Description
Technical Field
The invention relates to the field of explosion wire pressing protection devices, in particular to an explosion compression joint energy control box with low noise and high safety and a using method thereof.
Background
Explosive crimping is a common means of wiring in overhead power lines. Generally, the construction process of explosive compression bonding of power lines and the operation sequence thereof are as follows: (1) inspecting and cutting the pipeline: 1) before cutting the pipeline, the power line should be checked for defects; whether the crimping pipe is cracked and has defects such as sand holes and the like, and whether the pipe diameter of the crimping pipe meets the standard; 2) when cutting a line, two sides of a cut of the line are firmly tied by a string, the cut needs to be perpendicular to a linear axis and flat, and burrs on a cutting surface need to be filed. (2) Cleaning the pipeline, and drying in the air or baking by using a blast lamp. The clean length of the pipeline is not less than 1.5 times the explosive crimp length. (3) And applying a protective layer. Before the surface of the compression joint pipe is wrapped with the medicine bag, 1-2 protective layers are wrapped, and the thickness of the protective layers is preferably 1.5-2.0 mm. (4) Medicine cutting and medicine packing: 1) according to 1: 1, taking over the size of the outer circumference of the tube to cut the medicine, and trying to accurately cut the medicine; 2) when the medicine bag is wrapped, the tablets are required to be tightly attached to the compression joint pipe, no gap is left at the joint of the tablets, and the tablets cannot be stacked and wrapped. (5) And (6) threading. Threading is carried out according to the connection mode and the requirement of the thread end, and whether the specification and the model of the pipe and the thread are consistent or not needs to be carefully checked during threading. (6) And (4) blasting. When the detonation work is finished, and the detonation is accurate after the detonation is checked to be correct. (7) And (6) finishing. After the explosive crimping is completed, the quality of the crimp should be checked and the residual dirt on the crimp tube should be wiped clean. Finally, red lead is coated on the two ends of the saw kerf of the pipe and the length of the power line which is possibly affected by the explosion action to prevent corrosion.
