Low-voltage current wireless checking instrument

Abstract

The invention discloses a low-voltage current wireless checking instrument. The instrument includes a current detection clamp. A clamp holder and a display screen are arranged on the two ends of a housing of the current detection clamp. A detection module for receiving clamp holder detection signals is arranged in the housing, and is electrically connected to the display screen through a signal wire. The structural characteristics are that a wireless transmit-receive module is arranged in the housing, the signal input end of the wireless transmit-receive module is in parallel connection with the signal wire through a data line, the output end of the wireless transmit-receive module is electrically connected to a signal antenna, a battery for supplying power to the detection module and the wireless transmit-receive module is also arranged in the housing, the instrument further includes a host that wirelessly communicates with the wireless transmit-receive module, and the signal end of the host is electrically connected to a host antenna. The advantages and beneficial effects are that the instrument has a reasonable structure, can assist in detecting currents of lines in many positions at the same time, is easy to operate, is convenient for detection, is labor-saving and time-saving, can quickly determine a detection result, only needs one person to operate, and enables the detection efficiency to be improved.

Description

technical field [0001] The invention relates to a low-voltage current wireless calibration instrument. Background technique [0002] Electricity consumption inspection is a necessary activity organized by power supply enterprises. The traditional inspection method is to refer to the line loss of the entire line, combined with the on-site inspection of the metering device. With the increase of electricity customers, the wiring of low-voltage lines is becoming more and more complicated. The increase in safety and direct burial of cables increases the difficulty of power inspection. Therefore, after determining the possibility of electricity theft in a low-voltage line, measure the line loss of each phase in sections, and then gradually narrow the scope to enhance the specificity of the inspection object. Sex is especially necessary. [0003] At present, the most direct method for on-site inspection of low-voltage lines is to compare the current of the main line with ...

Problems solved by technology

[0003] At present, the most direct method for on-site inspection of low-voltage lines is to compare the current of the main line with the sum of the currents of each branch line to check whether there is any electricity theft such as privately connected lines. Due to the real-time and random nature of line loads, The measured value of time has reference significance. The traditional verification method is to measure with clamp ammeters by multiple people at different places at the same time, and use mobile phones to communicate and confirm, which is cumbersome and time-consuming
