Problems solved by technology

[0003] The traditional way to realize circuit breaker state feedback is to provide signal mechanism from the body to feedback the state. There is a space in the electric operation of the large frame to easily realize the installation and arrangement of the signal mechanism, but in most small frame electric In operation, due to the limitation of space size, it is difficult to arrange the signal mechanism

Abstract

The invention relates to an indication transition structure for an electric operating mechanism, which comprises a state indication piece, a conversion part, an indication ejector rod and a mounting plate, and is characterized in that the state indication piece is rotationally connected to the mounting plate through a second connecting shaft; the switching component is made of elastic materials, one end of the switching component is connected to the state indicating piece, the other end of the switching component is connected to the indicating ejector rod, the middle of the switching component is wound around the first connecting shaft and can twist around the first connecting shaft, the indicating ejector rod is installed on the installation plate, and the switching component is connected with the indicating ejector rod. And the base can move up and down relative to the mounting plate. The invention provides a transition structure which is simple and convenient to install and small in space structure for an indicating device of a small shell frame electric operator, so that the signal mechanism is simple to operate during assembly and safe and reliable to use, and the on-off state of a circuit breaker can be indicated in real time on an electric operating mechanism.

Description

technical field [0001] The invention belongs to the technical field of electrical machinery and equipment manufacturing, and in particular relates to an indication transition structure for an electric operating mechanism. Background technique [0002] With the development of the electric power industry, the operating mechanism of molded case circuit breakers has gradually become the mainstream of current development, and the design is developing in the direction of miniaturization and intelligence. As an electric operating mechanism for power distribution, its performance should not only meet the basic functions of the electric operating mechanism, but also be able to accurately feed back the real-time status of the circuit breaker body in real time. [0003] The traditional way to realize circuit breaker state feedback is to provide signal mechanism from the body to feedback the state. There is a space in the electric operation of the large frame to easily realize the insta...
