Abstract

This utility model relates to a circle amperite, which comprises an iron core and a loop. Said iron core is coiled into a circle conformation with strip and square silicon steel pieces, and the circular iron core is equipped with an opening, which is wide inward and narrow outward being an iron core air gap, which is filled with epoxide resin. The most interior layer of the amperite is the circular iron core, whose corner angles are stuck with mylan which makes arc corner angles. An insulate layer coiled by polyester film is provided outside of the mylan, and a loop layer is coiled outside of the insulate layer. A layer of mylan is stuck to the surface of the loop, and a polyester film is provided on the most outward layer. The whole amperite is of circle shape with a circular hole in the middle. This utility model makes up the disadvantages of short service life, high cost and environmental pollution of the electronic amperite, meanwhile, comparing with the EI electronic sensing amperite, this utility model is provided with low power consumption and temperature rising, long service life, simple arts, low manufacturing cost and excellent energy saving effect.

Description

The Circular Type Ballast

Technical field

The utility model relates to a kind of accessory of lighting apparatus, specifically annular Inductive ballast.

Background technology

A large amount of at present ballasts that use have two kinds, and a kind of is traditional EI type Inductive ballast, and another kind is an electric ballast.The advantage of Inductive ballast is no electromagnetic interference.And shortcoming is: volume is big, Heavy Weight; Oneself power consumption is big, temperature rise, and useful life is shorter; Complex process, the manufacturing cost height.The electric ballast energy-saving effect is better.But its shortcoming is: the manufacturing cost height, and useful life is also shorter than Inductive ballast; Its operating frequency height produces radiation and pollutes to environment, even directly influences the reception of radio and television and wireless signal; The power of product is little, all below 400W, and the most often following product of 150W.

Summary of the invention

The purpose of the utility model is to remedy above-mentioned defective, provides a kind of volume little, in light weight to society, and coil-winding length is short, and iron copper loss consumption is low, oneself power consumption is few, and temperature rise is low, long service life, easy to make, with low cost, do not produce the energy saving and environment friendly Circular Type Ballast of radiation.

The technical solution of the utility model is achieved in that it comprises iron core, coil, it is characterized in that, described iron core is by the rectangular rectangular silicon steel sheet structure ringwise of reeling, and annular core is established embrasure portion, is iron core air gap that epoxy resin in the embedding of air gap place.The innermost layer of ballast is an annular core, and the corner angle portion of iron core is stained with the wheat that makes corner angle have radian and draws adhesive tape.The insulating barrier that wheat draws adhesive tape to be entwined for mylar outward.Insulating barrier is twining coil layer outward.The sticking one deck wheat of coil surface is drawn adhesive tape.Outermost one deck is a polyester film layer.Whole ballast shape ringwise, the centre is a circular hole.

The lead-in wire of described coil is drawn out to outermost layer from coil layer, and is with the PVC sleeve pipe, is provided with the PVC collets around the bottom of sleeve pipe, and is wound with wheat and draws adhesive tape.

Because iron core of the present utility model is wound into annular by silicon steel sheet, the magnetic induction of iron core is risen, magnetic hysteresis loss descends, the corresponding minimizing of coil turn simultaneously, so iron copper loss consumption all obviously reduces, volume is little, and is in light weight.Again because, himself power consumption is little, so temperature rise is low, also prolong useful life thereupon, and kept Inductive ballast not have the advantage of electromagnetic interference.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

Present embodiment is that circular diameter was 70mm in the rectangular rectangular high-quality silicon steel sheet of 55mm was wound into wide, and outside diameter is the annular core 1 of 158mm, and annular core is 10.9mm in cutting one, is outward the opening of 5.4mm, and peristome is an iron core air gap 10.The peristome encapsulated epoxy resin of annular core (Fig. 1, Fig. 2).The innermost layer of ballast is an annular core 1.The corner angle portion of annular core 1 is stained with the wheat that makes corner angle have radian and draws adhesive tape 2 (Fig. 4).The insulating barrier 3 that wheat draws adhesive tape to be entwined for mylar outward.Twine the coil layer 4 that 250 circles form by IPEW Ф 1.6 bifilar doublings outside the insulating barrier 3, the sticking one deck wheat of coil surface is drawn adhesive tape 7, and outermost one deck is a polyester film layer 8.The lead-in wire 9 of coil is drawn out to outermost layer from coil layer, and is with PVC sleeve pipe 5, is provided with PVC collets 6 around the bottom of sleeve pipe, and is wound with wheat and draws adhesive tape.Whole ballast shape ringwise, the centre is a circular hole 11.The external diameter of present embodiment finished product is 175mm, highly is 80mm, power 1200w, ceiling voltage 230v, minimum voltage 95v ± 10v, starting current 13.8A, operating current 12.8A, 110 ℃ of work temperature rises.

The utility model has reduced own loss, has reduced the work temperature rise, thereby has reached energy-conservation effect.Do not have obvious noise during work, can not produce radiation, working life reaches 60,000 hours, and manufacturing process is simple, adapts to produce in enormous quantities, meets country and promotes the green illumination policy.Because the utility model ringwise, there is circular hole the centre, is particularly suitable for using in lamp holder place and the lamppost.
