Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mobile substation device, and more specifically, to a mobile substation device in which a substation device including a transformer, a breaker, a disconnector, etc. is loaded on a moving vehicle such as a trailer. This relates to substation equipment.

FIG. 1 shows a conventional device of this kind, in which a control panel of a power substation device, a transformer 3. The circuit breaker and the circuit breaker are stacked in tandem, next to each other.

Conventional mobile substation equipment was configured as described above, so as the insulation level increases (]/.

du, d,? The ground insulation distance shown by
If the ground insulation distance and space required for connections are secured and the equipment is simply loaded onto a moving vehicle, the overall length of the mobile substation device and, by extension, the moving vehicle will become longer, and the turning radius of the moving vehicle will become larger. This causes the road to turn (or bend), making transportation extremely time-consuming.Furthermore, when transporting such equipment by ship, transportation costs are often determined based on volume rather than actual weight; The disadvantage was that the longer the total length, the higher the transportation costs, such as extra freight charges being applied to long items.

Furthermore, this type of mobile substation equipment also serves as a replacement for existing substations that become unavailable for some reason, and when used in this role, mobile substation equipment If the full length is too long, the disadvantage is that you will have to secure a large space to store it while it is on standby.

This invention aims to solve these problems.
The disconnector is divided into a movable part side support insulator part and a fixed terminal side support insulator part, and the disconnector and the movable part side support insulator part of the disconnector are integrated on a common frame, and the disconnector is fixed. The terminal side support insulator constitutes two moving parts, and during transportation or storage, the blade of the disconnector can be removed and
The object of the present invention is to provide a mobile substation device whose overall length can be shortened by moving the two movable parts separately to the transformer side so that the distance is the minimum required for transportation or storage. It is.

An embodiment of the present invention will be described below with reference to the drawings. Figure 2 shows a mobile transformer during transportation or storage, with the control panel of the transformer and the transformer 3 loaded in predetermined positions on the loading platform of a moving vehicle 1, and the breaker and disconnector. S moving part side support insulator part! The two movable elements, which are composed of a part configured to be fixed to the common stand 6 and integrated with the fixed terminal side support insulator part 5a of the disconnector S, are transported to the transformer 3 side, respectively. Or, they are biased to the maximum distance necessary for storage, and the blades of the disconnectors S are removed and stacked in tandem.

Figures 3 and 3 each show the form in which it is used as a substation device at the site, and the breaker t and the movable part side support insulator part of the breaker S, tb, are integrated on a common mount B. The configured part and the fixed terminal side supporting insulator part of the disconnector
Move a to the specified operating position, and then press the disconnector! The figure shows an operating state in which the blade SC of the disconnector S is disconnected several times in its normal position.

At this time, the fixed terminal side supporting insulator part 5a to be moved comes off from the loading platform of the moving vehicle/, but this is because it has been attached to the moving vehicle/ by the hinge g in advance and is tightened by the mounting bolts 10, as shown in FIG. Possible means include supporting it with a locked folding support g, or supporting it with a separate pedestal as shown in FIG. In addition, a separate stand/
Needless to say, it would be more convenient to transport the / by loading it onto a mobile substation device.

Further, as a means for moving the equipment, it is possible to easily move the equipment by using moving wheels 7a and 7b, as shown in Figs. Further, as other methods, a hydraulic operating mechanism, a compressed air operating mechanism, an electric operating mechanism, a feed screw operating mechanism, etc. may be used. .

As is clear from the above explanation, according to this invention V,
The breaker and the supporting insulator on the movable part side of the disconnector are configured to be integrated on a common frame, and the supporting insulator on the identification terminal side of the disconnector constitute two *6gJ elements, and these are separated separately. By loading it closer to the transformer so that it is the minimum distance required for transportation or storage, it is possible to shorten the overall length of the mobile substation equipment, and by extension, the overall length of the mobile vehicle during transportation or storage. It becomes easier for a moving vehicle to enter an intersection, etc., and the bending moment of the loaded object against the moving vehicle is small, so the rigidity of the moving vehicle can also be reduced, making the moving vehicle lighter and cheaper. can be realized. Also, regarding the storage location,
A smaller space is required compared to conventional equipment.
