Description
Technical field
The utility model relates to the improvement to outdoor vacuum circuit breaker mechanical property adjusting device.
Background technology
Current outdoor vacuum circuit breaker mechanical property adjusting device comprises wiring pile, lower wiring pile, insulation column and mechanism case; Insulation is provided with vacuum tube in column, inside has moving contact, fixed contact and for grant spring and the insulated tension pole of pressure to moving contact; Mechanism case is stretched in the lower end of insulated tension pole; In mechanism case, be provided with the flat axle of operating mechanism, connecting rod and driving, drive flat axle to be connected by hinge pin with the lower end of connecting rod, connecting rod is connected with the lower end of insulated tension pole by mechanical property adjusting device again.As shown in Figure 6,7.In the time that needs are adjusted mechanical parameter, generally operate according to following steps:
1), assemble after insulation column 2, rule of thumb adjusting respectively degree of depth 1A, 1B, the 1C(that three phase connection 60 screws in insulated tension pole 22 is that three-phase has just closed size), and with specific purpose tool by fastening screw nut 7 tight, then by mechanism, drive flat axle 42, tripping spring and other Assembly of the parts to become complete machine (not back cover plate).
2), console switch separating brake, mechanism drives and drives the transverse movement to the right of flat axle 42, by connecting rod 41, insulated tension pole 22 is moved downward, moving contact 23 in vacuum tube 25 moves downward, make 23,24 of dynamic and static contacts pull open certain gap (open apart from), with distance 2A, 2B, 2C(that slide calliper rule are measured respectively between three phase connection 60 tops (open position) and housing bottom end face (measuring basis) be three-phase separating brake size);
3), console switch closes a floodgate, mechanism drives and drives flat axle 42 by open position transverse movement left, by connecting rod, insulated tension pole is moved upward, vacuum tube moving contact moves upward, and makes dynamic/static contact contact, and compression contacts spring, produces touch pressure.With distance 3A, 3B, 3C that slide calliper rule are measured respectively between three phase connection top (closing position) and housing bottom end face (measuring basis) be three-phase combined floodgate size);
4), press the column corresponding three-phase mechanical parameter of calculating respectively.Homophase combined floodgate size-separating brake size draws this phase total kilometres, homophase combined floodgate size-just closed size to draw this phase excess of stroke, and homophase separating brake size-just closed size show that this opens distance mutually.
5) data that, calculate and canonical parameter contrast each phase parameter whether within critical field.If any arbitrary column parameter, not within critical field, the tripping spring that all will get loose, dismounting drive connecting plate and axle on flat axle and joint, as want the column parameter of adjusting mechanism one side, also will remove mechanism.Then the joint of adjusting the defective column of parameter screws in the degree of depth (just co-bit is put) in pull bar.After adjustment, measure, assemble by said process, whether calculating parameter is up to standard.Still not up to standard, need repeatedly disassemble readjustment, until up to standard.
6), initial adjustment qualified after, carry out mechanical running-in test (every must be done), mechanical Break-in time is 200-300 time by the technical standard of dispatching from the factory.
7) same method is measured separating brake size, combined floodgate size again, calculates the mechanical parameter (generally, parameter all changes) after break-in, now, as not up to standard in arbitrary mutually arbitrary parameter, still will repeatedly disassemble readjustment by step 4, until up to standard.
The process of debugging by above-mentioned mechanical parameter can find out, multiple parts need to be repeatedly disassembled in adjustment, and adjust least unit be half ridge apart from (being 0.6mm), discontinuous.In a word, adjust very cumbersomely, adjust precision inaccurate, adjustment difficulty is very large, causes efficiency of assembling low.
