When the transformer is out of phase
Oil leakage at looper flange
Power transformer factory
HoffThe insulation between silicon steel sheets is damaged， if the second phase is blocked， there is still no sound when the second phase is sent， and there is sound when the third phase is sent; If the third phase is blocked， the sound will not change， as in the case of the second phase. There are three reasons for phase deficiency:
BiskAvoid the load operation of power transformer: if the load operation is long-term， it will lead to the scalding of solenoid coil， short circuit fault between boxes， two-color short circuit fault or short circuit to ground fault and dissolution of oil.
After sampling， bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.
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.
Under normal conditions， the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation， the operation and maintenance management staff shall improve the safety inspection range of the transformer， and immediately communicate and contact with the on-site project staff in case of any problems， so as to ensure the reliable and stable operation of machinery and equipment.
According to statistics， to occupy the main global technical position， the transformer industry depends on two key data commodity volume and voltage level. As early as & ldquo; Eleventh Five Year Plan; In the early stage， China has been a powerful country in the production， manufacturing and application of dry-type transformers all over the world， but it is not a big country.
The time difference between different steps of three-phase power switch of switching power supply shall be less than ms， the closing shall be maintained by high-voltage arrester， and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).
Where to sell APIHow to reduce the failure of dry-type transformer?
It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials， laminated glass and other materials very well， so as to achieve the pressure management of oil leakage.
Dry type transformer factory
What is the wavelength of oil immersed transformer?
whereDry 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 .%，HoffOutdoor energy-saving oil immersed transformer， and then reduce the building structure noise transmitted by dry-type transformer oscillation.
The cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions generally from half a year to once a year;
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.
HoffThe cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of -A / Min.
In specific daily life， oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact， the wave height of oil immersed transformer also shows the size of kinetic energy. Generally，HoffPrice of box transformer 1600， the greater the output power is. On the contrary， it is very small.
In the case of dry-type transformer operation，HoffTransformer Daquan， there is more noise， and some even cause noise， which seriously endangers everyone"s no problem rest time and work. At this time， the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer"s network editor to simply understand it.
