Description of drawings
Fig. 1 is circuit working schematic diagram of the present utility model.
Fig. 2 is the structured flowchart of the whole electric power system of the utility model.
In figure: ZD-DC power supply, SA-manual automatic transfer switch, KM1-electrical network contactor, KA1-demagnetization relay, KM-master switch, M-direct current machine, B-alarm, KA2-latching relay.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
as shown in Figure 1, the utility model comprises DC power supply ZD, manual automatic transfer switch SA, electrical network contactor KM1, demagnetization relay K A1, master switch KM, direct current machine M, alarm B and latching relay KA2, the cathode output end of DC power supply ZD simultaneously and the input of manual automatic transfer switch SA be connected an end with latching relay KA2 coil and be connected, manual automatic transfer switch SA comprises the first output and the second output, the second output is connected with an end of electrical network contactor KM1 contact, the other end of electrical network contactor KM1 contact is connected with an end of demagnetization relay K A1 coil, the other end of demagnetization relay coil KA1 connects and is connected with an end of master switch KM contact, the other end of master switch KM contact is connected with the input of direct current machine M, the output of direct current machine M simultaneously and the negative input of DC power supply ZD be connected an end with alarm B and be connected, the other end of alarm B simultaneously and an end of demagnetization relay K A1 contact be connected an end with latching relay KA2 contact and be connected, the other end of demagnetization relay contact KA1 is connected with the latching relay KA2 coil other end with the other end of latching relay KA2 contact simultaneously.
As shown in Figure 2, the coil of electrical network contactor KM1 is arranged in electrical network, and the normally-closed contact of demagnetization relay K A1 is arranged in field circuit.
Operation principle of the present utility model is: when hydraulic generator worked, manual automatic transfer switch SA1 was placed in automated location.when electrical network and generator disconnect, electrical breakdown, thereby electrical network contactor KM dead electricity, the normally-closed contact of electrical network contactor KM closes, this moment, the DC power supply output current flow through manual automatic transfer switch SA1, then flow through the normally-closed contact of electrical network contactor KM, flow through again the coil of demagnetization relay K A1, thereby the normally opened contact of demagnetization relay K A1 is closed, alarm place in circuit and start to report to the police, the normally-closed contact of demagnetization relay K A1 disconnects, field circuit breaks, because generator need to be connected into field circuit and just can be magnetic, just can produce voltage by cutting the magnetic motion, so this moment loss of exicitation, generator is output voltage no longer.Electric current flows to master switch KM from the coil of demagnetization relay K A1, flow to again direct current machine M, thereby direct current machine starts to rotate the motion of drive reducing gear, make the speed regulator entry into service of the hydraulic turbine, through after a while after the hydraulic turbine stops, master switch KM disconnects, this moment, the whole system of hydraulic generator all decommissioned, due to the existence that latching relay is arranged, so alarm continues warning, until the staff carrys out the processing accident.
