Description
Technical field
The present invention relates to a kind of gas-insulated switchgear device that the high-voltage charging parts are housed in insulation gas filled container, particularly about by on main bus bar, connecting 3 gas-insulated switchgear devices that circuit breaker constituted.
Background technology
In general, gas-insulated switchgear device is by being full of SF6 gas etc. in the canister with ground potential, and the high-voltage charge parts that circuit breaker, isolating switch, bus etc. are equipped with in inside constitute.For this reason, owing to its fail safe, reliability height, erection space can reduce significantly, has all utilized this gas-insulated switchgear device in various places in recent years.
But, in important system, then adopt the switching device of the 3/2CB mode shown in the circuit diagram of Fig. 1.In the formation in 1 loop of this switching device (loop I), between main bus bar BUS1 and BUS2,3 circuit breaker CB1, CB2, CB3 are carried out electricity be connected in series.Both sides at each circuit breaker are connected with isolating switch DS11, DS12 respectively, isolating switch DS21, DS22, isolating switch DS31, DS32.From drawing branch bar 14,24 between isolating switch DS12 and the isolating switch DS21 and between isolating switch DS22 and the isolating switch DS31.And, on the top of each branch bar 14,24 insulating sleeve Bg is installed.The formation of loop II is also identical with loop I among Fig. 1.
Below with reference to the example of Fig. 3 explanation according to the existing gas-insulated switchgear device of sort circuit figure formation.Fig. 3 is a plane graph, and the shape that is separated of often adopting in electric pressure high-grade is represented.
As shown in Figure 3, main bus bar BUS1, BUS2 be configured in parallel substantially, between the two with the perpendicular straight line of the axis direction of main bus bar on configured in series 3 circuit breaker CB1, CB2, CB3.The sectional drawing of loop I as shown in Figure 4 among this Fig. 3.At first, on horizontal circuit breaker CB1, isolating switch DS11, DS12 are installed by current transformer CT1, CT2.In addition, in isolating switch DS11, the DS12 earthed switch not shown in the figures is installed usually.Circuit breaker CB2, CB3 are also identical substantially with circuit breaker CB1, have the formation that isolating switch DS21, DS22 and isolating switch DS31, DS32 are installed.
And isolating switch DS11, DS32 are connected on main bus bar BUS1, the BUS2.Isolating switch DS12, DS31 go up the isolating switch DS21, the DS22 that install through connection bus 13,23 with circuit breaker CB2 and are connected. Draw branch bar 14,24 between the connection bus 13,23, connect insulating sleeve (Block Star シ Application グ) Bg1, Bg2 on its top.
But in the configuration of above-mentioned gas-insulated switchgear device constitutes, when feeder number increases, the size A of line direction shown in Fig. 3 will increase.And, even feeder number is few, also need foursquare very big erection space.When particularly being provided with in building, need be as the gymnasium big space sees it is a problem from the viewpoint of effective utilization in building cost, soil.
Its reason is because original 3/2CB mode is 3 circuit breaker arranged in series, and the size B between bus is inevitable very long.In addition, also be that the size A of line direction also needs very long because guarantee insulating sleeve Bg1～Bg4 in the gas-insulated distance.For example, concerning electric pressure was the gas-insulated switchgear device of 500KV level, the size of B was generally 20～30m, and the C size of insulating sleeve line pitch generally also needs 25～30m.Because the C size is the very big constituent element of A size, even therefore 2～3 loops, the A size will be identical substantially with the B size.As mentioned above, just need near foursquare very big erection space.
When the restriction of such erection space, in elongated space, it is just very difficult for example on the weir of dam dike etc. large-scale gas-insulated switchgear device to be set.If further dwindle the size A of line direction, branch bar 34,44 etc. was positioned at circuit breaker CB1～CB3 when last, can cause overslaugh to slinging of circuit breaker CB1～CB3 when then overhauling, and as mentioned above, because the line pitch C size of sleeve pipe need be by certain size of above-mentioned gas insulation distance decision, so dwindling of A size is limited.
In order to address this problem, once to have designed various configurations and constituted.For example be included in the publication communique of Japan: the spy opens clear 59-106808 number, spy and opens the scheme that proposes in clear 61-92106 number.These motions all are to focus on the dwindling of gas-insulated switchgear device, maintenance property aspect, but when a plurality of insulating sleeve, in order to ensure the gas-insulated distance, branch bar must be added to quite long.That is,, make gas-insulated switchgear device realize dwindling significantly, but but exist the relatively more elongated problem of branch bar of gas insulated bushing by adopting high insulating gas.
In addition, also should dwindle size B between the bus that 3 circuit breakers are connected in series, having proposed is not simply 3 circuit breakers to be carried out linear array, but the configuration of zigzag arrangement constitutes scheme.For example open the configuration formation of institute's motion in clear 61-92106 number above-mentioned spy, circuit breaker CB1, CB2, CB3 with the 1st phase bears neighbors respectively mutually exactly, and with meet at right angles direction configuration of bus, equally the 2nd phase, the 3rd is disposed at the bus direction of principal axis mutually successively, compare with straight line configuration on the whole the B size has been dwindled.But, in general be to carry out mechanical link, switch mutually to 3 mostly in isolating switch, the earthed switch with an operating means, and above-mentioned configuration constitute in because the phase spacing wide apart, mechanical link is very difficult.Therefore, go up the operating means that all needs to be added with costliness mutually, have the problem of economy at each.
In addition, as the example that the circuit beyond shown in Figure 1 constitutes, the switching device of circuit diagram shown in Figure 2 is arranged.This is a kind of stable device that adopts of power flow for making transformer station, is the example of alternately drawing branch.Fig. 5 and shown in Figure 6 for example of the gas-insulated switchgear device that this circuit diagram adopted.Wherein Fig. 5 is a plane graph, and Fig. 6 is the loop sectional drawing of the loop II of presentation graphs 5.Constitute according to such configuration, as ise apparent from FIG. 5, branch bar 34,44 is also longer than branch bar 14,24.In addition, the maximum line width A1 also A size than Fig. 3 is long, needs bigger erection space.
