Bolt and nut connection is one of the most basic assembly in the electromechanical industry. When the coupling is too tight, the bolt is prone to metal fatigue under the long-term action of mechanical force and electromagnetic force, and the coupling or shearing of the thread is too loose. To loosen the assembly between the parts and cause an accident. For the bolting and nut connection of electrical engineering conduction current, not only the mechanical effect should be paid attention to, but also the electrothermal effect should be paid attention to. The crimping is not tight, the contact resistance is increased, and the heat is generated during the energization - the vicious cycle of contact surface oxidation-resistance increase Until severe overheating, burning joints, causing a short circuit to ground, disconnection accidents. For primary equipment and busbars, the parallel groove clamps, T-clamps, equipment clamps, and wiring of the connecting wires may cause accidents of different degrees.
