Description
Technical field
The invention belongs to technical field of electrical measurement, be specifically related to the measuring method of a kind of Copper-Aluminum compound row crimp segment resistance.
Background technology
Conductor resistance is generally directly measured with multimeter resistance grade, but due to Copper-Aluminum compound row crimp segment resistance value very little, measure Copper-Aluminum compound row crimp segment resistance error with multimeter large, measured value cannot react the real electric value value of Copper-Aluminum compound row's crimp segment.
Summary of the invention
By Given this, the object of this invention is to provide the measuring method of a kind of Copper-Aluminum compound row crimp segment resistance, by surveying voltage indirect inspection Copper-Aluminum compound row crimp segment resistance, measure numerical value accurate, measuring method is simple and easy to operate.
To achieve these goals, the present invention is by the following technical solutions:
A measuring method for Copper-Aluminum compound row crimp segment resistance, wherein, comprises the steps:
Step one, connects microvoltmeter in Copper-Aluminum compound row crimp segment, and the positive and negative electrode of DC welder is connected on Copper-Aluminum compound row;
Step 2, DC welder output current, measures Copper-Aluminum compound row crimp segment voltage, and namely the magnitude of voltage of measurement is obtained Copper-Aluminum compound row crimp segment resistance value divided by current value.
Further, the output current of described DC welder is Constant Direct Current electric current.
Beneficial effect of the present invention is:
The present invention adopts indirect method to record Copper-Aluminum compound row crimp segment resistance, Copper-Aluminum compound row connects the both positive and negative polarity of DC welder, make DC welder output current, spacing measures the pressure drop of Copper-Aluminum compound row, then use the voltage drop value measured divided by welding machine output current value, just draw the resistance value of Copper-Aluminum compound row pressure interface.Method of the present invention compared to existing technology in the direct measured resistance value of multimeter resistance grade, can obtain the resistance of Copper-Aluminum compound row pressure section more accurately, method is simple and easy to operate, and accuracy is high, the crimping effect that can effectively check Copper-Aluminum compound to arrange.The present invention is applicable to the crimping effect detection of all conductors, and application prospect is better.
Other advantages of the present invention, target and feature are set forth in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from the practice of the present invention.Target of the present invention and other advantages can be realized by structure specifically noted in instructions below or accompanying drawing and be obtained.
Accompanying drawing explanation
Fig. 1 be the present invention measure Copper-Aluminum compound row crimp segment resistance value time schematic diagram.
Embodiment
As shown in Figure 1, the positive and negative electrode of DC welder 1 is connected to Copper-Aluminum compound through cable 2 and arranges 6 two ends, and microvoltmeter 4 is connected to Copper-Aluminum compound row crimp segment 5 two ends through wire 3.DC welder 1 exports Constant Direct Current electric current, then measures Copper-Aluminum compound row crimp segment voltage, by measuring voltage value divided by current value and crimp segment resistance value with microvoltmeter 4 intercept.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, other amendments that those of ordinary skill in the art make technical scheme of the present invention or equivalently to replace, be common change of the present invention, only otherwise 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.
