My Presentation
Switchgear, comprising fuses, disconnect switches and circuit breakers is a vital element in a reliable power system and enables the isolation, disconnection and protection of electrical equipment. It also enables safe maintenance by cutting power to circuits and components in the system, clearance of downstream faults and switching electrical supply from a network power system to a local power generation system.
Such critical equipment has a typical lifespan of at least 30 years and must be robust with low failure rates. As well as conformity with internationally devised and accepted IEC standards, more recent environmental regulations, “green energy”, have increased the demands on the manufacturers and designers of such equipment.
There are many aspects to these standards and regulations which encompass many physical aspects in the design process - mechanical, electrical and thermal. The costs of testing for conformity and product cycle development can be radically reduced by the aid of numerical simulation. Unnecessary tests which may be difficult to perform, be destructive and dangerous may be removed from the design cycle. Switchgear design must adhere to temperature limits, amongst many other requirements, determined by international IEC standards. In order to accelerate the design process, simulation must be able to emulate the physical process according to well-known principles.
To maximize the benefit of simulation, it is critical to include it in the design process. Radical departures from well-known designs may be investigated. The aforementioned challenges in the market may lead to risky and costly changes which can result in fatal operational performance. Simulation can reduce dramatically this risk.
An Electro-thermal simulation enabling these benefits is demonstrated on a typical switchgear component. The CST Studio Suite allows, within a single user-interface, the designer or analyst to perform a combined electromagnetic field (CST EM STUDIO) and Conjugate Heat Transfer (CHT) simulation workflow on a single, fully parameterized CAD model. Data exchange between the simulation types is automatic. A typical switchgear design and possible improvements are subjected to this workflow in order to test for thermal conformity.
