YB pre-installed substation

Product Description

Product overview

Widely used in urban power grid transformation, residential areas, high-rise buildings, industrial and mining, hotels, shopping malls, airports, railways, oil fields, docks, highways and temporary power facilities and other indoor and outdoor places.

Product characteristics

High voltage switchgear, transformer, low voltage switchgear trinity, complete sets of strong; High and low pressure protection, safe and reliable operation, simple maintenance;

Small footprint, less investment, short production cycle, easy to move;

Flexible wiring scheme;

Unique structure: unique honeycomb structure double layer (composite board) shell is strong, heat insulation and heat dissipation ventilation, beautiful, high protection level, shell materials are stainless steel alloy, aluminum alloy, cold rolled plate, color steel plate optional;

Various types: universal type, villa type, compact and other styles;

The network automation terminal (FTU) can be assembled in the high voltage ring network cabinet to realize the reliable detection of short circuit and single-phase grounding fault, and has the "four" function to facilitate the automatic upgrade of the distribution network.

Product model and meaning

Normal service condition

Ambient temperature :-25C~+40C;

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

Installation site: no fire, explosion danger, conductive dust, chemical corrosive gas and violent vibration of the place, if beyond the above conditions, the user can negotiate with our company.

Transformer

Intelligent integrated substation selection of low loss, oil immersed, fully sealed S9, S10, S11 series transformers, can also choose resin insulation or NOMEX paper insulation environmentally friendly dry transformer, the bottom can be equipped with a car, the transformer can be convenient access.

High pressure side

Intelligent integrated substation high voltage generally adopts load switch and fuse combination electrical protection, fuse one phase of the fuse fuse, three-phase linkage trip, load switch has pressure type, vacuum, sulfur hexafluoride and other types of optional, can be equipped with electric operating mechanism, automation upgrade: fuse for high voltage current limiting fuse, with impactor, reliable action, large breaking capacity, The main technical parameters are shown in the table below. For transformers above 800kVA, QCE4, QCE2,QCE1 and other vacuum circuit breaker protection can be selected.

Low pressure side

The main switch on the low voltage side adopts universal or intelligent circuit breaker, selective protection, and the outgoing switch adopts a new plastique switch with small size and short fly-arc, up to 30 circuits: intelligent automatic tracking reactive power compensation device, with contactor and contactless switching methods for users to choose.

Installation, maintenance and use

Intelligent integrated substation in the installation, acceptance, handover test, operation and maintenance in addition to the requirements of the power department, pay attention to the following matters: the user should be carefully checked according to the relevant provisions when receiving the goods, for not immediately installed products, should be stored in the normal conditions of use, in an appropriate place; The product should be lifted at the bottom using special spreader; The product is placed horizontally on the basis made in advance, and then the gap between the product base and the foundation is sealed with cement slurry to prevent rain from entering the eight cable room, and the high and low voltage cables are accessed through the bottom sealing plate of the high and low pressure room;

The two main ground terminals on the channel steel of the base of the power station, the neutral point of the transformer and the shell, and the pile head under the arrester should be grounded by the installation department respectively. All grounding devices shall share a set of grounding devices, the grounding resistance shall be less than 4 ohms, and no less than two grounding leads shall be led from the grounding network to the product. After installation or maintenance, the product shall be inspected and tested in the following items before operation;

Whether the substation is clean;

Whether the operating mechanism is flexible;

Whether the main electrical appliances are flexible and reliable;

Whether the electrical auxiliary contact is reliable and accurate;

Meter and relay operation is accurate.
