Abstract
An extended forcipate current and resistance tester consists of a jaw, a telescopic sleeve and a master meter, and is characterized in that the jaw is arranged at the front end of the telescopic sleeve; the rear end of the telescopic sleeve is connected with the master meter; the telescopic sleeve is sleeved with a big square pipe and a small square pipe; and the master meter is provided with a USB data interface. The utility model relates to electric data measuring devices, particularly to the extended forcipate current and resistance tester.
Description
Technical field
This patent relates to the electric power data measurement mechanism, is specially the pincerlike current resistor tester of a kind of extension.
Background technology
Pincerlike earth resistance tester has another name called pincerlike ground meter.The grounding resistance measurement that is widely used in electric power, telecommunications, meteorology, oil field, building and industrial electrical installation.Pincerlike ground meter need not break off down conductor when measurement has the earthed system in loop, do not need auxiliary electrode, safely and fast, easy to use.Pincerlike ground meter energy measurement goes out the earth fault that can't measure with classic method, can be applied to the occasion that classic method can't be measured, because the measurement of pincerlike ground meter is the integrated value of grounding body resistance and ground lead resistance.Pincerlike ground meter has the branch of alligator pliers mouth and circle jaw.The alligator pliers mouth is suitable for the occasion of band steel ground connection especially.The ultimate principle of pincerlike ground meter measurement of Grounding Resistance is to measure loop resistance.The associated jaw portion of split-core type meter is made up of potential winding and current coil.Potential winding provides pumping signal, and on tested loop, responds to an electromotive force E.Under the effect of electromotive force E, will produce electric current I in tested loop.Split-core type meter is measured E and I, and can obtain measured resistance R through following formula.The ultimate principle that pincerlike ground meter is measured electric current is identical with the measuring principle of current transformer.The alternating current I of measured lead, through electric current magnet ring and induction current I1 of current coil generation of jaw, split-core type meter is measured I1, can obtain measured current I through following formula.But present equipment is probe clip and meter body to be combined, and is unfavorable for the use of some particular surroundingss, and such as the cable that buries on ground cable or the pylon, existing equipment uses very inconvenience.The measurement of data simultaneously needs manual record, changes being entered in the computer inefficiency again.
Summary of the invention
The purpose of this patent is to above technical matters, and a kind of pincerlike current resistor tester of extension that is suitable for narrow space operation and direct typing computer is provided.
The concrete technical scheme of this patent is following:
The pincerlike current resistor tester of extension is made up of jaw, extension sleeve, master meter, and it is characterized in that: jaw is arranged on the extension sleeve front end, and the extension sleeve rear end connects master meter, and extension sleeve has big or small square tube fit, and master meter is provided with the usb data interface.
The setting of extension sleeve can make the flexible inconvenience that has solved environmental baseline difference in the actual use and caused of measuring of jaw.
Description of drawings
Fig. 1 is this patent structural representation.
Wherein, 1---jaw, 2---extension sleeve, 3---master meter, 4---data line.
Embodiment
Below in conjunction with embodiment and accompanying drawing this patent is described further.
The pincerlike current resistor tester of extension; Form by jaw, extension sleeve, master meter; Jaw is arranged on the extension sleeve front end, and the extension sleeve rear end connects master meter, and extension sleeve has big or small square tube fit; Master meter is provided with the usb data interface, and the extension sleeve of big or small square tube fit is regulated its pattern length as required to extend or to shorten the distance between jaw and the master meter.
The setting of extension sleeve can make the flexible inconvenience that has solved environmental baseline difference in the actual use and caused of measuring of jaw.
