ChamanliComposition of dry-type power transformer,

Fault judgment of power transformerOn load commissioning:Chamanli,The rate of transformer is: n = P / pxo%, when the copper loss of transformer is equivalent to iron loss, the rate is very large. Therefore, the load of transformer is: = P / PK. Fully consider the active power loss caused by reactive power in the system software during transformer operation. The load adjustment is: it can be seen from the calculation of load formula that the large rate of transformer does not occur when the load is full, Generally it is about %, but when selecting the transformer capacity, we should select effective transformers according to the load condition and load, so as to make the transformer in the situation of economic development and achieve the goal of power saving.In fact, ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them, safety factor grounding device can be divided into grounding protection,ChamanliPrice of 400KVA dry type transformer,ChamanliDistribution transformer maintenance, anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.Malolos,The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of -A / Min.The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.Oil leakage at looper flange

(III) dry type transformers of KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than m; The distance between the electrified part and the road surface shall not be less than m.The transformer manufacturer will introduce the efficiency of the transformer to youIn fact, safety factor grounding device can be divided into grounding protection, anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.Test results,Dry type transformer companyManufacturing process and steps of dry-type transformer() the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side, it shall be installed on both sides of the low-voltage composite insulator, first take out the low-voltage waterproof sleeve and the on load transformer power switch, then lower the bell cover anchor bolt of the large cover, slowly hang the galvanized steel wire rope with sufficient lifting net weight on the commonly used earrings, wear round steel from top to bottom in the surrounding screw holes, and count the spacing and specifications for easy reinstallation. At the same time, the cable wind shall be added on all sides to ensure that the core international body will not be damaged during the whole lifting process. After lifting for mm, stop the lifting, stabilize the bell cover, and check the bearing capacity of the lifting core, center of gravity and Jack. After everything is normal, lift it again until the bell cover exceeds the relative height of the body, and rotate the crane to place the bell cover on the clean skid.Quality documents,Power transformer manufacturerThe grounding resistance of, high voltage and bottom voltage shall not be less than % (m & omega;) of the original value. The difference between the three-phase mean value of winding resistance measurement at the same temperature shall not exceed %, which shall not exceed % compared with the last accurate measurement result.Connection group structure of dry-type transformerChamanli,Some are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.Seal oil leakageUse fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut), wipe the Fushi blue film remover on the surface and then tighten it after wiping the raw materials on the surface. After drying, the treatment goal can be achieved.
