Abstract
The utility model discloses a kind of transformer core fastener, including：Insulation tube, insulating washer, fastening screw, metallic supports, steel drawstring, iron core；The steel drawstring, fastening screw and metallic supports are sequentially connected；The fastening screw connection fastening metal support member and steel drawstring；The insulating washer is arranged between the top of fastening screw and metallic supports；The insulation tube is arranged between the bottom of fastening screw and metallic supports；There is a segment distance between the steel drawstring and iron core；The steel drawstring is separated with transformer insulated, and steel drawstring is in electric suspended state.The utility model reduces the labor intensity of operative employee, shortens the working time, simple and convenient, improves operability, greatly improves operating efficiency and reduces accident rate, improves security reliability.
Description
Technical field
The utility model is related to a kind of transformer, more particularly to a kind of change extension iron core fastener.
Background technology
Current iron core steps up with drawstring to be glass fiber resin pickup adhesive tape or one point earth formula steel drawstring, glass fiber resin pickup
Adhesive tape complex process, size, which are difficult to control, surface is easily dirty is difficult to clear up.One point earth formula steel drawstring solves glass fiber leaching tree
The drawbacks of fat adhesive tape, but in transport and running, by shaking the possibility that is influenceed ground wire junction to have loosening,
Suspended discharge can be produced, causes product not use, it is necessary to be repaired, greatly loss is caused.
Utility model content
For problems of the prior art, the utility model proposes a kind of transformer core fastener, including：Absolutely
Edge pipe, insulating washer, fastening screw, metallic supports, steel drawstring, iron core；
The steel drawstring, fastening screw and metallic supports are sequentially connected；
The fastening screw connection fastening metal support member and steel drawstring；
The insulating washer is arranged between the top of fastening screw and metallic supports；
The insulation tube is arranged between the bottom of fastening screw and metallic supports；
There is a segment distance between the steel drawstring and iron core；
Insulated separation between the steel drawstring, iron core, metallic supports three, steel drawstring is in electric suspended state.
Wherein, the iron core is located at the lower section of the steel drawstring and fastening screw.
Wherein, the metallic supports ground connection.
Wherein, the iron core grounding.
The beneficial effects of the utility model are：The labor intensity of operative employee is reduced, the working time is shortened, simple side
Just, operability is improved, operating efficiency is greatly improved.
Brief description of the drawings
Fig. 1 is a kind of structural representation of transformer core fastener of the present utility model.
Embodiment
The utility model is elaborated below in conjunction with the accompanying drawings.
The utility model is a kind of transformer core fastener developed according to designed by needing product.It solves profit
Swathed to fasten the tedious work of lamination with glass fiber resin pickup, while solving one point earth formula steel drawstring earthing position pine
Suspended discharge problem caused by dynamic, it is adaptable to the core form of various needs fastenings, and simple and practical, highly versatile, just
Prompt economic and reliable.
The purpose of this utility model is to provide a kind of iron core fastener easy to operate, safe and reliable, transport and
In running, the suspended discharge caused by earth stud loosens can be prevented.
As shown in figure 1, a kind of transformer core fastener of the present utility model includes：Insulation tube, insulating washer, fastening
Screw rod, metallic supports, steel drawstring, iron core.
The steel drawstring, fastening screw and metallic supports are sequentially connected.
The iron core is located at the lower section of the steel drawstring and fastening screw.
The fastening screw connection fastening metal support member and steel drawstring, and metallic supports and steel drawstring are carried out tight
Gu.The insulation tube and insulating washer are put between fastening screw and metallic supports, play a part of insulation, make fastening spiral shell
Bar is with metallic supports without electrical connection.
The insulating washer is arranged between the top of fastening screw and metallic supports, for the fastening screw that insulate
Portion and metallic supports.
The insulation tube is arranged between the bottom of fastening screw and metallic supports, the bottom for the fastening screw that insulate
And metallic supports.
There is a segment distance between the steel drawstring and iron core, holding is not contacted.Protected between the metallic supports and iron core
State of insulation is held, is each grounded respectively.
Equal insulated separation between the steel drawstring, iron core, metallic supports three.
The steel drawstring is separated it with transformer core grounding SI semi-insulation by insulating washer and insulation tube, draws steel
Band is in electric suspended state.The steel drawstring is by cross-over block, packing ring by itself and transformer core grounding SI semi-insulation point
From, make steel drawstring be in electric suspended state, using the capacity effect between the metallic object of completely insulated separation, make suspension steel draw
Band induces the electrical body close to 0 current potential in the electric field, by rational insulation mode, it is not produced to surrounding metal structures
Raw electric discharge, reaches that fastening means is simple, reliable, and solves one point earth formula steel drawstring, is led during long-play vibrations
The earth point of cause loosens caused suspended discharge problem.
By insulation tube in figure and insulating washer, steel drawstring and fastening screw and metallic supports insulation are separated, reached
The purpose suspended to steel drawstring.Steel drawstring is in electric field and induces relatively low floating potential, in the insulation of steel drawstring surface wrap
Crimped paper ensures that it does not produce electric discharge.This mode does not need ground lead, it is to avoid cause because ground lead binding post loosens
Suspended discharge.Verified by actual product, such a mode operates letter, reliability high.
Although describing the utility model by embodiment, it will be appreciated by the skilled addressee that the utility model has perhaps
Shape changeable and change without departing from spirit of the present utility model, it is desirable to appended claim include these deformation and change without
Depart from spirit of the present utility model.
