The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.
Ovregon.Step up process of dry-type transformer?
High voltage fuse of transformer breaks one phase;
.Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below 0.2%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.

Manufacturing process and steps of dry-type transformer
When using the oil sample of the power transformer in operation, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about 2kg of waste liquid stored at the bottom to clean the oil inlet, and then take the oil sample.
With Vietnam and Malaysia China's first UHV transmission experimental demonstration project, China Transformer Corporation has entered a breakthrough in the development trend. The commodity voltage grade and volume rank first in the world, occupying the main technical position of the industry development trend. In addition, it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.
Oil leakage of cast iron parts
Energy costs.The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below 2000kVA and the working voltage is below 35KV, which also ensures the rated voltage of 110kV; Oil immersed transformers are generally suitable for distribution equipment.
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).
Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window, ventilation and air exchange port and road surface,Ovregon10kV transformer oil immersed, and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.

Inspection requirements.Brief introduction of zero line of power transformer
For oil transformer oil replenishment,OvregonWithstand voltage of 10kV oil immersed transformer, the oil with the same basic, same brand and same additive type is expected to have a stronger effect. The characteristics of the oil should not be lower than that of the oil in mechanical equipment. When the new remaining oil is less than 5%, if there is more new remaining oil, oil shall be added before oil type Chromatographic analysis and pressure test shall be carried out to establish that there is no oil stain,Ovregon630 oil immersed transformer, and the acid value and dielectric loss shall not exceed the oil in the machinery and equipment.
The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ 4Ω, The resistor is generally more than 2000 & omega;, According to Ohm's law, when the insulating layer is damaged, the current is only 1 / 500 of the total current flow, so as to play a guarantee effect. The higher the voltage, in other words in the case of high voltage. We can care about the power transformer plant and master a lot of professional knowledge.
Ovregon.(III) dry type transformers of 315KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than 5m; The distance between the electrified part and the road surface shall not be less than 5m.
In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, it will affect the whole power circuit
