2、當(dāng)容許運用電纜橋架系統(tǒng)軟件組成接地主干線控制回路時要合乎以下規(guī)定。電纜橋架頂端中間聯(lián)接電阻器應(yīng)不超0.00033歐母，接地孔應(yīng)絕緣層鍍層。在1KV及下列中性點立即接地系統(tǒng)軟件中，受電設(shè)備的接地與系統(tǒng)軟件中性點接地相接。配有處動斷開供電系統(tǒng)裝軒時，電纜橋架的級長方位金屬材料截面積應(yīng)不低于標(biāo)準(zhǔn)值。

2. When it is allowed to use the cable tray system software to form the main grounding trunk control circuit, the following requirements shall be met. The middle connecting resistor at the top of the cable bridge shall not exceed 0.00033 ohm female, and the grounding hole shall eliminate the insulation layer coating. In the system software of 1KV and below neutral point immediate grounding, the grounding of the receiving equipment is connected with the system software neutral point grounding. When the power supply system is equipped with a dynamic disconnect, the sectional area of the metal material in the long direction of the cable tray shall not be lower than the standard value.

3、沿電纜橋架總長另敷設(shè)接地主干線時，段(包含非平行線段)電纜橋架應(yīng)少有一點與接地主干線靠譜聯(lián)接。

3. When the grounding main line is laid along the total length of the cable bridge, the first section (including non-parallel section) of the cable bridge shall be connected with the grounding main line at least at one point.

4、針對震動場地，在接地位置的相接處應(yīng)設(shè)備彈簧圈。客戶如需槽式電纜橋架的別的種類規(guī)格型號可來圖來函和面洽訂購。槽式直達(dá)金屬表面處理分成靜電噴塑、熱鍍鋅、噴涂三種，用靜電噴塑時請使用接地板。

4. For the vibration site, the spring coil shall be installed at the junction of the grounding position. If customers need other types, specifications and models of trough-type cable tray, they can order by drawing, letter and face-to-face contact. The trough direct metal surface treatment can be divided into three types: electrostatic spraying, hot galvanizing and spraying. Please use the grounding plate when using electrostatic spraying.

槽式電纜橋架水準(zhǔn)敷設(shè)時，宜按荷載曲線圖選擇跨距開展支撐點，跨距一般為1.5～3.0m。豎直敷設(shè)時，其固定不動間隔不適合超過2m 針對電纜橋架的界定、型號規(guī)格編號、規(guī)定、實驗方式，針對電纜橋架檢測標(biāo)準(zhǔn)、標(biāo)示、運送和存儲等,本規(guī)范適用工業(yè)生產(chǎn)與工業(yè)建筑室外、高壓低壓輸變電工程項目的電纜橋架。

When the trough-type cable tray is laid horizontally, it is advisable to select the span to carry out the support point according to the load curve, and the span is generally 1.5~3.0m. When laying vertically, the fixed fixed interval shall not be more than 2m. For the definition, model, specification number, regulation and test method of cable bridge, and for the detection standard, marking, transportation and storage of cable bridge, this specification is applicable to the cable bridge of outdoor, high-voltage and low-voltage power transmission and transformation projects of industrial production and industrial buildings.

在挑選槽式電纜橋架的荷載級別時，電纜橋架的工作中均布荷載不可超過選定電纜橋架荷載級別的額定值均布荷載，假如槽式電纜橋架的抗震支架的具體跨距并不等于2m時，則工作中均布荷載應(yīng)符合要求。各種各樣部件及抗震支架在考慮相對荷載的標(biāo)準(zhǔn)下，其規(guī)格型號規(guī)格應(yīng)與拖盤、梯架的平行線段、彎通系列產(chǎn)品相符合。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://m.ymmgjx.net進(jìn)行咨詢吧！

When selecting the load level of trough-type cable tray, the uniformly distributed load in the work of the cable tray shall not exceed the rated value of the selected cable tray load level. If the specific span of the seismic support of the trough-type cable tray is not equal to 2m, the uniformly distributed load in the work shall meet the requirements. Under the standard of considering the relative load, the specifications, models and specifications of various components and seismic supports should be consistent with the parallel section of the towing plate and ladder and the bend-through series products.
