11.8 Class 8: Delivery function交付功能

        Capability of delivering metered electrical energy to the customer’s load circuit and to regulate the quantity and/or availability in accordance with regulating control instructions from the Accounting function and any constraining rules.
        交付电能给用户负荷线路，并根据来自于帐户功能和其他限制制度的调节控制指令，控制数量或可用性。
        Regulates the amount of electrical energy delivered to the customer’s load circuit in accordance with the available credit in the Accounting function.
        根据帐户功能中可用的CREDIT，控制交付到用户负载线路的电量的数量。
        Receives a delivery configuration profile from the Contract function.
        从合同功能中得到交付配置界面。
        Receives metered electrical energy from the Metering function.
        从表计功能中得到表计中的电量。
        Provides a load interface for connection to the customer’s load circuit.
        提供负载接口，用于连接到用户的负载线路。
        Delivers the electrical energy to the customer’s load circuit.
        交付电量到用户的负载线路。
        Optionally monitors the attribute values of other functions and may interrupt the supply in response to detected changes in accordance with the delivery configuration profile attributes.
        监视其它功能的属性值，根据检测到交付的属性的变化可以中断电量供应。
        An example of attributes for a delivery configuration profile is:
        以下是交付属性的举例
        service type (electricity, water, gas, etc.);
        通用性（电、水、气）
        constraining rules placed on interruption and restoration of the supply to the customer’s load circuit; (Examples are: non-interrupt times, non-supply times, life-line supply on expiry of credit, power limiting if below certain average consumption level);
        对于用户负载线路，供电的中断和恢复有强制的规则，例如非中断次数、非供电次数、CREDIT期满后的延期、低于某个平均消耗水平时的功率限制。
        detection control parameters (Examples are: overvoltage, undervoltage, voltage dips,voltage interruptions, power limits, voltage reverse polarity, reverse energy, phase unbalance, expiry of available credit, replenishment of available credit);
        检测控制参数，例如过压、低压、电压DIP、电压中断、功率限制、电压反向、电能反向、相
位不平衡、可用CREDIT到期、可用CREDIT补充。
        control parameters for automatic interruption of supply to the load;
        自动切断供电的控制参数
        control parameters for automatic restoration of supply to the load;
        自动恢复供电的控制参数
        control parameters for manual restoration of supply to the load;
        手动恢复供电的控制参数
        control parameters for safety protection (overcurrent limit, earth-leakage limit).
        安全保护的控制参数
        NOTE 1 This function is not to be confused with the connection of the customer installation to the distribution network, which is a different process (see 10.6, Connection_Authorization process class 6). See also Distribution function.
        注释1：该功能不要和用户装置到配电网络连接的功能相混淆，是不同的过程（见10.6连接授权过程），也可参见配电功能。
        NOTE 2 Delivery equipment is typically part of the customer installation and the load interface terminal set is legally and technically the Point_Of_Delivery.
        注释2：交付设备是用户设备的典型部分，负载接口端子是合理的，技术可行的交付点。
        NOTE 3 Some payment meters have Delivery functions that offer safety protection features like overcurrent,earth-leakage and mains isolation. These functions are the subject of other relevant specifications.
        注释3：一些有交付功能的付费电能表提供了安全保护功能，如过流、通地漏泄和干线绝缘。这些功能在其他相关规范中有所阐述。
        NOTE 4 The load interface terminals may follow various standards like DIN, BS or other national standards.
        注释4：负载接口端子有不同的标准，如DIN、BS、或其他标准
        NOTE 5 In some implementations, the payment meter may have an integrated power socket outlet, in which case there is no additional distribution board or house wiring installed at the premises.
        注释5：在一些设备中，付费电表有电力插座接口，没有附加的配电板或配线
        NOTE 6 A load switch typically performs the function of supply interruption and restoration to
the load.
        注释6：负载开关实现断电和恢复供电的功能
        NOTE 7 Some payment meters have additional switching elements that perform functions other than that of the load switch. These switching elements may be physically separate devices or may actually share the same elements of the load switch, in which case the same load switch performs several functions.
        注释7：一些表计有附加的开关单元实现负载开关以外的功能。这些开关单元可以是物理分离的设备，也可以与负载开关一体的设备，这样，同一个开关就可以实现多种功能。
        NOTE 8 Manual restoration requires the presence and intervention of the user. Examples are:manual insertion of a token carrier, entering a code, pushing a button or operating a lever on the user interface.
        注释8：手动恢复需要用户参与。例如手动插入TOKEN载体、输入密码、按键或在用户接口上操作。
        NOTE 9 Automatic restoration does not require the presence or intervention of the user. For example: recovery from an undervoltage condition or from a voltage interruption.
        注释9：自动恢复不需要用户参与。例如从低电压条件或从电压中断中恢复
        NOTE 10 In the case of a single-part payment meter, the Metering function and the Delivery function would be contained in the same physical unit. These two functions may alternatively be physically separated, in which case an interface exists between them. Such an instance would constitute a multi-part payment meter installation.
        注释10：对于单边付费的表计表计功能和交付功能应该包括在同一个物理单元中。这两个功能可以是物理分离的这时两者之间存在接口。该例构造了一个多部分的表计设备。
