Description
技术领域 technical field
本实用新型涉及一种避雷装置，特别涉及一种变压器上使用的避雷装置。 The utility model relates to a lightning protection device, in particular to a lightning protection device used on a transformer.
背景技术 Background technique
10KV变压器的避雷器，特别是户外传统的安装位置基本上都是安装在电杆的上部或中部，申请号为02230852.0的实用新型公开了一种避雷器固定架，包括安装避雷器的固定套和连接板，该连接板的一端为上卡板，该连接板的另一端为下插板，所说的固定套内安装上卡板，在变压器上架上用螺栓安装固定架，该固定架的另一端为连接套，该连接套内安装所说的下插板。由于避雷器安装离地面较高，因此遇到较大雷电天气时，避雷效果不理想，造成停电。 The lightning arrester of a 10KV transformer, especially outdoors, is basically installed on the upper or middle part of the pole. The utility model with the application number 02230852.0 discloses a lightning arrester fixing frame, including a fixing sleeve and a connecting plate for installing the lightning arrester. One end of the connecting plate is the upper clamping plate, and the other end of the connecting plate is the lower inserting plate. Cover, the said lower board is installed in the connecting sleeve. Since the lightning arrester is installed higher than the ground, the lightning protection effect is not ideal when encountering a large lightning weather, resulting in a power outage.
发明内容 Contents of the invention
本实用新型的目的旨在于克服现有技术的缺陷，提供一种避雷效果好、安装方便不增加装置成本的变压器避雷装置。 The purpose of the utility model is to overcome the defects of the prior art and provide a transformer lightning protection device with good lightning protection effect, convenient installation and no increase in device cost.
本实用新型所述的变压器避雷装置，由变压器和避雷器构成，避雷器与变压器的箱体固定连接，接地引线与地面连接。 The transformer lightning protection device described in the utility model is composed of a transformer and a lightning arrester, the lightning arrester is fixedly connected to the box body of the transformer, and the grounding lead is connected to the ground.
本实用新民述的变压器避雷装置，当线路感应雷电时，避雷器安装在变压器的箱体上，能尽快把雷电压引入大地以确保变压器的安全正常运行，而避雷器安装在变压器的箱体上，相对于传统的安装方法，避雷器离地面最近，避雷器的接地引下线的直流电阻也最小，从而避雷的效果也最好， 经在云南省几家矿山变电所的实验安装证实，该装置能免有效地提高避雷器保护变压器的效果，使变压器相对更能安全运行，与此同时，相对于传统的装置，本实用新型总的材料和工时费仅为原来的1/10，由原来的高空作业变为现在的地面作业，提高了作业的安全性。本实用新型避雷效果好，安装方便。 The transformer lightning protection device described in the utility model, when the line induces lightning, the lightning arrester is installed on the box body of the transformer, and the lightning voltage can be introduced into the ground as soon as possible to ensure the safe and normal operation of the transformer, and the lightning arrester is installed on the box body of the transformer, relatively Compared with the traditional installation method, the arrester is the closest to the ground, and the DC resistance of the grounding downconductor of the arrester is also the smallest, so the effect of lightning protection is also the best. It has been confirmed by the experimental installation in several mine substations in Yunnan Province that the device can avoid Effectively improve the effect of the lightning arrester to protect the transformer, so that the transformer can run relatively more safely. At the same time, compared with the traditional device, the total material and man-hour cost of the utility model is only 1/10 of the original one. For the current ground operations, the safety of operations has been improved. The utility model has good lightning protection effect and convenient installation.
