产品用途 Product purpose

防倒电保护装置适用于1kV及以下低压绝缘配电线路在联络开关两侧，分支杆、耐张杆接头处及有可能反送电的分支线点(或有安装三相动力表的分支线)的导线上应设置停电工作接地点的接地保护。

The anti-reverse power protection device is suitable for 1kV and below low-voltage insulated distribution line on the sides  of the connection switch, the branch rod, the joint of the tension rod and the branch point of the possible power  transmission (or the branch line with the three-phase power meter).

产品特点  Product feature 

1、安装防倒供电装置，既便捷了低压线路检修、抢修的工作，也避免每次装设接地线时重复对导线进行剥皮及包扎的麻烦，同时杜绝自备发电上网或误合开关等错误操作，造成人身伤害事故的发生，同时更加规范低压线路安全接地方式，防止乱接地现象而引起不必要的事故发生，极大提升了安全系数。

1. The installation of anti-reverse power supply device, that is, to facilitate the low-voltage line maintenance, emergency  repair work, avoids the installation of the wire when the ground wire, and prevent the self-provided power generation or  switch and other wrong operation, resulting in personal injury accidents, as well as more standardize the safety grounding  mode of low-voltage lines to prevent random grounding phenomenon caused by unnecessary accidents, which greatly  improves the safety factor. 

2、产品采用双扣环结构，在检修时用，检修人员站在地上拿起令克棒接地棒(或其它类似工具)即可进行检修操作，整个工作过程中工作人员可站在地上或在安全距离进行操作，无需爬高，操作更加方便，更加安全。

2. The product adopts double retaining ring structure, and during maintenance, the maintainer standing on the ground to  pick up the G bar ground rod (or other similar tools) can be carried out maintenance operations. In the whole work process,  the staff can stand on the ground or operate at a safe distance, and does not need to climb, the operation is more  convenient and safe. 

3、壳体上半体与下半体之间及本体部与连接管部之间采用迷宫槽防水结构，并在迷宫槽内设有柔性密封垫，同时导线部分采用防水胶带进行密封与内壳体多点结构配合，绝缘性能佳。

3. The labyrinth groove waterproof structure is used between the upper and lower halves of the shell and between the body  part and the connecting tube part, and a flexible gasket is provided in the labyrinth groove, while the conductor part is  sealed by a waterproof tape with the inner shell multi-point structure to match with the best insulation performance.

4、设有导线保护金箔，采用采用特殊导电胶，导电性能好，密封性强，与绝缘胶布配合大大增强裸导体的防氧化性能，提高电缆的寿命;

4. The product is equipped with conductor protection gold foil, special conductive adhesive with good conductivity and  strong sealing, which greatly enhances the anti-oxidation performance of the bare conductor in conjunction with the  insulating adhesive tape and improves the life of the cable;

5、产品能重复使用，与导线同寿命，并极大地提高了工作效率，属环保节能性产品;产品性能稳定接触，免维护，免检修，大大减少维护费用成本。

5. The product can be reused, the same life with the wire, and greatly improve the efficiency of the work, which is an  environmentally energy-saving products; and the product performance is stable contact, maintenance-free, greatly reducing  the cost of maintenance costs.
