Rostov is in tgenerally, 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.
In terms of the place of use, 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;
Kanatir Kariye.During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.
Oil leakage of heat pipe radiator
.When sampling in bulk gasoline barrels, samples shall be selected according to 5% of the number of gasoline barrels, but not less than 2 barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to 2% of the total number of barrels (bottles).
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.
Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, commerce, airports, tunnel construction, chemical enterprises and factories.
Fault judgment of power transformer
Oil sample inspection & mdash; & mdash; the performance parameters such as compression resistance and residue shall be carried out every three years. The long-term overload or overload of the transformer can reduce the cycle time.
Dry type transformer manufacturer
Executive standard.Power transformers are used in all walks of life
Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.
The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance, capacitance and resistor. The accuracy of those basic parameters does great harm to the calculation results of the whole wave process. For the inductance calculation, the good model is the solid model of infinite transformer core column, but there are many calculation methods.
Before no-load impulse closing,Kanatir KariyeOperation and maintenance of dry type transformer, the transformer shall be placed for 24h,Kanatir KariyeMain transformer of power plant, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.
property right.The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?
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.
Oil leakage of porcelain pot and laminated glass oil level gauge
Kanatir Kariye.The heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding, oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.
How to reduce the failure of dry-type transformer?
The voltage regulating tap changer is not in place or poor
