SGQH high voltage solid state soft starter cabinet product overview
Xi'an Taifu Xima SGQH high-voltage solid-state soft start cabinet is a new type of medium and high voltage motor soft start cabinet, which has been widely used in foreign countries. It is mainly suitable for medium and high voltage AC squirrel cage motors below 10kV. It uses DSP control technology and power electronic technology. And the thyristor series-parallel technology fully controls and comprehensively protects the motor. Compared with other traditional starting methods, its unique intelligent control mode can easily and accurately set the starting torque, starting current, starting time and downtime. Such parameters can be networked with microcomputers and PLCs. The high-voltage solid-state soft starter cabinet also has the advantages of small size, low power consumption, high reliability, high sensitivity, no contact, no maintenance, no environmental pollution, and convenient installation.
Xi'an Taifu Xima SGQH high-pressure solid-state soft start cabinet is now in the machinery manufacturing, cement production, metallurgy, mining, oil production, chemical, water treatment, petrochemical and other industries pumps, fans, pumping units, air compressors, ball mills, cranes, compression It is widely used in various loads such as machines, crushers, conveyors, elevators, centrifuges, and rolling mills.
Taifu Xima SGQH high-pressure solid state soft start cabinet performance characteristics:
1. It adopts the original imported series thyristor and professional insulating materials combined with modern power electronic control technology, professional design and manufacture; suitable for large and medium-sized motor characteristics and characteristics of high-pressure solid-state soft starter.
2, high reliability: the main circuit of the device adopts modular structure, modular installation mode; with multiple overvoltage absorption and protection technology; transient dv/dt, lightning impulse voltage, operating wave overvoltage, transient transition process Multi-layer limiting clamps are performed; unique measures and methods are available for di/dt, equalization of valve opening process, and pressure equalization of valve closing process.
3. Perfect isolation between strong and weak electricity: The digital trigger cabinet with high anti-interference system is matched with optical fiber isolation or CT isolation transmission technology to avoid mutual interference between strong and weak electricity, so that the high voltage performance and low voltage of the device The device is as safe and reliable;
4. Unique fault detection return and judgment system, which can quickly transmit the test result to the control circuit, sound and light alarm and take corresponding measures at any time to prevent the fault from expanding;
5, high-voltage soft start cabinet with >96% high efficiency (up to 97%) is much more efficient than other soft start cabinets;
6, a variety of perfect protection functions: short circuit, over current, current limit, over voltage, under voltage, overload, phase loss, three-phase current imbalance, overheating, communication failure and other fault status alarms timely protection protection soft Starter cabinet and motor;
7. The unique heat dissipation and design enable the thyristor components to be effectively cooled;
8, any optional soft start function, including standard soft start, constant current soft start, dual voltage ramp start, soft start with kick function;
9, with small size, low power consumption, high sensitivity, no contact, easy to install and so on.
