Difference between dry-type transformer and oil immersed transformer:
If 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， 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.
PrivizaThe transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment， such as transformer in operation and neutral grounding equipment of arc suppression coil. For the equipment without power supply and whose shell is reliable grounding device， the temperature or temperature rise must be tested by hand. The secondary equipment can be inspected by hand touch method when it is hot and vibrated.

After the test， connect the data signal contact of the automobile relay with the alarm circuit， the pull-in contact with the opening circuit，PrivizaHow much is a 250kVA box transformer， and adjust the overcurrent protection value.
The zero line is mainly used in the working circuit. The voltage caused by the zero line is equivalent to the line resistance multiplied by the current of the working circuit. Because of the distance，PrivizaInstallation requirements for indoor oil immersed transformer， it is more and more unreliable. Ground wire (PE): it is not used as a working circuit， but only as a maintenance line. Use the affirmation of the earth & ldquo; ” Voltage. When the machine and equipment casing is electrified， the current will be quickly grounded. Even if there is a lead for the PE line it will be grounded from the surrounding grounding body.
Under normal conditions， and immediately communicate and contact with the on-site project staff in case of any problems the operation and maintenance management staff shall improve the safety inspection range of the transformer， so as to ensure the reliable and stable operation of machinery and equipment.
Right， as & ldquo; Great Lars car & rdquo;， After replacing one kva small transformer， the utilization rate is close， but the main parameters of the two transformers are evaluated as shown in Table . Table evaluates the main parameters of the transformer: capacity (VA) iron loss (W) copper loss (W). Firstly， the output power is saved according to the customary calculation method (ignoring copper loss): the results show that the loss of large capacity transformer is lower than that of small capacity transformer， It actually consumes electromagnetic energy.
In the case of using dry-type transformer， customers must master the method of wiring. If there are problems in wiring， it is easy to cause common faults in application. So what is the wiring mode of dry-type transformer?
Direct laborSound， causing short circuit obstruction. If not handled properly， it will cause great damage.
When the manufacturer of the power transformer samples from the automobile oil tank， after opening the sealing cover，Priviza2000 KVA power transformer， use the cleaned and dried rubber stopper to the oil. At the same time， and loosen your thumb to make the oil enter the pipe，
The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer， and the vibration reduction solution is made at the cable bridge.
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.
Quality AssuranceThe vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer， and the vibration reduction solution is made at the cable bridge.

Overload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation， which dissolve and ignite， resulting in a lot of steam bodies， greatly increasing the internal working pressure of the power transformer， causing the ignition of the casing， causing large-scale power failure， endangering all normal production， manufacturing and activities. There are three reasons for fire accidents in the operation of power transformers.
