State Grid Zhenjiang Power Supply Company Develops Self-Made Electric Proximity Alarm Device to Enhance Construction Safety
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.
最近，在110千伏西局923输电线廊下的市政建设工地上，国家电网镇江供电公司独立研发并部署了一种电气近距离报警设备，显著提高了电力施工工作的安全性，保障了施工人员和电网设备的安全，建立了一个强有力的安全防护网。
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.
这种电气近距离报警设备由两部分组成：监测终端和接收终端。监测终端安装在施工机械的臂上，而接收终端则放置在驾驶室内，形成了一个高效而敏感的安全监测系统。每当施工机械接近预设的高压安全警戒区域时，接收终端立即触发声音警报，及时提醒驾驶员调整操作位置，避免触电风险。
"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.
“在高压线下进行施工是防止输电线路外部损坏的关键。在这个工地上，导线高达19米，起重机臂达到15米。这种电气近距离报警装置可以连续监测起重机和带电导线之间的距离，发出警报，并根据不同的操作环境和电压级别进行灵活调整，”现场监理左应男解释道。该警报装置具有高灵敏度、快速响应、强抗静电和抗干扰能力，在复杂多变的工作环境下实现高效操作。它利用技术手段来最小化触电事故的风险，确保操作人员的人身安全。
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.
截至目前，国家电网镇江供电公司已在其管辖范围内的重要施工区域的危险场所实现了电气近距离报警装置的全覆盖。自装置全面部署以来，它们在发出警告方面实现了100%的正确率，保证了建设期间100%的人身安全和电网设备的安全。这为夏季高峰期电网的安全稳定运行提供了有力保障。
