產(chǎn)品概述：

隨著國(guó)網(wǎng)檢驗(yàn)日趨嚴(yán)苛，同時(shí)各種誤操作層出不窮，所以為了解決現(xiàn)有產(chǎn)品五防誤操作問題(即當(dāng)斷路器機(jī)構(gòu)合閘后，在擋住隔離主軸失效的情況下手柄插入隔離操作孔可以強(qiáng)行斷開隔離開關(guān)造成嚴(yán)重安全隱患)，特改進(jìn)了此斷路器和隔離機(jī)構(gòu)硬連鎖方案，真正達(dá)到了“硬”連鎖要求。

With the increasingly strict inspection of the State Grid, and at the same time various misoperations emerge endlessly, in order to solve the problem of five anti-misoperation of existing products (that is, when the circuit breaker mechanism is closed, the handle can be inserted into the isolation operation hole in the case of blocking the failure of the isolation spindle and can forcibly disconnect the disconnector and cause serious safety hazards), the hard chain scheme of this circuit breaker and isolation mechanism is specially improved, and the "hard" chain requirements are truly met.
