Y—△减压起动电路的分析改进

Analysing and improving of Y-△ starting circuit

Y—△减压起动因其简单、方便 ,被广泛应用于鼠笼型三相异步电动机的起动 ,但传统的起动电路连接存在一些缺陷 ,电路运行状态不佳 ,易造成电路事故 ,而且起动器体积大、成本高。通过分析探讨 。

Y-△ starters are widely used in cage 3-phase asynchronous motors because of they are easy, but there are some shortages in traditional starting circuit connection, and these shortages can make troubles to the circuit Y-△ starters have large dimension and expensive cost. So we improved the circuit after analysing.
