Abstract
The invention discloses a method for measuring the resistance of a crimped section of a copper and aluminum composite row. The method comprises the following steps that: (1) a microvolt meter is connected to the crimped section of the copper and aluminum composite row, and the positive and negative poles of a direct-current (DC) welder are connected onto the copper and aluminum composite row; and (2) the DC welder outputs an electric current, the voltage of the crimped section of the copper and aluminum composite row is measured, and the resistance of the crimped section of the copper and aluminum composite row is obtained through a manner that the measured voltage value is divided by an electric current value. According to the method for measuring the resistance of the crimped section of the copper and aluminum composite row, the resistance of the crimped section of the copper and aluminum composite row is indirectly measured through measuring the voltage, the measured numerical values are accurate, and the measurement method is simple and convenient and is easy to operate.
Description
Technical field
The invention belongs to the Electrical Measurement Technology field, be specifically related to the measuring method of the compound row's crimp segment of a kind of copper aluminium resistance.
Background technology
Conductor resistance is generally directly measured with the multimeter resistance grade, but because the compound row's crimp segment of copper aluminium resistance value is very little, it is big to measure the compound row's crimp segment of copper aluminium resistance error with multimeter, and measured value can't react the real electric value value of the compound row's crimp segment of copper aluminium.
Summary of the invention
By Given this, the purpose of this invention is to provide the measuring method of the compound row's crimp segment of a kind of copper aluminium resistance, measure the compound row's crimp segment of copper aluminium resistance indirectly through surveying voltage, it is accurate to measure numerical value, and measuring method is simple and easy to operate.
To achieve these goals, the present invention adopts following technical scheme:
The measuring method of the compound row's crimp segment of a kind of copper aluminium resistance wherein, comprises the steps:
Further, the output current of described DC welder is the Constant Direct Current electric current.
Beneficial effect of the present invention is:
The present invention adopts indirect method to record the compound row's crimp segment of copper aluminium resistance; The both positive and negative polarity that on the compound row of copper aluminium, connects DC welder; Make the DC welder output current; Spacing is measured the compound row's of copper aluminium pressure drop, uses the voltage drop value of measuring divided by the welding machine output current value then, has just drawn the resistance value of the compound row pressure interface of copper aluminium.Method of the present invention is compared in the prior art with the direct measured resistance value of multimeter resistance grade, can obtain the resistance of the compound row pressure section of copper aluminium more accurately, and method is simple and easy to operate, and accuracy is high, can check the compound row's of copper aluminium crimping effect effectively.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 characteristic are set forth in instructions subsequently, and to a certain extent, based on being conspicuous to those skilled in the art to investigating of hereinafter, perhaps can from practice of the present invention, obtain instruction.Target of the present invention can realize through the structure that is particularly pointed out in following instructions or the accompanying drawing and obtain with other advantages.
Description of drawings
Synoptic diagram when Fig. 1 measures the compound row's crimp segment of copper aluminium resistance value for the present invention.
Embodiment
As shown in Figure 1, the positive and negative electrode of DC welder 1 is connected to the compound row of copper aluminium 6 two ends through cable 2, and microvoltmeter 4 is connected to the compound row's crimp segment of copper aluminium 5 two ends through lead 3.DC welder 1 output Constant Direct Current electric current is measured the compound row's crimp segment of copper aluminium voltage with microvoltmeter 4 intercepts then, is the crimp segment resistance value with measured voltage values divided by current value.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Other modifications that those of ordinary skills make technical scheme of the present invention perhaps are equal to replacement; Be common variation of the present invention, only otherwise break away from the spirit and the scope of technical scheme of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
