Advantages of Vacuum Interrupter for Recloser

Increased reliability - The highest creep distance among the recloser poles on the market ensures long-term performance in any environment.

Unparalleled performance - The HCEP (Hydrophobic Cycloaliphatic Epoxy) material of the poles provides the best insulation for outdoor use, shedding water and debris, thus reducing the probability of flashovers even in heavily polluted areas.

Simple, fast and safe maintenance as all the electronics are in the low-voltage range, eliminating the need for a bucket truck to isolate potentials to service electronics.

Easy integration with ABB Relion® protection RER615 2.0, capable of programming grid applications.

Solid dielectric recloser: ABB vacuum interrupters and sensors embedded in each recloser pole.

Application of Reclosers

 

The basic function of the recloser, which should minimize the mains outage time indicator, is to provide repeated cycles of auto-reclosure after the time intervals set in the control module. In addition to increasing the reliability of power supply as the main technical effect of using reclosers in accordance with the established indexes such as SAIFI (System Average Interruption Frequency Index), SAIDI (System Average Interruption Duration Index) and MAIFI (Momentary Average Interruption Frequency Index), reclosers can be used as a sectionalizer, automated load-break switch or outdoor protection device in substation and distributed energy networks. Flexible functional settings for the specific power infrastructure makes the vacuum recloser a universal solution in medium voltage networks with rated voltages of up to 38kV.

Feeder application: Radial Line Recloser

When a recloser is installed on a radial feeder it automatically clears transient faults and isolates permanent faults. More than one recloser can be installed on a feeder to isolate faults selectively and ensure fewer customers are affected.

Feeder application: Loop Recloser

The main function of the solution in which reclosers are used in the automatic distribution system is to restore of power supply to consumers' points in the shortest possible time. To configure automatic restoration system using more than 3 ACR connected to each other.

Places where a recloser joins feeders together are called recloser loop tie points. The reclosers located closest to the substation is named as the Feeder ACRs. Between Feeder Tie ACR and Feeder ACRs are installed and Mid-Point reclosers

Substation Application

Reclosers can be used to quickly build cost-effective unmanned outdoor substations. A recloser provides full protection and automation functionality required at the substations. The devices are not only installed at newly designed substations, but are also used to replace obsolete switching devices at existing substations.

Distributed Generation Interconnection

The transition from centralized to decentralized power supply systems for consumers in local areas, allowing the use of distributed renewable power sources, called Distributed Generation (DG) - such as as solar power generation, hydro generation, wind power generation and capacity generation (natural gas) etc.

 

Operation of Vacuum Circuit Breakers

Power Preparation
Ensure that the circuit breaker is connected to the power source, checking electrical connections and grounding conditions.

 

Control Signal
Issue the closing or opening control signal as needed, typically by an automated system or a manual operation panel.

Closing

When operating the button or switch, the closing mechanism of the breaker will close the contactor, allowing current to pass through.

Opening

When it is necessary to cut off the current, send the opening signal, and the breaker will quickly open the contactor, cutting off the circuit.

Status Indication

Observe the indicator lights or instruments to confirm the working status of the breaker.

Ensure safety during operation and that the vacuum circuit breaker equipment is in an appropriate working environment.

FAQ

 
 

Q: What is the purpose of a vacuum interrupter?

A: A vacuum interrupter stops the flow of AC power between a pair of electrical contacts using the high vacuum within which they are enclosed.

Q: What is the structure of a vacuum interrupter?

A: The vacuum interrupter is a pair of separable contacts (primary contacts), enclosed in a vacuum-tight envelope. The envelope itself is a ceramic material, with a metal end plate brazed to each end. The metal plates seal the ends and provide support for the parts inside.

Q: What material is vacuum interrupter?

A: The vacuum interrupter is a pair of separable contacts (primary contacts), enclosed in a vacuum-tight envelope. The envelope itself is a ceramic material, with a metal end plate brazed to each end. The metal plates seal the ends and provide support for the parts inside.

Q: Where do we use vacuum circuit breaker?

A: VCBs have many applications, and various industries can use them, including power plants, commercial and manufacturing buildings and industrial plants. They work well in both medium- and high-voltage systems and are typically considered the most reliable option.

Q: Can your factory produce according to customer's requirements?
