Abstract

The invention relates to a power distribution rack falling type fuser lower connector wiring terminal bar. The power distribution rack falling type fuser lower connector wiring terminal bar is characterized in that a body comprises a connection section, a horizontal section and a tail section, wherein the connection section and the horizontal section, and the tail section and the horizontal section are arranged obliquely; the connection section and the tail section are provided with bolt holes and the bolt holes are connected with bolts; the horizontal section is provided with a connection hole; and the connection hole is connected with a bolt type grounding ring. The power distribution rack falling type fuser lower connector wiring terminal bar is simple to mount, simple and convenient to operate, and safe and practical; and the safety, economical efficiency and reliability of a power grid can be improved.

Description

technical field [0001] The invention relates to a drop-out fuse, in particular to a lower contact terminal block of a drop-out fuse on a distribution platform. Background technique [0002] Due to the characteristics of economy, flexibility and strong adaptability to the environment, drop-out fuses are widely used in the primary side of transformer racks on poles and cable racks as overcurrent protection switchgear. However, in the application process of drop-out fuses, there are also some disadvantages due to the structure of the lower contacts. The details are as follows: [0003] 1. The copper-aluminum contact of the drop-type lower contact is easily broken at the copper-aluminum junction due to wind swing and other reasons, thus causing failure. [0004] 2. The actual contact area between the drop-down lower terminal contact and the copper-aluminum node of the transformer horizontal bus lead is insufficient, which may easily cause the contact to overheat and burn. [0...
