| Abstract: | The current middle-low voltage bus bar protection devices and its shortcomings were analyzed. An electric arc light protection device combined arc light, arc sound with short circuit current as criterion of arc fault was introduced . The protection device can avoid malfunction of fault clearing, making fauit quickly removed to ensure the safe and stable operation of system. Using optical fiber technology in protection to transmit trip signal to main unit ensures perfect function of electric arc protection system and trip signal can be very quickly outputted to breaker. Finally, we illustrate the necessity of arc light protection for areas of application in middle-low voltage switchgear and rectifier cabinet. |
