Abstract

The invention discloses a low-voltage line wiring device of a distribution network. The device comprises a wiring box body, wherein triphase main bus bars in trapezoidal step layout are arranged on the upper side in the wiring box body; triphase bus bar wiring boards are connected with the triphase main bus bars and extend to the upside; the triphase main bus bars are connected to an incoming portof an air circuit breaker and triphase electric meter bus bars that are located on the lower side and in trapezoidal step layout; the triphase electric meter bus bars are connected with a plurality of air circuit breakers; the air circuit breakers are connected with the wiring box body in an overhung manner; the air circuit breakers and the air circuit breaker are arranged sagittally; a leading-out terminal of the air circuit breaker is connected with user dynamic electric meters; leading-out terminals of the air circuit breakers are connected with user single-phase electric meters; the device further comprises a zero phase bus bar mounted in a right side wall of the wiring box body; the zero phase bus bar is connected with a zero phase electric meter bus bar via a wire; and the zero phase electric meter bus bar is connected with the air circuit breakers via wires. The wiring box body is high in heat dissipation performance, reasonable in space and good in man-machine effect, and facilitates the implementation of working such as load access and overhaul.

Description

technical field [0001] The invention belongs to the technical field of power distribution line equipment, and in particular relates to a low-voltage line wiring device for 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 power meters. Thus causing major safety hazards and problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a distribution network low-voltage line connection device to solve the above-mentioned p...
