Problems solved by technology

[0002] Normally, orbital welding machines need their own power supply to work, and the power supply provides three-phase points. Orbital welding machines need single-phase power, so there will be three-phase imbalance problems, which will easily cause power supply equipment to burn out, so it is necessary to The power of power supply equipment is amplified a lot, which will cause problems such as large equipment size, high cost, low reliability, and low work efficiency. With the development of society, in order to improve the reliability of power supply equipment, as well as energy shortage and environmental protection, energy saving Emission reduction needs, need to develop new generator products
At present, there is no way to improve the efficiency of generators, reduce the volume of generators and reduce the consumption of raw materials for manufacturing generators through high-power single-phase winding technology, fundamental wave plus harmonic compound excitation technology, and strong damping technology. High-power track welding high-efficiency excitation single-phase generator

Abstract

A high-power track welding efficient excitation single-phase generator comprises a front end cover, a stator, a rotor, an excitation box, an exciter, a rear end cover, a bearing and supporting frames. The front end cover is connected with the stator, the stator is connected with the rotor through the bearing inside the rear end cover, the exciter is arranged on one side of the stator and the rotor, the excitation box is installed at the upper end of the generator, and the whole generator is supported by the two supporting frames. The high-power track welding efficient excitation single-phase generator has the advantages that the efficiency of the generator is improved, the current shock ability is improved, the size of the generator is reduced, the consumption of raw materials in the process of manufacturing the generator is reduced, the transient response ability is improved, the high-power track welding efficient excitation single-phase generator is especially suitable for being used in track welding machines, and the investment and the use cost can be lowered.

Description

technical field [0001] The invention relates to a generator, in particular to a high-power rail welding high-efficiency excitation single-phase generator. Background technique [0002] Normally, orbital welding machines need their own power supply to work, and the power supply provides three-phase points. Orbital welding machines need single-phase power, so there will be three-phase imbalance problems, which will easily cause power supply equipment to burn out, so it is necessary to The power of power supply equipment is amplified a lot, which will cause problems such as large equipment size, high cost, low reliability, and low work efficiency. With the development of society, in order to improve the reliability of power supply equipment, as well as energy shortage and environmental protection, energy saving To meet the demand for emission reduction, it is necessary to develop new generator products. At present, there is no way to improve the efficiency of generators, reduc...
