An overview of the
Widely used in city network reconstruction, residential area, high-rise buildings, industrial and mining, hotels, shopping malls, airports, docks, highway, railway, oilfield and temporary electricity facilities and other places of households inside and outside.

Model and meaning

Conditions of use

The ponent altitude does not exceed 1000m;

Ambient temperature: ℃ to 25 ℃ ~ + 4 o;

The daily average value is not greater than 95% and the monthly average value is not greater than 90%.

Where there is no fire, explosion danger, conductive dust, chemically corrosive gas and severe vibration, users may consult with our company if the above conditions are exceeded.

Functions and features

The overhaul is a three-in-one system of high voltage switching equipment, transformers and low voltage switching equipment with strong overall performance.

The balance between high and low voltage protection is perfect, the operation is safe and reliable, and the maintenance is simple.

Less land area, less investment, shorter production cycle and more convenient movement;

The balance connection scheme is flexible and diverse.

Unique structure: unique cellular structure of the double (composite board) shell and firm, heat insulation and cooling ventilation, beautiful, high protection grade, shell material with qin alloy, aluminum alloy, stainless steel manufacture, choi steel optional;

The various forms of fraud are universal, villa and compact.

The reliable detection of short-circuit and single-phase ground fault can be achieved by assembling the automatic network terminal (FTU) in the high voltage loop cabinet.

transformer

Integration of intelligent substation choose low loss, oil-immersed, fully sealed the integrated, S10, S11 series transformer, also can choose resin insulation or NOMEX paper insulation environmental protection dry type transformer, the car can be equipped on it, at the bottom of the transformer can be easily in and out.

High side

Commonly used intelligent integrated substation high-voltage load switch a fusing machine combination electric protection, fuse fusing after a phase, three phase tripping linkage, load switch with pneumatic, vacuum, sulfur hexafluoride, such as type of optional, can match the electric operating mechanism, automatic upgrade;

The fuse is a high voltage current limiting fuse with an impactor. It has reliable action and large capacity. The main technical parameters are shown in the following table.

For transformers over 800KVA, ZN12, ZN28, VSE1 and other vacuum circuit breakers can be selected for protection.
