PURPOSE:To facilitate the recovery from an accident and improve the service by providing a display for displaying the operating condition of a breaker for breaking the accident of the distribution line, and arranging the equipments in each section of the system distribution of the distribution line. CONSTITUTION:A breaker 11 of a distribution line monitor and control equipment 10 is arranged in charge of an amount of two phase of a convert transformer 20 and an amount of three phase of a voltage detecting sensor 16 of the load side 4. The signal of an zero phase convert transformer 15, the convert transformer 20 and the sensor 16 arranged in the both ends of the breaker 11 are processed to be input to a protective relay 21, and a part of them is output to an operating unit 22 and a transmission passage 23. The display 12 arranged at the lower side of a case 13 can display the output, receiving the signal of the operating unit 22 and the relay 21. The accident current of the distribution line is broken by the breaker 11, and the operating condition of the breaker 11 is displayed by the display 12 arranged at the lower side of the case 13. This control equipment is provided in each section of the system distribution of the distribution line so as to facilitate the recovery from an accident and improve the feed service. |
