Fig. 2 is the utility model structure schematic side view.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
General vacuum switch includes several part-structures such as vacuum interrupter, contact spring, galvanic circle, insulator, operating mechanism, support.The multi-break that the utility model proposes serial connection vacuum switch with respect to the main distinction of single break vacuum switch is exactly, and it is that the vacuum switch of a plurality of single breaks is together in series, and guarantees synchronous on the actuating mode and connect, and other structures are substantially similar.
As shown in Figure 1, the utility model comprises an insulating support 1, is separately installed with into and out of line copper bar 2,3 at the upper/lower terminal of support 1.Section in support 1 is tandem and is placed with a plurality of vacuum interrupters 4.There is quiet conducting end 5 on the top of each vacuum interrupter 4, there is moved end conducting rod 6 bottom, between every adjacent two-stage vacuum arc control device head and the tail, be between the quiet conducting end 5 of next stage and the upper level moved end conducting rod 6, all 7 carry out electricity and link to each other by being flexible coupling, concrete mode is: all be connected with on each moved end conducting rod 6 and be flexible coupling 7,7 the other end of being flexible coupling is connected on the horizontal conductive plate 8 that is embedded with in the middle of the support, the quiet conducting end 5 of next stage vacuum interrupter 4 is close to below the conductive plate, and closely connects with conductive lever is firm.Like this, the quiet conducting end 5 of top vacuum interrupter 4 links to each other with inlet wire copper bar 2, and the moved end conducting rod 5 of the vacuum interrupter 4 of lowermost end 7 links to each other with outlet copper bar 3 by being flexible coupling, and realizes conduction.The galvanic circle of switch is: the inlet wire copper bar-quiet conducting end-fixed contact of the elementary vacuum interrupter-moving contact-moved end conducting rod-be flexible coupling-quiet conducting end of secondary vacuum interrupter ...-final stage movable end of vacuum arc extinguishing chamber conducting rod-be flexible coupling-outlet copper bar.
In each moved end conducting rod 6 bottom, all connect an operations linkage plate 9, the end of each operations linkage plate 9 is together in series by cross-under one or a few insulated tension pole 10 on it, realizes mechanical connection.As long as there is a moved end conducting rod 6 to move, other moved end conducting rod 6 also will followed together motion.
