Abstract
The utility model discloses a device for rapidly testing the direct-current resistances of conductors, which comprises a direct-current resistance bridge, two connecting wires, two test fixtures and a coolant trough containing coolant, the direct-current resistance bridge is respectively connected with the two test fixtures for clamping a tested sample through the two connecting wires, and the test fixtures are extended into the coolant of the coolant trough. Compared with conventional direct-current resistance testers for conductors, the device has the advantages that: the testing method breaks through the conventional requirement for constant temperature time, the coolant is adopted to forcibly cool the tested sample, so that the device has the effects of remarkably shortening the testing time and increasing the testing efficiency, and consequently, a test can be rapidly and easily carried out while meeting the requirement of the national standard.
Description
Technical field
The utility model relates to a kind of conductor DC resistance proving installation, particularly a kind of fast detecting conductor DC resistance device.
Background technology
At present, conventional conductor DC resistance proving installation requires sample is statically placed in the isoperibol usually, more than 4 hours, just can carry out next step test operation through constant temperature then.Whole process is consuming time longer, complex operation, and work efficiency is obviously lower.
In order to improve the testing crew work efficiency, reduce its labour intensity, the inventor has invented fast detecting conductor DC resistance device, has this case to produce then.
The utility model content
The purpose of the utility model is to provide a kind of fast detecting conductor DC resistance device, to improve detection speed, makes simple to operationly, improves the work efficiency of testing crew.
To achieve these goals, the solution of the utility model is:
Fast detecting conductor DC resistance device; Cooling liquid bath by direct current resistance electric bridge, connection lead, test fixture and splendid attire liquid coolant is formed; The direct current resistance electric bridge connects lead through two and connects two test fixtures that are used for the clamping sample respectively, and test fixture stretches in the liquid coolant of cooling liquid bath.
Said test fixture is made up of base and the clip that is fixed on the base, and the direct current resistance electric bridge connects lead through two and connects clip respectively.
After adopting such scheme; The utility model is compared with the conductor DC resistance proving installation of routine; Method of testing breaks through conventional constant temperature time requirement; Adopt liquid coolant to force the cooling sample, have the remarkable shortening test duration, improve the effect of test job efficient, make that test operation is able to carry out and comply with the national standard requirements again fast, simple and direct.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Label declaration
1 direct current resistance electric bridge 2 connects lead
3 samples (conductor), 4 test fixtures
41 bases, 42 clips
5 liquid coolants, 6 cooling liquid levels
7 cooling liquid baths.
Embodiment
As shown in Figure 1, the utility model has disclosed fast detecting conductor DC resistance device, is made up of the cooling liquid bath 7 of direct current resistance electric bridge 1, connection lead 2, test fixture 4 and splendid attire liquid coolant 5.
Direct current resistance electric bridge 1 connects lead 2 through two and connects two test fixtures 4 respectively, and this test fixture 4 is to be used for clamping sample 3 (conductor), and test fixture 4 stretches in the liquid coolant 5 of cooling liquid bath 7.
The concrete structure of test fixture 4 can as shown in the figurely be made up of base 41 and the clip 42 that is fixed on the base 41, and direct current resistance electric bridge 1 connects lead 2 through two and connects clip 42 respectively.
During use, on test fixture 4, sample 3 is under the cooling liquid level 6 sample 3 fixed clamp; Force cooling 10～15 minutes through 5 pairs of samples of liquid coolant 3; The temperature of sample 3 reduced to rapidly with the temperature of liquid coolant 5 equate, measure the resistance value of sample 3 then with direct current resistance electric bridge 1, again with the temperature value of liquid coolant 5 as the probe temperature value; Measured data is converted, promptly draw the dc resistance of sample 3 in the time of 20 ℃.
The utility model test process is simple and convenient, carries out simple modifications according to present equipment and just can use.Carry out the conductor DC resistance test with the utility model, about 15～20 minutes consuming time of whole test process, omnidistance 10% of the conventionally test method that is merely consuming time; Shortened the running time greatly, detection speed is fast, has improved testing efficiency greatly; Improved the work efficiency of testing crew greatly; And the whole test flow process complies with the national standard requirements fully, and gained data accurate and effective has good economic benefit and social benefit.
