Intelligent quick emergency power system as shown in Figure 2, changing the road device by emergency power supply and intelligent quick power supply forms, emergency power supply can be selected UPS or EPS or sinewave inverter for use according to the characteristic and the site environment needs of load, mainly comprises rectification link, charging and discharging link, sinusoidal wave inversion link and batteries.Be divided into two-way behind the electric network source process service entrance switch ATS, one the tunnel with emergency power system series connection after be connected quick power supply and change the road device, another road directly connects quick power supply and changes the road device, power supply changes main contacts switch C1 and the C2 difference noncontacting switch K1 in parallel and the K2 of road device fast, AC contact-less switch K1, K2 can adopt silicon controlled module or IGBT module or IPM module class power electronic device (comprising IGCT.GTR.GTO.P-OSFET etc.), total string, connect with out-put supply as total output in the shunt circuit, contact switch and noncontacting switch are controlled by intelligent control board IPC all, intelligent control board IPC can adopt PLC, single-chip microcomputer, industrial computer or General Logic control circuit all can, be connected with input power parameter checkout gear IA1 on the intelligent control board IPC, IA2 and IA3, power parameter checkout gear IA1, IA2 and IA3 can adopt voltage changer, voltage transformer, power pack, intelligent detection module, fuzzy detection module, AC/DC module or AC/AC module, transformation-rectification-filtering-sample circuit etc.
During application, change at power supply fast according to the principle of " net electricity preferential " generally that C1 is set to working power switches set (directly being connected main power source) with K1 in the device of road, and C2 and K2 are set to Backup Power Switch group (scooping out the urgent telegram source output terminal), and emergency power supply and main power source directly join.The intermediate dc one tunnel of its rectifier output is given batteries charging through charger, and one the tunnel connects the inverter input, and inverter output (being emergency power supply output) end connects Backup Power Switch group C2 and the K2 in " intelligent quick power supply changes the road device ".C1 is in " leading to " attitude under the normal condition, C2 is in " breaking " attitude, K1 and K2 all are in cut-off state, inverter under normal circumstances is in unloaded output state all the time, parameters such as its output voltage, waveform detect and are real-time transmitted to IPC in real time by IA2, the bypass of urban network electricity source crosses emergency power supply, by the main contacts C1 powering load of " intelligent quick power supply changes the road device ", parameters such as its input voltage, waveform, frequency detect and are real-time transmitted to IPC in real time by IA1.Intelligent control board IPC online in real time receives and handles the electric network source parameter that transmits through IA1, when finding electric network source parameter substantial deviation standard value, the working power switches set of meeting control " intelligent quick power supply changes the road device " and Backup Power Switch group realize conversion automatically, and (it is disconnected that transfer process: K1 leads to C1, the disconnected K2 of K1 is logical, the logical K2 of C2 breaks), this moment, electric network source powered to the load through rectification, filtering, voltage stabilizing, each link of inversion of emergency power supply.Emergency power supply works online to export and replaces the urban network electricity source directly to export, and the parameter of its out-put supply improves.If have a power failure then after parameter degenerates as the urban network electricity source, then the output of emergency power supply is uninterrupted, and its energy is provided by battery.If directly have a power failure after the parameter drift-out standard of urban network electricity source, then system can directly change fast for (uninterrupted conversion) emergency power supply, up to intelligent control board IPC in real-time online receives and handle the process of IA1, IA2, find urban network electricity source parameter recover normal after, just according to the principle control system of " the net electricity is preferential " revert to the net electricity directly through " intelligent quick power supply changes the road device " to electric (the logical C2 of conversion sequence: K2 is disconnected, the disconnected K1 of K2 is logical, the logical K1 of C1 disconnected).In like manner, also can C2 and K2 in " intelligent quick power supply changes the road device " be arranged to main electric switch group and C1 and K1 are arranged to the Backup Power Switch group according to the principle of " emergency power supply is preferential ", at this moment intelligent quick emergency power system is online output emergency power supply under normal circumstances, and changes when emergency power supply output parameter substantial deviation standard value for the electric power supply of net.Its quick transfer principle is constant, and (summary) is described roughly the same.
When the output short circuit causes the outage of main power source breaking, intelligent control board IPC in " intelligent quick power switcher " obtains short circuit information by output monitoring device IA3 and stops the conducting and the conversion of two groups of switches in the system in view of the above, guarantees that emergency power supply can not miscarry on the circuit of short trouble.
