Abstract

The invention belongs to the field of high-voltage electrical switching equipment, and in particular relates to a high-voltage isolating switch for a railway locomotive. The high-voltage isolating switch comprises an isolating switch pole, a bus connection plug, a cable shoe, a sleeve, a permanent magnet actuator, an insulation pull rod and an installation plate; a vacuum arc extinguishing technology is adopted; a solid insulation technology is adopted in an insulation layer; an insulation material is made from epoxy resin or EPDM; a uniform ring is adopted at the internal joint; and a semi-conductive shielding technology is adopted on the external surface. The high-voltage isolating switch disclosed by the invention is standardized in interface, good in universality, easy to extend, smallin product volume and high in security.

Description

technical field [0001] The invention belongs to the field of high-voltage electrical switchgear, in particular to a high-voltage isolating switch for railway locomotives. Background technique [0002] With the continuous development of China's economy, railway transportation is playing an increasingly active role in the important means of transportation in China. In the future, China's railway construction will enter a golden period. With the arrival of the peak of railway construction, the market demand is increasingly strong. Conventional railway switchgear is gas-insulated metal-enclosed switchgear, which has problems such as large volume, risk of arcing, heavy weight, great influence from the external environment, and inconvenient use. Contents of the invention [0003] The problem to be solved by the present invention is to provide an electrified locomotive isolating switch, which solves the problems that the existing isolating switch occupies a large volume, is heav...
