Description

[0001] Apparatus for Defected Porcelain Insulators in Transmission Lines [

More particularly, the present invention relates to a transfer failure detector which can accurately detect a defective insulator regardless of the length of the insulator and improve the convenience of the detection operation.

At present, 154kV, 345kV and 765kV are used as domestic transmission voltage. Insulators, which are insulators, are used to connect the steel towers and conductors in the processed transmission, and the insulators are largely divided into magnetic insulators and polymer insulators. In Korea, magnetic resonators are used in 154kV, 345kV, and 765kV transmission towers, except that some polymer insulators are used in the 154kV transmission tower.

In order to confirm whether or not the insulator functions properly as an insulator, a defective magnetic field detection operation is periodically performed.

On the other hand, the defective magnetism detection operation of the 154 kV transmission tower is performed by connecting the voltage-resis- tant detector to the end of the insulating bar, and measuring the sharing voltage and insulation resistance at the ends of each insulator. In addition, in the 345 kV transmission tower, the detector is connected to the end of the insulating bar, and the detector is closely contacted with the detector from the upper end of the sensor to the lower end to detect the insulator by the phase angle have. In this case, the defective magnetic detector of the transmission tower is composed of a set of two persons in a live state. In this case, the measurement person performs a measurement by attaching the defective insulator detector to a hot stick end on a steel tower with a measuring tower.

At 345kV, an exfoliation bar having a fixed length of 4 ~ 5m is used. However, there is an error in the measured value depending on the skill of the measurer and the degree of adhesion between the insulator and the detector. In addition, there is a problem that the fatigue of the worker is large because the operator has to work manually for a long period of time while holding the rake rod attached with the detector during the measurement by the measurer. In addition, there is a problem that the bent bar with the detector mounted thereon is formed of a polymer material and is bent at the time of use, and in the case of a barrel having a certain length or longer, that is, the bent bar length, it is difficult to detect the defective insulator by the present method.

In addition, there is no method for detecting a faulty insulator in a 765 kV transmission tower, which is the highest voltage in Korea, where the length of the insulator is 8 to 10 m.
