คำอธิบาย
125 kVA 20 kV Oil-immersed Transformer
ภาพรวมหลัก
This transformer is suitable for 20 kV high-voltage scenarios, with a capacity of 125 kVA. It is mainly used in small and medium-sized industrial parks, outdoor distribution points, and power supply for photovoltaic systems. No complex renovations are required. It can be used directly upon arrival. It combines practicality and durability to meet the basic requirements of high-voltage distribution.
คุณสมบัติผลิตภัณฑ์
Compatible with 20 kV high-voltage environment, stable operation, no voltage fluctuations, no frequent adjustments during daily use, convenient and stress-free.
Moderate in size, easy to install, can be flexibly deployed whether outdoors or in factories, without occupying too much space.
Compatible with Box Type Substation (Box-type Transformer Station), High And Low Voltage Switchgear (High and Low Voltage Switchgear), and used with Electric Power Converter (Electric Power Converter). No additional interface modifications are required. It can directly connect to existing distribution lines.
เคล็ดลับสําหรับการใช้งาน
When installing, find a flat surface, ensure proper line connection, avoid poor contact, and no professional construction team is needed. Ordinary people can also operate.
Daily maintenance is not complex. Occasionally check the oil level. As long as the oil color is clear and there is no odor, it will not affect usage.
Avoid severe collisions to prevent damage to the sealing structure, which may affect the stability of high-voltage operation.
Common Problems
Q: Can this transformer meet the entire power supply requirements of small and medium-sized parks?
A: Absolutely, the 125 kVA capacity is just suitable for the daily power supply of small and medium-sized parks and factories. No additional equipment is needed. The operation is stable and uninterrupted.
Q: Will outdoor installation be affected by wind and sun exposure?
A: No, the equipment is protected by sealing, can resist wind, sun exposure, and rain erosion. Long-term outdoor use will not cause faults and does not require frequent maintenance.
Q: Without professional operation knowledge, can it be maintained by oneself?
A: Yes, daily maintenance only requires checking the oil level and the appearance of the equipment. If there is insufficient oil level or abnormal oil color, simply replenish or replace it. No professional skills are required. The operation is simple.
