Abstract
The utility model discloses a conductor DC resistance on-line detection apparatus, comprising a DC resistor bridge, connection leads, detection clamps, and main and sub liquid coolant tanks for containing a liquid coolant, wherein the DC resistor bridge is connected with two detection clamps used for clamping a sample to be detected through two connection leads, the detection clamps extend into the liquid coolant of the main liquid coolant tank, the side plates at both ends of the main liquid coolant tank are provided with openings through which the sample to be detected can pass, and the main liquid coolant tank is arranged in the sub liquid coolant tank. The conductor DC resistance on-line detection apparatus employs the main and sub liquid coolant tanks to forcedly cool the sample to be detected, thereby breaking through the conventional constant temperature time demand, having the effects of greatly shortening detection time and increasing detection work efficiency, and enabling the on-line detection operation to be rapidly and simply performed and to satisfy the demand of national standards; and the detection apparatus can enable the sample waste caused by detection to be eliminated, and the waste in the process of production to be reduced, and has good economic benefits and social benefits.
Description
Technical field
The utility model relates to a kind of conductor DC resistance proving installation, particularly a kind of online detection conductor DC resistance device.
Background technology
At present, conventional conductor DC resistance proving installation requires one section tested sample of intercepting usually and is statically placed in the isoperibol, 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, and sample can't re-use after detecting, and can only do to scrap processing, and the waste that produces in the long-term production is also comparatively considerable.
In order to improve the testing crew work efficiency, reduce its labour intensity, eliminate because of detecting the sample that produces and scrap, cut the waste, the inventor has invented online detection 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 online detection conductor DC resistance device, to improve detection speed, eliminates the sample that detects generation and scraps, and cuts the waste.
To achieve these goals, the solution of the utility model is:
Online detection conductor DC resistance device; Form by direct current resistance electric bridge, the main refrigerant fluid groove that connects lead, test fixture and splendid attire liquid coolant and auxilliary cooling liquid bath; The direct current resistance electric bridge connects lead through two and connects two test fixtures that are used for the clamping sample respectively; Test fixture stretches in the liquid coolant of main refrigerant fluid groove, has on the two end side panels of main refrigerant fluid groove and can hold the opening that sample passes through, and the main refrigerant fluid truss is in auxilliary 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.
The bottom of said main refrigerant fluid groove has leg, and leg stands in the liquid coolant of auxilliary cooling liquid bath, makes the main refrigerant fluid truss at auxilliary cooling liquid bath.
After adopting such scheme; The utility model is compared with the conductor DC resistance proving installation of routine, and method of testing breaks through conventional constant temperature time requirement, adopts main and auxiliary two cooling liquid baths to force the cooling sample; Effect with remarkable shortening test duration, raising test job efficient; Make that test operation is able to onlinely carry out and comply with the national standard requirements again fast, simple and direct, and, needn't one section of intercepting during this test but the direct-on-line test; Can eliminate because of detecting the sample that produces and scrap, reduce the waste of production run.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
