TECHNICAL FIELD
[0001] The utility model belongs to the transportation technical field of power supply and distribution equipment, and particularly relates to a bushing fixing tool for tank circuit breaker whole machine transportation. BACKGROUND
[0002] In the export project of tank circuit breaker products, the traditional transportation method often involves removing the bushing for separate transportation, which not only increases the demand for bushing transportation packaging boxes, but also leads to additional workload of bushing butt joint after the products arrive at the site, and increases the consumption of insulating gas. This problem is particularly prominent in the export of 26kV tank circuit breaker products. The process of removing and reinstalling the bushing is not only cumbersome, but also easy to cause bushing damage during transportation and butt joint, increasing project cost and time cost.
[0003] In the delivery process of 126kV tank circuit breaker products, the traditional method is to place the three-phase bushing in a wooden packaging box, while the circuit breaker body and current transformer are installed together. Although this method ensures the safety of the product to a certain extent, it still has many problems. For example, the bushing and the circuit breaker body need to be butt jointed on site, which not only increases the workload, but also may cause problems such as oxidation of silver-plated parts and penetration of external moisture.
[0004] With the increasing of export projects, the demand for whole transportation of tank circuit breaker with bushing becomes increasingly urgent. In order to meet this demand, save cost and eliminate the risk of bumping and collision when the overseas project user butt joints the bushing without guidance, it is particularly important to develop a new type of whole machine transportation bushing fixing connection tool.
