Technical field
The utility model relates to the converter cable of a kind of waterproof oil resistant dirt, relates to or rather the dirty 10kV medium voltage frequency converter of a kind of waterproof oil resistant cable.Belong to field of cables.
Background technology
Along with the development of electric power, electronic technology and microelectric technique, ac variable speed technology is developed rapidly and is day by day perfect, and the low-voltage variable frequency speed adjusting technique of Small And Medium Capacity has been widely used in industrial production and daily life.In recent years, increase and pour in the domestic market rapidly along with external frequency converter markets, being on the increase of centering, high-voltage large-capacity alternating current machine demand, although the importance of frequency converter is more and more paid close attention to by people, but the middle high-pressure converter technique still belongs to a new technology at home, the middle high-pressure frequency converter of selection in domestic depends on import mostly, and is connected the middle high-pressure converter cable of transmission with power supply and motor as frequency converter, is also mostly provided together by offshore company.
In industrial circle, the 10kV Medium-voltage motor adopts the more and more of frequency control at present, and 10kV medium voltage frequency converter cable is the stube cable of frequency converter and power supply, when working due to frequency conversion speed-adjusting system, frequency translation is more frequent, thereby can electric power realize the work quality of frequency converter after by cable transmission, and the performance characteristics of cable itself is most important.
from whole frequency conversion system, cable will adapt to this requirement, must fully guarantee aspect two: the one, the construction of cable, at first the construction of cable should satisfy the frequency converter input mode, for present frequency converter development trend and performance need, must be designed to " 3+3 " structure or concentric conductor structure, there is producer once to attempt common cable is used for the input and output system of frequency converter, but after using, misoperation often appears in system, can't work, " 3+3 " structure or concentric conductor structure can effectively realize the coupling of frequency converter and power supply, improve power factor, reduce the harmful effect of input high order harmonic component.The 2nd, cable should satisfy EMC Requirements, not only will accomplish to prevent external electromagnetic field to the impact of cable, accomplishes again to prevent cable itself to the impact of other components and parts of frequency converter, and this just proposes higher requirement to cable shield, accomplishes accurate design.
Converter cable is applicable to drive system, be particularly useful for the applications such as papermaking, iron and steel, weaving, metal processing and food processing, such cable is laid in usually that greasy dirt is heavy, moist gas large, have in the abominable operational environment such as ponding, when cable be in for a long time moist gas large, ponding arranged, contain when working in the adverse circumstances of oils, cable should have certain waterproof and suppress the ability of oils infiltration, and the cable that only depends on common shielding layer structure is obviously to meet this requirement.
As everyone knows, frequency converter not only is used widely in traditional drive system, and almost expanded to industrial all spectra, this is the certainty of development in science and technology, growth rate every year of recent domestic frequency converter markets is all more than 10%, due to the remarkable advantage of frequency converter at aspects such as energy-conservation, performance, efficient, operability, the application of frequency converter has further and enlarges.For the present situation of converter cable, problem and the specific operational environment of existence, the utility model intends providing the dirty 10kV medium voltage frequency converter of a kind of waterproof oil resistant cable, to satisfy ever-increasing domestic and international market demand, reduce simultaneously the dependence to the import converter cable.The dirty 10kV medium voltage frequency converter of the waterproof oil resistant of developing cable, have excellent high electrical performance, the construction of cable and Electro Magnetic Compatibility, simultaneously cable can adapt to that greasy dirt is heavy, moist gas is large, the abominable operational environment such as ponding is arranged, for the application of widening cable product, meet the need of market, all tool is of great significance.
