Description
Technical Field
The invention relates to a fuse fault processing device.
Background
The drop-out fuse is a short-circuit protection switch most commonly used for 10kV distribution line branch lines and distribution transformers, has the characteristics of economy, convenience in operation, strong outdoor environment adaptability and the like, is widely applied to the primary side of the 10kV distribution line and the distribution transformers, and is used for protection and wire inlet equipment switching and switching operation. Faults associated with drop-out fuses occur occasionally due to inherent quality problems or the effects of inclement weather, and most faults are manifested as upper and lower lead breaks or damage to the body.
At present, the fault processing mode of the drop-out fuse can be divided into the following two processing modes except that the fuse wire is fused and the fusion tube can be replaced by an operating rod:
and (5) isolating the fault point and processing power failure. The processing mode can effectively reduce the safety risk during processing, ensure personal safety, increase the power failure time and reduce the power supply reliability.
And carrying out uninterrupted power supply processing through the live working vehicle. This mode adopts live working car to handle can produce comparatively expensive expense, utilizes live working car to handle simultaneously often can be restricted to on-the-spot road condition and weather factor.

Detailed Description
A drop-out fuse fault bypass processing device comprises an assembled processing device 1, wherein two ends of the assembled processing device are respectively connected with an upper replaceable lead wire 2 and a lower replaceable lead wire 3; the assembled processing device consists of a protective tube and a fuse wire and serves as a fuse wire tube; the upper and lower replaceable lead wires are respectively connected with an upper lead wire 4 and a lower transformer 5; during operation, the current is introduced into the transformer through the upper replaceable lead, the assembled processing device and the lower replaceable lead, so that the fault fuse is bypassed, a bypass effect is achieved, the fault fuse is overhauled, once overload or short-circuit fault occurs to the circuit again, the current passing through the fuse tube exceeds fusing current, the fuse wire is fused, the circuit is cut off, and an overcurrent protection effect is achieved.
The upper and lower parts of the assembled processing device are respectively provided with a bolt port, the bolts are installed and fixed in advance, and the upper and lower replaceable lead wire end parts are connected with the assembled processing device through the bolts after being provided with the wire pressing noses.
The invention connects two ends of the fault fuse 6 through a small bypass system which can be installed in an electrified way so as to realize the rapid processing of the fault. The invention is equipped with a special fastening connection device for the lead in order to realize the reliable connection of two ends of the fault fuse, and simultaneously, the invention is provided with a protection device to ensure that a bypass system on the connection has a short-circuit protection function. When the drop-out fuse breaks down, the line can not supply power normally. At the moment, the upper lead and the lower lead of the bypass processing device are connected with two ends of the fault fuse, so that the bypass effect is achieved, and normal power supply of a line is realized. Under the normal working condition, the fuse wire penetrates through the protection tube, and the circuit supplies power normally; when the fault occurs again, the fuse wire is fused, and the safety of the line is ensured. The device is provided with a fastening and connecting device special for a lead for realizing reliable connection of two ends of a fault fuse. Meanwhile, the device is provided with a protection device, and a connected bypass system is ensured to have a short-circuit protection function.
