JPS5926737Y2 - Cubicle type high voltage power receiving equipment - Google Patents

Description

[Detailed Description of the Invention] The purpose of the present invention is to reduce the height dimension of a cubicle-type high-voltage power receiving equipment (hereinafter referred to as a cubicle).

Conventionally, the height dimension of a cubicle when equipped with a instrument transformer box (hereinafter referred to as PCT) is as shown in Fig. 3.
The mounting of the TI4 is determined by the position and the lifting work space Ha of the PCTI 4, and the height dimension H of the cubicle.
There were limits to reducing d.

A roof 11 is fixed to a cubicle box body 10 with bolts or the like, and eye bolts 12 are used to hook the PCT lifting equipment attached to the inside of the roof, and pillow materials 13 are used to attach the PCT installed inside the box body. This is because the dimension Ha between the two is required as a lifting work space.

The present invention attempts to secure a PCT lifting work space by opening the roof of the cubicle upward, and an embodiment thereof is shown in FIGS. 1 and 2.

FIG. 1 shows the roof in an open state, with the upper end of the cubicle box body 1 bent inward in an L shape and then bent upward to form an edge structure, and a hinge 3 is fixed to this edge. A roof 2 is attached to the roof 2, which can be opened and closed upward by the hinge 3 as shown by the dashed-dotted arrow.

When the roof 2 is in an open state, the stopper 7 provided on the box line part
It has a structure in which it is fixed by a pipe-shaped support 4 that is fastened with bolts or the like to a fastener 6 provided inside the roof board, and the PCT installed inside the cubicle box body is fixed to the pillow material 8. A working space dimension Ha for lifting the PCT 9 between the eye bolt 5 attached to the inner side of the roof plate is secured.

Figure 2 shows the roof closed after the PCT lifting work is completed, but when installing the PCT, the space dimension Hb between the pillow material 8 and the eye bolt 5 attached to the inside of the roof plate becomes extremely small, so the cubicle The height He of the box 1 can also be reduced.

As described above, in the cubicle having the structure of the present invention, it is possible to reduce the height dimension without being limited by the PCT lifting work space, and therefore, it has practical effects such as downsizing the cubicle and saving materials. is a dog.
