Abstract
The utility model relates to a high current coil for low voltage transformers. The high current coil comprises a coil body, fixing boards, a front connecting board, and a rear connecting board. An assembly method of the high current coil includes the steps: first, a traditional round tube or square tube coil is modified into a hexagonal shape; second, the coil is divided into a plurality of segments according to the size and number of magnetic circuits; third, each segment is machined with a common bender; fourth, the segments are assembled into an integrated coil through the fixing boards. The processing method of the high current coil is simple and feasible, high in flexibility, suitable for small-batch products, applicable to processing of various coil conductors such as copper, aluminum and copper-aluminum alloy conductors, and suitable for high voltage high-current coils for various types of transformers.
Description
Technical field
This practicality relates to transformer coil technical field, is specially a kind of large current coil of low-tension transformer.
Background technology
Transformer is a kind of static electrical equipment.Utilize electromagnetic induction principle between two or more coils, a kind of voltage and current of grade is converted to the voltage and current of the another kind of grade of same frequency, and electric energy transmitting.Coil is the basic element of character of transformer voltage of transformation, and coil is made up of the different numbers of turn, because the one turn voltage of different coils is the same, therefore, need to make coil have the different numbers of turn, reaches different voltage.
At present, coil shape is generally flexible or square tube, processes large current coil and needs special equipment, or open mould, coil or superposeed by pie, needs high power welding equipment, utilizes special bender or large-tonnage punch press, and work clamp mould that need to be supporting, or utilize the technique such as extruding or cast, powder metallurgy, also need to open mould, its equipment complexity, ordinary enterprises does not have this kind equipment, processing charges costliness; Mould opens that the cycle is long, and expense is high, is difficult to be suitable for the product process requirements of many specifications, small lot.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of large current coil of low-tension transformer, to solve the problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: a kind of large current coil of low-tension transformer, its large current coil comprises: coil, fixed head, front connecting plate, rear connecting plate, shown in coil outer-hexagonal shape structure, coil size successively decreases step by step, shown in be connected and fixed by fixed head between coil, between fixed head, fix by hold-down nut, the coil of both sides outermost end is provided with front connecting plate, rear connecting plate, front connecting plate and rear connecting plate are provided with some connecting holes, and connecting hole is matrix form and distributes on front connecting plate and rear connecting plate.
Described large current coil processing method is: first make traditional cylinder or square tubular coil into hexagon; Secondly, coil is divided into some sections according to magnetic circuit size and number; Then, every section of coil is processed with common bending machine; Finally every section of coil is assembled into a whole coil by fixed head.
Shown in coil be copper, aluminium, albronze material.
Described coil number is 2-10.
Described fixed head is provided with 2-6 hold-down nut.
Compared with public technology, there is following advantage in the utility model: processing method simple possible of the present utility model, and flexibility ratio is high, is applicable to pilot, be applicable to the various coil-conductor processing such as copper, aluminium, albronze, be suitable for the low-voltage, high-current coil of all types of transformers.
