Abstract
The utility model discloses a kind of Cubicle Gas-Insulated Switchgear all-fiber current transformator, the drain pan including insulator and being respectively arranged at described insulator two ends and cover plate, insulator is socketed with some sensing rings；The internal diameter sealing ring more than described sensing ring external diameter also it is connected with between described drain pan and cover plate；Basis is the most novel not only avoid the impact on sensing ring of the gas analyte, it also avoid the impact on current transformer precision of the housing eddy current.
Description
Technical field
This utility model relates to a kind of current transformer, particularly relates to a kind of full light of Cubicle Gas-Insulated Switchgear
Fiber current mutual inductor.
Background technology
Compared with conventional electromagnetic current transformer, all-fiber current transformator has certainty of measurement height, insulate simple, nothing
The advantages such as resonance and magnetic saturation problem, dangerous without second open circuit, dynamic range is big, using all-fiber current transformator is following intelligence
One inexorable trend of Neng Hua transformer station.But, owing to installation inconvenience and housing eddy current can affect the problem of transformer precision, lead
Cause current all-fiber current transformator cannot with GIS gas cells with the use of.
Summary of the invention
This utility model provides a kind of Cubicle Gas-Insulated Switchgear all-fiber current transformator, can be very
Installation, transformer precision is coordinated also to be guaranteed with GIS gas cells easily.
For reaching above-mentioned purpose, the technical scheme of this novel employing is: a kind of Cubicle Gas-Insulated Switchgear is complete
Optical fiber current mutual inductor, the drain pan including insulator and being respectively arranged at described insulator two ends and cover plate, insulator overlaps
It is connected to some sensing rings；The internal diameter sealing ring more than described sensing ring external diameter also it is connected with between described drain pan and cover plate, sensitive
Ring is placed in the molecular cavity of sealing ring, drain pan, cover plate and insulation.
As optimization, the side that described drain pan is relative with cover plate is provided with the positioning step adaptive with described insulator,
Conveniently install, and insulator will not occur radial deflection.
As optimization, between described insulator and drain pan, between insulator and cover plate, it is provided with sealing ring, it is ensured that good
Sealing.
As optimization, the lateral surface of described drain pan and cover plate is provided with some screwed holes, the aperture of screwed hole and position chi
Very little consistent with other assembly units of GIS, the convenient connection with other assembly units.
As preferably, described drain pan, sealing ring and cover plate are bolted to connection, easy disassembly.
The beneficial effects of the utility model are: this transformer is installed on outside GIS gas cells, can avoid gas analyte
Impact on sensing ring；Circulation is blocked, it is to avoid the housing eddy current impact on current transformer precision by insulator.
Accompanying drawing explanation
Fig. 1 is this new structure schematic diagram；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is A-A sectional view in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings the scheme of the application is described in detail.
A kind of Cubicle Gas-Insulated Switchgear all-fiber current transformator as shown in Figure 1, including insulator 5 and
Being respectively arranged at drain pan 1 and the cover plate 4 at insulator 5 two ends, the side that drain pan 1 is relative with cover plate 4 is provided with fits with insulator 5
The two ends of insulator 5 during installation, are respectively placed in positioning step, not only install quick and convenient by the positioning step joined, and
Insulator can be limited offset.Between insulator 5 and drain pan 1, between insulator and cover plate 4, it is provided with sealing ring 7, with
The sealing effectiveness ensured.
Insulator 5 is socketed with some sensing rings 2, is also connected with internal diameter between drain pan 1 and cover plate 4 more than sensing ring 2
The sealing ring 3 of external diameter, drain pan 1, sealing ring 3 and cover plate 4 connect by bolt 6 is fixing.
Being connected with other parts of GIS gas cells for convenience of this transformer, the lateral surface at drain pan 1 and cover plate 4 is arranged
Have some screwed holes 8, the aperture size of screwed hole 8 and position dimension all with other part sizes for connection one of GIS gas cells
Cause.For convenience of processing, screwed hole 8 can extend through drain pan 1 and cover plate 4, after installation, bolt is sealed by screwed hole.
During use, this new transformer is independently installed outside GIS gas cells by screwed hole, pass through communication cable
It is connected with electric unit.Owing to sensing ring is positioned at the sealing cavity that drain pan, cover plate, sealing ring and insulator are formed, it is to avoid
The impact on sensing ring of the gas analyte；And carry out blocking at circulation and sealing by insulator and sealing ring between gas cells
Reason, it is to avoid the housing eddy current impact on current transformer precision.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, without departing from the some improvement under this utility model principle premise and
Retouching, also should be regarded as protection domain of the present utility model.
