Abstract

A control circuit of double power supply automatic converting switch is prepared as forming control circuit mainly by two double master-slave diode D triggers and four two-input Nor gates; using input end of control circuit to receive fire fighting signal and spacing switch signal; connecting control circuit separately to detection circuit of normally used power supply, detection circuit of spare power supply and control circuit power supply; connecting output end of control circuit to double power supply automatic converting switch.

Description

technical field [0001] The invention relates to a power supply control device, in particular to a dual power supply automatic transfer switch control device. Background technique [0002] At present, most of the dual power automatic transfer switches use electronic control devices. According to the current requirements of relevant national and industry standards, dual power supplies should be used for some important primary and secondary loads; however, the power supply for fire control rooms, fire pumps, fire elevators, smoke prevention and exhaust fans in high-rise buildings should be An automatic switching device is installed at the last level of distribution box. In order to ensure the continuity of power supply for important loads, the application requirements of dual power automatic transfer switch appliances are becoming more and more extensive, and the technical performance requirements are also getting higher and higher. The performance and reliability of dual powe...
