Ask for an interview Fig. 3 and Fig. 4, switch gearing device 21 comprises case 2110, tripping mechanism 2116, electromagnet 2106 and baffle plate 2117, in case 2110 and the top that is positioned at case 2110 be provided with add-on module 2105, lid 2104 and binding post 2103, middle part is provided with lid 2102, knob 2101, retainer 2107, damping spring 2108 and elastic component 2109 and locking part 2118, and bottom is provided with protecting cover 2115, guide rod 2111, wire 2112, auxiliary contact 2113 and binding post 2114.
After aforementioned tripping mechanism 2116 is installed along the X being illustrated by Fig. 3 to the bearing of trend that is also the first major loop binding post 221 being electrically connected with contact system 22 shown in Fig. 2 or the second major loop binding post 222 along the Width of control and protective switching device side by side with electromagnet 2106, be installed to together again in case 2110, between tripping mechanism 2116 and electromagnet 2106, locking part 2118 is installed, locking part 2118 is located at by the borehole jack on it on axle of electromagnet 2106 coil racks, moving iron core by electromagnet 2106 is driven, aforementioned shock-absorbing spring 2108 one end are arranged on the boss 21081 of case 2110 bottoms, the other end is resisted against electromagnet 2106 belows.Card base by electromagnet 2106 both sides snaps fit onto them in the hole clipping of case 2110 both sides together, and electromagnet 2106 and case 2110 is located with retainer 2107 simultaneously.
Ask for an interview Fig. 5 to Fig. 7, aforementioned tripping mechanism 2116 comprises an actuator 21161, drives baffle plate 2117 by actuator 21161; Electromagnet 2106 includes bull stick 21061, drives baffle plate 2117 by this bull stick 21061.Baffle plate 2117 shows by the axle 211711(Fig. 4 at two ends) hole 21101(Fig. 2 of offering with case 2110 both sides shows) match and hub setting on case 2110, and between baffle plate 2117 and case 2110, being provided with elastic component 2109(Fig. 3 shows), play and make baffle plate 2117 reply the effect of action.
Binding post 2114, auxiliary contact 2113 and the guide rod 2111 of Fig. 3 signal form an auxiliary signal output unit, wherein, one end of guide rod 2111 is driven by the moving iron core of electromagnet 2106, the other end is provided with moving contact, moving contact mates action mutually with the fixed contact on auxiliary contact 2113, binding post 2114 is plugged on auxiliary contact 2113, thus the on/off switch signal of output major loop.Protecting cover 2115 is connected in case 2110, by it, guide rod 2111 is played to position-limiting action.Aforementioned wire 2112 is also arranged in case 2110, and the support of auxiliary contact 2113 is passed in its one end, and is connected with binding post 2114, and the other end is connected with control module 1 after covering 2115, and it is mainly that external power source is imported in control module 1.
Add-on module 2105 and binding post 2103 another auxiliary signal output units of composition, it is activated by tripping mechanism 2116, thus the status signal of output switch (such as dropout, ready, disconnection).Add-on module 2105 is in place along case 2110 inner side gathering sills, and carries out spacing by covering 2104 to it.Lid 2104 is fixed by the form of clamping with case 2110.Binding post 2103 is plugged in the respective socket of add-on module 2105 by the via hole covering on 2104.
Lid 2102 is connected on the card base of case 2110 both sides and the card base of electromagnet 2106 coil racks by hole clipping, and knob 2101 is set on the axle 21163 of tripping mechanism through the via hole of lid 2102, thereby can manual operation tripping mechanism.
Emphasis is shown in Fig. 4, Fig. 5, under normal circumstances, by electromagnet 2106, the on/off switch of control and protective switching device major loop is controlled, and at this moment, electromagnet 2106, with baffle plate 2117, drive connection occurs.When separating brake, the moving iron core of electromagnet 2106 promotes to show by axle 210612(Fig. 7) be hubbed on the bull stick 21061 on electromagnet 2106 coil racks, bull stick 21061 promotes the pad 21172 on baffle plate 2117 by two boss 210611 on himself, thereby drive baffle plate 2117 to rotate, the contact that baffle plate 2117 promotes on contact system 22 by three boss 211713 on himself supports 2201(Fig. 5 and Fig. 6 to show), thus major loop is disconnected; When combined floodgate, course of action is contrary with above-mentioned separating brake process.Bull stick 21061 more than at least two, just can make their shape control obtain better with the contact point of baffle plate 2117.
As Fig. 4 and Fig. 6, under abnormal condition (as short circuit), control the separating brake of control and protective switching device major loop by tripping mechanism 2116, at this moment, there is drive connection with baffle plate 2117 in tripping mechanism 2116.Tripping mechanism 2116 obtains trip signal and makes actuator 21161 releases later, under the spring-force driven dual of actuator 21161 in tripping mechanism 2116, rotate around axle 21162, axle 211611 on actuator 21161 promotes the face 211712 on baffle plate 2117, thereby drive baffle plate 2117 to rotate, the contact that baffle plate 2117 promotes on contact system 22 by three boss 211713 on himself supports 2201, thereby major loop is disconnected.
The centre of gyration of actuator 21161 is formed by axle 21162; the centre of gyration of baffle plate 2117 is formed by axle 211711; the centre of gyration of bull stick 21061 is by axle 210612; actuator 21161 is face 211712 to the active position of baffle plate 2117; axle 21162, axle 211711, axle 210612 and face 211712 set gradually at the length direction of control and protective switching device (Y-direction shown in Fig. 5, i.e. the first major loop binding post 221 shown in Fig. 2 and both arranged direction of the second major loop binding post 222).
See Fig. 8 and in conjunction with Fig. 5 and Fig. 6, because the centre of gyration of baffle plate 2117 is below the centre of gyration of actuator 21161 and near the centre of gyration of bull stick 21061, baffle plate 2117 is shortened as much as possible at length direction, thereby guaranteed that the deformation of baffle plate 2117 own is less.
The utility model is by arranging the relative position of the centre of gyration of baffle plate 2117, actuator 21161 and bull stick 21061, the centre of gyration of baffle plate 2117 is formed by axle 211711, the centre of gyration of actuator 21161 is formed by axle 21162, and the centre of gyration of bull stick 21061 is formed by axle 210612.The length direction that the centre of gyration of the centre of gyration of actuator 21161, the centre of gyration of baffle plate 2117, bull stick 21061 and described actuator 21161 are all following control and protective switching device successively to the active position of described baffle plate 2117 is arranged; due to the reasonable Arrangement of aforesaid way; the centre of gyration that makes baffle plate 2117 to actuator 21161 to the Distance Shortened between the active position of baffle plate 2117; make baffle plate short as much as possible at length direction, thereby it is less to have guaranteed that baffle plate itself is activated under the effect of part 21161 and bull stick 21061 deformation.
