電阻測(cè)試法 :
Resistance testing method:
利用萬(wàn)用表的電阻檔測(cè)量電機(jī)、線(xiàn)路、觸頭等是否符合使用標(biāo)稱(chēng)值以及是否通斷。
Use the resistance range of a multimeter to measure whether the motor, circuit, contacts, etc. meet the nominal values and whether they are open or closed.
使用兆歐表測(cè)量相與相、相與地之間的絕緣電阻,確保絕緣性能良好。
Use a megohmmeter to measure the insulation resistance between phases and ground to ensure good insulation performance.
電壓測(cè)試法 :
Voltage testing method:
利用萬(wàn)用表測(cè)量電路中的電壓值,包括電源電壓、負(fù)載電壓及開(kāi)路電壓,以判斷電路是否正常。
Use a multimeter to measure the voltage values in the circuit, including power supply voltage, load voltage, and open circuit voltage, to determine if the circuit is functioning properly.
機(jī)械檢測(cè) :
Mechanical inspection:
通過(guò)觸摸電氣設(shè)備外殼的振動(dòng)和溫度,粗略判斷設(shè)備的運(yùn)行工況是否正常。
Roughly determine whether the operating conditions of the equipment are normal by touching the vibration and temperature of the electrical equipment casing.
檢查機(jī)械部件的安裝牢固性、螺絲緊固情況以及外觀(guān),確保機(jī)械系統(tǒng)無(wú)故障。
Check the installation firmness, screw fastening, and appearance of mechanical components to ensure that the mechanical system is fault free.
靜態(tài)與動(dòng)態(tài)檢測(cè) :
Static and dynamic detection:
靜態(tài)檢測(cè):在設(shè)備不通電的情況下,檢查外部部件如開(kāi)關(guān)、按鈕、插口及指示燈的工作情況。
Static detection: Check the working condition of external components such as switches, buttons, sockets, and indicator lights when the device is not powered on.
動(dòng)態(tài)檢測(cè):在設(shè)備通電后,進(jìn)行各項(xiàng)功能的調(diào)試和檢查,觀(guān)察是否有異?,F(xiàn)象。
Dynamic detection: After the device is powered on, perform debugging and inspection of various functions, and observe whether there are any abnormal phenomena.
先簡(jiǎn)單后復(fù)雜 :
Simple first, then complex:
先處理簡(jiǎn)單、直觀(guān)、常見(jiàn)的故障,再處理復(fù)雜、難度較高的故障,以提高維修效率。
First deal with simple, intuitive, and common faults, and then deal with complex and difficult faults to improve maintenance efficiency.
先外部后內(nèi)部 :
First external, then internal:
先檢查外部部件,如開(kāi)關(guān)、按鈕等,再拆卸內(nèi)部設(shè)備進(jìn)行檢修,以減少不必要的拆卸。
First inspect external components such as switches, buttons, etc., and then disassemble internal equipment for maintenance to reduce unnecessary disassembly.
接地檢查 :
Grounding inspection:
檢查主要元器件的接地情況,確保斷路器、真空接觸器、電容器、電抗器等設(shè)備的接地良好。
Check the grounding status of the main components to ensure good grounding of equipment such as circuit breakers, vacuum contactors, capacitors, and reactors.
元器件檢查 :
Component inspection:
檢查各元器件的安裝牢固性、螺絲緊固情況以及外觀(guān),確保無(wú)損壞或老化現(xiàn)象。
Check the installation firmness, screw fastening, and appearance of each component to ensure no damage or aging.
短路檢查 :
Short circuit inspection:
檢查電路中是否存在短路現(xiàn)象,確保接線(xiàn)正確、無(wú)裸露導(dǎo)線(xiàn)。
Check for short circuits in the circuit, ensuring correct wiring and no exposed wires.
功能測(cè)試 :
Functional testing:
按照?qǐng)D紙及說(shuō)明書(shū)進(jìn)行各項(xiàng)操作,行正常啟停機(jī)操作,再觀(guān)察各項(xiàng)故障保護(hù)動(dòng)作是否正常。
Perform various operations according to the drawings and instructions, first perform normal start stop operations, and then observe whether various fault protection actions are normal.
