Energy Consumption Dynamic Braking Resistance Box Elevator Parts
Product application:
Suitabil for high-power,high current braking equipment,measure and
test equipment,elevator,harbour machinery,lifting power
brakecircuits of inverter etc...
Description of products:
BRB series braking resistor unit is used for motors in the slow
process of renewable energy, in the form of energy consumption on
the braking resistor, a inverter braking performance and shorten
the inverter braking time.Mainly used in the converter drag system
requires a sharp slowdown, brakes, positioning, etc;Inverter in the
slowdown, due to the drag system of large inertia, the motor is in
a state of power generation, mechanical energy rapid feedback to
the dc bus, make dc bus voltage rise rapidly, so as to endanger the
safety of the inverter, so the feedback energy must be consumed
quickly, keep the dc bus voltage under a safe range, otherwise the
inverter will overvoltage protection or malfunction.Generally large
inertia, or need a sharp slowdown, the situation can use the brake
unit.
Technical features:
1. Big power,small volume, strong-overload,shockproof abilityis
strong,Low temperature rise
Small resistance rate;
2. Wide voltage range, Suitable for all kinds of voltage level of
inverter, the voltage is adjustable continuously from DC250V to
1140V, Permissible to be used at places big grid change;
3. The design was correct , Selection of high-quality components,
Plenty of hot redundancy guarantee, electromagnetic compatibility
is complete, Suitable for harsh industrial environments. Have good
human-machine interface, with simple and convenient operation.
4. The customer can be set up according to the mechanical
characteristics of different and more suitable operation parameters
and the startup mode, bus voltage and the running state of
real-time display;
5. H ave perfect protection function(With short circuit, under
voltage, overvoltage, over current, overheating, etc;
6. Structure of the firm, Strong vibration resistance, Easy to
maintain.
7. long time operation, Winding resistance paint surface.
8. Original resistance diversification, winding resistance,
Aluminum shell resistance, metal tube resistance, metal tube
resistance Original high-power resistance are optional.
