Abstract:
The electrical equipments in automatic weather stations are often stricken and damaged by lightning strokes inducted from AC power lines, and various currently installed lightning arresters cannot effectively prevent the occurrence of the like events. A newly designed and developed lightning protection power switch is introduced, which can isolate electronic equipment from alternating current, uses two groups of storage batteries alternately to supply electric power. The switch detects the battery’s supplying voltage and controls the rotation direction of two micro motors. Through the motors’ transmission devices, the contact point can be shifted. Consequently the two groups of storage batteries can alternately supply power and be recharged. By adjusting the motor’s stroke, the distance between charger and equipment can be 8 cm to 10 cm, and the isolation between power and equipment devices is archived. The lightning inducted accidents and damages through AC power lines can be prevented.
