YB□-H Pad Mounted Transformer
Short Description:
The product equipped the HV load switch and HV fuse in transformer oil .It has common box or separate box with transformer body. Oil tank is enclosed sealed with oil temperature gauge, oil level indicator, pressure gauge , pressure relief valve ,drain oil valve etc to monitor the transformer working conditions.The product has loop feed ,radial feed & power supply type.In order to make this product more suitable for the actual requirements of power grid , we have also introduced plug-in type dry type fuse which fusing do not affect the transformer oil. According to the complexity of low voltage outgoing requirements,YB27 enclosure has standard type, intensive and comprehensive type to make user choice more economic & flexible.
Product details
Product Overview
This product is developed by absorbing the latest advanced technology from abroad and combining it with the actual situation in China. The entire product has the characteristics of small size, easy installation and maintenance, low noise, low loss, anti-theft, strong overload capacity, and full protection. Suitable for newly built residential areas, green belts, parks, stations, hotels, construction sites, airports, and other places.
The YB □ - H series American style prefabricated box type substation is suitable for 10kV ring network power supply, dual power supply or terminal power supply systems, as a substation, metering, compensation control and protection device.
This product meets the following standards: GB/T17467-1998 "High Voltage and Low Voltage Prefabricated Substation" and DL/T537-93 "Technical Conditions for Ordering 6-35kV Box Substation"
Function and Characteristics
◇ Fully insulated, fully sealed, maintenance free, and reliable to ensure personal safety;
◇ Compact structure, with a volume of only 1/3-1/5 of the same capacity of the European transformer, and low height;
◇ Can adopt a split box structure to avoid oil contamination in the transformer oil tank;
◇ High voltage side adopts dual fuse full range protection, greatly reducing costs:
◇ It can be used for both ring networks and terminals, and the cable head can be emergency plugged and unplugged when the load current is 200A;
The box adopts a honeycomb double layered composite board, which has the function of temperature insulation and heat dissipation;
Install an electronic phase loss protector on the low-voltage side, which can quickly disconnect the main incoming switch when abnormal voltage occurs in the system;
High voltage side oil immersed load switch or SF6 load switch can be upgraded electrically, laying the foundation for achieving distribution network automation.
◇ Use oil immersed S9 or better peLXorming S11 series transformers.
