Abstract
A combined sealed structure type current transformer comprises a current transformer body and a post terminal, wherein the current transformer body is a straight through current transformer, a cylindrical post terminal outlet arm extends out from the post terminal, the cylindrical outlet arm crosses over the current transformer body, a connecting part is arranged between the current transformer body and the post terminal and is of a concentric circle structure, the connecting part is located on the left side of the current transformer body, the current transformer body comprises an outer circle and an inner circle, and a conical protective sleeve is arranged between the combination surfaces of the inner circle of the current transformer body and the outer circle of the outlet arm. Due to the fact that the concentric circle type connecting part is arranged between the current transformer body and the post terminal outlet arm, connection between the current transformer body and the post terminal can be tighter, moisture is prevented from permeating into the post terminal at the connecting position, and using safety of the post terminal is guaranteed. Due to the adoption of the silicone rubber conical protective sleeve, water vapor is prevented from permeating into the post terminal, the insulation performance of the post terminal is guaranteed, and corrosion to the post terminal and the current transformer body caused by water vapor is avoided.
Description
Technical field
The utility model relates to a kind of power equipment, is specifically related to a kind of combined seal structure current transformer.
Background technology
Along with the whole nation continuing to increase with Voltage force, the operating pressure of power equipment is also in continuous lifting, the fine or not direct relation of power equipment operation the normal operation of national electric power transport, power equipment moves throughout the year in the open, such operational mode causes power equipment can be subject to the corrosion of rainwater, there is a large amount of aqueous vapors to enter in the middle of power equipment, such aqueous vapor can cause the decline of Electric Power Equipment Insulation ability, can not ensure the normal operation of power equipment, constantly declined the useful life of power equipment, increase the cost of operation power, can not be well for the people provide stable electricity consumption, be subject to the power equipment that aqueous vapor corrodes simultaneously, in running, also there will be the scene of electric leakage, electric leakage can cause the burning of power equipment, there is so very large potential safety hazard, once generation spontaneous combustion, consequence is hardly imaginable, serious threat is to resident's the security of the lives and property.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, a kind of combined seal structure current transformer of good seal performance.
The technical solution of the utility model is: a kind of combined seal structure current transformer, comprise current transformer and pole, described current transformer adopts straight-through current transformer, on described pole, be extended with pole line-outgoing arm, described pole line-outgoing arm is cylindric, described cylindric line-outgoing arm passes across current transformer, between described current transformer and pole, be provided with connector, described connector is concentric structure, described link is positioned at the left side of current transformer, described current transformer is divided into cylindrical and inner circle, between described instrument transformer inner circle and pole line-outgoing arm cylindrical faying face, adopt taper sheath.
Described taper sheath is silicon rubber taper sheath.
The end of described current transformer is provided with locating piece, and described locating piece blocks pole line-outgoing arm.
Advantage of the present utility model is: between current transformer and pole line-outgoing arm, be provided with concentrically ringed connector, can allow between current transformer and pole, be connected more tight, can not make moisture in the middle of junction penetrates into pole, protect the use safety of pole, adopt silicon rubber taper sheath can avoid steam to immerse in pole, protect the insulating capacity of pole, avoid the corrosion of aqueous vapor for pole summation current transformer, extend the useful life of pole, can absorb the internal stress causing because of variation of ambient temperature simultaneously, avoid this internal stress to cause that pole product structure damages, optimize the serviceability of pole.
