Problems solved by technology

[0002] The prepaid circuit breaker has large inlet and outlet holes, and the sealing is not good, especially for some humid and rainy areas in the south. During the use of the prepaid circuit breaker, that is, the charge control switch, the prepaid circuit breaker will trip due to rainwater or even continue to trip repeatedly. Closing phenomenon, resulting in power outage or continuous power outage and recovery, affecting the normal use of electricity of users and even damage to indoor electrical appliances of users, resulting in more complaints from users and certain economic losses
[0003] In order to solve the quality of the cost control switch itself and the matching between the cost control switch and the electric energy meters of different manufacturers, the existing technology is to manually bring the charge control switch to the site and directly match it with the electric energy meter, but the accuracy of manual matching is low. Low efficiency, poor compatibility, high cost

Abstract

The invention provides a test method and system for a fee-controlled switch, which integrates a program-controlled constant voltage source and an electric energy meter into the test system to realize the functions of bidirectional collection and bidirectional comparison of test data during the test process, that is, the PLC control system collects the electric energy meter The middle detection data and voltage acquisition module collects the test data of the product under test, and compares the two collected data through the PLC control system, and the results are consistent and judged to be a good product. Compared with the traditional one-way data collection and comparison, this detection method has more accurate measurement results and higher product quality. And through the innovative design of the actuator and test device in the mechanical device, the compatibility of 4 specifications of products from multiple manufacturers has been realized.

Description

technical field [0001] The invention relates to the technical field of automatic detection of the matching between a charge control switch product and an electric energy meter in a smart grid, in particular to a test method and system for a charge control switch. Background technique [0002] The prepaid circuit breaker has large inlet and outlet holes, and the sealing is not good, especially for some humid and rainy areas in the south. During the use of the prepaid circuit breaker, that is, the charge control switch, the prepaid circuit breaker will trip due to rainwater or even continue to trip repeatedly. Closing phenomenon, leading to power outage or continuous power outage and recovery, affecting the normal power consumption of users and even damage to the user's indoor electrical appliances, resulting in more complaints from users and certain economic losses. [0003] In order to solve the quality of the cost control switch itself and the matching between the cost cont...
