Abstract
An automatic conversion switch electric device comprises a baseboard, a motor, two circuit breakers, an escapement and a controller, wherein the motor is installed on the middle portion of the baseboard surface; the two circuit breakers are arranged on the surface of the baseboard on two sides of the motor; and the controller is used for controlling the operation of the motor, the escapement is composed of a transmission rod and two actuators, the middle portion of the transmission rod is fixed on an output shaft of the motor, the two actuators are hinged at the bottom of the two ends of the transmission rod respectively, and each of the actuator is contacted with a switch handle of each of the circuit breakers. According to the automatic transfer switching equipment, the connection mode of the two actuators with the transmission rod of the escapement is changed from a fixed connection mode into a hinge connection mode, so that direction of motion of the actuators is consistent with that of the switch handle on the circuit breakers, the force of the switch handle is even, the motion of the switch handle is stable, and each contact can move synchronously.
Description
Technical field
The utility model belongs to technical field of electrical equipment, particularly relates to a kind of automatic transfer switching electric appliance.
Background technology
Automatic transfer switching electric appliance is a kind of use low voltage component widely; Mainly be to utilize the controller on it to drive the action that motor-operating mechanism comes control switch;, stand-by power supply commonly used with connection or disjunction; Thereby guarantee the safety of electric power system and the continuity of production, it mainly comprises base plate, motor, two circuit breakers, escapement and controllers; Wherein motor is installed in the middle part, surface of base plate; Two circuit breakers are set in place in the backplate surface of motor both sides; Escapement is made up of drive link and two actuators, and the middle part of drive link is fixed on the output shaft of motor, and two actuators are installed in the bottom, two ends of drive link respectively, and each actuator respectively with a circuit breaker on switch knob contact; Controller then is used to control the running of motor.But; There is following point in the automatic transfer switching electric appliance of this prior art: because two actuators are to be fixedly mounted on the drive link; Therefore when motor rotated, escapement was to clamp the mode translation of switch knob, in this process; The power that actuator is applied on the whole switch knob will be uneven, thereby cause on the circuit breaker action of each contact asynchronous.
Summary of the invention
In order to address the above problem, the purpose of the utility model is to provide a kind of switch knob that makes stressed evenly and the automatic transfer switching electric appliance of stable action.
In order to achieve the above object, the automatic transfer switching electric appliance that provides of the utility model comprises base plate, motor, two circuit breakers, escapement and controllers; Wherein motor is installed in the middle part, surface of base plate; Two circuit breakers are set in place in the backplate surface of motor both sides; Controller is used to control the running of motor; Escapement is made up of drive link and two actuators, and the middle part of drive link is fixed on the output shaft of motor, and two actuators are hinged on the bottom, two ends of drive link respectively, and each actuator respectively with a circuit breaker on switch knob contact.
Described actuator is the U-shaped structure, and it is hinged on the drive link with the mode that Open Side Down, and clasp is in the outside of switch knob.
The automatic transfer switching electric appliance that the utility model provides is to change being connected by fixed form between two actuators of escapement on it and the drive link into articulated manner; The direction of motion that so just can guarantee switch knob on actuator and the circuit breaker is consistent; Make stressed even, the stable action of switch knob, each contact can synchronization action as a result.
Description of drawings
The automatic transfer switching electric appliance structural representation that Fig. 1 provides for the utility model.
Fig. 2 is escapement structural representation on the automatic transfer switching electric appliance shown in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the automatic transfer switching electric appliance that the utility model provides is elaborated.
Like Fig. 1, shown in Figure 2, the automatic transfer switching electric appliance that the utility model provides comprises base plate 1, motor 2, two circuit breakers 3, escapement 4 and not shown controllers; Wherein motor 2 is installed in the middle part, surface of base plate 1; Two circuit breakers 3 are set in place base plate 1 surface in motor 2 both sides; Controller is used to control the running of motor 2; Escapement 4 is made up of drive link 5 and two actuators 6, and the middle part of drive link 5 is fixed on the output shaft of motor 2, and two actuators 6 are hinged on the bottom, two ends of drive link 5 respectively, and each actuator 6 respectively with a circuit breaker 3 on switch knob 7 contact.
Described actuator 6 is the U-shaped structure, and it is hinged on the drive link 5 with the mode that Open Side Down, and clasp is in the outside of switch knob 7.
When carrying out the branch closing operation when motor 2 rotations and to two circuit breakers 3; Coupled drive link 5 also together produces rotation, at this moment, and under the reaction force acts that switch knob 7 applies; The actuator 6 that is installed in drive link 5 two ends will rotate on drive link 5; In this process, the medial surface of actuator 6 contacts with the outer surface of switch knob 7 all the time, therefore can guarantee that actuator 6 is consistent with the direction of motion of switch knob 7; Will make stressed even, the stable action of switch knob 7 like this, each contact can synchronization action as a result.
