For modern power distribution network, in terms of the stability of power supplement and advancing its reliability, the increasing of power breakers, like disjunctors, disconnectors and triggers, the more reliability of power network we achieved [1-6]. In another words, there is more breaker-sets installed into distribution network, there is less power consumer allocated into each branch. Relatively, when there is power shortage either by network malfunction or planed maintain, there would not be a massive houses be influenced. However, considering from economic aspects, more distribution electrical breakers towards to numerous investment. Unfortunately, this kind of large investment could not lead to a maximum financial benefit. On the other hands, optimizing the setup of distribution switchgears could simply topology of distribution network, which triggers improvement of investment efficiency and reliability of power supplement, also minimize the effects of malfunction. Thus it can be seen that the balance between breakers’ reliability and economy effects is extremely required, which also urges the appearances of different kinds of electrical distribution breakers.
In the long term development, we have got many achievements at distribution switchgear. Such as the vacuum circuit breakers, which have benefits on low maintenance requirement, good operational reliability and environment-friendly characteristic. Also like distribution switchgear with fire-resistant hydrocarbon fluids. The top reason of applying the hydrocarbon fluids into distribution switchgear is one of its chemical characteristics that the fire-point starts at 300℃, which means the reduction of fire and explosion risks. Meanwhile, it is perfect ‘arc-suppressant’, and also is excellent compatible with relative industry materials during manufacturing procedures.
However, current distribution switchgear still cannot satisfy modern distribution network. The development direction of distribution network is no longer to ask no power shortage, however needs to cooperate a bidirectional power flow and power supply from different kinds of power sources, such as solar power, wind power and bio-mass. Current distribution network is required to able to not only have the quick reaction on distribution network error but also higher material requirement to handle even more extreme circumstances and transfer conditions. At these kinds of aspects, distribution switchgear, like vacuum circuit breaker and fire-resistant hydrocarbon fluids switchgear would be hard to meet requirements in power transmission.
The reason of this research aspect is the basement of switchgear firstly. A good topology of distribution switchgear can simplify its following circuit and extra element requiring. Meantime, it can minimize the requirement on materials, which also could help to sharp the investment in materials and manufacture.
On the other hand, a pivotal thing is optimizing the distribution switchgear. Just like mention in literature review, distribution switchgear, such as breaker, load switch, isolation switch, fuses on brunch and etc, needs to be allocated at the optimum positions and with optimum number, which could simplify the topology of distribution network, minimize the influence of distribution power shortage and network failures, sharp the duration and loads of power shortage. In another aspect, it promotes the reliability of power supplement and diminishes the investment on network maintenance and repairing. However, optimizing distribution switchgear is a multiple problem that belongs to un-linear, un-continuous mathematic counting issue.
In this design, it is going to design a distribution switchgear using bridge structure. Specifically, it will start at a theory calculation and mathematic modeling. Secondly, it would be applied into model simulation. Further, if it possible, it is going to complete the hardware manufacture.
