Problems solved by technology

The existing protection verification device is bulky and the wiring is complicated. From the time the protection personnel receive the dispatching order to the completion of the protection device inspection, it takes 2 people to operate, and the working time is about 2 to 3 hours, resulting in a long power outage. The turbulence leads to a decrease in the accuracy of the calibration device and inaccurate test results

Abstract

The invention discloses a portable power protection verification device. The device comprises a host body, and the host body is provided with a host starting key, a regulation knob, a current displayand a voltage display. Binding posts are arranged at the lower end of the host body. A filtering adjustment module, a voltage regulation current-limiting module and a current transformer are integrated in the host body. The current output end of the voltage regulation current-limiting module is connected with the current input end of the regulation knob. The portable power protection verificationdevice brings convenience to carrying and use when a user goes out, meanwhile, the phenomenon that the precision of the verification device is reduced due to jolting is effectively avoided, the working efficiency is improved, the device is convenient to hang and carry due to a hanging buckle and a holding soft belt, the use convenience is improved, an isolation transformer enables the output voltage of the current loop to be smaller than the safety voltage of a human body, and then the safety of electricity utilization is guaranteed.

Description

technical field [0001] The invention relates to the technical field of power maintenance, in particular to a portable power protection and calibration device. Background technique [0002] With the improvement of urban modernization, the electricity load continues to rise. In order to ensure the safe operation of the power grid and the electricity demand of urban and rural residents, 100% guarantee of high-quality services and reducing the average power outage time of customers has become a key task. The existing protection verification device is bulky and the wiring is complicated. From the time the protection personnel receive the dispatching order to the completion of the protection device inspection, it takes 2 people to operate, and the working time is about 2 to 3 hours, resulting in a long power outage. The turbulence reduces the accuracy of the calibration device and the test results are inaccurate. Contents of the invention [0003] The technical problem to be so...
