Answer :

Operation of Horizontal Break Isolator:

image

1) Fixed female contacts of metal are supported on stack of insulator. 2) Male contact rod is connected to central insulating support which can be moved to have horizontal movement of male contact for opening or closing into the female contacts. 3) The movement of the rod and its support may be done manually, electrically or pneumatically by operators. 4) The operating mechanism disengages or engages the rod into a female contact for closing and opening operation of isolator. 5) The male contact‟s movement is horizontal and hence this type of isolator is named as horizontal break isolator. 6) The assembly is supported on galvanized steel channel or steel frame. The moving male contact can be move through 90o.
