Description

[0001] The present invention relates to an automatic tracking system failure in distribution lines,

The present invention relates to a system for automatically tracking disturbance by a distribution line, and more specifically, it is possible to reduce an occurrence of an electrical fault by detecting an electrical defect in an uninterruptible state at the time of inspection of an electrical facility. So that it can prevent human accidents in advance.

Generally, power facilities are required to be continuously monitored, removed from dangerous factors, and replaced with old facilities due to changes in the environment around the power lines and damage due to equipment failure.

For example, various instantaneous inspection methods are used to prevent breakdown of processing power distribution line equipment such as insulator failure, equipment failure, and connection failure. Typically, a power line instantaneous method , A live wire inspection method for measuring the sharing voltage by using a visual and fork type suspension type voltage measuring device by accessing live wire distribution equipment by using a live wire bucket truck in live wire state, An ultrasonic measurement method, a thermal imaging camera measurement method, and an instantaneous method using an RFI (Radio Frequency Interface) are used to prevent a failure of a distribution line.

On the other hand, it is practically impossible to visually measure the abnormality of the facility because the electric power facility is located at a distance of 10 m or more from the ground.

Since the live wire operator inspects the live wire bucket truck, it is possible to see the equipment at a close distance by the naked eye. However, in the case of a small space between the insulator and insulator, or a minute crack existing on the opposite side from the inspector It is very difficult to check, it takes a lot of time to check, and it is relatively inefficient because it is relatively expensive.

Although the ultrasonic measurement method currently judges the failure and position of the electric power facility subjectively by the hearing and judgment of the person, it requires a highly trained workforce in reading the defect, There is a problem that occurs.

Since the instantaneous method using the RFI is difficult to distinguish from the noise from the electric power facility due to the excessive frequency noise in the case of the downtown area or the dense area in the factory, it is impossible to accurately distinguish the faulty facility . In addition, since it is impossible to analyze the waveform, it is difficult to grasp the type of the fault and to grasp the degree of the fault.

In addition, although machinery facilities installed in various industrial sites are required to be constantly inspected and managed, there is a problem that it is very difficult to check and manage machinery facilities in a case where the installation space of the mechanical equipment is narrow and the noise is severe.
