Summary
This product complies with GB/T17467 high voltage low voltage prefabricated substation "standard". Suitable for city public distribution, street distribution, industrial and mining enterprises, urban construction, residential area, oil wharf, hotels, parks and other construction site, can realize the ring network or terminal type power supply.
Type and meaning
The conditions of use
*Height: 1000m; Ambient temperature: -25~+40℃;
*Temperature: monthly average temperature + 30 degrees, annual average temperature + 20 degrees;
*Relative humidity: the daily average is less than 95%, and the average is less than 90%;
This earthquake level: acceleration level is 0.4m/s, vertical acceleration is 0.15m/s;
9:28 The installation location has no severe impact, no serious pollution and chemical corrosion, and no conductive dust explosion hazard. When it does not meet the normal requirements, please consult with our company to solve it.
The product structure
*Substation includes high-voltage room, transformer room and low-voltage room, which can be arranged in fonts or fonts;
It has terminal, ring or dual power supply mode;
The power supply scheme can be made into single transformer or double transformer;
You can choose oil-immersed power transformers and dry-type power transformers.
. The cabinet is equipped with adequate natural ventilation and heat insulation measures to ensure the normal operation of all electrical equipment, such as
Meet user needs through forced cooling.
This "five prevention" has complete functions, convenient operation and maintenance, and reliable operation;
9:28 Shell material, used for stainless steel, aluminum alloy, cold rolled plate, color steel composite plate, non-metal or a combination of the two, anti-aging, flame-retardant, corrosion-resistant, waterproof, dust-proof, and can be used outdoors for a long time;
It has the advantages of small size, light weight, beautiful external environment and good coordination.
*When using SF6 load switch cabinet, the cabinet has a small volume, which is more suitable for residential construction and street renovation projects.
The high voltage inside the ring main unit can be equipped with an automated terminal unit (RTU) to achieve reliable detection of short circuits and single-phase ground faults, and it has "four remote functions for power distribution automation upgrades."
High pressure side
The high-voltage load switch fuse of prefabricated substation usually adopts combined electric protection, the fuse is fused, three-phase linkage trip and load switch with compressed air, vacuum, sulfur hexafluoride type is optional, and electric operating mechanism can be equipped to realize automation Upgrade; fuse, used for high voltage current fuse, with impactor, reliable breaking capacity. For transformers over 800kVA, you can choose ZN12, ZN28, VS1 and other vacuum circuit breaker protection.
Low pressure side
Low voltage side of the main switch using universal or intelligent type circuit breaker, outlet switch selects new molded case switch has the advantages of small volume, arcing short, outlet flexible; intelligent automatic tracking reactive compensation device, contact and contactless two switching mode for the user to choose.
transformer
Prefabricated substation selection of low loss, oil immersed, sealed S9, S10, S11 series transformer, can also use resin insulation or Nomex insulate environment-friendly dry type transformer, the transformer can be convenient to pass in and out.
