Description
Technical field
The utility model relates to a kind of point inspection device, particularly a kind of earth resistance tester point inspection device.
Background technology
Earth resistance tester belongs to Electric Security Tester device, uses extensively in enterprise's activity in production, and the normal function performance of present earth resistance tester, unfailing performance and order of accuarcy, people often depend on measurement and calibration and daily spot check work ensures.Instrument measurement and calibration is generally carry out once every year, is completed by metrological service, but the standardization of calibration process, the data provided and certificate and accuracy all need specification and evaluation.At present, the detecting method that people use is very simple, normally by output terminal short circuit or disconnection simply, or the method for contact resistance device is verified, observe it when starting earth resistance tester and whether send early warning signal, such detecting method is very simple and crude coarse, reliably not accurate enough.And Some Enterprises oneself have developed simple spot check device, but these spot check devices generally do not meet the demands, mostly show as design imperfect, select easily generate heat change, spot check of element to operate not easily many-sided problem such as execution, poor stability.Normal function for earth resistance tester shows, order of accuarcy and its unfailing performance, we can be ensured by daily spot check work, but problem is that the professional knowledge of operational staff is not comprehensive, and the complex operation of existing spot check device is complicated, if detecting method and operation exist deviation, not predictable consequence can be brought because instrument lost efficacy equally.
Therefore, how to realize a kind of rational in infrastructure, simple to operation, detect accurately and reliably, can by detect guarantee earth resistance tester normal function performance, order of accuarcy and functional reliability earth resistance tester point inspection device be technical matters urgently to be resolved hurrily in the industry.
Utility model content
Fundamental purpose of the present utility model is to provide a kind of earth resistance tester point inspection device, be intended to realize one rational in infrastructure, simple to operation, detect accurately and reliably, can by detect guarantee earth resistance tester normal function performance, order of accuarcy and functional reliability earth resistance tester point inspection device.
The utility model proposes a kind of earth resistance tester point inspection device, can detect earth resistance tester, comprise the box body be made up of insulating material, box body is provided with common return end, by end, report to the police and hold, common return end and warning are connected with the first resistance R1 that operating power reaches 100 watts between holding, common return end and by being connected with the second resistance R2 that operating power reaches 100 watts between holding, first resistance R1, second resistance R2 is located in box body, during detection, the detection current settings of earth resistance tester is 10 peaces, and early warning resistance is set as 0.5 ohm, earth resistance tester is successively connected to common return end and by between holding, common return end and warning are carried out detecting between holding thus are judged whether earth resistance tester normally works.
The utility model earth resistance tester point inspection device can carry out marginal testing for the conventional earth resistance tester in present manufacturing enterprise, adopt one to simulate disabling device to verify earth resistance tester, thus avoid instrument occur abnormal occurrence in daily production and application.This earth resistance tester point inspection device is through long investigation, in depth resolve the principle of work of earth resistance tester, technical characteristic, method of testing and relevant national metrological verification regulations, and basis in conjunction with the operability of instrument in routine use process is developed.This earth resistance tester point inspection device simple to operate easy to learn, during detection, need be only 10 peaces by the detection current settings of earth resistance tester, and early warning resistance is set as 0.5 ohm, then earth resistance tester is successively connected to common return end and by between holding, common return end and warning detect between holding, just can judge whether earth resistance tester normally works, operating personnel can complete the spot check work to earth resistance tester like a cork, and this earth resistance tester point inspection device not only can meet the spot check requirement in routine use, can also the warning function of validation test earth resistance tester exactly, can effectively to lose efficacy the risk brought by lowering apparatus, the normal function performance of earth resistance tester can be guaranteed, order of accuarcy and unfailing performance.The utility model achieves a kind of rational in infrastructure, simple to operation, detects accurately and reliably, can by detect guarantee earth resistance tester normal function performance, order of accuarcy and functional reliability earth resistance tester point inspection device.
