Tangshan110 kV oil immersed transformerHow to deal with the local deformation of

Oil immersed transformerThe conductor insulation of power transformer is the main part of internal insulation. Some conductors should pass through the middle of electromagnetic coil,TangshanPrice of scb11 series dry type transformer, or between electromagnetic coil, iron yoke clamp and automobile oil tank wall. Therefore, it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength, i.e. insulation spacing.Tangshan,The cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions generally from half a year to once a year;In order to better carry out the experiment of power transformer oil, it is necessary to sample the power transformer oil. The sampling work should be carried out on a dry sunny day. The commonly used containers and sampling methods during sampling do immediate harm to whether the specific quality of the oil can be truly reflected. The oil sample for AC voltage withstand test shall not be less than .kg, and the oil sample for simplified experiment shall not be less than kg.Lambare,It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, laminated glass and other materials very well,TangshanTransformer 35KVA, so as to achieve the pressure management of oil leakage.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, 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.If the power transformer stops running for more than h (if the allowable time should be reduced when the ambient humidity is & amp; gt; %), it should be insulated before putting into use, the insulation resistance from the secondary side to the ground should be ^ mh, and the insulation resistance from the iron core to the ground should be & amp; gt; mfl (note that the grounding device piece should be removed).

The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.The equipment can eliminate the shortcomings found in the patrol inspection, clean the porcelain waterproof casing casing, remove and replace the cracked or brittle leather pad, check and tighten the node replenish the oil with less oil, check and replace the silica gel of the breathing mask, etc.After hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.Variable cost,When sampling in bulk gasoline barrels, samples shall be selected according to % of the number of gasoline barrels, but not less than barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to % of the total number of barrels (bottles).Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?

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.Variable cost,Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management,TangshanOil immersed transformer 2500kVA, which can control the oscillation below .%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.Transformer manufacturers generally adopt IP protective casing, which can avoid the entry of solid dirt with a diameter of more than mm, rats, snakes, cats, birds and other animals resulting in vicious common faults such as short-circuit fault and power failure, and provide a safe natural barrier for the energized part. If the transformer equipment must be outdoors, IP protective casing can be adopted, which can avoid being equally divided with the above IP protective effects However, IP casing will reduce the refrigeration capacity of the transformer, insulated by insulating oil in the circulating system inside the transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.Tangshan,If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.Due to poor sealing, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.(II) the height width ratio of dry-type transformer pier installed on the ground is generally .m, and a guardrail of no less than m shall be installed around it, and a warning sign shall be hung at a prominent position.
