Description

Technical Field

[0001] The utility model relates to the technical field of vacuum circuit breakers, in particular to a wiring device for a vacuum circuit breaker. Background Art

[0002] The high-voltage vacuum circuit breaker is named because its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no need for maintenance after arc extinguishing, and is widely used in distribution networks.

[0003] The existing announcement number is CN219832505U, and the name is a high-voltage vacuum circuit breaker wiring structure. Through the wiring device set up, the wiring device can connect one end of the current transformer with the external wiring terminal internally, which has a protective effect compared with the existing structure. The two sets of screw structures can move the limit blocks therein under the control of the knob to expand or reduce the distance between the two to clamp the external cable, and finally fix it through the fastening nut and contact block therein to prevent it from falling off. When the device is in use, it relies on the internal structure to tightly fix the current transformer and the external cable, and its external structure plays a protective role. The adjustable spacing limit block can adapt to cable structures of various sizes to achieve the purpose of easy use.

[0004] However, the above-mentioned high-voltage vacuum circuit breaker rotates the screw to push the limit block to clamp and squeeze the cable to maintain stability. However, the cable is affected by external wind force, which easily causes pulling on the clamped cable. This results in the lack of a slow-release structure for the pulling force on the clamped cable, causing cable damage. Utility Model Content
