no. 1 Embodiment

[0059] First refer to Figure 7 and Figure 8 The first embodiment will be described. Figure 7 is the plan view of this embodiment, Figure 8 for Figure 7 sectional diagram of the circuit. right with figure 1 The same components are given the same symbols.

[0060] Such as Figure 7 As shown, circuit I is equipped with three circuit breakers CB1, CB2, and CB3 electrically connected in series on the same axis. Such as Figure 8 As shown, disconnectors DS11, DS12, disconnectors DS21, DS22, and disconnectors DS31, DS32 are respectively provided on both sides of circuit breakers CB1, CB2, CB3 through converters CT1, CT2. The isolating switch DS11 is connected to the main bus BUS1 through the connecting bus 12, the isolating switch DS12 is connected to the isolating switch DS21 through the connecting bus 13, the isolating switch DS32 is connected to the main bus BUS2 through the connecting bus 25, and the isolating switch DS22 is connected through the connecting bus 23 O...

no. 2 Embodiment

[0068] Next, a second embodiment will be described with reference to FIG. 9 . The basic constitution of this embodiment and Figure 7 and Figure 8 same as that shown in the first embodiment, Figure 9 is Figure 8 Side view from the Y direction.

[0069] As shown in FIG. 9 , the main busbars BUS1 and BUS2 are opposite to each other and arranged in a triangle in the up and down direction. The heights of the main bus bars BUS1 and BUS2 are substantially the same as the height H of the tops of the circuit breakers CB1a to CB1c of each phase. In addition, the dimension of the distance L2 from the center of the circuit breakers CB1a to CB1c to the main bus BUS2 is only wider than the distance L1 to the main bus BUS1 by the width that a person can pass through. On the side of the main bus BUS2, the front of the circuit breaker operating mechanism (not shown in the figure) and the operation box 110 end of the isolating switch are uniformly arranged.

[0070] The effect and effect ...

no. 3 Embodiment

[0074] Refer below Figure 10 The third embodiment will be described. The basic constitution of this embodiment and Figure 7 and Figure 8 same as that shown in the first embodiment, Figure 10 is true Figure 7 Part X of the magnified plan view of the isolating switch.

[0075] Such as Figure 10 As shown, the first phase DS31a, the second phase DS31b, and the third phase DS31c of the isolating switch are arranged adjacent to each other, and the three phases are connected through a mechanical linkage mechanism 311 in order to switch with one operating device. Similarly, the 1st phase DS32a, the 2nd phase DS32b, and the 3rd phase DS32c of the isolating switches arranged adjacently are connected by the mechanical link mechanism 321 so that they can be opened and closed by one operating device.

[0076] According to the present embodiment described above, the same effects as those of the first embodiment can be obtained, and since the three-phase isolating switch can be o...

Abstract

PURPOSE: A gas valving system is provided to make a variable structure of valving system with no change of the base unit structure. CONSTITUTION: In the gas valving system, at the both side of box of the first, second and third cut off (CB1¯CB3) lie six shutters, each cut off is linearly connected by way of shutter and connection line(12,13). One side of each cut off is connected to the main line(BUS1,BUS2), separated line(14,24) come from the boxes between first and second cut off and between second and third cut off. Bushing of the boxes connected with the front of the separated lines so as to make a unit. The first, second and third cut off of the box are arrayed so that the linking line for the first, second and third actually forms a straight line is between and parallel to the axial line of the main line and the line linking the center of the bushing of each box.

Description

technical field [0001] The present invention relates to a gas insulated switchgear equipped with a high-voltage charging part in a container filled with insulating gas, in particular to a gas insulated switchgear formed by connecting three circuit breakers to a main bus. Background technique [0002] Generally speaking, gas insulated switchgear is composed of a metal container with earth potential filled with SF6 gas, etc., and high-voltage charging components such as circuit breakers, disconnectors, and bus bars are installed inside. For this reason, gas insulated switchgears have been used in various places in recent years because of their high safety and reliability and the ability to significantly reduce the installation area. [0003] However, in critical systems, the figure 1 The 3 / 2CB switching device shown in the circuit diagram. In the configuration of one circuit (circuit I) of this switchgear, three circuit breakers CB1 , CB2 , and CB3 are electrically connected...
