Abstract

The invention discloses a synthetic fuse with hard shielding protective case, which consists of insulating column (1) and fuse with insulating case (2), wherein two ends of insulating column connects two ends of fuse and touching point separately; the pull-ring is fixed on the top of insulating case, whose two ends connect touching point with ground bar connecting lower touching point; the fuse contains two hard shielding protective case (3) on two ends of upper and lower insulating column; the hard shielding protective case contains two side-hinged half-case (31) with fuse shape; the semi-circle flute is set on the half case hinged connecting end; two half-case connects to form a chuckable column on two ends of insulating column; the screw-thread earhole is opened on the case surface in connection with bolt. The invention solves impoundment problem, which is reliable to operate and convenient to assemble.

Description

technical field [0001] The invention relates to a fuse tool for a power supply system, in particular to a fuse tool with a protective shield. Background technique [0002] Fuses are indispensable in power supply systems. The fuses used today generally include a fuse and an insulating support. The contacts at both ends of the insulating wire are respectively connected to the two ends of the insulating support. Generally, insulating cloth is used to wrap metal conductive joints. The shielding measures of the site can prevent its single-phase grounding and phase-to-phase short circuit, which will cause power outage accidents, and a certain safety distance must be ensured during construction to ensure the safety of construction personnel. However, there are many high-rise buildings in modern cities, and the situation between residential buildings is complicated, and the construction often cannot guarantee a sufficient safety distance. Moreover, due to the changeable climate, th...
