An insulation and heat conduction device applied to high-voltage optical communication equipment

Abstract

The embodiment of the present application discloses an insulating and heat-conducting device applied to high-voltage optical communication equipment, including: a bracket, a cover plate, a plurality of connecting posts, and at least one ceramic insulating tank for installing power devices. One ends of the plurality of connecting columns are jointly fixed on the cover plate, and the other ends are jointly fixed on the bracket. In the embodiment of the present application, a bracket, a cover plate, a connecting column and a ceramic insulating tank are used to jointly constitute the installation structure of the power device. The ceramic insulating tank is the main equipment of the structure, using a new high-performance ceramic material, which has good machinability, high material strength, high thermal conductivity and insulation performance. Encapsulate the power device inside the ceramic insulating tank, which can achieve electrical isolation and heat conduction at the same time. It can not only prevent the power device from discharging and creeping to the external conductor when it is working, but also use the copper seat to conduct the heat emitted by the power device to the ceramic insulating tank. and conduct to the outside world through the ceramic insulating tank to realize heat dissipation.

Description

technical field [0001] The present application relates to the technical field of insulation and heat conduction of high-voltage equipment, and in particular, to an insulation and heat-conduction device applied to high-voltage optical communication equipment. Background technique [0002] In the field of transoceanic communication, some optical communication devices are deployed on the seabed, so they can only dissipate heat through heat radiation and heat conduction. With the development of communication technology, the power of each power device in optical communication equipment is getting higher and higher, and the heat generation is getting larger and larger, and some submarine optical communication equipment needs to use high-voltage power supply to ensure that the internal power devices can work normally. Therefore, the installation structure of optical communication equipment is required to have high heat dissipation performance and insulation performance. [0003] A...
