The control cabinet is provided with an Ethernet router, a PLC programmable logic controller and a transformer. The main switch is connected to a tested generator set through a power cable, and the transformer transforms a 380V power into a 220V power and uniformly supplies power to the electric female header or other control devices. The PLC programmable logic controller is provided with an RS232 serial port, and can wirelessly communicate with the main switch and/or a monitoring notebook computer through the Ethernet router. The utility model is characterized by wide loading scope and being able to realize networking operation for a plurality of loads, which satisfying the experimental requirements of large load.
Description
Technical field
The utility model relates to the generating of ocean platform, sea transport ship and the test equipment of electricity generation system.
Background technology
At present, marine vessel load of electrical generation test majority is also used the water resistance mode, and there is tangible deficiency in this mode, at first is precision and less stable, next troublesome poeration, and labour intensity is big.Though the dry type load is arranged now, operation also is in panel hand switch mode, and its complex structure is operated originally, can not be fit to operated from a distance.Along with improving constantly of testing requirements, some complexity, senior load test just are difficult to realize; Automatically the intelligent degree of loading and data processing is low in addition, causes test report to finish by hand.Because the development of network technology and computer monitoring technology, finishing complicated load calculation and measuring and control the reactance of plus-minus resistance by PLC becomes possibility, has so both saved many on-off elements, makes structure simple and clear, also makes operation interface become fine.By network technology, the networking operation of a plurality of load test device, make the prestowage scope broad more, satisfied the requirement of bulk loads test.Computing machine not only can be finished load calculation automatically, and can realize automatically simultaneously can also finishing data storage by prediction scheme or the artificial default off-load that adds, and draws analytic curve and generates test report automatically.
Summary of the invention
Proposition of the present utility model is intended to overcome manual drawback, and integrated use network technology and computer monitoring technology design a kind of intelligent electric power test load system.
Technical solution of the present utility model is achieved in that
