辅助电源通过上的开关关闭
辅助直流电源装置分别为216NG61。216NG62或216NG63。
在这方面必须注意以下几点：每个电子设备机架都配有自己的辅助电源装置。
一个或最多两个冗余216NG6.辅助d、 c.供应装置可安装在设备机架中。
如果安装了两个冗余辅助直流电源单元，必须关闭两个装置。（另见第2.2节。）
对保护进行的任何工作，如内部调整、插入焊接跳线、接线、连接等，可能只能由具有适当资质的人员执行。除这些说明外，所有适用的地方法规在安装、接线和调试保护装置时，必须严格遵守管理工作和安全。电子装置或软件的修改和维修用户可以不执行更改。不承担任何责任如果保护设备受到不当干扰或篡改，则任何保修均无效。有缺陷的机组必须返回ABB进行维修（另见第7节）
完整系统
再。216保护系统包括至少一个电子216MB62型设备机架，插入电子模块（插件单元）和多个I/O单元，这些单元实际上是与主设备的接口。保护系统是：可提供隔间型或紧凑型。
图12.1显示了216MB61设备机架的示例安装在保护柜的铰接框架中。电子模块设计为插入式单元从前面。B448C并行总线提供通信在电子单元之间，安装在机架后部。
位于后部的还有用于将标准电缆连接到I/O单元和用于连接打印机的连接器。输入变压器、辅助继电器I/O和跳闸继电器单元安装在保护装置后面板的内侧隔间（见图12.2.）。
安装的电子装置的数量和类型及其位置在机架中，机架的数量以及数量和排列输入/输出单元的数量因工厂而异。请参阅相应的一组图表，以执行再。216用于特定工厂的系统。REG 216保护的紧凑版本也可用，
基本上是一个标准化的设备机架（参见第节2.3.). 紧凑型可以安装在开放式框架或与其他设备一起安装在隔间内。2.2.隔间版本2.2.1.操作原理图2.1说明了个人的基本工作原理
构成完整保护的单元和模块系统
The auxiliary supply is switched off by means of a switch on the
auxiliary d.c. supply units 216NG61, resp. 216NG62 or 216NG63.
The following must be noted in this respect:
Every electronic equipment rack is equipped with its own
auxiliary power supply unit.
Either one or a maximum of two redundant 216NG6. auxiliary
d.c. supply units can be installed in an equipment rack.
Where two redundant auxiliary d.c. supply units are fitted,
both units must be switched off.
(See also Section 2.2.)
Any work carried out on the protection such as internal adjustments, inserting soldered jumpers, wiring, connections etc., may
only be performed by suitably qualified personnel.
In addition to these instructions, all applicable local regulations
governing work and safety must be strictly observed when installing, wiring and commissioning the protection.
Modifications and repairs to the electronic units or software
changes may not be performed by the user. No liability will be
accepted and any warranty becomes invalid in the case of improper interference or tampering with the protection equipment.
Defective units must be returned to ABB for repair (see also
Section 7.)Complete system
An RE. 216 protection system comprises at least an electronic
equipment rack Type 216MB62 with the electronic modules inserted (plug-in units) and a number of I/O units, which are in effect the interface with the primary plant. The protection system is
available as a cubicle version or as a compact version.
Figure 12.1 shows an example of a 216MB61 equipment rack
installed in the hinged frame of a protection cubicle. The electronic modules are designed as plug-in units, which are inserted
from the front. The B448C parallel bus provides communication
between the electronic units and is fitted to the rear of the rack.
Also situated at the rear are the connectors for the standard cables to the I/O units and for connecting a printer.
The input transformer, auxiliary relay I/O and tripping relay units
are mounted on the inside of the rear panel of the protection
cubicle (see Figure 12.2.).
The number and type of electronic units installed, their locations
in a rack, the number of racks and the number and arrangement
of I/O units varies from plant to plant.
Refer to the corresponding set of diagrams for the execution of
an RE. 216 system for a particular plant.
A compact version of the REG 216 protection is also available,
which is basically a standardised equipment rack (see Section
2.3.). The compact version can be mounted either in an open
frame or in a cubicle with other equipment.

Fig. 2.1 illustrates the basic operating principle of the individual
units and modules, which make up a complete protection
system.
