Embedded thread type intelligent induction contact arm for intelligent circuit breaker

Abstract

The invention relates to the technical field of circuit breakers, and discloses an embedded thread type intelligent induction contact arm for an intelligent circuit breaker, which comprises a base and an ARM system, is simple in structure and novel in design, carries out comprehensive diagnosis on the state of the circuit breaker through a Hall sensor, a displacement sensor, a motion sensor, an energy sensor and a temperature monitoring unit, and improves the detection accuracy. Whether each link of the circuit breaker is normal or not and whether the insulation state is good or not are obtained, alarming and processing are carried out on abnormal conditions, and mechanical parameters such as opening and closing displacement waveforms, opening and closing speed and the like after each time of opening and closing can be displayed through a friendly man-machine touchable interface of the display. Checking a complete current waveform curve of circuit breaker opening and closing coil current and energy storage motor current; operation temperature parameters and the like of the plum blossom contact of the circuit breaker can be checked in real time, faults are handled manually or automatically, a multi-priority interrupt service mechanism is adopted, the real-time performance of control is improved, and the system is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an embedded threaded intelligent sensing contact arm for an intelligent circuit breaker. Background technique [0002] A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy and start asynchronous motors infrequently. It can automatically cut off the circuit when serious overload, short circuit and undervoltage faults occur. Its function is equivalent to the combination of fuse switch and over...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an embedded threaded intelligent sensor arm for an intelligent circuit breaker, capable of comprehensively diagnosing the state of the circuit breaker, and obtaining whether each link of the circuit breaker is normal, whether the insulation state is good, and In case of abnormal situation, alarm and deal with it. The monitor has a friendly man-machine touch interface, which can display the opening and closing displacement waveform, opening and closing speed, and other mechanical parameters after each opening and closing, and check the opening and closing of the circuit breaker. The complete current waveform curve of coil current and energy storage motor current can check the operating temperature parameters of the circuit breaker plum blossom contact in real time, and manually or automatically process the fault. The multi-priority interrupt service mechanism is adopted to improve the real-time control It solves the problem of inconvenient comprehensive diagnosis of the state of the circuit breaker, inconvenient detection of whether each link of the circuit breaker is normal, whether the insulation state is good, inconvenient alarm and processing for abnormal situations, and inconvenient real-time viewing of the plum blossom contact of the circuit breaker The operating temperature parameters of the head, etc. cannot be manually or automatically processed for faults, and the real-time performance of the control is low
