Novel electric crank of high-voltage switch cabinet

Abstract

The invention discloses a novel electric crank of a high-voltage switch cabinet, wherein the novel electric crank comprises a handheld machine shell, a power assembly and a power source are arranged in the handheld machine shell, an output shaft of the power assembly is fixedly connected with a lock head, the lock head comprises a lock shell, a double-layer limiting plate is fixed in the lock shell, and a plurality of through holes are formed in the double-layer limiting plate. A lock column is slidably connected into each through hole, a reset spring is connected to the tail end of each lockcolumn, one end of each reset spring is fixed into the lock shell, and the power source supplies power to the power assembly. According to the invention, the original sleeve is replaced by the lock column structure in array distribution, and a fixing device is additionally arranged, so that the opening and closing operation of a vacuum circuit breaker of the handcart type high-voltage switch cabinet is controlled, and the operation is efficient and labor-saving.

Description

technical field [0001] The invention relates to the technical field of handcart switch cabinets, in particular to a new electric crank handle for high-voltage switch cabinets. 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 switching p...

Problems solved by technology

[0003] The invention solves the problem that the existing handcart-type switch cabinet electric crank requires multiple sets of sleeves, and a sleeve cannot be clamped to different types of joints, and at the same time solves the problem that the existing handcart-type switch cabinet electric crank is lacking. Fixing device, the problem of laborious hand-held operation, a new type of electric crank handle for high-voltage switchgear is proposed, which uses an array-distributed lock column structure to replace the original sleeve, and is equipped with a fixing device to realize the car-type high-voltage switchgear. The control of the opening and closing operation of the vacuum circuit breaker is efficient and labor-saving
