Description of drawings
Fig. 1 is the main TV structure schematic diagram of part-structure of the present invention and annex combined operation mechanism;
Fig. 2 is the plan structure schematic diagram of part-structure of the present invention and annex combined operation mechanism;
Among the figure, 1 electromagnet, 2 links, 3 rocking bars, 4 master connecting-rods, 5 rocking arms, 6 keepers, 7 knobs, 8 fixed heads, 9 fault covers, 10 fault rocking bars, 11 top boards, 12 normally-open normally-close sets of contacts, 13 fault alarm contacts, 14 short-circuit alarming contacts, 15 normally open contacts, 16 fault push rods, 17 fault releases, 18 short-circuit releases.
Embodiment
Further specify the present invention in conjunction with the accompanying drawings and embodiments; as Fig. 1; shown in 2; the present invention is the improvement on existing control and protection switch electrical structure basis; auxiliary accessory combined operation mechanism is set on pedestal; Rocker arm 5 one end in the auxiliary accessory combined operation mechanism connects the link 2 of moving iron core one end of electromagnet 1 in the permanent mechanism driving mechanism; rocking bar 3 one ends in the auxiliary accessory combined operation mechanism touch normally-open normally-close sets of contacts 12; fault rocking bar 10 1 ends in the auxiliary accessory combined operation mechanism touch fault push rod 16; the other end of fault rocking bar 10 touches fault cover 9, the 9 card Alarm contactor actions of fault cover.As shown in Figure 1, auxiliary accessory combined operation mechanism comprises two parts, a part is made up of Rocker arm 5, master connecting-rod 4, rocking bar 3 and normally-open normally-close sets of contacts 12, one end of the hinged Rocker arm 5 of one end of master connecting-rod 4; other end of Rocker arm 5 connects the link 2 of moving iron core one end of electromagnet 1 in the permanent mechanism driving mechanism, and the middle part of Rocker arm 5 and keeper 6 are hinged; The other end of master connecting-rod 4 connects rocking bar 3; As shown in Figure 2, another part is made of fault rocking bar 10, fault push rod 16 and fault cover 9, and fault rocking bar 10 is hinged on the fixed head 8 near center.
Under the normal operating conditions: when knob 7 is in automatic control position, normally open contact 15 closures of control circuit, control circuit passes through electromagnet 1 adhesive controlled, drive link 2 motions, with keeper 6 is central point, and the Rocker arm 5 that connects link 2 rotates around keeper 6, does stroke motion and drive rocking bar 3 master connecting-rod 4 motions that the other end of Rocker arm 5 connects the time, rocking bar 3 is upwards taken exercises, and promotes normally-open normally-close sets of contacts 12 and carries out motion change.Rocking bar 3 is positioned in the accessory case, after the master connecting-rod action, promotes rocking bar 3 actions, thereby makes the action of normally-open normally-close sets of contacts.
Can be divided into two kinds of situations under the fail operation state:
1), generic failure (overload, phase shortage, three-phase imbalance etc.): when generic failure occurs, fault release 17 detects action (improper action) after the fault, promote fault push rod 16, fault push rod 16 makes 10 motions of fault rocking bar, fault rocking bar 10 promotes 9 actions of fault cover, make 13 actions of fault alarm contact send alarm signal, be that generic failure makes operating mechanism effect to fault alarm contact 13 send alarm signal, but the short-circuit release 18 that detects short trouble does not move, short trouble top board 11 not being worked makes the short-circuit alarming contact send signal, can be judged as generic failure in view of the above.
2), short trouble; When short trouble occurs, short-circuit release 18 actions, promote short trouble top board 11, short trouble top board 11 promotes fault rocking bar 10 and carries out the overtravel motion, fault rocking bar 10 promotes fault and overlaps the action of 9 overtravels, short-circuit alarming contact 14 and fault alarm contact 13 are moved simultaneously, send short-circuit alarming signal and failure alarm signal simultaneously.
