PatanOld box tIf the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire,Caracole10kV oil immersed distribution transformer, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.
Noise dispersion of dry-type transformer
Caracole.The iron loss of transformer includes two levels. The first is the hysteresis loss introduced by the transformer manufacturer. When the AC circuit is based on the transformer, according to the magnetic induction line of the transformer ferrite core,CaracoleApplication of oil immersed transformer, its orientation and size change with the change,CaracoleWhich is a good oil immersed test transformer, which promotes the internal molecular structure of the ferrite core to interact with each other, releases energy, and then loses part of electromagnetic energy, which is the hysteresis loss. The other is the vortex loss when the transformer is working.
The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;
The voltage regulating tap changer is not in place or poor
When the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.
After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.
Protection mode for type selection of dry-type test transformer
The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.
Where is good.Dry type transformer factory
The time difference between different steps of three-phase power switch of switching power supply shall be less than 10ms, the closing shall be maintained by high-voltage arrester, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).
Method and process of taking oil sample of power transformer
How much is the power transformer
High quality and low price.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.
It should be said that after the development trend of these years the overall level of China's transformer industry at this stage is basically international, and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.
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.
Caracole.Before no-load impulse closing, the transformer shall be placed for 24h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.
Caused by sand holes and cracks. For crack leakage, dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; There is likely to be oil or leakage after fire, and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;
