ZBW series outdoor box combination substation

Product Usage

ZBW series combined (box) substation is a compact power distribution unit composed of high-voltage switchgear, low-voltage switchgear, distribution transformer and electric energy metering equipment. It is used for urban high-rise buildings, urban and rural buildings, residential areas, high-tech development. Areas, small and medium-sized factories, mine oil fields, and temporary construction and electricity. It is used for receiving and distributing electric energy in a power distribution system. It can be used in a power distribution system for a ring power distribution system or a dual power supply or a radiation terminal power distribution system. It is a new type of equipment for the construction and transformation of urban substations.

This series of combined substation meets SD320-92 "Box Type Substation Technical Conditions" and ZBK4001-89 "Combined Type is Station" standard.

Conditions of Use

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

2. Earthquake: The horizontal acceleration of the earthquake is not more than 0.3g;

3. The surrounding air should be free from obvious pollution such as corrosive, flammable gas and water vapor;

4, no frequent and severe vibration;

5. The inclination of the installation site is not more than 3 degrees;

6. When the provisions of this document are exceeded, the user and the manufacturer shall negotiate to resolve it.

Features

1. Adopting three kinds of cooling measures: up and down natural wind convection, horizontal natural wind convection and forced air cooling at the bottom special fan, the temperature rise has a great margin;

2. Light weight, small size and high rigidity;

3, modular: high and low voltage electrical room, transformer room, metering box, capacitor cabinet, each module, can be selected according to user needs;

4, beautiful appearance, low noise, and harmony with the surrounding environment and increase the appearance;

5, powerful, complete facilities, high voltage can meet the ring network power supply, low-voltage room can have 8 power outlets and 4 road lighting outlets;

6, high and low pressure operation corridor up to 1 meter wide, all sides have open doors, operation, maintenance is very convenient;

7. It has strong adaptability and can meet the requirements of different design schemes and different customers. Can be equipped with any kind of 10kV high voltage ring network switchgear; low voltage room has the overall function of low voltage switchgear, and customers can use different types of low voltage switchgear; transformers are equipped with oil pillow or fully sealed or dry Transformer, transformer capacity is 50~1250kVA.
