Abstract

The invention discloses a support device of a low-voltage line wiring box of a distribution network. The support device comprises a bracket, wherein the bracket comprises a rear side fixing frame anda bottom connecting frame that are perpendicularly and fixedly connected; the rear side fixing frame is fixedly connected onto a wall; and strip-type holes connected with a box body are formed in thebottom connecting frame. According to the device, the wiring box body is supported by the bracket; the support mounting safety of the wiring box body is further guaranteed; the front end of the bracket extends out of the box body by a section; on the one hand, outgoing of bottom dynamic electric meters and single-phase electric meters is facilitated; on the other hand, the mounting of the box bodyand safe connection of a main incoming line are guaranteed; both hands of personnel are free when the personnel climb a ladder to perform operation such as operation and maintenance, first-aid repairand meter load access on the box body; the overhaul, mounting and dismounting of a distribution box by hanging an insulation ladder and standing are facilitated; the operation safety is higher; a man-machine effect is good; the working efficiency is improved; an altitude falling safety accident is effectively avoided; and the binding and anchoring, and secondary binding and anchoring of a safetybelt are facilitated.

Description

technical field [0001] The invention belongs to the technical field of power distribution line equipment, and in particular relates to a supporting device for a junction box of a low-voltage line of a distribution network. Background technique [0002] Due to urban construction planning, a large number of private buildings on both sides of commercial streets in some urban areas, county-level cities, and towns have not reserved access to power facilities. Power transformers, poles, overhead wires and other power facilities are installed on both sides of the road. After years of commercial development, all walks of life and various advertising doors will tightly wrap and package power facilities such as low-voltage power lines along the wall and energy meters. When the junction box is installed, it is located at a higher position above the advertising door, and the wall is relatively smooth. The relevant safety measures cannot be fixed, and there is a very high safety risk of ...
