A modular transformer for wind power generation is a transformer that integrates the high-voltage step-up transformer core, switchgear, fuses, tap changers, and associated auxiliary equipment into a single unit. Both the high-voltage switchgear and fuses are housed within the oil tank, resulting in a compact overall footprint. Its structural configuration is similar to the pad-mounted transformers introduced from the United States in the 1990s, and it is commonly referred to in the industry as “wind-power American-style transformer.”
光伏发电作为一种清洁的能源生产方式，在国内外得到迅速的发展，Z口S-ZG-口/口系列组合式变压器正是为满足日益增长的光伏发电的供电要求，在公司生产35KV组合式变压器基础上，消化吸收国内外的先进技术结合国内需求自行开发的系列产品。该产品是将变压器、负荷开关、高压熔断器安装在变压器的箱体内，利用变压器的绝缘油作为整个产品的绝缘和散热介质，油箱采用全密封结构，具有体积小、重量轻，安装方便等优点。光伏发电用组合式变压器主要分为双绕组和双分裂两种。其中轴向双分裂高压采用轴向分段绕制。
The 12 kV load-break switch-type cable distribution box is one of our company’s series of cable distribution boxes. It is developed by integrating switching equipment into the conventional distribution box, which facilitates maintenance and control, reduces the area affected by power outages during maintenance, and makes it an ideal choice for modern cable distribution applications. The enclosure is fabricated from 2 mm-thick imported stainless steel plate (or, upon customer request, from cold-rolled steel), with a well-designed structure that ensures independent compartments for each functional unit, separated by partitions to prevent mutual interference. The distribution box is equipped with a “five-protection interlocking” mechanism to prevent misoperation.
The high-voltage automatic reactive power compensation device, based on the grid and load conditions of the 10 kV supply busbar, uses a control system to automatically switch capacitor banks in response to changes in reactive power demand, thereby achieving automatic reactive power compensation. This device provides automatic reactive power compensation, continuously tracks variations in reactive load, switches capacitor banks as needed, improves the power factor, and enhances power quality; it also features harmonic suppression, with series reactors that can be configured according to site-specific harmonic conditions to form LC resonant circuits for harmonic filtering; furthermore, it offers comprehensive protection for the capacitor bank, including overvoltage protection, undervoltage protection, overcurrent protection, zero-sequence voltage protection, and protection against unbalanced voltages in individual capacitor branches.
