Aluminum corona rings for gas insulated switchgear (GIS), which can help offer good corona shielding effect of high voltage application. It is easy to operate, convenient to move, and fast to install.
Here let Highv team introduce aluminum corona rings for gas insulated switchgear. Then you will be able to get a clear and a crisp understanding of that.
What Is Gas Insulated Switchgear (GIS)
Since its practical application in the 1960s, Gas Insulated Switchgear (GIS) equipment has been widely used all over the world.
GIS is not only widely used in high voltage and ultra-high voltage fields, but also in UHV fields.
Compared with conventional open substations, GIS has the advantages of compact structure, small footprint, high reliability, flexible configuration, convenient installation, strong safety, strong environmental adaptability, small maintenance workload, and maintenance of its main components. The interval is not less than 20 years.
There are three types of high-voltage power distribution devices.
The first is an air-insulated conventional power distribution device, referred to as AIS. Its busbar is exposed and directly in contact with the air, and the circuit breaker can be a porcelain column or tank type.
The second is a hybrid power distribution device, referred to as H-GIS. The busbar adopts an open type, and the others are sulfur hexafluoride gas insulated switchgear.
The third type is sulfur hexafluoride gas insulated fully enclosed power distribution device. Its English name is GAS INSTULATED SWITCHGEAR, or GIS for short.
Gas Insulated Switchgear (GIS) is a high voltage electrical equipment with high operational reliability, low maintenance workload, and long overhaul period. Its failure rate is only 20%-40% of conventional equipment.
However, Gas Insulated Switchgear (GIS) also has its inherent disadvantages. Due to the leakage of SF6 gas, the infiltration of external moisture, the presence of conductive impurities, the aging of insulators and other factors, it may cause internal flashover failure of the GIS.
The fully sealed structure of GIS makes it difficult to locate and repair the fault, and the repair work is complicated. After the accident, the average power outage repair time is longer than that of conventional equipment, and the power outage range is large, often involving non-faulty components.
Why Do Aluminum Corona Rings Work For Gas Insulated Switchgear (GIS)
High voltage can result in unwanted noise and corona.
Aluminum corona rings are needed to suppress the corona during high voltage testing process.
Aluminum corona rings are common parts in Gas Insulated Switchgear (GIS) systems.
They are easy to operate, convenient to move, and fast to install.
As you know, a lot of corona rings are used in Gas Insulated Switchgear (GIS) which ensures testing project to run more smoothly, efficiently and safely.
When it comes to your Gas Insulated Switchgear (GIS) project, aluminum corona rings from Highv can help you finish all corona shielding solutions.
One of the main factors is the outside diameter of ring body, which have the main influence for potential gradient and corona effect on Gas Insulated Switchgear (GIS). Some end users need more larger diameter rings for their project.
Here we should introduce our processing capabilities of the large outer diameter of aluminum corona rings.
The biggest outer diameter dimension of super aluminum corona ring is up to 16000mm. And pipe inner diameter of aluminum corona ring is 3000mm. Wall thickness of pipe will be from 2.0mm to 10mm.
During the production process, our team will check the sizes frequently and input our Just-in-Time record. This could ensure all corona rings are within the good tolerances.
