Disadvantage (2): It can only use the three-stage charging method of constant current equalization charging stage, constant voltage equalizing charging stage, and trickle floating charging. Conducive to the self-management and maintenance of the battery system, resulting in the plate of the battery system being easily vulcanized, the capacity of the battery system is reduced, and the service life is short

The invention relates to a UPS power-supply multi-static-state combined realizing multi-class load power supply system and belongs to the power supply technology field of an alternating current and direct current mixing load of multi-static-state conversion. The system of the invention is used to mainly solve problems that a direct-current static state change over switch and an alternating-current static state change over switch cannot cooperatively work and a cell system pole plate is easy to be vulcanized. The system comprises a main alternating-current loop, a standby alternating-current loop and a cell loop. The main alternating-current loop comprises a main alternating-current work power supply, a rectifier, an inverter and a static state switch II which are successively connected. The main alternating-current loop is connected to an alternating-current load. The standby alternating-current loop is connected in parallel with the main alternating-current loop. The standby alternating-current loop is connected to the alternating-current load through a static state switch I. The cell loop comprises a cell system. The cell loop is connected to the main alternating-current loop, comprises a static state switch III and carries out coordination action with the alternating-current static state switch. The rectifier of the UPS power supply system is fully used so that an extra investment of a direct-current power supply is saved and a service life of a cell system is prolonged.
Description
Technical field [0001] The invention relates to a multi-static combination of UPS power supplies to realize a multi-type load power supply system, and belongs to the technical field of power supply for AC / DC mixed loads with multi-static conversion. Background technique [0002] The static transfer switch is mainly used for two-way power supply switching, which is an automatic switching system for power supply. At present, there are only AC static transfer switches in the UPS power system. Generally, two AC contactors and a set of triacs (single static) or two sets of triacs (double static) are used to realize inverter output and backup. Switching between AC power sources. When the power output from the inverter is within the normal voltage range, the load is always connected to the inverter power supply. When the inverter power fails, the static transfer switch automatically switches it to the standby AC power supply. After the inverter power returns to normal, the static tran...
