Abstract

The invention relates to a high-voltage DC relay, belonging to the technical field of a relay. The high-voltage DC relay comprises an upper press cover, a shell body, a contact bin, an outer shell, a static contact, a fixed iron core, a movable contact assembly and a framework, wherein the upper press cover is matched with the shell, the contact bin is assembled with the outer shell, the movable contact assembly is arranged on the framework, the contact bin is assembled on the movable contact assembly, and the fixed iron core is arranged in the framework. The high-voltage DC relay has the advantages of reasonable structure, simplicity in production process, high working voltage, long service lifetime, safety and reliability.

Description

technical field [0001] The invention relates to a relay, in particular to a high-voltage direct current relay, which belongs to the technical field of relays. Background technique [0002] The increasing development of electric and hybrid vehicles, fuel cells, inverters and solar power generation systems makes it necessary to provide compact relays with high voltage DC loads. [0003] In the existing high-voltage relays, the working voltage is low, and the sealed cavity uses a vacuum medium to achieve the high-voltage resistance function between the electrodes. When the working voltage of the relay is high, the vacuum medium will generate harmful X-rays to the human body, so the sealed cavity The vacuum medium is used to achieve the high-voltage resistance function between the electrodes. This method has certain limitations on the working voltage of the relay and cannot fully meet the user's requirements. [0004] The publication date is April 22, 2015, and the Chinese pate...
