Power supply abnormity alarming device of double-circuit power supply system

Abstract

The invention discloses a power supply abnormity alarming device of a double-circuit power supply system. The power supply abnormity alarming device comprises a first alarming control circuit and a second alarming control circuit. The first alarming control circuit comprises a first bipolar circuit breaker, a first relay, a second relay, a first alarm lamp, a second buzzer and a second resetting button. The second alarm control circuit comprises a second bipolar circuit breaker, a third relay, a fourth relay, a second alarm lamp, a first buzzer and a first resetting button. The inlet of the first bipolar circuit breaker and the inlet of the second bipolar circuit breaker are correspondingly connected with the double-circuit power supply system. The power supply condition of the power supply system is determined through the relays. When power supply abnormity occurs, the contacts of the relays and the buzzers perform alarming. Because the alarm device can be independently mounted in a random area, maintenance personnel can be reminded of eliminating the fault and reducing loss in time.

Description

technical field [0001] The invention relates to the technical field of power supply for enterprise equipment, in particular to a power supply abnormal alarm device for a dual-way power supply system. Background technique [0002] Enterprises or places that have high requirements on power supply quality, or that abnormal power supply will cause heavy losses generally adopt dual-circuit power supply systems, such as most flat glass manufacturers. [0003] The reason why these enterprises or places use dual-circuit power supply, on the one hand, shows that they have high requirements on the quality of power supply, and do not want losses caused by abnormal power supply. On the other hand, it also shows that the power supply system is not so reliable, and there is always the possibility of abnormalities. [0004] When the power supply is abnormal, the enterprise will have an emergency response plan, and the relevant personnel will carry out a series of operations to minimize the...

And these devices are often scattered everywhere, which causes that when the power supply of the enterprise is abnormal all the way, the equipment in the area where some personnel are located may have normal power supply, and not all personnel can know the occurrence of abnormal power supply at the first time, and cannot find out in time Faults, and then can not quickly deal with faults, resulting in unnecessary losses
