Coil for us is not strange, with the continuous development of economy, science and technology, the coil in our lives everywhere, a wide range of applications. Has now been applied in various industries. We are pleased with the achievements of the coil, we should also pay attention to the use of the coil when the problems arise. We often encountered in the use of the coil coil burned. For we know that is why coil burn out the following reasons:
1, the load is too heavy, the current flow through the coil increases, the coil surface heating. The insulating paint burned coil wire caused by interturn short circuit load to short circuit load and load power is too large.
2, the coil sheath insulation performance is poor, in a long time or high temperature and high humidity conditions insulating paint due to the aging of the insulation to the role, winding inter turn short circuit, and then passing through the coil current is increased, and the burned - out coil.
3, the coil sheath is artificial or machine for damage caused by turn to turn short circuit.
Burn after ring coil coil will cause a short circuit and interturn short circuit after their resistance and inductance will change.
When we know the reason why we should burn the coil try to avoid this happening again.
