The invention discloses a power distribution network feeder terminal unit. With the power distribution network feeder terminal unit adopted, the problem of relatively low automation performance and incapability of realizing fast fault detection fast of an existing jsh can be solved. The power distribution network feeder terminal unit is characterized in that the first input end of a first controller is connected with the output end of a sensor, the second input end first controller is connected with the output end a mechanical characteristic detection sensor; the first output end of the first controller is connected with the input end of a permanent magnetic actuator, and the second output end of the first controller is connected with a communication module; the output end of the permanent magnetic actuator is connected with the input end of a feeder switch; the output end of the feeder switch is connected with the input end of the mechanical characteristic detection sensor; and a power source is connected with the first controller and the permanent magnetic actuator. The automation performance of the feeder terminal can be realized; fault detection efficiency can be improved; and on-line monitoring on the mechanical characteristics of the body of the feeder switch can be realized.
