Abstract
And an insulating cover for a bushing terminal for covering a terminal bolt for connecting a cable to the terminal block, the cover including a cover body detachably coupled to cover the terminal block and the terminal block bolt, ; And a tracking preventing portion protruding from the inside of the cover body close to the head portion of the terminal block bolt. Thus, it is possible to provide an insulating cover for a bushing terminal which can reduce a tracking phenomenon.
Description
BACKGROUND OF THE
Generally, there is a bushing terminal exposed to a high-voltage transformer such as 22.9 kV or a lightning arrester, and an insulating cover for protecting the bushing terminal from the outside is provided.
As described above, the insulating cover for the bushing terminal has to be rigid so as not to be separated by an external force such as wind, and has been researched so as to maintain the airtightness so as to prevent the occurrence of an electric shock due to inflow of rainwater or the like.
One such conventional insulating cover is disclosed in Korean Registered Utility Model Registration No. 20-0384366.
1, the conventional insulation cover for a transformer is a cover which insulates a structure in which a high-
Accordingly, such a conventional insulating cover for a transformer can prevent tracking by keeping a distance of 20 mm or more between the terminal block bolt and the insulating cover, and by using the upper packing and the lower packing to maintain the airtightness to the cable and the insulator, Moisture and dust can be prevented from entering.
However, in the conventional insulation cover for a transformer, when an operator inserting the insulation cover mistakenly installs the narrow space in the insulation cover in the direction in which the
In addition, the conventional insulation cover for a transformer has a problem in that when the insulation cover itself is exposed to the outside for a long time, the insulation performance is weakened and the insulation phenomenon may occur.
Embodiments of the present invention are to provide an insulating cover for a bushing terminal that can prevent the erroneous mounting or the like of the operator during the insulating cover mounting work and reduce the tracking phenomenon.
Embodiments of the present invention also provide a bushing insulation cover capable of continuously maintaining insulation performance of an insulation cover even when exposed to the outside for a long time.
The insulating cover for a bushing terminal according to an embodiment of the present invention includes a terminal block coupled to one side of an insulator and an insulating cover for covering a terminal block bolt for connecting a cable to the terminal block, A cover main body detachably coupled to the main body; And a tracking preventing portion protruding from the inside of the cover body close to the head portion of the terminal block bolt.
The tracking preventing portion according to the embodiment of the present invention is formed to be close to the head portion of the terminal block bolt so as to approximate the distance between the tail portion of the terminal block bolt and the inner surface of the cover body.
According to an embodiment of the present invention, when the tracking preventing portion is provided in the tail direction of the terminal block bolt, the tracking preventing portion and the tail portion of the terminal block bolt contact with each other and interfere with each other.
The cover body according to the embodiment of the present invention includes an inner cover portion formed on the inner side to cover the terminal block and the terminal block bolt and an outer cover portion formed on the outer side of the inner cover portion with a space therebetween .
According to an embodiment of the present invention, an intermediate support member may be formed between the outer cover part and the inner cover part.
The intermediate support member according to the embodiment of the present invention may be characterized by being formed in a honeycomb or rod shape.
The cover body according to an embodiment of the present invention includes a cable packing member for supporting the cable and an insulator packing supporting member for supporting the insulator, a cable packing member hermetically provided between the cable and the cable packing supporting member, And an insulator packing member hermetically sealed between the insulator and the insulator packing supporting portion, wherein the cable packing member and the insulator packing member are made of a silicone material.
Embodiments of the present invention can provide an insulating cover for a bushing terminal that can prevent the erroneous mounting and the like of the operator during the insulating cover mounting work and reduce the tracking phenomenon.
In addition, embodiments of the present invention can provide an insulating cover for a bushing head which can continuously maintain the insulating performance of the insulating cover even when exposed to the outside for a long time.
