RCW(N) type economical auto recloser is a class simple combination switchgear which is Solid insulated with vacuum interrupting technology, with silicone rubber coating and simple relay protection and equipped with a spring mechanism ahieve auto closing function under operating sequence O-0.5-CO-15S-CO.

This type aut recloser is basic version auto recloser, which is equipped with 3 current transformer and spring mechanism and economic controller.

RCW(N) type auto recloser is exact terminal switchgear for using at position front of distribution transformer(or secondary substation power transformer purpose of protection breaker)some similar like sectionalizer or breaker with relay protection.

Thus,RCW(N) type auto recloser is Actualy a normal motroized type spring mechanism vacuum circuit breaker with manual and motorized opening/closing device. Its suitable for using on simple purpose grid as a switching and key point protectio breaker.

RCW(N) type auto recloser is very compact design switchgear, which is widely using on worldwide, the voltage rating range from 6kV up to 40.5kV.Insulation level at BIL 200kV max. The current rating range from 630A, up to 1250kA, 25kA.

● 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● Main new advantages of RCW

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)
Current transformer
(external modular design easy for quality control and maintenance)
Accuracy: ±0.2% Ratio:200/400/800-1
Capacity:2.5VA/5VA
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
interrupter module
Source-side or Load side
connections Eliminate external
voltage-sensing PTs

 

 

Note:

ROCKWILL ® supply special patent modular design mono-stable type magnetic actuator with two coils controlling. It’s the best design for vacuum circuit breaker.
