Abstract

(57) [Summary] [Purpose] To eliminate the need for work to attach a drain to the roof plate, and to reduce the risk of personal injury such as falling due to work at height. [Structure] The roof plate 11 attached to the box body 1 with the mounting bolts 13 has one drainer 11b formed at the end of the roof plate main body 11a on the box body 2 side, and the drainer portion 11b is attached to the box body 2 Hand over to the roof plate 12 attached with bolts 14.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roof structure for a switchgear installed outdoors.

[0002]

[Prior art]

 FIG. 3 is an example of a switchgear having a conventional roof structure, and FIG. 4 is a sectional view of the roof structure. Roof plates 3 and 4 are attached to the boxes 1 and 2 with mounting bolts 5 and 6, respectively, and a drainer 7 is attached between the roof plates 3 and 4 with mounting bolts 8.

[0003]

[Problems to be solved by the device]

 The conventional roof structure uses a drainer 7 in addition to the roof plates 3 and 4 in order to prevent rainwater and the like from entering the insides of the boxes 1 and 2. This switchgear is carried into the installation location and installed. If it does, it will be necessary to install the drainer 7 on site. Generally, this work is performed at a high place, and there is a risk of personal injury such as a fall accident in a place where the scaffolding is poor such as a construction site. Therefore, the present invention eliminates the work of attaching a drain to the roof plate.

[0004]

[Means for Solving the Problems]

 In the present invention, the roof plate on one side is integrally formed with a draining part at the end of the roof plate body, and the draining part is provided on the roof plate on the other side.

[0005]

[Action]

 With the above-mentioned configuration, the work of attaching the drain to the roof plate is not required, and the work at high places during the assembling work can be eliminated.

[0006]

【Example】

 FIG. 1 shows an example of a switchgear having a roof structure according to the present invention, and FIG. 2 is a sectional view of the roof structure. The roof plate 11 attached to the box body 1 with the mounting bolts 13 is integrally formed with a drainer 11b at the end of the roof plate body 11a on the side of the box 2 and the drainer 11b is attached to the box 2 with the bolts 14. Hand over to the attached roof plate 12. For this reason, the work of attaching the drainer, which was conventionally performed in the assembly work, is unnecessary, and it is possible to eliminate the work at high places especially at the construction site.

[0007]

[Effect of device]

 According to the present invention, it is possible to minimize work at a high place during assembly work and reduce the risk of falling or the like.
