ZHENJIANG, China,
Aug. 14,
2024 /PRNewswire/ -- Recently, at the municipal
construction site beneath the 110kV Xiju 923 transmission line
corridor, State Grid Zhenjiang Power Supply Company has
independently developed and deployed an electric proximity alarm
device on the job site, significantly boosting the safety of
electrical construction work, safeguarding both construction
personnel and grid equipment, and establishing a robust safety
net.
This electric proximity alarm device comprises two parts: a
monitoring terminal and a receiving terminal. The monitoring
terminal is installed on the boom of construction machinery, while
the receiving terminal is placed inside the cab, forming an
efficient and sensitive safety monitoring system. Whenever the
construction machinery approaches the preset high-voltage safety
warning zone, the receiving terminal immediately triggers an
audible alarm, promptly reminding the driver to adjust the
operating position and avert the risk of electric shock.
"Construction under high-voltage lines is paramount to
preventing external damage to transmission lines. At this worksite,
the conductor is 19 meters high, and the crane boom reaches 15
meters. The electric proximity alarm device can continuously
monitor the distance between the crane and live conductors, issue
alerts, and be flexibly adjusted according to different operating
environments and voltage levels," explained Zuo Yingnan, the site
supervisor. This alarm device boasts high sensitivity, rapid
response, strong anti-static and anti-interference capabilities,
enabling efficient operation under complex and variable working
conditions. It leverages technological means to minimize the risk
of electric shock accidents and ensure the personal safety of
operators.
To date, State Grid Zhenjiang Power Supply Company has achieved
full coverage of electric proximity alarm devices at hazardous
locations in key construction areas within its jurisdiction. Since
the full deployment of these devices, they have achieved a 100%
accuracy rate in issuing warnings, ensuring 100% personal safety
during construction and 100% safety of grid equipment. This
provides robust support for the safe and stable operation of the
power grid during peak summer demand periods.
