Therefore, it is a good idea to effectively utilize the width of the detention tower, which is determined by the air insulation distance, to improve the functionality of the gas-insulated switchgear. For example, in the case of this type of switchgear, a gas insulated switchgear is designed to have a space for inspecting the circuit breaker, and a space for pulling out the instrument current transformer (hereinafter referred to as MOF) for inspection. It is desirable to configure

置とすることができる。 The bushing 1 connected to the overhead lines of two circuits U 1 , V 1 , W 1 and U 2 , V 2 , W 2 is provided for three phases and is attached to the container of the disconnector 2, as shown in Fig. 3. It is supported by struts 10. This disconnector 2 has vertical disconnectors 3 arranged opposite each other in a straight line.
connected to the upper terminal of the The lower terminals of the shield disconnector 3 are connected via the disconnector 4 by a gas-insulated switchgear side communication bus bar 5. In the preferred embodiment, a direct connection can be made between the lower terminals of the disconnector 3, but a bend may be provided for the disconnector 4. In any case, the configuration consisting of at least one side disconnector 3 and the gas-insulated switchgear side communication bus bar 5 is configured to be approximately parallel to the detention tower 11. Connected between gas-insulated switchgear side and transformer side communication busbars 5 and 7
The MOF 6 can be inspected by pulling it out parallel to the detention tower 11 and towards one of the arrows and toward the disconnector as shown in FIG. Of course, the space for pulling out the MOF can be shared as the inspection space for the shield disconnector 3, so a gas insulated switchgear without wasted space can be achieved.
