Description
Technical field
The present invention relates to resistive technologies field, be specifically related to a kind of high-power high stability resistor.
Background technology
Board-like resistor is mainly used in the starting of elevator, crane, port machine, milling train, hoist engine, generator, frequency converter etc., braking, speed governing and load etc., its requirement has higher resistance stability and higher power, so that the above-mentioned work waiting equipment normal, stable of fast and accurate control.But existing bar resistor device adopts conventional, electric-resistance silk, the unstable properties such as one starting, braking, speed governing and load, cause wear and tear of machinery comparatively large and affect normal work; Its two power is little, cannot solve the electric current of many main equipments, voltage control requirement, narrow application range; Its three substrates heat dispersion is poor, and cause the overall service wear of resistor to increase, useful life is shorter.
Therefore, based on the problems referred to above, the invention provides a kind of high-power high stability resistor.
Summary of the invention
Goal of the invention: object of the present invention provides a kind of high-power high stability resistor, solve existing resistor power large, start and the shortcoming such as braking ability is unstable, heat dispersion is poor, improve and control precision, extend resistor useful life.
Technical scheme: a kind of high-power high stability resistor, comprises stripe board, strip groove, L shape clamp, heat radiation circular hole, the first semicircle ceramic wafer, the second semicircle ceramic wafer and resistance wrapping wire; Described strip groove and L shape clamp are arranged on stripe board two ends; Described heat radiation circular hole is arranged on stripe board inside; Described first semicircle ceramic wafer, the second semicircle ceramic wafer are arranged on stripe board both sides; In described resistance wrapping wire uniform winding and stripe board; Wherein, resistance wrapping wire is constantan or nichrome wire.
The technical program, described stripe board, strip groove, L shape clamp and heat radiation circular hole adopt iron one-body molded obtained, and length is 300mm, width is 100mm.
The technical program, described first semicircle ceramic wafer, the second semicircle ceramic wafer adopt high-temp resisting high-humidity resisting, radioresistance electronic ceramic.
Compared with prior art, the beneficial effect of a kind of high-power high stability resistor of the present invention is: 1, adopt in iron stripe board and arrange circular louvre, the heat produced during work can shed by time, and then ensures the control that resistor is accurate, stable; 2, semicircle ceramic wafer has good insulation property, ensures non-interference between resistance wire; 3, can flexibly with the use of, safe and reliable.Simultaneously structure of the present invention is simple, production cost is low, easily promote.
Accompanying drawing explanation
