The utility model discloses a novel connection structure for high and low voltage side clamps of transformers, which comprises a pull screw and an insulating sheath; a pull screw includes an outer pull screw, an inner pull screw and a side pull screw; a high pressure side clamp and a low pressure side clamp are connected with an outer pull screw at one end, an inner pull screw at the other end, and a side pull screw at both sides; The clamp and the low-pressure side clamp are collectively called clamps; the clamp is provided with through holes, the pull screw passes through the through holes of the clamp, and the contact surface between the pull screw and the through holes of the clamp is provided with an insulating sheath. The utility model completely insulates the high and low voltage side clamps, and the high and low voltage side clamps are not in equipotential state, and the supporting parts are changed into pull screw, and the pull screw is non-magnetic conductive material, thereby reducing the circulation current and the additional loss caused by magnetic leakage. At the same time, the magnetic line through the pull screw is obviously less than that of the support, which reduces the magnetic leakage area. In addition, the support is changed to the pull screw, which is more convenient for processing and installation.

新型变压器高低压侧夹件连接结构
本技术涉及一种新型变压器高低压侧夹件连接结构,属于变压器类产品制造技术。
技术介绍
随着变压器产品市场竞争的日益激烈,产品的价格在很大程度上起到了关键作用。在保证产品性能水平前提下,如何降低产品的设计成本,是各产品制造厂首要解决的难题。传统的110kV产品结构高低压侧夹件通过支撑件连接,高低压侧夹件保持等电位,绕组产生的漏磁在夹件支撑件中会产生较大的损耗。从而增加产品设计成本。
技术实现思路
针对以上不足,本技术提供了一种既能解决绕组产生的漏磁现象,又可降低产品的附加损耗,达到降低产品设计成本的新型变压器高低压侧夹件连接结构。本技术改变传统的铁芯夹件固定结构,采用拉螺杆结构,并采用绝缘护套,从而达到减少环流,减少漏磁带来的附加损耗的目的,提高产品的性能水平。为了解决以上问题,本技术采用了如下技术方案:一种新型变压器高低压侧夹件连接结构,其特征在于,包括拉螺杆和绝缘护套;所述的拉螺杆包括外拉螺杆、内拉螺杆、旁拉螺杆;高压侧夹件和低压侧夹件一端链接外拉螺杆,另一端连接内拉螺杆,两侧连接旁拉螺杆;高压侧夹件和低压侧夹件统称为夹件;夹件上设有通孔,拉螺杆穿过夹件通孔,拉螺杆与夹件通孔的接触面之间设有绝缘护套,作为本技术的另一种技术方案,所述的拉螺杆上与夹件相连的地方套有绝缘护套。作为本技术的优选方案,所述的拉螺杆采用不导磁材料。有益效果:本技术是将高低压侧夹件完全绝缘,高低压侧夹件不处于等电位状态,且支撑件改为拉螺杆,拉螺杆为不导磁材料,从而减少环流,减少漏磁带来的附加损耗。同时通过拉螺杆的磁力线明显比支撑件少,减少了漏磁面积,减少杂散损耗 ...
