<p>A strong magnetic interference prevention device for an electric energy meter and a method thereof. The device comprises a power utilization information collection terminal and a reed relay. A normally-open type reed relay is accessed at one or more switching value input ends of the power utilization information collection terminal. When the reed relay has an external interference magnetic field, the relay is closed, and the power utilization information collection terminal detects a closing signal of the relay, that is, sends an alarm, so as to implement an electricity stealing prevention function for a power user.</p> |
