10KV Medium Voltage Soft Starter Optical Fiber Isolation Technology Top Brand in CN Be Combined With KYN28 Switchgear



10KV Medium Voltage Soft Starter Top Brand in CN, Used On Coal Mine, Pumping Station For Chile Peru Etc is widely used in power system, mechanical manufacturing, cement production, metallurgy, mining, oil production, chemical industry, water treatment and other industries of squirrel-cage AC motor.

As three-phase voltage 3--10 KV high voltage motor starting, control, protection, soft stop. After strict EMC test, the control system has been tested and qualified, so it has high anti-electromagnetic interference performance, and has completely independent intellectual property rights of soft starter control technology. The ability to upgrade the free software control system for users to ensure that the technology of the product is always in the leading position; negative feedback function: use dynamic fuzzy control concept, according to the size of the load torque, Automatically adjust the starting time and starting torque of the motor. Thus, the motor can be smoothly accelerated. When the motor speed reaches the rated working speed, the bypass contactor automatically absorbs, which solves the problem of mismatch between the artificially set starting curve and the load torque curve.

1. Free of maintenance:Thyristor is an electric device without contacts. Different from other kinds of products that need frequent maintenance on liquid and parts etc., it turns the mechanical lift into the service life of electronic components, so it needs no maintenance after running for many years.

2. Easy installation and operation:NKS300 is a complete system for controlling and protecting the starting of motor. It can put into operation only with the power line and motor line connected. The whole system can be tested electrically under low voltage before operating with high voltage.

3. Backup:The starter comes equipped with a vacuum contactor which can be used to start the motor directly in the inside. If NKS300 fails, the vacuum contactor can be used to start the motor directly to ensure the continuity of the production.

4. High voltage thyristor is a component of major loop, equipped with voltage balancing protection system and over-voltage protection system.

5. NKS300 comes equipped with an electromagnetic blocking device for fear of entering the high voltage device in the electrified state.

6. Advanced optical fiber transmission technique realizes the triggering detection of high voltage thyristor and the isolation between LV control loops.

7. 32-bit ARM-core microcontroller is used to perform central control which is real-time and high efficient with , high reliability and excellent stability.

8. LCD/touch screen display system in both Chinese and English with human-friendly operation interface.

9. RS-485 communication port can be used to communicate with the upper computer or centralized control center.

10. Aging experiments are made on all circuit boards.
