Abstract
The utility model relates to a failure detection device, in particular to a failure detection device of a 2.5MW wind gear box running in severe conditions for a long time. The failure detection device comprises a vibrating sensor arranged on a high speed shaft and a low speed shaft, wherein the vibrating sensor is connected with a state monitoring box which is connected with a low voltage control cabinet through Ethernet cables; the low voltage control cabinet sends the signals to a tower bottom control cabinet through optical fibers; and the tower bottom control cabinet transmits the signals to a control room PC terminal through the network at a wind field. The device has the advantages of being capable of accurately finding the failure position and failure point, shortening the wind turbine stop time caused by repairing the gear box and finding and treating the problems in time.

Technical field
The utility model relates to a kind of failure detector, relates in particular to a kind of failure detector that is in the 2.5MW wind-powered electricity generation gear case of operation under some mal-condition for a long time.
Background technology
China's wind energy turbine set majority is in mountain area with a varied topography or hilly country, as the gear case of transferring power, because the instability of air-flow causes gear case to be in for a long time under the complicated alternate load and works.Because equipment is installed in tens meters high-altitudes, deliver to factory repair to the inconvenience dismounting, and can not in time pinpoint the problems fault detect, bring potential safety hazard may for like this operation of equipment.From the fault that wind-driven generator group wheel box takes place at present, mainly be the damage and wear of gear, parts of bearings.These wearing and tearing occur may the pollution lubricating agent with the metal particle of rear surface, transmission efficiency is descended produce noise, and serious situation may cause break of gear tooth to cause compressor emergency shutdown.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of failure detector of 2.5MW wind-powered electricity generation gear case, and purpose is to carry out status surveillance, in time pinpoint the problems, in time handle, analyze from the sign that breaks down to time of thorough inefficacy, so that in time arrange maintenance.
For reaching the failure detector of above-mentioned purpose the utility model 2.5MW wind-powered electricity generation gear case, constitute by following structure: be located at the vibration transducer on high speed shaft and the slow-speed shaft, vibration transducer is connected with the condition monitoring case, the condition monitoring case passes through too, and netting twine is connected with low-voltage power distributing cabinet, low-voltage power distributing cabinet is passed to switch board at the bottom of the tower to signal by optical fiber, and switch board is given pulpit PC terminal by the network delivery of wind field at the bottom of the tower.
Described high speed shaft axially and radially be respectively equipped with high speed shaft axial vibration sensor and high speed shaft radial vibration sensor, slow-speed shaft axially and radially be respectively equipped with slow-speed shaft axial vibration sensor and slow-speed shaft radial vibration sensor.
Described vibration transducer is located at axially and directly making progress of high speed shaft and slow-speed shaft bearing (ball) cover respectively.
Described condition monitoring case is a CMS condition monitoring case, CMS condition monitoring case is gathered the signal that vibration transducer sends, digital signal processor in the CMS condition monitoring case is made comparisons signal that collects and parameter preset automatically, when finding to exceed normal value, send alarm signal to low-voltage power distributing cabinet, low-voltage power distributing cabinet with alarm signal by tower at the bottom of switch board pass to pulpit PC terminal.
The utility model has the advantages of: the utility model can accurately find location of fault and trouble spot, has shortened that gear case is repaired and wind-powered electricity generation compressor emergency shutdown time of causing, and can in time pinpoint the problems, and in time handles.
