Power transformerDry type transformerUtrecht,Power saving analysis of transformerThe scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?Nyiregyhaza,Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, and long-term scalding of iron core will lead to insulation aging.Brief introduction of zero line of power transformerThe zero line is mainly used in the working circuit. The voltage caused by the zero line is equivalent to the line resistance multiplied by the current of the working circuit. Because of the distance,UtrechtApplication of dry type transformer, the voltage caused by the zero line can not be ignored. As a countermeasure to maintain life safety, it is more and more unreliable. Ground wire (PE): it is not used as a working circuit, but only as a maintenance line. Use the affirmation of the earth & ldquo; ” Voltage. When the machine and equipment casing is electrified, the current will be quickly grounded. Even if there is a lead for the PE line,Utrecht2000 dry type transformer manufacturer, it will be grounded from the surrounding grounding body.

When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency: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, 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.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, so as to achieve the pressure management of oil leakage.Direct material,When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, and loosen your thumb to make the oil enter the pipe,Operation and maintenance management of oil immersed transformerPlug 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,UtrechtWorking principle of power transformer, please cut off the input switching power supply.

Dry type transformer factoryreform,Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).In order to promote the use of energy-saving transformers, the Ministry of finance, the Ministry of industry and information technology and the national development and Reform Commission jointly promulgated the detailed rules for the implementation of energy-saving distribution transformers of energy-saving products benefiting the people project as early as , providing subsidies of - yuan / KVA for energy-saving transformers.Oil leakage of bolt or pipe external threadUtrecht,Causes of fire in power transformerA specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?Turn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank, so as to reduce the working pressure and leakage. After the leakage location is determined appropriate surface treatment shall be carried out, and then Fushi blue raw materials shall be selected for sealing treatment.
