Problems solved by technology

[0008] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the detection range of the three position sensors in the circuit breaker in the prior art is small, the arrangement is too concentrated, and there is a risk of false detection, so as to provide a circuit breaker with a relatively small detection range. Large, electric operating mechanism of the circuit breaker that eliminates the risk of false detection

Abstract

The invention provides an electric operating mechanism of a circuit breaker. The electric operating mechanism comprises a housing, a transmission shaft, a driving device, a striking device, a position detection device and an electric control device, wherein the position detection device comprises a switch-on position detection device, a switch-off position detection device and a free position detection device; the switch-on position detection device and the switch-off position detection device are arranged on the two sides around the transmission shaft; and the free position detection device is arranged at the driving device far away from the transmission shaft. Distribution of the position detection devices is relatively disperse; the position detection devices are free from false detection when a first detection object and a second detection object are respectively detected; and a detection range is large due to the arrangement manner of the position detection devices.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an electric operating mechanism of a circuit breaker. Background technique [0002] With the continuous improvement of the speed of smart grid transformation and upgrading, State Grid and China Southern Power Grid have simultaneously proposed application requirements and related specifications for reclosing products in the field of photovoltaics and household appliances; at the same time, with the continuous popularization of smart homes in people's lives, more and more The products tend to be remote automatic control.
