Abstract

PURPOSE: To eliminate influence of instantaneous power interruption and to prevent development of power interruption due to erroneous connection when performing maintenance, inspection, replacement of fault locator and recovery work of distribution line, by providing tow transistor additionally.
CONSTITUTION: When performing maintenance, inspection, replacement of fault locator or recovery work of distribution line, the handle is brought to direct transmit position then switches SW4, SW5 are opened and SW1-SW3 are closed while timer circuit 18 is disconnected and throw-in command is provided to section switch 14 only from power source switching circuit. Consequently transistor TR1 is turned on while TR2 is turned off when source side voltage exists while TR2 is turned on when load side voltage exists thereby it is self held to switch contact X2c thus to throw in section switch 14. Consequently instantaneous interruption at source side causes no influence while inconvenience due to erroneous connection of adaptor cable 19 during replacement of locator and be prevented.
