The main circuit is configured to be connected to and disconnected from a vertical bus bar 5 formed within the frame 1 together with an insulating cover 4 when the equipment unit is pulled out or inserted.

て一体に締付ける。 As shown in FIG. 2, the busbar configuration in such a closed switchboard is such that horizontal busbars 6 are arranged for each phase on the back side of an insulating support cover 7 formed in a convex shape, and are in contact with the main circuit section of the unit device. The vertical generatrix 5 is
It is placed on the front side of the insulating support cover 7.
The horizontal busbar 6 is intersected with an insulating support cover 7 interposed therebetween. Further, a protective cover 4 is provided on the front side of the insulating support cover 7 to prevent the vertical bus bar 5 from being exposed inside the panel. The in-phase connection between the vertical busbar 5 and the horizontal busbar 6 is performed through a conductive spacer 9 in an opening provided at the corresponding intersection, and they are tightened together with a tightening bolt 8.

よりスペーサ９を介して水平母線６と接続する。 As shown in FIGS. 3 and 4, the vertical bus bar has a protrusion 5a for engaging with the contact 10 of the main circuit disconnection section on the equipment unit side (not shown),
Further, both sides have flange 5b for engaging with the insulating support cover 7. A connection hole 5c is provided in the flat portion, and the tightening bolt 8 passing through the connection hole 5c is connected to the horizontal bus bar 6 via a spacer 9.

因となる。 In a horizontal busbar having such a configuration, the insulating support cover 7
Since the horizontal busbar 6 is always in contact with the vertical busbar 5
At the connection portion between the horizontal bus bar 6 and the horizontal bus bar 6, the thicknesses of the insulating support cover 7 and the conductive spacer 9 must be the same, and the thicknesses of the insulating support cover 7 and the conductive connection spacer 9 are required to be accurate. For this reason, if manufacturing errors in the manufacturing process or thermal expansion or thermal deterioration during long-term use of the insulator occur, contact failure may occur.

た母線装置を提供することにある。 It is an object of the present invention to improve conductive spacers that connect the front and rear conductors in a busbar device in which conductors are arranged in front and behind each other through an insulating material. In addition to preventing poor contact at the contact portion, the conductor other than the contact portion is not brought into direct pressure contact with the insulating support cover, and composite insulation consisting of insulation by the insulating support cover and an air or other insulating layer is achieved. It is an object of the present invention to provide a busbar device which improves the insulation effect and thermal deterioration of the insulator due to heat generation of the conductor.

The thickness Y of the conductive spacer 9a is made thicker than the thickness X of the insulating support cover 7 by Z. Therefore, as shown in FIG. 6, the horizontal busbar 6 is fixed by another support insulator 10, etc., and an air goat Z is formed between the vertical busbar 5' or 5'' of different polarity and the insulating support cover 7. arise.

上する。 Next, the functions and effects of the present invention will be explained. As shown in FIG. 6, the vertical busbar 5 and the horizontal busbar 6 are reliably connected by tightening bolts 8 via conductive spacers 9a. Therefore, there is no possibility of poor contact due to variations in the thickness of the insulating support cover 7.
Further, the insulation between different phases such as the vertical busbars 5', 5'' and the horizontal busbar 6 is a composite insulation of the insulation support cover 7 and the air goat or polyester insulation paper 11.
Even if cracks or thermal deterioration occur in the insulating support cover 7, the air goat or polyester insulating paper 1
1 maintains interphase insulation and improves insulation reliability.
