SeinyokiPrice of 1250kva dry type transformerProfession is king

which can avoid the entry of solid dirt with a diameter of more than 12mm, rats, snakes, cats, birds and other animals, resulting in vicious common faults such as short-circuit fault and power failure, and provide a safe natural barrier for the energized part. If the transformer equipment must be outdoors, IP23 protective casing can be adopted, which can avoid being equally divided with the above IP20 protective effects However,SeinyokiTransformer box, so pay attention to the reduction of its operating volume.

Therefore, in the installation process of substation equipment, the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition, in the installation and use process of lightning rod select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition, during the installation of lightning rod, please connect all routes as far as possible to prevent other faults.

.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.

A 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?

After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.

The dry-type transformer used for power plant voltage transformation is different from the oil transformer. It is strictly prohibited to lead the way at the bottom voltage side to prevent the insulation layer of the dry-type transformer from penetrating due to overvoltage caused by overvoltage at the power grid side or lightning stroke on the line.

Wiring mode of dry-type transformer:

Quality management.The no-load impulse closing working voltage shall not exceed 5% of the working voltage marked on the gear of the transformer, the closing frequency shall be 5 times, the delay time after power receiving shall not be less than 10min, and the time interval of each closing shall not be less than 5min.

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.

When the transformer is put into operation, if the tap changer is not in time, a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective, it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound, once the load increases, it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.

Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side,Seinyoki1600 oil immersed transformer, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited, the generator set must be disassembled first.

The cheapest.The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat, temperature rise,SeinyokiThe power supply of the transformer is, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, and the historical time Zui high temperature can be recorded). The Zui high temperature can be input and output as 420mA analog quantity. If it is to be far away (the distance can reach 1200m, the electronic computer can be equipped with an electronic computer socket, an intelligent transmitter, and 31 transformers can be detected. The over temperature alarm and trip of the system software can also be signaled by the resistor data of Pt100 thermistor sensor, so as to further improve the stability of the temperature maintenance system software.

Caused by sand holes and cracks. For crack leakage drilling stop hole is a good way to remove in-situ stress and prevent widening.

Seinyoki.How to reduce the failure of dry-type transformer?

After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.
