requirement analysis

The petrochemical industry mostly involves high temperature, high pressure, inflammable and explosive, DCS and instrument system. Once abnormal, it will cause production accidents, casualties and economic property losses. All kinds of challenges are brought to life's operation and management:

When UPS maintenance and battery regular maintenance are carried out, the power distribution system cannot operate normally;

There is unacceptable disturbance during switching of all power systems of the instrument;

The power quality of the direct supply and output circuit of the low-voltage bus is poor.

Basic configuration scheme

Ubersch's industrial grade online power system, intelligent induction voltage regulator and other power system solutions for the petrochemical industry guarantee the stable operation of the system. Ubersch has a 1kva-200kva series UPS product line, and its UPS product power supply system includes single in single out, three in single out, three in three out, to meet the needs of the main business, public system and logistics system of the petrochemical industry, and to guarantee the stable operation of the petrochemical system.

Advantages of basic configuration plan

Based on the characteristics of low disturbance and continuous operation, the industrial grade On-line UPS power supply system of Weidi makes use of DSP digital control technology to make data processing fast, output performance excellent, improve the availability of the machine, and reduce the cost of manpower and capital for system maintenance.

Various loads of main business, public system and logistics system in petrochemical industry aggravate the deterioration of power quality of low-voltage bus. The intelligent induction regulated power supply system adopts non-contact voltage regulation, with fast response time and low noise, which can solve the problem of poor power quality of the direct supply and feed circuit of the low-voltage bus.

All copper F-class isolation transformer system reduces cost and has strong anti-interference ability. The PLC or actuator which is used to compare the interference signals can obtain relatively good power supply in the direct feed circuit of the low voltage bus. The △ type connection method is adopted for the input end of the isolation transformer, and the neutral line is not introduced. The Y type connection method is adopted for the output end to realize the electrical isolation between the input and output and reduce the interference of the low-voltage bus to the equipment.
