Description

A pin feeder capable of installing M-pins of insulators with electricity

technical field

The invention relates to the technical field of power transmission line maintenance equipment, in particular to a pin feeder capable of installing live insulator M pins.

Background technique

In overhead transmission lines, there are many cases where the M pins at the bowl heads of the suspension insulators come out, which seriously threatens the safe and stable operation of the lines and needs to be resolved in time. Now most of them adopt the operation method of power outage maintenance, and the application for power outage is cumbersome, time-consuming and labor-intensive. In addition, since the overhead transmission line operates in the natural environment for a long time, the insulators are inevitably affected by external environmental conditions, resulting in reduced or lost insulation performance. In order to ensure the reliability of the safe operation of the line, the ground potential operation method is often used to replace the insulator. During the live replacement of pollution-resistant insulators, due to the influence of factors such as the type of porcelain bottle, hardware (mainly referring to the opening direction of the bowl-head hanging plate), work tools, etc., when encountering pollution-resistant insulators with large skirts and deep ball ends , The skirt of the insulator blocks the removal and installation of the M pin by general equipment, which is inconvenient for the operation of the ground potential operation method, and the equipotential operation method must be used for operation. It takes a long time to complete the work, and it is impossible to complete the operation if special hardware is encountered.

When replacing the straight-line string insulators, when the opening of the bowl-head hanging plate is perpendicular to the line direction, the general M-pin pick-and-place equipment is powerless and can only be replaced under power failure conditions. When limited by the structure of the pole tower, when the combined gap does not meet the requirements of the safety regulations, the equipotential operation method cannot be used, and the only choice is to replace it with a power failure.

To sum up, it is particularly necessary to design a pin feeder that can install the M pin of the insulator live.

Ground potential operation method: The operator maintains the same potential between the human body and the earth (or tower), and contacts the electrified body through insulating tools. At this time, the relationship between the human body and the electrified body is: earth (or tower) person → insulating tool → electrified body.

Intermediate potential operation method: the potential of the human body is a suspended potential between the ground potential and the potential of the charged body. He requires the operator to keep a certain distance from the charged body and the ground. At this time, the relationship between the human body and the charged body is: earth (or tower) → insulator → human body → insulating tool → charged body.

Equipotential operation: The operator maintains the same potential as the charged body (wire). At this time, the relationship between the human body and the charged body is: charged body (human body) → insulator → earth (tower).
