摘　　要：本文以目前使用最广泛的油塞式取油阀作为取油对象,针对无人取油所需要的相关技术进行了研究。通过试验发现最小拧动力矩随拧紧力矩的增大呈非线性提升,且逐渐趋近于拧紧力矩。最后提出了开阀壳扳手及油阀旋拧端的相关设计,来实现取油过程的全自动化,给变压器无人取油技术提供了建议与指导方向。The paper takes the most widely used oil plug type oil pickup valve as the object of oil pickup, and studies the related technology required for unmanned oil pickup. It is found that the minimum unscrewing torque increases nonlinearly with the increase of the tightening torque, and gradually converges to the tightening torque. Finally,the design of the wrench for opening the valve housing and the screwing end of the oil valve is proposed to realize the full automation of the oil extraction process, which provides suggestions and guidance directions for the transformer unmanned oil extraction technology.
