Problems solved by technology

[0004] In the automatic opening and closing device disclosed above, although the automatic opening and closing operation of the circuit breaker can be realized, it still has at least the following technical defects: 1. Since the driving gear (bevel gear) on the motor shaft directly acts on the On the driven gear of the action, the power output by the motor is required to be high, and the stopper on the driven gear pushes against the protrusion on the linkage during the rotation process, thereby driving the linkage to rotate to open and close the handle of the circuit breaker The brake action, the force of the transmission movement changes unevenly, resulting in the increase of the transmission friction between the gears, and there is only one set of gears, the transmission ratio is small, and the torque am

Embodiment 1

[0047] Attached below Figure 1-9 The automatic opening and closing control device provided by this embodiment is described in detail:

[0048] An automatic opening and closing control device provided in this embodiment includes a housing 1, a drive motor 5, a control module, and a circuit breaker handle mechanism arranged in the housing 1, and the drive motor 5 and the The gear transmission mechanism of the circuit breaker handle mechanism, the control module controls the rotation shaft 51 of the drive motor to rotate forward or reverse, and drives the gear transmission mechanism and the circuit breaker handle mechanism to perform opening and closing actions, wherein, The gear transmission mechanism includes: a driving gear 2, a transmission gear 3 and a handle gear 4 meshed in sequence, the driving gear 2 is set on the motor shaft 51 in linkage, and the handle gear 3 drives the circuit breaker handle mechanism to operate The transmission gear 3 includes a driving gear 31 me...

Embodiment 2

[0063] The present invention provides a circuit breaker, such as Figure 10-12 As shown, it includes the circuit breaker body 9, the contact structure, the operating mechanism, and the automatic opening and closing control device described in Embodiment 1, wherein A indicates the circuit breaker, and B indicates the opening and closing device; the circuit breaker of this implementation Because the automatic opening and closing control device in Embodiment 1 is provided, it naturally has all the advantages brought by the above-mentioned control device.

[0064] To sum up, the automatic opening and closing operation of the circuit breaker can be realized through the remote control function in the opening and closing control device, that is, when the user owes the fee, the remote control circuit breaker will be opened and locked in an inaccessible state. In the closing state, when there is a user in arrears, the remote control closing is performed, and manual opening and closing ...

Abstract

The invention discloses an automatic opening/closing control device and a circuit breaker. The automatic opening/closing control device comprises a housing, a driving motor arranged in the housing, a control module, a circuit breaker handle mechanism, a gear drive mechanism and a linkage locking piece. The gear drive mechanism is formed by a drive gear, a transmission gear and a handle gear, which are engaged. Through forward rotation or backward rotation of the motor, a driven gear in the transmission gear drives the handle gear to carry out forward or backward transmission, and the handle gear drives the circuit breaker handle to realize opening/closing; after arrearage opening, the linkage locking piece and a locking component keep in a locked state, so that the circuit breaker cannot be closed; and after payment closing, the circuit breaker can be subjected to free opening/closing operation. According to the technical scheme, gear transmission transformation ratio is improved greatly, transmission efficiency is improved, service life of the motor can be prolonged favorably, a transmission mode of mutual pushing is prevented, structure performance is stable, cooperation is reliable, transmission efficiency is high, and use performance of the product is improved.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to an automatic opening and closing control device and a circuit breaker thereof. Background technique [0002] According to the intelligent requirements of my country's power supply network, it is necessary for the terminal actuator of the power supply network - the small circuit breaker to have the function of tripping and closing when executing the upper-end signal; Electric remote control function. Therefore, manually operated circuit breakers can no longer meet the requirements of the smart grid. It is necessary to match the circuit breaker products specially used for prepaid meters, which can realize automatic reclosing operation, transmit a control signal, and realize remote control, so that the circuit breaker can be automatically operated. Closing or opening, instead of requiring staff to manually open and close the operation, effectively saving manpower and...
