Abstract

The invention discloses a disconnecting switch with a fusing indication lamp, comprising a switch housing. An upper end of an inner cavity of the switch housing is fixedly mounted with the fusing indication lamp, a lower end of the inner cavity of the switch housing is fixedly mounted with a wiring clamp, a fastener is fixedly connected to a bottom of the inner cavity of the switch housing, and lower ends at two sides of the outer surface of the switch housing are provided with heat dissipation vents. In the disconnecting switch, a connection system is formed by the wiring clamp and the fastener, so that the whole line is energized. When a short circuit current occurs in the circuit, a fusible core in a rotating handle can quickly blow and cut off the circuit, and the fusing heat of the fusible core is exhausted from the heat dissipation vents, avoiding the possibility of fire and ensuring the safety of people's use. Meanwhile, the fusing indication lamp lights up after the fusible core is blown, which serves as a safety indicator and solves the problem that the existing disconnecting switch has only a function of single connection or cutting off of the small current circuit but not the function of fusing indication.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to an isolating switch with a fuse indicating lamp. Background technique [0002] The isolating switch is mainly used for isolating power supply, switching operation, and a switching device used to connect and cut off small current circuits. The isolating switch that people often say generally refers to a high-voltage isolating switch, that is, a rated voltage above one thousand volts. The isolating switch is the most widely used electrical appliance in the high-voltage switchgear. , we propose an isolating switch with a fuse indicator. Contents of the invention [0003] The purpose of the present invention is to provide an isolating switch with a fuse indicating lamp, which has the advantages of fuse indicating, and solves the problem that the existing isolating switch only has a single function of connecting or cutting off a small current circuit, but has no function of indica...
