Poznámky redaktora
The financial consequences are considerable; every technical problem and every breakdown costs money terms repairs as well lost production. With ABB Softstar­ ters, possible start and stop smoothly while keeping mechanical and electrical stresses minimum. softstarter the other hand will provide far better performance during the start and also the possibility to soft stop the motor. • Mechanical problems that address the entire drive chain, from motor driven equipment, causing big need for service and repair well unwanted down time. Motor voltage Motor current Torque Graphs showing the basic differences between direct-on-line starting (DOL), star-delta starting and soft starting terms the motor voltage (V), motor current (I) and motor torque (T). • Operational problems, such damage products on conveyor belts. addition, does not provide any way perform a soft stop. One traditional way avoid this use star delta starter. ABB has been producing softstarters since the beginning of the 1980’s. Such transients may overload the local supply network and cause unacceptable voltage variations that interfere with other electrical equipment connected the network. The solution both mechanical and electrical problems AC motors, “the workhorse the industry”, are used drive fans, crushers, agitators, pumps, conveyors, etc. Depending on how installed, too often unnecessary and unwanted torque and current peaks are everyday reality produc­ tion plants all over the world, causing damage several ways. • Water hammering and pressure surges pipe systems when starting and stopping pumps. Among them are: • Electrical problems due voltage and current transients arising from Direct-On-Line Star-Delta starts. Matching modern power electronics with smart circuitry and software, the ABB softstarters offer superior control the current and voltage during motor start-up and stop, addition to several state the art design features.Softstarters From the moment the first electrical motors was developed, engineers have been searching for way avoid electrical and mechanical problems that usually occur when starting the motor. The valuable experience gained since the early 80’s has been incorporated into the design today’s product ran­ ges. 4 Softstarters 1SFC132005C0201 . These problems include high inrush current and current spikes well excessive mechanical wear. This starting method many applications insufficient, as problems with current spikes and torque peaks will remain. The easy solution all these problems install ABB Softstarter type PSR, PSS, PSE PST(B)
