电压方向继电器是当断开的断路器或接触器的两端电压超过给定值并与给定方向一致时动作的继电器。

92 Voltage and power directional relay is a relay that permits or causes the connection of two circuits when the voltage difference between them exceeds a given value in a predetermined direction and causes these two circuits to be disconnected from each other when the power flowing between them exceeds a given value in the opposite direction.

电压和功率方向继电器是当两个回路之间的电压差值超过给定值并与预定方向一致时，允许或使这两个回路并列，而当两个回路间功率潮流在相反方向超过给定值时，则使这两个回路彼此解列的继电器。

93 Field-changing contactor functions to increase or decrease, in one step, the value of field excitation on a

machine.

磁场变换接触器的功能是对一台发电机的励磁值进行按级升降操作。

94 Tripping or trip-free relay functions to trip a circuit breaker, contactor, or equipment, or to permit immediate tripping by other devices; or to prevent immediate reclosing of a circuit interrupter if it should open automatically, even though its closing circuit is maintained closed.

跳闸或自动跳闸继电器其功能是使断路器、接触器或设备进行跳闸，或允许由其它元件立即进行跳闸，并防止断路器跳闸后立即重合闸，即使断路器的合闸回路仍保持闭合状态，它也应自动地断开。

95,96,97,98,99 Used only for specific applications on individual installations where none of the assigned numbered functions from 1 to 94 is suitable.

为那些已指定的功能编号1～94所不适用的各个单独安装的设备所专用。

Supervisory control and indication. A similar series of numbers, prefixed by the letters RE (for “remote”) shall be used for the interposing relays. performing functions that are controlled directly from the supervisory system. Typical examples of such device functions are: RE1, RE5 and RE94.

监控与指示：通过增加前缀字母RE形成的类似的一系列数字，应用于直接由监控系统控制的继电器。像这样装置功能的典型例子如：RE1，RE5和RE94。Note: The user of the “RE” prefix for this purpose in place of the former 200 series of numbers now makes it possible to obtain increased flexibility of the device function numbering system. For example, in pipeline pump stations, the numbers 1 through 99 are applied to device functions that are associated with the over-all station operation. A similar series of numbers, starting with 101 instead of 1, are used for those device functions that are associated with unit 1; a similar series starting with 201 for device functions that are associated with unit 2; and so on, for each unit in these installations.

备注(说明)：以加前缀RE目的来取代以前200系列代码的做法，使得装置功能编号系统更具灵活性。例如：在管道输送泵站，以1到99应用的装置就可以用于所有相关功能操作。一序列数字，开始以101取代1，用于表达那些与单元1有关的装置功能，一序列以起始于201数字用于表达与单元2有关的装置功能，以此类推，能够对应于每套这些设施。

Devices performing more than one function多功能的装置

If one device performs two relatively important functions in an equipment so that it is desirable to identify both of these functions, this may be done by using a double function number and name such as: 50/51 Instantaneous and Time Over-current relay.

如果一个设备中具有2个相对重要的功能，所以它便于识别这些功能，可以用双功能数字命名：如50/51表示瞬间过流继电器。

Suffix numbers 后缀数字

If two or more devices with the same function number and suffix letter (if used) are present in the same equipment, they may be distinguished by numbered suffixes as for example, 52X-1, 52X-2 and 52X-3, when necessary.

如果有同样功能的2以上的装置，以后缀字母表达该设备，如有必要时，可以用数字后缀来区别，例如：52X-1, 52X-2 and 52X-3

Suffix letters 后缀字母

Suffix letters are used with device function numbers for various purposes. In order to pre-vent possible conflict each suffix letter should have only one meaning in an individual equipment. All other words should use the abbreviations as contained in American Standard Z32.13-1950, or latest revision thereof, or should use some other distinctive abbreviation, or be written out in full each time they are used. The meaning of each single suffix letter, or combination of letters, should be clearly designated in the legend on the drawings or publications applying to the equipment. In cases where the same suffix (consisting of one letter or a combination of letters) has different meanings in the same equipment, depending upon the device function number with which is used, then the complete device function number with which it is used, the complete device function number with its suffix letter or letters and its corresponding function name should be listed in the legend in each case, as follows: 90V, Voltage regulator.

后缀字母配合装置功能代号，用于多种用途。为了防止可能的冲突，每个后缀字母对于一个独立设备必须仅能表达一种含义。所有其他词语用美国标准Z32.13-1950中的缩写，或是其最新修订版本，或是用一些其他有区别的缩写，或是每次引用时用其全拼。每个单独后缀字母或组合字母，必须在设备资料中清楚地指明。如果一台设备中有相同的后缀字母(包含单个字母或组合字母)有不同的含义时，取决于其应用的设备功能代号；当完整装置功能代号应用时，该功能代号附带后缀字母，必须在每种应用图例中列出，如90V,电压调节器。

Lower case (small) suffix letters are used in practically all instances on electrical diagrams for the auxiliary, position, and limit switches. Capital letters are generally used for all other suffix letters. The letters should generally form part of the device function designation, are usually written directly after the device function number, as for example, 52CS, 71W, or 49D. When it is necessary to use two types of suffix letters. in connection with one function number, it is often desirable for clarity to separate them by a slanted line or dash, as for example, 20D/CS or 20D-CS

小写后缀字母几乎应用于所有如电气辅助，位置，限位开关等图纸实例中。大写字母通常应用于其它后缀字母。这些字母作为通常设备功能标识的一部分，直接写在功能代号后面，例如：52CS,71W,或49D。当它有必要使用2中后缀类型连接于一个功能代号时，通常方便阐明，用斜杠线或短破折号分隔它们，如20D/CS或20D-CS。

The suffix letters which denote parts of the main device, and those which cannot or need not form part of the device function designation, are generally written

directly below the device function number on drawings, as for example, 52

CC or

43

A.

用于表达主设备部件的后缀字母，以及那些不能或不需要作为装置功能标识的一部分，在图纸资料中通常直接写在功能代号的下面。例如52

CC or 43 A。
