5.6.3. 开关保险丝和隔离开关
每开关保险丝或者隔离开关装置，必须单独安装在一个金属分隔间内并且由一个装有绞链的金属门与开关机制联锁以便：
当开关关闭时，门不能打开。
门在打开时，自动把开关锁定在"关闭"位置。设备考虑到允许故意释连锁装置的情况，方便在运行过程中观察到开关的位置。
绝缘层用于隔离开关的保险丝和中性连接，当分隔间的门已经打开保险丝的入口时，内部金属屏幕将有效地保护后者的连接。
开关保险丝可以是保险丝的结合接通类型或者单独装置的开关。 无论发生哪种情况，连锁将提供防止接入保险丝入口，直到相关开关断开，制定符合在"打开"和“非工作状态”中的挂锁开关的规定。
开关必须有单独的快速启动和快速断开操作，操作的速度完全适于接通与电动机电路相关的电感负载。
5.6.4.保险丝
保险丝必须是HRC盒式类型，预期的故障率水平不少于40 kA并符合BS 88或者IEC 60269的规定。保险丝的安装必须将是如此进行，当相关汇排流和电路是启动时，容易撤回和替换。
5.6.5.配电板和保险丝面板上的连锁
在配电板和保险丝面板的输入电路不配有保险丝或者断路器，电路在每种情况点供应的进行保护。其它400 V面板电路之间连接器在两个面板配有保险丝或者断路器。
配电板将配有电力或者机械关键类型卡斯特尔连锁，防止两种正常的引入的供电情况。
5.6.6附件
以下的附件在配电板上使用。
1)电缆终端
控制电缆的终端符合IEC 60439规定。
2). 接地
配电板，保险丝板和配电板山的稀土金属，必须一同联结并且与主站接地系统进行地接。接连接地采用150 mm2的横截面积裸露铜扁线。
5.7.分线盒，接线盒和编组站信息台
5.7.1.总则
全部分线盒，接线盒和编组站信息台都采用由钢或者铸铁建造。每个部件都必须装配有接地螺栓。
全部主要设备都必须进行安排，这样在接线盒或者信息台的前面就可以接入。
电子仪器的围护结构将符合1992(655490)的IEC 60529类的下列保护规定。
1). 户外安排的接线盒或者信息台-IP54，以及恒温要求右230 V交流防凝结加热器控制并且装备有隐蔽的疏水孔。
2). 辅助开关和相关终端IP54 (1)，但带有加热器控制开关，在相同的电路上与其它仪器通用。
3). 户外分线盒 - IP54
4). 户外仪器 - IP65
5). 户外电动机 - IP54
6). 室内的控制继电器和低交流的电压，以及直流开关柜-IP41-的恒温要求通常由230 V交流防凝结加热器和指示灯控制。
5.7.2. 成套开关设备编组站信息台
无论哪里有要求,对每个电路开间来说，必须提供一座户外安排的编组站或者信息台给这个编组站全部辅助设备的相关电路, 例如：汇流排选择器和线隔离开关, 电流和电压变压器等,通过树干多核心电缆，对继电控制面板进行控制。
信息台将配有必要接线板, 填料压盖板,等,提供给多核心电缆的终端。
信息台为独立式结构和不受气候影响和防虫害的钢结构设计。
全部固定装置都装备有不可缺少的门和锁定规则。门必须采用硬质材料，采用适于指定气候状况，不受气候影响的密封材料。
信息台的通风采用防虫害的百叶窗，包括连接在框架上黄铜薄纱屏，这样可以对开关柜内部进行保护。

5.6.3. Switch and isolating switch fuse
Each switch fuse or disconnecting switch device which shall be installed separately in a metal inside the compartment and by a metal door with hinge and switch mechanism interlocking so that:
When the switch is closed, the door cannot be opened.
When the door opened, automatic switch lock in the "off" position, equipment shall be permitted to release interlock, covenanting in the observed during the operation of the switch position.
Insulation shall be used in isolating switch fuse and neutral connection, when the compartment door already open the entrance of the fuse, internal metal screen will effectively protect the latter's connection.
Switch fuse can consist of a combination of fuse type or single device to switch. No matter what happens, chain will provide to prevent access to fuse the entrance, until the switch, formulates in the "open" and "the provisions of the padlock switch in the non-work state".
Switch shall have a separate quick start and quick disconnect operation, the speed of the operation completely suitable for connected with the motor circuit inductance load.
5.6.4. Fuse
It is applicable to apply HRC fuse box type, the expected level of failure rate of not less than 40 kA and satisfy the requirements of BS 88 or IEC 60269. Fuse installation should be carried out will be so, when the drainage and circuit is started, withdrawn and replaced easily.
5.6.5. Switchboard and fuse panel on the chain
Switchboard and the fuse panel input circuit is not equipped with the fuse or circuit breaker, in each case the circuit supplies for their own protection. Other 400 V panel circuit connector between two panels are equipped with the fuse or circuit breaker.
Distribution board will be equipped with electrical or mechanical key type castle chain, to prevent the introduction of the two kinds of normal power supply.
5.6.6 Attachment
The following attachments used on board.
1) Cable terminal
The terminals of the control cable comply with IEC 60439.
2.) Ground
Distribution board, the fuse board and distribution board mountain of rare earth metals, must join together and to meet with the main grounding system. Successive grounding with 150 was the cross-sectional area of bare copper flat wire.
5.7. Cable box, junction box and the info of the marshalling station
5.7.1. General
All cable boxes, junction box and the info of the marshalling station is built by steel or cast iron. Each part must be equipped with grounding bolt.
All major equipment must be arranged so that in front of the junction box or the info can access.
Palisade structure of the electronic instrument would be in the IEC 60529 of 1992 (655490) class the following protection regulations.

2.) Related auxiliary switch terminal IP54 (1), but with a heater control switch, in the same circuit and other common instrument.
3). Outdoor cable box - IP54
4). Outdoor equipment - IP65
5). Outdoor motor - IP54
6). Indoor control relay and low ac voltage, as well as the dc switchgear - IP41 - usually requires constant temperature is controlled by a 230 V ac prevent condensation heater and light.
5.7.2. Complete switchgear the info of the marshalling station
No matter where there is a requirement, for each circuit studio, you must provide a outdoor arrangement of marshalling yards or the info to the marshalling yards all ancillary equipment related circuit, such as: bus selector and line isolating switch, current and voltage transformer, etc., through multicore cable trunk, to control the relay control panel.
The info will be equipped with necessary wiring board, packing pressure plate, etc., provided to multicore cable terminal.
I called information for independent type structure and is not affected by the climate and the steel structure design of the pest.
All fixtures are equipped with indispensable door and locking rules. Door must use hard material, the use of suitable for the specified climate condition, is not affected by the climate of sealing material.
