| 一、产品概述 Genera | ||||||||||||||||
| 根据电力部城网改造规划，为了改善居民生活用电条件，逐步实行"一户一表”制的要求，本厂研制生产了XKM/JHD系列专用接线盒产品。该产品经全国十多个省、市、自治区的近百个单位使用，用户普遍反映：安装该接线盒后，既操作方便，又确保了接线的可靠，达到了安全用电的目的。深受电能计量工作者的欢迎，对电力系统推行"一户一表”制与电能计量装置的标准化和规范化管理起到了积极的作用，由浙江省科协等四单位认定为浙江省高质量科技产品，电力工业局推荐使用。 In order to improve residential electricity consumption condition, our company develops XKM/JHD series terminal block .This kind of terminal block enables the operation to be more convenient, and also guarantees reliable connection, and finally reaches the aim of safety in utilizing electric energy. This products get high appreciation from the energy measuring operators one-meter”and standardization of energy measuring devices as well as standardizedmanagement. The products are also honored as national high-quality technological products and are recommended for application by national electric power bureau. | ||||||||||||||||
| 二、产品用途 Application | ||||||||||||||||
| 采用该接线盒后，可将进户线与进表线分开，解决了以往进户线处并接的问题，相线接线盒盖板还可铅封，以防窃电；零线接线盒可重复接地，符合电能计量规范中"专用、封闭”的原则及《浙江省电力工业局一户一表实施规范化意见》中有关接线的规定。适用于"一户一表”制集表式计量箱 (也称公房住宅一户一表制电表箱) 的配套以及直接用于旧城老区"合表制”的改造。 Application of this terminal block enables house service wire to be separated from meter ser vi ce wi re, whi ch solves the problem of parallel connection. Terminal block cover can be sealed to prevent electricity theft ; Neutral line terminal block can be earthed repeatedly. It is in conformity with the"special, sealed”principle standardization of one-household one-meter. The products are applied in"one-household one-meter”electric energy metering box. | ||||||||||||||||
| 三、结构特点 Structural features | ||||||||||||||||
| 该系列产品由于采用美国进口的高分子聚碳酸酯材料注制而成，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、耐高温等特性。接线螺钉采用复合槽组合工艺，一字十字二种螺丝刀通用，因而体积小，容量大，耐压高，结构合理，色泽鲜艳，外形美观，深受广大用户欢迎。 This series of terminal block adopt high-molecular polycarbonate material imported from America. I t h a s a d v a n t a g e s o f high impact resistance, moisture resistance, favorable insulation; ageing resistance, flame retardant, high temperature resistant, etc. The binding screw adopts compound recess , which is suitable for flathead screwdriver and crossed screwdriver The products are popular due to compact volume, large capacity, high withstand voltage, reasonable structure, and elegant appearance. | ||||||||||||||||
