Abstract

The invention belongs to the resistor technical field, especially discloses a high-power high-stability resistor. The resistor comprises a strip-shaped plate, a strip-shaped groove, an L-shaped clamping plate, heat radiation round holes, a first semicircular ceramic plate, a second semicircular ceramic plate and a resistor wire winding. The high-power high-stability resistor of the invention is advantaged by that 1, in adoption of the round heat radiation holes arranged on the strip-shaped plate, the heat energy generated in working can be radiated timely, the precise and stable control of the resistor is ensured; 2, the semicircular ceramic plates have good insulation performance, therefore, mutual interferences among the resistance wires are eliminated; 3, the resistor can be used flexibly through matching; the use is safe and reliable; and the resistor is featured by simple structure, low production cost and easy popularization.

Description

technical field [0001] The invention relates to the technical field of resistors, in particular to a resistor with high power and high stability. Background technique [0002] Plate resistors are mainly used for starting, braking, speed regulation and load of elevators, cranes, port machinery, rolling mills, hoists, generators, frequency converters, etc., which require high resistance resistance stability and High power, in order to quickly and accurately control the normal and stable work of the above-mentioned equipment. However, the existing strip resistors use ordinary resistance wires. First, the performance of starting, braking, speed regulation, and load is unstable, which leads to large machine losses and affects normal work; second, the power is small and cannot solve the problem of many large equipment Due to the current and voltage control requirements, the scope of application is narrow; the heat dissipation performance of the three substrates is poor, resulting...
