n. （工）V—形（连接），开口三角形（连接）
双语例句
- A simulative test is carried out with a field 10 kV PT, voltages of different amplitudes and frequencies are injected into the open-delta of PT with different concen-trated capacitances instead of grounding capacitance. The calculative results from measured data show its feasibility.
采用10kV现场用TV，用不同集中电容代替线路对地电容，从TV开口三角形侧注入幅值以及频率不等的电压进行模拟实验，从实测数据的计算结果说明，该测量方法是可行的。 - Analysis on Over-high Open-delta Voltage of Secondary Side in 66 kV Potential Transformer
