Description of drawings
Fig. 1 the utility model fire-fighting equipment emergency power supply circuit diagram.
Embodiment
The present invention is described in detail below in conjunction with drawings and Examples.
With reference to Fig. 1, described fire-fighting equipment emergency power supply comprises: charger, battery pack, three-phase electricity detection module, inversion/frequency-variable module, active and standby switching controller and hand/automatic module.
Described charger, battery pack, inversion/frequency-variable module, active and standby switching controller and hand/automatic module are connected successively; The input of rectification module is connected with charger, and output is connected with inversion/frequency-variable module; Described three-phase electricity detection module is connected with the input of rectification module; The output of described inversion/frequency-variable module is respectively at being connected with the first fire-fighting equipment, the second fire-fighting equipment; KM1/KM2 connects inversion/frequency-variable module lead-out terminal, and its first fire-fighting equipment that connects respectively, the second fire-fighting equipment are controlled; Battery pack is connected with KM3 through circuit breaker, and the KM3 output connects inversion/frequency-variable module through isolating diode, and the control battery pack is to inversion/frequency-variable module power supply.
Operation principle: provide direct current through rectification to inverter when three-phase input electricity is normal, charger is to batteries charging simultaneously; If when three-phase is inputted the electricity power failure or is lower than 380V X(1-15%) time, the KM3 adhesive provides direct current by battery pack to inverter.When the needs motor load is worked, give enabling signal (such as run signal, Long-distance Control, fire-fighting through transport signal), inverter is exported immediately.Carry out variable frequency starting from 0HZ-50HZ frequency conversion electric energy to motor, after its frequency arrives 50HZ, keep normal operation.Manual/auto selective switchgear, can carry out Long-distance Control and fire-fighting through transport (DC24V) operation at automated location, can carry out in-local in manual position, this moment, Long-distance Control and fire-fighting through transport can not operate, and run signal can be monitored with manual or automated location fire-fighting center.
