The status of the recloser is also reflected by a microswitch connected to the control electronics. The electronic circuit board where the microswitch is fitted has no active elements which dramatically improves impulse immunity. The main circuit bushings are manufactured from UV stable polymer and have a silicone rubber bushing boot to provide the required creepage distance. The magnetic industrial actuators are operated from stored energy charged industrial capacitors located in the RC control cubicle. There is a rating plate located in the base of the tank that provides tank rating details in accordance with the requirements of ANSI C37.60. There is an earthing point on the side ofthe tank. The 200 Series OSM is supplied with cable connectors on each bushing. These are made from tin plated brass and can take cable sizes up to 260mm2. The cross sectional diagram below details the OSM tankconfiguration and main components. |
