Model Meaning

Functions and Features
◆ High-voltage switchgear, transformer, low-voltage switchgear trinity, strong completeness;
◆ Perfect high and low voltage protection, safe and reliable operation, simple maintenance;
◆ Less land occupation, low investment, short production cycle, easy to move;
◆ Flexible and diverse wiring schemes;
◆ Unique structure: unique honeycomb structure double-layer (composite plate) shell firm, heat insulation and heat dissipation ventilation, beautiful appearance, high protection level, shell materials are stainless steel Qin alloy, aluminum alloy, cold-rolled plate, color steel plate optional;
◆ Various types: general-purpose, villa-type, compact and other styles;
◆ The high-voltage ring network cabinet can be equipped with a network automation terminal (FTU) to realize the reliable detection of short circuit and single-phase ground fault, and has the “four remote” function, which is convenient for the automatic upgrade of the distribution network.
◆ The altitude does not exceed 1000m;
◆ Ambient temperature: -25°C ~+40°C;
◆ Relative humidity: daily average is not more than 95%, monthly average is not more than 90%;
◆ Installation site: no fire, explosion risk, conductive dust, chemical corrosive gas and severe vibration place, if the above conditions are exceeded, the user can negotiate with our company.

Conditions of Normal Use
The intelligent integrated substation adopts low-loss, oil-immersed, fully sealed S9, S10, S11 series transformers, and can also choose resin insulated or NOMEX paper-insulated environmentally friendly dry-type transformers, and the bottom can be equipped with a trolley, and the transformer can be easily entered and exited.

Transformers
Intelligent integrated substation high voltage generally adopts load switch and fuse combination electrical protection, fuse one phase after fusing, three-phase linkage tripping, load switch has compressed gas, vacuum, sulfur hexafluoride and other types of optional, can be equipped with electric operating mechanism, to achieve automation upgrade; The fuse is a high-voltage current limiting fuse, with impactor, reliable action, large breaking capacity, the main technical parameters are shown in the following table. For transformers above 800kVA, QCE4, QCE2, QCE1 and other vacuum circuit breakers can be selected.

High voltage side
The low-voltage side main switch adopts universal or intelligent circuit breaker for selective protection; The outlet switch adopts a new molded case switch with small size and short arc, up to 30 circuits; Intelligent automatic tracking reactive power compensation device, there are contactor and contactless two switching methods for users to choose.
