AO810V2模拟量输入模块
参数“DefDirMode”决定了最后的响应确定的时间。它可以设置为任意方向（在跳闸方向）或非方向（见图3.5.31.8）。
注：即使使用过电流，仍有一个确定的区域
启动器（OC），但仅与参数延迟有关（Def）和“DefDirMode”。

参数“I O/C”确定拾取级别，可以是在0.1英寸到10英寸之间的步骤中选择。关联
通过以下方式将时间延迟设置为0.1秒，介于0和10秒之间：参数“延迟O/C”。过电流装置的拾取信号也用于存根保护。如果该功能用于此目的，i、 e.二进制i/P“隔离开关打开”处于逻辑“1”，跳闸时间为固定在25ms。3.5.31.6.V.t.监督（见第4.8.3节。）
设置v.t.监控功能的参数位于子菜单“v.t.SUPERVISON”中。可以使用“VTSupMode”选择四种不同的操作模式之一。
这个函数处理零序和负序分量
它们要么单独使用（“零序列”和“负序列”），要么组合（“零*NegSeq”和“Spec”）。四个拾取值是参数的设置“U0min VTSup”、“U2min Vtsop”、“I0min VTSup”和“I2min VTSup”。
它们可以在0.01的步骤中设置在0和2 UN（或IN）之间
电压的基本设置为0.2 UN，电压为0.07 IN
现在的只有“NegSeq”或“Spec”选项不接地系统。
运行时，通常需要v.t.监督功能要立即阻止距离保护功能（请参阅第4.8.5.2节）。但是，为阻止
通过设置参数，延迟12秒后的距离函数“VTSupBlkDel”。该参数通常在以下情况下设置：
仅使用过电流启动器。如果v.t.监控功能保持启动的时间超过12秒，它仅在延迟（1s）后复位。错误是否会导致零序或负序电流分量，立即复位。
参数“VTSupDebDel”（解块）启用重置无论电流如何，延迟将持续启用。
The parameter ‘DefDirMode’ determines the response at the end
of the definitive time. It can be set to be either directional (in
tripping direction) or non-directional (see Fig. 3.5.31.8).
Note:
There is still a definitive zone even using the overcurrent
starter (OC), but only with respect to the parameters ‘Delay
(Def)’ and ‘DefDirMode’.
3.5.31.5. Back-up overcurrent unit
(O/C Back-up Protection)
(see Section 4.8.4.)
The settings for the back-up overcurrent unit are made via the
sub-menu ‘O/C BACK-UP PROTECTION’. The setting of the
parameter ‘I O/C’ determines the pick-up level, which can be
chosen in steps of 0.1 IN between 0 and 10 IN. The associated
time delay is set in steps of 0.1 s between 0 and 10 s by means
of the parameter ‘Delay O/C’.The pick-up signal of the overcurrent unit is also used by the
STUB protection. If the function is being used for this purpose,
i.e. the binary I/P ‘Isol open’ is at logical ‘1’, the tripping time is
fixed at 25 ms.
3.5.31.6. V.t. supervision
(see Section 4.8.3.)
The parameters for setting the v.t. supervision function are located in the sub-menu ‘V.T. SUPERVISON’. One of four different operating modes can be chosen using ‘VTSupMode’. The
function processes zero and negative-sequence components,
which are either used on their own ('ZeroSeq’ and ‘NegSeq') or
combined ('Zero*NegSeq’ and ‘Spec').The four pick-up values are the settings of the parameters
‘U0min VTSup’, ‘U2min VTSup’, ‘I0min VTSup’ and ‘I2min VTSup’.
They can be set between 0 and 2 UN (or IN) in steps of 0.01. The
basic settings are 0.2 UN for the voltage and 0.07 IN for the
current.
Only the ‘NegSeq’ or ‘Spec’ options are available in ungrounded
systems.
Upon operating, the v.t. supervision function is normally required
to immediately block the distance protection function (see
Section 4.8.5.2.). Provision is made, however, for blocking the
distance function after a delay of 12 s by setting the parameter
‘VTSupBlkDel’. This parameter is normally set in cases where
only the overcurrent starters are in use.If the v.t. supervision function remains picked up for longer than
12 s, it resets only after a delay (1 s). Should a fault give rise to
zero or negative-sequence current components, it resets immediately.
The parameter ‘VTSupDebDel’ (deblocking) enables the reset
delay to be continuously enabled regardless of current.
