Analysis of Differences in Residual Voltage Detection Methods for Electric Mosquito Racket Grids and Design of Testing Circuits
The special standard for electric mosquito racket is GB 4706.76-2008"Special requirements for the safety of insecticides for household and similar electrical appliances",and clause 22.103,which tests the residual voltage of the grid,is a very important assessment item in electric mosquito racket products with a very high failure rate.This article mainly explores the differences in results between different detection methods according to clause 22.103 of GB 4706.76,and combines relevant test results,Analyze the reasons that lead to differences in the final data of different test results.At the same time,based on the difficulties in existing testing methods,design a set of residual electricity testing circuits for detecting the voltage of the grid after disconnecting the power for 1 second.
