The utility model discloses a buried transformer, which comprises a transformer main body, a high-voltage terminal seat connected with an incoming cable and a low-voltage power supply terminal seat connected with an outgoing cable are arranged on the main body of the transformer, a sealing box is sealed and welded on the outer wall of the transformer main body, a high-voltage terminal seat and a low-voltage power supply terminal seat are arranged in the sealing box, and a sealing box is provided with a sealing for incoming and outgoing cables. The buried transformer of the utility model abandons the previous thick box body and directly seals and welds the sealed box on the transformer body. The incoming and outgoing cables are connected through the inlet and outlet of the sealed box and are sealed and connected with the high-voltage terminal seat and the low-voltage power supply terminal seat in the sealed box, thus realizing the electric connection without any further need of the high-voltage terminal seat and the low-voltage power supply terminal seat in the sealed box. Insulating waterproof material is poured for sealing, and the sealing box has a repair opening, which is convenient for checking and repairing the lines in the sealing box in the future.

一种地埋式变压器
本技术涉及一种变压器,尤其是一种地埋式变压器。
技术介绍
现有技术中,地埋式变压器包括密封箱体,变压器主体设置在密封箱体内,在密封箱体上设置有连接高压接电端座的一次接线端和连接低压供电端座的二次接线端,一、二次接线端分别连接进、出线电缆并通过浇注绝缘防水材料实现密封绝缘,该种变压器体积庞大,不易运输且内部线路设置复杂;另一方面,被接线端被密封浇注后难以进行后续的检修,且绝缘防水材料已不符合现今的环保标准,所以,需对地埋式变压器进一步的研究改进。
技术实现思路
为了克服现有技术的不足,本技术提供一种结构轻便、易于检修且密封性良好的地埋式变压器。本技术解决其技术问题所采用的技术方案是:一种地埋式变压器,包括变压器主体,所述变压器主体上设置有连接进线电缆的高压接电端座及连接出线电缆的低压供电端座,所述变压器主体外壁上密封焊接有密封箱,所述高压接电端座和低压供电端座设置在密封箱内,所述密封箱上设置有供进、出线电缆密封穿接的进线口和出线口,所述密封箱上还设置有检修口。所述进线口处设置有进线电缆密封装置,其包括电缆法兰A、电缆胶垫A、电缆法兰B、电缆法兰C、电缆胶垫B和电缆法兰D。所述出线口处设置有出线电缆密封内法兰、出线电缆密封胶垫和出线电缆密封外法兰。所述检修口通过检修口密封法兰、检修口密封胶垫及检修口密封盖板配合将检修口封堵。本技术的有益效果是:本技术的地埋式变压器摒弃了以往厚重的箱体,直接在变压器本体上密封焊接有密封箱,进、出线电缆连通过密封箱上的进、出线口密封穿接并与密封箱内的高压接电端座和低压供电端座实现电连接,无需再浇注绝缘防水材料进行密封 ...
