How to deal with the water ingress of the distribution box, and how to deal with the water ingress o

If the distribution box is flooded, the power should be turned off as soon as possible to prevent a short circuit from blowing up. Then use a hot air dryer to dry the various electrical switches, circuits and other components in the box one by one, and after ensuring that all the components are blown dry, energize and close each switch one by one for testing, which can basically be completely handled. Here's how:

1. Cut off the power supply (cut off the main power supply and send someone to guard it when the power is off) (do not use your hands when the power is off, use an insulating rod or dry wood, and wear insulating gloves, because there will often be a huge arc and an electric shock accident occurs).

2. Dry the energized part of the upper end of the main switch with a hair dryer.

3. Open the switch lid and dry them one by one. Power-on trial. Test whether the switch is damaged.

4. Build a rainproof shelter.

Turn off the power first, not ask questions!

Hee-hee!Then dry it, and if the test original is not damaged, you can continue to use it!

After the distribution cabinet is flooded, the equipment is dried according to the usual process 12. Line insulation resistance test;3. System component testing;4. Replacement of system components;4. No-load commissioning;5. System debugging or load operation can be solved.

However, according to this process, it is both time-consuming and costly, if you want to restore power quickly, you can use live cleaning technology to directly clean the flooded equipment, and directly carry out the withstand voltage test after cleaning, without waiting for the equipment to be completely dry to send power, this method is the fastest and most efficient.

If the meter box is flooded, the power should be turned off as soon as possible to prevent a short circuit from blowing up. After turning off the power, the water leakage should be accurately found and plugged. After ensuring that all components are blown or air-dried, they are powered on and each switch is closed one by one for testing to eliminate hidden dangers.

In addition, in the process of installing the meter box, the connection line and the distribution line should be connected into the lower bow line, and the line entering the meter box should have a waterproof bend, and an S bend should be formed to prevent water backflow.

Summary. How to deal with the leakage at the top of the distribution box: the water leakage treatment method at the top of the distribution box is that in the process of installing the meter box, the connection line and the distribution line should be connected into the lower bow line, and the line entering the meter box should have a waterproof bend, and an S bend should be formed to prevent water backflow.

How to deal with the leakage at the top of the distribution box: the water leakage treatment method at the top of the distribution box is to connect the connection line and the distribution line into the lower bow line during the leakage process of installing the meter box, and the mid-range line entering the meter box should have a waterproof bend, and also form an S bend to prevent water from backflowing back to the training.

On the line, water seeps into the tunnel, and seeps into the empty open along the line.

If the leak occurs on the pipe and pipe fitting joints, the staff first needs to close the pipe valve outside the electrical box. Next, the fitting should be disassembled for inspection, and if there is no damage, it can be filled with packing after wiping it clean, and then it can be re-tightened.

Here's how to deal with it:

1. Turn off the power immediately to prevent a short circuit from blowing up.

2. Use a hot air dryer to dry each electrical switch, circuit and other components in the box one by one, and after making sure that all components are dry, energize and close each switch one by one for testing.

3. After the test hood is normal, turn on the power supply.

How to prevent water ingress into the distribution box: You can add another layer of sealing strip to the edge of the door frame of the distribution box to prevent water from entering.

The distribution box is to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-enclosed metal cabinet or on a screen according to the requirements of electrical wiring, constituting a low-voltage power distribution device. During normal operation, the circuit can be turned on or off by manual or automatic switching. In case of failure or abnormal operation, the circuit is cut off or alarmed with the help of protective appliances.

The measuring instrument can be used to display various parameters in operation, and some electrical parameters can also be adjusted, and the deviation from the normal working state can be prompted or signaled. It is often used in various power generation, distribution and substations.

Many electricians generally reflect that when maintaining the distribution cabinet, they will find that there will be more or less dampness in the distribution cabinet, some of the distribution cabinet is particularly damp, the surrounding cables are covered by mildew, and the metal components in the distribution cabinet are also rusty, and there are often tripping situations, and some even cause fires.

In fact, the rust and mildew of the distribution cabinet is mostly caused by moisture, when it is found that there is a damp phenomenon, measures should be taken immediately to prevent moisture, and then I will share with you the effective method of dehumidification of the distribution cabinet.

An effective way to dehumidify the distribution cabinet:

1) Use the power outage to wipe the equipment and keep the distribution box clean.

2) Enclosed distribution cabinet. The ventilation windows and vents of the high-pressure chamber shall implement air filtration measures in accordance with the regulations. Keep high-pressure room air clean.

3) The cable trench, cable tunnel and cable hole under the distribution cabinet are waterproof sealed, and natural ventilation and moisture exhaust channels are installed to keep the air in the cable tunnel dry.

4) Outdoor power distribution cabinets can be equipped with rain rides.

5) Eliminate the defect of rain leakage on the top of the distribution cabinet in time.

6) The iron plate at the bottom of the closed bus bridge in the outlet is changed to a steel wire mesh plate, or a l00mm gap (close to the wall) is opened horizontally, and the rainwater can be discharged from the gap when it enters from the fixed steel plate of the outlet wall casing. No access to the control cabinet.

7) For the condensation condition that has already occurred and is more serious, it is recommended to use SPR-NL anti-condensation device or HK-Sepri-T overhead dehumidification system, which is automatically controlled according to humidity to remove moisture from the cabinet.

According to the size of the distribution box, a drainage dehumidification device can be installed in the distribution box, which is simple and convenient to install, and the water vapor in the cabinet can be directly discharged through the hose. SPR-CN-S1 smart dehumidifier is a drain type dehumidifier with a sensitive sensor that will automatically dehumidify once the humidity exceeds the set threshold.

Do a good job of sealing and moisture-proof to effectively prevent water vapor from entering the distribution box. It is mainly to inspect the parts with gaps such as incoming lines, outgoing lines, and distribution box doors, and apply sealant and styrofoam if necessary;

Active dehumidification in the distribution box, including better desiccant, active heating and insulation, active ventilation and dehumidification, etc.

1. The box body should be sealed, and there will be cable trenches under most distribution cabinets, so it should be sealed at the position of the middle partition.

2. It can be used in a live environment, and a heater or dehumidifier can be installed.

3. Do not live environment, can put condensation humidity resistor or desiccant.

Is the power off? I have been using it all the time, and the components inside are all heated, how can there be water vapor condensation? Don't be busy with power transmission, first use a heat gun, hair dryer or a small sun, dry the dew, and then you can send electricity, safety first, your power distribution cabinet is placed in the basement, like these days outside hot, indoor cold, if the power is cut off is the most likely to condensate, if not for maintenance, don't easily cut off the power, power off and then power, must be sent by multiple people, strictly abide by the power transmission manual.

The easiest way to do this is to install a dehumidifier in the cabinet.

A dehumidification device is installed in the distribution box.

Not very clear, you ask someone.
