[0002] Trolleys include circuit breaker trolleys, PT trolleys, isolator trolleys, fuse trolleys, and metering trolleys. As key components in withdrawable switchgear, trolleys generally come in two types: PT trolleys and switch (circuit breaker) trolleys. For example, when the switch is disconnected, the switch trolley can be manually withdrawn from the switchgear after laying out guide rails for maintenance or replacement. The trolley primarily houses primary electrical equipment such as circuit breakers and instrument transformers. Within the switchgear, these trolleys have three states: operating, test, and disconnected. When inspecting a high-voltage safety cabinet, all 10kV compartment trolleys must be removed from the cabinet to prevent potential safety hazards.
