定义
A specialized insulating frame or support component designed for transition resistors/reactors in electrical systems. It provides mechanical support to maintain proper positioning of electrical elements while ensuring high-voltage electrical isolation between conductive parts and grounded structures. This component prevents electrical arcing, reduces leakage currents, and maintains safe operational distances in high-voltage environments.
工作原理
The insulating frame/support operates on the principle of dielectric isolation, using materials with high dielectric strength to prevent electrical current flow between conductive components. It maintains physical separation between energized parts and grounded structures while providing structural rigidity to withstand mechanical stresses from thermal expansion, vibration, and electromagnetic forces during operation.
