  Abstract:This article describes the application of prepaid public energy meter in South Africa. Single-phase prepaid  public meters and three-phase prepaid public meters are new prepaid electric energy meters that integrate measurement and control. They support radio frequency recharge and remote recharge, and have multiple control modes such as payment control, time control, and vicious load control. It can be built-in 100A large-capacity magnetic latching relay to realize partial closing of the electric meter, and it can also provide passive dry contact output to control the external circuit breaker to realize the tripping function. It is widely used in the management of prepaid electricity consumption in commercial plazas, residential dormitories and college dormitories.

  1.項目概述(shù) Project overview:

  此(cǐ)公(gōng)司是南非(fēi)的充(chōng)電(diàn)樁公(gōng)司，該公(gōng)司想要采購(gòu)單相和三相(xiāng)的(dí)預(yù)付(fù)費電表(biǎo)用於(yú)測試，通過(guò)預付費電(diàn)表時間控(kòng)製(zhì)，付(fù)費控製(zhì)的功能，實現多人共(gòng)同(tóng)使用(yòng)充電(diàn)樁(zhuāng)充(chōng)電的目的(dí)。在了解了(liǎo)客(kè)戶(hù)的應(yīng)用場(cháng)景和(hé)需(xū)求(qiú)後，推薦了單相(xiāng)，三(sān)相(xiāng)的灌溉表及本(běn)地(dì)預付(fù)費充值(zhí)係統。

  This company is a charging pile company in South Africa. The company wants to purchase single-phase and three-phase prepaid meters for testing. Through the time control and payment control functions of prepaid meters, it can realize the purpose of multiple people using charging piles for charging. After understanding the customer's application scenarios and needs, single-phase and three-phase public meters and local prepaid recharge systems were recommended.

  2. 預付費灌溉(gài)表(biǎo)的(dí)優點

  Advantages of prepaid public energy meter

  預(yù)付費電(diàn)表(biǎo)先(xiān)付(fù)費後用電(diàn)與傳統(tǒng)後(hòu)付費電表(biǎo)相比，導軌(guǐ)式預付(fù)費灌溉(gài)表具有(yǒu)以(yǐ)下優點：

  1）導軌(guǐ)式(shì)安(ān)裝，無(wú)需(xū)在(zài)牆(qiáng)麵(miàn)上打(dǎ)孔，破壞(huài)建築(zhù)，隻需要(yào)將(jiāng)表(biǎo)卡在35mm導軌上即(jí)可，安裝方便快(kuài)捷(jié)且不會(huì)對安裝(zhuāng)地(dì)造成損壞(huài)；

  2）區別(bié)於傳統先計量再(zài)收費模式(shì)，實行先付(fù)費後(hòu)用(yòng)電的模式(shì)，方便(biàn)對用(yòng)戶(hù)的統一管(guǎn)理，節省(shěng)了抄(chāo)表(biǎo)及收(shōu)費(fèi)的(dí)時間和人(rén)工(gōng)成本，解決了收(shōu)費困難的(dí)問題(tí)；

  3）以(yǐ)卡(qiǎ)為介(jiè)質(zhì)，將(jiāng)電費通過刷(shuā)卡(qiǎ)形式充入電能(néng)表(biǎo)內(nèi)。內控型(xíng)電表，支持遠(yuǎn)程(chéng)充值，減少(shǎo)人力維護成(chéng)本，提高(gāo)用戶體驗。

  Compared with traditional post-paid energy meters, the guide rail type prepaid public meters have the following advantages:

  1) Rail-type installation, no need to punch holes on the wall and damage the building, just clip the watch on the 35mm rail, which is convenient and quick to install and will not cause damage to the installation site;

  2) Different from the traditional metering and then charging mode, it implements the mode of paying first and then using electricity, which facilitates the unified management of users, saves the time and labor cost of meter reading and charging, and solves the problem of charging difficulties;

  3) Using the card as the medium, charge the electricity bill into the electric energy meter by swiping the card. The internally controlled electric meter supports remote recharge, reduces manpower maintenance costs, and improves user experience.

  3. 產(chǎn)品(pǐn)選型(xíng)Product Selection

  4.應用Application

  此(cǐ)灌溉表原本是應用於本(běn)土的農業灌(guàn)溉，因客戶(hù)的應(yīng)用(yòng)場景及公共(gòng)使用的(dí)需(xū)求，經(jīng)項目(mù)評(píng)估(gū)可以用於電動車充(chōng)電樁的公(gōng)共(gòng)場所刷卡(qiǎ)充值。我們(mén)為使用者配(pèi)備一張(zhāng)RF 卡，通(tōng)過讀(dú)卡器(qì)及預付費(fèi)充(chōng)值係(xì)統，可以(yǐ)為使(shǐ)用(yòng)者購電(diàn)寫卡(qiǎ)以及(jí)回(huí)收(shōu)清(qīng)零(líng)，用戶有(yǒu)充電需(xū)求時(shí)，隻需(xū)在電表(biǎo)上刷一下即(jí)可開始充電，充(chōng)滿後再(zài)刷(shuā)一下(xià)則取(qǔ)回卡(qiǎ)中(zhōng)餘款(kuǎn)，使(shǐ)用方便(biàn)快(kuài)捷。

  This public energy meter was originally used for local agricultural irrigation. Due to the customer's application scenarios and public use needs, it can be used for recharging in public places of electric vehicle charging piles after project evaluation. We provide users with an RF card. Through the card reader and prepaid recharge system, users can purchase electricity, write cards, and reset them. When users need to charge, they only need to swipe the meter to start charging. , Swipe again after full charge to retrieve the balance in the card, which is convenient and quick to use.

  5 .結論Conclusion

  隨(suí)著(zhuó)環境(jìng)問題的(dí)突出(chū)，電動(dòng)汽車(chē)已(yǐ)經越來越(yuè)成為未來交通工(gōng)具的主(zhǔ)流(liú)，與之配(pèi)備的(dí)充(chōng)電(diàn)樁的需求(qiú)也(yě)越來越大，公共(gòng)電動(dòng)汽(qì)車充電樁通過(guò)預付費表控製啟停(tíng)在未來將(jiāng)為更多的使(shǐ)用者提供方(fāng)便快捷的(dí)服(fú)務(wù)。未來(lái)安科(kē)瑞(ruì)將提供更(gēng)加智(zhì)能化(huà)的預付(fù)費平台(tái)，更(gēng)方便於(yú)用戶(hù)的(dí)使用和(hé)統一的管理。

  With the emergence of environmental problems, electric vehicles have become the mainstream of future transportation, and the demand for charging piles equipped with them is also increasing. Public electric vehicle charging piles will be controlled by the prepaid meter to start and stop in the future. More users provide convenient and efficient services. In the future, Acrel will provide a more intelligent prepaid platform, which is more convenient for users to use and unified management.
