Model Meaning

Features

◇ High-voltage switchgear, transformer, low-voltage switchgear trinity, strong completeness;

◇ Perfect high and low voltage protection, safe and reliable operation, simple maintenance;

◇ Occupy less land, save investment, short production cycle, and easy to move;

◇ Flexible and diverse wiring schemes;

◇ Structure: honeycomb structure double-layer (composite plate) The shell is firm, heat insulation, heat dissipation and ventilation, beautiful, high protection level, and the shell materials are stainless steel alloy, aluminum alloy, cold-rolled plate, color steel plate are optional;

◇ Various types: general-purpose, villa-type, compact and other styles;

◇ The automatic terminal (FTU) of the assembly network in the high-voltage ring main unit realizes the reliable detection of short circuit and single-phase grounding fault, and has the function of "four remotes", which is convenient for the automatic upgrade of distribution network.

Working Conditions

◇ The altitude does not exceed 1000m;

◇ Ambient temperature: -25°C ~+40°C;

◇ Relative humidity: the daily average value is not more than 95%, the monthly average value is not more than 90%;

◇ Installation site: no fire, explosion hazard, conductive dust, chemical corrosive gas and violent vibration place, if the above conditions are exceeded, the user can negotiate with our company.

Transformer

The intelligent integrated substation can choose low-loss, oil-immersed, fully sealed S9, S10, S11 series transformers, or 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.

High Pressure Side

Intelligent integrated substation high voltage generally adopts load switch and fuse combined electrical protection, after the fuse is blown in one phase, the three-phase linkage trips, and the load switch has compressed gas type, vacuum, sulfur hexafluoride and other types are optional, and can be equipped with an electric operating mechanism to achieve automatic upgrading; the fuse is a high-voltage current limiting fuse, with an impactor, reliable action, large breaking capacity, and 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.
