Abstract
The utility model discloses a metering handcart suitable for a switch cabinet. The metering handcart is mainly composed of a chassis vehicle, voltage transformers, a vehicle frame, a secondary plug socket, an insulator, a contact arm bushing, a contact arm, a plum blossom contact, composite sheath metal oxide lightning arresters, a silicone rubber high-voltage line, and high-voltage fuses. Three voltage transformers are installed on a same bottom plate side by side and are connected in a star connection manner. The high-voltage fuses are disposed in the voltage transformers and are fixedly sealed with the voltage transformers. The metering handcart reasonably distributes limited space so as to provide the handcart with reasonable and compact structure and to guarantee good mechanical performance and electrical performance of the handcart.
