Abstract
The invention discloses an intelligent detection apparatus for contact travel of a tulip contact of a circuit breaker, and relates to the field of circuit breaker detection structures. The apparatus comprises a monitor body arranged on a contact arm; a position inductive probe is arranged on the monitor body; the position inductive probe is located in an inner cavity of the tulip contact and axially arranged along an inner cavity of a tulip tap; a matching cavity matched with the position inductive probe is formed in a static contact opposite to the tulip contact; and measurement is started when the position inductive probe enters the matching cavity, and is stopped after the tulip contact is in full contact with the static contact. According to the structure, the abrasion loss of the contact in working can be measured in time, and a measurement result is displayed, so that the structure damage caused by excessive abrasion is avoided, the potential safety hazards are reduced, and the service life of the circuit breaker is prolonged.
Description
Technical field
The present invention relates to breaker detection construction applications, more particularly to a kind of breaker Mume flower contact contacting travel intelligence
Detection means.
Background technology
Contact system is the important component part of breaker, touch spring parameter and contact end pressure value in contact system
Design is very crucial, is directly connected to the tolerance performance in short-term of breaker.Improving breaker KA Rms value can increase B
The selective protection scope of class breaker, effectively improves the reliability of electrode difference protection, the generation of the accidents such as tripping operation that prevent from bypassing the immediate leadership.
Under short-circuit current rush, huge electrodynamic repulsion force can cause contact between contact to reduce and cause overheated or even melting welding, make to break
Road device cannot continue normal work；Even also can result in dynamic and static contact to scold out, cause hard arc to burn contact and open circuit
Device.In actual applications the time of contact of dynamic/static contact is difficult measurement, and the time of contact of dynamic/static contact individually contacts with contact
There is corresponding relation between stroke, therefore can be by measuring the independent contacting travel of contact come calculation contact time.In actual survey
In amount, in order to ensure the accuracy of the independent contacting travel measurement of contact, height must be carried out to killer switch actuating length curve
The measurement of precision, its precision should be in 0.5mm ranks.However, high-precision measurement often means that the measurement apparatus of complexity.
The content of the invention
The invention mainly solves the technical problem of a kind of breaker Mume flower contact contacting travel intelligent detection device is provided,
Solve the movement travel measurement problem of breaker Mume flower contact.
To solve above-mentioned technical problem, one aspect of the present invention is to provide a kind of breaker Mume flower contact and connects
Tactile stroke intelligent detection device, including the monitor body being arranged on contact arm；The monitor body is provided with location sensitive
Probe；The location sensitive probe is located in Mume flower contact inner chamber and along the axially arranged of plum blossom tap inner chamber；Touch in plum blossom
Head to static contact be provided with the mating cavity for coordinating location sensitive probe；Location sensitive probe is from entering mating cavity
Start measurement, after Mume flower contact and static contact full contact measurement is stopped.
Preferably, Mume flower contact includes contact arm, contact and spring；The contact arm is axially arranged with the Mume flower contact
Chamber；One end of the contact is arranged on the end of contact arm, and its other end is contacted with the rotary surface of static contact；Cover on the contact
Fill the spring.
Preferably, the monitor body passes through electric signal connected with computer control device；Computer control device is provided with
Show reading mechanism.
The invention has the beneficial effects as follows：A kind of breaker Mume flower contact contacting travel intelligent detection device is provided, can and
When measure contact wear extent at work, and show measurement result, it is to avoid the structural failure caused because abrasion is excessive, drop
Low potential safety hazard, improves the service life of breaker.

It is axially arranged.Mume flower contact to static contact 3 on be provided with the mating cavity of cooperation position inductive probe 2, location sensitive is visited
2 start measurement from into mating cavity, and after Mume flower contact and the full contact of static contact 3 measurement is stopped.Mume flower contact include contact arm,
Contact and spring, contact arm is axially arranged with Mume flower contact inner chamber.One end of contact be arranged on contact arm end, its other end with it is quiet
The rotary surface contact of contact.Pocketed springs on contact.Monitor body is by electric signal connected with computer control device, microcomputer control
Device processed is provided with display reading mechanism.Breaker propulsion operating position is initial, and Mume flower contact starts to contact with static contact, position
Inductive probe touches static contact measurement and starts, after breaker is shaken to operating position, measurement terminate and read Mume flower contact with
The actual contacting travel of static contact.
Embodiments of the invention are the foregoing is only, the scope of the claims of the present invention is not thereby limited, it is every using this
Equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
Domain, is included within the scope of the present invention.
