Introduction of Shanghai Marathon Alternator Used in Diesel Generator

Usually, alternator is used in many fields, such as lifting equipment, industrial equipment, and electrical equipment, etc. Alternators are also divided into many brands. Famous one is Siemens, and Stamford. In this article, we mainly talks about Shanghai Marathon alternator . Shanghai Marathon innovative Electric Co.,Ltd.introduces the design and manufacturing process technology of the Marathon Electric U.S.A so as to produce x the international advanced level of single/three-phase brush-less ac generator, with the generator voltage ranging from 110v to 110v and the capacity ranging from 5 kw to 3000 kw.The products are widely used in ordinary power supply, emergency power and special power supply, and they act as the main power supply or emergency power supply in railway, mining, hospital, house property, military industry,ships, reefer container, telecommunications, port machinery and key national projects. MP series 500 frame three-phase brushless ac synchronous g...

Marathon Generator Paralleling Operation And Troubleshooting

VII. Paralleling operation (wiring refer to the appendix): MX generators are suitable for paralleling as full damping winding. But, before paralleling, each unit of generator should be started up, operated and adjusted. A. Base conditions of paralleling operations: 1 . Additional paralleling circuitry a. Voltage regulator-paralleling provisions b. Paralleling current transformer(s) c. Paralleling provisions on governor controls d. Switch gear 2. The voltage and frequency must be the same for all sets with voltages in phase. 3. The generators must have the same phase sequence rotation. 4. The voltage regulation characteristics of the individual generators should be similar. 5. The driving engines should have the same speed regulation characteristics and the governors should be adjusted to give the same speed regulation. B: Reactive load control and adjustment: When two identical generators are operating together in parallel and an unbalance occurs in fiel...

Operation And Maintenance of Marathon MX Series Generator

What do you know about Marathon MX Series three phase AC synchronous brushless generator? In the previous article, we have talked about the general information and installation of the generator. In this post, you will learn the inspection, operation and maintenance of Marathon MX Series 3 phase alternator. V. Inspection and operation 1. Inspection: a. Though the generator, AVR and auxiliary devices are solid and well insulated, if the generator was stored for longtime, it might be moistened or failed and should be inspected carefully before operation. b. Measure the insulating resistance of windings against the ground by megohm-meter, if the value is less than 2 MΩ in cold condition, the generator should be dried. Caution: At measuring, the electronicelements and capacitor should be short circuit, and the AVR should be disconnected to avoid damage. c. Make sure all connecting joints are tight and connected well. d. Be sure the frame is properly grounded, and ground...
