1). 戶外安排的接線盒或者信息臺-IP54,以及恒溫要求右230 V交流防凝結(jié)加熱器控制并且裝備有隱蔽的疏水孔。
2). 輔助開關(guān)和相關(guān)終端IP54 (1),但帶有加熱器控制開關(guān),在相同的電路上與其它儀器通用。
3). 戶外分線盒 - IP54
4). 戶外儀器 - IP65
5). 戶外電動機(jī) - IP54
6). 室內(nèi)的控制繼電器和低交流的電壓,以及直流開關(guān)柜-IP41-的恒溫要求通常由230 V交流防凝結(jié)加熱器和指示燈控制。
5.7.2. 成套開關(guān)設(shè)備編組站信息臺
無論哪里有要求,對每個(gè)電路開間來說,必須提供一座戶外安排的編組站或者信息臺給這個(gè)編組站全部輔助設(shè)備的相關(guān)電路, 例如:匯流排選擇器和線隔離開關(guān), 電流和電壓變壓器等,通過樹干多核心電纜,對繼電控制面板進(jìn)行控制。
信息臺將配有必要接線板, 填料壓蓋板,等,提供給多核心電纜的終端。
信息臺為獨(dú)立式結(jié)構(gòu)和不受氣候影響和防蟲害的鋼結(jié)構(gòu)設(shè)計(jì)。
全部固定裝置都裝備有不可缺少的門和鎖定規(guī)則。門必須采用硬質(zhì)材料,采用適于指定氣候狀況,不受氣候影響的密封材料。
信息臺的通風(fēng)采用防蟲害的百葉窗,包括連接在框架上黃銅薄紗屏,這樣可以對開關(guān)柜內(nèi)部進(jìn)行保護(hù)。

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 Fuse installation should be carried out will be so, when the drainage and circuit is started, withdrawn and replaced easily.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.

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.
