ABB HS840 3BDH000307R0101 变频器

产品详情资料

ABB HS840 3BDH000307R0101 装置的辅助继电器K1…K16。辅助继电器触点可能是自由的，并连接到端子，以连接到外部信号和跳闸电路。连接到保护装置的外部输入信号使216GE61 I/P继电器单元中的辅助继电器K1…K16通电。K1…K16的潜在自由触点将外部信号传输至216DB61单元，然后传输至B448C总线。通过216VC62a处理单元中软件的适当配置，可以将外部信号分配给各种保护功能，例如与跳闸信号的逻辑组合（联锁和闭锁）或激励跳闸通道1…8。跳闸电路1…8可通过216GA62的二极管矩阵（跳闸逻辑）由216GE61的全部或部分I/P通道1…10（K1…K10）直接通电（见第2.6节）。还规定了216GE61的一些通道9…16（K9…K16）用于监测外部跳闸电路1…8，而不是用于连接外部输入。这是一个选项，必须在设计保护时指定，以使相应的接线包括在内。为了给电子单元供电，保护装置必须连接到外部辅助直流电源（厂用蓄电池）。辅助直流电源装置216NG61、216NG62或216NG63（DC/DC转换器）将电站电池电压降至24 V，并在输入和输出电压之间提供电气绝缘。24V电源通过B448C并行总线分配给插入保护设备机架的装置。216NG61、216NG62或216NG63电源装置也为I/O装置上的电子电路供电。216MB66设备机架只能配备一个或两个冗余216NG61、216NG62或216NG63辅助直流电源RE。216 1MDU02005-EN/2/Rev.G ABB Switzerland Ltd 2-7机组。冗余单元可以连接到同一个或两个不同的站电池。所有软件配置，即保护功能的选择和设置以及输入和输出信号的分配，均通过216VC62a处理单元上的RS-423串行接口执行。相应的连接器是装置正面的25针插座X2，与个人计算机相连。2.2.2.216MB66型设备机架的布局图2.2显示了设备机架中电子单元的布置示例。设备机架细分为21个分区（T）。分区1-3和19-21通常用于辅助直流电源装置216NG61、216NG62或216NG63。原则上，电子装置可以位于其余分区4-18中的任何一个，前提是相应安装了系统电缆连接。然而，出于标准化的原因，各种类型的装置始终位于设备机架的相同位置。The digitised measured variables derived from the primary system quantities are continuously compared by the processing unit 216VC62a with the pick-up settings of the protection functions. If a protection function picks up, the corresponding signal or tripping command is transmitted via the B448C bus to the 216AB61 O/P unit resp. to the 216DB61 I/O unit. The allocation of the signals and tripping commands at the O/P’s of the protection functions to the various channels of the 216AB61 output unit or of the 216DB61 I/P signal and tripping unit is also determined by the software installed in the 216VC62a processor unit. The output signals from the 216AB61 unit (signalling channels) and 216DB61 unit (trip channels) control the auxiliary relays K1...K16 of the 216GA61 O/P relay unit or 216GA62 tripping relay unit. The auxiliary relays' contacts are potentially-free and wired to terminals for connection to external signalling and tripping circuits. The external input signals connected to the protection energise the auxiliary relays K1...K16 in the 216GE61 I/P relay unit. The potentially-free contacts of K1...K16 transmit the external signals to the 216DB61 unit and thence to the B448C bus. By appropriate configuration of the software in the 216VC62a processing unit, external signals can be assigned to the various protection functions, e.g. for logical combination (interlocking and blocking) with trip signals or for exciting the tripping channels 1...8. Tripping circuits 1...8 can be directly energised by all or just some of the I/P channels 1...10 (K1...K10) of 216GE61 via the diode matrix (tripping logic) of 216GA62 (see Section 2.6.). Provision is also made for some of the channels 9...16 (K9...K16) of 216GE61 to be used for supervising the external tripping circuits 1...8 instead of for the connection of external inputs. This is an option, which must be specified in the order to enable the corresponding wiring to be included when engineering the protection. In order to supply the electronic units with power the protection must be connected to an external auxiliary d.c. supply (station battery). The auxiliary d.c. supply unit 216NG61, 216NG62 or 216NG63 (DC/DC converters) steps the station battery voltage down to 24 V and provides electrical insulation between input and output voltages. The 24 V supply is distributed to the units inserted in the protection equipment rack via the B448C parallel bus. The 216NG61, 216NG62 or 216NG63 power supply unit also supplies the electronic circuits on the I/O units. A 216MB66 equipment rack can be equipped with just one or with two redundant 216NG61, 216NG62 or 216NG63 auxiliary d.c. supply RE. 216 1MDU02005-EN / 2 / Rev. G ABB Switzerl
