摘 要:為了克服現今繼電保護壓板隔離方法存在的不足,針對繼電保護壓板的特征設計了一種與其適配的夾具,利用Solidworks繪制了二次屏柜試驗端子隔離器的設計三維圖,并對其使用方法進行了闡述。經實際應用表明,提出的防繼電保護壓板誤分合夾具,可有效避免常規(guī)紅膠布隔離方法造成的浪費,保證保護壓板在投入或退出情況下的防誤分合,精密度高,安裝和拆卸簡單,且在使用過程中,誤操作率和脫落率為0%。
關鍵詞:繼電保護;硬壓板;防誤分合;夾具

Abstract: In order to overcome the shortcomings of the current relay protection plate isolation method, a clampfixture suitable for the characteristics of the relay protection plate is designed. Solidworks is used to draw a three-dimensional drawing of the design of the terminal isolator for the secondary panel test, and the use methodis described. Practical application shows that the anti-relay protection pressure plate mis-closing and clamping fixture can effectively avoid the waste caused by the conventional red tape isolation method, and ensurethat the protection pressure plate is protected against mis-opening and closing under the condition of input or withdrawal, high precision, simple installation
and disassembly, and the misoperation rate and drop-out rate are 0% during use.
Key words: relay protection; hard pressing plate; anti false opening and closing; clamp fixture
