Description
Technical field
The utility model relates to ship deck mechanical field, especially relates to a kind of frequency conversion system brake resistance.
Background technology
At present, the use of frequency conversion system is very general at shipbuilding industry.China is also studying and is making marine anchor winch and the mooring winch of frequency conversion drive, but often the electric component of frequency conversion system is generally need from external import, therefore, exists from the very high situation of the price of the electric components of external import.Therefore make the marine anchor winch of frequency conversion drive and mooring winch competitive advantage commercially not obvious, especially price advantage.Meanwhile, traditional braking resistor also also exists in actual applications and overall iron aluminium manufacture by cast iron or iron and form, and capacity is little, and useful life is short, easy fracture, and the problem such as Heavy Weight, cost are high, leading-out terminal set-up mode is unreliable, heat dispersion is poor.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and a kind of frequency conversion system brake resistance is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of frequency conversion system brake resistance, comprise casing and resistance, resistance is arranged in casing, described casing is cube, comprise a positive cover plate, a back shroud, biside plate, a top board and a base plate, described resistance, for organize resistor disc more, is often organized resistor disc two ends and is fixed with biside plate respectively, described resistor disc is high-resistance alloy resistance, and described casing is provided with water tight packing and contains.
Described casing is cold-rolled steel sheet, surface plastic spraying process.
The thickness of described positive cover plate is 1mm.
Described positive cover plate is spliced by upper cover plate and lower cover, and the line of demarcation place between described lower cover and lower cover is screwed.
Described positive cover plate, side plate and base plate are equipped with louvre.
Louvre on described positive cover plate and side plate is shutter arranged in parallel, and the louvre on described base plate is netted.
The thickness of described back shroud is 1mm.
Described back shroud is fixedly mounted by screw and metope.
The thickness of described side plate is 2mm.
Compared with prior art, the utility model has the following advantages:
1) the utility model is installed together by casing and resistance, lower cover and lower cover are conducive to segment type assembling and are connected, make it can be contained by water tight packing and the frequency converter selected be interconnected, thus reach the speed that stepless time adjustment controls the landing of anchor winch, what make anchor winch is simple to operation, very clear;
2) the utility model adopts cold-rolled steel sheet, surface plastic spraying process, and thickness is more accurate, and smooth surface, beautiful, also has various superior mechanical performance, particularly processing characteristics aspect simultaneously;
3) the utility model is provided with louvre, and the netted louvre of the shutter and base plate that are arranged at positive cover plate and side plate place is conducive to further distribute heat;
4) the utility model structure is simple, easy to use, performance is comparatively stable, cost is relatively cheap, the purchase cost of frequency conversion system can be reduced, the anchor winch of frequency conversion drive and the cost of manufacture of mooring winch so just can be made to reduce, so that the anchor winch of frequency conversion drive and mooring winch can have lower price advantage in market competition.
