Problems solved by technology

The device adopts an electric device to improve the predicament in the operation process. However, since the moving and static contacts of the handcart switch require a large force during the opening and closing process, the structure of the device is used in the power transformation and distribution environment where a large number of female workers work. Due to the ease of handling and force, it cannot be better applied

Abstract

The invention discloses an electric crank for a handcart-type switch cabinet and relates to the technical field of power supply and distribution equipment. The electric crank comprises a handle, a rocker arm and a crank head, wherein the crank head comprises a sleeve structure, a two-way ratchet mechanism, a planetary gear mechanism and an electric structure. With adoption of the handle, the defect that holding and stress are inconvenient in the prior art is overcome, and the electric crank is convenient to mount and has manual and electric dual-purpose effect.

Description

technical field [0001] The invention relates to the technical field of power supply and distribution equipment, in particular to an electric crank for a handcart type switch cabinet. Background technique [0002] The handcart switchgear has three positions of operation, test and maintenance. The switch between the operating position and the test position requires the operator to drive the handcart rocker arm to rotate by shaking the handle on the handcart handle, and then make the handcart crank The rear end of the arm is connected by a spring-loaded detent and rotates on a central axis located in the cabinet. The operator turns the handle to drive the screw to rotate, so that the switchgear trolley moves back and forth. When the trolley switchgear is in the operating position, the moving contacts on it are connected to the static contacts on the bus; when the trolley switchgear is in the test position, the moving and static contacts are separated. However, during the swit...
