Abstract

See full text

A method for processing an interphase short circuit is provided, including: when a two-phase or three-phase interphase short circuit occurs in a line, maintaining a fault phase of the line to be conducted and tripping off the remaining fault phases, and artificially grounding another fault phase connected to the fault phase or directly utilizing an existing grounding point; connecting a neutral point or a charged phase of a three-phase ineffectively grounded power supply system other than the fault phase to the ground, so as to form a closed loop with the fault phase and generate a current, and detecting a current duration by a controlled switch. When a certain controlled switch reaches a trigger condition and cuts off the line, a fault is cleared.
