Description

A High Compatibility Overturning Cart for Circuit Breakers and Porcelain Bottles

technical field

The utility model relates to electric power equipment, in particular to a highly compatible overturning vehicle used for circuit breakers and porcelain bottles. the

Background technique

At present, when installing and overhauling the porcelain vases and circuit breakers of power grid equipment, it is often necessary to turn them over with an overturning vehicle, but the circuit breakers and porcelain vases in high-voltage power grid equipment are very heavy. Taking the 252KV open circuit breaker product as an example, its weight is close to one Tons, the overturning of such equipment not only requires driving (crane) for hoisting, but also requires auxiliary tools to assist in overturning. At present, the commonly used auxiliary tools are overturning vehicles. However, the equipment positioning holes on the current flip car are all fixed, and its height is small and cannot be adjusted, which makes the flip car poorly compatible with different types of circuit breakers, and cannot turn over the circuit breaker with the opening spring, and when the flip car slides , in order to facilitate the control of the trajectory of the overturning vehicle, personnel often need to stand under the hanging object to operate, which has potential safety hazards. For the light-weight circuit breaker and porcelain bottle, although the overturning does not require a turning cart, operators need to manually touch the circuit breaker and porcelain bottle to adjust their inclination angles, which also has potential safety hazards. the
