| 一、产品概述 Genera |
XKM/PJ1、2 型电能计量联合接线盒 (也称DFYlB、DFY2B接线盒) 是根据全国电能计量装置统一设计组专家们的意见，在原生产的XKM/PJ1 、 2型电能计量联合接线盒的基础上最新研制的。为配合电力系统采用标准接线及实施《电能计量装置检验规程》创造了有利的条件。
该产品是电能计量装置标准接线中的专用接线盒，也适用于额定电压至660伏、额定电 流至20安的二次回路中，作在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，提高了现场工作效率，对提高计量正确性起到了积极的作用。 |
XKM/PJ1 、 2 type energy measuring terminal blocks are developed on the basis of former ones acco-rding to the suggestion from relevant experts of national electric power bureau.This provides a favorable environment for adopting standard wiring.
This products is specialy applied for standard wiring of energy measuring equipment, It is also suitable for secondary circuit of rated voltage up to 660V and rated current up to 20A. It is used to change or inspect the electric equipment such as energy meter, electric instrument and relaying protection equipment under on-load circumstance. It guarantees operater personal safety and improves fieldwork efficiency. It plays a positive role in improving the measuring correctness. The products can always receive favorable comments in the power system field.

| 二、结构特点 Structural features |
XKM/PJ1、2型电能计量联合接线盒产品为国内首创，质量优良，由于采用了美国进口的高分子聚碳酸酯材料注制而成，色泽鲜艳，外型美观，它具有抗冲击强度高，不易碎裂；抗潮湿，绝缘性能好；抗老化、阻燃、耐高温；可在-40℃至+120℃范围内长期工作；接线镙钉采用复合槽组合工艺，一字十字二种螺丝刀通用。其电压回路采用一进三出，各相电压、电流具有相序标志，即方便联合接线，又可避免因相序接错而造成的计量错误，接线盒的盖板用两只可封印的螺丝固定，有利于防窃电工作。
XKM/PJ1 、 2 type energy measuring terminal block have excellent quality. It adopts high-molecular polycarbonate material imported from America. It has advantages of bright and elegant appearance, high impact resistance, moisture resistance, favorable insulation; ageing resistance, flame retardant and high temperature resistant. It can work at -40℃~+120℃ for long term. The screw adopts compound recess , which is suitable for flathead screwdriver and crossed screwdriver. The voltage circuit adopts one-inlet three-outlet, All phases are marked with phase sequence, which is not only convenient for combined wiring, but also can avoid measuring error caused by wiring wrong phase sequence. The Terminal block cover is fixed with two sealing screws, which is helpful to provent electictricity-theft. |
