The world-wide need for power will con-tinue to increase over the coming years due to the constant population growth, ongoing urbanization, and new trends

Gas-insulated medium-voltage switchgear from Siemens

such as electro-mobility, for example. This represents a complex challenge for medium-voltage systems: Due to the increasing number of growing urban areas and increasing real estate prices, switchgear is having to become increas-ingly more compact. In order to achieve climate targets, medium-voltage systems must be able to accommodate increas-ingly more power in the form of renew-able energy. This increasingly requires intelligent switchgear which also has to be both environmentally friendly and sus-tainable from the point of manufacture through operation up to the point of dis-posal. In addition to a high level of per-sonal safety the reliability of the switch-gear is particularly important for a secure supply during operation.

Gas-insulated medium-voltage switch-gear from Siemens is the right solution for all of these requirements.

Reliable wind parks, both offshore and onshoreWind parks also have specific require-ments, not only with respect to the place of use. Our gas-insulated medium-volt-age switchgear, with its climate-indepen-dent maintenance-free technology and minimal space requirements, enable safe connection of the wind turbine and also the entire wind park to the power grid and thus make a sustainable contribution to environmental protection.

Trouble-free in the mining industryIf you need maximum availability and reliability under extreme conditions, such as in lignite open-cast mining, then gas-insulated medium-voltage switchgear from Siemens is the first choice. It func-tions trouble-free around-the-clock also in a dusty atmosphere under the most varied of ambient temperatures and under high mechanical stresses.

High-performance in the metal industryThe performance demands in metal industry companies are enormous: Con-nection loads of up to 300 MW – this cor-responds to a power consumption of more than 300,000 households – are common. Our gas-insulated medium-voltage switchgear can support the safe flow of all processes by reliably switching

and distributing large quantities of power.

The hardest conditions in the oil and gas industryExploration and conveyor systems in the oil and gas industry must have a trouble-free, safe power supply and require maxi-mum power in the tightest of spaces. Gas-insulated medium-voltage switch-gear from Siemens reliably performs its tasks even under extreme conditions. Therefore, they are particularly well-suited for oil and gas applications because the highest operational safety and availability are necessary.

Safety and compactness for modern infrastructureModern infrastructure such as airports and office buildings are placing increas-ingly higher demands on safety, flexibil-ity, and less environmental pollution over the entire service life. Our compact, gas-insulated medium-voltage switchgear in this case helps to support the establish-ment of safe medium-voltage power dis-tribution and reliably provides power to large consumers and the low-voltage sys-tem.

For almost any application

■ Gas-insulated medium- voltage switchgear from Siemens also ensures opti-mum current flow in other applications such as comput-ing centers or branches such as the automotive industry, chemical industry, and the food and beverage industry.

Impressive advantages

Future-proof investmentIn these times of growing cost pressure, it is even more important to decide on the right technology, especially when switchgear represents an investment for decades.

Compactness, performance capability, climate independence, and cost-effici-ency in this case supplement the central aspects of gas-insulated medium-voltage switchgear from Siemens making it a sound investment for the future; it also provides optimum personal and functio-nal safety and reliable, maintenance-free operation.

In addition, our service contributes to power distribution: Within the scope of Totally Integrated Power, we offer you much more than products, systems, and solutions for power distribution. We will support you through the entire process and life-cycle of switchgear – starting from the initial idea to completion and after-sales service. We offer tools for planning of system architecture and its switchgear, support the specifications of energy management and monitoring, and we offer training and education in the perfect use of our product line.

7

CompactA gas-insulated medium-voltage switch-gear also assures you many advantages in the future due to the technically supe-rior solutions including protection of your investments from the target-oriented switchgear extension. Thanks to its com-pact construction, it offers you space sav-ings and provides the space for new func-tions or the compact design of transformer substations. Space savings are up to 70 %, e.g. for a 36 kV switchgear for primary distribution.

Maintenance-freeA cost-efficient operation is one of the key factors for system operators. This also includes particularly long mainte-nance intervals.

Hermetically-sealed, welded switchgear vessels made of stainless steel (sealed pressure system) ensure tightness for the entire service life as per IEC 62271-200, which means that maintenance of func-tion is normally determined by the ser-vice life of the switchgear. This is deter-mined, for example, for vacuum circuit-breakers under normal ambient conditions as per IEC 62271-1 with up to 10,000 operating cycles without relubri-cation or readjustment.

Our switchgear is therefore practically maintenance-free – which ensures maxi-mum availability with extensive cost-effi-ciency. Advantages, that mean real money for every switchgear operator.

Climate-independentEven under extreme ambient conditions, such as salty air, high air humidity, con-ductive dust or condensation, our gas-insulated switchgear has proven to be the ideal solution and, depending on the switchgear design, will fulfill your needs regardless of the altitude. They are reli-able, owing to the superior technology – which ensures the safety of your distribu-tion system.

IntelligentIn the age of intelligent grids, so-called Smart Grids, stations must be able to integrate smoothly into the new grid con-trol structures. With respect to integra-tion into such upstream control and energy management systems: There are a variety of communication and telecon-trol units available for implementing an interface via various protocols (e.g. IEC 61850, IEC 60870-5-101/104, PROFIBUS, MODBUS, DNP).

To do this, medium-voltage switchgear should also be equipped with the neces-sary actuator (e.g. motor drives) and sen-sors. Depending on the configuration, errors can be localized more quickly, and measured values can be gathered and transferred. In addition, load curves can be recorded, overloads can be detected early on, decentralized supply can be controlled, and losses in the distribution system can be minimized.

8

Personal safetyGas-insulated medium-voltage switch-gear from Siemens is very safe. They meet international standards and specifi-cations for switchgear and are internal arc classified in accordance with IEC 62271-200. Thereby, a high level of personal safety is achieved, among other things, by design measures such as the hermetically sealed, shock-proof primary enclosure and the metal enclosure of all high-voltage conducting parts, including cable terminations, busbars, and voltage transformers, as well as earthed sheath-ing.

In addition to standard protection class IP 65 for all high-voltage parts, the pri-mary circuit ensures advanced control logic to provide additional safety. Logical mechanical interlocks prevent malopera-tion. In addition, safe isolation from sup-ply can be verified with a capacitive volt-age detecting system. All operating mechanisms and auxiliary switches are accessible outside the primary enclosure without danger, while operation is possi-ble, depending on the system, only with the switchgear enclosure closed.

Security of operationCost-efficient goals go hand-in-hand with a high level of operational safety. Gas-insulated switchgear from Siemens will support you with a largely maintenance-free, stable, and tested design – for maxi-mum availability even under extreme environmental conditions. Thus, the her-metically sealed primary enclosure makes the switchgear insensitive to environ-mental influences but also to the pene-tration of foreign objects or small ani-mals.

No significant electrical fields occur out-side the enclosure, which means that no partial discharge can occur in the long term. The electrical and thermal stresses of the current transformers as well as the low-voltage components are practically zero.

Environmentally responsibleOur manufacturing plants are certified in accordance with DIN EN ISO 14001 – we place particular value on the preservation of resources in all of our processes. This also means that we select environmen-tally compatible materials, even at the product development phase, and mini-mize the material and energy consump-tion through production-friendly develop-ment. Thus, our gas-insulated switchgear has a small “footprint” not only because of the compact design but also from an ecological perspective.

9

After its service life, lasting decades, is over, we take on the responsibility of recycling the switchgear in accordance with the valid standards.

ReliableGas-insulated medium-voltage switch-gear from Siemens are of high quality and perfectly tailored to the specific cus-tomer requirements and the respective place of use of the switchgear.

We achieve optimum adaptation to local challenges through our internationally constituted development teams and cus-tomer-oriented manufacturing centers, which are certified according to DIN EN ISO 9001 and 14001. Crucial for high- quality, however, are the excellent train-ing and education of our employees and the use of innovative technologies such as highly precise laser welding systems that we use to ensure that the switchgear vessels are gas-tight.

We check every switchgear vessel with helium in the vacuum test cell for leaks. Our goal for each individual switchgear vessel is “Sealed for life”.

We also do not compromise with crucial components such as insulation parts made of cast resin; instead, we produce them ourselves and ensure their quality and function 100 % by X-ray and tight-ness, high-voltage, and partial discharge testing.
