美高尔MWA3xx变压器迷你分析仪说明书

DESCRIPTIONThe Megger MWA3xx Transformer Winding Analyzer is anadvanced 3-phase transformer test system delivering portability, reduced set-up time, increased job-site safety, and effortless productivity. The MWA3xx provides complete ratio, phase and winding resistance measurements for a 3-phase transformer. All ratio and winding resistance tests are performed in one instrument, with only one 3-phase lead-set connection. The MWA3xx utilizes PowerDB as a single software platform saving the user additional time with only one set-up and one easy-to-use test form.The MWA3xx effectively tests:n Power transformers n Distribution transformers nCTs and VTs (PTs)n Motors/generatorsTESTING PERFORMEDThe following tests are easily performed with the MWA3xx, all with one instrument and one 3-phase lead-set connection.n 3-phase turns ratio n 3-phase winding resistancen OLTC/continuity (make-before-break) n 3 phase core demagnetization n Magnetic balance / flux distribution n Excitation currentn Polarity and phase angle deviation n Auto vector detection nHeat-run test3-Phase test connection (no interconnect boxes)3-Phase, 2-Winding Transformers - Resistance on all six windingsOnce connected, the MWA3xx performs DC resistance measurements on all high- and low-side windings withoutreconnection. The test procedure is simple and efficient. Delivering eight-terminal/six-winding resistance measurement capabilitywithout the need for inter-connect boxes saves the user time by testing all six windings without having to disconnect and reconnect leads. The far-end of the measurement cable set is connected to each bushing/terminal of the transformer using a patented adjustable (100 mm – 4 in. opening) Kelvin clamp. This adjustable clamp removes the need for traditional dual leads (I & P) per phase, reducing the connections from 16 to 8 without the worry ofmisconnecting potential (P) for test current (I). The near-end of the cable is connected to the MWA3xx. Selected resistances of bothMWA300/330A3-Phase Ratio and Winding Resistance AnalyzernCombines TTR and resistance testing in one box - faster, more efficient testing n55% smaller, 40% lighter than individual instrumentsnOnly one set of leads required - lighter, smaller and less expensiven One test form - easier, faster to complete n Built-in demagnetizationMWA3xx3-Phase Ratio and Winding Resistance AnalyzerMWA330A with built-in 12-in industrial computer, shown above.HV and LV windings will then be measured. The test sequence can be selected as 6-winding with dual injection simultaneous winding magnetization, up to 4-winding measurement of HV and LV separately, or single-winding test.3-Phase turns ratioComplexity in the measured ratio versus nameplate ratio occurs with most three-phase power transformers due to multipliers, such as √3, which are required to match the measured ratio to the nameplate ratio. Additionally, transformers with zig-zag windings are handled correctly with internal compensation allowing usersto compare nameplate to actual with no corrections needed. The MWA3xx automatically applies the appropriate multiplier which provides a direct comparison to the nameplate ratio.Excitation currentThe excitation current test at low voltage is very useful in locating problems such as defects in magnetic core balance, in magnetic core structure, shifting of windings, failures in the turn-to-turn insulation, or problems in tap changers.Winding balanceWinding balance (also referred to as magnetic balance) is performed to assess the health of the windings, core assembly condition, and flux distribution within the transformer. This test, performed safely and efficiently by the MWA3xx, is a measure of how well balanced (electrically) the transformer is versus nameplate specifications. Check with the factory to ensure your vector group is available with this feature.Phase angle deviationPhase angle deviation is the phase relationship between in-phase vectors of the high-side windings versus the low-side windings. The phase deviation denotes the quality of the core and the winding and should exhibit very low values (0.01 degrees) when the core and windings are functioning properly. Shorted turns, a deteriorated, or damaged core can cause significant changes in the phase deviation values.LTC (OLTC) continuityIn normal LTC operation, continuity between the internal LTC contacts is maintained throughout each complete transition (from one tap position to the next). To check for this continuity, the MWA3xx continually monitors the transition current for each tap position. Any slight discontinuities are detected and reported. Vector recognitionWhen the transformer nameplate data is unavailable, or to confirm compliance to specified nameplate configurations, the MWA3xx provides the capability for automatic vector group detection. PolarityThe MWA3xx quickly and efficiently checks for correct polarity between high and low side windings.Automated heat-run interval testingThe MWA3xx performs automated single or multi-core heat run testing. It uses the standard accepted methods, IEC60076-2-1993 & C57.12.90 2013, for this test, allowing users to perform factory testing automatically. Reports included within software also meets IEEE and IEC standard requirements but does allow manipulation to fit individual customer requirements.Auto core demagnetizationIn order to avoid problems related to core saturation, the MWA3xx comes standard with a core demagnetization function which safely demagnetizes the transformer core after DC testing.PowerDB™ SoftwarePowerDB software provides the unit with a common “user interface” to minimize operator training and provides a seamless interface to the computer application – PowerDB Lite.Two Interface OptionsExternally controlled – MWA300The MWA300 is a “black box” style package that is remote-controlled by PowerDB software running on an external PC (not provided).Built-in 305 mm (12 in.) touch-screen computer –MWA330AThe optional built-in touch-screen computer software provides an industrial, high visibility screen for use on any day – bright or cloudy – and works under the toughest environments. Providing the same test capabilities as the MWA300, the MWA330A comes equipped with an internal computer providing a 305 mm (12 in.) color display with touch-screen interface.FEATURES AND BENEFITSn “One-time” 3-phase connection tests all six windings for faster and safer testing.n No switchbox required, ensuring easier and safer operation.n Unique Kelvin clamps with patented adjustable jaws each open to 100 mm (4-in.) as well as banana plug input for connectionto terminal blocks – no need for special lead sets, and minimal operator error due to lead connections.n Industrial grade 305 mm (12 in.) bright-color touch-screen display available as an option.

The Amaircare 4000VOC ChemFilter is designed to remove VOC’s generated by solvent ink-jet plotters. The 4000VOC is installed directly into the rear of a plotter and creates a negative pressure inside the plotter. The VOC’s that are created in the printing process are drawn into the 4000VOC’s 30 lb. granulated carbon filters which remove a significant amount of the V.O.C.’s. The ‘clean’ air is then vented out of the bottom of the 4000VOC.

MeCaWear 350 产品说明书

PROCÉDURE DE MÉLANGEProportion du mélangeVolume 4 partie de résine (A) : 1 partie de durcisseur (B) Poids 7.3 partie de résine (A) : 1 partie de durcisseur (B)MeCaWear© 350 est un système bi-composant. Une dose complète doit être utilisée pour le mélange comme pour l’application. Ne jamais mélanger une partie seulement de la dose sous peine de ne pas obtenir un dosage convenable.Vérifier que la température du produit est comprise entre 20 et 30 °C (68 et 85 °F). Dans un premier temps, mélanger la résine du composant A et le durcisseur du composant B chacun de leur côté. Vérifier que tout éventuel dépôt de matériau au fond du conteneur soit bien mélangé. Verser doucement le durcisseur B dans la résine A, tout en mélangeant délicatement.Verser d’abord un quart du durcisseur, puis mélanger. Une fois le mélange homogène, verser le reste du durcisseur par petites quantités, tout en mélangeant jusqu’à ce que tout le durcisseur soit ajouté. Mélanger pendant encore 2 minutes jusqu’à l’obtention d’une couleur et d’une consistance homogène. Pour garantir un mélange parfait, racler les parois et le fond du conteneur, puis mélanger encore pendant une minute. En cas d’utilisation d’un mélangeur mécanique, mélanger à petite vitesse pour éviter de faire entrer de l’air dans le mélange. PROCÉDURE D’APPLICATIONUne fois le mélange obtenu, l’application peut débuter immédiatement, aucun temps de pause n’est nécessaire. Le mélange possède une durée de vie en pot réduite. Il produit un dégagement de chaleur par réaction exothermique découlant de la polymérisation. Le mélange peut être réparti dans de petits conteneurs pour préserver sa durée de vie en pot. Le produit peut être appliqué à la brosse ou au rouleau. Appliquer le matériau sur toute la surface pour assurer un mouillage complet de la surface du substrat et garantir ainsi une adhésion correcte.Ne jamais réduire ou de diluer le matériau.PRÉPARATION DE LA SURFACEVérifier que la surface est propre, sèche et exempte de toute contamination. Si nécessaire éliminer toute trace d’huile, de graisse ou autre contaminant susceptible de polluer l’abrasif et de s’imprégner dans la zone sablée. En industrie chimique et des engrais vérifier la présence de contamination aux sels ioniques (chlorures et sulfates) et neutraliser la surface si nécessaire. Ne pas pratiquer l’opération de préparation et de revêtement lorsque le substrat est humide ou situé dans un environnement dont le taux d’humidité est supérieur à 85 %. Sabler à l’aide d’un abrasif angulaire propre. Pour les surfaces en acier, sabler à blanc (SSPC-SP10 ; NACE 2 ; SA 2.5). Protégerla surface avant l’application du revêtement afin d’éviter les dépôts de poussière ou autres contaminants.Remplissage des piqûres / soudures irrégulières -Toute zone présentant une irrégularité de surface liée au soudage ou à l’usure doit être corrigée à l’aide d’un composé de reconstruction métal-polymère, tel que l’un des produits MeCaFix©de la gamme MeCaTeC©. Comme l’ensemble de la surface à revêtir la zone corrigée sera rendue rugueuse avant l’application du matériau de revêtement final. Consulter la notice d’application du composé de reconstruction.Service en eau de mer - Après une immersion en eau de mer, il est recommandé de sabler la surface, puis de laisser reposer la pièce pendant 24 heures avant de la nettoyer au moyen d’un jet d’eau sous pression additionné d’une solution de neutralisation avant de sabler de nouveau pour procéder enfin à l’application du revêtement. SYSTÈME DE PULVÉRISATION À CARTOUCHE MECASPRAYConsulter la notice vidéo et le guide d’utilisation du MeCaSpray©avant utilisation. Préchauffer les cartouches à une température comprise entre 51 et 57°C (125 et 135°F). Ne pas dépasser 62°C (145°F). Secouer la cartouche pour homogénéiser tout éventuel dépôt dans le produit. Régler la taille des disques des pistons à 4:1. Utiliser un mélangeur statique à faible écoulement (buse grise) sans clapet anti-retour à bille (base blanche). Débuter la pulvérisation avec une pression d’air de 5 bars (80 psi). Purger le produit à travers le mélangeur statique pour garantir que le mélange résine / durcisseur soit homogène et que les pistons sont engagés au même niveau dans les deux composants. Régler l’arrivée d’air de l’atomiseur sur 3. Une arrivée d’air plus importante accroît la rugosité de la surface. Régler la vitesse d’avance des pistons au maximum à l’aide du curseur. Maintenir une distance minimum de 40 cm (16 pouces) par rapport à la surface tout au long de la pulvérisation. Avant de pulvériser sur la pièce, toujours actionner la gâchette dans une direction de proximité jusqu’à l’obtention d’un mélange pulvérisé bien homogène.SAPPLICATION AU PULVÉRISATEUR À BRAS SANS AIR OU MULTI-COMPOSANTConsulter Castolin Eutectic pour obtenir le guide et les recommandations de réglage pour l’utilisation d’un équipement de pulvérisation à bras sans air ou chauffé multi-composant pour appliquer ce produit.APPLICATION PAR PULVÉRISATIONAvant de procéder à l’application par pulvérisation, griffer à l’aide d’une brosse toutes les soudures continues ainsi que les arêtes. Appliquer le revêtement sur les zones griffées suivant une épaisseur maximale de 0,50 mm par passe. L’épaisseur spécifiée sera obtenue en suivant une technique d’application multipasses croisée.DURÉE DE RÉTICULATIONEn cas de service en environnement chimique, le revêtement doit sécher pendant 7 jours complets. La réticulation peut être forcée pendant 6 heures à 50°C (120°F) pour accélérer la remise en service en environnement chimique. La température de pulvérisation et celle du substrat affectent la durée de réticulation du revêtement. Plus la température est élevée, plus la réaction est rapide.SÉCURITÉAvant utilisation, consulter la fiche de données de sécurité (FDS) disponible au téléchargement sur /fr-FR/msds-portal.Suivre les procédures d’entrée en espace confiné ou de travail si nécessaire.Porter une protection de sécurité pour les yeux et une protection complète pour la peau, notamment des gants résistants aux substances chimiques. Porter un respirateur approuvé par le NIOSH en présence de brumes.Consulter la fiche de données de sécurité avant d’appliquer ce produit.Déclaration de Responsabilité: En raison des variations inhérentes à des applications spécifiques, les informations techniques contenues dans les présentes, y compris toutes informations relatives à des applications ou à des résultats de produits suggérés, sont présentées sans déclaration ni garantie, explicite ou implicite.
