Summer is the peak period of high voltage inverter failure, Elinker remind you should pay attention to the daily maintenance of inverter problem. First test installation temperature of the environment, clean the converter internal dust on a regular basis, make sure that cooling air way patency; Secondly, strengthen inspection, improve the inverter, motor and circuit of the surrounding environment; final inspection terminals are fastened to ensure correct and reliable connections every electrical circuit to prevent unnecessary downtime incidents.

Emergence of Terminal block greatly facilitates the connection of electronic components, in practice, terminal blocks, which can ensure a stable current and signal output, and can ensure the security of the entire line, in the converter industry received great acclaim.

Terminals of censorship, although vital, but maintenance of the converter must also take into account other aspects of the problem are as follows:

First, Routine inspection needs attention

1, the summer temperature is high, the ventilation of the inverter installation sites should be strengthened. Make sure that does not contain an excessive amount of dust in the ambient air, acids, salts, corrosive and explosive gases.
2, frequency must be kept clean and tidy, cleaned at any time according to the actual situation.
3, summer is the rainy season, should prevent the rain water into the converter within (such as rain-wind outlet into).
4, inverter filter should be cleaned once a week usually on the door if working conditions dust, cleaning intervals should be shortened according to the actual situation.
5, carefully monitor and record the frequency converter on the man-machine interface of the display parameters, unusual should reflect.

6, carefully monitor and record the frequency converter the ambient temperature of the room, the ambient temperature should be between-5 ℃ ~ 40℃. Phase-shifting transformer temperature should not exceed 130 degrees Celsius.
7, frequency converter must have good ventilation, lighting, ventilation and heat dissipation devices (such as air conditioning, through fan) works.
8, inverter in normal operation, a standard A4 paper should firmly adsorbed on the thickness of the door air inlet filter.

Second, inverter shutdown maintenance is required after project

1, check the inverter internal cable connections should be correct and reliable.
2, check the inverter Cabinet of all grounding should be reliable, no rust.
3, every six months (inner) fastening the inverter again internal cables connecting nut.
4, with a plastic nozzle vacuum cleaner to thoroughly clean the converter cabinets inside and outside to ensure no excessive dust around.
5, check the inverter room ventilation, lighting equipment, ensure the functioning of ventilation equipment.
6, after each maintenance inverter, carefully check for any missing screws and wires to prevent small inverter short circuit accident caused by metallic objects. Especially after major changes to the electrical circuit, ensure reliable electrical connector is connected correctly, to prevent the ' reverse power ' accident from happening.
