Normally opened contact constitutes relay auxiliary contact.
Specifically, motor drive mechanism 4 drives disconnecting switch separating brake behaviour when disconnecting switch is under "on" position shown in Fig. 2
It is as follows to make process: when there is electric and breaker to be under gate-dividing state in route, relay 42 is powered, and controller exports separating brake order
Afterwards, the reversion of motor 47 drives transmission device 43 and main shaft 1 is isolated and rotates counterclockwise to the separating brake triggering end pressing of sector gear 431
Separating brake stroke opens the shift fork 44 of extension, the output of separating brake travel switch switching state, and motor 47 stops operating.When disconnecting switch is in figure
Under gate-dividing state shown in 3, motor drive mechanism 4 drive disconnecting switch closing operation process it is as follows: when have in route electricity and breaker
Under gate-dividing state, relay 42 be powered, controller output close a floodgate order after, motor 47 rotate forward drive transmission device 43 and every
Shift fork 44 from the combined floodgate triggering end pressing combined floodgate travel switch that main shaft 1 is clockwise to sector gear 431, combined floodgate stroke are opened
Concern changes state output, and motor 47 stops operating.
When disconnecting switch is in gate-dividing state, if maloperation breaker makes breaker closing, at this point, relay 42 after
Electric appliance normally opened contact ZJ-2 is in an off state, and 47 circuit of motor is not turned on, and is only manually operable circuit-breaker switching on-off, can not
Disconnecting switch is driven to close a floodgate by motor 47.Only in the case where relay 42 is powered, 47 circuit of motor can just be connected, and just may be used
Disconnecting switch divide-shut brake is driven by motor drive mechanism 4.The maloperation motor 47 in the case where breaker is in "on" position is avoided, because of motor
47 biggish rotatory forces damage mechanical chain mechanism.
In addition, for the space for making full use of fixed frame 46, to facilitate motor mechanism to be mounted on disconnecting switch bracket, this reality
Apply the same side that relay 42 and motor 47 in example are each attached to fixed frame 46.It in other embodiments, can be in motor
Two sides parallel connection relay normally closed contact, at this point, relay normally closed contact is disconnected in the case where relay coil is powered, motor is returned
Road is connected, and relay normally closed contact is on state in other cases, and electric motor loop disconnects, and is only manually operable open circuit
Device divide-shut brake, above-mentioned relay normally closed contact constitute relay auxiliary contact.In other embodiments, it can not also be set on fixed frame
Relay is set, motor is only controlled by the control switch of motor itself；Relay may also be arranged on fixed frame away from motor
Side.
For convenience of being fixedly connected for fixed frame 46 and disconnecting switch bracket 2, the fixed frame 46 in the present embodiment, which is equipped with, to hang down
Directly in the connecting rod 41 of fixed frame 46, while internal thread hole is set in connecting rod 41, disconnecting switch bracket 2 is equipped with and interior spiral shell
The corresponding welded nut of pit, the internal thread hole in connecting rod 41 will by fastening screw to timing with corresponding welded nut
Connecting rod 41 is fixed on disconnecting switch bracket 2.In other embodiments, can on fixed frame fixed connecting plate, fixed frame with
Disconnecting switch bracket is fixedly connected by connecting plate；Connecting rod can also be by being welded and fixed with disconnecting switch bracket.It needs to illustrate
, transmission device 43, travel switch 45, relay 42 and motor 47 are arranged on fixed frame 46 in the present embodiment, can be only
After vertical debugging, then with assembling circuit breaker in one, later period installation and debugging are convenient.
