ZGS-Z(H)/12 combined transformer
ZGS-Z(H)/12 combined transformer (American box substation) is a series of products developed by Tianan Electric after digesting and absorbing foreign advanced technology. It is used in 10/0.4kV, 50Hz power distribution system. The rated capacity of the transformer is 50 ~1600kVA. The product puts the transformer body, high-voltage load switch, fuse and other components together in the transformer tank, and uses the insulating liquid of the transformer as the insulating medium and heat dissipation medium of the entire product. It has the characteristics of compact structure, small size, convenient installation, flexibility and beautiful appearance.
Scope of application: Urban public power distribution system, urban lighting street lamp change, and temporary power supply for construction sites.
1）Fully insulated, fully sealed structure, safe and reliable, maintenance-free, reliable protection of personal safety;
2）The high-voltage side adopts double fuse protection, in which the plug-in fuse is a dual sensitive fuse (temperature, current), and the backup fuse is a current-limiting fuse to reduce operating costs;
3）The high-voltage incoming line adopts a cable connector structure, which is fully insulated, safe and reliable, and easy to operate;
4）It can be used for both ring network and terminal. The conversion is very convenient and the reliability of power supply is improved;
5）The transformer has a three-phase three-column or three-phase five-column structure, and the iron core adopts a stepped joint process or a rolled iron core process, which has low noise, low loss, and strong short-circuit and overload resistance;
6）The special process of vacuum drying and vacuum oil injection is adopted;
7）The cabinet can adopt anti-corrosion design and special painting treatment according to the requirements of the operating environment.
