2/82 KV class as Conventional Examples 1 to 3 and FIGS.
Shown in First, the configuration diagram of the single-line diagram is shown in FIGS.
Shown in In the figure, ES is a grounding switch, VCB is a vacuum circuit breaker, DS is a disconnector, and MOF is a transformer for an instrument. Each of these devices is a power receiving unit A, a transformer unit B, a MO
Each unit is divided into F units C, and each device is accommodated in the housing for each unit arranged as shown in FIGS.

点数が多くなる。However, as shown in FIGS. 5-7 (b), the power receiving unit A has a connection bus at the bottom, while the transformer unit B has a connection bus at the top. Therefore, not only does the height of the gas insulated switchgear increase, but the gas insulated switchgear is different between the upper and lower parts, so that parts cannot be shared and the number of parts increases.

Not only is the height H of the HD small and workability is poor,
The space for mounting the current transformer CT is reduced. Further, the vacuum circuit breaker VCB and the cable head connection conductor are arranged in parallel, so that the depth dimension S increases.

で説明を省略する。For this reason, the cable head CHD can be arranged at a high position (height H) beside the equipment tank 3. Thereby, the mounting range of the current transformer CT is increased in the vertical direction. As shown in FIG. 4, the vacuum circuit breaker VCB and the inner conductor are not arranged in parallel unlike the conventional one shown in FIG. 8, so that the depth dimension L of the power receiving unit A and the transformer unit B is small. In addition, the depth dimension of the gas insulated switchgear is also small. (B) Embodiment 2 Next, Embodiment 2 of the gas insulated switchgear according to the present invention is shown in FIG.
(A) to (c) are shown. In this embodiment, in addition to the gas insulated switchgear of the first embodiment, a bypass unit P for forming a bypass circuit is provided. Then, along with that, the disconnecting switch DS and the installation switch ES in the MOF unit C.
Is added. The other configuration is the same as that of the first embodiment, and the description is omitted.

An F unit C is provided. Then, along with that, the disconnector DS,
A grounding switch ES is added, and a disconnector DS and an auxiliary unit R having a grounding switch ES are interposed between the power receiving units A and between the transformer units B, and an auxiliary unit Q is provided outside the power receiving unit A. The auxiliary unit S is provided on these units.

低コスト化できる。In each of the power receiving units A and the transformer units B in the first to third embodiments, the bus tank is disposed at the lower part, and the internal configuration is the same. Therefore, if the auxiliary unit P and the like are added to the gas insulated switchgear of the first embodiment, the gas insulated switchgear of the second embodiment can be obtained.
If S is added, the gas-insulated switchgear of the third embodiment is obtained. In other words, by arranging the busbar tank at the lower part, the power receiving unit and the transformer unit can be shared as shown in the first to third embodiments, and the cost of the gas insulated switchgear can be reduced.

According to the gas insulated switchgears according to the first to third aspects, since the bus tank is arranged below the power receiving unit and the transformer unit, the equipment unit is inevitably arranged above and the mounting position of the cable head can be raised. In addition, since the bus bar is not disposed above the unit, the depth of the unit is reduced, and the gas insulated switchgear can be downsized.
