Abstract
The utility model discloses a three phase generation and DC electric welding machine, which is composed of a conventional generator set, a three phase rectifier, and a series-parallel transition device. The utility model is characterized in that an electrical welding winding and an original electricity generation winding has a common winding; a plurality of taps extracted from the electricity generation winding are respectively connected to the input terminal of the series-parallel transition device; the welding current can be regulated. The utility model simplifies the structure of the stator winding of a generation and electric welding machine, and the utility model can meet the requirements of low voltage and high current DC welding by only using a pair of winding arranged on the original electricity generation device.
Description
The utility model belongs to a kind of electric power generation equipment, also is a kind of welding set simultaneously.
Generating, the most structures of the dual-purpose machine of electric welding are that independently electric welding winding is set in the stator of motor.People such as the Qiu Pei of University of Fuzhou base are in that " exemplary configuration of having narrated this dual-purpose machine " used general two-phase symmetrical component method and analyze threephase generator and the dual-purpose machine of electric welding " in the article delivered of 92 year fifth phase " middle and small motor " magazine; this dual-purpose machine is a kind of A.C. welder; all be to increase independently electric welding winding on former three-phase alternating current generating winding; for the harmonic excitation unit; stator coil is four kinds of windings, complex structure, big, the high material consumption of design difficulty nearly, and welding performance is also undesirable.
The utility model purpose is to provide the most succinct a kind of structural design, and big electric current three-phase generation, the dual-purpose machine of direct-current electric welding that is easy to adjust can be provided.
Realize the object of the invention in the following manner.
The utility model includes conventional generator, and all are formed, and the frame and the casing of band stator wherein arranged, and the rotor with excitation winding is for the self-aligning bearing of armature spindle rotation.Also have three-phase rectifier and a three-phase connection in series-parallel control device in addition.Every winding symmetry of generating electricity mutually in the stator has a plurality of taps, is connected, welds winding and the shared one pair of coil of generating winding with three-phase connection in series-parallel control device input respectively.
The dual-purpose machine of the utility model utilizes former generator three phase windings, adopts step-down in parallel, can obtain big welding current.Simple for structure, make dual-purpose machine welding performance reach the welding machine special standard, be specially adapted to power-shortage area or open-air electric welding field.
Accompanying drawing 1 is the utility model stator winding schematic diagram;
Accompanying drawing 2 is the phase structure schematic diagram among the three-phase connection in series-parallel control device K;
TF is a generator in the accompanying drawing 1, and A, B, C are generator unit stator winding output, and N is the star-star connection neutral point, and L1 L2 is an excitation winding; S1-S2 is humorous wave winding, and 1-8 is each phase tap group in the generator windings.
K is a three-phase connection in series-parallel control device in the accompanying drawing 2, and Z is a three-phase rectifier, 1-8 respectively with each connection in series-parallel control input end of connecting of tap mutually; V1 V2 is the electric welding output.
The utility model has compared with prior art been saved an additional electric welding winding, saves noble metal, reduces cost, simplified design and lead time, improves iron overall utilization and welder performance.
