Description

[Detailed description of the invention] The present invention is a transformer box C and below for electric power company transactions in Yanni vehicle type high voltage power receiving equipment (hereinafter referred to as child vehicle).
(referred to as CT)).

Generally, the installation of PCT is carried out by the electric power company after installation of the cubicle, but since the space for installing PCT inside the cubicle is relatively small and the PCT is heavy (80 to 120 mm), the installation is difficult. construction was difficult.

The structure of the conventional PCT installation is as shown in Figure 5, where there is a PCT space 2' inside the knee bicycle box 1', and the pillow material 3' is fixed to the box 1', and is also used for lifting the PCT. A chain block hook 4' is provided.

However, as for the PCT installation work space, the cubicle component equipment such as air load switch 5', transformer 6', air load switch cover 1', etc. are arranged in the same box, and the upper surface is covered with roof 8. Since it is covered with ', only the open side can be used.

Figure 6 shows the conventional PCT 9' installed, but the bolts of the hanger 10' that secure the pillow material 3' to the PCT 9' are difficult to tighten because there is a roof 8' on the top surface. Furthermore, when hoisting the PCT 9' with a chain block, a certain amount of space is required between the chain block hanging bracket 4' and the pillow material 3' for mounting the PCT. There was a drawback that the height dimension became large.

Furthermore, when lifting the PCT 9' manually without using a chain hoist, there is only one open surface for installation work, which makes the work extremely difficult.

The present invention improves these drawbacks and makes the work easier. As shown in FIG. The open roof 2 is equipped with a rope guide 4 and a chain block hook 5, which are made up of letter-shaped metal fittings, and a support 6 is installed on the open roof 2.
It has a structure that can be fixed with.

In addition, for PCT installation, the pillow material T is equipped with a rope guide 8 consisting of a pipe and a U-shaped metal fitting on its upper surface as shown in Fig. 2, and is not fixed inside the cubicle box.
It can be fixed to the PCT 9 using a hanger 10 on the floor in advance.

Therefore, when lifting the PCT9 after bringing it into the drying vehicle, fix one end of the rope 11 to the rope hook 12 inside the vehicle, and then attach the PCT fixed to the PCT9 from there using the rope of the pillow material I. When the rope 11 is passed through the guide 8 and pulled through the rope guide 4 on the roof 2, the PCT 9 is lifted with a force of about 1/2 of the weight of the PCT.

Furthermore, the lifted PCT 9 and the PCT mounting pillow material 7 are pushed into the back of the knee vehicle to fix the PCT mounting pillow material I inside the cubicle at an angle 13.1.
4 and is fixed with bolts.

At this time, on the front side 13 of the support angles 13 and 14, the PCT mounting pillow material 7 is fastened with bolts, but on the back side 14, as shown in FIG.
6 at intervals according to the width of the pillow material I for PCT installation (
Support) The pillow material 7 for PCT mounting is set using the L carving tool 1.
It will only be posted between 5.16 and 5.16.

Note that FIG. 4 shows another embodiment of the present invention.

As mentioned above, according to the structure of the PCT installation of this invention, the PC
T and PCT installation can be done on the floor by tightening the bolts of the hanger that secures the pillow material, and it can be easily lifted by hand using a rotary bow hook without using a chain block. Block hanging bracket 5
is attached to the inside surface of the roof so that the PCT can be lifted directly above when the roof is open, so even if a chain hoist is used, it is necessary to leave space between the eye bolt and the PCT pillar material. Since the height of the cubicle is eliminated, the height of the cubicle can be reduced.

Furthermore, since the roof is open, there are two open spaces for installation work, which improves work efficiency.

Therefore, in the thousand-knee vehicle type high voltage power receiving equipment with the PCT installation structure of the present invention, the PCT installation work is extremely easy, the height dimension is small, and the practical effect is great.

Claims (1)

[Scope of utility model registration request] The roof of the box body has a hinge-type opening/closing structure, and the inside surface of the roof opening has a rope guide through which the lifting rope is passed when lifting the transformer box with a rope, and a chain block when lifting the transformer box using a chain block. When installing the transformer box inside the cubicle box, the roof is opened and fixed with a support, and the space above the transformer required for lifting the transformer with a rope or chain block is saved. The cubicle-type high-voltage power receiving equipment has a structure in which the transformer box can be mounted, and a rope guide is installed on the pillow material, and an angle is installed inside the box body to fix the pillow material that is lifted using a rope etc. .
