A large integrated manual and electric operation closing and opening device

Abstract

The invention discloses a large-scale integrated hand-operated and electric-driven operation brake separating and closing device, and relates to an integrated operation brake separating and closing device. The device comprises a motor, wherein a reduction gearbox is mounted on an output shaft of the motor; a one-way bearing is mounted at an output end of the reduction gearbox; an electric-driven passive gear is mounted on the one-way bearing; an electric-driven driving gear matched with the electric-driven passive gear is arranged on the reduction gearbox; a manual operation handle is mounted on a one-way bearing on the inner side of the electric-driven passive gear; a connecting board is mounted on a one-way bearing on the outer side of the electric-driven passive gear; an eccentric shaft connecting pin is arranged on the connecting board; one end of a connecting rod is connected with the eccentric shaft connecting pin; the other end of the connecting rod is mounted with a connecting part; the connecting part is mounted on a breaker lever. The device has the advantages that the hand-operated brake separating and closing and the electric-driven brake separating and closing of a breaker can be realized, the practical operation is convenient, and safe electricity supply and electricity utilization are realized.

Description

technical field [0001] The invention relates to an integrated operation closing and opening device, in particular to a large-scale integrated manual and electric operation [0002] The closing and opening device is installed in the molded case residual current circuit breaker and circuit breaker. Background technique [0003] 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 consumption. [0004] 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 break...

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

[0004] 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.
