Technical Field

[0001] The utility model relates to an electric circuit breaker transfer vehicle, belonging to the field of high-voltage cabinets. Background Art

[0002] Vacuum circuit breakers are extremely promising power interrupting devices in the low-voltage and medium-voltage fields. They are switchgear that use vacuum as insulation and arc-extinguishing medium. Gas molecules in a vacuum are extremely rare, and there is little chance for electrons to collide with molecules, so the insulation strength of vacuum circuit breakers is very high. Since circuit breakers weigh hundreds of kilograms or even more, a special transfer vehicle is required to move the circuit breaker into or out of the circuit breaker room to facilitate the installation, safe maintenance, and overhaul of the circuit breaker. Therefore, a service trolley is an essential accessory to ensure the operation of the circuit breaker.
