Product Introduction

This product is to absorb foreign professional technology, combined with the actual situation in China research and development, the whole product has the characteristics of small size, easy installation and maintenance, low noise, low loss, anti-theft, strong overload capacity, full protection and so on. It is suitable for new residential areas, green belts, parks, station hotels, construction sites, airports and other places.

ZGS-12 series American-style pre-installed box-type substation is suitable for 10kV ring network power supply, dual power supply or terminal power supply system, as a substation, metering, compensation control and protection device. This product meets the following standards: GB/T17467-1998 "High Voltage and Low Voltage Prefabricated Substation", DL/T537-93 "Technical Conditions for Ordering 6-35kV Box-type Substation"

Model Meaning

Features

◇ Fully insulated, fully sealed, maintenance-free, reliable to ensure personal safety;

◇ Compact structure, only 1/3-1/5 of the same capacity of the European variant, low height;

◇ Split-box structure can be adopted to avoid the pollution of oil in the transformer tank;

◇ The high-voltage side adopts double-fuse full-range protection, which greatly reduces the cost:

◇ It can be used for both ring network and terminal, and the cable head can be urgently plugged and unplugged when the load current is 200A;

◇ The cabinet body adopts honeycomb double-sandwich composite panel, which has the functions of temperature insulation and heat dissipation;

◇ The electronic phase loss protector is installed on the low-voltage side, which can quickly break the main switch when there is abnormal voltage in the system;

◇ The oil-immersed load switch or SF6 load switch on the high voltage side can be upgraded electrically, laying the foundation for the realization of distribution network automation.

◇ Oil-immersed S9 or S11 series transformer with better performance is adopted.

Working Conditions
