Pre-Installed European Type Substation Box Type Substation

Pre-Installed Power Transformer Substation:

As a new product independently researched and developed by our company to meet market demand and in combinaton with scientific research achievements and engineeing practice expeience of power distribution field, intelligent combined transformer substation/switching station provide the best solution for new transformer substation of 110KV, 72KV and 40.5KV, and features advantages such as high reliability, small size, no pollution, low operation cost, flexible combination, convenient installation, automation, free from service, simple operation and unattended operation. It replaces traditional engineering program of civil work substation. It can substantially reduce investment of transformer substation, land occupation and construction period, and has propelled overall enhancement of operation level of transformer substation. Comprehensive automation system of transfomer substation adopts scattered/distributed structure in term of design, allocates most of protection and control functions in switch compartment, and realizes perfect combination of compact primary equipment and scattered secodary equipment. It realizes share of infomation through computer network, eliminates all redundant hardware, and realizes intelligence and integration of product design, factory-based production process and simplicity of onsite installation. Meanwhile, technical level and safe/stable operation level of transformer substation have been enhanced to new level.
Prefabricated transformer substation can be used as ring main type and terminal type of power transformation/power distribution device. It is widely used in outdoor locations such as residental district, industrial and mining enterprises, hotel, hospital, department store, airport, park and railway.

Product Characteristics:

1. Basic structure of cubicle transformer substation falls into two categories of rectangular or triangular arrangement, cubicle-type skeleton adopts welding of high quality channel steel and angle steel, and features high mechanical strength; cubicle body adopts aluminum alloy section material, features good corrosion resistance, painting color of exterior is hamonized with ambient environent, and carefully designed bottom hoisting device provides exteme convenience for installation, transportation and movement.

2.Cubicle transformer substation features independent high-voltage chamber, transformer chamber and low-voltage chamber, of which illumination is automatically turned on with opening of door. High-voltage chamber is installed with high-voltage ring main switchgear, it is possible to select air compression type and vacuum type load-breaking switch, and "five-proof function is available, in case of adoption of current limiting high-voltage fuse, load-breaking switch is automatically opened upon breaking of fuse of a certain phase, so as to avoid malfunction caused due to phase-deficient operation.

3.Transformer chamber adopts natural ventilation and automatically controlled forced heat radiation air cooling device, features exhaust system automatically controlled as per change of temperature, effective control and reduction of temperature inside cabinet, and meets operation requirements. In accordance with user's requirement, it is also possible to adopt anti-condensation device, and configure track to facilitate entry/exit from gate at both sides of transfomer chamber. Cubicle material can prevent ingression of rain water and filthy, meet conditions for long-term outdoor usage, feature corrosion resistance, water proof, dust proof, long usage life, simple maintenance and pretty appearance, etc.

4.Transfomer can adopt dry type or oli immersion transformer, and oli immersion transformer can adopt two types with oil conservator or without oil conservator fully-sealed.    

5.Low-voltage features overall function of complete switchgear for selection by user and any combination

6.Enclosure materal: enclosure materal includes composite plate, aluminized zinc sheet, stainless steel plate, metal carving plate and environmental protection timber, etc.

7.Structural features: high-voltage structure is reasonable and compact, can select SF6, FZN57 and VHC ring main cabinet, and features five-proof interlock function. Natural ventilation and automatic air cooling system of transformer applies to dry type and oil immersion transformer.

8.Low-voltage chamber: power distribution program of multiple structures can be adopted as per user's requirement, and features various functions such as power distribution, illumination power distribution, automatic reactive compensation and electric energy metering, automatic illumination system, high dust proof perfomance, long usage life, simple maintenance and beautiful appearance.
