Description
Technical field
The utility model relates to a kind of current transformers, and in particular to a kind of electronic current mutual inductor.
Background technique
With economic continuous development, society to electric power resource using more and more extensive, in order to guarantee electric system energy
Enough safety is economically run, so monitoring and measuring must be carried out to the operating condition of power equipment.But due to measuring instrument
Table and protective device cannot directly access in a high-tension apparatus, so needing to convert the high voltage of primary system and high current
At low-voltage and low current, supplies measuring instrumentss and protective device uses.It is most common to be able to carry out setting for these convert tasks
Standby is exactly the mutual inductor that we usually say, wherein what is converted to voltage is voltage transformer, is to what electric current was converted
Current transformer.
Fig. 1 show currently used electronic current mutual inductor structure, and the electronic current mutual inductor is by mutual inductor shell
Body and fiber termination box are constituted, wherein transformer housing is set in outside a main conductive circuit conducting rod, which connects
Docking shell is connect, the other end connects disk insulator, forms mutual inductor gas chamber inside transformer housing, fills SF6 in the gas chamber
Gas.Light box is arranged in transformer housing, which is equipped with an optical fiber hole worn for light.The electronic current
Mutual inductor has the shortcomings that volume is big, at low cost.
Utility model content
In view of the above-mentioned problems, a kind of the purpose of this utility model is to provide structures electronic current simple, small in size
Mutual inductor.
In order to achieve the above purposes, the technical solution adopted by the utility model is:
A kind of electronic current mutual inductor comprising disk insulator, optical fiber and electrical detection unit, the disc type insulation
Son is equipped with disk fibre slot, and the disk fibre slot is equipped with an optical fiber hole；The optical fiber is arranged on disk fibre slot, and one end is threaded through
In optical fiber hole；The electrical detection unit is integrated on optical fiber, and is arranged on disk fibre slot with optical fiber.
The disk insulator includes metal flange, epoxy resin and electric conductor, and epoxy resin is connected to electric conductor periphery,
And metal flange is connected to epoxy resin periphery；The disk fibre slot is arranged on metal flange, and structure annular in shape.
The inner face and/or outer end face of the metal flange are equipped with the disk fibre slot.
The electrical detection unit includes light source, magneto-optic memory technique and analyzer.
After adopting the above scheme, the utility model on disk insulator by opening up disk fibre slot, and will electrically detect list
Member becomes one with optical fiber to be assemblied on disk fibre slot after structure, compared with traditional electronic current mutual inductor, is completely abolished
Transformer housing and mutual inductor gas chamber substantially reduce small product size and reduce product cost, while reducing product gas leakage wind
Danger promotes product reliability.

Specific embodiment
As shown in Figures 2 to 4, the utility model discloses a kind of electronic current mutual inductor comprising disk insulator
1, optical fiber 2 and electrical detection unit (not indicated in figure).
Wherein, disk insulator 1 includes metal flange 13, epoxy resin 12 and electric conductor 11, and epoxy resin 12 is connected to
11 periphery of electric conductor, and metal flange 13 is connected to 12 periphery of epoxy resin.Pair of metal flange 13 and a main conductive circuit
Body contact body 3 connects, and electric conductor 11 and the conducting rod 4 of a main conductive circuit are electrically connected.It is equipped with extremely on metal flange 13
The disk fibre slot 131 of a few cyclic structure, the disk fibre slot 131 are equipped with an optical fiber hole 132.Above-mentioned optical fiber 2 is arranged in disk fibre slot
On 131, and one end of optical fiber 2 is threaded through in optical fiber hole 132, and is connected to backstage, to realize that data are transmitted.Wherein, disk fibre slot
131 both can be set the inner face in metal flange 13, the outer end face of metal flange 13 also can be set, naturally it is also possible to simultaneously
It is arranged in inner face and outer end face (as shown in Figure 2).The length of optical fiber and its disk in disk fibre slot set circle number can basis
The size of current in primary leading circuit is calculated.
Above-mentioned electrical detection unit is integrated on optical fiber, and is set along in disk fibre slot 131 with optical fiber 2.This is electrically examined
Survey unit is existing conventional structure comprising light source, magneto-optic memory technique and analyzer.
The working principle of the electronic current mutual inductor of above structure is as follows: when the electric current in a main conductive circuit passes through
When the electric conductor 11 of disk insulator 1, magnetic field will be generated around electric conductor 11, under the action of the magnetic field, electrical detection is single
The light source of member can generate corresponding angle offset when passing through magneto-optic memory technique, and the deviation angle of analyzer measurement at this time can real-time measurement
Out in a main conductive circuit electric current size, then by optical fiber 2 be transferred to backstage carry out real-time monitoring.
Compared with traditional electronic current mutual inductor, the utility model on disk insulator 1 by opening up disk fibre slot
131, and optical fiber 2 and electrical detection unit assembly have been completely abolished into transformer housing and mutual inductor gas on disk fibre slot 131
Room substantially reduces small product size and reduces product cost, while reducing product gas leakage risk, promotes product reliability.
The above is only the utility model embodiment, not makees any limit to the technical scope of the utility model
System, thus any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent variations with repair
Decorations, are still within the scope of the technical solutions of the present invention.
