Abstract
The invention provides a wind power generation acceleration sensing method, which comprises a generator and a sensor, wherein a permanent acceleration vibration sensor is arranged on a wind generating set for permanent monitoring, the loss is minimized once the wind generating set is overhauled in the first time of abnormity, and the permanent acceleration vibration sensor is arranged on the wind generating set, so that the gear failure, gear abrasion, impeller vibration, electronic fault, unbalance, misalignment, looseness and resonance can be detected, and the service life of the wind generating set can be effectively prolonged.
Description
Technical field
The present invention relates to a kind of method of the acceleration sensing that generates electricity, especially a kind of method of wind power generation acceleration sensing.
Background technique
Generating is one of world today's important need, can generator set proper functioning be the main problem of paying close attention to, concerning wind power generating set, main bearing, gear-box and generator failure cannot be accepted, the replacement of these parts will be very expensive, and weight is big, the infield is on the high-altitude of 50-100 rice, the fan that wind power generating set and slowspeed machine drive, for example cooling tower, a lot of something in common are arranged, wind power generating set is a large-sized low-speed fan basically, but it is not the electric energy driving, mechanical energy is driven the large-sized low-speed fan by speed reducer, opposite, it provides mechanical energy, drives generator by accelerating chamber and produces electric energy, and this reverse process has the vibrative rotary component of a lot of meetings, loss may cause ultimate failure for a long time, maintenance expenses is very high, impossible working depth, and the loss of electric energy is very expensive.
Summary of the invention
The present invention is directed to the defective of prior art, a kind of method of wind power generation acceleration sensing of practicability is provided.
To achieve these goals, the present invention takes following measure to realize:
A kind of method of wind power generation acceleration sensing comprises generator, and sensor is characterized in that installing pemanent type acceleration vibration transducer and adds on wind power generating set, with permanent monitoring, in case there is the unusual very first time to give maintenance, loss is dropped to minimum.
The present invention has following progressive effect with respect to prior art: pemanent type acceleration vibration transducer is installed on wind power generating set, can measuring gear inefficacy, gear wear, bladed disk vibration, electronic failure, imbalance, misalign, become flexible, resonate, and can effectively prolong its life-span.
Embodiment
The speed of main bearing and rotating shaft approximately is 30-60rpm, this also is the rotational speed of gearbox input shaft, the speed scope is that the situation of 30-60cpm (0.5-1.0 hertz) should adopt low frequency acceleration vibration transducer, the scope of measuring comprises rotation frequency of spindle, blade passing frequency, the main bearing frequency, gearbox input shaft bearing frequency and gear mesh frequency or the like.These low frequency acceleration vibration transducers can provide 500mV/g and 12-180000cpm the frequency range of (0.2-3000 hertz) usually.
The jack shaft of gear-box and output shaft all can have than higher rotational speed, and produce than bearing and the higher forcing frequency of gear engagement, in fact, the speed of output shaft under normal conditions than the high 50-60 of input shaft doubly, measure the gear-box of its drive and the high rotation speed of generator set and need use universal acceleration vibration transducer, universal acceleration vibration transducer can provide the frequency range of 100mV/g and 30-900000cpm (0.5-15000 hertz).
Wind power generating set is usually on very high tower, its swivel assembly is difficult to approaching, therefore preferably uses bolt that the acceleration vibration transducer is installed, and mounting plane is main bearing for example, gear-box and generator etc. all need to process spot face, change hole and tapping so that vibration transducer is installed.
Wind power generating set need use reliable IP66 joint, prevent dust, entering of water or oil, military EQUAL joint of A2A or B2A sealed type joint can provide reliable connection to vibration transducer, Teflon overcoat cable or polyurethane cable and joint are used, and can connect for vibration transducer provides completely.
In the reality, the present invention is applied in the wind-power electricity generation, has reduced the wind power plant maintenance cost.
Claims (2)
1. the method for a wind power generation acceleration sensing comprises generator, sensor, it is characterized in that installing on wind power generating set pemanent type acceleration vibration transducer adds, with permanent monitoring,, loss is dropped to minimum in case there is the unusual very first time to give maintenance.
2. according to claim 1, it is characterized in that using bolt that the acceleration vibration transducer is installed, mounting plane is main bearing for example, and gear-box and generator etc. all needs to process spot face, changes hole and tapping so that vibration transducer is installed.
