The subject of the invention is an enclosure for secondary distribution modular switchgears, applicable in protecting switchgears both against adverse weather conditions and against unauthorized inspections of high, medium and low voltage switch gear, and also against accidental access by unauthorized persons, or by wild animals and birds. The inventive enclosure containing a base-frame () to which the enclosure walls are attached and which is provided with a roof cover is characterized in that the base frame () is formed by a metal truss and contains two extreme base-frame modules, the left one () and the right one (,) and at least one middle module (and/or () which are connected with one another by means of a pair of permanent connections formed by a socket () and a prong () and fastening and earthing plates ().

Enclosure for secondary distribution modular switchgears

A method for operating a sealed for life compact secondary substation including a transformer, a high voltage side and a ring main unit arranged at the high voltage side and connected to a primary side of a the transformer, a secondary side of the transformer is connected a low voltage switch gear. An enclosure includes watertight material capable of withstanding corrosion at least for a life time of the compact secondary substation. The compact secondary substation is cooled with a cooling system that includes a heat exchanger. The compact secondary substation is protected with an extended arc eliminator. The compact secondary sub-station is connected to a remote control for surveillance and operation, which remote control is communicating with a fault protection equipment.
