Small-size manual-electric integrated switching-on and switching-off device

Abstract

The invention discloses a small-size manual-electric integrated switching-on and switching-off device, and relates to a switching-on and switching-off device. The small-size manual-electric integrated switching-on and switching-off device comprises a motor. The motor is connected with a speed reducing box, a one-way bearing is mounted on the output end of the speed reducing box, an output wheel is sleeved on the one-way bearing, and one-way teeth are engraved on the outer circle of the output wheel. A manual operating handle is mounted on the one-way bearing between the output wheel and the speed reducing box, an automatic one-way clutch matched with the output wheel and a reset spring are mounted on the manual operating handle, the reset spring presses the automatic one-way clutch on the one-way teeth of the output wheel, and the rotating direction of the manual operating handle is opposite to that of the output wheel. An eccentric driving connecting pin is mounted on the outer side surface of the output wheel, an operation connecting rod is mounted on the eccentric driving connecting pin, and a transition member is mounted at the other end of the operation connecting rod and on a breaker lever. The small-size manual-electric integrated switching-on and switching-off device has the advantages of manual-electric integrated design, convenience in operation and capability of supporting remote operations.

Description

technical field [0001] The invention relates to a closing and opening device, in particular to a manual and electric integrated operation closing and opening device, which is installed in a molded case residual current circuit breaker and a circuit breaker to realize manual closing and opening of the circuit breaker, and electric closing and opening. , Opening, to expand the function of the circuit breaker, realize remote control, provide convenience for actual operation, and realize safe power supply and electricity consumption. Background technique [0002] There are no more than two closing methods for molded case circuit breakers and circuit breakers currently on the market. A method of manually driving the closing and opening handle of the molded case circuit breaker to realize closing and breaking; this operation method has great unsafe hidden dangers, and accidents of varying degrees have occurred in the market, and it cannot realize power supply and automatic power c...

Problems solved by technology

A hand-driven molded case circuit breaker to close and open the handle to realize closing and breaking; this operation method has great unsafe hidden dangers, and accidents of varying degrees have occurred in the market, and it cannot realize power supply and automatic power consumption

[0003] The second is to add an electric operating mechanism to the molded case circuit breaker to operate the closing and opening of the circuit breaker, which can realize the remote closing and opening of the circuit breaker; it provides convenience for safe and automatic power supply and use, but the volume is large and the electric When operating the closing and opening, the electric clutch must be manually connected first, and then the closing can be operated electrically

The switch is closed manually, and the electric clutch can be closed manually before the switch is manually separated, which brings inconvenience to the operation.
