{4 q$ ?9 Z/ H- @/ ]) i標准提到試驗手指不能觸及帶電部件,但電機的銅線是不是帶電部件?它本身表皮都有一種絕緣漆保護的吧。 29.1.1 The clearances of basic insulation shall be sufficient to withstand the overvoltages likely to occur during use, taking into account the rated impulse voltage. #The values of Table 16, or the impulse voltage test of Clause 14, are applicable.$ NOTE The overvoltages may be derived from external sources or due to switching. The clearance at the terminals of tubular sheathed heating elements may be reduced to 1,0 mm if the microenvironment is pollution degree 1. !Lacquered conductors of windings are considered to be bare conductors." Compliance is checked by measurement.
