After hours of continuous trial operation with a certain load,VenezuelaParameters of oil immersed power transformer, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.When the full load test is carried out and everything is normal, the load can be connected.Venezuela,Two point grounding device of iron core caused by residual welding scar;Method and process of taking oil sample of power transformerQuba,Fault judgment of power transformerThen clamp the branch pipe with your thumb,Venezuela10kV dry type transformer, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice,VenezuelaDry type transformer protection configuration, and then draw the oil sample.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.For oil transformer oil replenishment, unused transformer oil conforming to the new standard should be selected first. In addition, the oil with the same basic, same brand and same additive type is expected to have a stronger effect. The characteristics of the oil should not be lower than that of the oil in mechanical equipment. When the new remaining oil is less than %, if there is more new remaining oil, oil shall be added before oil type Chromatographic analysis and pressure test shall be carried out to establish that there is no oil stain, and the acid value and dielectric loss shall not exceed the oil in the machinery and equipment.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,Sound in case of phase failureIf 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.Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;

The noise of dry-type transformer belongs to low-frequency noise. In a small area, most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building, and then causes gas vibration noise, which is then scattered to the ears of consumers. Although the amount of noise is not very large, the dispersion spacing and adverse effects are very large.device management,How much is the power transformerTransformer inspection nose sniffing methodLoose core screwVenezuela,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.The oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.Oil leakage of cast iron parts
