Hot switchgear refers to a device that can control the thermal contact or thermal separation between two objects. The most common are gas switches, mechanical switches, superconducting switches, and magnetic heat switches.
E.g:
1.Gas switch
Two untouched objects, if they are in a high vacuum environment, have very poor heat transfer to each other, and are in a state of thermal separation. After a small amount of helium is charged, heat transfer between the two objects is performed between the two objects. Thermal contact is achieved, which acts as a thermal switch.
2. Mechanical switch
There are two types of clamps and flats. When the B object is clamped by a pliers that is thermally connected to the A object, it is thermally connected, and the pliers are thermally separated when released. The flat plate can be thermally connected or separated from the B object by a telescopic tube or a telescopic joint of the Wilson joint. In order to reduce the thermal resistance at the time of contact, a high thermal conductivity metal plate such as silver, gold or copper should be welded at the contact.
