Low voltage circuit breaker

Abstract

The invention discloses a low voltage circuit breaker. The low voltage circuit breaker comprises an acquisition module and a protection module. The acquisition module is used to realize acquisition and calculation of electrical parameters such as current, voltage, active power, passive power, electric energy quantity, and frequency. The internal software of the acquisition module has a self-learning function, and pseudo data and interference signals are identified automatically, and accuracy and precision of signal acquisition are guaranteed. Based on information and data provided by the acquisition module, the protection module is used to determine faults such as overcurrent, overvoltage, undervoltage, and leakage current quickly in a cycle (within 20ms) by adopting a rapid fault determining algorithm, and is used to analyze motion results and record fault data quickly. Compared with the prior art, the low voltage circuit breaker is advantageous in that acquisition of electrical data of a switch position is realized, and the protection module is used to read the data from the acquisition module, and is used to determine the fault type by using the algorithm, and therefore the multifunctionality and the intelligentization of the circuit breaker are facilitated.

AI Technical Summary

Problems solved by technology

[0003] The current low-voltage circuit breakers are based on the principle of bimetal overcurrent heating deformation, which cannot collect current and voltage signals, so current, voltage, power, electricity, etc. cannot be realized.

It is also impossible to set multi-dimensional thresholds and programmable protection and control, let alone realize remote information interaction and control
