1.American preinstalled type substation YBZ combination
YBZ combination with American type substation, is the high voltage electrical equipment, transformers, low voltage electrical equipment such as combined into compact complete sets of power distribution equipment, used in city mobilize construction, urban and rural construction, the luxurious villa, square park, residential areas and high and new technology industrial park, small and medium-sized factories, mines, oil fields, and temporary construction etc, for receiving and distribution of electric energy in power distribution system.
YBZ combination with American type substation, with complete sets of strong, small size, compact structure, safe and reliable running, convenient maintenance, as well as the characteristics of mobile, compared with the conventional civil type transformer substation, with the capacity of the box-type substation area usually only 1/10 ~ 1/5 for conventional substation, greatly reducing the workload of design and construction, reduce the construction cost in the distribution system, distribution system can be used in the ring network, and also can be used for double power supply or radiation terminal power distribution system, is the urban and rural substation construction and renovation of the new type of complete sets of equipment.
This product conforms to GB/T17467 "pre-loaded with high and low voltage type transformer substation" standards and SD320 box-type substation technical conditions.

4. The product structure characteristics
5. The main technical parameters
Structure features 6.
5.1 this product is composed of high voltage power distribution equipment, transformer and low voltage power distribution equipment connection and become, is divided into three functional compartment, namely, high voltage room, transformer room and low pressure chamber, high and low pressure chamber the function is all ready.High side power supply system, can decorate a ring network, terminal power supply, low electricity double power supply power supply a variety of ways, can also be installed high pressure measuring element, satisfy the requirement of high pressure measurement.Transformer room can sampling S7, integrated, and other low loss oil-immersed transformers and dry-type transformer, transformer room is equipped with leitian forced air cooling system and lighting system, low voltage room according to user requirements can be used panel or tank mounted structure needed for user power supply scheme, power distribution, lighting distribution, no power compensation, power measurement and energy measurement and other functions, meet different requirements of users, and convenient user management and improve the quality for power supply.
5.2 high and low pressure chamber reasonable compact, operation, convenient maintenance, high voltage switch equipment have prevent wrong operation interlock function.Transformer according to user requirements, can be from orbit convenient pass in and out in transformer room door, and transformer room door is equipped with labyrinth ventilation device.Not automatic lighting device of each chamber and the high and low voltage switch equipment selected components reliable performance, simple operation, easy maintenance.Of substation is double layer heat insulation structure, reduce the sunlight radiation effect, eaves around vent, and each function indoor form convection, so that the ventilation and heat dissipation.Base for steel structure, have sufficient strength and rigidity.
5.3 adopt natural ventilation and forced ventilation in two ways, make the ventilation has good performance.Transformer room temperature controller, can automatically control transformer temperature, ensure full load operation of transformer.
The use of 5.4 according to the different environment and conditions of use, can choose different structure forms and materials, meet different application requirements and ensure the normal operation of the transformer substation.Substation shell available nonmetallic materials, the common steel plate, stainless steel plate, aluminum alloy plate, caigang composite panels, such as materials, after processing on the surface of the part or all of it has the condition of long-term outdoor use, to ensure that the anticorrosive, waterproof, dustproof performance, long service life and good appearance.
The basic structure can be roughly divided into:
5.4.1 with landscape type box of nonmetal construction materials or other materials;
5.4.2 with ordinary plates of general type box;
5.4.3 use stainless steel or aluminum alloy with high anti-corrosion type box;
5.4.4 with colored steel composite board insulation type box;
5.4.5 box change to other structure.
Outlet and inlet line of outlet and inlet line of 5.4.6 way for cable commonly, if you have special requirements, available outlet and inlet line of other ways.
7. The performance parameters of the transformer
8. Basic construction requirements
1. The basic hypothesis requires more than 100 kpa
2. The base is located in the terrain is relatively high, around the drainage outward.
3. The cable chamber bottom to water tube side slightly oblique, to avoid water accumulation.
4. The shutters in 150 x300 side welding steel net (1 ox20) ling canthus, shutter frame welding steel claw buried inside the wall outside the window.
5. Foundation construction should be consistent with JGJ16-83 the relevant provisions of the technical specification for electrical design of (building).
6. Main grounding and grounding, the practice is still routinely do grounding line from the cable conduit wiring around the ring network cabinet, after also can extend from one side to decorate grounding, grounding resistance for 4 or less omega.
7. The picture size is recommended.
8. For users can be conveniently into line according to the actual situation in three or four directions set cable pit.
