Abstract
The utility model relates to an insulating bushing. With the insulating bushing adopted, the problem of inconvenient use caused by a requirement for extra installation of a current transformer in current measurement of a cable bushing can be effectively solved. The insulating bushing includes an insulating sleeve body and a conductor; the conductor is arranged at the center of the insulating sleeve body; and the outer side of the conductor is spirally wound with a coil in the insulating sleeve body, wherein the coil is integrally casted with the insulating sleeve body. The insulating bushing of the utility model has the advantages of novel, unique, simple and reasonable structure, easiness in production, low cost, convenient use, excellent effect and innovativeness.
Description
Technical field
The utility model relates to a kind of insulating sleeve that inlet wire in power switchgear or outlet are used.
Background technology
Gas-filling cabinet in electrical power trans mission/distribution system, all cable sleeves of solid insulation cabinet only play insulation and electric action, also need to install in addition current transformer additional in the time that needs are measured electric current, use very trouble, and therefore, its improvement and bring new ideas is imperative.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of insulating sleeve, can effectively solve when cable sleeve need to be measured electric current and also need to install in addition current transformer additional, uses the very problem of trouble.
The technical scheme that the utility model solves is, comprises insulation body and conductor, conductor be installed on insulation body in intracardiac, conductor outside installs around in the shape of a spiral the coil that is cast into one with insulation body in insulation body.
The utility model novel structure uniqueness, advantages of simple, easily produces, and cost is low, easy to use, effective, is the innovation on cable sleeve.
Brief description of the drawings
Fig. 1 is part section front view of the present utility model.
Fig. 2 is stereogram of the present utility model (insulation body is cut open).
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Provided by Fig. 1,2, the utility model comprises insulation body and conductor, conductor 1 be installed on insulation body 2 in intracardiac, conductor 1 outside installs around in the shape of a spiral the coil 3 that is cast into one with insulation body in insulation body 2.
In order to ensure result of use, insulation body 2 is stretched out at the two ends of described coil 3, convenient connection.
When the utility model uses, the two ends of coil 3 are as binding post, be connected with AD converter, the conductor 1 that is contained in insulation body 2 centers passes through from coil central authorities, while having alternating current to pass through in conductor, the binding post at coil two ends has induced voltage, and this voltage becomes digital quantity through AD converter, can calculate according to this digital quantity and coil turn the size of current of passing through in conductor.This kind of sleeve pipe can be used for current measurement, relaying protection, charged demonstration, easily produces, and cost is low, easy to use, effective, can directly measure electric current, without installing in addition current transformer additional, is the innovation on cable sleeve, has good society and economic benefit.
