Abstract

The invention discloses a 10KV high-voltage drop-out fuse temporary through-flow device with overcurrent protection, and the device comprises a clamping device and a safety device; two ends of the safety device are respectively arranged at two ends of the clamping device, and the lower end of the clamping device is communicated with a lower pile head of a drop-out fuse. The upper end of the clamping device is communicated with the upper pile head of the drop-out fuse, so the safety device can communicate the lower pile head and the upper pile head of the drop-out fuse to form a passage. Through cooperation of the clamping device and the safety device, a passage with a temporary conductive function is formed and clamped on the drop-out fuse to realize conduction of a circuit, so the problemof overlong power failure time caused by incapability of timely arrival of live-line repair personnel is solved, and convenience and quickness are realized.

Description

Technical field: [0001] The invention relates to the field of power supply and transformation maintenance, in particular to a temporary flow-through device for a 10KV high-voltage drop-out fuse with overcurrent protection. Background technique: [0002] Drop-out fuse is the most commonly used short-circuit protection switch for branch lines of 10kV distribution lines and distribution transformers. It is economical, easy to operate, and adaptable to outdoor environments. It is widely used in 10kV distribution lines and power distribution The primary side of the transformer is used for protection and equipment switching and switching operations. [0003] When the drop-out fuse has a power outage due to a fault, causing a power outage for the user, because one end of the drop-out fuse is charged, live repair personnel are required to come to replace the faulty equipment, and the power supply can only be restored after the replacement is completed. However, due to the relatively...
