Description

Technology Field

[0001] The present invention relates to an insulating cover structure and installation method for the charging part of a cutout switch fuse holder, and more specifically, to an insulating cover structure and installation method for the charging part of a cutout switch fuse holder that enables complete insulation of the cutout switch and the charging part of the fuse holder by an indirect activation method. Background Technology

[0002] A cut-out switch is a protective device installed at the pressure end of a transformer used to transmit and distribute power from the power system to consumers, in order to protect the transformer from fault currents such as overcurrent and overload current generated at consumers.

[0003] Cutout switches have a problem where electric shock accidents and malfunctions occur due to contact by birds, the carelessness and lack of safety awareness of the general public, or frequent electric shock accidents and malfunctions caused by contact at urban construction sites, such as new building construction, or during the moving process using scaffolding.

[0004] In order to prevent such contact accidents, insulating covers are installed on the upper and lower parts of the fuse holder of the cutout switch, respectively; however, as shown in FIG. 1 and FIG. 2(a), these upper and lower insulating covers have a problem in that they cannot insulate exposed conductor parts, such as the hook eye of the guide rod fuse holder, due to their structure.

[0005] In addition, existing cutout switch insulation covers can only be installed using the diagonal line or direct live-line methods.

[0006] That is, referring to Fig. 2(a), the upper insulating cover is registered as a standard specification (ES) and is enclosed when the cutout switch is shipped, and due to the structure of being installed by inserting it into the lead wire, there was a disadvantage that it had to be installed only by diagonal wire work.

[0007] Referring to Fig. 2(b), the lower insulation cover is of non-standard specifications and is purchased and used by secondary offices to prevent safety accidents. Because it is a structure that wraps around the lower part of the cutout switch, it has the disadvantage of having to be installed only by the diagonal line or direct live line method.

[0008] Therefore, since existing upper and lower insulation covers cannot be installed via indirect live lines, if they are not installed during the initial installation of the transformation pole, there is a problem in that installation costs increase and there is always a risk of safety accidents when installing or replacing defective products to prevent safety accidents.
