The invention discloses a cable shearing device for
relay protection. The cable shearing device for
relay protection comprises a base, the lower surface of the base is provided with an antiskid pad, the top of the base is provided with a coil fixing
assembly, the coil fixing
assembly consists of a fixed disc, a rotating shaft, a baffle disc, a sleeve, a first adapter, a second adapter, and a
lantern ring, single wire fixing assemblies are symmetrically arranged on one side of the coil fixing
assembly, each single wire fixing assembly is composed of a fixator, a connecting block, a fixing block, a first spring, a check block, an installation plate, a second spring and a pressing block, and a shearing assembly is arranged between the two single wire fixing assemblies. The cable shearing device for
relay protection can achieve the advantages that a trapped cable can be conveniently installed on the rotating shaft, the
cutting difficulty is reduced in the cable
cutting process, time and labor are saved, a single cable can be conveniently fixed, and equipment is stable in the shearing process.
