Description

TECHNICAL FIELD [Apparatus for indirectly checking of Power line availability, System for indirectly checking of Power line availability and Driving thereof]

The present invention relates to an indirect live wire message inspection device, an indirect live wire message check system, and a driving method thereof, and more particularly, to an indirect live wire message check device capable of fixing a camera, an indirect live wire message check system, and a driving method thereof. About.

Diagnosis methods for power distribution facilities include high frequency, ultrasonic, thermal imaging, telescope, direct live wire inspection, and visual inspection.

High-frequency, ultrasonic, and thermal imaging diagnostics use expensive diagnostic equipment to indicate electrical and mechanical defects in equipment with a specific signal or temperature. However, in order to accurately check whether the equipment is actually defective, a high magnification telescope inspection (optical inspection) and a high magnification camera inspection must be additionally performed.

In spite of the additional inspection using the camera, there is still difficulty in diagnosing the upper part of the equipment and the part that is partially obscured, that is, about a third of the equipment.

In order to solve this problem, the inspection is carried out in a way that an operator directly approaches the extra-high voltage power line using a live line work vehicle and performs an inspection for each live line machine.

However, in the inspection of each live line, diagnosis in a complex distribution line is very dangerous because the operator must perform work close to the extra high voltage line while the power of the extra high voltage power line is turned on. Due to this risk, the transition to indirect live wire construction is being promoted instead of the direct live wire construction method.

The live wire inspection using the direct live wire method should be carried out by a live wire qualification holder. Since it is necessary to inspect it directly close to the power line, it is necessary to have a protective light, so the speed is poor. In addition, the cost paid to the worker for direct live work is also expensive. Each year, the number of inspections for each live line to prevent breakdown of distribution lines reaches about 10,000, which in turn consumes a lot of budget.

In order to solve such a problem recently, the aerial diagnosis inspection method using drones as a means to replace the direct live line message inspection method (2011). A method of inspecting distribution lines using robots (2009) has been proposed.

However, if a drone is used, the cost of the drone is high, and there is a possibility of a safety accident, such as a risk of a power outage in the event of a collision or a fall due to inadequate operation. In addition, even in the case of inspection of distribution lines using robots, the purchase price of the robot is expensive and there is a disadvantage that a live line work is required directly when mounting on the line, and thus the utilization is not actively performed.

On the other hand, the live wire work in which the power distribution work is performed on the overhead distribution line with uninterrupted power includes a straight live wire construction method and an indirect live wire construction method.

In the direct live wire method, a worker wearing protective equipment such as special high-pressure rubber gloves directly touches the overhead power distribution line in the state of being energized to perform the distribution work.

In the indirect live wire method, the electric power distribution work is performed without direct contact with the overhead distribution line, which is in the state of being energized, by using a rotor stick (insulation control rod). In recent years, from the viewpoint of improving the working environment and pursuing essential safety shoes, the transition from the direct live wire method to the indirect live wire method has been made.

The rotor stick can be attached to and detached from various tip tools for power distribution work at the tip. Using this tool, the operator can cut or connect the overhead distribution line.
