原JB515—64《汽车、拖拉机用电气设备技术条件》;JB516—64《汽、,拖拉机用装置电器技术条件》,JB517—64《湿热带汽车、拖拉机用电气设备及装置电器技术条件》三项部标准,随着我国汽车拖拉机工业的发展,各单位生产实践经验的积累以及对产品质量要求的提高,这三项部标准中的部分内容已不能完全适应,有修改的必要。这次修订后的标准中部分指标已有提高。 JB515—《汽车、拖拉机用电气设备基本技术条件》及JB517—《湿热带汽车、拖拉机用电气设备基本技术条件》这两个标准于1976年12月已审查通过,JB515—代替原JB515—64,JB516—64两个标准,JB517—代替原JB517—64。此两项部标准的报批稿正在报批中,请各单位在实际工作中参阅。本标准适用于汽车、拖拉机、摩托车、机动农业机器及汽车、拖拉机型固定式内燃机上的: 电机——发电机、起动机、组合型起动发电机、磁电机及各种直流电动机(通风采、控制机构、两刮、洗涤器、天线和其他类似装置用电机)。 电器——发电机调节器、电磁开关、继电器、点火线圈、分电器、点烟器、电阻 The original JB515-64 “automotive, tractor with the technical conditions of electrical equipment”; JB516-64 “steam ,, tractor use appliances technical conditions”, JB517-64 “wet tropical vehicles, tractors with electrical equipment and electrical equipment,” three Ministry standards, with the development of China’s automobile tractor industry, the accumulation of production experience of various units and the improvement of product quality requirements, some of the three ministries standards can not be fully adapted, there is a need for changes. Some of the indicators in this revised standard have been raised. JB515- “basic technical conditions of electrical equipment for automobiles and tractors” and JB517- “basic technical conditions of electrical equipment for wet-tropical vehicles and tractors” These two standards were reviewed and approved in December 1976, JB515- replaced the original JB515-64, JB516-64 two standards, JB517- instead of the original JB517-64. The approval draft for these two ministries and departments is being submitted for approval. Please refer to all the units for their practical work. This standard applies to cars, tractors, motorcycles, agricultural machinery and agricultural vehicles, tractors fixed internal combustion engine: motor - generator, starter, combined starter generator, magneto and various DC motors (ventilation mining , Control mechanism, two scraper, washer, antenna and other similar devices).
