Introduction
Product Overview
KFW-24 outdoor high - voltage sulfur hexafluoride circuit breaker can be equipped with three current transformers 600/5 (600/1), three synthetic zero- sequence current transformers 600/1 (1000/1) and six voltage sensors due to its unique shape and structure, to collect the operating parameters of the distribution network in an all-round way.
Cooperating with outdoor high-voltage fuse (regardless of the bus side or load side of the switch), it can replace the high-voltage circuit breaker, and can be installed on the line or outdoor column, convenient and simple, safe and reliable, and low cost;
This mode is applicable to line T connection, large user prepayment control and capacitor compensation switching. The fuse is used for short circuit protection, which is fast and reliable, and the obvious disconnection point is added;
The switch has the function of phase loss protection to completely isolate the fault zone to prevent the fuse from single- phase disconnection causing long-term phase loss operation;
Overcurrent protection function: according to the load characteristics, the switch can intelligently judge the fault current, only cut off the safety over-limit current, and when a large fault current is detected, the switch will be locked and opened by the fuse, effectively preventing the switch from opening the large current by mistake;
Switching value input function: detect the on-off status, air pressure status, locking status and other switching values of the switch body;
Single-phase grounding protection function: through the detection of zero- sequence current, zero-sequence voltage and power direction, the controller can detect and determine the single-phase grounding fault occurring inside and outside the user boundary;
Over-voltage/under-voltage protection function: protect the system voltage from too high and too low to ensure the voltage quality;
“Three remotes" function: cooperate with the communication channel to carry out remote control, remote measurement and remote signaling tor the switch and realize feeder automation.
