Problems solved by technology

[0003] However, the control mode of the existing eddy current retarder is mainly based on the control mode of the relay and also has a small amount of electronic controller. When the contacts are disconnected, it is easy to generate spark ablation contacts, which will increase the damage rate of the relay controller and affect the wor

Abstract

The invention relates to an eddy current retarder electronic controller. The controller is mainly formed by an MCU control unit, a power tube drive unit and a power control unit assembly and the like. The temperature of a retarder is reduced through a water flow control unit, a retarder temperature monitoring unit and a water temperature detection unit, and thus heat fading rate of the retarder is reduced; the output power of the retarder is reduced when the voltage is low through a voltage detection unit, and thus an energy-saving and consumption-reducing effect is achieved; a controller temperature monitoring unit protects a power tube assembly from being damaged by high temperature; and corresponding currents are output to all exciting windings through PWM(pulse width modulation) signals, so that corresponding moment is generated to play a braking role on an advancing automobile.

Description

technical field [0001] The invention relates to a control device of a retarder, in particular to an electronic controller of an electric eddy current retarder. Background technique [0002] The retarder controller is the core component of the retarder, which controls the normal operation of the entire retarder. The thermal decay of the retarder is an important performance index of the retarder. The temperature of the retarder can reach 80°C within 1 minute, and the output torque is reduced by about 15%. The maximum temperature of the excitation coil when the retarder is working within 20 minutes When the temperature reaches 200°C, the output torque will be reduced by 50%. Therefore, how to control the temperature of the retarder is a problem that manufacturers have been exploring. [0003] However, the control mode of the existing eddy current retarder is mainly based on the control mode of the relay and also has a small amount of electronic controller. When the contacts a...
