[acting on]

It is divided into input state to illustrate with cut-out action the effect of above such present embodiment.It addition, put into State represents in Fig. 1, Fig. 3 (A) (B), and cut-out action represents in Fig. 2, Fig. 4 (A) (B).

(input state)

First, when compound shutter 1 is in input state, from energising plate 14 import electric current to crown cap 12, drive Dynamic device 38, movable electrode 37, fixed electrode 36, crown cap 13, energising plate 15 flow.Further, electric current from energising plate 15 via Insulated electric conductor 6, passes sequentially through energising plate 24, crown cap 22, driving means 57, movable electrode 56, fixed electrode 55, crown cap 23, derive to energising plate 25.

(cut-out action)

On the other hand, when giving the command signal cutting off electric current from the outside of compound shutter 1, it will connect Movable electrode 37,56 driving force in driving means 38,57.Thus, movable electrode 37,56 simultaneously from fixed electrode 36,55 from Open, begin to switch off electric current.

Specifically, in vacuum shutter 3, the movable electrode 37 of vacuum valve 2 leaves from fixed electrode 38.In this process In, between movable electrode 37 and fixed electrode 38, produce the electric arc being made up of the particle evaporated from electrode and electronics.But, by It is fine vacuum in vacuum valve 2, so the material of arcing spreads and losss with cannot leaving shape.Thereby, it is possible to cut off Electrical current.

On the other hand, in high pressure shutter 5, the movable electrode 56 of contact 4 leaves from fixed electrode 55, and at electrode Between produce electric arc, but by assuring that insulation distance between electrode, electric arc is loss.

In this cutting-off process, produce, in the inner space 69 of high pressure shutter 5, the SF6 gas produced due to electric arc Separation gas.This separation gas has the effect of the surface layer of the Dewar vessel 2a that corrosion is made up of the insulating part of vacuum valve 2. But, owing to Dewar vessel 2a is contained in the pressure vessel 7 of vacuum shutter 3, so not worrying by inner space 69 Produce separates the saprophage that gas causes.

It addition, there is the situation that barotolerance is bad in the corrugated tube 2b that vacuum valve 2 has.In the present embodiment, in making The gas pressure in space, portion 68 be corrugated tube 2b can bear pressure, i.e. inner space 69 gas pressure below and atmospheric pressure Above.Thus, guarantee the insulating strength of the contact 4 of inner space 69, while the corrugated tube 2b of protection inner space 68.

As described above, in the present embodiment, in cutting-off process, vacuum shutter 3 is undertaken in SLF cut-out task Transient recovery voltage drastically, the high transient state that the pressure shutter of height 5 that insulating strength is high is undertaken in BTF cut-out task recovers electricity Pressure.So, it is possible to be easily achieved two cut-out tasks.

[effect]

The effect of the most such present embodiment is as follows.

(1) there is multiple shutter, and there is the operating portion driving respective contact portion, so the load of each operating portion Diminish, it is possible to separate contacts at high speed.That is, owing to there is the operating portion 10 of the contact portion 9 driving vacuum shutter 3, driving height The operating portion 20 of the contact portion 19 of pressure shutter 5, it is possible to make operating portion 10 load respective with operating portion 20 diminish, from And separating of high speed can be carried out.

(2) at least one in multiple shutters is responsible for SLF cut-out task, and at least one is responsible for BTF and cuts off task, so Two tasks can be easily achieved.That is, as a shutter, the vacuum shutter 3 with vacuum valve 2 is used, as one Individual shutter, uses the high pressure shutter 5 with the insulating strength contact 4 bigger than vacuum valve 2.Thus, in cutting-off process, Vacuum shutter 3 can undertake the transient recovery voltage drastically in SLF cut-out task.Additionally, the high height of insulating strength is pressure Shutter 5 can undertake the high transient recovery voltage in BTF cut-out task.

(3) due to driving means and movable electrode isoelectric level, so multiple shutter need not guarantee that driving means is with movable Insulation distance between electrode.Therefore, there is no need to the connecting portion of Ins. ulative material.Thus, the weight reduction of movable part, it is possible to high Speed ground separate contacts.That is, the driving means 38 of the operating portion 10 of vacuum shutter 3 and movable electrode 37 isoelectric level, high resistance to presses off Close driving means 57 and movable electrode 56 isoelectric level of the operating portion 20 of device 5.Thereby, it is possible to shorten driving means 38,57 with can The distance of moving electrode 37,56.

Additionally, due to the connecting portion of Ins. ulative material is low with metal material phase specific rigidity, so at the initial stage of cut-out action Ins. ulative material can produce bigger stretching, extension, produce the operating lag of the movable electrode of the action relative to driving means.? In present embodiment, due to the connecting portion of not this Ins. ulative material, it is possible to prevent relative to driving means 38,57 is dynamic The operating lag of the movable electrode 37,56 made.

In addition, owing to driving means 38 is configured in pressure vessel 7, driving means 57 is configured at pressure vessel 17 In, it is possible to shorten the distance of driving means 38,57 and movable electrode 37,56 further, and the weight of movable part can be reduced Amount.

Additionally, due to the connecting portion of driving means and movable electrode does not runs through pressure vessel, it is possible to prevent by connecting Operating lag that sliding friction between portion and pressure vessel causes, gas leakage, the part that causes owing to being provided with sealing The increase etc. of number.

(4) present embodiment is compared with the shutter of the conventional contact portion with multiple arc blow-out type, it is possible to shorter Time carries out guaranteeing of failure of current and insulation distance, it is possible to shorten break time.That is, connect owing to vacuum valve 2 has The contact of touch, and the weight of movable electrode 37 is the least, so vacuum shutter 3 can carry out time the shortest cut-out and move Make.Additionally, as the gas contact portion of arc blow-out type, high pressure shutter 5 also has special operating portion 20.Thus, as multiple The entirety of mould assembly shutter 1, it is possible to make the load of each operating portion 10,20 reduce, separate contacts 4 at high speed.And, work as height In the case of pressure shutter 5 does not have arc blow-out cylinder, nozzle on movable electrode 56, compared with the contact of arc blow-out type, behaviour Make the movable part weight reduction being driven in portion 57.Thus, the operating portion 57 of high pressure shutter 5 can make movable electrode 56 Drive more at high speed, it is possible to shorten significantly in order to ensure the time required for insulation distance.

(5) because being formed as separating contact portion in the shutter that each is different, and each contact portion of receiving is made The structure of space independence, it is possible to making each space is different pressure.More specifically, the gas of inner space 68 is made Pressure is more than below the gas pressure of inner space 69 and atmospheric pressure.Thereby, it is possible to while guarantee the contact of inner space 69 In insulating strength, protection inner space 68 corrugated tube 2b.Additionally, Dewar vessel 2a is contained in pressure vessel 7.Cause This, in cutting-off process, the separation gas of the SF6 gas produced due to the electric arc that produces in inner space 69 no longer with by very The Dewar vessel 2a that the insulating part of empty valve 2 is constituted directly contacts, it is possible to prevent the saprophage effect caused by this separation gas.
