BUSHING CONVERTER
Document Type and Number:
Japanese Patent JPH04219909
Kind Code:
A
Abstract:
PURPOSE: To pass through a current in a high potential in an insulation state by embedding a duct pin and an exciting coil for measurement in an insulation body, electrically connecting the exciting coil for the measurement respectively and by forming a flat bottom part in a sealed state to the bushing of one end of the duct pin. CONSTITUTION: The bar-shaped duct pin 5 formed by conductive metal and the exciting coil 6 for the measurement for detecting the increase speed of the current flowing through the duct pin 5 are embedded in the insulation body 3, the exciting winding 6 for the measurement is electrically connected respectively, an opening part for electrically connecting both ends of the duct pin 5 is provided and the insulation body 3 is provided with a sealable flat bottom part 16 in the bushing at one end of the duct pin 5. A bush 17 for connection provided with a connection pin is installed to the outer wall of the insulation body 3 so as to electrically connect the exciting winding 6 for the measurement and the electric contact piece of an external connection member is engaged with the bush for the connection by using a screw for instance.
