電氣成套設(shè)備的使用避免不了問題的出現(xiàn)，提前做好預(yù)防工作有利于減少問題的出現(xiàn)，我們需要知道有哪些故障問題會(huì)出現(xiàn)，比如電氣成套設(shè)備越級(jí)跳閘的主要情況如何？

　　The use of electrical complete equipment can not avoid the emergence of problems, do a good job of prevention in advance to reduce the emergence of problems, we need to know what fault problems will appear, such as the main situation of electrical complete equipment trip?

　　主開關(guān)負(fù)載容量小于分開關(guān)負(fù)載總和的容量；主開關(guān)有漏電保護(hù)裝置然而分開關(guān)沒有，當(dāng)用電器漏電大于等于30毫安時(shí)主開關(guān)跳閘；兩級(jí)電氣成套設(shè)備保護(hù)不匹配，盡量使用同的電氣成套設(shè)備；經(jīng)常帶負(fù)荷操作主開關(guān)導(dǎo)致觸電碳化接觸不良后電阻增大電流升高發(fā)熱跳閘；下級(jí)電氣成套設(shè)備配置的保護(hù)無法正確判斷故障；電氣成套設(shè)備老化導(dǎo)致分勵(lì)脫扣時(shí)間變長，要更換一個(gè)分勵(lì)脫扣時(shí)間小于上一級(jí)開關(guān)的分開關(guān)。

　　The load capacity of the main switch is less than the total load capacity of the separate switches. The main switch has leakage protection device but not separated off, when the use of electrical leakage is greater than or equal to 30 ma when the main switch trip; Two levels of complete electrical equipment protection does not match, try to use the same brand of complete electrical equipment; Often with load operation of the main switch lead to electric carbonization contact poor resistance increases current increases heat trip; Failure can not be correctly judged by the protection of subordinate complete electrical equipment configuration; The aging of the complete electrical equipment causes the shunt trip time to be longer. Replace a shunt trip whose time is shorter than the split switch of the previous level.

　　如發(fā)生上級(jí)電氣成套設(shè)備越級(jí)跳閘，若查明有分路保護(hù)動(dòng)作，但該分路電氣成套設(shè)備未跳閘，則分?jǐn)嘣摷?jí)電氣成套設(shè)備，然后恢復(fù)上級(jí)電氣成套設(shè)備；若查明各分路保護(hù)均未動(dòng)作，則應(yīng)檢查停電范圍內(nèi)設(shè)備有無故障，若無故障可合上上級(jí)電氣成套設(shè)備，并逐一試送各分路電氣成套設(shè)備。當(dāng)送到某一分路時(shí)電源電氣成套設(shè)備又再跳閘，則可判明該電氣成套設(shè)備為故障電氣成套設(shè)備，可對(duì)該線路進(jìn)行隔離維修更換。

　　In case of grade-exceeding trip of superior complete electrical equipment, if it is found that there is shunt protection action, but the shunt complete electrical equipment does not trip, the electrical complete set of the same level shall be cut off, and then the superior complete electrical equipment shall be restored; If it is found that none of the shunt protection works, it should be checked that there is no fault within the scope of power failure. If there is no fault, the superior electrical complete set of equipment can be closed and each shunt complete set of electrical equipment can be tried one by one. When the power electrical complete set of equipment is sent to a branch and then trips again, it can be determined that the electrical complete set of equipment is faulty electrical complete set of equipment, and the line can be isolated, repaired and replaced.

　　電氣成套設(shè)備要跳閘須符合兩個(gè)條件，一是故障電流大小達(dá)到設(shè)定值，二是故障電流持續(xù)時(shí)間達(dá)到設(shè)定的時(shí)間長度，所以要確保電氣成套設(shè)備不越級(jí)跳閘須在電流設(shè)定值和時(shí)間設(shè)定值上配合好。要確保不越級(jí)跳閘須用繼保設(shè)備測試電氣成套設(shè)備的實(shí)際動(dòng)作時(shí)間總長，用實(shí)際試驗(yàn)結(jié)果的時(shí)間長度來確保配合的正確。

　　Tripping of complete electrical equipment must meet two conditions, one is the fault current reaches the set value, the other is the fault current duration reaches the set time length, so to ensure that the complete electrical equipment does not skip the trip, it must cooperate well in the current set value and time set value. To ensure that there is no leap-step trip, it is necessary to test the total actual operation time of complete electrical equipment with follow-up equipment, and ensure the correct coordination with the time length of actual test results.
