SIMOBREAKER The New Substation with Rotary Disconnector Fully Assembled, Compact and with High Availability
Convincing arguments for the outdoor modular switchgear bay Complete delivery from a single source As well suitable for indoor use Up to 50 % less space required than by a conventional bay Standardized design means quick delivery Foundations based on standard specifications Factory preassembly means quick installation High availability Easily identifiable switching state Control cubicle mounted at operating height (optional) Quick replacement of standard current transformers Economical
SIMOBREAKER The outdoor switchgear with rotary disconnector Smaller transformer stations with single busbar, industrial plants or wind power stations place special demands on outdoor switchgear. The SIMOBREAKER with rotary disconnector was specially designed for these conditions for economical and reliable power supply at a nominal voltage level of 123 to 145 kv. The alternative to traditional outdoor technology The SIMOBREAKER offers an efficient and space-saving alternative for cases where conventional outdoor switchgear with separately mounted high-voltage equipment was previously used. Everything integrated All necessary equipment such as circuit-breaker, disconnector, earthing switch and transformers are combined together in SIMOBREAKER. Complex connections with cables and tubes are just as unnecessary as the provision of separate foundations, steel structures and earthing connections for each individual device. The user is provided with an efficient and standardized overall concept through the intelligent combination and skilful integration of the components of a high-voltage switchgear bay. The user receives a fully preassembled system from a single source: There is no need for the customer to provide any items, the effort involved in matching up and coordination is significantly less and interface problems are completely avoided. New and reliable The design principle of SIMOBREAKER is new, but reliable. That is assured by the use of certified standard components which are successfully in operation in HV switchgear all over the world. 3500 3400 3900 5500
SIMOBREAKER The switchgear for indoors and outdoors For use also indoors We developed SIMOBREAKER to suit this kind of situation: This outdoor technology is also ideal for indoor use. Installation in a building ensures weatherproofing that can be of significant advantage both in countries with problematic climatic conditions and also in industrial plants where substantial contamination is encountered. Furthermore, the complete system occupies only up to 50% of the space required by a traditional switchgear bay. after damage or in a temporary operating situation. The whole switchgear bay can be relocated quickly thanks to its modular design a characteristic that also pays off during power system modifications. The solution for substation expansion SIMOBREAKER can also be used for quick and uncomplicated extension of your existing system. Commissioned quickly Quick commissioning and high availability of the switchgear are needed especially Traditional outdoor switchgear is subjected to severe stresses where extreme climatic conditions or operating environments prevail. Cold, dust or soot can adversely affect operation and lead to shorter maintenance intervals. To avoid this, compact switchgear is needed that also can be used indoors, if necessary.
SIMOBREAKER designed for reliability and quality Modular switchgear bay components: Common baseframe with Circuit-breaker type 3AP1 FG / FI Motor-operated contact gap Current or combined transformer Outdoor control cubicle (optional) EC SIMOBREAKER simply complete The SIMOBREAKER is designed such that the user receives all necessary components from a single source. These components include the motor operating mechanism to give a visible isolating gap, the current/combined transformer for protection and measuring purposes, the outdoor cubicle containing the control and protection systems (optional) and of course the 3AP1 circuit-breaker, alternatively as variant 3AP1-FG (3-pole auto-reclosing) or 3AP1-FI (1/3-pole autoreclosing). All switchgear bays are extensively preassembled and can be put together quickly and easily on site with the aid of the installation instructions, due to the preparations made in the factory. High and consistent quality is assured due to the comprehensive extent of preassembly in qualified production facilities. Uncomplicated, convincing switching principle The SIMOBREAKER switching principle is notable for its uncomplicated mode of operation: The connection between the circuit-breaker and transformer is created by turning the dual rotary disconnector that is located on the rotating post insulator. Standardized local control cubicles The switchgear bay can be equipped with a standardized local control cubicle, if required by the customer. It contains all equipment necessary to operate, monitor and protect a feeder. This cubicle is installed directly on the baseframe. Consequently, with an auxiliary power supply connection, the SIMOBREAKER is fully ready for operation. The control and protection concept is designed to comply with customary specifications. It therefore comprises all functions required for safe and reliable operation. Certified to international and national standards The convincing SIMOBREAKER concept has been proven and certified by means of a range of tests internationally in accordance with IEC and ANSI standards, nationally in accordance with VDE.
