High-voltage soft starter SAMSON



Main parameters

  • Rated load current in standard working conditions 80А, 159А, 230А, 321А.;

  • Rated voltage (line voltage) 6 и 10 кВ;

  • Motor capacity from 280 to 3600 kW

Description

High-voltage soft starter of domestic production SAMSON is meant for asynchronous and synchronous motor of power capacity from 280 to 3600 kW and voltage of 2,3 kV to 7,2 kVcontrol. This device provides the function of the soft start, which decreases the starter current from 5-7 multiple unnormalized value during the direct start to target normalized value.
Starting current ration can be programmed in the range of 1-6 during equipment adjustment (default multiplicity is equal to 4, is majority of cases during the commissioning is set in the range of 3-4). If technologically necessary might be used the function of soft stop.


Complete specification

High-voltage soft starter SAMSON is invented for solving the tasks of soft start and stop of the motors with power capacity from 280 to 3600 kW and voltage from 2,3 kV to 10 kV.

Advantages of the soft starter SAMSON:


  • manufactured as an integrated system for concrete tasks solving;

  • full conformity with the standards and requirements of the Electrical installation code;

  • circuit breaker-grounding conductor, vacuum bypass contactor in a basic version;

  • bar for gap visibility:

  • reverse function of the motor:

  • opposite connection stop;

  • multi-start function;

  • reduces the multiplicity of starting current motor from 5-7 up to 3 times;

  • easy embeddability in an existing automated control system object.


Types of SAMSON complete sets:


  • basic - soft start of the motor;

  • input cabinet – soft start of the motor with the reverse function or opposite connection stop with the limitation and control of the current;

  • multi-start function with the set of output cabinets of the motor - soft gradual start of several motors


SAMSON options:


  • operation with synchronous motor;

  • connection protocols like ModBus RTU, ProfiBus DP, DeviceNet, RTD;

  • block-module execution;

  • expansion board, ACS cabinet;

  • remote control display;

  • set of output cabinets of the motors (for the fulfillment of multi-start function with the gradual start of several devices);

  • units of additional protection;

  • input cabinet (for the fulfillment of the reverse function or opposite connection stop);

  • set of spare parts.


Operational tests showed significant reduction of start currents due to the use of high-voltage soft starter:


  • problems of ACS upper level failure and system overload are solved;

  • motors have soft bumpless start;

  • reverse is made with the soft stop mode;

  • technological temporary reverse standards are maintained.


Direct start mode (without complete high-voltage frequency inverter)
Soft start mode (with complete high-voltage frequency inverter)

1. Rated current of the motor 194А (according to the specification).

2. Overload during acceleration of 560% (approximately 1100А) (according to the data on the supply substation devices).

3. Acceleration time about 11 sec (according to the data on the supply substation devices).

4. Start is made in both directions on all devices.

1. Rated current of the motor 194А (according to the motor specification).

2. Overload during acceleration 300% (approximately 600А) (according to data of the soft starter).

3. Acceleration time about 32 sec (according to data of the soft starter).

4. Start is provided in both directions on all devices.


All our SAMSON soft starters are compliant and really operate with the upper level control systems.

We offer all kinds of work from design and site inspection to service and maintenance.
