35kv post insulator intermediate phase automatic wire supporting device

Abstract

The invention discloses a 35kV post insulator intermediate phase automatic wire supporting device, relating to the technical field of power production and maintenance. A state display unit is installed on the outer surface of a power control box, an electric slide rail mechanism is installed in the middle of the interior of the power control box, a lifting mechanism is installed on a slide block of the electric slide rail mechanism, a lifting rod of the lifting mechanism is connected with a fixed support through a connecting rod, a wire fixing slot is formed in the fixed support, and two limit switches are respectively installed on the side walls of the power control box; a power supply unit supplies power to the lifting mechanism to control the lifting mechanism to propel lifting of the fixed support, meanwhile, the electric slide rail mechanism drives the fixed support to realize fine adjustment, and the support can be raised to lift a conducting wire during maintenance; after the maintenance, the support can descend to lower the conducting wire; the state display unit can display the motion state of the lifting mechanism; and the device can conveniently support the conducting wire, is convenient and fast in adjustment and high in working efficiency, and improves the safety.

Description

Technical field: [0001] The invention relates to the technical field of electric power production and maintenance, in particular to a mid-phase automatic wire support device for 35kV post insulators. Background technique: [0002] In the 35kV old-fashioned lines, the conductors are usually arranged in a triangular arrangement. In order to save cost, improve the safe and reliable operation of power transmission and equipment, porcelain cross arm is used. However, the 35kV transmission lines are located in hilly and mountainous areas with large spans, and inclement weather is prone to breakage of insulators and wire shedding, which affects the safe and stable operation of the line. Once the middle phase insulator is damaged and needs to be replaced, it will be difficult to lift the wire and restore it to its original position. In the process of replacing insulators, if the gear distance is too large, a single person cannot complete the wire homing operation; if relying on th...

Problems solved by technology

However, the 35kV transmission line is located in hilly and mountainous areas, with large spans, and inclement weather is prone to breakage of insulators and wire shedding, which affects the safety and stable operation of the line.

Once the middle phase insulator is damaged and needs to be replaced, it will be difficult to lift the wire and restore it to its original position

In the process of replacing insulators, if the gear distance is too large, it is impossible for a single person to complete the wire homing operation; if relying on the shoulders of workers at heights to support the wires, it will greatly consume their physical strength, and it is easy to cause the wires to slip from the shoulders to the cross arm, which can easily cause the wires to be damaged. Wear and tear; and high-altitude workers are susceptible to falling from high altitudes due to wire slippage, which is very dangerous

Moreover, the existing automatic wire support device cannot be fine-tuned during use, resulting in inconvenient use and a waste of time
