- 產(chǎn)品優(yōu)點
能在保持電機(jī)起動轉(zhuǎn)矩不變的情況下,使起動電流從7Ie降到1.6Ie,并能以最大轉(zhuǎn)矩起動電機(jī)。它由電阻起動裝置發(fā)展而來,具有如下創(chuàng)新點:
1、徹底根除使用滑環(huán)、碳刷時所造成的各種危害。去掉傳統(tǒng)、復(fù)雜的起動裝置,操作方便,并可減少維修費(fèi)用。
2、節(jié)省安裝空間和二次回路電纜,減少起動裝置的功率消耗,節(jié)約了電能。
3、起動控制由起動器根據(jù)電機(jī)的轉(zhuǎn)速自動完成,徹底避免了其它起動裝置不能根據(jù)負(fù)載的大小,自動跟蹤電機(jī)起動過程而造成電機(jī)或起動器損壞等不良現(xiàn)象。
4、電機(jī)運(yùn)轉(zhuǎn)過程中,如出現(xiàn)堵轉(zhuǎn)現(xiàn)象,隨著電機(jī)轉(zhuǎn)速的降低,起動器會自動投入運(yùn)行,達(dá)到增加電機(jī)轉(zhuǎn)矩,減少起動電流的目的。
5、克服了定子控制式電機(jī)軟起動器的起動轉(zhuǎn)矩與起動電流的平方成正比這一缺陷,在降低電機(jī)起動電流的同時,增加電機(jī)起動轉(zhuǎn)矩,并能以最大轉(zhuǎn)矩起動電機(jī),采用無刷運(yùn)行,去掉了傳統(tǒng)、 繁瑣、多觸點元件組成的起動裝置,其起動裝置的功率損耗及電機(jī)的起動時間比定子控制式電機(jī)軟起動器減少10倍以上,但起動器的綜合價格不及其它軟起動器的1/3。
6、起動電阻直接安裝在電動機(jī)的轉(zhuǎn)軸上,利用電機(jī)旋轉(zhuǎn)時產(chǎn)生離心力作為動力,控制電阻的大小,達(dá)到減少電機(jī)起動電流、增加起動轉(zhuǎn)矩,實現(xiàn)無刷自控運(yùn)行的目的。
7、采用防銹、防變質(zhì)、防凍(冰點心-25℃)、防沸(沸點為120 ℃)的四防起動液,提高起動器的使用壽命。
8、設(shè)置安全排氣閥,在電機(jī)轉(zhuǎn)速達(dá)到額定轉(zhuǎn)速后,自動打開排氣閥,保證起動器的安全可靠運(yùn)行。
- ADVANTAGE OF PRODUCTION
The starting current can be reduced from 7le to 1.6le under the condition of keeping the torque unchanged.it can start the motor with largest torque:
1、It is from resistance starting equiment, which has below new characteristics:removing the harm from ring and carbon brush.it saves repairing expense without traditional complex starting equipment.
2、Saving the installation space and secondary loop cable,reducing the power waste of starting equipment, power wasbess.starting control is completed from starter according to the speed of motor.
3、It avoids the phenomena that some damage to motor and starter from other equipment can not trace the starting process of motor by overload.
4、During the process of running, if it appears locked-rotor, the starter will automatically run for the reduction of motor speed to reach the goal of increasing the torque and reducing current of motor.
5、Conquering the default that square of starting current is proportional to torque on stator controlled motor soft-starter with starting current. increasing the motor torque when reducing the current. adopting brushless running, it is 10 times to save the power and starting times.however, the price is not reached 1/3 than other soft-starter.
6、The starting resistance is directly installed the rotoring shaft of motor, using the centrifugal power as driving, control the starting resistance to reduce the starting current, increase torque、 equipping the no brush self -controlled motor to winding asynchronous motor.
7、In order to prolong the using life, adopting the starting liquid to resisting rust、deteroprate、 freeze、boiling(boiling point is120℃).
8、To guarantee running safety, it needs to set the safey exhausting valve, which will be opened automatically when reaching the rated speed
