คุณสมบัติผลิตภัณฑ์
High-voltage tolerance performance is strong, precisely adapted to 20 kV high-voltage environment, load output is balanced, long-term full-load operation does not heat up or trip, the ability to tolerate load fluctuations is outstanding, suitable for industrial regular and high-intensity power consumption scenarios.
Adaptability is flexible, the structure is compact, the sealing protection is solid, it can be adapted to various scenarios such as indoor machine rooms, outdoor open distribution points, etc., can directly connect with Box Type Substation, High And Low Voltage Switchgear, seamlessly integrating, combined with Electric Power Converter to optimize power transmission, without additional interface modifications.
ใช้เคล็ดลับ
Installation requires choosing a flat, ventilated, and dry site, avoiding low-lying, damp, and dusty areas, maintaining a reasonable safe distance from High And Low Voltage Switchgear, with standardized line connections, ordinary construction personnel can complete the installation.
Daily maintenance is simple, no need for dedicated personnel to monitor, regular checks on insulation oil level, oil color, and equipment shell sealing conditions, handle abnormalities in time, no need for professional technology, significantly reducing later maintenance costs.
คําถามและคําตอบทั่วไป
Q: Can the 315 kVA capacity meet the full-scenario power supply requirements after the expansion of medium-sized industrial parks?
A: Absolutely, the capacity precisely adapts to the power load of the park’s expansion, can stably bear all scenarios of power supply, long-term continuous operation without pressure, no need to add additional equipment, effectively reducing the investment cost of expansion, and can also be combined with Combined Photovoltaic Substations to achieve photovoltaic grid connection.
Q: Can the equipment be used in the 20 kV high-voltage environment outdoors for long-term use, and can the sealing and withstand voltage performance be guaranteed?
A: Yes, guaranteed. The sealing process is solid, effectively resisting rain, dust erosion, and the withstand voltage performance has been optimized, long-term outdoor high-voltage operation will not have problems such as moisture, short circuits, or unstable voltage, ensuring operational stability.
Q: Compared with the same specification Oil Immersed Transformer, does this product have more advantages in power grid renovation?
A: Clearly advantageous, interface specifications are universal, can directly integrate into the existing 20 kV high-voltage renovation lines, without large-scale changes to the original power distribution layout, renovation implementation efficiency is high, and load adjustment is flexible, can adapt to the power load requirements of different areas, maintenance costs are lower.
