MV Air insulated Switchgear Panel Descriptions:
· Ring network cabinets are generally divided into two types: air insulation and SF6 insulation. They are used for switching load currents, breaking short-circuit currents and transformer no-load currents, and charging currents for overhead lines and cable lines at a certain distance. They play a role in control and protection. Important switchgear for grid power supply and terminal power supply. In the cabinet, the load switch with air insulation mainly includes gas-generating type, compressed air type, and vacuum type. The load switch with SF6 insulation is SF6 type. Since SF6 gas is enclosed in the shell, the partition fracture formed by it is invisible. The load switch in the ring network cabinet generally requires three stations, that is, to cut off the load, isolate the circuit, and be reliably grounded. The gas generating type, compressed gas type and SF6 type load switch can easily realize three positions, but the vacuum interrupter can only be disconnected and cannot be isolated, so the general vacuum load ring network switch cabinet is equipped with an isolation switch before the load switch to Form an isolation fracture.
· MV switchgear，Flexible combination, reliability, availability and economy are the attributes that make it easy for our clients in industry and utilities to decide in favor of primary gas insulated switchgear products from the ZX series. Together with complete conventional solutions, the use of digital protection and control technology, sensor systems and plug-in connections make ZX systems fit for the future.
MV Air insulated Switchgear Panel Advantage:
· First of all, due to the use of compressed gas with excellent performance, the insulation performance is greatly improved. The insulation performance of compressed gas is 2∽3 times that of air, and as the voltage level increases, the advantages become more obvious. Due to this advantage, it is convenient to design a smaller cabinet size, which is conducive to the development of miniaturization;
· Secondly, due to the use of compressed gas with excellent performance, sometimes the arc extinguishing performance can be improved;
· Again, due to the airtight structure, it should not be affected by the external environment (such as condensation, pollution, small animals and chemicals, etc.), and can be used in harsh places. For example, when the Elbe River in Germany flooded in 2002, the inflatable tank was partially flooded, but the power supply was restored quickly. This fully proves that the inflatable cabinet is not affected by the harsh environment.
· Finally, due to the adoption of maintenance-free product structure, the maintenance work is greatly reduced and the maintenance cost is reduced.
· The shell is designed and manufactured in accordance with the "Pressure Vessel Safety Supervision Regulations" issued by the State Labor Administration of the People's Republic of China in 1981 and the conditions that cannot be reviewed after the equipment is put into operation, so as to ensure the safety and reliability of materials, structures, welding processes and inspections.
· The design temperature of the shell takes into account the upper limit of the ambient temperature indoors plus the temperature rise of the shell caused by the rated current. Outdoors, the influence of sunlight and environmental conditions at the place of use should also be considered.
· The design pressure of the enclosure, which is at least equal to the pressure before gas release in the event of an internal failure.
· The welds of the welded shell, except for the parts that cannot be detected, shall be inspected by non-destructive flaw detection according to the regulations; the welds of key parts and the welds welded by two kinds of materials shall all be inspected; 20% of the total seam length. The welding of the shell adopts laser welding or argon arc welding. For the weld seam of the welded shell, except for the undetectable parts, the non-destructive inspection shall be carried out according to the following regulations.
(1) The welding seams of key parts and the welding seams of tailor welding of two kinds of materials need to be spread out;
(2) The flaw detection length of other welds is not less than 20% of the total length of the butt welds.
The shell is highly sealed. For the dynamic and static seals, the corresponding sealing method is adopted, and the rubber ring is used for sealing.
MV Air insulated Switchgear Panel Applications:
· Air insulated switchgear for utility and industry, covering also highly demanding applications, such as data centers, oil and gas, mining, marine and nuclear power. A wide choice of products designed as per IEC, ANSI, CSA, ENA, GB, GOST and other standards.
· Air insulated switchgear(AIS) adopts the air as the insulation media designed voltage ranging from 11KV to 36KV medium voltage power distribution system. It plays a controlling and protecting role in the power system. The main circuit components of the air insulated switchgear are built in the gas-filled compartment.
· The pressure is constant and not affected by the altitude. It is especially suitable for high altitude areas. The core components of the air insulated switchgear are load switch and fuse, with the advantage of simple structure, small size, low price, and safe power supply.
· It is widely used in power distribution stations and compact substations in load centers such as residential area, high-rise buildings, large public buildings, and factory enterprises. The air insulated switchgear is a secondary power distribution device and is a medium voltage switchgear that redistributes the power of a primary power distribution device that is powered by a high voltage distribution transformer.
· Compared with the traditional SF6 gas insulated switchgear, the biggest advantage of air-insulated switchgear is its more attractive environmental protection performance. It uses dry air instead of traditional SF6, N2 and so on.
· Our Air insulated switchgear are designed for indoor application considering customers’ space constraints. Our switchgear has a metal clad design, and its robust construction ensures it functions well even in adverse environment conditions. We give you a choice of fixed or withdrawable Vacuum Circuit Breakers in the assembly. Switchgear Assemblies, Breakers, Contactors are designed and manufactured according to IEC 62271 series. We assure compact size of assembly without compromising on safety features.
MV Air insulated Switchgear Panel Transport Packaging:
· Our container type compact substation is desined for easy transportation and fast installation. Which is pre-assembled for easy set-up and commissionin.All components type-tested.
· Package substation is prefabricated substation; ready for installation at site. Package substations are most preferred solutions nowadays as there are Concerns regarding space, aesthetics and safety.Much more safety for the public and operators compared to traditional civil works substations.
