GaochengWhat are the oil immersed transformer protectionsHigh quality and low price

Then clamp the branch pipe with your thumb clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.Wiring mode of dry-type transformer:Gaocheng,Transformer inspection earIf 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,GaochengGrid 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.El Monte,The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings, because the electric field between the winding and the iron yoke is far away and not as symmetrical as that between the windings. In the electric field in the middle of the winding, most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding, that is, the disconnection component of the electric field is small.Gradually, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer, which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings, roads, etc. with flexible connection, or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible, the dry-type transformer room can also be soundproofed and decorated, 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.According to statistics,GaochengPrice of 2000 KVA dry type transformer, to occupy the main global technical position, the transformer industry depends on two key data, commodity volume and voltage level. As early as & ldquo; Eleventh Five Year Plan; In the early stage, China has been a powerful country in the production, manufacturing and application of dry-type transformers all over the world, but it is not a big country.& ldquo; YN, D & rdquo; in which indicates that when the working voltage phasor of the primary side line, as the minute hand, refers to the position at o'clock the phase voltage phasor of the secondary side is at o'clock. That is, the phase voltage UAB of the secondary side lags degrees behind the working voltage uab of the primary side line (or degrees ahead).quality standard,In the whole process of transmitting electromagnetic energy in the power supply system, it will inevitably cause the loss of voltage and output power. When transporting the same output power, the voltage loss is inversely proportional to the voltage, and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.(III) dry type transformers of KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than m; The distance between the electrified part and the road surface shall not be less than m.Oil leakage of heat pipe radiator

Note: in the whole process of safety patrol inspection, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary,(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than m; At the angle with actual operation, a spacing of more than m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.The proper selection of Anhui dry-type transformer has a key effect on improving the safety and smooth operation of power system software. In the above original text, we will describe how to select dry-type transformer according to the load characteristics and application environment of dry-type transformer.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,Gaocheng and loosen your thumb to make the oil enter the pipe,In the whole process of transmitting electromagnetic energy in the power supply system, it will inevitably cause the loss of voltage and output power. When transporting the same output power,GaochengWhat qualifications are required to install power transformers, the voltage loss is inversely proportional to the voltage, and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, it is very easy to cause fire accidents, power failure, damage to machinery and equipment, etc.The oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.
