一、概述
JDX系列携带型短路接地线是按《带电作业用携带型接地和接地短路装置》中华人民共和国电力行业标准(DL-T879-2004),结合广大电力工作者对接地线的改进要求,由本公司科研人员及电力系统工程技术人员共同开发的一种新型产品。JDX系列携带型短路接地线于2000年6月通过电力部安全工器具质量监督检测测试中心的型式试验,所有试验项目全部合格。
 
二、结构特点
1. 由导线端线夹、短路线、汇流夹、接地线、接线鼻、接地端线夹或临时接地极以及接地操作棒等组成。
2. 导线端和接地端的线夹采用优质铝合金压铸,与其配套的紧固件金属均经镀镍处理。
3. 接地操作棒采用绝缘性能与机械强度俱佳的高级环氧树脂、玻璃纤维精制而成,同时对操作手柄加装硅橡胶护套,合牢固,绝缘更为安全可靠。
4. 短路线与接地线采用多股优质软铜线绞合而成,并外覆柔软、耐高温的透明绝缘护层,可以防止使用中对接地铜线的磨损,确保作业人员在操作中的安全。
5.接线鼻和汇流夹与接地铜线及外护套采用压接新工艺,软连接可有效地防止使用时连接处铜线断股,提高了接地线的可靠性和使用寿命。

First, an overview
 
JDX Series Portable Short Circuit Grounding Wire is a new type of product developed jointly by our company's scientific researchers and power system engineering technicians in accordance with the "Portable Grounding and Grounding Short Circuit Device for Live Operation" Power Industry Standard of the People's Republic of China (DL-T879-2004), combined with the improvement requirements of electric power workers for grounding wire. . JDX Series Portable short-circuit grounding wires passed the type test of the Quality Supervision and Testing Center of Safety Instruments of Ministry of Power in June 2000, and all the test items were qualified.
 
 
 
Two, structural characteristics
 
1. It is composed of conductor terminal clamp, short-circuit wire, confluence clamp, grounding wire, connection nose, grounding terminal clamp or temporary grounding electrode and grounding operation bar.
 
2. The clamps of conductor end and grounding end are made of high-quality aluminum alloy by die casting, and the fasteners matched with them are all nickel-plated.
 
3. The grounding operation rod is made of high-grade epoxy resin and glass fiber with excellent insulation and mechanical strength, and silicone rubber sheath is added to the operation handle to ensure a firm fit and a safer and more reliable insulation.
 
4. The short-circuit wire and the ground wire are made of multi-strands of high-quality soft copper wire, and covered with a soft and high-temperature transparent insulating layer, which can prevent the wear and tear of the ground copper wire in use and ensure the safety of the operators in operation.
 
5. The new technology of pressing connection is adopted between the connection nose and the catchment clip, the grounding copper wire and the outer sheath. The soft connection can effectively prevent the broken copper wire at the connection, and improve the reliability and service life of the grounding wire.
 
 
 
Three. Classification and model description
 
According to the function and structure of grounding rod,
 
JDX series short-circuit grounding wires are classified according to the difference between the clip of the operation bar and the short-circuit grounding guide wire.
