ColumbiaPower transformer energy consumption standardHow to deal with the local deformation of

Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited, the generator set must be disassembled first.

When the new oil filled by the power transformer and the oil sample that has just been considered are used,ColumbiaBox type transformer room, the oil sample can be used only after sufficient standing.

Columbia.The 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.

The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.

.In the case of dry-type transformer operation, there is more noise, and some even cause noise, which seriously endangers everyone's no problem rest time and work. At this time,ColumbiaPrice of oil immersed transformer, 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.

In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?

There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let's master and consult in detail with the small editor of the dry-type transformer manufacturer.

Falling foreign matters and piercing

Overtemperature alarm and trip: collect winding or iron core temperature data signals according to the temperature measurement resistor of PTC discrete system thermistor embedded in the bottom voltage winding. When the transformer winding temperature rises again, if it reaches 155 ℃, the system software outputs the overtemperature alarm system; If the temperature rises to 170 ℃ again and the transformer can no longer operate the overtemperature trip data signal must be transported to the secondary maintenance circuit, and the transformer shall be tripped quickly.

What is the wiring mode of dry-type transformer?

Oil leakage of porcelain pot and laminated glass oil level gauge

The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, although dry-type transformer has strong moisture resistance, it is generally open structure or very susceptible to moisture,Columbia1600KVA price of power transformer, especially the insulation level of dry-type transformer manufactured in China is low (lower flame retardant grade) Therefore, the dry-type transformer can obtain high stability only when the air humidity is below 70%. The dry-type transformer shall also be prevented from stopping operation for a long time to prevent serious damp. When the grounding resistance value is less than 1000 / V (operating voltage), it indicates that the transformer is seriously damp, and the trial operation shall be terminated.

The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand the fixed finger is at 12 o'clock, and the waist rail shall be & phi; 0mm galvanized wire shall be wound over 4 turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than 0.2m.

During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.
