技术领域 technical field
本发明涉及一种回路电阻测试轻质复合绝缘杆。 The invention relates to a lightweight composite insulating rod for testing loop resistance.
背景技术 Background technique
高压试验是电气试验的重要组成部分，也是保障电力系统安全有效运行的关键部分。在高压试验的过程中，保障试验人员以及设备的安全是首要任务，特别是人身安全。传统回路电阻测试绝缘杆与测试线采用外部搭接的配合方式。该方式中，由于绝缘杆及试验线较重、测试线自然倾斜等将对绝缘杆产生较大的水平拉力，另外，风力牵引对绝缘杆的稳定性也有较大影响。传统回路电阻测试绝缘杆设计及工艺上的不完善使得高压试验过程中存在安全隐患，近几年多有发生由此引发的人身电弧灼伤事故。另外，在电力系统生产现场实际使用时，经常会出现高空设备表面氧化层较厚需要摩擦去氧化层的情况，现行使用的接线钳接触面较平滑、摩擦太小，使用不方便。在实际生产现场，操作人员亦感觉操作不方便，因此有必要对传统回路电阻测试绝缘杆进行改进。 High voltage test is an important part of electrical test, and also a key part to ensure the safe and effective operation of power system. During the high-voltage test, the safety of test personnel and equipment is the top priority, especially personal safety. The traditional loop resistance test insulation rod and test line adopt the external lap joint mode. In this method, due to the heavy weight of the insulating rod and the test line, and the natural inclination of the test line, a large horizontal pulling force will be generated on the insulating rod. In addition, the wind traction also has a great influence on the stability of the insulating rod. The imperfection of the design and process of the insulating rod for traditional loop resistance testing leads to safety hazards in the high-voltage test process. In recent years, there have been many personal arc burn accidents caused by this. In addition, in the actual use of power system production sites, it often occurs that the oxide layer on the surface of high-altitude equipment is thick and needs to be rubbed to remove the oxide layer. The contact surface of the currently used wiring pliers is relatively smooth, the friction is too small, and it is inconvenient to use. In the actual production site, operators also feel that the operation is inconvenient, so it is necessary to improve the traditional loop resistance test insulation rod.

本发明结构合理，减小绝缘杆受试验线牵引力及风力作用的影响。测试用电流线直接浇筑在绝缘杆内部，形成导流体；测试用电压线从绝缘杆中间穿过，与绝缘杆成为同向，减少了测试线对绝缘杆产生的水平拉力以及风力对绝缘杆稳定性的影响；减轻了绝缘杆和试验线的总重量。由于导流铜导体浇筑在绝缘杆内部，导流铜导体表面不包裹绝缘层，绝缘杆外壁实现对外绝缘；测试线竖直、不倾斜，减小了测试所需试验线长度，从而可减轻绝缘杆和试验线的总重量。 The invention has a reasonable structure and reduces the influence of the insulating rod on the traction force of the test line and the wind force. The current wire for testing is directly poured inside the insulating rod to form a conductive body; the voltage wire for testing passes through the middle of the insulating rod and is in the same direction as the insulating rod, which reduces the horizontal tension of the testing wire on the insulating rod and the impact of wind on the insulating rod. Stability effects; reduced overall weight of insulating rod and test wire. Since the diversion copper conductor is poured inside the insulating rod, the surface of the diversion copper conductor is not wrapped with an insulating layer, and the outer wall of the insulating rod realizes external insulation; the test line is vertical and not inclined, which reduces the length of the test line required for the test, thereby reducing insulation. Total weight of rod and test wire.
通过将试验线浇筑在绝缘杆内壁上，减小试验线以及风力对绝缘杆的牵引力，一定程度上降低试验过程中绝缘杆和试验线的整体重量，以提高绝缘杆的稳定性，保障使用者的人身安全，满足了高压试验现场实际应用需求。 By pouring the test line on the inner wall of the insulating rod, the traction force of the test line and the wind on the insulating rod is reduced, and the overall weight of the insulating rod and the test line during the test is reduced to a certain extent, so as to improve the stability of the insulating rod and protect the user Personal safety, to meet the actual application requirements of the high-voltage test site.
