Device and system used for detecting implosion and flash fire of capacitor

The utility model relates to a device and a system used for detecting implosion and flash fire of a capacitor. The device comprises a voltage detection unit, an AD conversion unit, a single-chip microcomputer, a data storage unit, a data transmission unit, an upper computer, and a power supply module unit. The voltage detection unit is connected with the single-chip microcomputer by the AD conversion unit, and the data storage unit is connected with the single-chip microcomputer. The single-chip microcomputer is connected with the upper computer by the data transmission unit, and the upper computer is used to transmit the control information to the single-chip microcomputer by the data transmission unit, and is used to receive the signals output by the single-chip microcomputer via the data transmission unit. The AD conversion unit, the single-chip microcomputer, the data storage unit, and the data transmission unit are connected with the power supply module for the power supply. The device and the system used for detecting the implosion and the flash fire of the capacitor are advantageous in that the implosion and the flash fire of the capacitor can be effectively detected; the structure is simple, the use is convenient, and the performance is very stable.
