| Structural characteristics | |
| The structure of metal-enclosed switchgear for the protection class
is IP2X, the main switch cabinet with ZN28A a 10 series vacuum
circuit breaker is equipped with CDl0, CDl7A series electromagnetic
actuator or CTl9B series of spring operating mechanism, isolation
switches GN30-12 Series Rotary disconnecting switch, GN22-10
high-current isolation switch products. The main switch,
disconnecting switch, earthing switch and door chain between the
compulsory mechanical locking million type, consistent with the
"Five Anti" function, with a reasonable structure, safe, reliable,
easy operation, easy maintenance,Meet the national standard
GB3906-91 "3-35kV AC metal enclosed switch equipment" and
international standard lEC62271-200: 2003 requirements. |
