/ Daily News/Guangzhou, July 25, 2022 -- The scorching sun has brought continuous hot weather to Guangdong since July. The extreme heat has brought severe tests to the operation and maintenance of high-speed railway communication equipment. So how is the communication section of Guangzhou Railway Bureau Group Company to build multiple protective barriers for equipment to prevent heat and cool down and safe production?
To ensure that the prevention of equipment "heat stroke" has been effective. Communication network management personnel pay close attention to weather changes, strengthen the high power supply temperature, load monitoring; The temperature and humidity sensor is used to monitor the temperature in the equipment room in real time. The indoor machine room uses air conditioning to cool the equipment. Increase the inspection times of equipment, and deal with problems in time; Ensure the safe operation of communication, to cope with high temperature test.
At the same time, communication workers in the work area, carry out on-site inspection. Focus on high-open power supply, battery, UPS, and other risks and hidden dangers for inspection; And the ventilation, cooling system and equipment with air conditioning operation conditions are closely checked; Check the operation of key equipment; In addition, equipment defects and security risks found in inspection are dealt with in time to form closed-loop management.
The key to prevent "heat stroke" of communication equipment is to build a strong security defense system. Strengthen the construction of talent team, complete the management mechanism, carry out a series of activities such as hidden danger rectification, supervision and inspection, safety construction, and effectively do a good job in the heat prevention and cooling of equipment.
Regularly hold special meetings on "Heat prevention", carry out "expert consultation" for key communication equipment, adhere to the all-day inspection of key equipment operation, timely understand the operation of equipment, implement "all-day pulse", timely understand the real-time dynamic operation of equipment, strengthen all kinds of hidden dangers, improve the security situation and emergency disposal capacity of communication system.
At the same time, the responsibility of equipment charter is fully implemented, and the operation parameters of key equipment and the temperature of each contact on the voltage side are recorded in detail. At the same time, strengthen the inspection of equipment in high temperature thunderstorm weather, test the lightning protection grounding device test point in the inner computer room and issue the test report. Ensure the normal operation and safety of high-speed railway communication equipment during the summer.
< /p>Next, railway communication authorities plan to increase inspection efforts. Focus on strengthening the monitoring means of "black technology", and continue to feel the pulse "ask" the status of communication equipment. Prevent equipment from heatstroke, and make every effort to ensure the safe and stable operation of railway traffic. (Text: Yang Bing, Zhong Li)
