Integrated pre-assembled box-type substation

This series of products is a kind of high-voltage switchgear, distribution transformer low-voltage switchgear, power metering equipment and reactive power compensation device, etc. According to a certain wiring scheme combined into a compact set of power distribution equipment, used in urban high-rise buildings, urban and rural buildings, residential neighborhoods, high-tech development zones, small and medium-sized factories, mines and oilfields, as well as temporary construction of electricity, as a line and distribution of electrical energy. It is a kind of developing equipment with high degree of integration, factory pre-installation, energy-saving and land-saving. Compared with the conventional substation, it occupies 1/20 of the land area, 1/7 of the construction period, and 1/2 of the investment. small size covers a small area, short installation period, reliable operation, small investment, and easy to harmonize with the environment of the district. It can shorten the length of low-voltage cable, reduce line loss, and also reduce the cost of power supply support. It is a new generation of energy-saving and carbon-reducing products.

Model Meaning

Product Features
Fully functional and reliable
Capable of cutting off short-circuit and load currents, and capable of full-range current protection. High-voltage section: ring network (including dual power supply), terminal, with high-voltage metering and other power supply options, with the traditional civil substation functions.
Less investment, less land occupation, easy installation, quick effect.
Save money: less capital investment than traditional civil substation; save land: small volume, about 1/3 of the volume of the same capacity distribution room or smaller; save time: normal product delivery time of 15 days, the site is easy to install, the scene only need to connect the inlet and outlet cables can be.
Good safety
Adopting fully enclosed design, the product shell is reliably grounded, and there is no point part on the outer surface, so there is no need for insulation distance, which reliably ensures personal safety.

Structural features
● This product consists of high-voltage power distribution device, transformer, and low-voltage power distribution device connected into three functional compartments, namely, high-voltage room, transformer room and low-voltage room, high and low-voltage room is fully functional. High-voltage primary power supply system can be arranged into a ring network power supply, mid-range power supply, dual-source power supply and other power supply modes, but also can be installed high-voltage metering components to meet the requirements of high-voltage metering of oil-immersed transformer S13 (11) and dry-type transformers, energy saving and carbon reduction, the transformer room is equipped with self-starting forced air-cooling system and lighting system, low-voltage room according to customer requirements can be used in panels and cabinets mounted structure to form the required power supply scheme, there are Power distribution, lighting distribution, no power compensation, power metering and power measurement and other functions, to meet the different requirements of customers, and to facilitate the user's power supply management and improve the quality of power supply.
● The high-voltage room has a compact and reasonable structure, and has a comprehensive anti-misoperation chain function. The transformer room can be equipped with rails that can be easily accessed from both sides of the high-voltage room. Each room has automatic lighting device, in addition to high and low voltage room selected all the components of reliable performance, easy to operate, so that the product is safe and reliable, easy to operate and maintain.
● Adopting natural ventilation and forced ventilation in two ways, so that the ventilation and cooling is good. Transformer and low voltage room have ventilation channel, exhaust fan has temperature control device, according to the set temperature can automatically start and close, to ensure that the transformer is running at full load.... The shell is non-metallic structure, beautiful appearance, good heat insulation performance. The base is channel steel structure with sufficient strength and rigidity.

Conditions of use
● Altitude not exceeding 1000m above sea level.
● The maximum ambient temperature does not exceed +40℃, the minimum temperature does not fall below -25℃, and the average temperature of the period within 24 hours does not exceed +35℃.
