Title:
SWITCHING APPARATUS FOR GAS INSULATED SWITCHGEAR, AND GAS INSULATED SWITCHING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/199326
Kind Code:
A1
Abstract:
The present invention solves the problem that, for a switching apparatus tank, when a mechanism for transmitting a drive force to adjacent phases is to be constituted, a plurality of insulation components, bolts, and pins are used, and thus, the assembly operations of mounting and connecting the same inside a sealed container partitioned into small spaces is difficult to perform, requiring a considerable amount of work. This switching apparatus obtains a phase-to-phase coupling mechanism provided with the functions of insulating and supporting the switching apparatus, and guiding of mobile blade movements.
The switching apparatus comprises: switching apparatus blades for multiple phases, each for performing three-position switching among ON, OFF, and GROUND via a rotating axis; and a phase-to-phase coupling mechanism for supporting the switching apparatus blade of each phase in an insulated state from each of the other phases and each of the other grounds while causing the switching apparatus blade of each phase to be coupled to, and move together with, one another. The phase-to-phase coupling mechanism is constituted from mating couplings comprising an insulating material including a large diameter endless frame body and a small diameter endless frame body fitting into one another while each of the mating couplings is disposed on the same axis line.
