Product Description
Product Origin:China
Brand Name:INVT
Price Terms:
Payment Terms:
Certification:ISO9001
Description:Features: 1) ±20% voltage fluctuation design, applicable to the power grid conditions of large industrial and mine enterprises in China 2) The SVPWM optimized modulation technology in conjunction with the professional waveform processing circuit reduces the heat dissipation of the integrated equipment by over 1/3, to improve the stability and service life of the product 3) The photoelectric isolation technology is applied to the control and drive circuit of the inverter, to achieve accurate signal collection and control as well as sensitive and accurate protection in case of any faults 4) Multi-load operation control and protection, such as, overcurrent, overvoltage, overload, undervoltage, phase failure, short circuit 5) Flexible control modes, such as, RS-485 control, PI regulation, multi-step speed, program control, proportional linkage, and free programmable setting of control terminal and analog signal terminal, for the convenience of the forming of multiple control systems 6) Customizable water-cooling and explosion-proof inverters 7) A warranty period of 18 months, and life-long maintenance Technical features: 1) The open Y structure on one side of the transformer is changed to the edge- prolonged triangle structure with a closed loop, used to absorb the higher-order harmonic during frequency inversion. Thus, the higher-order harmonic at the high voltage side can be reduced to less than 1.6% 2) High voltage operation is reserved, but it operates at low voltage. The efficiency is equal to or greater than 95% after rebuilding, and the power factor is equal to or greater than 0.94 3) This solution features high efficiency, high power factor, high reliability, low harmonic, short construction period and short investment return period. The cost is only half of a direct high-voltage inverter 4) Supporting switchover between power frequency operation and variable frequency operation, to ensure seamless production 5) Compared with high-voltage inverters (systems) in high-low-high mode used in energy-saving rebuilding of high-voltage motors, INVT high-low mode inverters feature high efficiency, high power factor, high reliability, simple installation and debugging and small occupation area High-voltage (3 - 10KV) motors suit medium and low-voltage (380V - 1,140V) frequency conversion and speed control by means of changing the inter-phase winding connection structure (Y shape, shape and edge-prolonged triangle), inter-pole winding connection structure (tributary in serial and parallel connection) and inter-pole coil connection structure (loop in serial and parallel connection). A special transformer is used to reduce the high voltage to the necessary low voltage, and then an INVT 380 - 1,140V inverter matching the voltage range is used, in conjunction with a power frequency backup control loop, to complete the low-voltage frequency conversion and speed control system of high-voltage motors.
