Embodiment
As shown in Figure 1, bus duct has rated voltage, rated capacity, test report, Pareto diagram.Various shaped steel, the fastener of making support should pass through preservative treatment, and should adhere to specification; Expansion bolt, bolt, nut, pad, spring washer should be zinc coatings.Other material is as antirust paint, finish paint, welding rod etc.Main facility: workbench, bench vice, cutting machine, bench drill, electric hammer, die head threading machine, tap, electric welding machine, torque spanner, spanner etc.Testing tool: steel tape, steel set-square, level gauge, plumb bob, 500V megohm meter etc.Hole to be provided and built-in fitting are finished, and each layer of electric shaft ground is carried out.The operating procedure technological process: equipment is unpacked and is checked inspection → rack making → support installation → bus duct installation → trial run examination.Should make according to design and product documentation regulation.Specific requirement is: (1) according to the structure type of job site, support should adopt angle steel, channel-section steel or round steel to make, and can adopt 4 kinds of forms such as "-", " w ", " ", " well " type.(2) stent applications cutting machine blanking, processing dimension worst error are 5mm.With bench drill, electric hand drill boring, forbid to use the gas cutting perforate, the aperture must not surpass diameter of bolt 2mm.(3) the suspension rod screw thread should adopt die head threading machine or tap processing, and fracture of wire must not be arranged.(4) support and suspension bracket are made and are finished, and should remove the weldering of removing slag, and brush antirust paint and finish paint.Support install bus duct the corner and must mounting bracket with distribution box, cabinet junction, the straightway set spacing should be greater than 2m, support and suspension bracket must be installed firmly.Necessary backguy or ceiling hammer when support and suspension bracket are installed put down vertically to guarantee the horizontal of support in a row or suspension bracket, and spacing are provided with support or suspension bracket in accordance with regulations.Bus duct vertical run support: on every floor plate, every bus duct should be installed 2 channel-section steel supports, and an end is embedded within the walls, and the other end is fixed on the floor with expansion bolt.When two layers of channel-section steel support surpass 2m up and down, "-" font angle bar frame need be installed on the wall, angle bar frame is fixed on the wall with expansion bolt, and angle bar frame is welded on the angle bar frame, should guarantee that the vertical plane of all angle bar frames 2 in the vertical shaft becomes same vertical plane.Can adopt " w " type support, be fixed on the top board or on the wallboard with expansion bolt.The bus duct horizontal crouch to be installed, the installation of lying on one's side of bus duct level, and the weld of support should be removed welding slag, and brushes antirust paint and finish paint, must not pollute building.Press the bus duct Pareto diagram, begin upwards, install forward from initiating terminal (or electric shaft porch), its jack switch case height should meet design or bus duct factory regulation.(4) 1. vertical installation of bus duct measure good position earlier at the through-flooring place, with bolt two angle bar frames and bus duct are connected, antirattle spring, pad on the bolt sleeve that provides with manufacturer again, fastening nut is fixed on the channel-section steel support, and spring support group number is stipulated according to bus duct pattern and capacity by factory.With horizontal pressure foot and bolt, nut, flat shim, spring washer bus duct is fixed on "-" font angle bar frame, upwards installs by joint then, guarantee the perpendicularity (use plumb bob and hang vertical line) of bus duct, add cover plate, use bolted in end.The bus duct level is installed horizontal and is crouched and install: with horizontal pressure foot and bolt, nut, flat shim, spring washer bus duct (flat crouching) is fixed on the angle steel suspension bracket.With side dress pressing plate and bolt, nut, flat shim, spring washer bus duct (lying on one's side) is fixed on " " type angle steel suspension bracket.Guarantee the levelness of bus duct, add terminal cover, and use bolted in terminal.Dock connects: save bus ducts to connecting with two earlier, put into a bus connecting plate and insulation board every bus joint both sides, penetrate insulated bolt again, add flat shim, spring washer, the nut of screwing on then, fastening with torque spanner, the moment that reaches regulation gets final product, and fixes cover plate up and down at last.Bus duct connects the Tightening moment with insulated bolt: M10 is 55Nm; M12 is 75Nm; M16 is 115Nm.After 5 Installation Considerations (1) bus duct installs, further adjust, to guarantee the perpendicularity and the levelness of bus duct.When (2) the bus duct straightway is installed, to add a joint expansion joint about every 100m.(3) in installation, must carry out the measure that water leakage and anti-foreign matter enter.(4) bus duct earthing of casing bridging plate connects and should firmly prevent to become flexible, and forbids to weld, and bus duct shell two ends should be connected with protective earthing (zero) line.(5) finish the installation of inlet wire case and plug-in type switch-box by design drawing regulation.After 6 trial runs are checked and accepted (1) bus ducts and installed, should put in order, clean clean, shake with megohmmeter and to survey alternate, Relative Zero, relatively insulation resistance, and perform record.(2) after checkout adheres to specification, send electric no-load running 24h no abnormal phenomenon, handle the examination formality, hand over construction unit to use, submit the examination data simultaneously to.(3) examination data comprises: the receipt of handing over, design alteration record, work certificate, specification, test record, preoperation record etc.Attached: plug type bus duct is installed sea market quality standard 1. assurance project (1) models, specification, quality and must be adhered to specification, and product testing result must compliant.Insulation resistance should be greater than 10M Ω.(2) the spring-loaded device is installed and should be met design and product technology requirement.(3) temperature rise of bus duct joint should meet the product technology requirement.2. elementary item (1) bus duct installation qualification: 1. the suspension rod of suspension type bus duct or suspension bracket should have the adjustment bolt, bus duct vertically is installed is crossed the floor place elastic bearing frame should be set.The spacing of fixing point should meet product requirement, then must not be greater than 2m during as the product no standard.2. the connection of each section bus duct shell should be removable, and should there be the above clear distance of 3mm adjacent running through between busbar joint set bolt packing ring, and the fastening force of bolt is apart from the requirement that should meet product.Good: on qualified basis, the bus duct joint must not be arranged on wall, floor place, and sheath should be arranged, should be anti-blocking complete when passing the area of fire protection partition wall, and bus duct is anticorrosion complete.(2) annex installation qualification: the annex of bus duct, must adhere to specification as the installation of inlet wire joint, expansion joint, commutation joint, coupling box, the position is set should be convenient to operation, repairs, installation should be firm.Good: on qualified basis, used fix bolt-unfastening preventing packing ring is complete, paints complete.(3) ground connection (connecting to neutral) is qualified: each section bus duct should have jumper between the groove shell except that grounding requirement up to specification, and the earth connection specification meets corresponding standard, and reliable ground.When system is five-wire system system and PE line when directly reliably being connected with the bus duct shell, can consider not establish jumper, but must have the relevant technologies of manufacturer to prove.Good: on qualified basis, line alignment is reasonable, and colour code is correct, not contaminated equipment and building after the brushing.3. permissible variation project (1) set spacing is not more than 2m, and permissible variation is 100mm; The bus duct centreline spacing is not less than 0.4m, permissible variation 10mm side by side.(2) the perpendicularity permissible variation of bus duct is 1.5mm/m, and the total length permissible variation is not more than 10mm;
