Description

Apparatus for Defected Porcelain Insulators in Transmission Lines

The present invention relates to an apparatus for detecting defectives for power transmission, and more particularly, to an apparatus for detecting defectives for transmission that can accurately detect defectives regardless of the length of an insulator and improves the convenience of the detection operation.

Currently, 154kV, 345kV and 765kV are used as voltages for domestic transmission. In overhead power transmission, insulators, which are insulators, are used to connect pylons and conductors, and insulators are largely divided into magnetic insulators and polymer insulators. In Korea, porcelain insulators are used in 154kV, 345kV and 765kV transmission towers, except that some polymer insulators are used in 154kV transmission towers.

In general, in order to check whether the insulator functions properly as an insulator, a defective magnetic insulator detection operation is periodically performed.

On the other hand, in the detection of defective magnetic insulators of a 154kV transmission tower, a voltage resistance type detector is connected to the end of an insulating rod, and the shared voltage and insulation resistance of both ends of each insulator are measured to determine whether the insulator is positive or negative. In addition, in the detection of defective insulators of the 345kV transmission tower, the electric field detector is connected to the end of the insulating rod, and the measurer attaches the detector from the top to the bottom of the insulator and detects it manually. have. The detection of defective magnetic insulators of the power transmission tower is performed in a pair of two in a live wire state, and for measurement, a measurer climbs the tower and attaches the defective insulator detector to the end of a hotstick in the pylon to measure.

At 345kV, an insulating rod having a fixed length of 4 to 5m is currently used, but an error in the measured value is occurring depending on the work skill of the measurer and the degree of adhesion between the measuring insulator and the detector. In addition, there is a problem in that the operator fatigue is large because the measurer has to manually work for a long time while holding the insulating rod to which the detector is attached while measuring. In addition, there is a problem in that the insulating rod to which the detector is attached is formed of a polymer material and is bent during use.

In addition, there is no way to detect bad insulators in the 765kV transmission tower insulators, which is the highest voltage in Korea where the length of the insulators is 8 to 10m.
