Abstract

The invention relates to an arc current intelligent detection module and a working method thereof. The arc current intelligent detection module comprises a DSP processor, wherein the DSP processor iselectrically connected with an analog-to-digital converter, a multi-channel current detecting module, a multi-channel arc detecting module, a power input and differential voltage acquisition module, acircuit breaker state switching value input module, a switching value output module, an analog quantity input module, a nixie tube, a key module and a burning port. The arc current intelligent detection module is mainly applied to occasions of DC power transmission, distribution and the like, such as a photovoltaic combiner box, a DC cabinet, a telecommunication machine room and a communication base station, monitors current, bus voltage, box body temperature, lightning arrester state, DC circuit breaker state and the like of each branch circuit in a DC system in real time, detects whether aharmful arc occurs in a DC circuit in real time, if so, sends out an alarm signal immediately, and effectively prevents potential safety hazards such as fire caused by the arc.

Description

technical field [0001] The invention relates to the field of arc current detection modules, in particular to an arc current intelligent detection module. Background technique [0002] Standards in the solar industry are constantly being revised as photovoltaic technology matures and manufacturers expand into new markets. As large "solar fields" of large numbers of solar panels continue to evolve into increasingly smaller residential and commercial installations, there is an increasing need to implement safety measures to avoid catastrophic events related to high voltages, such as electric shock or fire. These events are caused by arcing, which can occur on high voltage DC lines when a line or electrical connection fails, and these arcs can energize the unit, energize the rack system, and potentially shock anyone who comes into contact with the unit, and These arcs can also cause fires, resulting in damage to electrical equipment, or extensive property damage. However, the ...
