[0008] According to the remote alarm device for near-power alarm, the second shell is made of stainless steel and is grounded, which is used to protect the electrical components in the second shell and reduce the influence of the electric field generated by the high-voltage electrical equipment on them.

[0009] According to the remote warning device for approaching electric current, the photoelectric switch is a reflective photoelectric sensor, which reduces the influence of the electric field on the photoelectric switch and is used to detect whether an object is approaching.
