INTRODUCTION
MEWOI1870 Series Arm Type High Voltage Approach Electric Alarm provide a safe, practical and convenient new type high voltage alarm device for close-electric operator. During live electric working, the safe distance between operator and live body should not be closer than the requirement of relevant working regulations. After the operator wearing this alarm, when close to the high voltage charged body for a certain distance, according to the corresponding safe distance of voltage level, the alarm will make out the sound and light alarm to remind the electrical workers to pay attention to safety and avoid high voltage electric shock accidents. MEWOI1870 Series Wist Type High Voltage Approach Electric Alarm develop with two model of high voltage alarm(above 1KV) and low voltage alarm(below 1KV), adopt non-contact induction technology, accurate alarm, power saving and durable, standby time up to 12 months. The alarm with unique automatic trigger detection function to ensure the safety of close-electric workers. The alarms are widely used in electric power, railway, industrial and mining enterprises and other close-electric working places. |
