隔离变压器除了保护人身安全以外,还用来对机器维修保养用,起保护、防雷、滤波作用。当然,隔离变压器对人身也不是就**安全,低压系统中,当人的身体接触任意一根线不能形成回路,故而可以减轻对人身的伤害。可对于高压供电系统,虽然隔离变压器中有的中性点不接地,但由于变压器或发电机对地都有泄漏电流,实际上还是相当于经过一个大电阻接了地,只是电流很小,不会对电网造成影响,但当人靠近高压线时就会通过身体与地形成回路,从而造成触电。

Coaxial cable with hard copper wire as the core, outsourcing a layer of insulation materials. The insulating material is surrounded by tightly woven network conductors and covered with a protective material. There are two widely used coaxial cables. One is the 50 ohm cable, which is used for digital transmission. The other is the 75 ohm cable, used for analog transmission, or broadband coaxial cable. This distinction is made for historical reasons, not for technical reasons or manufacturers.
