| 一、產品概述 Genera | ||||||||||||||||
| 根據電力部城網改造規劃，為了改善居民生活用電條件，逐步實行"一戶一表”制的要求，本廠研制生產了XKM/JHD系列專用接線盒產品。該產品經全國十多個省、市、自治區的近百個單位使用，用戶普遍反映：安裝該接線盒后，既操作方便，又確保了接線的可靠，達到了安全用電的目的。深受電能計量工作者的歡迎，對電力系統推行"一戶一表”制與電能計量裝置的標準化和規范化管理起到了積極的作用，由浙江省科協等四單位認定為浙江省高質量科技產品，電力工業局推薦使用。 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、產品用途 Application | ||||||||||||||||
| 采用該接線盒后，可將進戶線與進表線分開，解決了以往進戶線處并接的問題，相線接線盒蓋板還可鉛封，以防竊電；零線接線盒可重復接地，符合電能計量規范中"專用、封閉”的原則及《浙江省電力工業局一戶一表實施規范化意見》中有關接線的規定。適用于"一戶一表”制集表式計量箱 (也稱公房住宅一戶一表制電表箱) 的配套以及直接用于舊城老區"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、結構特點 Structural features | ||||||||||||||||
| 該系列產品由于采用美國進口的高分子聚碳酸酯材料注制而成，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、耐高溫等特性。接線螺釘采用復合槽組合工藝，一字十字二種螺絲刀通用，因而體積小，容量大，耐壓高，結構合理，色澤鮮艷，外形美觀，深受廣大用戶歡迎。 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. | ||||||||||||||||
