Description
Technical field
The present invention relates to a kind of generator, relate in particular to the efficient excitation single-phase generator of a kind of high-power track welding.
Background technology
Generally; orbital welder all needs power autonomous work; and power supply is all to provide triple point; orbital welder needs single-phase electricity; so can there is three-phase imbalance problem; easily cause power-supply device to burn out; therefore need to power-supply device power amplification is a lot; can produce like this problems such as equipment volume is large, cost is high, reliability is low, inefficiency; along with social development; in order to improve the reliability of power-supply device, and the energy-saving and emission-reduction demand of the protection of the in short supply and environment of the energy, new generator product need to be developed.Not yet find by high-power single-phase winding technology in the market, first-harmonic adds the efficiency that harmonic wave compound rectifier excitation technology, heavy damping technology etc. have improved generator, dwindles the volume of generator and reduces and manufacture generator to the efficient excitation single-phase generator of a kind of high-power track welding of raw-material consumption.
Summary of the invention
The object of the present invention is to provide the efficient excitation single-phase generator of a kind of high-power track welding, this generator adopts the high-power single-phase no-brush synchronous generator of field spider structure, it has improved the efficiency of generator, dwindles the volume of generator and reduces and manufacture generator to raw-material consumption.

Embodiment
As shown in Figure 1, the present invention comes work and enforcement like this, it comprises front end housing 1, stator 2, rotor 3, excitation box 4, exciter 5, rear end cap 6, bearing 7 and bracing frame 8, it is characterized in that: front end housing 1 is connected with stator 2, stator 2 is used for fixing stator core, stator 2 is connected with the bearing 7 of rotor 3 by rear end cap 6, rotor 3 is in stator 2 inner chamber runnings, exciter 5 is in a side of stator 2 and rotor 3, for rotor field winding provides magnetization energy, frequency is 50HZ, rated power is 400kW, rated voltage 400V, rated power factor is 0.8, stator slot is 60 grooves, excitation box 4 is arranged on generator upper end, whole generator supports with two bracing frames 8.In stator 2, stator core is embedded with the auxiliary winding of high-power single-phase winding, triple-frequency harmonics winding and first-harmonic.Rotor 3 rotor iron cores are whole salient pole punching 4 electrode structures, and rotor winding is centralized winding, and rotor 3 adopts heavy damping structure.
As shown in Figure 2, after generator starting, rely on the remanent magnetism voltage of generator, after rectification, to exciter excitation winding h, provide exciting current, armature of exciter winding g voltage raises gradually, and this alternating voltage is sent into main frame excitation winding d after rotary rectifier module f rectification, make single-phase stator winding a set up voltage, when rotating speed approaches rated value, SY-AVR-3053 rises rapidly generator voltage, and is stabilized in rated value.Generator is in normal course of operation, when terminal voltage has the trend of reduction, SY-AVR-3053 can detect this small voltage deviation, and promptly increase the electric current of the auxiliary winding c of harmonic winding b, first-harmonic, increase the exciting current that offers exciter excitation winding h, supplement the energy of main frame excitation winding d, single-phase stator winding a voltage is raise, the terminal voltage that maintains generator is approximate constant.When generator voltage has the trend of rising; be and the electric current of the auxiliary winding c of harmonic reduction winding b, first-harmonic promptly; reduce to offer the exciting current of exciter excitation winding h; reduce the energy of main frame excitation winding d; make single-phase stator winding a lower voltage; the terminal voltage that maintains generator is approximate constant, damages rotary rectifier module f when piezo-resistance e is used for preventing overtension, and then the supplementary main frame excitation winding d of protection can not damage.
