异型储能弹簧在万能式断路器操作机构上的应用
摘要：
本发明涉及异型储能弹簧在万能式断路器操作机构上的应用，在万能式断路器的操作机构中，可根据操作机构不同的弹力需求，选择不同的异型储能弹簧；即：在相同圈数、相同线径、相同剪切模量值、相同自然高度下：当所需弹力较大时，则选用哑铃型弹簧；当所需弹力普通时，则选用圆柱型弹簧；当所需弹力较小时，则选用橄榄型弹簧。所述的异型储能弹簧为哑铃型弹簧或橄榄型弹簧。本发明是在现有技术的基础上，将异型弹簧不同的弹力性能灵活应用到万能式断路器的操作机构中，使操作机构可在相同的安装空间内，根据不同的弹力需求选用不同的弹簧来满足产品的需要。既提高了万能式断路器的质量，也进一步保障了供电线路的畅通。
摘要（英）：

The invention relates to the application of special-shaped energy storage springs to an operating mechanism of an air circuit breaker. In the operating mechanism of the air circuit breaker, the different special-shaped energy storage springs can be selected according to different elasticity requirements of the operating mechanism, namely, on the premise of the same number of turns, the same line diameter, the same shearing modulus value and the same natural height, when large elasticity is needed, the dumbbell-type spring is selected, when common elasticity is needed, the cylindrical spring is selected, and when small elasticity is needed, the olive-type spring is selected. The dumbbell-type spring and the olive-type spring are the special-shaped energy storage springs. On the basis of the prior art, different elasticity properties of the special-shaped springs are flexibly applied to the operating mechanism of the air circuit breaker, and in the same installing space, the different special-shaped energy storage springs can be selected for the operating mechanism according to the different elasticity requirements to meet the requirement of the air circuit breaker. The quality of the air circuit breaker is improved, and smoothness of a power supply line is further ensured.
