Embodiment 1

[0012] Embodiment 1 is a typical embodiment, which is explained in conjunction with accompanying drawings 1-3. There are two left and right escapement clips 505, two circuit breaker handles 503, Two photo-interrupters 504, the two escapement clips respectively clamp the respective circuit breaker handles to perform electrical operations of "opening" and "closing" to connect and break the circuit; this embodiment is in the escapement clip Add a light through hole 501 and install a photoelectric interrupter 504 at the position of the escapement clamp light through hole 501 when the circuit breaker performs the electrical operation of "closing"; When the position of the through hole 501 reaches the photoelectric interrupter 504, the photoelectric interrupter outputs an electrical signal to provide the controller with a position signal of the circuit breaker when the light passes through the optical through hole. The controller issues work instructions to the motor of the operatin...

Embodiment 2

[0013] The technical solution of embodiment 2 is improved as follows: the light through holes on each escapement clip are a series of light through holes on the route passing through the photoelectric interrupter. Further provide the controller with the position signal in the movement of the handle of the circuit breaker, so that the speed of the handle movement can be read, so as to detect the running state of the motor and the operating mechanism, which provides the possibility for the controller to judge the failure of the motor and the operating mechanism , and can provide solutions in the early stages of the agency and when the work fails. , the design of optical through holes, optical through hole strings, and gratings in the follow-up improvement scheme provides the possibility for the controller to judge the faults of the motor and the operating mechanism, and can provide solutions when the mechanism is early and the work fails.

Embodiment 3

[0014] The technical solution of embodiment 3 is further improved as follows: each escapement clip has a grating, and when the escapement clip moves, the grating provides the controller with an electric pulse sequence through the photointerrupter, and the controller can judge the movement of the motor and the operating mechanism The speed and position of the breaker handle, the controller can further provide precise control to greatly improve the performance of the dual power switching device, and derive the function of fault analysis.

Abstract

The invention discloses a method and an apparatus for positioning a work position of a circuit breaker of a double power source switching device. The technic scheme of the invention is that: signal detection and logic processing are combined and solved in a weak electrical loop by a photoelectric scheme to increase the reliability and electromagnetic compatibility of the double power source switching device.

Description

technical field [0001] The invention belongs to the field of low-voltage electrical appliances and relates to a dual power switching device, in particular to a positioning method for a dual power switching device. Background technique [0002] In order to improve the power quality of the power supply grid, when the power supply fails, the dual power switching device can switch another backup power supply to the power supply circuit to ensure the normal operation of the electric appliances. A general dual power switching device consists of two circuit breakers, electric and manual operating mechanisms, a position detection master switch, and a controller. The dual power supply switching device is controlled by two circuit breakers to connect and disconnect the respective power supplies, the electric or manual operating mechanism is used to operate the mechanical action of the circuit breaker, and the position detection master switch detects the position of the circuit breaker...
