Old horsePrice of 2000kVA dry type transformerWhat causes abnormal machining accuracy failure

Power transformer factoryWhat is the wavelength of oil immersed transformer?Old horse,The transformer manufacturer said that the temperature display equipment: the temperature change value is measured according to the PT temperature sensor embedded in the bottom voltage winding to immediately indicate the winding temperature of each phase (three-phase safety inspection and Zui large value indication, and the historical time Zui high temperature can be recorded). The Zui high temperature can be input and output as mA analog quantity. If it is to be far away (the distance can reach m, the electronic computer can be equipped with an electronic computer socket, an intelligent transmitter, and transformers can be detected. The over temperature alarm and trip of the system software can also be signaled by the resistor data of Pt thermistor sensor, so as to further improve the stability of the temperature maintenance system software.When leaving the factory, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.CantoraFor example, in the s, the radio programs applied by every family in the countryside had a ground wire, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances office and other electrical equipment.During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.Before no-load impulse closing, the transformer shall be placed for h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.

Power transformers are used in all walks of lifePower transformer is indispensable for power stations and substations,Old horseDry type transformer temperature standard, but we must pay attention to many problems in the whole process of applying power transformer.Wiring mode of dry-type transformer:DiscountWhat is the important role of power transformerWhen 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.For the leakage that has already occurred, find the leakage point first, which can not be ignored. For the position with serious leakage, shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation, the goal of long-term treatment of leakage can be achieved.

Use 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.Test method, the transformer was disconnected by vibration (but there was no grounding device).The rate of transformer is: n = P / pxo%, that is, 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.What is the important role of power transformerOld horse,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,Old horsePrice of 200KVA transformer, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.If the volume of power transformer is too small,Old horseWorking principle of power transformer, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore, causing short circuit obstruction. If not handled properly, it will cause great damage.
