are packaged separately. The same applies to the other blocks (b, c, d) and voltage transformers (62, 63, 64). The above blocks (a, b, c) centering around the circuit breaker (4, 7)
, d) are arranged in the same manner as in the prior art, so explanations regarding the division will be omitted. Therefore, when comparing the division in the height direction with respect to FIG. 3 and FIG. Since it is only necessary to divide it into four parts by cutting it off, the reassembly time is shortened not only when it is divided at the factory, but also when it is installed on-site, thereby shortening the installation period. In addition, having fewer parts to separate reduces the possibility of defective connections that occur during separation/reassembly, and improves quality by allowing you to identify areas that should be prioritized for withstanding voltage testing. It can be achieved. Furthermore, in FIG. 3, by storing the operation box (70) for the circuit breaker (3) in the pedestal (71),
The length of the entire unit shown in Figure 1 is x1, the conventional length x2
It is shortened compared to (Fig. 6).

[Effects of the Invention] As described above, according to the present invention, among the circuit breakers of the main circuit composing the unit, the three on the left and right are vertical type, and the central circuit breaker is horizontal type, so that the main bus bar is It is placed in a low position and the height of the unit is reduced. Therefore, most of the parts can be stored within the height limit imposed by the transportation facility, and the number of parts that need to be separated is reduced because it is outside the limit, so gas-insulated opening/closing is possible.
This has the effect of shortening the installation period for A-equipment and improving quality.
