Abstract
The utility model relates to an electric closing device. The mechanical shifting mechanism of the utility model mainly comprises a motor, a reducer, a connecting rod and a handle, etc. A projecting shaft of the motor which is deceleration is provided with a runner, the spindle side of the runner is provided with a pivot, the two ends of the connecting rod are connected with the pivot and the handle respectively. The device can be used in low pressure electric switch such as the air switch, the residual current circuit breaker and so on, and can separate brake, reset and close automatically. The utility model has the advantages of selecting the motor of ac or dc, only needing unidirectional rotation, saving the cost of half electronic components, etc, which is a novel electric closing device with simple structure.
Description
The invention relates to the electric switch in a kind of low voltage electric network distribution system, is the automatic closing device with residual current circuit breaker, the supporting application of air switch.
CN90218794.5 discloses two kinds of mechanical structures of " electric operation device for auto-switch ", wherein a kind of " built-in " be can just reverse the deceleration synchronization driven by motor with the single-phase permanent pawl utmost point, the motor rotation drives connecting lever, pulling connecting rod and handle bracket seesaw handle and reach branch, combined floodgate purpose.This is a good scenario, and what slightly sense was not enough is the complexity of the design of positive and negative motor than unidirectional rotation, and the cost of electronic component also exceeds one times, needs for " built-in body ", connecting rod also need spur support, and support is driving handle again, and the application of power is very unreasonable.
The task of the invention is with alternating current or direct current machine, only needs folk prescription to rotation, directly affects the handle top to close a floodgate and separating brake, and it is reasonable that the application of power more becomes.
The design of the invention is that whole device is made up of with the mechanical handling two large divisions of mechanism electric control circuit, the critical piece of mechanical handling mechanism has motor, decelerator, connecting rod and handle etc., to exchange or direct current machine after slowing down, on its external part runner is installed, runner main shaft side is other fulcrum, and the connecting rod two ends connect fulcrum and handle respectively.
Consider that from the cost-saving motor wherein is to select the small-power alternating current machine for well.
Fig. 1 is the structural representation of present design.
Fig. 2 is electrically connected block diagram for this programme.
Fig. 3 and Fig. 4 are the electric control circuit figure of this programme.
Further illustrate the embodiment of the invention with reference to accompanying drawing: behind decelerator 2, runner 3 is installed on the projecting shaft as the motor 1 of Fig. 1, the main shaft side of runner 3 is other fulcrum 4, and connecting rod 5 two ends connect fulcrum 4 and handle 6 respectively.This runner 3 can be that just circle is taken turns, and also can be eccentric wheel.This electric switch-on device is installed in the outside of switch housing, and connecting rod 5 directly affects the top of switch knob 6, and it is reasonable that the application of power is tending towards.As be applied in the integral type residual current circuit breaker, then this electric switch-on device also has an enclosing cover to be covered with outward, covers and is covered with control panel, and relevant hole is arranged.
Fig. 2 is electrically connected in the block diagram, electric control circuit B is behind the reclosing command of receiving signal input part XH input, motor 1 turns clockwise, driving runner 3 rotates, the male contact handle 6 of connecting rod 5 pulling circuit breaker A carries out homing action to terminal, this moment, runner 3 changeed 180 °, runner continues clockwise commentaries on classics again, when surpassing 180 °, just begins feed motion, connecting rod 5 promotes the male contact handle 6 of circuit breaker A (or air switch) to reach, until terminal point, the travel switch of this moment is touched, and B output is closed a floodgate and finished signal, motor, runner 3 stop the rotation, and combined floodgate is finished.Whole separating brake, reset, feed motion, 360 ° of runner 3 rotations.Repeat said process later on again, so do not need motor positive and inverse.
Fig. 3 and Fig. 4 are respectively the electric control circuit figure of direct current machine, alternating current machine, and the K among the figure represents travel switch.
This programme has alternating current-direct current two machines compared to existing technology can be chosen wantonly, only needs single direction rotation, Save half electronic component, reduce cost, power utilize the advantages such as more rational.
Claims (2)
