コスト高になるという問題があった。However, in the conventional switchgear as described above, the fixed electrode 109 and the movable electrode 110 in the vacuum arc extinguishing chamber 106 perform only the operation of opening and closing the main circuit, and the first switchgear. Reference numeral 103 denotes a disconnecting switch for disconnection from other circuits and a grounding switch for grounding the movable electrode 110 in the vacuum arc extinguishing chamber 106 under disconnection. Numerals 104 and 105 function as grounding switches for grounding the corresponding load-side conductors 113. Two switches (first switches) are provided between the bus-side branch conductor 107 and the load-side conductor 113. Switch 1
03 and the second switch 104 or the third switch 105)
Are arranged in series, miniaturization of the container 100 is restricted in order to secure these arrangement spaces, and
There was a problem that the cost was high.

問題があった。Further, an insulating gas is sealed in the inside of the container 1.
Since the switches 103, 104, and 105 are disposed in the switch 00, the switches 103, 104, and 105 are sealed between the movable electrode and the fixed electrode between three phases, between the ground, and at the disconnection position. It is necessary to secure an insulation distance according to the type of gas, and the switches 103, 104, 10
5 becomes larger and each of the switches 103, 104, 1
In order to keep a sufficient interval between the containers 05, there is a problem that the arrangement efficiency in the container 100 is low, and the miniaturization of the container 100 is limited.

問題があった。Further, since the vacuum arc extinguishing chamber 106 is provided for each single phase in the three-phase circuit shown in FIG. 8, the size of the container 100 is reduced in order to secure an arrangement position of the vacuum arc extinguishing chamber 106. However, there is a problem that the cost is limited and the product cost is increased.

製品コストの上昇を招くという問題があった。Further, when an arc short circuit occurs in the container 100, a kind of explosion phenomenon in which the insulating gas sealed in the container 100 becomes high temperature and high pressure within a short time due to the arc energy is caused. Therefore, the container 100 needs to be provided with an open portion for high-pressure release, and is required to have strength to withstand a high-pressure state until the release of pressure, and the structure of the container 100 becomes complicated,
There has been a problem that the product cost is increased.
