Three-phase four-wire household line device on low-voltage line pole

Abstract

The invention relates to a three-phase four-wire drop wire mounting device on a low-voltage line pole. The device comprises an arc-shaped insulating panel matched with the low-voltage line pole. The left side of the insulating panel is vertically provided with a conductive A-phase wiring post and a conductive B-phase wiring post, the right side of the insulating panel is vertically provided with a conductive C-phase wiring post and a 0-phase wiring post, one side wall of each wiring post is provided with multiple wiring grooves in the vertical direction, the wiring grooves of the A-phase wiring post and the wiring grooves of the B-phase wiring post are leftward, the wiring grooves of the C-phase wiring post and the wiring grooves of the 0-phase wiring post are rightward, the wiring grooves in the topmost portions of the wiring posts are connected with a main incoming line, and other wiring grooves of the wiring posts are connected with branch outgoing lines. According to the device, an original multiple low-voltage branch line layout mode is changed into a distribution type mode through three-phase drop wire mounting devices on the low-voltage line pole, so that line layout is attractive and elegant, stress is uniform, insulation of lines is not damaged, cost is saved, and power-up on the pole and power supply are safe and reliable.

Description

technical field [0001] The invention relates to a three-phase four-wire household wire device on a low-voltage line pole. Background technique [0002] Existing low-voltage household line lines, because low-voltage users continue to apply for meter installation by household, when the system power enters the customer's electric energy meter, when the customer's incoming line is introduced due to the restrictions of the environment and surrounding conditions, it can only be continuously connected from the low-voltage line. In this way, the original intact low-voltage line insulation and line tension are greatly damaged, often resulting in accidents such as power outages and burning of household appliances caused by poor contact of live wires or neutral wires. At the same time, low-voltage lines form a cobweb-like layout due to multiple customer access lines, which affects the appearance, destroys people's vision, and affects the normal maintenance and repair work of the lines....

[0002] Existing low-voltage household line lines, because low-voltage users continue to apply for meter installation by household, when the system power enters the customer's electric energy meter, when the customer's incoming line is introduced due to the restrictions of the environment and surrounding conditions, it can only be continuously connected from the low-voltage line. In this way, the original intact low-voltage line insulation and line tension are greatly damaged, often resulting in accidents such as power outages and household appliances being burned due to poor contact of live wires or neutral wires.

At the same time, the low-voltage lines form a spider-like layout due to multiple customer access lines, which affects the appearance, destroys people's vision, and affects the normal maintenance and repair work of the lines.
