Combined Transformer Box Type Substation
⇒ PRODUCT DESCRIPTION
YB type compact substations and says Europe type box change, GB17467-1998 product conforms to the high and low voltage substation and IEC1330 preinstalled type, such as a new standard for power distribution equipment, it than conventional civil substation has many advantages. Because of its small volume, cover an area of an area small, compact structure, easy to move, thus greatly shorten the construction period and covers an area of, also reduced the infrastructure expenses. Meanwhile, the box-type converting stations on site installation is simple, rapid, equipment maintenance simple power substation, without special, especially it can further load centers, to improve the quality of power supply reduce power loss, enhance the reliability and power of distribution network re-election are important. Complete electricity transformation change box, the distribution, transmission, measurement, compensation, system control, protection and communications functions.
By high-voltage switchgear YB engineering-type substation, low-voltage distribution screen, distribution transformer and shell with a combination of four sections, high-voltage air load switch, transformer for dry type transformer or oil-immersed transformer Cabinet adopted good insulation ventilation structure, appearance beautiful generous, heat insulation performance is good, and the upper body sets, outdoor ventilated for every shot ducts and high or low voltage transformer room temperature can reduce the room caused to a minimum The cabinet to furnish temperature control forced ventilation device and automatic temperature control device sun. Each independent units installed perfect control, protection, charged display and lighting system.
Compact Substations Series (European Box Transformer) Application Scope
Applicable to below 35KV voltage, etc, the main transformer capacity 5000KVA and below small substations, widely used in substation halting city industry substation, consumers 10KV ring net system, rural 35KV substation and so on.
Compact Substations Series (European Box Transformer) Main Function
Complete electricity transformation, distribute, transmit, measurement, compensation, the system of control, protection and communications functions.
Compact Substations Series (European Box Transformer) Main Features
Will the primary and secondary equipment installed a portable sealed, temperature control, anti-corrosion moisture-proof anti-rust the cabinet, arriving at the just installed in cement basis. Has less investment, construction period is short, covers an area of less, easy and harmonious environment etc. Characteristics.
