13.7.3 Sub-classification of the Metering functions计量功能的子分级

The Metering function primarily deals with the measurement of the quantity of delivered electrical energy to the consumer. These measurements are made available for use by other functions in the payment meter.

        计量功能主要是计量传输到用户的电量。这些计量值可以被付费电表的其它功能所利用。

The main attributes of Metering functions are given in Table 19 below.
        表19给出了计量功能的主要属性。

13.7.4 Sub-classification of the Delivery functions交付功能的子分级

The Delivery function primarily deals with the functions related to the delivery of electrical energy to the consumer’s load circuit. It also monitors the status of the attributes of other functions, in response to which it interrupts or restores the supply to the consumer’s load.
        交付功能首先处理和用户负荷线路的电能交付相关的功能。还监视其他功能属性的状态，包括供电部门对用户负荷的中断和恢复。

Table 20 – Sub-classification of the Delivery functions 交付功能的子分级

Load_Interface 负荷接口
Delivery functions that enable the consumer’s load circuit to be connected to the payment meter. Examples are: Directly wired connection to load-side terminals of the payment meter, an integral socket outlet built into the payment meter into which the consumer directly plugs his load, connection to the load-side terminals of an external load switch (single- or poly-phase) controlled by a low-current relay in the payment meter.
        交付功能可以实现用户负荷线路与预付费表之间的连接。例如：直接连接到付费表计的负荷端，用户直接将负荷插到表计的输出插座上，一个外接负荷开关（单或多相）连接到负荷端，负荷开关被预付费表中的继电器控制。
Detection 检测
Delivery functions that monitor and detect changes in the state of theattributes of other functions, in response to which it will interrupt or restore the load.
        监视和检测其他功能的属性状态的变化，从而中断或恢复负荷。
For example: detection of: overvoltage, undervoltage, voltage dip s, voltage interruptions, power limit, voltage reverse polarity, reverse energy, phase unbalance, expiry of available credit, replenishment of available credit
        检测内容：例如过压、低压、电压中断、功率极限、电压逆相、相位不平衡、信用到期、信用补充。
Load_Interruption 负荷中断
Delivery functions that deal with the interruption of the supply to the load in accordance with a
defined set of rules that are linked to the detection functions.
        根据检测功能定义的规约，交付功能处理供电部门到负荷的中断。
For example: Interrupt on detection of undervoltage, interrupt on detection of available credit expiry and interrupt on detection of power limit.
        例如低压检测中断、信用检测中断、功率极限检测中断。
Load_Restoration 负荷恢复
Delivery functions that deal with the restoration of the supply to the load in accordance with a
defined set of rules that are linked to the detection functions.
        根据检测功能定义的规约交付处理供电部门到负荷的恢复。
A particular load switch could possibly have both automatic and manual restoration functions, where automatic restoration is programmed to apply only to selective Detection functions and others to manual restoration. For example: Automatic restoration when undervoltage conditions return to normal, but manual restoration after interruption due to power limit detection.
        专门的负荷开关有自动和手动恢复功能，在某些条件使用自动恢复，其他情况下使用手动恢复。例如在低压为正常时自动恢复，而由于功率极限中断，需手动恢复。
These functions are further sub-classified into Automatic_Restoration and Manual_Restoration functions
        这些功能对于自动恢复和手动恢复功能时更深一层的分级。
Automatic_Restoration 自动恢复
Delivery functions that deal with the automatic restoration of the supply to the load, where the presence and intervention of a user is not required.
        不需要用户的干预，交付功能处理供电部门到负荷的自动恢复。
Example: After recovery from an undervoltage condition.
        例如从低压条件下恢复。
Manual_Restoration 手动恢复
Delivery functions that deal with the manual restoration of the supply to the load, where the presence and intervention of a user is required.
        需要用户干预，交付功能处理供电部门到负荷的手动恢复。
Examples are: Replenishing available credit by means of a physical token carrier, entering of a code on the user interface, pushing of a key or a button or operating a lever on the user interface
        例如：通过物理TOKEN载体，进入用户界面代码，按键或钮或用户界面操作，来补充信用。
Safety_Protection 安全保护
These functions are outside of the scope of this technical report.
These functions are further sub-classified into Over_Current, Earth_Leakage and Mains_Isolation functions.
        这些功能超出了技术报告的范围。
        这些功能是到过流、通地漏泄、干线绝缘功能的更深一步的子分级。
Over_Current 过流
These functions are outside of the scope of this technical report
        该功能超出了技术报告的范围
Earth_Leakage These functions are outside of the scope of this technical report,Mains_Isolation These functions are outside of the scope of this technical report.
        通地漏泄、干线绝缘超出了技术报告的范围。
NOTE 1 A payment meter may implement any one or more combinations of these functions.
        预付费表计可以是任意一个或多个功能相结合的设备。
NOTE 2 The Safety_Protection functions are mentioned here for completeness, but are excluded from the scope of this technical report. These functions are the subjects of other relevant specifications.
        这里提到的安全保护功能不在技术报告的范围内。这些功能与其他相关规范有关。

The main attributes of the Delivery functions are given in Table 21 below
        表 21 中给出了交付功能的主要属性
Table 21 – Main attributes of the Delivery functions 交付功能的主要属性

Service_ Type 服务类型
Determines which service type is being delivered (electricity, water, gas,heat, time)
        被交付的电、水、气、热、时间等决定服务类型
Constraints 限制
A set of rules that place constraints on the behaviour of Delivery functions.
        一套规则限制着交付功能的使用。
Constraints are either time-based or consumption-based.
        限制源于时间或消耗。
Examples are:At certain times of the day or night the load switch may not interrupt the load during winter season, or over weekends, or on public holidays.
        例如：在冬天、周末或其他公共假期期间，白天或夜晚的某一时间，负荷开关不会断开负荷。
Conversely the supplier may contract with the customer that the supply will be interrupted during certain times of the day irrespective of whether there is available credit.
        供电部门与用户签定合同，无论是否信用可用，供电部门白天的某个时刻进行断电。
Upon expiry of credit, then limit the load current to a 5 A lifeline supply, but only if the monthly average consumption is below 200 kWh, based on the average for the previous 6 months. In this case, the load switch may interrupt above 5 A, and automatically restore below 5 A load current
        信用期满，限制负荷电流为 5A，但如果每月平均耗电低于 200 kWh，基于前 6 个月的平均值。在这种情况下，负荷开关可能在高于 5A 时断电，负荷电流低于 5A 时自动恢复。
