Abstract

A kind of high-tension switch cabinet insulating part Leakage Current measures sensing device, and comprise insulating part, described insulating part overlaps the draining ring having conductive silicon rubber to make, described draining ring is connected with current sensor by wire.The utility model in use, by the effect of draining ring by Leakage Current drainage, be connected to measurement current sensor carrying out Leakage Current, and current sensor also can connect real-time monitoring system, realizes Real-Time Monitoring by wire.The utility model overlaps draining ring and does not have an impact to insulating part itself on insulating part, and the life-span is longer, can Long-Time Service, install detect all very convenient.

Description

A kind of high-tension switch cabinet insulating part Leakage Current measures sensing device
Technical field
The utility model relates to a kind of high-tension switch cabinet insulating part Leakage Current measurement mechanism.
Background technology
Common switch cubicle its inner insulating part installed that is in operation can produce the weak electric field responded to by high-voltage electric field, generally the little electric field of this induction can not cause large impact to equipment and operating personnel, but, after the insulating part installed is aging or after employing insulating material inferior, larger leakage current will be produced, when leakage current is greater than 0.5mA, insulating part accelerated deterioration will be produced and affect its insulating property, insulating part can be caused time serious to puncture and discharge, and switching devices causes very large harm.Therefore, on-line measurement insulating part being carried out to leakage current is just very necessary.Usually, the method measuring leakage current is at a kind of tinfoil film of insulating part surface mount, connecting with wire is directed in reometer by its leakage current again, and the drawback of this method is the insulating property that tinfoil film can affect insulating part itself, can not Long-Time Service.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing high-tension switch cabinet insulating part Leakage Current measurement mechanism, the utility model provide a kind of can Long-Time Service and do not affect the high-tension switch cabinet insulating part Leakage Current measurement mechanism of the performance of insulating part own.
The technical scheme in the invention for solving the technical problem is: a kind of high-tension switch cabinet insulating part Leakage Current measures sensing device, comprise insulating part, described insulating part overlaps the draining ring having conductive silicon rubber to make, described draining ring is connected with current sensor by wire.
Further, described draining ring is made up of several cell stripes hinged successively.
Further, the cell stripes described in every bar is hollow.
The utility model in use, by the effect of draining ring by Leakage Current drainage, be connected to measurement current sensor carrying out Leakage Current, and current sensor also can connect real-time monitoring system, realizes Real-Time Monitoring by wire.
The beneficial effects of the utility model are: on insulating part, overlap draining ring do not have an impact to insulating part itself, and the life-span is longer, can Long-Time Service, install detect all very convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, a kind of high-tension switch cabinet insulating part Leakage Current measures sensing device, comprises insulating part 1, and described insulating part 1 overlaps the draining ring 2 having conductive silicon rubber to make, described draining ring 2 is connected with current sensor 3 by wire.
The utility model in use, by the effect of draining ring 2 by Leakage Current drainage, be connected to measurement current sensor 3 carrying out Leakage Current, and current sensor 3 also can connect real-time monitoring system, realizes Real-Time Monitoring by wire.
Described draining ring 2 can be made up of several cell stripes hinged successively, is convenient to suit.Cell stripes described in every bar all can be set to hollow, is more conducive to the measurement of Leakage Current.
