Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0019] refer to Figure 1-3 , a vacuum interrupter with high heat dissipation, including an external leakage shielding cover 1, a plurality of first protrusions 2 are fixedly connected to the outer side of the external leakage shielding cover 1, and the function of the first protrusions 2 is to increase the external leakage The surface area of ​​the shielding cover 1 in contact with the air speeds up the heat dissipation. The first protrusion 2 is integrated with the leakage shielding cover 1. The upper end of the leakage shielding cover 1 is fixedly connected with the first shell 3. The outer leakage shielding cover 1 The bottom end is fixedly connected with the sec...

Abstract

The invention relates to the technical field of vacuum arc-extinguishing chamber and in particular to a vacuum arc-extinguishing chamber with high heat dissipation. The vacuum arc-extinguishing chamber comprises an outer leakage shielding cover, wherein the bottom of a movable conductive rod is fixedly connected with a first contact; the outer side of the first contact is fixedly connected with afirst insulating sleeve; a first heat conducting mechanism is engaged with the first insulating sleeve at a side of a second protrusion; a fixed conductive rod is mounted in a second casing; a secondcontact is fixedly connected to the top of the fixed conductive rod; the outer side of the second contact is sleeved with a second insulating sleeve; a third protrusion is fixedly connected to the outer side of the second insulating sleeve above the second insulating sleeve; a second heat conducting mechanism is engaged with the second insulating sleeve at the outer side of the third protrusion; the bottom of the first contact is fixedly connected with a plurality of conductive protrusions; the upper surface of the second contact is provided with connecting grooves on one side of each conductive protrusion; the inner side of the outer leakage shielding cover is fixedly connected to a third heat conducting mechanism. The vacuum arc-extinguishing chamber is simple in structure and is worthyof promotion.

Description

technical field [0001] The invention relates to the technical field of vacuum interrupters, in particular to a vacuum interrupter with high heat dissipation. Background technique [0002] The vacuum interrupter, also known as the vacuum switch tube, is the core component of the medium and high voltage power switch. Its main function is to quickly extinguish the arc and suppress the current after the medium and high voltage circuit is cut off through the excellent insulation of the vacuum in the tube, so as to avoid accidents and accidents. It is mainly used in power transmission and distribution control systems. It has the characteristics of energy saving, material saving, fire prevention, explosion protection, small size, long life, low maintenance cost, reliable operation and no pollution. [0003] When the vacuum interrupter is used, it will generate a lot of heat. If the heat is not dissipated in time, the internal components may be damaged and cannot be used. The exist...
