Put, working environment is severe, larger by the Effect of Natural Disaster such as wind and snow, saline and alkaline, mist, particularly contact net anchorage device, its work
State will directly affect the dynamic characteristic and current carrying quality of pantograph and contact net, will influence traffic safety under fault condition.Connect
Ratchet angles offset causes the most common failure phenomenon that falling mound clamping stagnation is compensator failure in net-fault ratchet compensation ending fitting, to just
Often operation causes very big interference, seriously affects the operation security of electric railway.
With the rapid development of sensor and electronic measurement technique, the Condition Monitoring Technology of contact net system will also have compared with
Big progress.Implementation monitoring is carried out to contact net ratchet angles using the monitoring device of advanced monitoring technology and modernization, is carried
Preceding advance notice incipient fault hidden danger, prevents trouble before it happens, is the guarantee for improving tractive power supply system safe and reliable operation, is to realize electrically
Change railway security, stabilization, the important guarantee of reliability service.
The working status of contact net anchorage device will directly affect the dynamic characteristic and current carrying quality of pantograph and contact net.
Ratchet angles offset causes the most common failure phenomenon that falling mound clamping stagnation is contact net anchorage failure of apparatus.In view of the above-mentioned problems, need
Monitoring contact net system ratchet angles offset parameter in real time.
The content of the invention
The purpose of this utility model is to provide a kind of contact net system ratchet angles monitoring device, realizes that contact net ratchet is mended
Repay the real-time state monitoring of ratchet angles in ending fitting, it is possible to provide reliable, accurate, comprehensive monitoring data judge contact net system
The working status of system.
Technical solution is used by the utility model：
A kind of contact net system ratchet angles monitoring device, it is characterised in that：
Including the housing being installed on ratchet compensation stent, angular transducer and electromagnetism interference electricity are installed in housing
Road, wherein angular transducer use accelerometer；
The manifold phase that angular transducer and anti-electromagnetic interference circuit are casted anchor on pillar by flexible cable with being installed on compensation
Even intercommunication.
Housing has the base of U-shaped structure, and the U-lag of ratchet compensation stent inserted base is simultaneously fixedly clamped by bolt.
The communication interface of angular transducer, anti-electromagnetic interference circuit and manifold uses RS485.
The utility model has the following advantages：
1st, product is connected by flexible cable with manifold, realizes data communication and equipment power supply, and communication interface uses
RS485.Housing is fastenedly connected with base by screw, the U-shaped structure of base, prepared screw-bolt hole.Base is buckled in ratchet compensation
On stent, it is fastened by bolts, overall structure is stable, reliable, easy for installation.
When using communication, need to set solar panels, enclosed inside battery, antenna and electronics outside this product
Circuit.So as to cancel flexible cable connecting line, overall structure simplifies.
2nd, housing and base use metal material, and surface carries out anodized and forms oxide-film, and increase product is hard
The characteristic such as degree, wear-resisting, can effectively improve the anti-blown sand performance of product,
4th, housing carries sealing structure, and inside installation sealant rubber ring can effectively prevent field ring, it can be achieved that housing is totally-enclosed
The entrance of sand and dust, moisture in border；
5th, enclosure interior integrates the angular transducer based on accelerometer, anti-electromagnetic interference circuit and connection cables, can be real
The accurate measurement of existing ratchet angles data, gathered data can be transmitted to by flexible cable or communication data concentrator into
Row process of fitting treatment and the data platform that distal end operation management mechanism is transmitted to through communication, unite easy to operation management mechanism
One analysis data, find that contact net system security risk is excluded, and can increase substantially the reliable of tractive power supply system in time
Property and security.
