Abstract
The utility model provides an alarm device of an AC power source distribution unit used for communication. The alarm device of the AC power source distribution unit used for communication includes an alarm processing board, a signal collecting board and a connection cable. The signal collecting board is composed of multiple photoelectric isolating detection circuits. A detection terminal of the signal collecting board is connected to a lower end of a circuit breaker or a fuser of a protection component in parallel. The lower end of the protection component circuit breaker or fuser is a load terminal. The signal collecting board monitors electric potential changes of the lower end of the protection component. When the protection component trips or burns, a voltage difference between the electric potential of the lower end and the electric potential of a power source input terminal is generated, thereby switching on a photoelectric coupler in the detection circuits. An alarm signal is amplified by the circuits and then transmitted to the alarm processing board. The alarm processing board sends a hearable and visible sound light alarm signal. According to the utility model, a traditional fault collecting method adopting a circuit breaker and auxiliary alarm contacts is replaced with a method of detecting electric potentials on two ends of the protection component. Thus, installation space of the auxiliary alarm contacts can be saved. The systematic integration is improved and the system cost is reduced.
