YBM29 high/low voltage transformer stations Yuzhuang Type
YBM29 uses high pressure / low voltage transformer stations as Yuzhuang Type box change European style is a set-electrical equipment, power transformers equipment portfolio in the tight integration, small size, ease of movement, safe and reliable operation, maintenance convenient, shapes aesthetic characteristics, especially applicable to the urban public distribution, and high-rise buildings, residential areas, industrial and mining enterprises, ports, oil fields, parks, stations, airports, subway, highway, the electricity market. Conditions of use Altitude =1000m Environmental humidity -30 degrees centigrade ~+40 Air temperature does not exceed 90% relative (+25 degrees) Products should be installed without fire, no explosion danger, no serious filthy, non-corrosive gases and intense vibration chemical sites. Beyond the technical requirements, Mail consultation with users and manufacture high
Structural characteristics Box-type change of the basic structure consists of the "eye" font and "materials" font, box-type structure by using channel steel and angle steel welding, a high mechanical strength. Box-type shell material used to produce aluminum alloy plates, excellent corrosion capacity, the overall aesthetic appearance of the painting color coordinated with the surrounding environment, the bottom hanging device designed to provide a great mobile installation transportation convenience. Cover is an independent pressure room, transformer room and low voltage room, lighting the room with the door closed to shut automatically. - Equipped with high-pressure part of the indoor network switching equipment may be based on user needs to use pressurised gas - and vacuum-load switches, and a "5 -" function, when used by Stream-satisfied, and when a similar terminal Rongduan, load automatically at the beginning of sub-gates, avoid missing as a result of operational failures caused. Transformer room available natural ventilation and automatic control forced air heat release devices, and automatic control of the temperature change the system features effectively lower box temperature control to meet operational requirements, according to user requirements have also been used against Ninglu devices. Youjin be dry-type transformers or transformer supplies, Youjin Type transformers can choose a non-oil and oil-sealed pillow two. Low voltage equipment room at the beginning of a low-voltage sets the overall function for users to select, high and low voltage opening cabinets are assembled by using quality deficit with strong defense capability, high-pressure, low-voltage cable into the project generally, the special needs of high-voltage overhead can choose into line.

A typical programme,
Operation and maintenance
Operation and maintenance of high voltage switches use, beginning with the installation of high use brochures. Low voltage electrical equipment, air circuit breakers, with the repeated Hop, hours after the operation, would have a main Chutou local chain burns and carbon substances to Chutou contact resistance is increasing, air trip should be regularly maintained by the use of descriptions Electricity metering modules for regular check by the electricity sector Regular observation of the operation of transformers, cooling systems are normal, temperature-controlled automatic Kam whether normal or coil transformers upper Youwen temperature (referring to the dry-type transformers) are normal. Equipment operation, maintenance should be qualified electrical professionals. Installation A. Cartons change based reference map Mail manufacturers under the programme to provide, as required, since more users can also design, subject to consultation with the manufacturers B. Changes in the boxes and around the side of the foundation laid very good grounding, transformer earthing can share with mine grounded a grounded system, lead to a change in the basic platform at the wiring should not be less than two, and that earthing resistance R=4 C. Box-type change between the cracks in the foundation and cement slurry mind closed to prevent flood water from entering the cable room |
