Embodiment
Embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples.Following embodiments are used for
Illustrate the present invention, but cannot 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, including test wire both ends
Hanging-ring type bolt, and the alarm system being connected with test wire.
Specifically, the rising test line with temperature alarm function includes left line nose 1, on left line nose 1
The left fastening bolt 23 with left fastening spring 4 is passed through in left nose hole 24, and welds the left locking opening with left loosening turn hole 3
Cup 2, cathode threading hole 22, anode threading hole 21 are provided with left line nose 1, is each passed through cathode having insulation conducting wire 6, anode band
Insulated conductor 7, there is left locking round catch 26, left hanging ring 5 in the left fastening bolt 23, and one end of cathode having insulation conducting wire 6 connects
Connect the positive terminal of audible-visual annunciator 9, the pre- heat carried with thermally conductive insulating layer 27 being formed in multiply copper conductor 10 of other end connection
Quick resistance wire 11, and insulate with 10 phase of multiply copper conductor；The remote alarm end 12 of thermistor wire 11 and multiply copper conductor 10
Right end is closely connected by right 19 phase of pressing groove group on right line nose 16；7 other end of anode having insulation conducting wire passes through left compression
The left end of groove group 20 and multiply copper conductor 10, which compresses, to be connected；Right fastening spring 17 is installed with right fastening bolt 18 and has right locking circle
Catch 28, right hanging ring 13；The right fastening bolt 18 with right fastening spring 17 is passed through in right nostril 25 on right line nose 16；
And weld the right locking open cup 15 with right loosening turn hole 14.
The rising test line with temperature alarm function of the present embodiment, will when being connected with the wiring hole on current lifting device
Left fastening bolt 23 is inserted into current lifting device wiring hole, and by twisting the left hanging ring 5 in left fastening bolt 23, left fastening bolt 23 is just gradual
Tighten, left fastening spring 4 is also gradually compressed, left line nose 1 just being attached on the wiring hole of current lifting device tightly.The present invention's
Rising test line is inserted into current lifting device wiring when the wiring hole once held with tested mutual inductor is connected, by right fastening bolt 18
Hole, by twisting the right hanging ring 13 in right fastening bolt 18, right fastening bolt 18 just gradually tightens, right fastening spring 17 also gradual quilt
Compress, on the wiring hole for being attached to tested mutual inductor and once having held of right line nose 16 just tightly.
When the rising test line with temperature alarm function of embodiment is starting up-flow, from audible-visual annunciator 9
Small direct current passes through its positive terminal, cathode having insulation conducting wire 6, thermistor wire 11, multiply copper conductor 10, anode tape insulation
Conducting wire 7 flows back to the negative pole end of audible-visual annunciator 9.To draw if there are the reasons such as breakpoint in the upper stranded copper wire of certain point in whole test wire
Play resistance value rise, then the meeting of the point sends very big heat, these heats are transmitted to thermistor wire by thermally conductive insulating layer 27
11, at this time the resistance value of thermistor wire 11 will raise, when audible-visual annunciator 9 detects that the resistance value of thermistor wire 11 becomes larger
When, then the acousto-optic buzzer on audible-visual annunciator sends warning information, prompts operating personnel to pay attention to.
If once right line nose 16, left line nose 1 are not tightened with the equipment that is connected, the temperature is caused to raise, then
Heat can be by metal quality right line nose 16 or left line nose 1, pass on multiply copper conductor 10, and then exhausted by heat conduction
Edge layer 27 is transmitted to thermistor wire 11, and the resistance value of thermistor wire 11 will raise at this time, when audible-visual annunciator 9 detects temperature-sensitive
When the resistance value of resistance wire 11 becomes larger, then warning information is sent, prompt operating personnel to pay attention to.
Audible-visual annunciator 9 is designed in one end of close current lifting device, is because to have staff right in rising test
Current lifting device is operated, and can timely find the alarm signal of audible-visual annunciator.
Embodiment of above is merely to illustrate the present invention, rather than limitation of the present invention.Although with reference to embodiment to this hair
It is bright to be described in detail, it will be understood by those of ordinary skill in the art that, to technical scheme carry out it is various combination,
Modification or equivalent substitution, without departure from the spirit and scope of technical solution of the present invention, the right that should all cover in the present invention is wanted
Ask among scope.
