer body comprises an annular base body; the wire clamping hole is located in a hole cavity of the annular base body; and the compression ring pushes the corresponding press claws to slide towards the center of the core tube when rotating. The intelligent power transformer has relatively good performance.

Description

technical field [0001] The invention belongs to the technical field of high-voltage electric power, and in particular relates to an intelligent power transformer. Background technique [0002] The power transformer is a transformer suitable for converting large voltage into small voltage or converting large current into small current in 1kv to 220kv power system for easy measurement, protection and use. [0003] Most of the existing power transformers are electromagnetic induction transformers, the working principle is the same as that of the transformer, and the basic structure is also the iron core and the primary and secondary windings. The main functions of power transformers are as follows: convert high voltage into low voltage, convert large current into small current, and then use it for measurement, control and protection. This can not only increase the range of measuring instruments, facilitate the standardization of instruments, reduce the voltage and current of c...

Problems solved by technology

[0004] Most of the existing power transformers are installed by means of flange installation or bonding, and the installation position generally needs to be reserved, so the application and promotion of power transformers are more restricted
