·Overview

YBW-24 box-type substation (YBW-24 combined substation) is a compact substation composed of high-voltage switchgear, power transformer, low-voltage switchgear, electric energy metering equipment and power compensation device assembled in one or several boxes. electrical devices. This product is divided into two series: open type and closed type. The high-voltage part of the closed box-type transformer adopts SF6 ring network power supply unit. This product has the characteristics of strong completeness, short installation period, small floor space, low investment, safe and reliable operation, beautiful appearance, and easy coordination with the surrounding environment. This product uses SC series epoxy resin dry-type transformers (at the same time, oil-immersed power transformers can also be used) to achieve oil-free power supply.

YBW-24 box-type substation is suitable for high-rise buildings, residential areas, factories and mines, street lights and other places, especially for temporary construction. This product can use a microprocessor to monitor temperature, humidity, and condensation according to user needs. It has fault monitoring and memory functions. It has current, voltage, and power display and recording functions, and has a communication interface to network with the central computer and can be connected remotely. Distance control.

·Operating environment conditions

1. The altitude does not exceed 2000mm;

2. The ambient air temperature should not be higher than +500C and not lower than -300C;

3. Wind pressure does not exceed 700Pa (equivalent to wind speed of 34m/s);

4. The horizontal acceleration of the earthquake does not exceed 0.4m/s2, and the vertical acceleration does not exceed 0.2m/s2;

5. In places where there is no risk of fire or explosion, serious pollution, chemical corrosion and severe vibration, the inclination shall not be greater than 30°.

Note: When the above usage conditions cannot meet the usage requirements, the user shall negotiate with the manufacturer.

product structure

1. The product structure is divided into three independent parts, namely high-voltage room, transformer room and low-voltage room. According to the layout of the product, it can be divided into two structural forms: mesh-shaped and vertical-shaped. Generally, the mesh-shaped structure is used, and the vertical-shaped structure is used when there are many low-voltage circuits.
