家里安裝了幾個小型斷路器,其中有幾個是銜接UPS,服務(wù)器設(shè)備的,為什么一到晚上12點到2點左右,電流會忽然變的很大,導致銜接服務(wù)器設(shè)備的幾個斷路器跳閘,白天不會,并且也不是每天晚上都這樣,是為什么呢?電氣成套設(shè)備廠家給大家做一個分析解答!
There are several miniature circuit breakers installed at home, some of which are connected to ups and server equipment. Why does the current suddenly change a lot from 12:00 to 2:00 in the evening, causing several circuit breakers connected to server equipment to trip, not in the daytime, and not every night? Why? Electrical complete sets of equipment manufacturers to do an analysis!
檢查內(nèi)容有以下幾點,正常狀況下,假如設(shè)計沒問題是不會出現(xiàn)以上的那種狀況的,出現(xiàn)這種狀況的話有線路虛接的可能性大,建議盡量去查查線路。
Check the content of the following points, under normal conditions, if there is no problem with the design, it will not appear the above kind of situation, if there is such a situation, there is a possibility of virtual line connection, it is recommended to check the line as far as possible.
1、去檢查配電柜(配電柜、箱式變電站、配電箱)下面的用電設(shè)備,檢查是否有在事端時間段有大功率輸出。
1. Check the electrical equipment under the distribution cabinet (distribution cabinet, box type substation, distribution box), and check whether there is high power output during the incident period.
2、檢查配電柜(配電柜、箱式變電站、配電箱)內(nèi)部及到各用電設(shè)備的線路銜接,檢查是否有虛接現(xiàn)象。
2. Check the line connection inside the distribution cabinet (distribution cabinet, box type substation, distribution box) and to the electrical equipment, and check whether there is virtual connection.
3、調(diào)查在事端期間是否有人為因素(誤操作等)引起短路等。
3. Investigate whether human factors (misoperation, etc.) caused short circuit during the incident.
4、檢查用電設(shè)備(配電柜、箱式變電站、配電箱)是否有損壞(在晚上12點到2點這段時間正是用電低峰,線電壓比較高,假如設(shè)備本身在損壞邊際,如二極管等,在電壓到達一定程度的狀況下或許出現(xiàn)瞬間擊穿現(xiàn)象,然后引起短路)
4. Check whether the electrical equipment (distribution cabinet, box type substation and distribution box) is damaged (during the period from 12:00 to 2:00 p.m., the power consumption peak is low, and the line voltage is relatively high. If the equipment itself is at the edge of damage, such as diode, it may break down instantaneously when the voltage reaches a certain level, and then cause short circuit)
于配電箱跳閘的原因或許有以下原因:
As for the causes of distribution box tripping, there may be the following reasons:
1、檢查空氣開關(guān)是否損壞。
1. Check the air switch for damage.
2、檢查空氣開關(guān)接線是否正確。不正確并從頭接線。
2. Check whether the air switch wiring is correct. Incorrect and rewired from the beginning.
3、檢查空氣開關(guān)負荷側(cè)的線路絕緣,假如短路接地,需求排除故障后才能正常合閘。
3. Check the line insulation at the load side of the air switch. If the short circuit is grounded, the switch can be normally closed only after the fault is eliminated.
電氣成套設(shè)備公司提示:假如一送電就跳閘,闡明是線路接地短路了。
Electrical equipment company tips: if a power on the trip, clarify that the line is short circuit to ground.
