A fuse interrupts excessive current (blows) so that further damage by overheating or fire is prevented.

保险丝中断过大(打击)电流，防止由过热或火灾造成的进一步损害。

Adding a current limiting resistor or fuse in series with each switch will help prevent this type of damage.

在每个开关上串联一个限流电阻或保险丝，将有助于防止这种类型的损坏。

AC source may not deliver current to blow the fuse in a power supply, it is not suitable for abnormal test.

交流源不会提供足以烧断电源保险丝的电流﹐因此不适合非正常测试。

Its research also suggests many UK adults do not have adequate protection from electrical fires - less than half of those surveyed (49%) have a Residual Current Device in their fuse box, a safety device which minimises the risk of fire by cutting off the power in the event of a fault.

If proven, the technology could rival the current favoured technique for initiating fusion which uses superconducting magnets to contain and fuse the hydrogen nuclei.
