Or flat arrangement can reduce the relative distance between them for three insulation shells of reception threephase cable.But, pars intermedia
The shape of 52b is divided to be not limited to shown shape.I.e., if it is desired, the cross sectional shape of center section 52b can be bowed shape.
From Fig. 3 and Fig. 5, the part 52a that is arranged at the upper part of the Insulating frame with approximately C-shaped section and
It is arranged at the part 52c at the low portion of the Insulating frame and is respectively arranged with cut out portion 53, movable type conductive component 44
Through the cut out portion.Additionally, in the described embodiment, movable type conductive component 44 is by being arranged in upper part 52a
Cut out portion 53 be connected to main circuit.By causing that the low portion 52c of the Insulating frame 52 with approximately C-shaped section also sets
Be equipped with cut out portion 53, when treatment is assembled and be described below, for by bolt 57 by movable type conductive component 44
When being fixed on the fixed work for installing rib 55, the position of insulating bar 56, bellows 64 and movable type lead 45 can be easily carried out
Put regulation.
It is arranged at the part 52c at the lower end of Insulating frame 52 and is formed with cut out portion 54, the cut out portion is used for solid
Sizing conductive component 48 is passed through.Part 52a, 52c with cut out portion of Insulating frame 52 are entirely formed with reinforcing rib 52d.
From Fig. 5-7, each Insulating frame 52 is formed with installation rib 55, so that the machinery of movable type conductive component 44
It is connected to Insulating frame 52.Additionally, from Fig. 3, Fig. 6 and Fig. 7, each Insulating frame is formed with：End surfaces 61 are installed, with
Just so that fixed conductive component 48 is mechanically connected to Insulating frame 52；And case mounting portion 59, so that Insulating frame
52 are mechanically connected to case flange 31a.By this construction, each Insulating frame 52 is connected integrally at its three parts
Movable type conductive component 44, fixed conductive component 48 and case flange 31a.In order that obtaining movable type conductive component 44 and fixed
Conductive component 48 is all firmly attached to each Insulating frame 52, and conductive component 44 and 48 must be by with rigid electric conductor
Manufacture, in an embodiment of the present invention, conductive component 44 and 48 is manufactured by plate-shaped conductive body.
Be explained below the assembling treatment for vacuum valve 46 being arranged in insulation shell 11 (as seen from Figure 3).First,
Selected one in two Insulating frames 52 is installed from the either side in the left side and right side of vacuum valve 46 with fit system
To preassembled movable type conductive component 44, fixed conductive component 48 and vacuum valve 46, while so that chosen insulation frame
The installation end surfaces 61 of frame 52 are contacted with fixed conductive component 48.Then, it is fixed conductive component 48 is exhausted with what is be selected
The installation end surfaces of edge framework 52 are connected by two bolts 62, and the two bolts are screwed from the outside of Insulating frame 52.
Meanwhile, from Fig. 2 and Fig. 5, chosen Insulating frame 52 and movable type conductive component 44 pass through two bolts
57 connections, the two bolts are fastened along from installation rib 55 to the direction of movable type conductive component 44.In this case, vacuum
One of side surface of valve 46 is kept opening, therefore fastening by bolt 57 is easily carried out.
Similar to above, another (or non-selected) Insulating frame 52 is from another in the left side and right side of vacuum valve 46
Side is installed on above-mentioned two part and vacuum valve, while so that described another Insulating frame 52 connects with fixed conductive component 48
Touch.Then, by fixed conductive component 48 and installation end surfaces 61 by two bolts 62 from described another Insulating frame 52
Outside be attached.By this fixing process, as seen from Figure 3, vacuum valve 46 is by including two insulation of Insulating frame 52
Housing 51 is covered.
From Fig. 3 and Fig. 5, due to being provided with the cut out portion 53 provided by Insulating frame 52, can be by means of bolt
57 realize movable type conductive component 44 by by suitable tools insertion cut out portion 53 and using the instrument fastening bolt 57
With the firm connection installed between rib 55 of another Insulating frame 52.In this case, in Insulating frame 52
Case mounting portion 59 near space do not closed by case flange 31a as shown in Figure 2, therefore the space open.Cause
This, movable type conductive component 44 and installation rib 55 can be carried out by bolt 57 from the side of case mounting portion 59 of Insulating frame 52
Connection.
Once fixed conductive component 44 is completed with the connection for installing rib 55, two case mounting portions 59 of Insulating frame 52
Case flange 31a is fixed on by four bolts 60, as seen from Figure 2.
By carrying out above-mentioned assembling treatment, a fixed conductive component 48 and two installation surfaces of Insulating frame 52 61
Connected by four bolts 62, as seen from Figure 3.Additionally, as seen from Figure 5, a movable type conductive component 44 and two insulation
The installation rib 55 of framework 52 is connected by four bolts 57.Additionally, from Figure 2 it can be seen that case flange 31a and two Insulating frames 52
Case mounting portion 59 is connected by four bolts 60.
As described above, each in Insulating frame is connected integrally to movable type conductive component at its three parts
44th, fixed conductive component 48 and case flange 31a, therefore increased the mechanical strength of Insulating frame 52.
As described above, vacuum circuit breaker of the invention has configuration which so that horizontally disposed vacuum valve 46 is by two
Individual Insulating frame is covered from left and right both direction, and the shape of the two Insulating frames is mutually symmetrical, and with when a unit
The shape provided during two parts is provided；And cause at the upper part and low portion of vacuum valve 46 and
Space is defined between the inner surface of Insulating frame 52 and the outer surface of vacuum valve 46.Therefore, even if being arranged in any thermal source
Below vacuum valve 46 or movable type conductive component 44, fixed conductive component 48, vacuum valve 46 and other associated components are sent out
In the case of the influence of heat, flowing up for the insulating gas inevitably occurred in two Insulating frames 52 causes nature
Convection current, therefore improve cooling performance.
Because each Insulating frame 52 with approximately C-shaped section holds part 52a and end portion 52c thereon respectively
Place has cut out portion 53 and 54, therefore movable type conductive component 44 and fixed conductive component 48 can be connect with most short length
To main circuit, the main circuit is arranged in the upper position and lower position of vacuum valve 46 to line.Additionally, each Insulating frame
52 are provided with：Rib 55 is installed, the installation rib is mechanically connected to movable type conductive component 44；End surfaces 61 are installed, fixed is led
Electric part 48 is fixed on the installation end surfaces；And case mounting portion 59, the case mounting portion is used to cause Insulating frame
52 are mechanically connected to case 31；Also, conductive component and case are connected integrally to Insulating frame, thereby while Insulating frame has cutting
Oral area point, Insulating frame can also keep its mechanical strength.
Additionally, because two Insulating frames 52 are arranged on preassembled with assembling mode from the right side and left side of vacuum valve 46
On movable type conductive component 44, fixed conductive component 48 and vacuum valve 46, therefore easily carry out the installation site of each several part
Regulation, therefore improve assembling capacity.
Additionally, because each Insulating frame 52, part 52a and 52c with cut out portion 53 and 54 entirely set
There is reinforcing rib 52d, therefore further increase the mechanical strength of Insulating frame 52.
