紧急通风逆变器检测控制箱
摘要：
本实用新型公开了一种紧急通风逆变器检测控制箱，包括检测控制箱主体，所述检测控制箱主体内设置有控制箱电源电路、与逆变器电源输入端连接的逆变器电源电路、与逆变器运行状态输出端连接的状态指示电路、与逆变器电源输出端连接的检测电路和通风机驱动电路。本实用新型可在地铁电客车紧急通风逆变器损坏后，就地快速的对其进行检测，且能显示逆变器“RUN”/运行”、“FAULT”/“故障”等输出信号，而且还能连接通风机，显示紧急通风逆变器输出电压和频率。
摘要（英）：

The utility model discloses a dc -to -ac converter that promptly ventilates detects control box, including detecting the control box main part, the state indicating circuit that detects the dc -to -ac converter power supply circuit that is provided with control box power supply circuit in the control box main part, is connected with dc -to -ac converter power input end, be connected with dc -to -ac converter running state output, hold detection circuitry and the expert fan drive circuit who is connected with dc -to -ac converter power output. The utility model discloses can promptly ventilate the dc -to -ac converter at the ferroelectric passenger train in ground and damage the back, detect it fast on the spot, and can show dc -to -ac converter " RUN " operation ", " FAULT " output signal such as " troubles ", but also can connect the ventilation blower, demonstration promptly ventilate inverter output voltage and frequency.
