Description

technical field [0001] The invention relates to a platform-changing combined protection appliance, which belongs to the technical field of electric power transmission. Background technique [0002] High-voltage combined electrical appliances are divided into two types: open type and fully enclosed type according to the insulation structure. The former is based on an isolating switch or a circuit breaker, and is composed of components such as a current transformer, a voltage transformer, and a cable head. The latter is to seal the high-voltage live parts of each component in a grounded metal shell, and the shell is filled with gas, oil or solid insulating medium with good insulation properties. Transformers, current transformers, busbars, lightning arresters, cable terminals, etc.) are connected in sequence and form a whole according to the wiring requirements. Sulfur hexafluoride (SF6) fully enclosed electrical appliances that appeared in the 1960s have the characteristics...
