Disconnecting switch with heat dissipation vents

Abstract

The invention discloses a disconnecting switch with heat dissipation vents, comprising a switch housing. The lower end of an inner cavity of the switch housing is fixedly mounted with a connector clamp, the front and rear sides of the outer surface of the switch housing are provided with a heat dissipation vent respectively, the top end of the switch housing is movably connected to a rotating handle by a movable shaft, and the bottom of the left side of the outer surface of the switch housing is fixedly connected whit a fastener. A connecting system is formed by the rotating handle and the connector clamp, so that the entire line is energized. When a short circuit current occurs in the circuit, a fusible core in the rotating handle can quickly blow and cut off the circuit, and the fusing heat of the fusible core is quickly dissipated from the heat dissipation vents, avoiding the possibility of fire, ensuring the safety of people and ensuring the safe operation of the disconnecting switch. The problem that a large amount of heat is generated when the fusible core in the disconnecting switch is blown, and a great threat is caused to people's electricity safety if this heat is not discharged in time is solved.

Description

technical field [0001] The invention relates to the technical field of isolating switches, in particular to an isolating switch with cooling vents. 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, but the existing isolating switch only has a single function of connecting or cutting off the small current circuit. When the fuse core in the isolating switch is fused, a large amount of heat will be generated. If the heat is not discharged in time, it will pose a great threat to people's electricity safety. For this reason, we propose a disconnector with cooling vents. Contents of the invention [...

Problems solved by technology

[0003] The purpose of the present invention is to provide an isolating switch with cooling vents, which has the advantage of quickly discharging the heat generated when the fuse core is blown, and solves the problem that a large amount of heat will be generated when the fuse core in the isolating switch is blown. If it is not discharged in time, it will pose a great threat to people's electricity safety.
