Description
Technical field
Electrical generator fields are the utility model is related to, more particularly to a kind of hydraulic generator rotor carbon brush abrasion amount automatic measurement
Device.
Background technology
Traditional hydraulic generator rotor carbon brush brush holder structure is in general tongue piece spring compression carbon brush, as shown in Figure 3.
Carbon brush is because the rotation of collector ring can produce abrasion, when need to find that carbon brush length is unsatisfactory for service requirement by manual inspection, in time
Change.But large-sized water turbine generator rotor carbon brush number is more, layout is intensive, is less susceptible to find excessive wear by inspection
Carbon brush；Cause carbon brush also more difficult by manual inspection with collector rings of rotors loose contact if brush carrier or tongue piece spring loosen simultaneously
It was found that tongue piece spring also exists after loosening falls into rotor rotary part, larger potential safety hazard be present.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of hydraulic generator rotor carbon brush abrasion amount and surveyed automatically
Device is measured, the device can be detected and monitored to rotor carbon brush abrasion amount, avoid potential safety hazard caused by artificial missing inspection.
In order to solve the above technical problems, technical scheme is used by the utility model:A kind of hydraulic generator rotor carbon
Brush wear amount self-operated measuring unit, including collector ring, carbon brush, carbon brush fixing frame and brush carrier, collector ring are arranged on armature spindle, carbon
Brush is contacted under fixation of the carbon brush fixing frame with brush carrier with collector ring, and pressure sensor, carbon brush are set on the carbon brush fixing frame
Compression spring is set between tail end and pressure sensor, and pressure sensor is electrically connected with controller, and the controller is with calculating
Machine connects.
In preferable scheme, the carbon brush tail end connects the first guide rod, and the second guide rod is connected on carbon brush fixing frame, the
One guide rod and the second guide rod are on the same line, gap between the first guide rod and the second guide rod be present, compression
Both ends of the spring is sleeved on the first guide rod and the second guide rod, and pressure sensor is between compression spring and carbon brush fixing frame
Pressure sensor is located at compression spring one end.
In preferable scheme, the quantity of the compression spring and pressure sensor is multiple.
A kind of hydraulic generator rotor carbon brush abrasion amount self-operated measuring unit provided by the utility model, by carbon brush with
Compression spring is set between carbon brush fixing frame, it is ensured that carbon brush head is pressed on current collection ring surface, and due to compression spring with
Pressure sensor is set between fixed mount, and when the friction between carbon brush and collector ring causes carbon brush abrasion, compression spring is due to certainly
The elastic force elongation of body, forces carbon brush further close to make up the wear extent of carbon brush to collector ring, simultaneously because compression spring is stretched
Long, compression spring reduces to the pressure of pressure sensor, and the pressure value changes measured by pressure sensor can judge carbon brush
Wear extent.In preferable scheme, compression spring is sleeved on the first guide rod and the second guide rod, the first guide rod and second
Guide rod ensures the direction of motion of compression spring all the time along straight line direction, while between the first guide rod and the second guide rod
Gap be present can make compression spring be relatively easy to installation, facilitate the replacing of compression spring.Compression spring and pressure sensor
Quantity to be multiple, can prevent from influenceing the use of whole device because of indivedual spring failures, while to multiple pressure sensors
Pressure value be acquired, it is more relatively reliable than single data accurate.
