Function of braking resistance: 1 Protect the frequency converter; 2. Protect the power network. Braking resistance is a kind of ripple resistance, which is mainly used in the mechanical system of frequency converter controlling the rapid shutdown of motor. The firecracker motor converts the regenerative electric energy generated by the rapid shutdown into heat energy. The principle of resistance braking is that the rotor has current flow, which generates torque opposite to the rotation direction in the magnetic field of the stator, consumes the kinetic energy of the train, and achieves the purpose of braking. When the motor or other inductive load driven by the frequency converter stops, it is generally realized by energy consumption braking, that is, the kinetic energy of the motor and the magnetic energy in the coil are consumed through another energy consuming element after stopping, so as to realize rapid shutdown.
Compent:
Ceramic tube: it is the skeleton of alloy resistance wire and has the effect of radiator at the same time


Alloy resistance wire: the flat belt has a wavy shape and is wound on the surface of the ceramic tube, which is responsible for converting the regenerated electric energy of the motor into heat energy


The coating is flame-retardant on the surface of the alloy and has the characteristics of high temperature resistance
Main hazards
During the rapid shutdown of the motor, a large amount of regenerative electric energy will be generated due to inertia. If this part of regenerative electric energy is not consumed in time, it will directly act on the DC circuit part of the frequency converter. If it is light, the frequency converter will report fault, and if it is serious, the frequency converter will be damaged; The emergence of braking resistance solves this problem and protects the frequency converter from the harm of motor regenerative electric energy;
Smooth operation
The braking resistance directly converts the regenerative electric energy in the process of rapid braking of the motor into heat energy, so that the regenerative electric energy will not be fed back to the power network and will not cause grid voltage fluctuation, which plays a role in ensuring the smooth operation of the power network
