Oil immersed transformer operation
New zamkiThe 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.
According to the condition of cracks， galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.
PaidaUse 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，New zamkiHow much is the European box transformer， and then tighten it after wiping the raw materials on the surface. After drying， the treatment goal can be achieved.
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.

Noise pollution control and prevention measures of dry-type transformer
The visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find the abnormal conditions of the equipment， such as discoloration， deformation， offset， cracking loosening， ignition smoke， oil leakage， broken strand disconnection， short-circuit fault marks， hanging of dirty things， etching and turbidity， which can be inspected according to the visual inspection method. Therefore， pay attention to the following matters:
discountThe insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.
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，New zamkiTransformer power transmission and ignition， the treatment goal can be achieved.

Protection mode for type selection of dry-type test transformer
The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation， maintenance and transportation， and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.
New zamkiIn specific daily life，New zamkiThe dry-type transformer is good， oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact， the wave height of oil immersed transformer also shows the size of kinetic energy. Generally， computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is， the greater the output power is. On the contrary， it is very small.
High voltage fuse of transformer breaks one phase;
& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by V megger， the resistance value exceeds m ohm bus.
