Abstract

To provide transposition plate set capable of smoothly exchanging electric equipment when exchanging the existed equipment into new equipment even an external form becomes compact.SOLUTION: In a transposition plate construction used when exchanging the existing equipment into exchange equipment, a plurality of longitudinal holes having an interval corresponded to a floor fixed hole of exchange equipment is provided on an upper surface of a floor transposition plate formed in an U-shaped. In a lower surface, a plurality of lateral holes corresponded to an angle fixed hole of the existing equipment is provided so as to have the interval smaller than the length of the longitudinal holes on the upper surface. By fastening each of holes with a bolt or the like, the exchanging equipment is moved, and in the exchanging equipment, the connection hole height A from a floor area of the existing equipment is hither the height B+C of the connection hole of the exchange equipment obtained by adding the height C. By adding a position of the transposition plates of the exchange equipment to a vertical panel, the relationship of A<B+C is realized, and the connection of a wire can be achieved. Also, various kinds of the exchange equipment for various kinds of the existing equipment can be corresponded with the same floor transposition plate. Thus, an exchange work becomes easily.SELECTED DRAWING: Figure 6

Description

The present invention relates to a closed switchboard (cubicle) for storing electrical equipment in a box, and relates to improvements in a method for fixing and replacing an electrical equipment to be stored.

A conventional example is shown in FIG. 1. Generally, when the electrical device 13 is installed in a box, the front side of the device is supported by the panel 2 and the rear side is fixed by an angle 19 configured in the horizontal direction. 2 is provided with a front fixing hole 16, overlapped with the surface plate 12, and fastened with a bolt or the like, and on the rear side, the equipment fixing hole 8 is fastened to the angle fixing hole 18, thereby fixing the electric equipment 13 from above. It is comprised by connecting to the electric wire 7 of.

When the electric device 13 is aged, it is necessary to replace the electric device 13 with a new one. However, as shown in FIG. 2B, the replacement electric device 3 is generally more compact than the old electric device 13. Because it has been improved and moved forward by the thickness of the front compatible plate, if it is replaced as it is, it will not reach because the device fixing hole 20 has moved forward from the angle 19 supported on the rear side, and Since the height with respect to the electric wire 7 wired from the upper part also becomes low, it does not reach, there arises a problem that the position of the angle 19 is moved and the electric wire 7 can only be replaced.

The replacement of the electric device fixed by the front panel 2 and the rear angle 19 requires a compatible plate set that enables a smooth replacement of the electric device even if the electric device to be replaced becomes compact.

A U-shaped floor compatible plate 4 is constructed at a position that supports the rear of the replacement electrical device 3, which is compact and complements the rear distance that is less than the thickness of the front compatible plate, and is installed in the height direction at the same time. By lifting the device 3 above the connection hole 11, the vertical and horizontal differences in the position of the connection hole are also corrected, and the electric wire 7 is connected without replacement.

A plurality of vertically long holes 5 corresponding to the floor fixing holes 20 of the replacement electric device 3 are provided on the upper surface of the backward compatible plate 4 after the U-shape, and a horizontally long hole corresponding to the angle fixing hole 18 of the existing electric device 13 is provided on the lower surface. Are provided at a pitch H smaller than the width G of the vertically long holes, so that various exchange electric devices 3 can be fixed to the various existing electric devices 13 by the same floor compatible plate 4.

If the existing electrical device 13 is fixed only on the floor, two sets of rear compatible plates 4 are prepared, and one is used at the front and the other is used at the rear, so that the replacement electrical device 3 can also be fixed. It becomes possible.

Effect of the invention

Since the present invention is configured as described above, the following effects can be obtained.

As for the vertical holes 5 on the upper surface of the rear compatible plate, it becomes possible to correspond to the floor fixing holes of a large number of exchange devices by alternately combining a plurality of vertical holes, so Position adjustment is also possible.

With respect to the horizontally long holes 18 on the lower surface of the floor compatible plate, by providing a plurality of holes with a pitch H shorter than the width dimension G of the vertically elongated holes 5 on the upper surface, the position in the vertical direction can be freely adjusted. It is possible to correspond to the angle fixing hole 18 that has been used.

An embodiment of the invention will be described based on an example with reference to the drawings.

[FIG. 2], (a) shows a state in which the existing device 13 is fixed at an angle with the vertical panel, and (b) is to fix the compact replacement device 3 as it is with a pre-compatible plate. In this case, the thickness of the pre-compatible plate is also present, so that it does not reach the angle 19 in the depth direction and does not reach the electric wire 7 in the height direction.

In FIG. 3, (b) shows a state in which the U-shaped floor-compatible plate 4 of the present plan is arranged on the floor of the exchange device 3, and it becomes lower in the depth direction and in the height direction. This shows a situation where the floor-compatible plate 4 corrects the amount that can be replaced as it is.

[FIG. 4] explains the detailed situation of the floor compatible plate 4, and a plurality of vertically elongated holes 5 having a length G corresponding to the width of the floor fixing hole 20 of the exchange device are provided on the upper surface. A plurality of horizontally long holes 18 corresponding to the angle fixing holes 18 of the existing electric device are provided on the lower surface with a pitch H equal to or less than G, and can correspond to various existing devices 13.

[FIG. 5] (a) divides the floor compatible plate 4 into two parts so that a floor compatible plate with a lower height can be manufactured, and (b) divides the floor compatible plate 4 into three parts. The height is adjustable, and both parts can be efficiently stocked in the component state, which is a diagram for explaining [Claim 2].

[FIG. 6] shows the overall configuration of the present invention, and the exchange device 3 can be fixed to the rear floor by the floor compatible plate 4 and can be connected to the electric wire 7 by being lifted upward. The pre-compatible plate 1 is fixed to the vertical panel 2 at an upper position where the exchange device 3 is raised upward.

INDUSTRIAL APPLICABILITY The present invention relates to a closed switchboard (cubicle) that houses electrical equipment in a box, and can be used for a method for fixing and replacing electrical equipment to be housed.

It is a conventional method of fixing electrical devices to panels This is an explanation of a problem that occurs when replacing a compact replacement electrical device as it is when replacing the electrical device. This is an explanation of the use of the backward compatible plate proposed in this proposal to solve the problem. It is a detailed structure of the floor compatible board of this plan It is a modification of the floor compatible plate structure of the present plan, and is a detailed explanation of [Claim 2]. It is the whole structure at the time of applying the compatible board set of this plan.
