随着社会、经济的不断发展,工程建设的复杂程度的加大,用户对开关设备小型化、免维护、智能化的要求越来越高。中压领域尤其是在35kV电压等级,常规的以空气为绝缘介质的开关柜普遍体积较大(柜宽不小于1.2m,体积一般不小于7m3),重量较重(一般不小于2t),操作困难,尤其不能满足在?
With the continuous development of society and economy, the complexity of engineering construction is increasing, and users are increasingly demanding the miniaturization, maintenance-free and intelligentization of switchgear. In the field of medium voltage, especially at the voltage level of 35kV, conventional air-insulated switchgears are generally large in size (the cabinet width is not less than 1.2m and the volume is not less than 7m3 in general), heavy weight (generally not less than 2t), operation Difficulties, in particular, can not be satisfied?
