Abstract
PURPOSE:To detect the charge voltages of insulators safely with high accuracy in a detector for defective insulators having insulation characteristics cylindrical rollers moving on insulators by making a voltage divider freely movable and fixable to and at measuring positions. CONSTITUTION:A moving body 3 has two rows of roller groups 4, 4' arranged with plural pieces of insulation characteristic cylindrical rollers 20 consisting of electrical insulating materials in parallel to a plate shape, and moves by rotating on duplex insulators 1, 1'. A voltage divider 6 is mounted between the insulators 1 and 1' below an intermediate part 5. An optical voltage sensor 7 is connected to one end of the divider 6 and an expansion type insulation control rod 8 to the central upper part of the body 3 via a control rod connecting part 17. Contactors 12 that contact the insulator set at a right angle thereto are mounted rotatably to both ends of the voltage divider, thereby measuring partial voltages at the measurement point P of insulator fitting 2. The output of the voltage divider is fed to a measuring device via an optical voltage sensor 7 by means of an optical cable or the like and therefore the charge voltages of the insulators are measured with high accuracy without receiving faults such as electromagnetic induction.
