Arc-free high-performance relay with adjustable natural on-off state and using method thereof

Abstract

The invention discloses an arc-free high-performance relay with adjustable natural on-off state, which comprises a first casing, a second casing, a cooling liquid tank and an elastic liquid bag; the second casing is arranged at the bottom of the first casing And form an accommodating space with the first housing, a hydraulic cylinder structure is provided in the accommodating space, the cooling liquid tank is fixedly connected to the bottom of the second housing and a cooling chamber filled with cooling liquid is formed between the second housing and the second housing. Cavity; the hydraulic cylinder structure includes a hydraulic chamber, a first piston, a moving electric contact rod and a static electric contact rod, a magnetic contact, a first insulating gasket ring, a second insulating gasket ring and a sealing insulating gasket; the elastic liquid bag is filled with normal temperature The bottom is a liquid sodium-potassium alloy, the elastic liquid bag is in an expanded state in a natural state, the elastic liquid bag is located in the cooling cavity, and the elastic liquid bag is connected with the hydraulic chamber; an electromagnet is also installed in the accommodation space; the present invention effectively avoids the occurrence of The arc discharge phenomenon is beneficial to prolong the service life of the relay, and the structure is more reliable.

Description

technical field [0001] The invention relates to an arc-free high-performance relay with adjustable natural on-off state. Background technique [0002] The existing relay will produce arc discharge phenomenon between the dynamic and static contacts during the on-off process. The high-temperature arc will ablate the contacts, shorten the service life of the relay, and cause the relay to heat up under frequent on-off conditions. In extreme cases, the relay is damaged 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 an arc-free high-performance relay with adjustable natural on-off state. [0004] To achieve the above object, the specific scheme of the present invention is as follows: [0005] An arc-free high-performance relay with adjustable natural on-off state, comprising a first casing, a second casing, a coolant tank and an elastic liquid bag; the se...
