CHETA LLC Production System of soft starter
System of soft starter Print

Soft starting systems based on high-voltage soft-starters and compartments RSN-10 (technical information KSPE.140.001-13), which are manufactured like full design, that means a soft-starter is integrated to a switchgear 6(10)kV. The system decreases starter current in synchronous and asynchronous electro motors up to 17,4 Mega Watts, dynamic shock load on wire mechanisms, voltage slump in a network and increase of service life of installed equipment in various branches of industry and energy. Relative start-up current 2-6 J rated is previously agreed with a customer

Topology: three phases thyristor’s voltage controller.

Nominal operating conditions - intermittent (S3) as per GOST IEC 60034-1-2014 with time of continuous operation up to 90 seconds (three starts in a row from the start time up to 30 sec.), the load transfer to bypass followed by a pause of at least 10 minutes.

As a rule soft starter’s system have an industrial controller, which completes tasks of automatic, handle, distance site control. This device is installed in busbar assembly’s panel or teleautomatic panel, which control the work of whole distribution device.

Products of world’s leading companies are used like power thyristor and control modules of systems of soft starters.

Outside switching devices based on a removable vacuum circuit breaker, withdrawable and fixed vacuum contactors. As a rule one system with soft starter intended for starting from one to five motors. Data of 2 different power drives could be programmed to the control system of soft starter, it’s increase flexibility of work.

More information is in TU 3414-005-5408888-2015 and the work instruction KSPE.674.21.001RE.

Type designation of high-voltage soft starters.

Examples of high-voltage soft starters’ designation:

VUPP-60250-220AC UHL4 – a high-voltage soft starter of motor drive 6kV, rated currency up to 250A, control voltage 220V, frequency 50Hz. It is better to order high-voltage soft starters using questionnaire for analyses of usage mode.

Particular systems of technical equipment’s control of customer are designed and manufactured individually with due regard to all requirements, reflected in the questionnaire.

As a rule these systems are designed, manufactured and delivered to a customer in block modular buildings with maximal readiness. Systems that provide optimal temperature conditions for the reliable operation of all equipment of the complex, regardless of the outside temperature in the range from + 35 ° C to -60?S are built in the buildings. These solutions make possible to mount an object, perform start-up works and commission it for 45-60 days.
