升降機(jī)廠家http://www.it616.com.cn/介紹制動(dòng)電阻能夠?qū)㈦姍C(jī)的產(chǎn)生的多余電能通過(guò)熱能的方式進(jìn)行消耗，這樣一個(gè)載體包括電阻值和功率容量?jī)蓚€(gè)數(shù)值，可選的電阻十分多，而最被常用的是鋁合金和波紋電阻，這兩種電阻分別有各自的特點(diǎn)。
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.
升降機(jī)廠家談到鋁合金電阻外形美觀，散熱強(qiáng)，可附加散熱器，安裝精密，鋁合金外殼全包封閉結(jié)構(gòu)，耐震性極強(qiáng)，不因溫差而改變特性，具有較高的穩(wěn)定性，體積小，功率大，安裝堅(jiān)固便捷，十分適合惡劣環(huán)境下的工作。波紋電阻立式波紋有助于散熱，減輕寄生電感，高阻燃無(wú)機(jī)涂層能夠保護(hù)電阻絲，能延長(zhǎng)電阻絲使用壽命，保護(hù)電阻絲不被老化。
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.
升降機(jī)廠家http://www.it616.com.cn/提醒升降機(jī)設(shè)備在下降時(shí)，會(huì)產(chǎn)生一種慣性使電機(jī)變成發(fā)電機(jī)，這時(shí)會(huì)產(chǎn)生一種電能，該電能將直接施加到變頻器的模塊上，這種情況是十分危險(xiǎn)的，必須及時(shí)處理掉電機(jī)產(chǎn)生的這部分電能，如果不能及時(shí)處理掉，變頻器模塊將受到一定程度的損害，嚴(yán)重時(shí)可直接使變頻器報(bào)廢。加上制動(dòng)電阻，就能將電機(jī)產(chǎn)生的多余電能消耗掉，從而能夠保證變頻器運(yùn)行的穩(wěn)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.
