升降机厂家谈制动电阻的作用

升降机厂家http://www.jntr168.com/介绍制动电阻能够将电机的产生的多余电能通过热能的方式进行消耗，这样一个载体包括电阻值和功率容量两个数值，可选的电阻十分多，而最被常用的是铝合金和波纹电阻，这两种电阻分别有各自的特点。
Elevator manufacturers introduced the braking resistor can be excess power generated by the motor thermal energy consumption manner, such a vector comprises a resistance and power capacity of two values, optional resistance very much,but the most commonly used is aluminum and ripple resistor, both resistors have their own characteristics, respectively.

升降机厂家谈到铝合金电阻外形美观，散热强，可附加散热器，安装精密，铝合金外壳全包封闭结构，耐震性极强，不因温差而改变特性，具有较高的稳定性，体积小，功率大，安装坚固便捷，十分适合恶劣环境下的工作。波纹电阻立式波纹有助于散热，减轻寄生电感，高阻燃无机涂层能够保护电阻丝，能延长电阻丝使用寿命，保护电阻丝不被老化。
Lift manufacturers appearance spoke aluminum resistance, heat, and can be attached heat sink, install sophisticated, all-aluminum shell package enclosed structure, strong shock resistance, not due to temperature change characteristics,high stability, small size , power, robust and convenient installation, is very suitable for working in harsh environments. Corrugated vertical corrugation help dissipate heat resistance, reduce parasitic inductance, high fire-retardant inorganic coatings to protect resistance wire, resistance wire can prolong life, protect the resistance wire is not aging.

升降机厂家http://www.jntr168.com/提醒升降机设备在下降时，会产生一种惯性使电机变成发电机，这时会产生一种电能，该电能将直接施加到变频器的模块上，这种情况是十分危险的，必须及时处理掉电机产生的这部分电能，如果不能及时处理掉，变频器模块将受到一定程度的损害，严重时可直接使变频器报废。加上制动电阻，就能将电机产生的多余电能消耗掉，从而能够保证变频器运行的稳定和性能安全。
Lifts lift equipment manufacturers reminded when dropped, will produce a kind of inertia of the motor becomes a generator, then it will produce a electrical energy, which will be applied directly to the inverter module, this situation is very dangerous, and must promptly dispose of this part of the electricity generated by the motor, if not promptly disposed of, the drive module will be a certain degree of damage, severe cases can be directly inverter scrapped. Plus the braking resistor, the excess electricity generated by the motor can be consumed, which can ensure a stable and safe performance of the inverter operation.
