Abstract
The utility model relates to an outdoor opening type combined electrical appliance special for high altitude areas. The combined electrical appliance comprises an incoming and outgoing wire interval, a bus interconnection interval, a main transforming interval and a guard interval. Breakers and mutual inductors of the bus interconnection interval, the incoming and outgoing wire interval and the main transforming interval share one set of porcelain insulators, namely wire outlet sleeves, and disconnecting switches and grounding switches of each interval can share one set of insulating pillars, so that the number of the porcelain insulators is reduced. The disconnecting switches, the mutual inductors, lightning arresters, the grounding switches or the like of conventional high-voltage electrical equipment all use individual cement bases. Now the layout of electrical equipment of each interval is improved, and the electrical equipment of each interval can be combined on one underframe, so that the structure is more compact, covering area is reduced, material is saved, and cost is reduced. The outdoor opening type combined electrical appliance has the advantages of small covering area, high safety, and compact layout of the electrical equipment of each interval.
