The utility model discloses simple structure, reasonable in design, the utility model discloses not only simply but also practical, have easy operation, convenient operation, with low costs, detection efficiency is high, the accuracy is high, require the low grade advantage to the operating personnel experience.
Description
Technical field
The utility model relates to a kind of detection system, especially relates to the turn-to-turn short circuit detection system of a kind of practicality.
Background technology
Between circle, withstand voltage test is the test necessarily done in generator producer rotor winding assembling process. Major part producer is mainly pressurizeed to coil by voltate regulator at present, after test coil electric current, second circle electric current relatively upper carries out judging whether to there is turn-to-turn short circuit, if short circuit, carrying out continuing energising and making that coil short dot is overheated to carry out artificial hand and touch or detect out general short dot by expensive electromagnetic detection instrument, then carrying out monolithic and judge to get rid of one by one to find short dot. The detection of above form not only needs operator to have wide experience, and crosses length heat-up time and may damage turn-to-turn insulation, also there is the shortcomings such as complex process, cost height, detection efficiency be low simultaneously.
Practical novel content
In order to overcome the deficiency that prior art exists, the utility model provides the turn-to-turn short circuit detection system of the rotor winding of the band ventilation hole of the large turbo-type generator of a kind of practicality.
A turn-to-turn short circuit detection system for practicality, described detection system comprises megohmmeter, the dull and stereotyped chi of irony and two wires, and the dull and stereotyped chi one end of described irony is coated with imines insulating tape, and the dull and stereotyped chi the other end of irony is connected with detection coil; One end of one wire chi dull and stereotyped with irony is connected, and the other end is connected with megohmmeter positive pole; One end of another wire is connected with megohmmeter negative pole, and the other end is connected with detection coil.
As preferably, the height of described imines insulating tape is 6��12cm. It is convenient to hold, easy to operate.
As preferably, the electric wire that chi dull and stereotyped with irony is connected is fixed by welding on the dull and stereotyped chi of irony.
As preferably, described electric wire is welded on the dull and stereotyped chi one end of the irony being coated with imines insulating tape.
The utility model structure is simple, reasonable in design, and the utility model is not only simple but also practical, have simple to operate, easy to operate, cost is low, detection efficiency height, accuracy height, to advantages such as the requirement of operator's experience are low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but the claimed scope of the utility model is not limited to this.
With reference to Fig. 1, the turn-to-turn short circuit detection system of a kind of practicality, described detection system comprises megohmmeter 1, the dull and stereotyped chi 4 of irony and two wires 2, and dull and stereotyped chi 4 one end of described irony is coated with imines insulating tape 3, and dull and stereotyped chi 4 the other end of irony is connected with detection coil 5; The height of described imines insulating tape 3 is 10cm, is convenient to hold, easy to operate. One end of one wire chi 4 dull and stereotyped with irony is connected, and the other end is connected with megohmmeter 1 positive pole; The electric wire that chi 4 dull and stereotyped with irony is connected is fixed by welding on the dull and stereotyped chi 4 of irony, and described electric wire is welded on the dull and stereotyped chi one end of the irony being coated with imines insulating tape; One end of another wire is connected with megohmmeter 1 negative pole, and the other end is connected with detection coil 5.
Principle of work of the present utility model is: will detect coil 5 and be energized one a little after the meeting, lie on testing table, megohmmeter 1 is transferred to and surveys insulation resistance value 500V shelves, fasten detection coil 5 insulating surfaces with the dull and stereotyped chi 4 of irony and streak all ventilation holes (major part be all that disposed at air vent is jagged cause short circuit) successively, when insulation resistance value is shown as 0, point is short dot, short dot streaks and also can produce energising spark instantaneously, so being easy to judge short dot, after judging short dot, carry out insulation processing.
