Abstract

A medium-high frequency transformer for a high and low tension coil comprises a high tension coil and a low tension coil which are cast integrally, an iron core is respectably mounted in a high tension coil and low tension coil and a monophase transformer formed through an upper clamping piece and a lower clamping piece for fixing the high tension coil and the low tension coil; a cushion block ismounted between the coils and the upper clamping piece, a lower cushion block is mounted between the coils and the lower clamping piece, and a baseplate and a support plate are connected at the bottompart o f the lower clamping piece; the transformer for a medium-high frequency high and low tension coil is characterized in that the high tension coil and the low tension coil adopt a plurality of conducting wires wound and connected in parallel, and form a vertical staggered and overlapped wound space. The medium-high frequency high and low tension coil transformer adopts the technical scheme that the temperature rise of the high and low tension coils are reduced to a state under which no water cooling is required, therefore the traditional medium-high frequency transformer is greatly improved, and the use by users are ensured to have great convenience and water resource economization.

Description

The medium-high frequency transformer of high-voltage coil and low-voltage coil
Technical field
The utility model relates to the high-voltage coil and low-voltage coil of low-voltage, big electric current dry type medium-high frequency transformer, belongs to field of electrical equipment.
Background technology
The traditional medium-high frequency transformer that is used for large scale industry fields such as power plant, building material industry, chemical industry, its low-voltage coil needs the continual water temperature that passes to be lower than 25 degrees centigrade water so that will be taken away by a large amount of thermal lossess that transformer coil produces by the copper pipe coiled of water flowing during operation.The shortcoming that the product of this conventional art in use exists is the way cooling that coil adopts water flowing, causing present medium-high frequency transformer is a kind of resistance loss height, inefficient product (efficient of the product that has has only 40%), and, cause user's the cost of electric energy to have more more than a times of its actual use in use owing to want the water flowing cooling.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, many lower added loss leads of a kind of employing are provided and are unified into conductor, alternating expression stagger-wound coil structure, improve the transformer energy conversion efficiency, reach and reduce loss, need not water-cooled, the medium-high frequency transformer of high-voltage coil and low-voltage coil of economize on electricity.
The technical scheme of the utility model medium-high frequency transformer of high-voltage coil and low-voltage coil is: the high-tension coil and the low-voltage coil that comprise the one cast, be installed in the iron core in the high and low pressure coil, and the fixing single-phase transformer that upper and lower folder is formed of high and low pressure coil, be equipped with cushion block between coil and the upper clamping piece, be equipped with lower cushion block between coil and the lower clamping piece, the lower clamping piece bottom connects base and supporting plate, it is characterized in that described high and low pressure coil adopts multiple conducting wires to be in parallel around the home, high-tension coil and low-voltage coil space around the home are the lap wound structure of interlocking up and down.
Medium-high frequency transformer of high-voltage coil and low-voltage coil of the present utility model, adopt multiple conducting wires parallel connection, staggered stagger-wound coil structure up and down, can reduce the kelvin effect that its high frequency operation causes significantly, thereby need not adopt the way heat radiation of water flowing, fundamentally solve the fail safe and the ease of use issues of product operation.Described high-voltage coil and low-voltage coil structure is by the research to supplementary load loss, adopt many balances group (organizing high-voltage coil and low-voltage coil), staggered lap wound conductor structure up and down more, it is a kind ofly coil to be divided into several sections vertically, a kind of aligning method of high pressure line segment and low pressure line segment interlaced arrangement that alternating expression is arranged.High-voltage coil and low-voltage coil on each stem is divided into several leakage field groups, and every group of interior high-tension coil should have the magnetic potential that equates with low-voltage coil, and its width of cloth is also equal substantially to size, differs and is no more than 5%.The technical program is reduced to a state that not water flowing is also passable with the temperature rise of high-voltage coil and low-voltage coil, thereby makes traditional medium-high frequency transformer be able to great reform, gives the saving of user's use with great facility and water resources.
