輔助直流電源裝置分別為216NG61。216NG62或216NG63。
在這方面必須注意以下幾點(diǎn)：每個(gè)電子設備機架都配有自己的輔助電源裝置。
一個(gè)或最多兩個(gè)冗余216NG6.輔助d、 c.供應裝置可安裝在設備機架中。
如果安裝了兩個(gè)冗余輔助直流電源單元，必須關(guān)閉兩個(gè)裝置。（另見(jiàn)第2.2節。）
對保護進(jìn)行的任何工作，如內部調整、插入焊接跳線(xiàn)、接線(xiàn)、連接等，可能只能由具有適當資質(zhì)的人員執行。除這些說(shuō)明外，所有適用的地方法規在安裝、接線(xiàn)和調試保護裝置時(shí)，必須嚴格遵守管理工作和安全。電子裝置或軟件的修改和維修用戶(hù)可以不執行更改。不承擔任何責任如果保護設備受到不當干擾或篡改，則任何保修均無(wú)效。有缺陷的機組必須返回ABB進(jìn)行維修（另見(jiàn)第7節）
完整系統
再。216保護系統包括至少一個(gè)電子216MB62型設備機架，插入電子模塊（插件單元）和多個(gè)I/O單元，這些單元實(shí)際上是與主設備的接口。保護系統是：可提供隔間型或緊湊型。
圖12.1顯示了216MB61設備機架的示例安裝在保護柜的鉸接框架中。電子模塊設計為插入式單元從前面。B448C并行總線(xiàn)提供通信在電子單元之間，安裝在機架后部。
位于后部的還有用于將標準電纜連接到I/O單元和用于連接打印機的連接器。輸入變壓器、輔助繼電器I/O和跳閘繼電器單元安裝在保護裝置后面板的內側隔間（見(jiàn)圖12.2.）。
安裝的電子裝置的數量和類(lèi)型及其位置在機架中，機架的數量以及數量和排列輸入/輸出單元的數量因工廠(chǎng)而異。請參閱相應的一組圖表，以執行再。216用于特定工廠(chǎng)的系統。REG 216保護的緊湊版本也可用，
基本上是一個(gè)標準化的設備機架（參見(jiàn)第節2.3.). 緊湊型可以安裝在開(kāi)放式框架或與其他設備一起安裝在隔間內。2.2.隔間版本2.2.1.操作原理圖2.1說(shuō)明了個(gè)人的基本工作原理
構成完整保護的單元和模塊系統
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.
