Dc switching power supply is the heart of communication system, and its operation quality is directly related to the working quality of communication network on-line equipment. To ensure the smooth, reliable, safe and high-quality operation of the power supply, to ensure that the index values of various power supply systems conform to the requirements of the power supply system of the communication equipment, to ensure the smooth operation and smooth communication of the communication equipment. Power maintenance staff is the key technical energy to ensure the smooth operation of power supply. In-depth discussion on the statistical analysis method and maintenance measures of dc switching power supply system anomaly is beneficial to the proper operation and troubleshooting of power maintenance technicians in the maintenance and inspection process to ensure the normal operation of power supply equipment in a timely manner. So, what points need to pay attention to the maintenance of DC switching power supply? Below, follow the small make up to understand.

1. Pay attention to site safety inspection

Regularly inspect and test the communication power equipment, pay special attention to the working temperature and equipment management of the main machine room, use the power video monitoring system, real-time monitoring system power equipment of various main operating parameters, find problems properly handled.

Patrol inspection must check the power supply working state, the control module is equipped with effective, battery charging current limit value is appropriate, is there any alarm, alternating current, the electric system software flow, dc floating work voltage, load current and battery charging power flow, fan management status, lightning protection devices, power transformer main parameters monitor all kinds of operation control module is appropriate, normal temperature compensation is enabled. Switching power supply module is not less than 5% current etc. Battery commercial insurance, battery connection strip leakage current, whether the battery has acid, liquid leakage, drum and other problems. The working temperature of the main machine room is in accordance with the maintenance regulations, etc.

2. Use remote monitoring

The remote monitoring system can be used to establish a remote monitoring system for power supply equipment. The fault can be known according to the remote monitoring system, and can be handled according to the remote monitoring system according to the fault that can be solved by the remote control. The fault that cannot be solved must be solved immediately at the site. At the same time, the power video monitoring system is used to detect whether the various data signals of the power supply are normal and whether there are errors in the statistical data.

3. Handle faults properly

When solving the power equipment fault, the cause and location of the power fault should be judged first, and then effective ways and measures should be taken to solve the power fault. For more serious breakdown must consult the responsible person leading cadre.

4. Looking for technical support

For power failure that cannot be solved immediately, it is necessary to consult technicians of relevant manufacturers by telephone. If specific instructions by telephone are still difficult to solve the problem, it is necessary to use the current accessories to temporarily repair the power supply system of power equipment. Meanwhile, fault records should be made and technical personnel of relevant manufacturers should be notified to bring accessories for repair.
