Abstract
A kind of train Box of electric machine electromagnetic shielding method, all need carry out the electromagnetic shielding part for the rack casing, all side plates and door all adopt electric conducting material to make, and carry out surface treatment and electrophoresis and add plastic-blasting and handle, the protective plate of all outer panels and inside and section bar annex inside are and conduct, with the conductivity of guard box surface.And all adopt the ROXTEC electromangnetic spectrum of prestige figure for the inlet wire position at casing top or other positions, install additional and clamp the formula conductive rubber flexibly.All side plates and Men Bian tie synapsis mutually with the matrix skeleton, all adopt the sealing of electromagnetic shielding foaming conductive rubber, and it can closely be compressed with framework section bar, have realized good effectiveness again, have also improved vibration resistance.At door knot center-line joint place, also adopt conductive magnetism screen rubber material seal and all adopt the conductive paint spraying inside and outside, realized the good effectiveness of door.
Description
Technical field
The invention belongs to a kind of configuration and arrangement of train electrical appliance cabinet, be meant the configuration and the arrangement of network control flow cabinet-type air conditioner case on the train especially, and the cabinet configuration and the structural form of the network control screen electromagnetic compatibility mode that cabinet adopted.
Background technology
The casing that carries out electromagnetic shielding be on the casing of electric device electric device is a kind of safeguard procedures that prevent that external electromagnetic interference from taking, this is for the stability and the reliability that improve the electric elements operation in the cabinet, and all be very beneficial the useful life that prolongs electric elements.Especially the electromagnetic compatibility mode of taking with network control screen cabinet for locomotive is to avoid and externally produce a kind of electromagnetic shielding safeguard procedures that electromagnetic interference is taked for the various precision electronic elements in the screen cabinet, stability and reliability for locomotive operation have very important significance.The various control flow cabinet of existing locomotive casing is to realize by integral solder and common dust seal mostly, though this way also can reach railway IEC standard substantially, leeway also improves a lot.Though and the framework form of the integral solder of existing control flow cabinet casing casing is all more favourable for the bulk strength and the rigidity of cabinet, the framework form of this integral solder also exists some shortcomings.It is big that one is exactly that the board wall formula framework of this integral solder exists distortion, the inaesthetic deficiency of profile; Two to be exactly that structure seems overweight for it, this mainly is because the wallboard of this class machine frame is all non-dismountable, so just must consider to leave enough installations and service clearance when the installation of internal components, this certainly will will strengthen the structure of casing, therefore, the necessary improvement.The someone proposes to change existing locomotive control screen cabinet casing into skeleton jigsaw structure at present, but realize control flow cabinet box frame formula jigsaw structure, at first just must solve the electromagnetic shielding problem of skeleton jigsaw structure, and the electromagnetic shielding of the various control flow cabinet of existing locomotive casing is also found to be necessary further raising in actual use.
Summary of the invention
The objective of the invention is to, at the deficiency of the electromagnetic shielding of existing power locomotive electric cad system device box, it is better to propose a kind of effectiveness, particularly can be applicable to the electromagnetic shielding method of skeleton jigsaw structure control screen cabinet casing.
According to the technology implementation scheme that purpose of the present invention proposed be: control flow cabinet casing of the present invention is to take the jigsaw textural association to form by matrix skeleton and side plate.All all side plates and doors that need carry out electromagnetic shielding part all adopt galvanized sheet to make for the rack casing, and carry out surface treatment and electrophoresis and add plastic-blasting and handle, the protective plate of all outer panels and inside and section bar annex inside are and conduct, with the conductivity of guard box surface.The position that all side plates and door combine with the matrix skeleton has adopted foaming electromagnetic shielding conductive elastomeric material and conductive fabric as seal, closely compresses with framework section bar, has both guaranteed the sealing conductive effect, has improved vibration resistance again.Be characterized in: the matrix skeleton is to be formed by casing required size and planform soldered by standard nine fold-type materials and section bar three-way piece; protected the alumin(i)um zinc alloy layer unaffected; and should welding itself have good conductivity, the skeleton integral body that is welded into all becomes an electric conductor.The section bar of matrix skeleton also all adopts the plate golding aluminium zinc alloy technology, and electrophoretic process has been carried out one on the surface again, and inner fixedly section bar has also all adopted the plate golding aluminium zinc alloy processing.At door knot center-line joint place, also adopt conductive magnetism screen rubber material seal and all adopt the conductive paint spraying inside and outside, realized the good effectiveness of door.In addition, Nei Bu ventilation and heat all adopts fan and the ventilating opening with effectiveness and dustproof effect.
Adopt this kind electronic shield technology,, can make the electronic shield effect of control flow cabinet can reach 60DB to 100DB, can be satisfied with the requirement of the locomotive control screen cabinet casing electromagnetic shielding of skeleton jigsaw structure fully by analysis with actual test shows.
