Recently, Qirod Electric QD200 series inverters have been successfully applied to the transformation of the constant pressure water supply comprehensive project of Tianfu Thermoelectric Heating Company of the Eighth Division of Xinjiang Production and Construction Corps. After the transformation, the system runs stably and the operation is simple and easy to understand. Comfortable heating at the same time, but also achieved good energy saving effect.

Xinjiang Shihezi Tianfu Thermal Electricity Heating Company is the only legal heating supplier in Shihezi City, the Eighth Division of Xinjiang Production and Construction Corps. It undertakes winter heating duties for the entire population of 700,000 Shihezi City. 6 new heat exchange stations have been built, 30 kilometers of pipe network have been laid, and the maintenance tasks of 132 heat exchange stations, 110 kilometers of primary network, secondary network and other facilities and equipment have been completed. This year, the entire constant pressure water system has been completely transformed.

The transformation of this project has been highly valued by the leaders of the heating company. The system originally used DCS and PLC from ABB in Switzerland. Due to the harsh site environment and the large temperature difference between day and night, the entire system basically requires an operation rate of close to 100% during the heating period. The executive part of the system, the inverter, has high requirements. Therefore, customers are cautious and meticulous in the selection of frequency converters, comprehensively considering price and performance and other aspects, not only to adapt to the harsh weather in Xinjiang, but also to have high equipment reliability, advanced performance such as overcurrent, overload, and heat dissipation. From the very beginning of the project, we closely followed the customer's needs, and developed special software functions for the customer's differentiated requirements, such as matching the inverter communication with the ABB system, and provided "squatting" services during the later equipment installation, commissioning, and trial operation. , has won unanimous praise from customers.
