Abstract

PURPOSE:To enable finding a deteriorated insulator safely and with good work ing efficiency by forming an electrode on top of the insulator and fitting both an electrode wire fracture detector and an indicator to the insulator. CONSTITUTION:When an insulator deteriorates and the porcelain part thereof is cracked, an electrode 4 formed in close contact with the porcelain of an insulator head 1 concurrently fractures, thereby interrupting a current flow to the electrode 4. A detecting circuit 8 detects the interruption of the current flow and an indicator 9 such as ECD operates, indicating the occurrence of fracture at a position such as the external surface of a cap fitting 2. It follows, therefore, that a worker can easily finds the deteriorated insulator using a telescope and the like under a steel twoer without climbing thereon for inspecting the condition of the deterioration.

(Prior art) Insulators that insulate and support power transmission lines are made of durable and stable porcelain, but because they are installed and used in harsh environments for long periods of time, Deterioration may occur due to shock, etc. Conventionally, in order to detect such deteriorated insulators, it was common for a worker to climb a steel tower and inspect each insulator for insulation deterioration using a defective insulator detector attached to the tip of an insulating rod. However, this conventional method has the disadvantage of being dangerous and unsafe because it requires operating a long insulating rod on the steel tower to bring the defective insulator detector into contact with the live insulator. . In addition, such conventional methods have poor work efficiency because they require climbing up each steel tower, and it is impossible to quickly discover defective insulators in the event of an accident.
