大型鋼板庫常用的檢測設(shè)備及避雷方案的設(shè)計 Design of Common Testing Equipment and Lightning Protection Scheme for Large Steel Plate Warehouses大型鋼板庫直觀地顯示設(shè)備的運行狀態(tài),在控制室內(nèi),各種控制信號都集中在控制板或計算機上。操作簡單、快速、安全可靠。操作員只需在控制室操作,即可搬運整個大型鋼板庫并向前移動。測試設(shè)備也配備齊全。 The large steel plate warehouse intuitively displays the operating status of the equipment, and in the control room, various control signals are concentrated on the control board or computer. Easy to operate, fast, safe and reliable. The operator only needs to operate in the control room to transport the entire large steel plate warehouse and move it forward. The testing equipment is also fully equipped. 大型鋼板庫中常用的檢測設(shè)備如下:物料品質(zhì)快速檢測設(shè)備、測溫設(shè)備、料位設(shè)備、監(jiān)控設(shè)備等安全運行設(shè)備。大型鋼板庫存儲容量大:單個倉庫的存儲容量為10000-500000噸,可以形成更大的存儲組。 The commonly used detection equipment in large steel plate warehouses includes rapid material quality detection equipment, temperature measurement equipment, material level equipment, monitoring equipment, and other safety operation equipment. Large steel plate inventory storage capacity: The storage capacity of a single warehouse is 10000-500000 tons, which can form larger storage groups.
Convenient storage: According to different materials and manufacturer conditions, material storage methods can be forward machine storage, chute storage, or power pipeline storage. Overall planning: The storage body is cylindrical, the top and bottom of the storage are spherical, and the bottom of the storage is cylindrical.
According to the principles of the lightning protection and grounding system for large steel plate warehouses, the lightning protection scheme for large steel plate warehouses should meet the lightning protection requirements for secondary lightning protection buildings in the current standard "Building Lightning Protection Scheme Standard".
Install lightning protection nets, lightning rods, or use metal components as lightning arresters at the top of the tower. The lightning protection network, lightning rods, metal components, and operation methods should be connected to the down conductor. The method for setting up down conductors is as follows: 大型鋼板庫的防雷方案應(yīng)采用大型鋼板庫頂部的圍欄和大型鋼板庫上的廊道作為避雷器。倉庫上的廊道與倉庫頂部的圍欄采用焊接連接。引下線可采用鍍鋅扁鋼,鍍鋅扁鋼截面、厚度都不應(yīng)小于規(guī)定的尺寸。操作塔引下線及各料倉引下線數(shù)量不少于2根,間距不大于18m,對稱布置。 The lightning protection scheme for large steel plate warehouses should use the fence on the top of the large steel plate warehouse and the corridor on the large steel plate warehouse as lightning arresters. The corridor on the warehouse is connected to the fence on the top of the warehouse by welding. The down conductor can be made of galvanized flat steel, and the cross-section and thickness of the galvanized flat steel should not be less than the specified size. The number of down conductors for the operation tower and each silo shall not be less than 2, with a spacing of no more than 18m, symmetrically arranged. 接地設(shè)備可采用根部鋼筋,縱向和橫向鋼筋應(yīng)焊接,沖擊接地電阻不應(yīng)大于10Ω。 庫組底座未連接,底座留有變形縫時,應(yīng)采用扁鋼或圓鋼焊接,并留有足夠的變形量。鍍鋅扁鋼截面、厚度都不應(yīng)小于規(guī)定的尺寸;圓鋼直徑不小于12mm。 Grounding equipment can use root reinforcement, and longitudinal and transverse reinforcement should be welded. The impact grounding resistance should not exceed 10 Ω. When the base of the warehouse group is not connected and there are deformation joints left on the base, flat steel or round steel should be welded with sufficient deformation. The cross-section and thickness of galvanized flat steel should not be less than the specified dimensions; The diameter of round steel shall not be less than 12mm. 技術(shù)設(shè)備的機架和金屬管應(yīng)作防靜電接地,接地電阻不大于100Ω。 防靜電接地、防雷接地和維護(hù)接地設(shè)備應(yīng)合并,接地電阻應(yīng)滿足最小值的要求。 The racks and metal pipes of technical equipment should be grounded for anti-static purposes, with a grounding resistance not exceeding 100 Ω. Anti static grounding, lightning protection grounding, and maintenance grounding equipment should be combined, and the grounding resistance should meet the minimum requirement. |
