The cabinet is an electronic device designed to organize operational communication and data transmission channels, ensuring the collection and transmission of teleinformation to the server in the amount necessary for the implementation of operationalcontrol of the main equipment of the substation.
Device composition
The cabinet is equipped with relay protection and automatic emergency control command transmission equipment, compensation and alarm panels, uninterruptible power supply source, automatic circuit breakers, sockets, as well as push-button terminals for connecting the device to the AC power circuit and external devices via information communication channels.
Cabinet design
The cabinet is a grounded metal enclosure for two-way maintenance with transparent door at the front and solid door at the back. All metal parts of the device are protected against corrosion. All surfaces of the metal structure are painted with epoxy polyester paint, insulating materials do not support burning.
