Problems solved by technology

Although the dismantling and installation of the diversion plate fixed by bolts is relatively convenient, the two diversion plates fixed by bolts will have poor contact due to the accumulated wind swing. Poor contact of the diversion plates will easily cause the clamp to heat up and affect the stable operation of the transmission line.
[0003] In order to solve the problem of poor contact between the two drain plates, there is also a method of welding to ensure that the surfaces of the two drain plates can be in close contact. However, the two drain plates after welding are difficult to disassemble, and it is inconvenient for the staff to disassemble and replace them with new ones. Therefore, there is a need for a convenient disassembly method to separate the two welded drain plates, so as to realize the premise of not affecting the close contact between the two drain plates, and also to ensure that the two drain plates can be separated.

Embodiment 1

[0041] The present application provides an embodiment. This embodiment provides a method for disassembling the drain plate, which includes the following steps: performing low-temperature treatment on the two drain plates 1 welded together by tin solder, and then treating the two drain plates 1 with alcohol. Rinse the connection of the board 1 to dissolve the residual flux, and finally disassemble and separate the two drain boards 1 welded together by tin solder. Soak in cooling liquid stabilized at 13°C, so that the solder layer 3 between the two drain plates 1 gradually turns into a broken powder, and the time required for the entire process of dismantling the drain plate 1 is 24 hours;

[0042] Wherein, the tin solder includes tin powder with a mass percentage of 99.3% and copper powder with a mass percentage of 0.7%.

Embodiment 2

[0044] The present application provides another embodiment. This embodiment provides another method for disassembling the drain plate, which includes the following steps: performing low-temperature treatment on the two drain plates 1 welded together by tin solder, and then treating the two drain plates 1 with alcohol. Rinse the joints of the two drain plates 1 to dissolve the residual flux, and finally disassemble and separate the two drain plates 1 welded together by tin solder. Material wrapping dry ice covers the two drain plates 1, so that the solder layer 3 between the two drain plates 1 gradually changes into a broken powder, and the time required for the entire process of dismantling the drain plate 1 is 1h; The solder includes tin powder with a mass percentage of 98.3% and copper powder with a mass percentage of 1.7%.

Abstract

The present application relates to the technical field of electrical equipment, in particular to a method for disassembling a drain plate, comprising the following steps: performing low-temperature treatment on two drain plates welded together by tin solder, so that the two drain plates welded together by tin solder The drainage plate is separated; wherein, the temperature of the low temperature treatment is below 13°C. This application utilizes that when the temperature of tin is lower than 13°C, white tin will disintegrate into powdery gray tin, so that white tin will undergo a tin infection reaction, and the tin solder layer between the two drain plates welded together by tin solder will gradually change It is made of fragile gray tin, so that the staff can easily separate the two drainage plates. On the premise of not affecting the close contact between the two drainage plates, it ensures that the two drainage plates are easy to disassemble and replace, effectively It solves the technical problem in the prior art that the drain plate fixed by welding is difficult to disassemble.

Description

technical field [0001] The present application relates to the technical field of electrical equipment, in particular to a method for disassembling a drain plate. Background technique [0002] The strain clamp on the transmission line is an important electric fitting, and its drain plate not only needs to bear the pressure of the wire, but also needs to have good electrical performance. At present, the common drainage plate used on the transmission line is to connect and fix two sheet-shaped drainage plates through bolts, which is characterized by simple structure, low processing difficulty and low cost. Although the disassembly and installation of the diversion plate fixed by bolts is relatively convenient, the two diversion plates fixed by bolts will have poor contact due to the accumulated wind swing. Poor contact of the diversion plates will easily cause the clamp to heat up and affect the stable operation of the transmission line. [0003] In order to solve the problem ...
