JB/T 51076-1999

Manufacturers and quality inspection agencies of wind turbine generators use this standard to grade and inspect small permanent magnet charging generators. It helps users select appropriate product grades based on key indicators such as output power, efficiency, and reliability. By defining clear grading requirements, the standard promotes product quality improvement and industry standardization.

风力发电机制造商和质检机构使用本标准来对小型永磁充电型发电机进行质量分等和检验。它帮助用户根据输出功率、效率、可靠性等关键指标选择合适等级的产品。该标准通过明确的分等要求，促进了产品质量提升和行业规范化。

This standard JB/T 51076-1999 specifies product quality grading for generators used in wind turbine generator systems, classifying products into three grades: qualified, first-grade, and superior. It covers quality indicators, test methods, and inspection rules, applicable to permanent magnet charging type small wind generators directly driven by the wind rotor. Key technical indicators include output power, efficiency, no-load characteristics, overload, overspeed, short-circuit mechanical strength, starting torque, voltage withstand, enclosure protection level, moisture resistance, low temperature, mold resistance, salt spray resistance, and first failure-free time. The inspection rules adopt the GB/T 2828 sampling scheme and assess products based on defect classification.

本标准JB/T 51076-1999规定了风力发电机组用发电机的产品质量分等，将产品分为合格品、一等品和优等品三个等级。标准涵盖了质量指标、试验方法和检验规则，适用于风轮直接驱动的永磁式充电型小型风力发电机。主要技术指标包括输出功率、效率、空载特性、过载、超速、短路机械强度、起动力矩、耐压、外壳防护等级、防潮、低温、防霉、防盐雾和第一次无故障时间等。检验规则采用GB/T 2828抽样方案，按缺陷分类进行评定。
