Improve the safety of transformers and calmly cope with the peak power consumption in summer

Summer is approaching, and in two months, this year's electricity consumption peak is coming. In summer, the temperature is high, the power consumption is large, and the transformer workload increases, which is prone to excessive operating temperature and overload, which affects the safety of power supply. In recent years, transformer fire accidents have occurred frequently, which has caused huge losses. The open three-dimensional wound core dry-type transformer (hereinafter referred to as open dry-type transformer) has outstanding advantages in safety and reliability, and strong overload capacity, which ensures the safety of power supply during peak power consumption and allows users to use it rest assured.
Strong overload capacity

Resistant to contamination and excellent safety and reliability. The insulation and heat resistance grade of the product is R (C), and the maximum allowable temperature is 220°C. Under the natural cooling mode, it can be overloaded to 110% for a long time, which can meet the power demand of large load fluctuations and long-term high loads.
Flame-proof and explosion-proof

The weight is about 85% less than that of traditional resin insulated dry-type transformers on average, which is more suitable for various places and fields with high fire protection requirements.

Through the combustion test, the open dry cake type coil will self-extinguish when exposed to the fire source, and the flame retardant effect is obvious. However, the traditional epoxy resin coil is ignited by a fire source, is flammable, and burns to produce harmful gases and dense smoke. <img title="WeChat picture_20220416201617m.jpg" src="/Upload/ueditor/images/2022-04-16/WeChat picture_20220416201617m-65991d16-57ec-4120-bfed-d4eea67570eb/gt.jpg" ;Good heat dissipation

The room has ample heat dissipation area, good heat dissipation conditions, low temperature rise of hot spots, and reduces the threat of excessive operating temperature.
Strong short-circuit resistance

distribution, each point on the coil circumference is evenly stressed, and can withstand the current impact force caused by a sudden short circuit, and the upper and lower sides of the iron core are clamped and fixed by triangular frame clamps to further improve the short circuit resistance of the product. The ability of the open dry transformer to withstand short-circuit has been verified in actual use. In December 2020, the distribution box of a community in a city caused the low-voltage cabinet to burn out, resulting in a short-circuit power outage. Current impact, but the product is not damaged, and it is still operating normally.

Peak electricity usage. Haihong Electric is deeply involved in the field of distribution transformers, continues to increase research and development efforts, promotes technological innovation of transformers, provides users with high value-added products and services, and helps build a safe, reliable and efficient power supply system.
