Parts and Accessories:
Hummer wind turbine includes the body, tower plus accessories, and controlling units.
Body includes: rotor blades, generator, yaw shaft, nose cone, tail pole, tail wing, etc.
Tower and accessory: pole, nut, pedestal, guy wire, anchor, and cable, etc.
controlling unit: controller ,inverter and load dumping. The generator, blades, nose cone,
shaft, tail pole, tail wing, tower, anchor, etc are all spray-painted, galvanized and antisepticised.
Generator:
This generator is the most advanced in the world, which has four patents.
It is extremely light and small, high in efficiency--more than 0.78 of utilization ratio.
Light: Generator is extremely light. Eg; The weight of 1000w generator is only 15kg, including blades, hub and nose cone.
Small: The generator is inside the nose cone, and the volume is only 1/6 of conventional ones.
Low in energy consumption, noise and speed-up wind speed (3m/s for 1000W).
Swift running: hummer generator runs 1.5 - 3 times faster than other types of generators under equal conditions due to lightness, high efficiency and low resistance. As a result it can output more power than others.
Swift charging: due to high efficiency and low wind start-up, the running time of hummer generator will be longer than conventional ones, and that is why it can charge batteries faster than others.
Hybrid Off-grid Controller/Inverter:
Control System:
● The power efficiency has been highly improved by using IGBT.
● With the automatic program optimization of MPPT the generator capacity is highly improved.
● LCD indicates information simultaneously.
● Real-time working power curve can be seen from the PC interface.
● Several optional communication interface includes power line carrier, RS485, wireless data transmission.
● Comprehensive protection function with highly reliability
● Wide AC voltage range
● Freely set working curve chart
● Simple, reliable and special plug connection
Rotor blade:
Blades can typically be made of glass fiber reinforced plastic or aluminum alloy.
The Hummer blade is designed by aerodynamic experts according to the air-screw structure and the wind power utilization ratio enhances up to 0.78.
Most turbine blades have weak endurance through gale force type winds, they break easily in low temperature, the usable time in gale area is usually no more than 3 years, etc, Hummer has designed a new wind turbine blade, which can bear gale force winds.
The hummer wind blade's successful application prolongs the entire wind turbine's service life to 10-15 years more. With the auto-deflection tech, it operates stable-quietly and soundlessly, and also brings enormous convenience for use and replacement.
Nose cone:
The nose cone is made of reinforced aluminum alloy.
It's located in front of blades to reduce the wind resistance. The generator is enclosed in the nose cone, which is favorable for heat dispersion.
Protection cover:
It is located between the blades and nose cone, and is made of reinforced aluminum alloy to further reduce the wind resistance and protect the generator.
Yaw shaft:
It is made of superior steel to integrate blades, the generator, tail pole, tail wing and tower. Inside the yaw shaft there are slip rings to prevent the cable from twisting.
Tail pole:
It is light with high intensity and made of manganese steel.
Tail wing:
It is made of stainless steel, inflexible, auto-deflection in high wind condition, reliable and sharp in speed limitation.
Tower:
It is made of carbon steel, with several sizes of outer diameter and height. They are anti-corrosion, as well as UV-proof.
Guy wires & anchors:
Guy wire adopts button structure, and arrow like anchor, so it is much easier for installation
Surface coating & protection:
All the parts are static molded and then galvanized, so they are anti-corrosion, UV-proof, crash-worthy, fastness and will be fresh all year round.
All the parts are made of high quality aluminum alloy and superior steel, which can be used in the temperature ranging
from -45℃ to 45℃, in the surroundings of highly wet, sand salt or frost area.
