With reference to Fig. 3, this is the leakage protection circuit schematic diagram of the control device of fire pump stabilized pressure pump of the present invention.
In up-to-date regulation, the fire-fighting control device should possess warning function of electric leakage.
Therefore, the present invention realizes warning function of electric leakage by increasing by two leakage relays.
When the general service pump electric leakage, general service pump electric leakage indicator light is bright, continues operation; When stand-by pump also leaked electricity, stand-by pump electric leakage indicator light was bright, sent alarm bell simultaneously and reported to the police.Simultaneously signal is delivered to central control room.
Leakage protection circuit comprises two leakage relays, switch and indicator lights.
The operating current of leakage relay of the present invention is that 50-500mA is adjustable continuously.
With reference to Fig. 4, this is the overload function realization schematic diagram of the control auto levelizer of fire pump stabilized pressure pump of the present invention.
Described overload protection function circuit, overload protection function circuit divide two groups, control general service pump and stand-by pump respectively.
In fire-fighting system, to protect the normal use of fire pump on the one hand, the more important thing is that the maintenance system gets operate as normal.When the general service pump overload fault, general service pump be disconnected, stand-by pump puts into operation; But when stand-by pump also transships, stand-by pump can not be disconnected, must continue operation, guarantee the reliability of fire-fighting to guarantee the normal operation of fire-fighting system.
The system of fire control type is mainly used in the electric current that exchanges under the overload condition that 50HZ (60HZ), rated voltage comprise regulation to 690V, electric current connection in the fire-fighting system important load of 0.16A to 100A, carrying and the disjunction normal condition, " only report to the police, do not trip " when realizing overload, overcurrent, the phase failure, also can connect simultaneously, carrying and disjunction non-normal condition electric current (as short circuit current) down, " report to the police and also trip " when realizing short circuit.
The overload control procedure is as follows: when general service pump fault (overload flow or the phase failure), general service pump quits work, and stand-by pump puts into operation; When stand-by pump fault (overload, overcurrent or the phase failure), stand-by pump works on, and sends sound and light alarm simultaneously.
With reference to Fig. 5, this is the schematic diagram of the secondary circuit power-supply device of fire pump stabilized pressure pump control device of the present invention.
Promptly, draw the control circuit that two power supplys are given general service pump and stand-by pump respectively, to increase the reliability of control system in the end of incoming cables of control power supply.
