Photovoltaic solar connection board with function of high speed circuit breaker

The present invention includes a high-speed lockout capable of detecting an arc generated in circuit breaker or the connection of the internal PV connection half is a channel, and shorten the amount of time to generate a signal to trip the circuit breaker based on the detected signal one aspect relates to optical connecting half. Having a high-speed lockout according to the present invention in order to solve the above photovoltaic connection half solar connection half is provided inside the connecting portion, the power device and a plurality of loop sensor and an abnormal current detecting an arc generated in a power line sensor unit comprising a current sensor for detecting; A / D converter for converting the respective analog signals corresponding to the respective output for each sensor the sensor section into a digital signal; Level adjusting unit to adjust the sensitivity of the loop sensor and a current sensor; FPGA block unit for outputting a trip signal applied to the circuit breaker depending on the sensing signal based on a sensitivity level set in the control unit output from the sensor unit; And a display unit for displaying the control signal output from the FPGA block unit; A / D receiving module comprising: a, the FPGA block unit receiving the digital signals inputted from the A / D converter; Digital filter module that filters the digital signal received by the A / D receiving module; And when it is determined to be the arc compared to analyze the sensitivity is set in the digital signal and the level control portion filtered by the digital filter module, it characterized in that it comprises a control module for outputting a trip signal to operate the trip coil of the circuit breaker .
