Seal oil leakage
Baladro.The equipment can eliminate the shortcomings found in the patrol inspection, remove and replace the cracked or brittle leather pad, check and tighten the node, replenish the oil with less oil, check and replace the silica gel of the breathing mask, etc.
The noise of dry-type transformer belongs to low-frequency noise. In a small area, which is then scattered to the ears of consumers. Although the amount of noise is not very large and then causes gas vibration noise, the dispersion spacing and adverse effects are very large.
.In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.
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.
For the leakage that has already occurred,BaladroDistribution transformer maintenance, 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.
If you want to check the activated carbon fiber for the hanging cover, first take out the low-voltage waterproof sleeve and the on load transformer power switch, then lower the bell cover anchor bolt of the large cover, slowly hang the galvanized steel wire rope with sufficient lifting net weight on the commonly used earrings, wear 4 round steel from top to bottom in the surrounding screw holes, and count the spacing and specifications for easy reinstallation. At the same time, the cable wind shall be added on all sides to ensure that the core international body will not be damaged during the whole lifting process. After lifting for 100mm, stabilize the bell cover, and check the bearing capacity of the lifting core, center of gravity and Jack. After everything is normal,BaladroOil immersed transformer bidding, lift it again until the bell cover exceeds the relative height of the body, and rotate the crane to place the bell cover on the clean skid.
At that time, only a few companies in China could produce 500kV high-voltage transformers,BaladroKs11 mining power transformer, and the market share of high-voltage transformers was basically monopolized by overseas leaders.
In specific daily life, 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, 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.
The top and middle of the transformer oil tank it is very small.
build.The switching power supply lacks one phase of power;
Oil leakage at electric welding position
The voltage regulating tap changer is not in place or poor

Supply chain quality management.When leaving the factory, the flange plate, barrel skin and the middle of the waterproof sleeve at the upper end of the automobile oil tank. The internal iron core and winding clamp are hot due to partial magnetic leakage, resulting in insulation damage.
For example, in the 1970s, 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, office and other electrical equipment.
Baladro.When the whole process of winding wave of oil immersed transformer is calculated by using the marking method, the winding of oil immersed transformer is generally divided into multiple modules, and each module is replaced by an equivalent circuit, and its power circuit includes an inductance and vertical capacitance, a capacitance to ground or capacitance between windings, They also have mutual inductors between the inductors of each module, and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.
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.
Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;
