In Figure 1, it is stored in drawer frame 1.
Two shutters 3 are provided to respectively protect the fixed terminal 1a on the power supply side and the fixed terminal 1a on the load side disposed on the drawer frame 1 when the VCB main body 2 is pulled out from the drawer frame 1. There is. That is, the shutter 3 is provided on the drawer frame 1 side and is movably incorporated as a part of the protective structure.

The protective structure includes two shutters 3 whose longitudinal direction of a rectangle is arranged in the Z-axis direction, which is perpendicular to the plane of the paper, and which are arranged at a predetermined interval on a straight line in the Y-axis direction; Above, two rolls 4 are disposed directly below the shutter 3 and facing each other at the ends in the Z-axis direction, and two sets of connecting rods 5 connect the shutters 3 and the rolls 4 at both ends, respectively. It is composed of.

In addition, two sets of couplers 2a fixed to the left side of the VCB body 2 at a predetermined interval in the Y-axis direction and two sets of fixed terminals 1a removably connected to the drawer frame 1 insulate the fixed terminals 1a. It is fixed to the center of the insulating cylinder 1b. Note that the two sets of insulating cylinders 1b are fixedly arranged with an interval of at least the width L of the shutter 3 or more. Furthermore, VCB main body 2
A spacer 2d is provided between the rail plate 2b, which has the shape of an inclined part and a horizontal part and is fixed to the bottom of the VCB main body 2 so as to engage with the roll 4, and the lead-out terminal 2c attached to the coupler 2a. A vacuum switch 2e with a fixedly attached vacuum switch 2e is attached to each.

Thus, when the VCB body 2 is pulled out in the X direction indicated by the arrow, the coupled coupler 2a gradually separates from the fixed terminal 1a, and when the roll 4 comes into contact with the lowest position of the sloped part of the rail plate 2b, the VCB is completely removed. It becomes disconnected. In addition, the shutter 3 does not move on the horizontal part of the rail plate 2b, but when it comes into contact with the sloped part, it gradually starts to descend from the position where it was stationary at the top of the insulating tube 1b and comes into contact with the lowest position of the sloped part. When this happens, the fixed terminal 1a is completely sealed. On the other hand, insert the VCB main body 2 into the drawer frame 1
If the device is stored in a storage space, the effect is opposite to the above-mentioned effect. That is, when the VCB main body 2 begins to be stored in the drawer frame 1 and the roll 4 reaches the highest position on the slope of the rail plate 2b, the shield of the insulating tube 1b is opened,
When the VCB body 2 is housed, the fixed terminal 1a is completely connected to the coupler 2a.

As described above, when the VCB main body 2 is housed in the drawer frame 1, the shutter 3 must always be held at the top of the insulating tube 1b. Therefore, the distance E between the fixed terminals 1a is determined by the width of the shutter 3, which is determined by the size of the insulating tube 1b. This requires extra space to be provided between the insulating tubes 1b. Also, by this
Since the overall length of the vacuum switch 2e is short, a spacer 2d must be inserted when it is installed between the couplers 2a. Here, the height F of the drawer frame 1, that is, the height of the VCB increases, and when operating VCBs stacked in several stages, maintenance inspections, troubleshooting, etc., become extremely dangerous operations. Ta. Furthermore, since the height is several times as high as the floor area occupied by the drawer frame 1, it is extremely dangerous against earthquakes.

The drawer frame 1 is configured with tension springs 9 provided on both sides of the drawer frame 1 to prevent it from opening vertically symmetrically about the guide rod 8. In addition, two sets of couplers 2a provided on the VCB main body 2 at positions facing the two sets of fixed terminals 1a fixed to the drawer frame 1 and a collar portion 6a of the receiving plate 6 included in the protective structure are pressed. A side plate 2f is provided for this purpose. In this embodiment, one end of the tension spring 9 is attached to the drawer frame 1 and the other end is attached to the lower shutter 3, but it may also be attached to the upper shutter 3, and both ends of the tension spring 9 can be attached to the upper and lower shutters, respectively. It may also be attached to the shutter to prevent it from opening.

Next, in FIG. 5, the VCB body 2 is stored in the drawer frame 1 from the disconnected state shown in FIG. 4, and is stored in the direction of arrow X' along the rail 1e in order to connect the coupler 2a to the fixed terminal 1a. start. Then, when the VCB body 2 is retracted to a certain extent, the VCB
The side plate 2f of the main body 2 presses the collar 6a of the receiving plate 6 at the same time. Further, when this VCB main body 2 is stored in the drawer frame 1, the receiving plate 6 slides along the guide rod 8, and the two sets of links 7a, 7b begin to open in a fan shape against the tension spring 9. On the other hand, the shutter 3 which had been shielding the fixed terminal 1a opens vertically symmetrically due to this. That is, along the U-shaped groove 1c, the shutter 3 in the upper part moves upwardly of the insulating cylinder 1b in the upper part, and the shutter 3 in the lower part moves in the downward direction of the insulating cylinder 1a in the lower part. At this time, the tension spring 9 is further stretched by the movement of the shutter 3. Then, when the two sets of links 7a and 7b are almost in a straight line, the storage of the VCB body 2 is stopped by the action of a stopper (not shown), and the shutter 3 completely releases the shield of the fixed terminal 1a. ,
The fixed terminals 1a are connected by a coupler 2a.

As explained above, according to the present invention, a space corresponding to the width of the shutter was previously provided between the insulating cylinders arranged above and below, but by using a protective structure that opens in a fan shape, the space can be reduced. There is no longer a need to provide one. As a result, the height of the VCB has been lowered by the extra space, making it less dangerous and easier to perform maintenance, inspection, and troubleshooting on VCBs stacked in several tiers than with conventional models. Furthermore, stability has been improved in terms of earthquake countermeasures, and there is no longer a need to provide a spacer at the attachment point of the vacuum switch.
