The product adopts a frame structure, welded with steel or assembled from steel plates, the frame is covered with a special paint layer, with strong mechanical properties, weather resistance, corrosion resistance preassembled (box-type) substation as a whole structure, the box is separated into three relatively independent small rooms that are high-voltage room transformer room and low greenhouse room lighting are automatically opened and closed with the door of the preassembled (box-type) There is a heat insulation layer at the top of the substation to prevent condensation caused by the rapid change of temperature in the box in the high temperature and competition area. In order to make the temperature in the box stable, the low-voltage room of the transformer room is equipped with an automatic temperature control device.

THE STRUCTURE OF THE SUBSTATION - 

HIGH-VOLTAGE CHAMBER - Equipped with a high-voltage ring network cabinet, which has a perfect "five-proof" function. The high-voltage switch can choose a sulfur hexaoxide load switch and vacuum circuit breaker. The cabinet has a variety of protection functions such as transformer short circuit and overload.
TRANSFORMER CHAMBER - Equipped with dry or oil-immersed transformers. The box is equipped with a perfect ventilation system, the temperature control value can be set according to needs, and the transformer is equipped with a live interval device to prevent accidental entry during observation.
LOW-VOLTAGE CHAMBER -  Divided into two assembly forms: with corridor type and without corridor type. The indoor can be equipped with metering cabinet, mainline inlet cabinet, outlet cabinet, capacitor cabinet, and contact cabinet (when two transformers are used), with the overall function of low-voltage switchgear. The general measuring cabinet and the main switch are integrated, that is, the upper part of the cabinet is the instrument, the measuring box, and the middle and lower parts are automatic air switches, arresters, and sensors. The capacitor cabinet can be automatically compensated by manual or automatic control. The capacitor reactive power compensation capacity is generally 15-30% of the transformer capacity.

FEATURES

1. Composed of high-voltage switchgear, power transformers, and low-voltage switchgear, with a strong set of space, a small footprint, less investment, convenient installation and maintenance, and beautiful shape, highlighting the concept of green and environmental protection.
2. Built with  BIOSCO technology, it adopts a weld-free assembled structure, which also ensures a beautiful shape.
3. Good surface treatment, strong weather resistance, efficient all-natural ventilation structure.
4. Cabinet modularity design. The cabinet of the intelligent box-type substation adopts a modular design, it has a compact structure, is really safe and reliable to operate, and is easy to install. 

INTELLIGENT DISTRIBUTION SOLUTIONS

Box substations are mainly composed of transformers, high-voltage switchgear, low-voltage distribution equipment, etc., an integrated distribution rooms, box-type transformers are widely used and mostly used in outdoor places, the operating environment is complex and often affected by high temperature, cold, and wind and sand, corrosion, etc., in the process of its operation and maintenance, there will be inconvenient inspection, slow fault response, long processing time, water ingress, fire, human intrusion and other problems. Intelligent box-type substations can be completed by pre-installation and retrofitting, which can greatly improve remote monitoring and fault handling capabilities, improve operational safety and equipment reliability compared with traditional box-type substations.
 

ZHONGHAN CONTROLLER MACHINE
