Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, the disclosed composite type vacuum circuit-breaker of the utility model mainly by operating mechanism case 1, major loop packing 2, go up isolating switch 3, go up isolator operation bar 4, down isolating switch 5, insulation support plate 6, isolator operation bar 7, vacuum circuit breaker body 8 are formed down.
As shown in Figure 5, the bearing 2-5 of last isolating switch links to each other with vacuum circuit-breaker upper terminal 2-4, and the bearing 2-2 of following isolating switch links to each other with vacuum circuit-breaker lower terminal 2-6.The quiet end of vacuum interrupter 2-3 links to each other with lower terminal with upper terminal respectively with the moved end.This vacuum circuit-breaker when normal operation, electric current through on separate passs, vacuum circuit-breaker upper terminal, vacuum interrupter, vacuum circuit-breaker lower terminal, time isolating switch conducting.
As shown in Figure 4.This composite type vacuum circuit-breaker is in closure state, the loop conducting.Moving contact of isolating switch links to each other with fixed contact in the middle pressure metal enclosed switchgear on it.The moving contact of following isolating switch links to each other with fixed contact in the middle pressure metal enclosed switchgear, has constituted the major loop in the whole metal enclosed switchgear.
Be illustrated in figure 3 as this composite type vacuum circuit-breaker and be in the state of cut-offfing.When needs maintenance power consumption equipment, with manual or electronic vacuum circuit-breaker is cut-off, the major loop no current passes through.With the isolated operation bar in the operating grip rotating mechanism case, isolated operation bar 7 rotated counterclockwise under isolated operation bar 4 clockwise rotated, drives simultaneously in the drive.The conducting rod of isolating switch moves downward in the drive, and the action bars of isolating switch moves upward at present together.Move to when cut-offfing the position, locked by the locking mechanism in the mechanism case.Circuit forms tangible cut-off point.
