Product Description

Recloser RCW⁺

RCW+ type auto recloser is a high performance switchgear sealed with SF6 gas. Which is IP67 class switchgear.

 

RCW+ type auto recloser is DESIGNED For using very important field like key electricity supply points like: gas/oil/mine field, hospital/government/military area, important building etc.

 

RCW+ Auto recloser is equipped with a manual closing solution which is patent design according to the existing brands recloser problem, like ABB, Schneider, Eaton,Siemens, Hubbel,Noja,Jinkang,ect, these listed brand only offer a normal solution recloser which design cant provide with solution for manual closing with elctric power.

RCW+ auto recose is a fast switching switchgear, standard configuured with magnetic actuator and manual closing and opening/locking device, Max 6 voltage sensors.

RCW+ auto recloser is full complied with standard IEC62271-111, ANSI/IEEE C37.60.

RCW+ auto recloser is Offering:

Voltage Rating: 15kV- 38kV

Current Rating: 630A-1250A

Short circuit breaking: 16kA,..25kA

More informations pls go to study RCW+ manual.

· 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 IP67 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 RCW High reliable manual opening device High reliable manual closing device
 

                                            

 

 

Visible 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 sensor (external modular design easy for quality control and maintenance) Accuracy: ±0.5% Ratio:800/1

                                                                                            

 

Internal Voltage sensors incorporated within the vacuum interrupter module. Accuracy: ±0.2 % Voltage Sensor, Ratio:500/1 or 1000/1.

It's equipped with two voltage sensors, one for measuring the voltage of incoming side, and another one for measuring the voltage of outgoing side.

· Creepage Distances of RCW

Description	12kV BIL  75/95kV	15kV BIL  95/110kV	27kV  BIL125/150kV	38kV BIL  170/200kV
Terminal to terminal creepage	600mm	840mm	1250mm	1380mm
Terminal to ground creepage	510mm	760mm	1200mm	1300mm

Apply ANSOFT design the high performance magnetic actuator, high reliable and free maintenance. Through 35,000 times opening reverse excitation test, the demagnetization rate less than 1%.

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.
