| 一、產品概述 Genera |
XKM/PJ1、2 型電能計量聯(lián)合接線盒 (也稱DFYlB、DFY2B接線盒) 是根據全國電能計量裝置統(tǒng)一設計組專家們的意見，在原生產的XKM/PJ1 、 2型電能計量聯(lián)合接線盒的基礎上新研制的。為配合電力系統(tǒng)采用標準接線及實施《電能計量裝置檢驗規(guī)程》創(chuàng)造了有利的條件。
該產品是電能計量裝置標準接線中的專用接線盒，也適用于額定電壓至660伏、額定電 流至20安的二次回路中，作在帶負荷情況下安全調換成現(xiàn)場檢驗電能表、電氣儀表、繼電保護等電氣設備之用，確保了人身操作安全，提高了現(xiàn)場工作效率，對提高計量正確性起到了積極的作用。 |
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、結構特點 Structural features |
XKM/PJ1、2型電能計量聯(lián)合接線盒產品為國內首創(chuàng)，質量優(yōu)良，由于采用了美國進口的高分子聚碳酸酯材料注制而成，色澤鮮艷，外型美觀，它具有抗沖擊強度高，不易碎裂；抗潮濕，絕緣性能好；抗老化、阻燃、耐高溫；可在-40℃至+120℃范圍內長期工作；接線鏍釘采用復合槽組合工藝，一字十字二種螺絲刀通用。其電壓回路采用一進三出，各相電壓、電流具有相序標志，即方便聯(lián)合接線，又可避免因相序接錯而造成的計量錯誤，接線盒的蓋板用兩只可封印的螺絲固定，有利于防竊電工作。
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. |
