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 .%， and then reduce the building structure noise transmitted by dry-type transformer oscillation.
The hanging core of dry-type transformer is a vital part
Madinat HamadHow is the quality level of dry-type transformer compared with foreign countries?
The whole process of hanging the core of dry-type transformer is more critical， and there are many situations that the hanging core of dry-type transformer must pay special attention to. Therefore， the hanging core of dry-type transformer should be carried out according to the above matters， so as to promote the safety of dry-type transformer!
LibrevilleOperation of oil immersed transformer
Before no-load impact closing，Madinat HamadComposition of dry-type power transformer， 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.
Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut)，Madinat HamadProcurement of dry type transformers， wipe the Fushi blue film remover on the surface， and then tighten it after wiping the raw materials on the surface. After drying， the treatment goal can be achieved.
kV and above & plusmn; No load of rated voltage; Part of the circuit breaker of the tap power switch is installed in the phenolic resin insulating paper cylinder， and the insulating paper cylinder is installed on the wooden frame. The actual operation rocker is connected with the dynamic circuit breaker of the tap power switch according to the wooden insulating rod. The on load tap off power switch is insulated from the ground by the insulating paper cylinder of the power switch itself and the insulating limit.
Automatic system of centrifugal fan: measure the temperature data signal according to the PT thermistor temperature measuring resistor of the embedded parts at the hot part of the bottom pressure winding. The transformer load expands and the operating temperature increases. When the winding temperature reaches ℃， the system software automatically starts the centrifugal fan for refrigeration; When the winding temperature is as low as ℃， the system software will automatically terminate the centrifugal fan.
After the test， connect the data signal contact of the automobile relay with the alarm circuit the pull-in contact with the opening circuit， and adjust the overcurrent protection value.
market priceThe capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below kVA and the working voltage is below KV， which also ensures the rated voltage of kV; Oil immersed transformers are generally suitable for distribution equipment.
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 kg of waste liquid stored at the bottom to clean the oil inlet， and then take the oil sample.

Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut)， wipe the Fushi blue film remover on the surface， and then tighten it after wiping the raw materials on the surface. After drying，Madinat HamadOperation and maintenance of dry type transformer， the treatment goal can be achieved.
DiscountIn 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;
This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.
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.
Madinat HamadThe scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?
Different diversion methods
