GB/T 18487.2-2017電動(dòng)汽車傳導(dǎo)充電系統(tǒng) 第2部分:非車載傳導(dǎo)供電設(shè)備電磁兼容要求

GB/T 18487的本部分規(guī)定了為電動(dòng)汽車非車載傳導(dǎo)充電的電動(dòng)汽車供電設(shè)備(以下統(tǒng)稱為供電設(shè)備)的電磁兼容要求。供電設(shè)備的供電電源額定電壓大值為1 000 V AC或1 500 V DC，額定輸出電壓大值為1 000 V AC或1 500 V DC。本部分適用于GB/T 18487.1中規(guī)定的充電模式2、充電模式3、充電模式4的供電設(shè)備。本部分適用于從現(xiàn)場儲(chǔ)能系統(tǒng)(如緩沖蓄電池組等)獲得能量的電動(dòng)汽車供電設(shè)備。本部分認(rèn)為無電子元件或開關(guān)(除手動(dòng)開關(guān)外)的電纜是無源的，符合發(fā)射和抗擾度要求，不需要測試。本部分不適用于任何車載供電設(shè)備和電動(dòng)汽車的供電系統(tǒng)的零部件和設(shè)備。本部分不適用于以無線充電(WPT)方式為電動(dòng)汽車供電或充電的供電設(shè)備。本部分不適用于無軌電車、鐵路車輛、工業(yè)車輛和主要用于非道路車輛的供電設(shè)備。

GB/T 26831.4-2017社區(qū)能源計(jì)量抄收系統(tǒng)規(guī)范 第4部分:儀表的無線抄讀

GB/T 26831的本部分規(guī)定了用于遠(yuǎn)程無線讀表系統(tǒng)的物理層和鏈路層的參數(shù)要求。本部分適用于使用免許可證的433 MHz~434 MHz無線民用頻段和470 MHz~510 MHz計(jì)量頻段的“短距設(shè)備”(SRD)，涵蓋便攜設(shè)備、可移動(dòng)設(shè)備和固定設(shè)備。由于有一個(gè)廣泛的定義，本部分可用于不同的應(yīng)用層。

JB/T 10451-2004多用戶靜止式交流有功電能表.特殊要求

本標(biāo)準(zhǔn)規(guī)定了多用戶靜止式交流有功電能表的分類、技術(shù)要求、試驗(yàn)方法、檢驗(yàn)規(guī)則、標(biāo)志、包裝及貯存。其測量部分的基本要求應(yīng)符合GB/T 17215標(biāo)準(zhǔn)的規(guī)定。　　本標(biāo)準(zhǔn)適用于固定安裝、參比和頻率為50Hz(或60Hz)能夠測量多個(gè)電能用戶有功電能的靜止式儀表，該表由包封在同一表殼內(nèi)的多個(gè)測量單元和計(jì)度器(register)組成。如果儀表表殼內(nèi)包封具有其他功能單元，如大需量指示器、電子費(fèi)率計(jì)度器、時(shí)間開關(guān)、數(shù)據(jù)通信接口等，則應(yīng)用與這些功能相關(guān)的標(biāo)準(zhǔn)。　　組合式電能表(每個(gè)計(jì)量單元結(jié)構(gòu)相對獨(dú)立，計(jì)量單元數(shù)可根據(jù)電能用戶數(shù)量改變，共用一個(gè)顯示單元的儀表)等類似產(chǎn)品可參照本標(biāo)準(zhǔn)。

ITU-R RAPPORT SM.2130 FRENCH-2008無線電臺的檢查

This Report presents an overview of Inspections Procedures in response to Question ITU-R 225/1 regarding inspection techniques and procedures. The Question relates to how administrations proceed in planning and conducting radio station inspections. The purpose of this Report is to provide general guidelines for planning and performing inspection activities on various types of radio stations. Inspection activities often include review and verification of both technical and administrative conditions assigned to a radio station or other spectrum user. Although the term “l(fā)icensed” is used throughout the document, this term can be considered here to include not only stations with licences issued by the regulatory authority, but also other authorized spectrum users (such as those operating with “l(fā)icence exempt” devices like low-power radios and RF devices operating under equipment standards approval). The primary focus of this report is to consider inspections that are conducted “on-site”, by visiting the transmitter location. Included in Annexes are some specific examples in certain services, toprovide examples of howthe general guidelines can be applied. This Report should be considered a general guidance document for inspections planning.
