Problems solved by technology
[0002] The existing relay realizes the on-off of the high-voltage circuit through the contact and disconnection of the dynamic and static contacts. However, arc discharge will occur between the dynamic and static contacts during the on-off process, and the high-temperature arc will cause the contacts to be ablated. , causing permanent scars, shortening the life of the contacts, especially in frequent on-off conditions, it will also cause the relay to heat up and burn out, and the structural reliability is low

The invention discloses a self-locking liquid metal contact long-life relay, which comprises a liquid tank, a tank cover, an insulating cover, an air bag, a first pin, an air pump, an electromagnet, a magnetic contact assembly, a spring, and a first connecting pipe , breaking seat and second connecting pipe; the tank cover and the tank form two metal liquid chambers filled with liquid metal; the insulating cover is fixedly installed on the tank cover, and the air bag is set in the metal liquid chamber; the air pump has a rodless chamber and There is a rod chamber; the rod chamber is filled with inert gas, and the rodless chamber communicates with the air bag; the magnetic contact assembly is connected to the output end of the air pump; the two ends of the spring are in contact with the magnetic contact assembly and the air pump respectively; In the breaking channel, the two ends of the first connecting pipe are connected to the liquid metal chamber and the breaking channel respectively, and the two ends of the second connecting pipe are respectively connected to the rod chamber and the breaking channel; the invention can greatly suppress the arc discharge and effectively avoid the formation of contacts Permanent scars improve the service life of the relay and make the structure more reliable.
Description
technical field [0001] The invention relates to a self-locking liquid metal contact long-life relay. Background technique [0002] The existing relay realizes the on-off of the high-voltage circuit through the contact and disconnection of the dynamic and static contacts. However, arc discharge will occur between the dynamic and static contacts during the on-off process, and the high-temperature arc will cause the contacts to be ablated. , causing permanent scars, shortening the life of the contacts, especially in frequent on-off conditions, it will also cause the relay to heat up and burn out, and the structural reliability is low. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned shortcomings, and provide a self-locking liquid metal contact long-life relay. [0004] To achieve the above object, the specific scheme of the present invention is as follows: [0005] A self-locking liquid metal contact long-life relay, ...
