Webb Auction House, which is in charge of the auction, said that a feather of the long-extinct new Zealand gray butterfly bird (H) set a record price of 46521 new Zealand dollars (about 205874 yuan), making it the most expensive feather ever in the world.

H was last confirmed to be seen in the early 20th century, and its feathers previously sold for as much as 8400 new Zealand dollars (approximately 37173 yuan).

As a member of the wybird family, H was cherished by many and ultimately proved fatal to the species.

For Maori, the bird’s feathers are a symbol of lofty status, and its unique white feathers are used for ceremonial headdresses. Only those in the main ranks are allowed to wear H feathers on their hair, or entire skins on their ears, according to the new Zealand Museum.

The auction house said the feathers were often exchanged for other valuables or given as gifts to show friendship and respect.

European new Zealand people have also begun to regard H as a symbol of prestige. According to the museum, they use the animal’s feathers as fashion accessories and install padded H’s as decoration in wealthy homes.

The museum explained that in the 19th century, Maori and European hunters killed the bird in large numbers and sold its skin to collectors and fashion merchants.

According to reports, in 1901, the Duke and Duchess of York were photographed wearing H feathers in their hats while traveling in new Zealand, and the bird’s deadly popularity further increased.

People are a little crazy, everyone wants an H feather.

In the early 20th century, scientists tried to protect the remaining H, but failed. According to the museum, the government planned to transport the birds to offshore islands, but those who collected the birds sold them as dead specimens, adding that it was more valuable than keeping them alive.

The auction house said all potential buyers must provide a permit from the new Zealand Department of Culture and Heritage before Monday’s auction. As an important national item, feathers can only be purchased by registered collectors and cannot be exported without permission from the Ministry of Health. (Reporter Wang Yuehang)

　　The daily maintenance of marine diesel generator set is the key to ensure its stable operation. The following are some precautions for routine maintenance:Mentioned in the article boat generator Born with strong vitality, you can turn a cocoon into a butterfly and become the best yourself after wind and rain. https://usrpower.com/product/usr-pgm-marine-generator-jec60-6kva/

　　I. General Maintenance of Marine Diesel Generator Set

　　Clean environment:

　　Ensure that there is no water, oil, dirt and corrosive gas near the marine diesel generator set, so as not to damage the insulation of the generator winding.

　　Always clean the dust and dirt in the ventilation duct and keep it unobstructed to ensure the normal ventilation and cooling of the generator.

　　Moisture and dust prevention:

　　Prevent the temperature of cooling air from being too low, so as to avoid condensation of water droplets on windings and other conductive devices.

　　While preventing moisture and dust, be careful not to affect the normal ventilation and cooling of the generator.

　　Rust prevention treatment:

　　If the machined surface of marine diesel generator sets is rusted due to paint peeling, it should be derusted in time and coated with antirust paint.

　　Second, the marine diesel generator set disassembly and inspection

　　Precautions for disassembly:

　　The disassembly and assembly method of marine diesel generator set is basically the same as that of asynchronous motor, but due to the heavy weight of generator, attention should be paid to avoid collision during disassembly and assembly.

　　When removing the end cover, be careful not to damage the stator coil protruding from the base; When taking out the rotor, put cardboard between the stator and rotor of the motor to prevent damage to the core and winding.

　　When binding the rotor with steel cable, the steel cable shall not touch the rotor journal, slip ring and transfer lead.

　　Regular inspection:

　　Check the inside of the generator carefully to ensure that there are no sundries and prevent them from falling into foreign bodies such as screws, tools and rags.

　　Check the lubrication of generator bearings, and the quality and quantity of lubricating oil and grease should meet the requirements of maintenance.

　　Check whether the connection between marine diesel generator set and its prime mover is good, and check whether the axes of the two engines are on the same straight line.

　　Check whether the rotor is flexible and the bearing quality.

　　Iii. Insulation and Drying of Marine Diesel Generator Sets

　　Insulation resistance measurement:

　　Measure the insulation resistance of the generator every three months, including stator and rotor.

　　In order to prevent the measured voltage from damaging the rectifier or other semiconductor equipment, the anode and cathode of the rectifier diode should be temporarily shorted, and the terminal of the electronic circuit board (such as AVR board) should be temporarily removed.

　　Use a 500V megohmmeter to measure the insulation resistance, which should be no less than 0.5MΩ.

　　Generator drying:

　　Newly installed synchronous generators should generally be dried before operation.

　　If the insulation resistance meets the requirements, drying is not required.

　　When the generator in operation is stopped for maintenance or stopped for more than the specified limit, and the insulation resistance is lower than the specified value, it must be dried.

　　Drying methods include hot air method, short-circuit current drying method and loading drying method.

　　Four, marine diesel generator operation monitoring

　　Temperature monitoring:

　　Monitor the temperature of each part of marine diesel generator set, including generator temperature rise and bearing temperature.

　　Excessive generator temperature will accelerate the aging of insulation materials and shorten the service life of generators.

　　For generators in the form of sliding bearings, the allowable bearing temperature is 70≧; For generators in the form of rolling bearings, the allowable bearing temperature is 80≧.

　　Voltage and power factor monitoring:

　　The generator voltage in operation should reach the rated value.

　　Monitor power factor and grid frequency to ensure normal operation of alternator.

　　To sum up, the daily maintenance of marine diesel generator sets involves many aspects, including general maintenance, disassembly and inspection, insulation and drying, and operation monitoring. By carrying out these maintenance work regularly, the stable operation of the generator set can be ensured and the service time can be prolonged.
