Maintenance scheme of image monitoring system in t

The maintenance scheme of substation image monitoring system

1.2m cable, wire, power supply, video cable, control cable laying

cable trench and cable duct should be surveyed by predecessors to ensure the smooth laying of cables. Before laying, the members of the alliance should check whether the cable is mechanically damaged according to the division of labor. Although the cable deformation continues to occur, whether the insulation between the core wire and the fence layer is qualified, and whether the cable reel is intact. The zigzag radius of the cable shall meet the requirements of the construction standard. The cable shall use the whole cable. Cables shall be neatly and firmly laid in the cable trench. For the fire prevention of cables, fire-proof bags and fire-proof blocking materials shall be adopted in the cable trench, and fire-proof partitions and blocking materials shall be adopted at the place entering the cabinet

2. Cable discussion production and check

the production of cable discussion should be the same construction process, so as to be neat and elegant. Cables are arranged neatly and in clear layers in the cabinet; The cable plate shall be clearly marked with cable specification, starting point, starting point and cable label. Before the power cable is powered on, use a multimeter to measure the voltage of each core to the ground. After the 2m cable is laid with nearly one million recycled plastic bottles, the 2m codeless tester should be used to test the channel loopback to confirm that it is correct. After laying, the line should be tested with a collection tester to discuss whether the contact is outstanding

a hard disk recorder is installed on the video monitoring screen, and a peace converter is installed on the distribution frame. Wiring shall be carried out in strict accordance with the diagram, and the label of each electrical component on the panel, cabinet and box shall be clear. The cable core number plate shall be taken from Jinan new era Gold Testing Instrument Co., Ltd. according to the relevant reference standard: GB ⑴ 2137 T, the plastic label shall be taken

4. Enron technical measures

1. After the exchange power cable is connected to the power terminals on both sides of the image monitoring screen and the communication DC screen, use a multimeter to test whether the front of the cable cores connected to both sides, the zero line and the ground line correspond and whether there is a short circuit between the cable cores on both sides. Before the exchange power cable is connected to the power terminals on both sides of the image monitoring screen and the communication DC screen, the exchange air switch must be disconnected and closed with insulating tape. It is strictly forbidden to close the air switch

2. Before the source line of the hard disk video recording motor is connected, use a multimeter to measure the voltage to the ground of the front, zero line and ground line of the exchange, confirm that there is no electricity, and disconnect the source air switch of the hard disk video recording motor

3. When the secondary wiring of the exchange cable from the image monitoring screen to the communication DC screen is connected, it can form an exchange short circuit or grounding, and care and isolation measures should be taken

4. When going out of the garden for construction, you must wear a safety helmet accurately before going out, and when climbing up and landing, you must wear a safety belt accurately

5. Keep sufficient safe separation from live equipment, with 35kV greater than 1m and 10kV greater than 0.7m

6. During the inspection, it is necessary to carefully check whether the manufacturer's drawings are suitable for the objects. If any defect is found, it should be reported to the leader in time and corrected. Then it should be taken care of and noted on the drawings

7. The person in charge of the task must stop the safety disclosure and risk point analysis to the members of the task team before the task, so as to ensure that each task staff is familiar with the on-site situation

8. Before the end of the task, the person in charge of the task should work with the person in charge of the team to compare and record the safety measures done, stop carefully checking them, and ensure that all safety measures return to normal

5. Civilized construction

1. The task garden should be kept clean, and things and experimental assemblies should be placed neatly

2. The drawings checked on site should be placed neatly, and the unneeded drawings should be placed in the document box. It is strictly forbidden to litter

3. At the end of each day's task, the person in charge of the team should be responsible for cleaning the site and putting away the experimental assembly, drawings and things neatly

4. After the end of the task, the site should be cleaned and restored
