OKUMA BL4-D100A伺服驱动

产品详细资料
电流互感器输入745有八个或十一个交流电流输入通道，每个通道都有一个隔离变压器和一个自动短路机制，当继电器从外壳中取出时，该机制会起作用。电流输入上没有内部接地连接。可以使用初级电流为1至50000A的电流互感器。SR-745继电器具有两个或三个变压器绕组的输入（在订购时指定）以及两个接地电流输入G1/2和G2/3。有关详细信息，请参阅下面的接线图。在选择变压器类型时，接地输入在以下条件下与一个或另一个绕组相关联：1。接地输入设置将显示在与接地输入相关的变压器类型选择的绕组配置中。2.当选择2绕组变压器时，两个变压器上的接地输入都被启用，并且被预先分配。G1/2分配给绕组1，G2/3分配给绕组2。3.当选择三绕组变压器时，两个接地输入都被启用，并通过以下规则与绕组相关联（见表3-2）：•50G功能在所有连接情况下都被启用（即：delta和wye）。•在三绕组变压器的情况下，为用户提供了灵活性，因此用户可以将G1/2和G2/3接地输入分配给三个可用绕组中的任意两个。4.继电器内置的坚固性不允许用户将接地输入分配给多个绕组。在EnerVista 745软件中，一个标志用文本通知用户：“已为另一个绕组选择接地CT输入'G#/#'”。在继电器固件上，显示“Input Function is Already Assigned”（输入功能已分配）文本。
Current Transformer Inputs The 745 has eight or eleven channels for AC current inputs, each with an isolating transformer and an automatic shorting mechanism that acts when the relay is withdrawn from its case. There are no internal ground connections on the current inputs. Current transformers with 1 to 50000 A primaries may be used. The SR-745 Relay has inputs for either two or three transformer windings (specified at the time of ordering) and for two ground current inputs, G1/2 and G2/3. Refer to the wiring diagrams below for details. Upon transformer type selection, the ground inputs are associated to one or another winding under the following conditions: 1. The ground input settings will be shown in the winding configuration for the transformer type selections associated with a ground input. 2. When a 2-winding transformer is selected, ground inputs are enabled, on both, and are pre-assigned. G1/2 is assigned to winding 1, and G2/3 is assigned to winding 2. 3. When a 3-winding transformer is selected, both ground inputs are enabled, and are associated with the windings via the following rules (see table 3-2): • The 50G function is enabled for all connection scenarios (ie: delta and wye). • Flexibility is provided to the user in the case of a 3-winding transformer, so the user can assign G1/2 and G2/3 Ground inputs to any two of the three available windings. 4. Robustness, built into the relay, will not allow the user to assign a ground input to more than one winding. In the EnerVista 745 software, a flag informs the user with the text: "Ground CT Input ’G#/#’ has already been selected for another winding". On the relay firmware, "Input Function is Already Assigned" text is displayed.
