Problems solved by technology

Since the double-breakpoint universal circuit breaker requires the operating mechanism to provide twice the closing force than the single-breakpoint, the current operating mechanism cannot meet this requirement.
This is also a major technical obstacle restricting the successful development of double breakpoint universal circuit breakers

Abstract

The invention relates to a novel operation mechanism of a double-breaking-point air circuit breaker. The novel operation mechanism of the double-breaking-point air circuit breaker is composed of an operation mechanism body, a manual energy storage device and a rotating shaft. The manual energy storage device is located on one side of the operation mechanism body and is used for manual energy storage. The rotating shaft is used for driving the operation mechanism body to rotate. The operation mechanism body comprises a left side, a U-shaped piece, a mechanism action portion, a left side plate, an energy storage indicator, a closing button, an opening button and an opening and closing state indicator. The mechanism action portion is installed in a section defined by the left side plate, the U-shaped piece and the right side plate. The energy storage indicator, the closing button, the opening button and the closing and opening state indicator are all located on the same end face of the mechanism action portion. The closing and opening state indicator are arranged above the opening button. The energy storage indicator is arranged above the closing button. The closing button capacity of the novel operation mechanism is quite high, and the opening and closing action requirement of the double-breaking-point air circuit breaker can be reliably met.

Description

technical field [0001] The invention belongs to the field of electromechanical technology, and in particular relates to a novel operating mechanism of a double-breakpoint universal circuit breaker. Background technique [0002] The existing universal circuit breaker technology has a history of nearly one hundred years, and no one can make a substantive breakthrough on this basis at present. Over the years, people have been trying to realize the double break point function on the universal circuit breaker, but they are difficult to produce because some major problems cannot be solved. Since the double-break universal circuit breaker requires the operating mechanism to provide twice the closing force than the single-break, the current operating mechanism cannot meet this requirement. This is also a major technical obstacle restricting the successful development of double breakpoint universal circuit breakers. Contents of the invention [0003] The object of the present inv...
