What happens to the leakage protection skipping jump, the leakage protector trips and jumps half

LBQ- type leakage protector tester is mainly used to test the leakage action current, leakage non-action current and leakage action time of leakage protector. Both single-phase and three-phase leakage protectors can be tested.

Technical parameters: 1. Rated voltage: AC380V; ac220v；

2. Test line voltage: below AC250V;

3. There are 10 levels of leakage current in the binning MA;

4. Test leakage action time range: 0-799ms;

5. Leakage current accuracy: level 1;

6. Action time display accuracy: level;

7. Ambient temperature: 0 -40;

8. Relative humidity of the use environment: 85%;

9. Dimensions: 195 (length) 101 (width) 42 (depth);

Its test current is divided into 10 gears, namely: 15mA, 30mA, 50mA, 75mA, 100mA, 150mA, 200mA, 250mA, 300mA, 500mA. In the above case, first test with 10mA current, it should be empty and not operating, and there is no action time if it is not operating.

Then test with 30mA current, under normal circumstances, the air opening action (tripping), then the air opening action time is displayed, whether the action time is less than, if it is less, it means that the air opening is normal, it is good, and it can be used. If it is given 30mA current and does not work, it means that there is a problem with this empty opening, and it is recommended to replace it. In terms of use skills, one thing should be noted, the normal use is in the open lower contact with leakage protection function, a live wire and ground wire two-point test, if there is no ground wire on the site, you can also use the neutral wire instead of the ground wire, which is also possible.

Warranty Leakage:1Select a capacity greater than the upper level, 2The leakage tripping mechanism is aging and sluggish.

Hello, it is a pleasure to serve you that the leakage protector trips half of the first reason: because the heavy load exceeds the rated load, it is an overload protection trip. The second reason:

Because some electrical appliances have grounding phenomenon, you can gradually plug in or open the electrical appliances when you open a certain electrical appliance, you must first check whether there is a suspicion of leakage, or high-power electrical appliances, the load has accumulated to exceed the rated load. The third reason: check whether there is leakage can turn off or unplug other electrical appliances, open this piece separately, if it is turned on normally, it means that it does not leak, if it will also trip, it means that the problem is on this equipment.

The fourth reason: if there is no leakage equipment, it is a load problem, you can first see how big your air opening is (also pay attention to the allowable load of the meter), and then convert the total power of the electric land in use when you turn on the use, (refrigerator and air conditioner to the compressor starts whether the power is calculated), if the overload is indeed unable to adjust and avoid, it is necessary to consider the problem of meter expansion and air replacement. The fifth reason:

If none of the above problems are the above, then change one or a new empty open with the same shirt to see if it is caused by empty opening failure or allergies. If you don't understand, it's safer to find a professional, after all, electricity is very dangerous to use.

The first reason: because the heavy load exceeds the rated load, it belongs to the overload protection trip;

The second reason: because some electrical appliances have grounding phenomenon and trip due to leakage protection;

You can gradually plug in or turn on the electrical appliances, when opening the shield of a certain electrical appliance to trip, you must first check whether there is a suspicion of leakage, or high-power electrical appliances, the load has accumulated to exceed the rated load;

The third reason: check whether there is leakage can turn off or unplug other electrical appliances, just open this one, if it is turned on normally, it means that it does not leak, if it will also trip, it means that the problem is on this equipment;

The fourth reason: if there is no leakage equipment, it is a load problem, you can first see how big your air opening is (also pay attention to the allowable load of the meter), and then convert the total power of the electrical appliances you turn on in use, (refrigerators and air conditioners are calculated by whether the compressor starts), if it is indeed overloaded, it is impossible to adjust and avoid, it is necessary to consider the problem of meter expansion and air replacement.

Leakage protector, referred to as leakage switch, also known as leakage circuit breaker, is mainly used in the event of leakage failure of equipment and personal shock protection with fatal danger, with overload and short circuit protection function, can be used to protect the overload and short circuit of the line or motor, and can also be used as an infrequent conversion of the line under normal circumstances.

Why does the leakage protector jump once a day pro, hello! 1. Poor installation: If the terminal post is not firmly connected during installation, it will often lead to heating and oxidation of the terminal post for a long time, so that the wire insulation layer will be burned and called rubber coke, and accompanied by the chain smell of ignition and rubber and plastic burning, resulting in undervoltage of the line and tripping the leakage protector. 2. When the leakage protector itself is a problem, the user should try to buy it from a reputable designated manufacturer or store, and do not buy the "three no" leakage protector from some self-employed individuals at a low price, which often outweighs the loss.

Hope it helps!

Summary. 1.The installation of the leakage protector is not in place, so that it has poor contact.

2.When purchasing leakage protectors, they did not pay attention to their quality.

3.The leakage protector does not match the load.

There is a leakage or short circuit in the line.

4.When the power supply comes in, the voltage is too high.

What is the reason why the leakage protector keeps jumping?

1.The installation of this protector is not in place, so that it has poor contact. 2.

When purchasing leakage protectors, they did not pay attention to their quality. 3.The leakage protector does not match the load.

There is a leakage or short circuit in the line. Frontboard 4When the power supply comes in, the voltage is too high.

It jumps from time to time, and I can't find the reason, what's going on, and the leakage protector has just been replaced.

It also tripped before changing to a new one, right?

I didn't jump before, so I jumped after changing, and I used a second-hand freezer after changing.

And always jumping at night.

That problem should be on the freezer, don't try it with the freezer.

If it's not the blame freezer, how do you find the reason.

It's either the freezer or the new leakage protector.

Cause analysis:1The main function of leakage protection is to solve the problem of leakage

Once there is a current loss, such as an electric shock to the human body, when the current flows to the ground through the human body, it generally exceeds 30 milliamperes, and the leakage protector will work to cut off the power supply, so as to eliminate the current from harming the human body. Therefore, unreasonable wires and incorrect convergence of neutral wires will lead to leakage protection actions, so do not use leakage switches as master switches, and it is recommended to use general air switches for master switches.

2.Do not let the lighting circuit and the socket circuit mix, so that the leakage switch of the socket circuit will be turned on and the leakage protection switch will trip.

3.General concept: Generally, it is better to install an air switch at the outlet end of the meter, because the distance of the wire is relatively far, and the failure rate of the leakage switch will be relatively increased, which may be caused by the wire.

It is better to install the leakage switch before using the equipment. The difference between the two codes is that the air switch will act if its rated current is exceeded, while the leakage switch will trip if it exceeds its rated current or leakage.

1.When there is leakage or electric shock in the protected circuit (that is, a small current greater than 15 mA and less than 30 mA is generated between the protected circuit and the earth), the leakage protector (leakage protection) will trip and trip.

2.When there is a short circuit between the phase wire and the phase wire or between the phase wire and the neutral wire (load short circuit), the leakage protector (short circuit protection) will trip only when the short circuit current is greater than or equal to the open circuit current set by the protector.

3.The current intensity of the tripping set for this short-circuit protection is very large compared to the current intensity set for the leakage protection. When the fuse blowing current is much less than the breaking current set by the protector, the leakage protector will not trip but burn the fuse.

There are several possibilities: first, it may be that the post-stage leakage protector is greater than the front-stage leakage protector, resulting in the post-stage protector not tripping and the front-stage tripping; Second, it may be that the post-stage leakage protector is damaged, resulting in protection failure; Third, it may be that the power of the pre-stage leakage protector is too small, and the power consumption of the post-stage is greater than the rated current that the pre-stage protector can withstand, which will cause the pre-stage protector to trip. In general, the third possibility is greater, in the case of ensuring the normal of the post-stage leakage protector, you may wish to adjust the pre-stage leakage protector appropriately.
