Description

Construction Protective Assembly for Indirect Hot-Line Work The present invention relates to a protective structure for construction to apply indirect live-line work, and more specifically, to a protective assembly for construction to apply indirect live-line work that can be easily installed and removed using an indirect live-line tool to minimize the position of the protective cover within the creepage distance of LP insulators and polymer suspension insulators at a construction site. Construction protective devices may be installed on power distribution lines to prevent safety accidents or line failures caused by workers or work equipment coming into contact with the power distribution lines when construction work, etc., is being carried out near the power distribution lines. In this case, since the building protective device cannot be installed on the wiring using indirect live-line tools due to structural issues, it may be applied so that a worker installs it directly. Furthermore, as shown in Fig. 1, the building protective cover cannot provide protection for the indirect live-line method for the branch ring portion, so the bushing portion of the pole-mounted transformer may be exposed. In addition, as shown in Fig. 2, the protective covering for construction cannot structurally provide protection for the branch sleeve portion for indirect live-line work and can be left exposed. In addition, as shown in Fig. 3, the protective covering for construction cannot structurally provide protection for the indirect live-line method for the branch ring cover and can be exposed as is. Figures 1 to 3 are field photographs illustrating the state in which a protective structure for indirect live-line work is installed. FIG. 4 is a configuration diagram illustrating an insulator protection cover module in a building protection assembly for indirect live-line work according to the present invention. FIG. 5 is a configuration diagram illustrating the side and front views of an insulator protection cover module in a building protection assembly for indirect live-line work according to the present invention. Figure 6 is a field photograph showing the insulator protection cover module installed on an LP insulator in a building protection assembly for indirect live-line work according to the present invention. FIGS. 7 and 8 are exemplary configuration diagrams for explaining the cover position of the insulator protection cover module in the creepage distance of the LP insulator in a building protection assembly for indirect live-line work according to the present invention, compared to the conventional method. FIG. 9 is a configuration diagram illustrating a dead-end protection cover module in a protective assembly for construction for indirect live-line work according to the present invention. FIG. 10 is a configuration diagram illustrating the folded side and unfolded front of a dead end protection cover module in a construction protection assembly for indirect live-line work according to the present invention. FIG. 11 is a field photograph showing a dead-end protection cover module installed on a polymer suspension insulator in a building protection assembly for indirect live-line work according to the present invention. FIGS. 12 and 13 are exemplary configuration diagrams for explaining the cover position of the dead-end protection cover module in the creepage distance of a polymer suspension insulator in a building protection assembly for indirect live-line work according to the present invention, compared to the conventional method. Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the attached drawings. A protective assembly for construction for indirect live-line work according to one embodiment of the present invention may include an insulator protective cover module (100) for protecting an insulator and a dead-end protective cover module (200) for protecting a polymer suspension insulator, as shown in FIGS. 4 to 13. That is, the above-mentioned insulator protective cover module (100) comprises an insulator protective body (110), an insulator mounting hook (120), an insulator clip hook hole (130), and an insulator fixing clip (140), as shown in FIGS. 4 to 8. At this time, the above-mentioned insulator protective body (110) is a thermoplastic elastic body that wraps around the upper part of the LP insulator, and two symmetrical bodies are joined by an ultrasonic welding method, and the two bodies can be folded to correspond to each other so as to easily wrap around the upper part of the LP insulator. Referring to FIGS. 7 and 8, unlike a conventional configuration in which an insulator protective cover encloses the entire shed of an LP insulator, in the case of a flexible distance extending from the upper shed S0 to the lower shed S6 of an LP insulator, the electric field is concentrated in the shed S1 to shed S2 section. It is desirable to form the heigh
