PROJECT PRESENTATION ON ELECTRICITY GENERATION FROM SPEED BREAKER
GENERATION FROM SPEED.pptx (Size: 1.15 MB / Downloads: 110)
Introduction
A large amount of energy is wasted at the speed breakers through the dissipation of heat and also through friction.
When vehicle passes over speed breaker. There is great possibility of tapping this energy and generating power.
We can do it by making the speed-breaker as a power generation unit.
The generated power can be used for the power the street lamps, near the speed breakers
UTILISATION OF THIS WASTED ENERGY
Wasted power=Work done/Sec= (2452.5 x 0.10)/60
=4.0875 Watts (For One pushing force)
Power developed for 1 vehicle passing over the speed breaker arrangement for one minute= 4.0875 watts
Power developed for 60 minutes (1 hr)=245.25watts.
Power developed for 24 hours = 5.866 Kw
This power is sufficient to burn four street lights in the roads in the night time & also for nearby shops.
BASIC PRINCIPLE-
The project is concerned with generation of electricity from speed breakers-like set up. The load acted upon the speed breaker - setup is there by transmitted to rack and pinion arrangements .
Here the reciprocating motion of the speed-breaker is converted into rotary motion using the rack and pinion arrangement.
The axis of the pinion is coupled with the sprocket arrangement. The sprocket arrangement is made of two sprockets. One of larger size and the other of smaller size. Both the sprockets are connected by means of a chain which serves in transmitting power from the larger sprocket to the smaller sprocket.
As the power is transmitted from the larger sprocket to the smaller sprocket, the speed that is available at the larger sprocket is relatively multiplied at the rotation of the smaller sprocket.
SPECIFICATIONS OF DC GENERATOR
443541 Permanent Magnet DC Generator
Current Rating for the # 443541
3 A - Continuous Duty
3.3 A - 60 minutes
4 A - 30 minutes
10 A - 5 minutes
Magnets: Two high-energy saturated C8 ceramic magnets.
Shaft: Steel 12.7mm (1/2") diameter, 40mm length, with 1mm full-length flat.
Armature: 16-slot armature 52mm diameter wound with AWG25 magnet wire
Bearings: Two double-sealed 32mm OD ball bearings.
Rotation: Either direction - The red output wire is positive for clockwise rotation from the shaft end.
Speed: Zero to 5,000 rpm - generates at all speeds- depends on load.
Weight: 4.2Kg (9.2lb) Shipping weight 4.6Kg (10lb), dimensions 150x150x300mm (6x6x12in).
Resistance: Internal resistance 7.7 ohms. Inductance 16mH.
Maximum charging current is 10A If you exceed these specifications the generator will overheat
Rough estimation of profit
The total installation cost of the hump is 7000 rupees.
Total cost = 7000 rupees
Say with improvements in design it can glow 5 streetlights of 40-watt capacity,
which will consume 2.7 K.W.H. per day.
For t years electricity bill will be 3449.25*t
T=2years
i.e. the consumer will be repaid his investment with in 2 years period. From this
onwards, there will be no investment and free of cost. The life of POWER HUMP is estimated to be 7 years. So the customer will get free power generation for 5 years period.
This power comes from the energy which is wasted on roads.
