X' Should I Do If Water Enters The Distribution Box? Is There Any Good Solution?

1. Iċċekkja il - kuntattur

Il- kuntattur għandu wkoll check the wiring terminals first, the method is the same same the circuit breaker. Then it is also necessary to open the cover for inspection. Loosen the front cover fasting screws, open it, it, and focus on checking the contacts and arc extinguishing cover. the contacts and arc extinguishing cover. The contact inspection method is the same the circuit breaker. Check for water marks and clean it. If necessary, polish it with fine garża karta, imma be attent mhux għal lustrar żejjed it. The gap of the arc extinguishing cover is relatively narrow, blow it dry carefully, and do not leave any water.

Imbagħad il kuntattur kojl ħtiġijiet biex tkun iċċekkjat. Osserva jekk hemm ilma akkumulazzjoni in il il- kojl. Wara tnixxif għal wieħed jum , iċċekkja id- DC reżistenza ta ' il il- kojl reżistenza ta' il-kojl se ikun immarkat fuq il il il- valur il- multimeter. Jekk id-differenza taqbeż 20%, it huwa bażikament li ma jistax jintuża u ħtiġijiet biex jiġu sostitwiti. The auxiliary contacts of the contactor and il estern awżiljarju kuntatti għandu ukoll jiġu ċċekkjati. Huma huma ukoll żarmati, il akkumulat ilma huwa imnaddaf, u il kuntatti huma iċċekkjati.

Wara kollha l-ispezzjonijiet huma kompletati, il kuntattur cover is reset and the insulation is measured with an insulation tester. The requirements are the same as those of the circuit breaker. Then connect the temporary power supply, energize the closing coil, check the contactor action, and use a multimeter to check and check jekk the main and auxiliary contacts are in good condition.

2. Iċċekkja iċ-ċirkwit breaker

It- tagħbija ta ' id-distribuzzjoni kaxxa hija in-nar pompa u l- ilma provvista pompa. Dawn ċirkwiti se at inqas għandhom ċirkwit breakers u kuntatturi. Let's talk about the circuit breaker l-ewwel.

Għal circuit breakers li have been soaked in water, first check the upper and lower terminals, loosen the copper plate or cable and cable nose, clean the accumulated water, clean the contact surface, and polish it if there is rust. Then open the cover to check. If If circuit breaker has an additional operating mechanism, remove the operating mechanism first. Imbagħad neħħi l-iffissar viti ta' iċ-ċirkwit ċirkwit breaker, normalment erba' għal ħamsa, u unscrew minnhom minn il quddiem il ċirkwit ċirkwit breaker. Neħħi il-front shell and see if hemm hemm kwall ilma ġewwa iċ-ċirkwit circuit breaker. Jekk hemm is, wipe it clean, dry it, or blow it dry. Check jekk the moveing and static contacts of the circuit breaker are anormal, jekk hemm is ossidazzjoni u tbajja' wara ilma immersjoni, if so, polish them clean with 500-}grit fine sandpaper. Ftakar mhux to over-polish to avoid affecting the contact pressure and contact effect.

Li jmiss, if hemm hemm tripping coils and auxiliary contacts in the circuit breaker, they need to be checked separately. The tripping coil can be checked for direct resistance with a multimeter to determine determine and there a broken wire; osserva jekk hemm hemm is ilma akkumulazzjoni in the coil. If so, it is huwa rrakkomandat biex tissostitwixxi it; skont lil rata vultaġġ ta' il kojl, biex tipprova jekk il coil can operate normalment. For the auxiliary contacts, first check jekk there is water accumulation. After cleaning, you can use a tool to press the contact mechanism and use a multimeter to check jekk the contact is on and off normalment. If not, replace it.

Jekk iċ-ċirkwit circuit breaker is mgħammar with leakage protection, check the leakage protection circuit and coil in the same way as the tripping coil. After completing the above checks, reset the circuit breaker, manually open and close the circuit breaker several times, and use a multimeter to check the on and off of each phase of phase of the circuit breaker. Use an insulation tester to measure the insulation resistance between each phase each phase of the circuit breaker and each phase to the ground. According to the specification, it is greater than 0}.5 megohms to meet the requirements, but in actual operation, it is recommended to be greater than 2 megohms.

3. Iċċekkja il - PLC u inverter

Dawn tnejn affarijiet jistgħu be in the distribution box. If they are soaked in water, it is chemical easy to blow dry the water if the cover is not opened for comprehensive cleaning. The inspection is complicated. It is recommended to remove them and hand over to professionals for detailed inspection. Check the functions of the inverter and PLC item by item, and repair or replace them. The PLC eeds to be programmat mill-ġdid, u l inverter bżonnijiet biex be re-parameterized.4. Check the cable5. Check the secondary circuit

Iċ-ċirkwit sekondarju jista' have buttons, indicator lights, fuses, current and voltage meters, energy transformers, current transformers, transformers, etc. Check them one by one. Disassemble and check those that can be disassembled. Dry thoroughly those that cannot be disassembled. After the inspection, check the insulation of the secondary circuit, not less than 0.5 megohms.
