High-Voltage Circuit Breakers | iPDF Live tank circuit breakers Chapter overview Dead tank circuit breakers Compact switchgear Disconnecting Circuit Breaker Circuit breakers from Siemens Energy The availability of electric energy is vital for economic development and for quality of life and the demand is constantly increasing. One of the necessary conditions for a reliable electric power supply is a well-functioning transmission system. Siemens Energy worldwide supports customers along the entire chain of energy conversion, with an efficient range of products, solutions and know-how for the transmission...

High-Voltage Circuit Breakers | iPDF Chapter overview Type designation Basic components are identical and based on decades of manufacturing and operating experience. Our GIS switchgear range also includes the same interrupter units, operating mechanisms and control elements. By applying this proven modular design not only at our lead factory in Germany, but also within our global manufacturing network, we are able to fulfill the highest expectations regarding availability and reliability at eminently competitive prices. This modular principle can also be found in the type definition of our high-voltage...

Chapter overview High-Voltage Circuit Breakers | iPDF The control system includes the secondary technical components required for operating the circuit breaker, which are mainly arranged in the control cabinet. The control, tripping, motor and heating power supplies can be selected by the customer. Two standard control variants are available depending on your requirements. The basic variant includes all control and monitoring elements that are needed for operation of the circuit breaker, including the following: • Switching operation counter • 19 auxiliary switch contacts (9 normally open, 9...

High-Voltage Circuit Breakers | iPDF Chapter overview Controlled switching Controlled contacts with PSD with SICEA01 Circuit breaker monitoring Sensgear™ - Born connected While monitoring eguipment can already provide a lot of information, the focus of Sensgear™ is goes beyond common asset management, it supports active management of the grid. With Sensgear™ the gas-insulated switchgear or circuit breakers transmit their current status in near-real time via an online application. This facilitates gualified decision-making and optimized grid management, which which results in more flexibility...

High-Voltage Circuit Breakers | iPDF Chapter overview Vacuum interruption principle Self-compression Dynamic selfprinciple compression principle Interruption principlesVacuum interruption principle Vacuum interrupters form the backbone of our 3AV1 blue portfolio. Based on more than 40 years of experience in medium-voltage range and more than 6 million delivered vacuum interrupters, Siemens Energy has introduced this proven technology to high-voltage power networks in 2010. The technology is characterized by a number of distinctive features, such as • High reliability due to the hermetically tight...

Chapter overview High-Voltage Circuit Breakers | iPDF Stored-energy spring mechanism The operating mechanism is a central part of high-voltage circuit breakers. The drive concept of the 3AP circuit breaker family is based on the patented stored-energy spring principle and is identical on all types. The use of such an operating mechanism for voltage ranges of up to 1100 kV became appropriate as a result of the development of a self-compression interrupter unit that reguires minimal actuating energy. The compact design of this operating mechanism makes it possible to place the stored-energy spring...

High-Voltage Circuit Breakers | iPDF Chapter overview Quality right from the start Development and type testing The foundation of guality for Siemens Energy circuit breakers begins right in the development of a new product. Switching performance, high voltage stability and performance under normal mechanical loads (wind and short circuits) as well as seismic conditions are simulated and optimized in the outline design phase using digital twins. The use of parts and assembly units in a large number of breaker types such as live tank, dead tank, as well as GIS leads to a high volume standardization...

High-Voltage Circuit Breakers | iPDF Chapter overview Easy installation and commissioning Our circuit breakers for voltage ratings from 72.5 kV to 300 kV can be transported fully pre-assembled and routine-tested. All higher ratings are dismantled into compact, clear and space saving subassemblies for transportation purposes. Transportation costs are minimized by packing several circuit breakers together in one shipment. The subassemblies can quickly be installed into a complete circuit breaker at the substation. A single supervisor can install one circuit breaker within one and a half days. Due...

High-Voltage Circuit Breakers | iPDF Chapter overview Technical data 3AV1FG Blue live tank circuit breaker Vacuum technology is the game changer for F-gas-free highvoltage power grids The outstanding technical performance and low lifecycle costs of vacuum circuit breakers make this solution the preferred technology and led to a phase out of SF6 in power networks up to 52 kV. The same proven technology paved the way for climate-neutral high-voltage applications of Siemens Energy since 2010. The member of our Blue product family is designed according to our well proven modular platform concept...

High-Voltage Circuit Breakers | iPDF Chapter overview Technical data 3AP live tank circuit breaker For applications from 72.5 kV up to 1100 kV In contrast to dead tank circuit breakers, the interrupter unit in live tank breakers is not grounded during operation; it is exposed to high-voltage potential and therefore these circuit breakers are called live tanks. The 3AP circuit breaker family is available for rated voltages from 72.5 kV up to 1100 kV. 3AP1 circuit breakers up to 300 kV are equipped with one interrupter unit per pole and 3AP2 circuit breakers up to 550 kV include two interrupter...
