Abstract

PURPOSE: To make it possible to absorb errors in dimensions and thus hold the upper, lower and both side faces of conductors with reliability in the respective directions, by changing the volume of the spaces formed by the end faces of main projections, the side faces of subprojections and the side faces of the tips of subsupports through the shifts of the positions of main supports and the subsupports. CONSTITUTION: The upper and lower ends of conductors 6 are positioned in opposed upper and lower spaces 22, formed by the end faces of the main projections 19 on main supports 18, the side faces of the tips of subsupports 20, and the side faces of subprojections 21. Both side faces of the upper and lower ends of the conductors 6 are in contact with the end faces of the main projections 19 on the upper and lower main supports 18 and the side faces of the tips of the subprojections 20. The upper and lower end faces of the conductors 6 are in contact with the side faces of the upper and lower subprojections 21. Thus every face of the conductors 6 is fixed with reliability. When the main and subsupports 18, 20 are moved to vary the volume of the spaces 22, therefore, errors in the dimensions of these parts are absorbed, and thus the upper and lower end faces and both side faces of the conductors 6 are fixed in the respective directions with reliability.

In the case of the above-mentioned conventional conductor support device, the size of the conductor 6, the number of conductors constituting one phase, the inter-phase dimension, etc., differ depending on the switchgear, so it is necessary to design each time. Further, in order to absorb the error of each dimension, some allowance is required in the width dimension of the long groove 5, and in particular, a play occurs between the side surface of the long groove 5 and the side surfaces of both ends of the conductor 6, and the conductor 6 Is not fixed securely. Moreover,
The main and auxiliary supports 2 and 3 are large in size, heavy in weight, and it is difficult to attach the conductor 6. In consideration of the above points, the present invention can cope with various conductor sizes, the number of conductors constituting one phase, interphase dimensions, and the like, and absorb the error of each dimension to securely fix the conductors.
It is an object of the present invention to provide a conductor supporting device that can reduce the weight of main and auxiliary supports and easily attach conductors.

It is movably supported, and the upper and lower ends of the strip-shaped conductor in the front-rear direction are applied to the end faces of the main protrusion of the main support and the side faces of the tip of the sub-support so that both end faces of the conductor are Apply to the side of the sub-projection of the sub-support, insert bolts into the long holes of both rails on the outside of the main and sub-supports of the upper and lower, and screw the nuts onto the bolts. Since the conductors are supported via the respective lower and upper supports,
By changing the size of the space formed by the end face of the main protrusion, the side face of the sub protrusion, and the side face of the tip of the sub support by moving the main and sub supports, various conductor sizes can be obtained. The space can accommodate the number of conductors constituting one phase, the inter-phase dimension, etc., and this space absorbs the error in each dimension, and the upper and lower end faces and both side faces of the conductor are securely fixed from the direction of each face. . Further, the main and sub supports are made smaller and lighter, and the conductor can be easily attached.
