● Recloser feature
a)Outline of recloser:
The RCW series vacuum recloser is mainly combined with integration terminal, current transformer, permanent magnetic actuator and it’s recloser controller.
b)The recloser tank feature:
The Vacuum recloser tanks are manufactured from 304# grade stainless steel and are powder coated a light grey colour. Whole recloser IP65 protection class, equipped with a auxiliary plug to connect with recloser controller by control cable, Diameter Max22mm, 6 M length (8M for special).
It’s can performance serve more than 20 years long term under heavy duty circumstance.
● Main new advantages of 40.5kV auto recloser
High reliable manual opening device High reliable manual closing deviceVisible ON/OFF indicator IP67 class waterproof plug connector
ROCKWILL ® Supply special design manual closing device technology with own patent, It applied for normal and abnormal situation closing. It’s closing speed(time) comply with IEC62271-100. This function can offset from magnetic actuator fault which when actuator can’t work will cause the major accident.
Primacy incomer terminal (directly connect to interrupter reduce power lost)
(external modular design easy for quality control and maintenance)
Accuracy: ±0.2% Ratio:200/400/800-1
Power frequency withstand of 25kV
and 70 kV for one minute.
Basic insulation level 95 kV and 170 kV
The recloser’s vacuum interrupter insert in an epoxy resin solid pole, and external coated with a high reliable, stable material: Fluorocarbon silicone rubber (γ-trifluoro propyl methyl polysiloxane) With excellent electric insulation, weather resistance, ozone, biological inertia, can be stand under the long-term use in -55 ~ +200 ℃.
Internal Voltage sensors
incorporated within the vacuum
Source-side or Load side
connections Eliminate external
ROCKWILL ® supply special patent modular design mono-stable type magnetic actuator with two coils controlling. It’s the best design for vacuum circuit breaker.
