Brief introduction of Nanjing Chen Guo Information Automation Co., Ltd.

Severe voltage sag will stop the use of electrical equipment or lead to the decline of product quality. However, the severity of voltage sag varies with the characteristics of electrical equipment. Generally speaking, industrial process equipment is particularly sensitive to voltage sag, because any component in the equipment will stop the whole process because of power supply problems. These industrial processes involve automobile, semiconductor, plastic, petrochemical, textile, optical fiber, beverage and dairy industry, mobile communication and other fields. Important equipment often affected by voltage sag includes cooling device control, DC motor drive, programmable logic controller (PLC), mechanical device, speed regulating drive device, etc.

Chen Guo Company is committed to the comprehensive solution of various power quality incidents (commonly known as "power surge") and inverter tripping problems in continuous production enterprises, as well as the research and development of a new generation of anti-surge equipment. With the leading industry technology and experience, Chen Guo Company provides enterprises with overall power supply optimization solutions and technical consulting services, furnace safety powder feeding solutions, power plant powder feeding anti-surge solutions, IT machine room overall solutions, industrial site anti-surge overall solutions and anti-surge solutions for all kinds of load types.

Relying on many years' experience in frequency conversion agency and technical precipitation, Chen Guo Company has conducted in-depth research on the characteristics of frequency converter connected to large inertial load, conducted special research on the uncontrolled start-up when load energy collapses and power jitter, and conducted in-depth research on various load characteristics such as motor fan, water pump, hoist and booster pump. , and mastered the manufacturers and models of various inverters, which have been successfully supported in several anti-sloshing projects. Even for individual inverter manufacturers that do not support DC, the problem can be solved through technical improvement. Related research and cases have published many papers.
