How much is the power transformerThe no-load impulse closing working voltage shall not exceed % of the working voltage marked on the gear of the transformer, the closing frequency shall be times, the delay time after power receiving shall not be less than min,Many people probably don't know much about the power distribution transformer manufacturers. In fact, you must pay attention to the following points. Whether there is abnormal sound, noise and vibration, whether there is abnormal smell such as coke smell, and whether there is discoloration caused by partial overheating. Ventilation is good. In addition, we should also pay attention to the following aspects.Solenoid insulation deteriorationFundacion,The tap changer of power transformer shall also have strong insulation. kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.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, 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.Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;

Power transformer plantThe transformer manufacturer said that the selection should be based on the application environment of the dry-type transformer. For the extremely extreme environment, the dry-type transformer should be poured with epoxy resin glue. Because this kind of environment does not need to heat the dry-type transformer, it can operate immediately. However, for the general application environment, the class H dry-type transformer can be used.Oil leakage at electric welding positionPrice,The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, it will affect the whole power circuitIf 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,EssenRecycling of waste box type transformer, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.

The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core,EssenFully sealed oil immersed transformer, which is stacked at the degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust, and has sound insulation and noise reduction.Quality improvement,When the whole process of winding wave of oil immersed transformer is calculated by using the marking method, the winding of oil immersed transformer is generally divided into multiple modules, and each module is replaced by an equivalent circuit, and its power circuit includes an inductance and vertical capacitance, a capacitance to ground or capacitance between windings, They also have mutual inductors between the inductors of each module and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.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,Essen1250 dry type transformer size, 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 %, there is generally no problem. However, 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.When the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.Essen,Dry type transformer factoryOil immersed transformer companyThe plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety
