`IBRICharacterFor 630kVA power engineering transformer, plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.
& ldquo; YN, D11 & rdquo;, in which 11 indicates that when the working voltage phasor of the primary side line, as the minute hand,Cautta Model of control transformer, refers to the position at 12 o'clock, the phase voltage phasor of the secondary side is at 11 o'clock. That is, the phase voltage UAB of the secondary side lags 30 degrees behind the working voltage uab330 of the primary side line (or 30 degrees ahead).
Cautta .The insulation of the through core anchor bolt clamping the iron core is damaged, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;
Dry type transformer
.Oil leakage at looper flange
Noise solution of dry-type transformer
Before no-load impact closing, the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.
Noise pollution control and prevention measures of dry-type transformer
In fact, apart from the application of the Finance Bureau,Cautta Dry type transformer technology, the industry has been trying to formulate and upgrade transformer commodities according to the specifications so as to promote the improvement of energy consumption level of transformer commodities.
Power transformer plant
retailer.The oil in the machinery and equipment of the oil storage tank shall generally stand for more than 8h before sampling; it is not necessary to stand when sampling on the running power transformer.
The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.
Power transformers are used in all walks of life
If the above provisions are not met, the problem of dryness shall be solved. Generally,Cautta Price of dry-type transformer shell, it is OK to operate the centrifugal fan for a period of time. Check the cleanliness of the power transformer. If too much dust is found, it must be eliminated to ensure indoor ventilation and avoid insulation penetration. In particular, pay attention to cleaning the insulators of the power transformer and the top and bottom ends of winding resistance installation. Portable centrifugal fan or dry air compression or N2 shall be used to clean the dust in indoor space that is not easy to reach, such as ventilation duct, and there shall be no dirt.
market.For example, in the 1970s, and then lead a point of it out of the road with transmission line and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, office and other electrical equipment.
Several detection methods for installing transformer
Due to poor sealing, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.
Cautta .Solenoid insulation deterioration
Oil immersed transformer operation
If 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, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.
