Outdoor VCB/ACR Product Description
11kV 12kV 630A Vacuum Auto Recloser Circuit Breaker
Applicable place: (Suitable for the places frequently operated with rural power grid)
1. Industrial.
2. Power stations.
3. Substations.
It can avoid aerial without the time, protect power, power fault accident narrow scope, shorten the time, protect power users of the main safety operation.
Recloser Advantages
1. Equipped with vacuum arcing chamber of the column in vacuum circuit breaker.
2. Circuit breaker using fully closed structure, sealed performance is good, help to improve the moistureproof, prevent condensation performance;

3. It can detect the limit value and judge the milliampere zero sequence current, and alternate with the short-circuit fault current to automatically cut off a single ground fault;
4. It has fault detection function, protection control function and communication function;
5. The operation is sealed inside the switch, which can effectively avoid the rusting of the mechanism caused by the outdoor environment of the switch for a long time.
6. The operation is novel, simple, reliable, small, and the mechanical life can reach 10000 times.

Overview

RVB type outdoor vacuum circuit breaker covering 12kV up to 36kV range for transformer substation and switch station using.
The current rating: 630A,….2500A, short circuit breaking current rating: 25kA,…40kA.
Its perfect design for instead of traditional type like OHB,VBF,3AF,ZW7,ZW30,ZW39,ZW37…etc.
More light, compact, reliable, and friend-enviromentaDeveloped RVB-40.5 series of outdoor vacuum circuit breaker using modern processing technology and computer-aided design techniques,
combined with the latest generation of spring bodies and the advantages of a permanent institution. Its pursuit of high reliability,
easy to maintain design concepts to create a generation of superior product, is the most reliable electric power system the best option.
RVB-40.5series of switches of the main use software and solidwork designed with the overall nice, safe and reliable.
RVB-40.5Series switches have a variety of styles to choose from:
RVB-40.5Nordinary outdoor vacuum circuit breakers, spring actuator come standard with mechanical life of 20,000 times.
All series switches meet the following criteria:
ANSI/IEEE C37.60/IEC 62271-100( GB1984-2003 China standard)
GBT11022-1999 China Standard
IEC 60255-11
IEC 60255-21-1 Class I
IEC 60255-21-2 Class I
IEC 60255-21-3 Class I
IEC 60255-22-1 Class III
IEC 60255-22-2 Class IV
IEC 60255-22-3 Class III
IEC 60255-22-4 Class IV
RVB-40.5 Spring type VCB main characteristics
Reliable manual opening device
Reliable and labor-saving manual closing
Visible sub-closing indicator
IP64 protection class plug connector

Description:

Offering a unique design of the manual switch on technology to meet the state of conventional and unconventional features of the Closing. Its speed to meet IEC62271-100 and similar GB1984-2003 standard requirements.
The emergence of the technology to make up for the permanent institutions and agencies in their respective spring shortcomings, is a new generation of high-performance power switching distinguishing features.
Primary busbar terminal (direct overlap with the interrupter to reduce unnecessary power losses)
Vacuum interrupter (APG process using solid-solid insulating sealing technology, plus silicone rubber molding compound technology to improve the overall switch weather performance)
Extensible outlet pipe (plus modular design, which will help insulation margin of certainty and product interchangeability requirements)
RVB series vacuum switch rejection of the traditional switch design concepts, will absorb some of the advanced design concepts, simplifying the overall transmission mode switch,
greatly reducing the transmission power loss of this switch makes switching better overall performance and longer life.
Makes the whole body switches provide a higher life expectancy, more stable mechanical properties.
RVB-40.5N provide up to 25,000 times the mechanical operation of life, institutions 20,000 times the number of maintenance-free operation.
RVB-40.5Mto provide up to 100,000 times the mechanical operation of life
