Application of Acrel Public Energy Meter in South Africa

摘要：本文介绍了预付费灌溉表表在南非的应用。单相预付费灌溉表和三相预付费灌溉表是集计量与控制与一身的新型预付费电能表，支持射频充值和远程充值，具有付费控制、时间控制、恶性负载控制等多种控制模式。可内置100A大容量磁保持继电器实现电表内部分合闸，也可提供无源干接点输出控制外部断路器实现跳闸功能。广泛应用于商业广场、居民宿舍以及高校宿舍的预付费用电管理。

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.项目概述 Project overview:

此公司是南非的充电桩公司，该公司想要采购单相和三相的预付费电表用于测试，通过预付费电表时间控制、付费控制的功能，实现多人共同使用充电桩充电的目的。在了解了客户的应用场景和需求后，推荐了单相、三相的灌溉表及本地预付费充值系统。

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. 预付费灌溉表的优点

Advantages of prepaid public energy meter

预付费电表先付费后用电与传统后付费电表相比，导轨式预付费灌溉表具有以下优点：

1）导轨式安装，*在墙面上打孔，破坏建筑，只需要将表卡在35mm导轨上即可，安装方便快捷且不会对安装地造成损坏；

2）区别于传统先计量再收费模式，实行先付费后用电的模式，方便对用户的统一管理，节省了抄表及收费的时间和人工成本，解决了收费困难的问题；

3）以卡为介质，将电费通过刷卡形式充入电能表内。内控型电表，支持远程充值，减少人力维护成本，提高用户体验。

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.

4.应用Application

此灌溉表原本是应用于本土的农业灌溉，因客户的应用场景及公共使用的需求，经项目评估可以用于电动车充电桩的公共场所刷卡充值。我们为使用者配备一张RF 卡，通过读卡器及预付费充值系统，可以为使用者购电写卡以及回收清零，用户有充电需求时，只需在电表上刷一下即可开始充电，充满后再刷一下则取回卡中余款，使用方便快捷。

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 .结论Conclusion

随着环境问题的**，电动汽车已经越来越成为未来交通工具的主流，与之配备的充电桩的需求也越来越大，公共电动汽车充电桩通过预付费表控制启停在未来将为更多的使用者提供方便快捷的服务。未来安科瑞将提供更加智能化的预付费平台，更方便于用户的使用和统一的管理。

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.
