Product Details

 

Overview
YBM3A-12/0.4 series prefabricated substation is designed and produced to meet the needs of domestic users. It has the advantages of compact structure, strong complete set, safe and reliable operation, convenient maintenance, beautiful appearance, small footprint, and convenient movement. Product performance reached the domestic advanced level.
 
Features
The shell is designed with reference to foreign advanced technology and according to the actual situation. It has the characteristics of firmness, good heat insulation and ventilation, dustproof, anti-small animal, moisture-proof, beautiful appearance, convenient maintenance, etc. The shell material is aluminum alloy plate, steel plate, composite plate and other materials to choose from.
The high-pressure side adopts air-pressure type, SF6 load switch or vacuum load switch, which has reliable anti-misoperation function. Transformers can be oil-immersed transformers, fully sealed transformers, and dry-type transformers. The low-voltage side adopts the latest type of plastic shell automatic air switch, with high breaking capacity and good protection performance. Up to 30 YBM3A-12/0.4 outgoing circuits.
Automatic reactive power compensation devices can also be used when required by users.
The substation is equipped with a self-controlled exhaust device, which can meet the requirements of high temperature areas. At the request of the user can also be equipped with anti-condensation dehumidification heating automatic control device to meet the special requirements of alpine regions.
The substation is easy to install, and a movable bottom plate is installed in the low-voltage room of the substation, from which people can directly enter the cable trench.
Substation has a variety of design options for selection.
On the basis of ordinary box-type substation, it can be made into landscape box-type substation by embedding wood board, ceramic tile and other decoration materials or matching with other decoration materials according to user requirements.
 
Normal use environmental conditions
● The altitude does not exceed 1000m.
● The ambient air temperature is not higher than 40 ℃, not lower than 25 ℃.
● Outdoor wind speed does not exceed 35 m/s.
● Relative humidity: the daily average value is not more than 95%, and the monthly average value is not more than 90%.
● Installation location: installed in no fire, explosion hazard, no serious pollution, chemical corrosion and severe vibration of the place.


 

The switch cabinet has the functions of overhead incoming and outgoing lines, cable incoming and outgoing lines, bus connection, etc. Mainly suitable for power plants, substations, petrochemical, metallurgical steel rolling, light industry and textile, factories and mining enterprises and residential areas, high-rise buildings and other different places. It mainly includes high-voltage isolating switch and grounding switch, high-voltage load switch, high-voltage automatic coincidence and segmenter, high-voltage operating mechanism, high-voltage explosion-proof distribution device and high-voltage switch cabinet.

Correct Selection of Breaker Breaking Capacity
On the primary system diagram, the selected circuit breaker, indicating the circuit breaker model, rated working voltage and rated working current, must also be selected for the breaking capacity of the circuit breaker. With user drawings, the breaking capacity of the circuit breaker is not selected, which makes it difficult for the manufacturer to carry out engineering design. The breaking capacity selection should be based on the system short-circuit parameters. If the manufacturer does not understand the system short-circuit parameters, it is difficult to make the correct choice. There are also some user drawings, regardless of the system short-circuit parameters, blindly select high-break parameters, resulting in unnecessary waste of funds. The correct choice of breaking capacity is very important, not only to ensure safe operation, but also to consider reducing product costs.
