| 一、产品概述 Genera | |||||
| XKM/HY系列电能计量联合接线盒是在原生产的XKM/DFY1、2和XKM/PJ1、2型电能计量联合接线盒的基础上最新开发的产品。为配合电力部门采用标准接线及安全测试创造了良好的条件。 该产品是电能计量装置标准接线盒中的新一代接线盒，也适用于额定电压至660V、额定电流至20A的二次回路中，作为带负荷情况下安全调换成现场检验电能表、电气仪表、继电保护等电气设备之用，确保了人身操作安全，对提高了现场工作效率提供了保障。 | |||||
| XKM/HYtype energy-measuring combined terminal blocks are the latest products developed on the basis of former XKM/DFY1 and 2 type and XKM/PJ1 and 2 type energy measuring combined terminal blocks. The product provides favorable conditions for standard connection and safe test of electric power department. As for the standard terminal block boxes of the energy measuring device, the product is a new generation of terminal block, suitable for the circuit of rated voltage 660V and rated current 20A, performing the safe adjustment and field test of watt-hour meter, electric meter, relaying protection device, etc. under on-load conditions, to make sure the safety of human operation and provide the guarantee of improving the field working efficiency. | |||||
| 二、结构特点 Structural features | |||||
| 1、该产品全部采用了高分子聚碳酸酯材料注制而成。因而它具有阻燃性，耐高温，不吸水、潮 湿 、 绝抗缘性能好，抗冲击、不易碎裂、抗老化等多种优质特性。结构合理，色泽鲜， 外 形 美艳观。各相电压、电流具有相序颜色标志，既方便联合接线，又可避免因相序错 而 造 成接计量错误。带封印螺丝，可防窃电。 2、采用透明盖板，既能观察到接线盒内部的工作状态；既直观，又安全可靠；有的底板和外壳全部采用透明材料，既安装方便，又可透视到盒内所有导电部件，达到了检修方便、安全用电的目的。 3、盒内各回路中专门设置了测试孔，十分方便插入测试笔，极大地方便了安全检查和测试。 1、The product adopts high-molecular polycarbonate material and is made by injection moulding process, therefore, it has the advantages such as flame retardant, high temperature resistance, no water absorption, moisture resistance, favorable insulation, impact resistance, no easy to crack, aging resistance and so on. It is featured with reasonable structure, vivid color and nice appearance. In addition, the voltage and current of each phase has the mark of phase sequence color, so it is easy for combined connection and avoids the measurement error that is caused by wrong phase sequence. It is fixed with sealing screw that is helpful for preventing the electricity being stolen. 2、Because the cover plate is made of transparent material, it not only can take convenience for viewing the operation state of terminal block inside, but also can facilitate the installation and make sure the reliability of connection. And, some bedplates and enclosures are also made of transparent material, it is very easy for installing, besides, the conductive parts in the terminal block may be watched, so as to achieve the goal of convenient maintenance and safe power utilization. 3、Some test holes are equipped at the circuits, which can facilitate the insertion of test pen and take the great convenience for safety examination and test. | |||||
