Can the DC screen open the rear cabinet door with electricity?

The DC screen is electrified, and the rear cabinet door can also be opened, but if it is repaired or maintained, it is best to turn off the power supply, which is the safest, and it will not damage other equipment.

The DC screen is not allowed to open the rear frame door when it is electrified, this is unsafe, and the line is more complicated.

If there is electricity, you can't open the rear cabinet door directly, so it's relatively dangerous, so it's recommended to protect it.

The DC screen should not be able to be opened after the power is not able to be opened, so it should not be possible, this should not be easy to open the rear cabinet door, unless you cut off the power supply.

The DC screen should also be able to open the rear cabinet door when it is charged, which should be able to be used as long as you don't touch this, or there is no reaction in the back.

Theoretically, the back door should not be opened with electricity at any time. This is a non-compliant operation.

Yes, it is the failure of the relay protection, you see if the cabinet door is opened, whether the row of DC switches inside is jumped, if not, see if the relay contact wire is loose, otherwise the board is broken.

Can the current screen open the rear cabinet door when it is live? For the sake of safety, it is best to cut off the power supply and then open the cabinet door, so that it is safer.

Can the DC screen open the rear cabinet door with electricity? I don't think there's anything going on with the cabinet door when the DC screen is opened. That's just a panel, the electrical components are all in it, and he's not high-voltage.

Can the DC screen open the rear cabinet door with electricity? I think that when the DC screen is electrified, it is best not to open the rear cabinet door, which is very dangerous.

Well, if you want to open the rear cabinet door and have to turn off the power, everything is uninterrupted, or don't disassemble it casually.

If it is a professional electrical worker, the low-voltage distribution cabinet can open the door to read the meter when it is running.

I don't know what kind of cabinet such a cabinet is, please follow the instructions in the operation line. Distribution cabinets with different voltages should have different operating specifications.

If you say this kind of thing, you can open the door of this cabinet, and this myth has nothing to do with it, this can be opened.

It is best not to open the door of the rear cabinet when it is charged, if you have to open this door, you can turn off the power first and then turn it back on.

If it is live, it cannot be operated, and it needs to be powered off before it can be operated.

The DC screen cannot be opened when the TV cannot open the back door, but it cannot be opened when there is electricity.

If there is electricity, it is best not to open the rear cabinet door, which is prone to electric shock.

Can 16 bottles be charged to open the rear cabinet door? I think Liu Ping can go and open the back cabinet door with a TV, I think of course it is.

Sun Luping can't open the rear cabinet door with electric potential.

The DC screen with the TV can not open the rear cabinet door, we should turn off the power to work.

Yes, there is no problem, the DC live one can open the rear cabinet door.

This should be a compressor model, and the model of this compressor is still relatively ordinary, and a common model can achieve a very good effect.

When pouring the liquid in a jar of bai.

du, the label is not to the palm of the hand [label zhi is corroded] dao2, the test tube after the heated version is directly placed in the real power.

On the examination table, the test tube was suddenly cold and burst

3. There is water on the outer wall of the heated test tube [test tube rupture].

4. Put the beaker directly on the flame of the alcohol lamp to heat [the beaker is heated unevenly, and the bottom of the beaker is broken].

(1) When heating the liquid in the test tube, place the mouth of the test tube facing the person. Consequences: Liquid spills and hurts.

2) Freshly heated test tubes, rinse immediately with cold water. Consequences: The test tube bursts.

What is the difference between reactor speed regulation and autotransformer speed regulation. Hardware problems in the discipline of home appliance science and engineering. According to your description, the biggest difference between them is:

A transformer has two windings, primary and secondary, with a total of four terminals (even an autotransformer has three terminals), whereas a reactor has only one winding, two terminals. Secondly, the two are used for different purposes: transformers are used to change the AC voltage (up or down), while reactors are only used to step down or ballast.

1. The total power is 10,000 watts (10 kilowatts), 380 volts three-phase power transmission, and 16 square copper wires can be selected (when ensuring that the voltage drop does not exceed 5%, the maximum can drive 12 kilowatts).

2. If it is a 220 volt single-phase transmission, the load capacity of the 16 square copper wire is only 2.5 million watts (if the transmission voltage can be appropriately increased, the load capacity can increase linearly).
