Quantity in order to set up cable between the outlet gate that effectively reduces reservoir and control room in the present invention; Through in the keying room of outlet gate, phase-sequence indicator being set; This phase-sequence indicator comprises: totally four of the ac motors of a three-phase 10, mag-dynamo 11, electronic component commutation diode 18,21,20,19; Electronic component transistor 13 and 14 and AC voltage transformers 12 that no-load voltage ratio is 380V: 12V, motor 10 drive dc generator 11 generatings.
Wherein, motor 10 is connected with A, B, C three-phase alternating current power supply circuits, and motor 10 drives dc generator 11 generatings.Connect forward switch and reverser respectively at dc generator 11; Wherein, Be connected with transistor 13 and transistor 14 respectively at dc generator 11 two ends; The ground level of this concrete transistor 13 and the two ends that colelctor electrode is connected dc generator 11, the ground level of transistor 14 and colelctor electrode are connected the two ends of dc generator 11.Wherein, transistor 13 conductings were opposite when dc generator 11 sent the DC current of anodal negative pole down, when the anodal down DC current of going up negative pole takes place in dc generator 11, and transistor 14 conductings.
In addition; The AC voltage transformer 12 of the base stage of transistor 13 and emitter stage and 380V: 12V is connected; And be serially connected with relay 15 and commutation diode 18 betwixt, the pair of contact 15 of relay 15 is connected in the alternating current circuit of A.C. contactor 17, sensor 6, travel switch 7 formations.The AC voltage transformer 12 of the base stage of transistor 14 and emitter stage and 380V: 12V is connected and is serially connected with relay 16 and commutation diode 19 betwixt, and the pair of contact 16 of relay 16 is connected in the alternating current circuit of A.C. contactor 17, sensor 8, travel switch 9 formations.Three pairs of contacts of other of A.C. contactor 17 are connected in the loop of A, B, C three-phase and motor 1 formation.
The concrete course of work of this phase-sequence indicator comprises in the present invention: when turning to of ac motor 10 changes; The direction of the DC current that dc generator 11 sends also changes simultaneously; The positive pole and the negative pole that are its electric current carry out conversion, thereby the direction that forces transistor 13 or 14 to detect DC current changes, and make relay 15 or 16 adhesives that are connected with this phase-sequence indicator; Thereby promote 15 or 16 corresponding contact conductings; Let A cross streams electricity input travel switch 7 or 9, make A.C. contactor 17 adhesives, realize the Long-distance Control of outlet gate.
Be elaborated in conjunction with circuit connection structure shown in Figure 2 remote control process to outlet gate of the present invention; When needs are opened outlet gate, press rising button 4, make A.C. contactor 2 receive its closing of contact of electricity; For the 10 input three-phases of the motor in the phase-sequence indicator are just changeing electric current; Motor 10 in the phase-sequence indicator is just changeing and is driving dc generator 11 and just changeing, and sends DC current, wherein the direction of DC current according to shown in Figure 2 be negative pole under the last positive pole (shown in Fig. 2+-); Transistor 13 conductings this moment, 14 lead obstructed.
Because transistor 13 conductings through AC voltage transformer 12 power supplies, thereby receive relay 15; Promote its contact 15 adhesives; Make A cross streams electricity through chain contact 15 input travel switches 7 again, make A.C. contactor 17 receive electricity again, make the contact adhesive of A.C. contactor 17; Thereby for motor 1 input three-phase is just changeing electric current, outlet gate begins to rise under the drive of motor 1.
When outlet gate rose to setting high-order, sensor 6 forced travel switch 7 contact separation, thereby A.C. contactor 17 outage backs are separated, and motor 1 stops operating, and reaches the high position that outlet gate is opened to setting.At this moment, because sensor 6 forced travel switch 7 contacts to be in released state, even press rising button 4 again, A.C. contactor 17 also can't adhesive, and motor 1 can not rotate yet, the outlet gate rising of also can not transfiniting.
And, in the uphill process of above-mentioned outlet gate, manually control the stopping of uphill process of outlet gate if desired; Can press stop button 22; Make A.C. contactor 2 outages, make ac power supply line be in off-state, thereby force motor 1 to stop operating.
Concrete, when the lifting height of monitoring outlet gate, comprising: the lifting height of monitoring said outlet gate; The lifting height of the said outlet gate that monitors and the high-value of setting are compared; When the lifting height of the said outlet gate that monitors reaches said high-value, control said valve control motor and open circuit.
When needs are closed outlet gate, press decline button 5, make A.C. contactor 3 energisings; The closing of contact of this A.C. contactor 3 is the 10 input three-phase reverse currents of the motor in the phase-sequence indicator, motor 10 counter-rotatings in the phase-sequence indicator; And drive dc generator 11 counter-rotatings, and send DC current, wherein the direction of DC current is anodal under the last negative pole; Go up the in the opposite direction of anodal negative pole down with shown in Figure 2, transistor 14 conductings this moment, 13 lead obstructed.
Because transistor 14 conductings through AC voltage transformer 12 power supplies, thereby receive relay 16; Promote its contact 16 adhesives; Make A cross streams electricity through chain contact 16 input travel switches 9 again, make A.C. contactor 17 receive electricity again, make the contact adhesive of A.C. contactor 17; Thereby be motor 1 input three-phase reverse current, outlet gate begins to descend under the drive of motor 1.
When outlet gate dropped to the low level of setting, sensor 8 forced the shunting of travel switch 9 contacts, thereby A.C. contactor 17 outage backs are separated, and motor 1 stops operating, and reaches the low level that outlet gate is closed in setting.Because sensor 8 forced travel switch 9 contacts to be in released state, even press decline button 5 again, A.C. contactor 17 can adhesive yet, and motor 1 can not rotate the outlet gate decline of can not transfiniting yet.
And, in the decline process of above-mentioned outlet gate, manually control the stopping of decline process of outlet gate if desired; Can press stop button 23; Make A.C. contactor 3 outages, make ac power supply line be in off-state, thereby force motor 1 to stop operating.
Concrete, when the falling head of monitoring outlet gate, comprising: the falling head of monitoring said outlet gate; The falling head of the said outlet gate that monitors and the low-value of setting are compared; When monitor the falling head of said outlet gate when reaching said low-value, control said valve control motor and open circuit.
