Abstract
The utility model is related to electronic technology field, and in particular to a kind of current transformer.The current transformer of gas insulation switch cabinet, including an iron core, iron core surface are wound with winding coil, and iron core is a ring bodies, and the iron core for being wound with winding coil is coated with a closed shell；Space between shell and the iron core for being wound with winding coil is filled with SF6 insulating gas.This patent is used for gas insulation switch cabinet, and because iron core is ring-type, one time bus can be passed through from current transformer center, therefore reduces the space that gas insulation switch cabinet is used to place current transformer.Moreover, this patent is filled with SF6 insulating gas between shell and iron core so that less space can be left between shell and iron core, the volume of current transformer in itself is reduced, further reduce the volume of gas insulation switch cabinet.
Description
Technical field
The utility model is related to electronic technology field, and in particular to a kind of current transformer.
Background technology
Current transformer for gas insulation switch cabinet is the indispensable part of gas insulation switch cabinet, is measurement
With protection system signal source one of., it is necessary to which the bus and electric current of gas insulation switch cabinet is mutual in installation process
Sensor is in contact, and the space for placing current transformer will occupy more skies while place current transformer and bus
Between, therefore, it is larger that the volume of gas insulation switch cabinet is done.Compare and be not convenient for carrying.
Utility model content
The purpose of this utility model is to provide a kind of current transformer of gas insulation switch cabinet, solved above at least
One technical problem.
The technical problem that the utility model is solved can be realized using following technical scheme：
The current transformer of gas insulation switch cabinet, including an iron core, the iron core surface are wound with winding coil, its
It is characterised by, the iron core is a ring bodies,
The iron core for being wound with winding coil is coated with a closed shell；
Space between the shell and the iron core for being wound with winding coil is filled with SF6 insulating gas.
This patent chooses ring-type iron core as the iron core of this patent transformer in numerous iron core patterns, exhausted for gas
Edge switch cubicle.Because iron core is ring bodies, one time bus can be passed through from current transformer center, therefore reduce gas-insulated
Switch cubicle is used for the space for placing current transformer.Moreover, this patent is filled with SF6 insulating gas between shell and iron core,
So that less space can be left between shell and the iron core for being wound with winding coil, the body of current transformer in itself is reduced
Product, further reduces the volume of gas insulation switch cabinet.And gas has mobility, more preferable insulation effect can be reached.Separately
Outside, gas insulation switch cabinet is also filled with SF6 insulating gas for placing the bus-bar room of bus, and current transformer is placed into it
In, draught head is not present in both.
The shell is the fire-retardant organic material shell using fire-retardant organic material.Further improve insulation effect.
The ring bodies can be torus, square ring body or oval ring body.Conveniently it is fixed on gas insulation switch cabinet
Diverse location.
Be wound with the iron core of winding coil external diameter and internal diameter difference be 3cm~5cm, the external diameter of the shell with it is interior
The difference in footpath is 3.1cm~5.5cm.Space between shell and the iron core for being wound with winding coil is smaller, reduces Current Mutual Inductance
The volume of device in itself.
Also include a housing, a bus of the shell and gas insulation switch cabinet is both secured in the housing, institute
State and SF6 insulating gas is also filled with housing.It is both placed in the bus-bar room of gas insulation switch cabinet, further improves insulation
Property.
The winding coil is the copper conductor winding coil that copper conductor is made.The cost of copper conductor is low, good conductivity.
The copper conductor outer surface is coated with layer of metal zinc.Zinc hardly changes in dry air, plays U.S.
Sight, antirust etc. are acted on.
Or, the copper conductor outer surface is coated with one layer of insulated paint.The purpose of insulation can be reached, but it is cost-effective.
Brief description of the drawings
The part-structure profile that Fig. 1 cuts for a kind of direction along central axis of structure of the utility model；
Fig. 2 is the part-structure profile that edge of the present utility model is cut perpendicular to the direction of central axis.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face, which combines to be specifically illustrating, is expanded on further the utility model.
Reference picture 1, Fig. 2, the current transformer of gas insulation switch cabinet, including an iron core 2, the surface of iron core 2 is wound with
Winding coil, iron core 2 is a ring bodies, and the iron core 2 for being wound with winding coil is coated with a closed shell 1；Shell 1 with around
The space being formed between the iron core 2 of winding coil is filled with SF6 insulating gas.This patent is used for gas insulation switch cabinet, due to
Iron core 2 is ring-type, and one time bus can be passed through from current transformer center, therefore reduces gas insulation switch cabinet for placing
The space of current transformer.Moreover, this patent between shell 1 and iron core 2 be filled with SF6 insulating gas 3 so that shell 1 with
Less space can be left between iron core 2, the volume of current transformer in itself is reduced, further reduces gas-insulated switch
The volume of cabinet.And gas has mobility, more preferable insulation effect can be reached.In addition, gas insulation switch cabinet is used to place
The bus-bar room of bus is also filled with SF6 insulating gas, current transformer is placed wherein, draught head is not present in both.
Shell 1 is the fire-retardant organic material shell using fire-retardant organic material.Further improve insulation effect.Ring bodies can
To be torus, square ring body or oval ring body.Conveniently it is fixed on the diverse location of gas insulation switch cabinet.It is wound with winding wire
The external diameter of the iron core 2 of circle and the difference of internal diameter are 3cm~5cm, and the external diameter of shell 1 and the difference of internal diameter are 3.1cm~5.5cm.Shell 1
It is smaller with the space that is wound between the iron core 2 of winding coil, reduce the volume of current transformer in itself.
Also include a housing, a bus of shell 1 and gas insulation switch cabinet is both secured in housing, also filled out in housing
Filled with SF6 insulating gas 3.It is both placed in the bus-bar room of gas insulation switch cabinet, further improves insulating properties.
Winding coil is the copper conductor winding coil that copper conductor is made.The cost of copper conductor is low, good conductivity.Copper conductor is excellent
Elect copper round wire as.Copper conductor outer surface is coated with layer of metal zinc.Zinc hardly changes in dry air, plays U.S.
Sight, antirust etc. are acted on.Or, copper conductor outer surface is coated with one layer of insulated paint.The purpose of insulation can be reached, is saved into again
This.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
