Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an electrical equipment device in which an electrical equipment is placed on a pedestal and a shielding cover is attached to the electrical equipment.

Figures 1A and B show a conventional electrical equipment device a, in which an electrical equipment c such as a small discharge coil device or a current transformer is placed on a pedestal b made of a frame, and this electrical equipment c is further covered. A shielding cover d is attached as shown. The shielding cover d is actually an electrical equipment c
It is attached with the intention of shielding the upper lead-out conductor e, but because the electrical equipment c is small, the electrical equipment c
Since there is no space for the installation above, it is installed on the pedestal b so as to cover the entire electrical equipment c.
The shielding cover d is provided with a lower edge d' placed on a mounting plate f mounted on a pedestal b, and the lower edge d' is an L metal fitting g fixed to the mounting plate f by welding. It is fixed using bolt h.

With this configuration, if the steel mounting plate f suffers from manufacturing distortion or distortion due to long-term use,
A gap is created between the lower edge d' of the shielding cover d and the surface of the mounting plate f, and in those used externally, rainwater enters through the gap and accumulates in the electrical equipment c part inside the shielding cover d. This was a cause of corrosion.

This idea was devised in view of the above points, and even if a gap were created at the lower edge of the shielding cover for various reasons and rainwater entered through that gap, it would never reach the electrical equipment. , it is an attempt to provide an electrical equipment device that is free from the fear of electrical equipment corrosion.

The configuration is such that the periphery of the mounting plate is located inward from the lower edge of the shielding cover, and a continuous rising wall is provided on the periphery. In an electrical equipment device in which a mounting plate is provided, an electrical equipment is mounted on the mounting plate, and a shielding cover is provided on the stand to cover the electrical equipment, a shielding cover is provided on the periphery of the mounting plate. In addition to providing a continuous rising wall, two side edges of this mounting plate are placed and fixed on the pedestal, and the other two side edges are installed so as to maintain a gap between them and the side edges of the pedestal for shielding. The present invention relates to an electrical device characterized in that the cover is located inward from the lower edge of the cover.

This invention will be explained in detail below using example drawings.
This invention is not limited to the following examples.

FIG. 2 shows the overall configuration of an embodiment of the electrical equipment, FIG. 3 shows its main parts, and FIG. 4 shows its planar configuration.

1 is a stand, 2 is a plate for mounting electrical equipment, 3
is the electrical equipment, and 4 is the shielding cover. Electrical equipment 3
A lead-out conductor 5 is positioned protruding from the upper surface of the shielding cover 4, and an opening 6 for connecting a duct for wiring wiring is provided in the shielding cover 4.

Furthermore, the main parts of this invention are shown in Figures 3 and 4.
This will be explained using figures.

The lower edge 4' of the shielding cover 4 is fixed directly onto the pedestal 1 by means of bolts 8 via an L fitting 7 which is fixed by welding. The mounting plate 2 has a continuous rising wall 9 on its periphery, and as shown in FIG. 4, the mounting plate 2 has two side edges (side edges not shown in FIG. It is fixed in place. The other two side edges are positioned so that their rising walls 9 maintain a gap 10 with the side edge of the pedestal 1, as shown in FIG. In this way, the mounting plate 2
By locating the rising wall 9 inward from the shielding cover 4, even if rainwater enters the shielding cover 4 from the lower edge 4' of the shielding cover 4, the existence of the rising wall 9 prevents it from entering the shielding cover 4. It does not reach onto the mounting plate 2, so of course there is no need to worry about the electrical equipment 3 getting wet. In the area where the gap 10 exists, the rainwater that has entered will fall directly downward, and the presence of the gap 10 is useful for appropriately discharging the moisture that has entered the shielding cover 4 as rainwater to the outside. It is preferable that moisture be discharged from inside the shielding cover 4 because dew condensation inside the shielding cover 4 can be prevented.

The above-mentioned gap 10 can also be provided around the four circumferences of the mounting plate 2. In this case, as shown in FIG. Plate 2 for mounting on
Place and fix the corners of the

Still another embodiment will be described with reference to FIGS. 6 and 7. In the device shown in FIG. 6, a rising wall 9 of the mounting plate 2 is provided high over the entire circumference or at several points thereof, and the lower part of the shielding cover 4 is directly fixed to this high rising wall 9. With this configuration, the L fitting 7 for fixing the shielding cover 4 can be omitted, which is advantageous in terms of both manufacturing and cost.

FIG. 7 also shows a configuration in which the L fitting 7 can be omitted, and in this case, the lower edge 4' of the shielding cover 4 is
A bent portion 12 is provided on the frame 1, and this bent portion 12 is
It is fixed with bolt 13.

Since this device is constructed as described above, even if rainwater were to enter the shielding cover, it would be blocked by the rising wall of the mounting plate for electrical equipment and would flow onto the mounting plate and further. Rainwater never reaches electrical equipment.
