Abstract

The utility model discloses a hollow conductor enamelled round copper wire which comprises a copper round wire conductor and an insulating layer, wherein the insulating layer is uniformly coated over the copper round wire conductor, and the copper round wire conductor is a hollow conductor. The hollow conductor enamelled round copper wire provided by the utility model is reasonably designed, has a simple structure and enables temperature rise and loss in the process of energy conversion of a motor or a transformer winding to be reduced and better efficiency and performance to be obtained.

Description

The hollow conductor enamelling cuprum round line

Technical field

The utility model relates to a kind of hollow conductor enamelling cuprum round line.

Background technology

Enamelled wire is the material of making the motor winding, motor is mechanical energy by the effect of enamelled wire winding with electric energy conversion, enamelled wire is comprised of conductor and insulating barrier two parts, conductor material is the high conductive materials such as copper, aluminium, insulating barrier is generally insulating varnish, motor is in running, the enamelled wire winding can produce a large amount of heat by electric current the time, raising along with heat, insulating barrier can occur and puncture, short circuit in winding makes burn-down of electric motor, conductor also can the generation current loss under hot environment, affects conversion of energy efficient and motor performance.

Present Production of Enamel Wires technology generally adopts the resistance to elevated temperatures that improves insulating varnish to guarantee the reliability of insulating barrier, but owing to being subject to the restriction of material ability, the insulation property of enamelled wire can't effectively be ensured.

Summary of the invention

Can not ensure enameled wire performance in order to overcome existing insulating varnish material, motor or transformer in running, the problem that heat rising insulating barrier may be breakdown, short circuit in winding, electrical equipment burn etc., the utility model provides a kind of hollow conductor enamelling cuprum round line.

The technical solution adopted in the utility model is:

The hollow conductor enamelling cuprum round line comprises copper round wire conductor and insulating barrier, and it is outer that described insulating barrier evenly is coated in described copper round wire conductor, and it is characterized in that: described copper round wire conductor is hollow conductor.

Hollow conductor described in the utility model is formed by die drawn.Adopt the design of conductor boring, in conductor, pass into water or other coolants carry out hydronic method, enamelled wire is cooled off, make winding in service being in all the time under the low-temperature condition of energising, guarantee that insulating layer of conductor can not produce high temperature and puncture, reduce temperature rise and loss in the transport process, obtain better efficient and performance.

The utility model is for the wire winding that has electric current to flow through, and is meaningful especially such as power transformer, high-voltage motor etc.

The beneficial effects of the utility model are embodied in:

(1) winding of the utility model hollow conductor enamelling cuprum round line manufacturing is installed on the stator of motor or Transformer Winding, lead-in wire can be connected cooling system, when electric operation, system is cooled off winding by external refrigeration, guarantee that winding temperature rise is controlled, make winding in service being in all the time under the low-temperature condition of energising, guarantee that insulating layer of conductor high temperature can not occur and puncture.Improve the reliability of electric operation;

(2) the utility model hollow conductor enamelling cuprum round line has the large characteristics of surface area, can alternating current producing kelvin effect during by conductor;

(3) reasonable in design, simple in structure, reduce temperature rise and loss in the motor winding conversion process of energy, obtain better efficient and performance.
