产品详情资料   

所有19英寸HIMA组件（如盲板和子架）的可触摸板
导电钝化（ESD保护，ESD=静电放电）。保险箱
内置组件（如子架）与机柜之间的电气连接
通过带爪的俘虏螺母。定位爪穿透回转框架（1）的表面，因此
确保安全的电气接触。所用的螺钉和垫圈由级材料制成
钢，以避免电腐蚀（2）。
机柜框架（3）的部件焊接在一起，因此它们构成一个
导电结构元件。摆动框架、门、安装轨道和安装
板（如果存在）通过短接地与机柜框架导电连接
横截面积为16 mm2或25 mm2的接地母线。接地母线覆盖有黄色/绿色识别护套（5）。
顶板通过四个吊耳拧入机柜框架。侧板和后部
面板通过接地夹（7）（见图8）通过螺钉与机柜框架和底板导电连接
图7：子架的接地连接
作为标准，机柜中已经安装了两条M 2500（4）母线，并已连接
通过25 mm2接地带（5）连接至机柜框架。此外，母线（4）可以
用于仅通过拆除接地带与地面分离的电位（例如
现场电缆屏蔽）。为了连接客户接地，机柜框架（6）处提供了一个M 8螺栓。

8.5.3互连多个开关柜的接地端子
接地必须具有尽可能少的干扰电压。如果无法实现，则必须为控制装置安装单独的接地。

8.6 HIMA通信系统中数据线的屏蔽
HIMA通信系统中数据线的可靠屏蔽通过以下方式实现
措施：
总线用户（H41q、H51q）至总线终端（H 7506）的电缆屏蔽连接1）在总线用户侧建立。通过插头盒和金属正面
板通过PCB布局与PE机柜接地建立连接。另一边的
电缆屏蔽层未连接。
H 7505接口转换器的连接2）也通过插头在一侧建立
案例与顶帽的连接All touchable plates of the 19-inches HIMA components (e. g. blind plates and subracks) are
electrically conductive passivated (ESD protection, ESD = Electrostatic Discharge). The safe
electrical connection between built-in components, such as subracks, and the cabinet is made
via captive nuts with claws. The claws penetrate the surface of the swing frame (1) and thus
guarantee a safe electrical contact. The screws and washers used are made of high-grade
steel to avoid electrical corrosion (2).
The parts of the cabinet framework (3) are welded together and therefore they make up an
electrically conductive constructional element. Swing frame, door, mounting rails and mounting
plates (if existing) are conductively connected to the cabinet framework via short earthing
straps with a cross section of 16 mm2 or 25 mm2. The earthing straps are covered with a yellow/green identifying sheath (5).
The top plate is screwed to the cabinet framework via four lifting eyes. Side panels and rear
panel are conductively connected via earthing clamps (7) (see Figure 8) to the cabinet framework as well as the bottom plate via screws
Figure 7: Earthing connections for subracks
As a standard, two M 2500 (4) bus bars are already installed in the cabinet and are connected
to the cabinet framework via 25 mm2 earthing straps (5). Additionally, the bus bars (4) can be
used for potentials separated from the earth just by removing the earthing straps (e.g. for the
screens of field cables). For the connection of the customers earthing an M 8 screw bolt is provided at the cabinet framework (6).

8.5.3 Interconnecting the Earth Terminals of Multiple Switchgear Cabinets
The earth must be with less interference voltage as possible. If this cannot be achieved, a separate earth for the control has to be installed.

8.6 Shielding of Data Lines in the HIMA Communication Systems
Reliable shielding of data lines in HIMA communication systems is achieved by the following
measures:
The connection 1) of the cable shield from the bus subscriber’s (H41q, H51q) to the bus terminals (H 7506) is established on the bus subscriber’s side. Via the plug case and the metal front
plate a connection is established via the PCB layout to the PE cabinet earth. The other side of
the cable shield is not connected.
The connection 2) of the H 7505 interface converter is also established on one side via the plug
case. The connection to the top hat
