There is a support mechanism etc. that supports this, which makes it difficult to increase the capacity. In other words, gas circuit breakers and vacuum circuit breakers are used to downsize circuit breakers, but in the case of vacuum circuit breakers, for example, the vacuum as an insulating medium acts as a heat insulating layer and cannot dissipate heat by itself. For,
There is a limit to the current that can be applied. To solve this problem, it is generally considered to dissipate heat to the outside via the conductor connected to the contact, but as mentioned above, there is a link mechanism, support mechanism, etc. in the upper part of the circuit breaker. This created an obstacle to heat dissipation, and as a result, it was difficult to increase the capacity.

てガス絶縁開閉装置全体の幅を狭くすることができる。[0011] Furthermore, the heat generated by the circuit breaker 1 in the operating state is as follows:
The gas is transmitted to the conductor existing near the upper terminal and the vertical conductor 11, and since there is a gas space especially in the upper part of the circuit breaker 1, and the link mechanism 33 is provided below the circuit breaker 1, the vertical part 32a It is well dissipated by the convection of the insulating gas inside. Further, the insulating case 12 that supports the circuit breaker 1 while electrically insulating it from the closed container 32 is formed in a shape that communicates the vicinity of the upper terminal of the circuit breaker 1 with the gas space within the vertical portion 32a. For example, if the insulating case 12 is configured such that three phases are integrally formed on the side wall 24 side and a substantially vertical plate-shaped portion is located between the three-phase circuit breakers, the insulation case 12 is configured such that a nearly vertical plate-shaped portion is located between the three-phase circuit breakers. The vicinity of the upper terminal of the vessel 1 is opened to the vertical portion 32a side, thereby contributing to the formation of convection of the insulating gas in the vertical portion 32a. Moreover, the circuit breaker 1 is arranged in a part of the closed container 32 located below the main bus bars 4 and 5, and the connection with the main bus side disconnectors 2 and 3 on the side opposite to the main bus bar is a vertical conductor arranged almost vertically. 11
Since the width of the vertical portion 32a is narrowed, the width of the entire gas insulated switchgear can be narrowed.

する。FIG. 4 is a longitudinal sectional front view of a gas insulated switchgear according to another embodiment of the present invention. In this embodiment, circuit breaker 1
Both the upper terminal and the lower terminal are connected to the vertical conductor 11 and the connecting conductor 16 using the tube type collector 1.
3, and by making the width of the vertical part 32a larger than that shown in FIG. A gas space with fewer components than in the case of FIG. 1 is formed. Therefore, heat generated by the current flowing through the circuit breaker 1 is dissipated more efficiently by convection in the gas space within the vertical portion 32a. Further, this embodiment shows a case in which one cable head 7 per phase can handle the current, and the feedthrough current transformer 6 is provided outside the closed container 32 to surround the cable 37. According to such a configuration, the main busbars 4, 5
can be placed closer to the installation surface than in the embodiment shown in FIG. In the embodiment shown in FIG. 1, the main bus bars 4 and 5 are supported on the installation surface via the closed container 32, but in this embodiment, the width of the closed container 32 is reduced and the support legs 36 are used to support the main bus bars 4 and 5 on the installation surface. is supported on the installation surface. Since the configuration of other parts is the same as that of the embodiment shown in FIG. 1, the same reference numerals are given to the equivalent parts and the description thereof will be omitted.

3 can be easily separated. In addition, since the vertical conductor 11 disposed in the vertical portion 32a is biased toward the side opposite to the side wall 24, a sufficient gas space is obtained above the circuit breaker 1, and a further cooling effect due to convection of the insulating gas can be expected. Can be done.

ービクル側から引出せるようにしている。FIG. 5 is a longitudinal sectional front view showing a gas insulated switchgear according to still another embodiment of the present invention. While the previous embodiment was a double main bus system having two main bus bars 4 and 5, this embodiment is a single bus system using only the main bus 4. The main bus 4 and the main bus side disconnector 3 are separated by an insulating spacer 22
The mover 28 of the main bus side disconnector 3 is connected to the ground terminal 38 at the disconnection position by the operating device 19a or at a further overstroke position. It is constructed so as to be in contact with each other so that it also serves as a grounding switch 9. A connecting conductor 16 similar to that of the previous embodiment is disposed in a sealed container 32 connected to a main bus container 29 via an insulating spacer 22.
A disconnector 39 is constructed in the middle of the line 6. This disconnector 39
The movable member 40 is opened and closed by an operating device 19b disposed in parallel to the operating device 19a in the cubicle 17 shown in FIG. Disconnector 3
It also constitutes a grounding switch for grounding the circuit breaker 1 side of circuit breaker 9. The circuit breaker 1 inside the closed container 32 is connected to the side wall 2 of the closed container 32.
4 via an insulating case 12, and is arranged vertically, with a link mechanism 33 connected to its lower side, and opened and closed by an operating device 18 configured on the back side of the side wall 24. . Therefore, there is no link mechanism on the upper side of the circuit breaker 1, and the circuit breaker 1 faces the upper wall of the closed container 32 with a gas space interposed therebetween. This circuit breaker 1 can be installed at any height, but in this embodiment it is installed at almost the same height as the main bus 4, and its upper and lower terminals are connected by tube-type current collectors 13. As in the previous embodiment, by moving the side wall 24 to the right, electrical contact at the tube type current collector 13 is broken, so that the circuit breaker 1 can be pulled out from the cubicle side.

る。In this embodiment as well, the circuit breaker 1 is opened and closed by the operating device 18 via the link mechanism 33 provided on the lower side, and the upper side is connected to the closed container via the gas space of the vertical portion 32a. 32, the heat generated from the circuit breaker 1 is dissipated by convection using the insulating gas within the vertical portion 32a. In addition, since the upper terminal of the circuit breaker 1 is at almost the same height as the main bus 4 and the main bus-side disconnector, it is possible to connect the upper terminal and the side opposite to the main bus of the main bus-side disconnector 3 with the tulip type collector 13. ,
By moving the side wall 24 in its removal direction, the electrical connection by the tube current collector 13 can be easily separated. However, if the circuit breaker 1 is located below the main bus bar 4, although the above-mentioned effect is lost, the gas space above the circuit breaker 1 can be effectively used for forming convection of the insulating gas, and the vertical By narrowing the width of the portion 32a, the entire insulated switchgear can be reduced in the width direction.

Although the circuit breaker 1 can be pulled out for inspection, etc., the side wall 24 may be integrated with the closed container 32 if a separate method for inspecting the circuit breaker 1 is considered.

This circuit breaker is placed so as to face the upper wall of a sealed container with a vertical section above it, which facilitates the convection of insulating gas in the vertical section, thereby dissipating the heat of the circuit breaker and allowing current to flow. By increasing the current, it is possible to increase the capacity of the gas insulated switchgear.
