Product Description
When the charge moves in the conductor, it will be collided and rubbed by other particles such as molecules and atoms. The result of collision and friction forms the obstruction of the conductor to the current. The most obvious feature of this obstruction is that the conductor consumes electric energy and generates heat (or emits light). This blocking effect of an object on the current is called the resistance of the object. Resistor is generally called resistance directly in daily life. It is a current limiting element. After the resistor is connected in the circuit, the resistance value of the resistor is fixed. Generally, it is two pins, which can limit the current through the branch connected to it. A resistor whose resistance cannot be changed is called a fixed resistor. Those with variable resistance are called potentiometers or variable resistors. The ideal resistor is linear, that is, the instantaneous current passing through the resistor is directly proportional to the applied instantaneous voltage. Variable resistor for voltage division. One or two movable metal contacts are tightly pressed on the exposed resistor. The contact position determines the resistance between either end of the resistor and the contact.
The terminal voltage has a definite functional relationship with the current, which reflects the ability of converting electric energy into other forms. It is represented by the letter R, and the unit is Ohm Ω. Actual devices such as bulbs, heating wires and resistors can be expressed as resistor elements.
The resistance value of the resistance element is generally related to the temperature, material, length and cross-sectional area. The physical quantity measuring the influence of the resistance by the temperature is the temperature coefficient, which is defined as the percentage of the change in the resistance value when the temperature rises by 1 ºC. The main physical feature of resistance is to change electric energy into heat energy. It can also be said that it is an energy consuming element, and the current passes through it to produce internal energy. Resistance usually plays the role of voltage division and shunt in the circuit. For signals, both AC and DC signals can pass through resistors.

Detail of Goods: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 resistanceMain 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 networkKey words : resistor ; brake resistor ; Mitsubishi
