Description
Technical field
This utility model belongs to SF6 Cubicle Gas-Insulated Switchgear all-fiber current transformator technical field,
Especially relate to a kind of all-fiber current transformator structure.
Background technology
Because all-fiber current transformator has that certainty of measurement is high, insulation is simple, resonance free and magnetic saturation problem, opens without secondary
The advantages such as road is dangerous, dynamic range is big, it applies increasingly extensive in following Intelligent transformer station.But it coordinates installation with GIS,
Transformer assembling need to be redesigned, and take the structure blocking circulation to ensure transformer precision.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of all-fiber current transformator structure.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
A kind of all-fiber current transformator structure, including at the bottom of the ring-type shell of transformer, is equipped with in the right side edge at the bottom of ring-type shell
Annular sidewall, is equipped with ring-type cap at the right openings of annular sidewall, and multiple bolts that install of circle distribution cross ring-type shell
The end, annular sidewall and ring-type cap, connect and compose ring-type stereochemical structure by three, and tight by installing the nut at bolt two ends
Gu, all it is being shaped with, at the bottom of ring-type shell and inside ring-type cap, the annular recess that position is corresponding, is being built-in with O-ring seal at annular recess,
Installing ring-type insulator between two O-ring seals, ring-type stereochemical structure is sealed by ring-type insulator by internal ring, constitutes and seals
Annulus, in the annulus sealed, sensing ring is installed, the communication cable of sensing ring is by the hole at the bottom of ring-type shell
Pierce and be connected with outside electric unit at the bottom of ring-type shell.
And, it is mounted on cyclic sealing gasket at annular sidewall with at the bottom of ring-type shell and on the two sides that contact of ring-type cap,
The wire hole of communication cable at the bottom of ring-type shell is provided with sealing cableties.
And, the plurality of bolt that installs is to install bolt more than eight of even circumferential distribution.
Advantage of the present utility model and good effect be:
This utility model all-fiber current transformator sensing ring independently installed in the outside transformer drain pan of GIS gas cells and
Between end cap, and carry out blocking circulation and encapsulation process by insulator and sealing ring between gas cells, prevent housing eddy current
Affecting current transformer precision, sensing ring is connected with external electrical unit by communication cable, simple in construction, good looking appearance.
