Description
Technical field
The present invention relates to current transformer technical field, the optical fiber that has in particularly a kind of all-fiber current transformator is protected
Shield harvester, adopt the all-fiber current transformator of this harvester and the installation side of this all-fiber current transformator
Method.
Background technology
Current sensor/transformer is the visual plant of relay protection and electric energy metrical in power system, for measuring biography
Size of current in defeated, and the size of current measuring is sent to measuring instrument and protective relaying device.Current transformer
The safe and stable operation of long-time stability, reliability and safety and power system is closely related.Traditional electromagnetic type electric current is mutual
, due to there is unvanquishable difficulty in some principles, for example, ferromagnetic resonance, magnetic saturation, band limiting etc., in high voltage for sensor
Grade is run has potential safety hazard, and the all-fiber current transformator based on Faraday effect can overcome problem above, therefore
Power system is applied quite varied.
When installing and using, the optical fiber of the primary side sensing unit of all-fiber current transformator (abbreviation transformer) must access
Mutual inductor case, the fused fiber splice of the harvester output after the rack wire casing and in transformer, but, optical fiber welding after welding
The protection problem that the protection problem of contact, the process problem of slack and transformer are worn during optical fiber delivery often becomes
Transformer optical fiber cabling is succinct, attractive in appearance and a difficult problem for less trouble for impact.At the optical fiber of traditional all-fiber current transformator
As illustrated in figs. ia and ib, setting harvester in all-fiber current transformator cabinet 11, in full optical-fiber current mutual inductance for reason form
(as shown in Figure 1a) or following (as shown in Figure 1 b) configuration fiber optic protection box 12 above device cabinet 11, fiber management tray 3 is sealed in light
In fine protecting box 12, optical fiber 7 (i.e. the optical fiber 7 of the harvester output) disk in fiber optic protection box 12 for the disk that transformer is worn is fine
In box 3, disk passes through optical fiber hole 13 and the primary side sensing unit of setting on fiber optic protection box 12 in the optical fiber 7 in fiber management tray 3
Optical fiber phase welding, when carrying out three-phase current measurement, three sets of harvesters of setting, optical fiber in all-fiber current transformator cabinet 11
Also accommodate three fiber management trays 3 in protecting box 12, the optical fiber 7 of three sets of harvester outputs respectively disk in fiber optic protection box 12 three
In individual fiber management tray 3.This optical fiber processing form haves such problems as profile unsightly and installation footprint is larger.Fig. 2 is to pass
Another kind of structural representation of the all-fiber current transformator optical fiber processing form of system, in all-fiber current transformator cabinet 11
It is individually for optical fiber 7 and a module (i.e. optical fiber disposal unit 15) is set, fiber management tray 3 is arranged in optical fiber disposal unit 15, mutual inductance
, in the fiber management tray 3 in optical fiber disposal unit 15, disk is fine in disk for disk for the optical fiber 7 (i.e. the optical fiber 7 of harvester output) of device configuration
Optical fiber 7 in box 3 is entered live rack wire casing 14 by the wire hole of optical fiber disposal unit 15 and is melted with the optical fiber phase of sensing unit
Connect.In welding, the optical fiber 7 in the fiber management tray 3 of setting in optical fiber disposal unit 15 is taken out and carries out welding, after welding finishes
By fusion point and slack again disk in fiber management tray 3, then it is mounted in optical fiber processing unit 15, and integral installation is mutual
The vacant module position of sensor.Consider to be easily installed, be fixed easily, the composite factor such as operation maintenance is convenient and avoids interference, lead to
Often that this optical fiber treating device is arranged on all-fiber current transformator cabinet 11 wall, the optical fiber hole of optical fiber disposal unit 15 with
And fiber management tray 3 enter fine hole and optical fiber hole is arranged on all-fiber current transformator cabinet 11 wall that communicated with the external world, such as Fig. 2
Shown, therefore concrete optical fiber cabling is：The optical fiber that harvester is exported is introduced to optical fiber processing unit 15, then from optical fiber processing list
Unit 15 optical fiber holes are drawn outside all-fiber current transformator cabinets 11, then from being arranged on all-fiber current transformator cabinet 11 wall
Fiber management tray 3 enter that fine hole (simultaneously communicating with the fine hole that enters of optical fiber disposal unit 15) enters fiber management tray 3 and disk is in fiber management tray 3,
(simultaneously another with optical fiber disposal unit 15 from the optical fiber hole of the fiber management tray 3 being arranged on all-fiber current transformator cabinet 11 wall again
Outer optical fiber hole communicates) lead to outside all-fiber current transformator cabinet 11 so that optical fiber 7 enters rack wire casing 14 and sensitivity list
The optical fiber phase welding of unit, therefore optical fiber cabling is in disorder；Especially when three-phase current measures, need to arrange in optical fiber processing unit 15
Three fiber management trays 3 or the fiber management tray 3 (as shown in Figure 2) of one multiple structure of setting, optical fiber processing unit 15 and fiber management tray 3 are equal
More fine holes that come in and go out are set so that the discrepancy of each optical fiber, therefore optical fiber cabling is more aobvious in disorder.This optical fiber processing to sum up can be obtained
Form have that optical fiber cabling is in disorder, operation maintenance is inconvenient and profile unsightly the shortcomings of.

, all using electromagnetic shielding material, described device pallet is using by panel beating bending or metal plate punching or panel beating welding or cast aluminium one-tenth for cover
" L " shape structural member of the mode molding of type.
9. a kind of all-fiber current transformator, including primary side sensing unit it is characterised in that also include claim 1 to 8 it
The harvester with fiber optic protection described in one, described harvester by be flexibly connected with the slot in mutual inductor case with
Insert mutual inductor case and take out from mutual inductor case, the optical fiber of fiber management tray output is drawn from the second optic fibre hole and compacting joint
Optical fiber phase welding with primary side sensing unit afterwards, the fusion point of optical fiber being formed after welding and superfluous is put in described fiber management tray counter offer
Remaining optical fiber.
10. all-fiber current transformator according to claim 9 is it is characterised in that the described collection with fiber optic protection
Device is provided with more than three, is additionally provided with multiphase data processing circuit, in described each harvester in described mutual inductor case
The outfan of circuit board be all connected with multiphase data processing circuit.
A kind of 11. installation methods of all-fiber current transformator according to claim 9 are it is characterised in that in a pre-installation
It is the described harvester with fiber optic protection to be arranged in mutual inductor case, when mounted by described harvester from mutual inductance
Take out in device cabinet, open fiber management tray, the optical fiber that fiber management tray is exported after the second optic fibre hole and compacting joint are drawn with once
The optical fiber phase welding of side sensing unit, and after fused fiber splice finishes to welding after formed optical fiber pass through the second optic fibre hole and pressure
Joint processed carries out back disk to fiber management tray thus by the fiber reel of fusion point and redundancy in fiber management tray, turning off fiber termination box and incite somebody to action
Described harvester is inserted in mutual inductor case.
