Abstract

An intelligent breaking electric drop-out fuse system provided by the present invention comprises a fuse body, the fuse body comprises an opening hook, an insulating pillar, a fusion tube and an opening hook base, and the opening hook base comprises a U-shaped seat connected with the insulating pillar; the two inner sides of the U-shaped rocker arm are rotationally connected to the two outer sides of the U-shaped seat through a first connecting rotating shaft, and the U-shaped rocker arm is connected with the opening hook; the limiting mechanism is arranged on the U-shaped rocker arm; and the buffer mechanism is arranged on the U-shaped seat. A limiting mechanism is arranged and is used for limiting rotation of the U-shaped seat, so that the U-shaped seat is prevented from swaying by 360 degrees, and the use of the fuse is prevented from being influenced; the limiting mechanism has the advantage of simple structure; and the buffering mechanism is arranged and used for preventing oscillation when the U-shaped base swings back, and the buffering effect is achieved.

Description

technical field [0001] The invention relates to the technical field of fuses, in particular to an intelligent breaking electric drop-out fuse system. Background technique [0002] A drop-out fuse is generally installed on the transformer incoming grid to protect the safe operation of the transformer. The traditional drop-out fuse is operated manually, and the operator uses the operating rod to open or close the switch. If it is operated in rainy days or at night, there are even more potential safety hazards. For this reason, the electric control drop-out fuse has been developed rapidly. However, the existing electric control drop-out fuse has defects, such as the lack of a rotation limit mechanism at the base of the opening hook. When the swing angle of the opening hook is too large, it is easy to affect the fuse. device use. Contents of the invention [0003] The invention provides an intelligent breaking electric drop-out fuse system, which is used to solve the technic...
