In order to ensure the normal power supply of the electric field, we need to regularly check and maintain the high and low voltage complete equipment in our daily work, and make records so that we can analyze the operation and power consumption at any time, find problems and eliminate hidden dangers in time.
1. Whether the names, marks, numbers, etc. of electrical components on the high and low voltage complete equipment are clear and correct, whether the positions of all operating handles, buttons, keys, etc. on the panel are consistent with the actual situation on site, whether they are firmly fixed, and whether the operation is flexible.
2. The power distribution panel indicates whether the signal lights such as "closing" and "opening" and other signal indications are correct.
3. Check whether the contacts of disconnectors, circuit breakers, fuses and transformers are firm, and whether there is overheating and discoloration.
4. Whether the insulation of the secondary circuit conductor is damaged or aged.
5. When the distribution panel is marked with an operating analog board, whether the analog board corresponds to the operating state of the on-site electrical equipment.
6. Whether the instrument or dial glass is loose and whether the instrument indication is correct.
7. Whether the lighting fixtures in the power distribution room are intact, whether the illumination is bright and uniform, and whether there is glare when observing the instrument.
8. Problems found in patrol inspection shall be handled in time and recorded.
Special personnel shall be assigned to supervise the work of high and low voltage complete equipment, use tools with insulating handles, stand on dry insulating materials, wear insulating gloves and helmets, wear long sleeved clothes, and prohibit the use of files, metal rulers, brushes and dusters with metal objects.
