Abstract
The invention relates to a current rising test line capable of alarm against overheat. The test line comprises suspension ring type bolts at the two ends of the line and an alarm system connected to the test line. During current rising test, if the temperature of a certain point of the whole test line rises rapidly due to the resistance of the point is slightly high, acoustic and optical alarm is emitted to an operator; and to prevent a joint from loosening caused by movement and vibration, the suspension ring type bolts are arranged at the two ends of the test line and enable safer and more convenient fastening. The current rising test line can be widely applied to the debugging process of a transformer station.
Description
Technical field
The present invention relates to a kind of rising test line, particularly relate to the rising test line with temperature alarm function.
Background technology
When transformer station secondary system debugging, need to carry out primary equipment rising test, namely apply big current to primary circuit, be mainly used in the test of current transformer.
At present, the method for up-flow is connected with once holding with two of tested mutual inductor respectively with two output terminals of current lifting device, then carries out applying big current as 100 amperes ~ 2000 amperes; Then observe and record in the enterprising line number value of the screen of measure and control device, protective relaying device.
Because the electric current applied is very large, if in tested loop and test wire, there is the slightly large point of resistance value, that this temperature can be caused to raise is very fast, affect current lifting device safe, affect test precision, increase meaningless energy resource consumption.But present widely used test wire is screwed in together by the stranded copper wire of certain length and press-fits Wiring nose at two ends and make.This test wire exists and not to form good contact, multiply test wire between Wiring nose and current lifting device binding post because of corrosion, loosened screw etc. owing to using for a long time and transporting and store the improper situation causing the disconnected stock of part.These reasons temperature that all can be formed on test wire on some point sharply raises and causes adverse consequences.

Embodiment
Below in conjunction with drawings and Examples, embodiments of the present invention are described in further detail.Following examples for illustration of the present invention, but can not be used for limiting the scope of the invention.
As shown in Figure 1, the present embodiment provides a kind of rising test line with temperature alarm function, comprises the hanging-ring type bolt at test wire two ends, and the warning system be connected with test wire.
Particularly, the described rising test line with temperature alarm function comprises left line nose 1, through the left fastening bolt 23 with left fastening spring 4 in left nostril 24 on left line nose 1, and welding loosens the locking open cup 2 in the left side turning hole 3 with a left side, left line nose 1 has positive pole through wires hole 22, negative pole through wires hole 21, be each passed through positive pole having insulation conducting wire 6, negative pole having insulation conducting wire 7, described left fastening bolt 23 there is left locking round catch 26, left suspension ring 5, one end of positive pole having insulation conducting wire 6 connects the positive terminal of audible-visual annunciator 9, the other end connect be formed in advance in multiply copper conductor 10 with the thermistor wire 11 with thermally conductive insulating layer 27, and insulate with multiply copper conductor 10 phase, the alarm end 12 far away of thermistor wire 11 and the right-hand member of multiply copper conductor 10 are by the right pressing groove group 19 phase compact siro spinning technology on right line nose 16, negative pole having insulation conducting wire 7 other end to be compressed with the left end of multiply copper conductor 10 by left pressing groove group 20 and is connected, right fastening bolt 18 is installed with right fastening spring 17 and has right locking round catch 28, right suspension ring 13, through the right fastening bolt 18 with right fastening spring 17 in right nostril 25 on right line nose 16, and welding loosens the locking open cup 15 in the right side turning hole 14 with the right side.
The rising test line with temperature alarm function of the present embodiment is when being connected with the wiring hole on current lifting device, left fastening bolt 23 is inserted current lifting device wiring hole, by twisting the left suspension ring 5 on left fastening bolt 23, left fastening bolt 23 is just tightened gradually, left fastening spring 4 is also compressed gradually, and left line nose 1 is with regard on the wiring hole being attached to current lifting device tightly.Rising test line of the present invention is when the wiring hole once held with tested mutual inductor is connected, right fastening bolt 18 is inserted current lifting device wiring hole, by twisting the right suspension ring 13 on right fastening bolt 18, right fastening bolt 18 is just tightened gradually, right fastening spring 17 is also compressed gradually, right line nose 16 just being attached on wiring hole that tested mutual inductor once holds tightly.
When the rising test line with temperature alarm function of embodiment is when starting up-flow, flowed back to the negative pole end of audible-visual annunciator 9 by its positive terminal, positive pole having insulation conducting wire 6, thermistor wire 11, multiply copper conductor 10, negative pole having insulation conducting wire 7 from the small direct current of audible-visual annunciator 9.Resistance is caused to raise if there is the reasons such as breakpoint in the upper stranded copper wire of certain point in whole piece test wire, so the meeting of this point sends very large heat, these heats pass to thermistor wire 11 by thermally conductive insulating layer 27, now the resistance of thermistor wire 11 will raise, when audible-visual annunciator 9 detects that the resistance of thermistor wire 11 becomes large, acousto-optic hummer then on audible-visual annunciator sends warning information, and alert is noted.
If once right line nose 16, left line nose 1 are not tightened with the equipment that is connected, this temperature is caused to raise, then heat can by the right line nose 16 of metal quality or left line nose 1, pass on multiply copper conductor 10, and then pass to thermistor wire 11 by thermally conductive insulating layer 27, now the resistance of thermistor wire 11 will raise, when audible-visual annunciator 9 detects that the resistance of thermistor wire 11 becomes large, then send warning information, alert is noted.
Audible-visual annunciator 9 designs in the one end near current lifting device, is because staff will be had in rising test to operate current lifting device, can finds the alerting signal of audible-visual annunciator timely.
Above embodiment is only for illustration of the present invention, but not limitation of the present invention.Although with reference to embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, various combination, amendment or equivalent replacement are carried out to technical scheme of the present invention, do not depart from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of right of the present invention.
