The rise of CCD in western Zhengzhou, SmartGen supports the central plains “Four Centers” project

The brand new “Central Cultural District (CCD)” in the west of Zhengzhou had been invested with 30 billion Yuan (RMB), is a provincial key project and a major people’ s livelihood project of the municipal party committee and municipal government, which benefits the people a lot. The project consists of four centers: the Olympic Sports Center, the Wenbo Arts Center, the Civic Center and the Modern Media Center.

SmartGen’ s products are not the first time applied in the CCD project. Last year, the Olympic Sports Center, one of the “Four Centers”, where our geneset control modules were used in the venue of the National Traditional Games of Ethnic Minority of People’ s Republic of China. This time, SmartGen’s two-line one-bus automatic switching control modules are once again applied in one of the “Four Centers”—the “Civic Center” power distribution project, providing great power switching support for the center.

Project Introduction

The power distribution project of the Civic Center is provided by two-way mains supply, four-way transformers, two sets of two-line one-bus system. Each mains circuit is divided into two transformers, which are combined two-line switch cabinets and a busbar connection cabinet into a two-line one-bus automatic switching system. The importance of the project is highlighted by the configuration of “two-way mains, four-way transformers, two sets of two-line one-bus”.

Project Application

1. The ACB breakers of the line cabinet and connection cabinet are MTZ2 of Schneider Electric, and the automatic switching control modules are HAT821 of SmartGen.
2. The field application is the mode in which both the two lines are used as the main use mode (S1 is used as the main mode and S2 is used as the main mode). When the two way power supplies are normal, the two incoming circuit breakers close the power supply respectively, and the bus connection is in the state of disconnection. In case of any abnormal, the other breaker and bus breaker close to supply power for the two loads.
3. The bus control module also has S1 main use mode and S2 main use mode for users to choose, and the automatic state can also choose two modes of state: auto change, auto recovery and auto change, manually recovery.
4. The bus system has three operating modes:
①The control module can realize automatically control and switch automatically according to the main use mode setting.
②Manual button control, 6 buttons directly control the circuit breaker’ closing and opening.
③Manual button control, switch button on each cabinet to achieve on-site operation.
5. Through the two groups of normally closed auxiliary contacts of each circuit breaker, the electrical linkage can be formed. No matter the control module operation or the on-site button operation, the three circuit breakers can only close two, realizing the reliable interlock between the three circuit breakers.

Western Zhengzhou CCD and Eastern Zhengzhou CBD echo each other at a distance, “flying wing to wing” and going mutual development. Fortunately, SmartGen is located in this more and more attractive city, let’ s strive for the constuction by our excellent products and light for myriad families of the city.
