The invention provides a low-
voltage complete set power distribution cabinet
fault indicator, and belongs to the technical field of electrical detection. The indicator comprises an indicator host, a
short circuit sensor, a power supply cable, a grounding sensor and a sensing cable. The indicator host is connected with the
short circuit sensor and the grounding sensor through the sensing cable; andthe
short circuit sensor is nested on the outer surface of the
branch cable of the power supply cable. The low-
voltage complete set power distribution cabinet
fault indicator is provided with a fixing bolt rod, an internal hexagonal
wrench is used for screwing an internal screw rod to push a sliding plate and a power connection block to get close to each other until the sliding plate and the power connection block are attached, so that the second
electromagnetic coil is powered on to generate a
magnetic field and attract the permanent
magnet and the iron box under the action of magnetic fieldattraction; and the fixing bolt rod is synchronously driven to be clamped in the open groove to be fixed, so that the fixing bolt rod can quickly buckle and fix the annular plate after the second
electromagnetic coil is powered on, and the disassembly and
assembly efficiency and the fixing stability of the annular plate during use of the annular plate are greatly improved.
