Electric the intersection of generating set and automatic the intersection of voltage stabilizer and circuit that example introduce this, have the intersection of steady voltage and of good performance, have a good adaptability, characteristic such as being with low costs, can be used in various medium and small-scaly and fire automatic steady voltage such as generating set and power station inside, can also be used for transforming the outdated generating set. The automatic voltage stabilizer circuit of this generating set of operation principle of the circuit is touched off the circuit of the power synchronously, relaxation piece shake trigger, the intersection of steady voltage and control circuit, have the intersection of work and electric current it regulates circuit, exterior power to be enough to protect the circuit. Circuit of excitation and filling the magnetic circuit to make up,

Touch off the circuit of the power by the power transformer T synchronously, commutate the diode VD4 to make up VD9, steady voltage diode VS1 and resistor R1. The relaxation one is shaken circuit of the trigger to manage VU, resistor R2 R5 and condenser C2, C3 to make up by the transistor V2, single crystalline solid. The intersection of steady voltage and the intersection of control circuit and T by power transformer, commutate the intersection of diode and VD10 VD15, resistor R6 R8, potentiometer RP2, condenser C1 and steady voltage diode VS2, VS3 make up. There is not electric current of work that regulate the circuit by mutual inductor TA of the electric current, potentiometer RP1, switch S1 and commutate the diode VD16 VDl9 to make up. Excitation windings WE such as circuit G by the alternating current generator of excitation,etc.; The diode VD1, VD2, brilliant floodgate are in charge of often closing the contact K1 to make up 1, fuse box FU1,etc. of VT, K1. Other power is not enough to protect the circuit to be made up VD31, transistor V1, condenser C4 C8 and relay K2 Rl2, diode VD25 by the resistor R9. Filling the magnetic circuit is filled on magnetic button S2, diode VD2O oftenned closing the contact K1 to make up 2, W4 winding of the fuse box FU2 and T of VD24, K1. After three phases from generator G are exchanged the voltage to step down brilliantly by T, produce 30V three-phase sine to exchange the voltage on W7 winding in W5 of T, produce 18V three-phase sine on W1O winding in W8 and exchange the voltage. After VD4 is until stepping down and VS1 steady voltage flowed in VD9 commutating, R1 limit, 15V ladder-shaped wave direct current emerges to press in W5 voltage on W7 winding, as a synchronous power which shakes the trigger of relaxation; Commutate the intersection of W1O and voltage at the winding by VD1O VD15 by W8, R6 and RP2 limit flow, step down and C1 strain behind the wave, measure the circuit to add and shake the trigger to the relaxation one through the bridge type composed of R7, R8, VS2, VS3, as its voltage of control signal. When the generator G just began to generate electricity, the voltage of C both ends bridge type measure the input voltage of the circuit Relatively low, VS2 and VS3 do not lead openly, the relaxation one shakes the trigger and does not work. When the end voltage of the generator G rises to 200V, VS2 and VS3 puncture and lead openly, makes the relaxation one shake the trigger and work, output the wave signal of the pulse from the first base of VU, this signal is added to the door of VT very much by VD3, touch off signals as it. In this way, set up the voltage of empty load within short time with generator. With the constant rising of the generator end voltage, the voltage of a, b both ends drops gradually. When the end voltage of the generator exceeds 40OV, the voltage of a, b both ends is lowered to OV, make V2 end, the relaxation one shakes the trigger and stops shaking, VU does not have pulse signal that is exported, VT ends, has cut off the direct current source of the circuit of excitation, it is 400V the specified value of empty load to stablize end voltage of the generator . While making the voltage of output end of the generator drop because of load or others, the voltage of a, b both ends will rise immediately, make V2 lead openly, the relaxation one shakes the trigger and shakes the job, pulse signal that VU output VT touch off, lead coherent, strengthen the intersection of generator and excitation electric current of rotor, force the generator output voltage to rise to the specified load voltage value. When the generator runs in parallel, the ones that flow through mutual inductor TA of electric current have no electric current of work to strengthen, make the reaction voltage on TA winding two times rise, this voltage is shunted regulation and VD16 after VD19 commutate by RP1, form the direct current on R6 and press to drop, thus change the level of the voltage of a, b both ends. When there is no electric current of work to increasing, a, the intersection of b and the intersection of both ends and voltage drop, enable leading put through cornering to diminish of VT, the the generator one has no electric current of work to reduce. Act as the other power of the generator internal-combustion engine, hydraulic turbine,etc. When rotational speed insufficient, the intersection of generator and the intersection of output and frequency of voltage will reduce obviously, this will make generator and support Job electric current rise,drop generator end voltage but strengthen to make floodgates brilliant not in charge of VT’s lasting electric current to damaged excitation electric current, even may burn out generator. In order to make the generator stop generating electricity when other power is insufficient, it is not enough to protect the circuit to increase the other power composed of V1 and K2,etc.. When the frequency of the generator output voltage is insufficient because of other power and reduces, it is coherent for V1 to lead, make K2 energize, suck, shut, it turn on contact, put through often, short out VS1, relaxation piece shake trigger, lose the intersection of 15V and voltage and quit work, the brilliant floodgate is in charge of VT and lose and touch off the pulse and end, thus it is in charge of VT to protect generator He Jing floodgate. After the generator G operates, are had the single-phase low voltage about 12V that the magnetic induction forms left Form the direct electric current and flow through the excitation winding WE by VD1 halfwave rectifier, this faint excitation electric current makes the generator stator send out a little higher low-voltage. If the generator rotational speed has already reached the specified value, this regenerative course makes the generator during extremely short time Set up the three-phase end voltage of empty load. When the generator voltage rises to 200~300V, K1 energizes and sucks shutting, it often closes the contact K1-1 and K1-2 disconnection, change, lead by VT coherent to supply excitation electric current. The generator G, while taking load to run under the specified rotational speed, its electric current return circuit of excitation is: Neutral line N Excitation winding WE The brilliant floodgate is in charge of VT Fuse box FU1 U output end of the generator L1 looks . VD2 diode in order to flow continuously, and it connects at excitation winding WE both ends, ends when it is open to lead in VT, it is open to lead when VT ends. Shut down for a long time as generator when being normal cause and lose the magnetism with other reason of making moist etc. seriously, the generator remanence voltage is about 20V, are lost the magnetism, lowered to 6~10V ,Can’t set up the voltage of empty load by oneself. At this moment can press, fill magnetic the intersection of button and S2, lose the intersection of 6~1OV and voltage behind the magnetism, supply excitation coil WE directly after W4 winding stepping up, VD2O of T is until VD24 commutate, make the generator set up the voltage of empty load under losing the magnetic situation, but needn’t connect the storage battery. RP2 locks the potentiometer for the voltage, after the generator is started to run, adjust the hindering value of RP2, make the output voltage of the generator 400V 50Hz or 60Hz .
