G7 series water cooling high voltage frequency inverter Product structure

Transformer cabinet
It contains phase-shifting transformer, temperature sensor, current and voltage detection device. Phase-shifting transformer provides independent three-phase input power supply for power unit; The temperature sensor monitors the internal temperature of the transformer in real time to realize the functions of over temperature alarm and over temperature protection; The current and voltage detection device can monitor the input current and voltage of the transformer in real time to realize the protection function of the frequency converter. Independent air duct design reduces transformer temperature rise and prolongs service life.

Switching cabinet
When the frequency inverter fails, the motor can be switched to the grid power from the frequency conversion to continue operation. There are two types of switching: automatic and manual. The difference is that the manual switching cabinet needs to switch the main circuit according to the operating procedures; And the automatic switching cabinet can automatically switch the main circuit under the system control, except during maintenance. The switching cabinet is non-standard and needs to be customized according to the user's on-site requirements.

Power unit cabinet
There are power units inside. Each power unit is completely consistent in structure and can be interchanged. Its shell adopts mold integrated design and has good sealing performance. It is suitable for occasions with high tide humidity, multi dust and multi corrosive gas. The power cabinet communicates with the control cabinet through optical fiber, which can effectively suppress electromagnetic interference.

Control cabinet
It contains HMI, ARM, FPGA, DSP and other high-precision chips. Multi language human-machine interface, less parameters and easy operation; Rich external interfaces, convenient for connection with user system and field expansion. The main controller uses the self-developed box structure for packaging. The box has passed the strict EMC certification and the treatment of temperature cycle and vibration test, with high reliability.
