Description
One, technical field
The utility model relates to a kind of liquid-cooling type Power Resistor, it is a kind of by PVDF engineering plastics (polyvinylidene fluoride resin) housing, the liquid direct cooling type Power Resistor that spiral water channel and opposite-flushing type resistive band combine is used for superhigh pressure, extra-high voltage direct-current transmission, high-power frequency conversion field.
Two, background technology
Water-cooled resistor domestic, international traditional form is designed to the design of fluid container type and beeline channel formula at present, and its shortcoming is: 1, the liquid flow dead angle is arranged, and liquid can not first in first out, last-in, last-out, and long-term use just can cause liquid electric conductivity higher; 2, the inductance value of resistance was larger after the resistive band banding twined, and was not suitable for high-frequency circuit; 3, the welding of welding rod formula or sealing gasket chip antiseep, its reliability is not high, and anti-fluid pressure is not high; 4, raw material are unskilled labor engineering plastics or nylon, and the proof voltage grade is not high, and poor fire causes life of product greatly to shorten and only is confined to pure water and lowers the temperature.
Three, utility model content
It is fire-retardant, high voltage withstanding that the purpose of this utility model provides a kind of energy, and ageing resistance is strong, can be used for the liquid-cooling type Power Resistor of superhigh pressure, extra-high voltage direct-current transmission, high-power frequency conversion field, ship power system, wind generator system.
The purpose of this utility model is achieved like this: comprising: the shell chassis, outer casing upper cover, binding post, silicone rubber O-ring, parallel packing ring, spring washer, locking nut, symmetrical expression punched resistive band, it is to be 120mm with length, width is that the shell chassis design of 110mm is Archimedian screw formula through type fluid passage, the two ends of symmetrical expression punched resistive band and binding post are welded into one respectively and become resistive element, two ends add that respectively the silicone rubber O-ring hub disk is around being inserted in the middle of the Archimedian screw formula through type fluid passage after its shaping, two ends add parallel packing ring, spring washer, lock by locking nut, again its assembly and outer casing upper cover thermal welding are welded as a whole, and keep weld seam.
Advantage of the present utility model is described below:
1, Archimedian screw formula through type fluid passage design, its advantage is: the no liquid flow blind angle, the liquid first in first out, last-in, last-out, thermal conductivity is high, uses for a long time liquid electric conductivity low; So that the inductance value of resistive element (especially longer resistance body) is cancelled out each other, it is minimum to reach the resistor inductance value to the spiral water channel design of scale.
The fluid passage part of 2 overall plastic shapes and thermal welding welding resistive element, its advantage is: shell chassis and the welding of outer casing upper cover two parts are the same engineering plastics, and firmness is high, so that highly pressurised liquid easy to leak not; Adopt the high grade project fluoroplastics, so that resistance housing proof voltage grade improves greatly.
3 adopt high stability, acid proof fluoroplastics (polyvinylidene fluoride resin) to do housing and be designed to fluid passage, so that the dirt of resistor resistive element after long-term the use can carry out the pickling maintenance, thereby reach the useful life about 50 years.In addition, can use any cooling liquid that comprises pure water.
The utlity model has fire-retardantly, high voltage withstanding, inductance is little, and office puts little, ageing resistance is strong, power is large, high reliability, and externally environment is harsh, high voltage, high-power, to use for a long time under the demanding condition, the scope of application is wider, can be used for superhigh pressure, extra-high voltage direct-current transmission, high-power frequency conversion field, ship power system, wind generator system, be specially adapted in superhigh pressure, the extra-high voltage direct-current transmission converter valve.
