Purpose of the development: Softstarter SMP designed to alternately soft unstressed start of synchronous and asynchronous motors, fan mechanisms of burden

Recommended application field: Energy. Mechanical Engineering. Chemical and cement industries.

Technical characteristic: Specifications SMP: Rated data: - Rated voltage - 3, 6, 10 kV; - Rated current of the main circuit - 70, 150, 200, 400, 630, 800, 1100 A; - The number of feeder loads - determined by the number of engines running; SMP provides alternate soft automatic start and turn to podsinhronnoy speed fan motor mechanisms of burden. Start engine should be in the lowest level of load and moment of resistance is not greater than 0.4 * Mnom., While ensuring: - Limiting inrush current motor at a given level in the range Ip = (1.5 ... 3) Ir.; - Improving durability of the engine due to a significant reduce electrodynamic forces in the motor windings when rockets; - Improving durability switchgear; - Reducing load on the electrical network when starting large motors. There are modifications of the NSR for various currents, voltages, and the number of engines. With the implementation of the SMP can start several groups of motors, each powered by its high-voltage section. SMP provides alternate start and acceleration engines to podsinhronnoy speed with high trigger TLU. Connection of the motor to start is automatic switching device (contactor, switch) corresponding cabinet SHVK.

Advantages over analogues: Soft starting motors powerful compressors, pumps, etc. using SMP reduces adverse events specific to direct starting. Particularly attractive for the selective use of SMP alternate starting several motors. For example, using a sample starter compressor unit compressor station can be provided step control performance of the entire plant. Softstarter SMP equally suitable for start-up as asynchronous and synchronous motor, in which case the use of SMP starts the motor field.

The development stage readiness: Ready for application

Description of the development:
()
The structure of the SMP include: 1. High-voltage starter (SPM); 2. Switchgear cells - by the number of high-sections; 3. Contactor cabinets - the number of lines by the number of load start the engine; 4. Cabinets breakers (for safe handling CPG); 5. Thyristor exciters (for synchronous motors); 6. The control cabinet. 7. Accessories.
