Description

[Detailed explanation of the idea] The present invention relates to a conductor support device.

Copper or aluminum strips with a rectangular cross section are often used as conductors for large current busbar devices in power plants, substations, etc., and outdoor low-voltage, large-current busbars for power supplies for electric welding machines in shipyards, etc. .

The above-mentioned conductor is supported by the support device shown in FIG. 1 in order to be able to sufficiently withstand a large impact force due to a large current in the event of a short circuit accident, and external force due to a typhoon, earthquake, etc. That is, the conductor 3 is placed on the lower metal fitting 2 placed on the insulator 1 installed under the floor surface, the conductor 3 is sandwiched between the side metal fittings 4 on both sides, the upper parts of the side metal fittings 4 are connected via the spacer 5, and the The metal fittings and the lower metal fitting 2 are collectively fixed to the insulator 1.

The manner in which the conductor 3 is supported includes movable support that allows the conductor to slide in the middle of the conductor, and fixed support that does not allow the conductor to slide at the terminal end. In order to securely support a conductor using the support device shown in FIG. 1, it is sufficient to attach the side metal fittings in close contact with both sides of the conductor. However, in order to provide movable support, it is necessary to take sufficient care to create a predetermined gap between the side surface of the conductor and the side metal fitting.

The present invention was developed based on the above-mentioned circumstances, and an object of the present invention is to provide a conductor support device that can easily support a conductor in a movable manner.

In the present invention, the above object is achieved by providing on one surface of the lower metal fitting of the support device a protrusion having a width larger than the conductor width, preferably a width equal to the conductor spacing when the conductors are movably supported.

The details of the present invention will be explained below with reference to FIG. 2, in which the same parts as in FIG. 1 are given the same reference numerals. The lower metal fitting 2 placed on the insulator 1 has on one surface a protrusion 2a having a width equal to the distance between the side metal fittings 4 when movably supported. When the conductor is fixed and supported, the lower metal fitting 2 is placed on the insulator 1 with the side with the protrusions 2a facing downward, the conductor 3 is placed on the upper surface of the lower metal fitting 2, and the side surfaces are placed on both sides of the conductor 3. The side metal fittings 4 and the lower metal fitting 2 are fixed to the insulator 1 at once by abutting the metal fittings 4 and connecting the side metal fittings via the spacer 5.

On the other hand, in the case of movable support, the lower metal fitting 2 is placed on the insulator 1 with the surface with the protrusion 2a facing upward, and the conductor 3 is placed on the protrusion 2a. Therefore, the side metal fittings 4
are arranged with their lower ends in contact with the side surfaces of the protrusions 2a, and a spacer 5 and a washer 6 are placed between the upper ends.
The side metal fittings 4 and the lower metal fittings 2 are connected to the insulator 1 at once.

As mentioned above, according to the device of the present invention, in the case of movable support, the necessary gap can be formed between the conductor side surface and the side metal fitting without the need for special labor or jigs. becomes easier.
