YB口-40.5/1.14华式箱变

华式箱变是美式箱变改良的升级版，是一种本土化的预装式变电站。结合了美式箱变小型化以及欧式箱变配置灵活的特点，形成了特有的一种箱式变电站。分别设置变压器室、高压开关室、低压开关室，高压开关室有独立的负荷开关或真空断路器。同美式箱变相比增加了接地开关和避雷器，接地开关与主开关之间有机械联锁，这样可以保证在进行箱变维护时人身的绝对安全。具有安全、可靠、方便、环保等特性。适用于远离居民区的配电工程、风力发电工程、单台箱变装机容量较大的风电和光伏工程。

The Chinese-style box-type substation is an upgraded version of the American-style box-type substation which is a localized prefabricated substation. It combines the compactness of the American-style box-type substation and the flexible configuration of the European-style box-type substation forming a unique type of box-type substation. It includes transformer room, high-voltage switch room and low-voltage switch room. The high-voltage switch room has independent load switches or vacuum circuit breakers. Compared to the American-style box-type substation, it adds a grounding switch and lightning arrester. There is a mechanical interlock between the grounding switch and the main switch to ensure absolute safety of personnel during maintenance. It has the characteristics of safety, reliability, convenience and environmental friendliness. It is suitable for distribution projects, wind power projects, and large-capacity wind and photovoltaic projects located away from residential areas.
