Problems solved by technology

[0007] However, in the related art ring main unit 10, the interlock device is not provided between the circuit breaker 11 and the disconnector 13, and for this reason, even when the circuit breaker is in the closed state, the handle can be inserted into the After being inserted into the hole 13a, the state of the breaker 13 is controlled by rotating the handle 20
[0008] In addition, if the breaker 13 having no load switching function is operated while the circuit breaker 11 is in the closed state, a large impact is applied to the ring main unit 10, and for this reason, the ring main unit 10 is largely damage
[0009] Furthermore, if the breaker 13 is operated while the circuit breaker 11 is in the closed state, an accident of negligence occurs in use, and for this reason, there is a great risk of loss of life

Abstract

An interlock apparatus of a ring main unit is provided. The interlock apparatus of the ring main unit may change a rotational motion of the shaft included in the circuit breaker to a rectilinear motion, and thus, the insertion hole may be opened or closed according to a closed or cutoff state of the circuit breaker. Accordingly, in the closed state of the circuit breaker, the control of a state of the disconnector is prevented.

Description

technical field [0001] The present disclosure relates to an interlock of a ring main unit, and in particular, to an interlock of a ring main unit that enables a state of a breaker to be controlled based on a state of a circuit breaker included in the ring main unit. Background technique [0002] Generally speaking, a ring main unit is a device for monitoring, controlling and protecting an electrical system for receiving and distributing electrical energy supplied from an electrical energy distribution device. The ring main unit is constructed to have an array, in which circuit breakers, power connection devices, grounding, conductors, etc. are included in the SF 6 Gas-tight and insulated structure. [0003] The ring main unit includes circuit breakers, load switches, fuses, disconnectors, etc. Cable covers are detachably attached to the RMU to protect individual circuits. [0004] figure 1 is a front view showing a state in which the cover is removed from the prior art r...
