Abstract

The invention discloses a high-voltage disconnecting switch, and relates to the field of disconnecting switches. The high-voltage disconnecting switch aims at solving the problem of poor heat dissipation of the existing high-voltage disconnecting switch. The high-voltage disconnecting switch comprises a base, a push rod, a heat-dissipation component, a movable contact piece and fixed contacts, wherein a fixing sleeve is arranged on the base; a shaft sleeve is slidingly mounted in the fixing sleeve; insulating columns are mounted on the two sides of the upper end of the base; the push rod is arranged between the two insulating columns, and connected with a rotating shaft; the rotating shaft is embedded into the shaft sleeve in a sleeving manner; fixing columns are mounted at the upper endsof the insulating columns; the fixed contacts are mounted on the fixing columns, and connected by the movable contact piece; a sliding rail is arranged on the movable contact piece; a sliding shaft isslidingly mounted in the sliding rail; the push rod is connected with the sliding shaft; and the heat-dissipation component is fixed on the movable contact piece. The high-voltage disconnecting switch adopts multiple heat-dissipation fins, so that the high-voltage disconnecting switch has a good heat-dissipation effect; and the heat-dissipation fins are connected by elastic connection pieces to adjust spacings between the heat-dissipation fins, so that different heat-dissipation effects are achieved, and the high-voltage disconnecting switch is applicable to different high-voltage circuits.

Description

technical field [0001] The invention relates to the field of isolating switches, in particular to a high-voltage isolating switch. Background technique [0002] The isolating switch is a switching device that is mainly used to "isolate power supply, switch operation, connect and cut off small current circuits", and has no arc extinguishing function. When the isolating switch is in the off position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; current switching device. [0003] The high-voltage isolating switch is an isolating switch used in the electrical system of power plants and substations to ensure the safety of high-voltage electrical appliances and devices during maintenance work. The isolating switch will generate heat when it is powered on. However, the existing high-voltage isolating switches on the market lack heat dissipation structure design, which is not conducive to heat dissipa...
