电蚊拍栅格残余电压检测方法差异探析及测试电路的设计

Analysis of Differences in Residual Voltage Detection Methods for Electric Mosquito Racket Grids and Design of Testing Circuits

灭虫器的特殊标准为GB 4706.76-2008《家用和类似用途电器的安全 灭虫器的特殊要求》,而其中第22.103条款即栅格残余电压的测试是电蚊拍产品中非常重要同时不合格率非常高的一个考核项目,本文主要根据灭虫器标准GB 4706.76第22.103条款,探讨该条款不同检测方法之间的结果差异,并结合相关的测试结果,分析导致不同测试结果最终数据差异的原因。同时根据已有测试方法中的难点设计一套用于检测检测1 s后电蚊拍栅格余电测试电路。

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 I second.
