Problems solved by technology

With the development of smart grid, higher requirements are put forward for the functions of circuit breakers. The existing intelligent controllers of circuit breakers are generally based on microprocessors such as single-chip microcomputers and DSPs. The functions are mainly based on basic three-stage protection. Differentiate by priority, complete the task with the highest priority first, and complete the tasks with gradually decreasing priority in turn. This implementation method can no longer meet the requirements of the smart grid for circuit breakers

Abstract

The invention discloses a circuit breaker intelligent control device; the performance of a circuit breaker is enhanced by adding a microprocessor which supports an embedded operation system and relevant functional modules on a traditional circuit breaker and operating a Linux embedded operation system, so that the circuit breaker can monitor various mechanical and non-mechanical parameters in real time based on a traditional protection function.

Description

technical field [0001] The invention relates to an intelligent control device for a circuit breaker, which belongs to the field of circuit breakers. Background technique [0002] The circuit breaker is an important electrical equipment for the protection and control of the power system. The reliability, real-time performance and stability of its operation are directly related to the safety and stability of the power system. In recent years, circuit breakers have developed rapidly, which is mainly reflected in the intelligence of its control unit and real-time online detection. With the development of smart grid, higher requirements are put forward for the functions of circuit breakers. The existing intelligent controllers of circuit breakers are generally based on microprocessors such as single-chip microcomputers and DSPs. The functions are mainly based on basic three-stage protection. Differentiate by priority, complete the task with the highest priority first, and comple...
