Abstract

The invention relates to a portable electric energy measuring terminal comprehensive calibration instrument on site. The calibration instrument comprises an operation processor (1), an operation processor (2), a voltage sampling module, a current sampling module, an active and reactive power pulse input module, an access device (AD) converter, a displayer, a keyboard, a sampling switching module and a gain amplification module. The detector further comprises an on-off output module, a control detection input module, a carrier communication module, an active and reactive power pulse output module, and the control detection module is used for calculating and controlling the power parameter. The operation processor (1) is connected on the pulse output module and the on-off output module through an output switching module, the pulse output module is used for measuring and detecting the instrument with higher accuracy, the on-off output module is used for controlling the signal output and the on-off input of a device to be detected, the carrier communication module is used for completing the detection of the infrared and the carrier communication with the help of an infrared communication interface. A problem that the calibration function of the prior electric energy measuring device calibration instrument on site is single is solved.

Description

technical field [0001] The invention relates to a portable on-site comprehensive calibrator for electric energy metering terminals. Background technique [0002] With the rapid development of the national economy, the improvement of people's living standards, and the rapid development of the regional economy, the needs of electricity customers can no longer be satisfied by "lighting up with electricity", but "safety in electricity use, power supply Reliable, high-quality power, efficient work, reasonable charges, and thoughtful service.” At present, the service level of the electric power service market still has a big gap with the economic development and customer needs, and many needs of customers cannot be met or well met. Customer needs determine the direction of market development, so the current potential demand for high-quality, efficient, and thoughtful power technology services is very large and very strong. [0003] The current on-site calibrator for electric ene...
