Product Description
The prefabricated substation (European-style box-type transformer) is a complete set of power distribution equipment. It is composed of high-voltage switchgear, distribution transformers, low-voltage switchgear, electric energy metering equipment, reactive power compensation equipment, auxiliary equipment and connecting parts, according to a certain wiring diagram to be connected in one of the factory indoor, outdoor compact type distribution equipment.
All components are pre-assembled in one or several casings to transfer electrical energy from the high-voltage system to the low-voltage system. Prefabricated substation can penetrate deep into the load center and transfer with the load center.
We offer a variety of standard designs and configurations, and also can customize for special designs and options.
Main Characteristics
1. Compact structure, small size, removable.
2. Power supply safety and reliability: can provide perfect mechanical or electrical linkage, meet the requirement of "five defense", and ensure the safety of the person.
3. Enclosure material is various, design beautiful, under the premise that guarantee the power supply reliability, by selecting the box-type substation shell color thus easy to harmony with the surrounding environment, especially suitable for urban construction.
4. The transformer is mainly ventilated with natural ventilation, and when the temperature of the transformer room exceeds the set temperature, the axial fan on the top automatically starts to control the temperature of the transformer room.
5. The pre-installed transformer substation can be customized according to the user's requirement so the selection scope is large and the market ability is strong.
6. High degree of automation. Protection system using microcomputer integrated substation automation devices, which can realize "four control" of telemetry, remote communication, remote control, remote regulating. Each unit has independent operation function and complete relay protection function. The operation parameters can be set from remote distance to control the humidity and temperature of the enclosure and the smoke alarm meeting the requirements of the unattended. Image remote monitoring can be implemented as needed.
Advantages
1. Compact structure, small size and removable.
2. Safe and reliable operation.
3. Easy for maintenance.
Applications
1. Construction sites, oil fields, ports, terminals,
2. High-rise building.
3. Highways, subways, airports, residential areas.
Service Environment
1. Ambient temperature: Maximum +40ºC, Minimum -25ºC
2. Altitude: less than 1000 meters.
3. Seismic level: less than 3m/s2 at horizontal direction and less than 1.5m/s2 at vertical direction.
4. Installation environment: No obvious and heavy pollution, no explosive and corrosive gas and dust, with good air ventilation and no severe vibration and shock.
(Note: If the application environment is different from the above standard conditions, please contact for customized designs.)
Compact structure, small size, safe and reliable operation, easy for maintenance and removable.
