Low voltage distribution equipment maintenance and maintenance

1. Regular maintenance of low-voltage power distribution equipment

Regular maintenance of low-voltage power distribution equipment plays a very important role in ensuring the normal operation of low-voltage equipment. For distribution equipment with poor operating environment, such as general industrial and mining enterprises, enterprises should carry out a comprehensive equipment maintenance about 3 months. The first element of regular equipment maintenance is to make sure that the power distribution system is disconnected from the high voltage system. After the operation is complete, use a special discharge pole to test the discharge and ensure that the equipment has no surplus electricity before the next operation. Maintenance the first step to clean up the equipment inside and outside the health first, and also should pay attention to in the process of the cleaning of equipment cannot use wet cloth to wipe, only can use dry cloth to wipe, in case of wipes can't hit a corner or elsewhere, then blowing device can be used will be the place that is not easy to wipe clean, ensure the whole equipment of cleanliness and hygiene, ensure equipment The heat dissipation is in a good condition. In addition, for the insulation of low voltage power distribution equipment maintenance also need careful handling, first of all need to be alcohol wipes to ensure effective insulation, the second is the connection part of the manual isolation, the maintenance of the place we can use the lubricating oil for lubrication, so add the lubricating oil, on subsequent operating mechanism in operation, will become more flexible and reliable. If the mechanical contact surface of the disconnector is not in good contact, it is necessary to adjust the contact surface. All connection mechanisms, incoming wire connection and outgoing wire connection parts need to tighten screws. Pay attention to tightening strength during operation to avoid sliding wire and other phenomena.

2. Daily maintenance of low-voltage power distribution facilities

The risk factor of routine maintenance of low-voltage power distribution equipment is much higher than that of regular maintenance. Because the whole maintenance process is in the state of live operation, the staff must strictly abide by the operation rules in the maintenance process of low-voltage power distribution equipment, and try their best to minimize the risk. First because of the low voltage power distribution system of routine maintenance is given priority to with clean sanitation, because electrical equipment during operation for the dust is too thick and will cause poor electric heat, caused the accident, so must pay attention to the facilities in the process of cleaning the surface of the dust with dry dishcloth clean anti-static, and in the cleaning process of ground shock sub must keep in mind that it is forbidden to use wet mop Undertake cleanness to its, must use dry mop cleanness, in order to prevent electric leakage passes wet mop conduction to the person body, cause unnecessary accident. There is also a daily maintenance content is to measure the temperature of daily electrical appliances, because to judge whether electrical appliances are running normally, the operating temperature of electrical appliances is a good standard to control, so in daily maintenance, the temperature measurement of daily use of electrical appliances must be standardized and institutionalized. The temperature should be measured at least once per shift in winter and twice per shift in summer. The normal operation of low-voltage power distribution devices can be ensured only by strict management rules and strict rules on routine maintenance.
