Under the combined action of the fixing band, the electric tracing band, the stainless steel band, the heat preservation material, the heating box, the heat conduction pipe, the heating wire and the temperature sensor, the high-voltage switch can normally operate in an ultralow-temperature environment and cannot be affected by temperature, a protective layer is additionally arranged on the surface of the high-voltage switch, the insulation effect can be achieved, and the service life of the high-voltage switch is prolonged. And cold air is prevented from entering the high-voltage switch, the lead screw rotates to drive the translation block on the lower portion to be far away, so that the ventilation opening is opened, and along with rotation of the vertical rotating shaft, air enters the ventilation opening, passes through the ventilation cavity and is discharged towards the cavity, and air circulation is accelerated.

Description

technical field

[0001] The invention relates to the field of electric power technology, in particular to an ultra-low temperature protection device for a high-voltage switch. Background technique

[0002] High-voltage switch refers to the power generation, transmission, distribution or power conversion of the power system. It is usually installed in a high-voltage switchgear. The switchgear has functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, and bus connection. , metallurgy and steel rolling, light industry textile and residential quarters, high-rise buildings and other places.

[0003] At present, the existing ultra-low temperature protection devices for high-voltage switches on the market are mainly improved for the damage of high-voltage switch insulation. For example, a kind of ultra-low temperature protection device for high-voltage switches provided by Chinese patent CN202797741 U has the ability to prevent the insulation gas ...
