Abstract

The present invention relates to an interlock device of a ring main unit, and more particularly, to an interlock device of a ring main unit in which a fuse cover can be closed in interlock with a cable cover. An interlock device of a ring main unit according to an embodiment of the present disclosure may include an interlock frame (20) provided in part of the ring main unit, a cam (30) on part of which an engaging portion (32) is protruded and formed and on the other part of which a slit (31) is formed, rotatably provided within the interlock frame, an operating plate (40) an end of which is coupled to the slit to perform a vertical movement, and a spring (50) an end of which is fixed to part of the cam to store an elastic force due to the movement of the cam.

Description

technical field [0001] The present invention relates to an interlocking device of a ring main unit, and more particularly, to an interlocking device of a ring main unit in which a fuse cover can be interlockingly closed with a cable cover. Background technique [0002] Generally speaking, as a device used to monitor, control and protect electrical systems configured to transmit and distribute electricity to consumers through transmission and distribution, a Ring Main Unit (RMU) can be configured with a Components of circuit breakers, switchgear, grounding and conductors in insulated structures. [0003] figure 1 A ring main unit according to the prior art is shown in , and figure 2 shown in the figure 1 configuration in which the fuse cover and cable cover are removed. The fuse cover 2 and the cable cover 3 are provided on the front surface of the ring main unit 1, and various devices such as circuit breakers, switches, cut-off switches, earthing switches, etc. are acco...
