High voltage electrical equipment distribution device also called high voltage electrical equipment power distribution cabinet.
High voltage electrical equipment distribution device is composed of supply complete sets of manufacturing equipment, arrived at the scene and assembly of high-voltage electrical distribution equipment.
It will be the main electrical circuit is divided into a plurality of units, each unit is a loop, each unit circuit breaker, isolating switch, current transformer, voltage transformer, as well as protection, control, measurement and other equipment assembly in a whole cabinet ( usually called side or a high voltage electrical equipment switch cabinet ), there are a number of high voltage electrical equipment switch cabinet in power plant, or power distribution substation is mounted upon the composition of the power device is called a complete set of power distribution equipment.
High voltage electrical equipment distribution device according to its characteristics into the metal enclosed, metal enclosed armoured type, metal enclosed box and SF6enclosed combined electrical appliance and so on; according to the circuit breaker mounting mode is divided into fixed and hand cart type; according to the installation place for outdoor and indoor type; according to the cabinet structure is divided into open type and closed.
Switch cabinet has a" five prevention" linkage function, preventing classification error, and circuit breakers, and pulling the on-load isolating knife switch, an electric closing earthing knife gate, preventing earth lead to close the breaker, preventing misgoing into electrified interval chain function.
" Five prevention" linkage function often adopts the circuit breaker, isolating switch, earthing switch and cabinet door between mandatory mechanical latching means or an electromagnetic lock mode. High voltage electrical equipment complete sets of equipment ( high-voltage electrical equipment power distribution cabinet ) refers to a voltage of 3kV and above,
The frequency of 50Hz and below the power system to run indoor and outdoor AC switch equipment.
