Abstract:

In order to meet the construction requirements of intelligent substation,considering the characteristic and using habit of secondary device in prefabricated cabin, it proposes  a new structural form of secondary device called ‘foreside wiring and foreside display’. It makes secondary device’s installing, wiring and operating in front of panel realizable. Using this in cabin, the space of prefabricated cabin can be maximize, the floor space of intelligent substation can be reduced. In that case, this form could impel the miniaturization of intelligent substation.

Key words:

prefabricated cabin, intelligent substation, foreside wiring and foreside display；secondary device
