The invention relates to the technical field of power monitoring system test terminals, and discloses a portable test terminal of a network security power monitoring system, which comprises a shell I. A terminal is fixedly mounted at the left end of the outer wall of the shell I. A touch screen is rotatably connected to the upper end of the left side of the outer wall of the terminal. A key is fixedly installed on the left side of the outer wall of the terminal, a middle block is fixedly installed at the front end of the outer wall of the first shell, and a second shell is fixedly installed at the front end of the outer wall of the middle block. A locking screw can slide back and forth to drive a sliding block to slide back and forth, when a sliding base slides back and forth, a first rotating shaft can be driven to move back and forth, so that a first rotating disc is driven to slide back and forth, the position of the sliding block can be locked by tightening the locking screw, and therefore ...

The invention discloses a distribution line inter-phase short-circuit fault property identification method and system based on injection voltage characteristics, and the method comprises the steps: injecting a voltage detection signal with a specific frequency and amplitude between a fault phase and a non-fault phase of a distribution line after a controllable voltage source receives protection action information and fault phase information of a line protection device; and the line voltage amplitude characteristics of the detection signal between the two fault phases are detected in real time, so that the fault property is identified. The controllable voltage source is utilized to inject the detection voltage signal into the power distribution system, fault characteristics are stable, fault property identification is carried out in combination with interphase voltage amplitude characteristics monitored in real time, the identification result accuracy is high, high voltage and current sensors ...
