SOLID INSUL ATED
RING MAIN UNIT

Overview
XGN □ -12 (CVF) solid insulated ring MAIN UNIT switchgear is a new generation of environmentally friendly solid insulated ring network cabinet
developed by the company. It is mainly composed of three functional units, namely V unit (breaker unit), C unit (load switch), F unit (combined electric
unit), each unit can be used alone or freely, and its structure is divided into intelligent control instruments. The chamber, the operating mechanism
and the primary part, the instrument room can be equipped with a microcomputer protection (controller), the mechanism is a special elastic operation
mechanism, and the APG automatic gel process is used in one part, and the isolation switch and the arc extinguishing chamber are completely sealed
in the epoxy resin. There are special joints and busbars. The design switch of the arc extinguishing chamber uses the special copper-chromium contact
material, the R-type vertical magnetic field contact, and the complete primary sealing process. The arc extinguishing chamber breaks the short-circuit
current capability, stability, electrical life and temperature. The rise and insulation levels are significantly improved compared to the previous arc-
extinguishing chamber (copper-aluminum contact material, cup-shaped longitudinal magnetic field contact structure, and incomplete primary sealing
process). The operating mechanism adopts a bullet-operating mechanism integrated with the switch, that is, the isolating switch and the main switch-
operating mechanism are integrated, which can easily realize interlocking, and has fewer mechanism parts, reduces unnecessary transmission links, and
has high reliability, and Electric operation can be added according to user needs.
Fixed insulation fully enclosed switchgear: It is made of solid insulating material as the main insulating medium and conductive connection, isolation
switch, grounding switch, main busbar, branch busbar, etc. The main conductive loop is single or combined and packaged with solid insulating medium
for one or several Fully insulated, fully sealed modules with certain functions that can be combined or expanded again.
The three-station mechanism uses a mid-spring design that has the function of switching and closing the load current, and can also be operated manually and
electrically.
According to the functional units in the system, they are classified into: inlet cabinet, outlet cabinet, female cabinet, metering cabinet, PT cabinet, lifting cabinet, etc., which are
indicated by the wiring scheme number;
According to the main switch component type, it is divided into: load switch cabinet, load switch-fuse combination electric cabinet, circuit breaker cabinet and isolation switch
cabinet, etc., respectively, F (fuse combination electric appliance), V (circuit breaker), C (load Switch) and so on.
