After the experience method first puts the wire on the wire, put on the 01 type wire clamp and tighten the wire and the 0 type ring, then put the index finger against the top of the 0 type ring, and cut the line to the next finger. Due to the large current on the low-voltage side of the distribution transformer, the contact surface of the conductor is small (mostly nut contact), and at the same time the ambient temperature is also high, so that the low-voltage side connection bolt of the distribution transformer often has a heating phenomenon. When the heating temperature is too high, it will cause the small oil seal on the upper end of the porcelain casing to deteriorate rapidly or directly burn out and leak oil. In this way, both the operation and maintenance workload is increased, and the load capacity of the distribution transformer is affected. Safety is the benefit. At present, the reform of the rural power system has been further deepened, and the management of rural power should be further deepened. In order to strive for efficiency, agricultural power work must pay close attention to safe production. Facts have proved that only by grasping safety can we achieve benefits, and safety is investment. Safety is happiness. Happiness has various opinions and various understandings, and everyone has their own opinions. Some people say that there is happiness when they have money. I say that peace is happiness. Peace and safety are the foundation of happiness. Without the guarantee of security, there is no happiness. Everyone on our agricultural and electric warfare line must firmly establish the idea of ​​"safety first" and not do anything illegal. For your own sake, for others, please raise your awareness of safety and always keep in mind that safety is the first priority in your work.
In this case, it can be concluded that a short circuit fault has occurred in the line or in the electrical equipment. The fault recovery point should be thoroughly checked before the fuse can be replaced to restore power. A small blown gap is created in the middle of the fuse. This situation is mostly caused by long-term overload of the line or electrical equipment. The cause of the overload should be ascertained, and then the appropriate fuse should be re-compressed before the power can be restored. The fracture is near the crimping fuse and the fracture is small. In this case, the discoloration of the screw is often seen and oxidation has occurred. Therefore, it can be determined that the fuse is blown due to poor contact. At this point, you can replace the new fuse and re-press it to restore power.
