Abstract

The invention relates to the technical field of power supply, in particular to a fuse device and a load switch fuse assembly cabinet including the device. The fuse device comprises an upper end cover,a bushing, a fuse and a mounting cylinder. An upper end cover is provided with a push rod, a crank arm and a push rod; A push rod is arranged on the upper part of the upper end cover and extends to the outside of the upper end cover; The ejector rod is vertically arranged inside the upper end cover and the bushing; The crank arm is arranged between the push rod and the ejector rod and is articulated with the upper end cover at the articulation point, the ejector rod can push the crank arm to rotate around the articulation point, and the crank arm can push the ejector rod to move; A bushing ispositioned below that upper end cover; A fuse is positioned below the bushing, and an impactor is arranged at the top of the fuse; The mounting cylinder sleeve is arranged on the outside of the bushing and the fuse. By providing a fuse device and a load switch fuse assembly cabinet including the device, the invention can effectively improve the triggering reliability of the system.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a fuse device and a load switch fuse combination cabinet including the fuse device. Background technique [0002] In the field of high-voltage switchgear, load switch fuse combination cabinets are widely used. [0003] The load switch fuse combination cabinet includes a load switch, a chain trip mechanism and a fuse device. When the current exceeds the specified value, the fuse in the fuse device will blow the internal fuse with the heat generated by itself, and pop out the striker The chain release mechanism is triggered to finally open the load switch to achieve the purpose of protecting the safety of electricity consumption. [0004] The current fuse device has the following problems: [0005] (1) The trigger force loss is serious, and the trigger force cannot be transmitted reliably. [0006] (2) The moisture-proof effect is poor, which seriously affects the safety of...
