Product description

Parameters

The main purpose
YBFKN12- 27 5ID/630- 20 indoor AC high voltage load switch (hereinafter referred to as YBRKNI2 -27 5ID load switch) is a phase AC high voltage switchgear with a rated voltage of 27.5kW and a rated frequency of 50Hz. Used to switch load current. closed loop current. No-load transformer and cable charging current, close-circuit short-circuit current, etc., load switch equipped with grounding switch. Can withstand short-circuit current.
YBFKNI2--27.5IDV/630- 20 type indoor AC high-voltage load switch-fuse combination (hereinafter referred to as FKNI2--27.5IRD) combination is a YBFKNI2--27.5ID)0 load switch and S port LAJ- 40.5XRNT port-40.5) Indoor high-voltage switchgear combined with high-voltage current-limiting circuit breaker. It can reliably break any current up to the rated short-circuit breaking current, the load switch breaks the working current, the fuse breaks the circuit current, and it can jointly break any overcurrent between the working current and the full circuit current, and at the same time the filling is broken. The breaker opens the load switch by striking the burst.

Scope of application
YBFKN12- -27 .5ID)I bipolar load switch and YBFKNI2 -27 5IRDI bipolar combined electrical appliance are mainly used for load control and short circuit protection in power distribution facilities at the front end of 27.5kV transformers in railway traction network. Because the protective effect of combined electrical appliances on electrical equipment such as transformers is more reliable than that of circuit breakers, it can be used as dry-type transformers high temperature tripping, heavy gas tripping protection, and tripping protection for door opening when electrified.
