How to solve the problem of tripping of electric floor heating

Electric underfloor heating tripped.

The solution to the problem is: the switch is turned on and trips immediately, it may be a short circuit or insulation problem, and the whole system needs to be checked to determine the cause of the failure. Seek professional maintenance personnel to overhaul the trip problem in time, and the problem can be solved.

If the power of the system overload electric floor heating exceeds the load of the power switch, the overload protector will be activated after the power is turned on, and then the circuit will be disconnected. In addition to design reasons, the following three factors can also lead to system overload: first, the selected power switch load is not suitable; Second, the power supply voltage is unstable;

The third is caused by the system starting current. Among them, the starting current will only appear when the self-limiting electric floor heating is heated.

The electric underfloor heating system of the body, which is determined by the nature of the self-limiting temperature heating material.

How to solve the tripping problem of electric floor heating? At present, there are two main solutions:1. Avoid the leakage protection switch, or use the air switch without the leakage protection switch, this method must ensure that the electric heating film floor heating is not grounded, and it is necessary to use a shake meter to measure whether the electric heating film floor heating has a grounding phenomenon, to ensure that there are no above problems, before replacing it with an air switch or adjusting the power cord of the electric heating film floor heating to skip the leakage protector, but there will be certain safety hazards in doing so; It is generally not recommended;

2. There is a senior electrical engineer in Shanghai, how did he help solve the problem of tripping some electric heating film floor heating, combined with his professional knowledge in practice, produced a small reactor, the role of this reactor is to reduce the leakage current, frequency conversion monitoring to compensate the current difference between the zero line of the live wire, to reduce the impact of leakage current on the leakage protection switch, but this reactor due to a certain limitation of power, can only be effective for the electric heating film floor heating within a certain area and power, If the electric heating film floor heating exceeds a certain area and power, this reactor will not be able to play a role, and therefore, this reactor is now discontinued because the market is relatively small!

If the tripping problem of electric heating film floor heating wants to be fundamentally solved, it is necessary to use the electric heating film heating system that can be safely grounded, the current market is that there are already domestic electric heating film manufacturers to produce electric heating film floor heating can be safely grounded, no matter what ground is laid, it will not have an impact on the leakage protection switch and cause tripping, this electric heating film has an outer packaging outside, which can protect the electric heating film and waterproof and damage-proof, and the aluminum foil shielding layer is added to the electric heating film inside, which can absorb the leakage current generated by the electric heating film. Then guide back to the zero line, so that the current value difference between the zero line of the live wire can be balanced, and the leakage protection switch is prevented from tripping;

The reason for the electric heater to trip after plugging for a while: the trip is caused by the leakage current caused by the poor insulation of the internal circuit of the heater to the ground. If the current at that time exceeds 25A, then the trip is the correct action of protection.

In this case, to replace the large switch, you must know whether your wiring can withstand more filial cracks. Because in the past, household load designs were designed according to 25A. The correct trip of the switch can only limit the load, not replace the big switch!

That creates a safety hazard. If the switch trips before the rated current is reached, it may be a quality problem or a wiring fault, the latter is quite common. Just tighten the wiring.

The former is replaced with a switch of the same specification. Huai Jue.

There is another situation of electric floor heating tripping, when the working power of electric floor heating exceeds the load of its air switch, it will also cause air opening tripping due to overload; In this case, you need to measure the power of the electric floor heating, and then replace the high-power air switch, which can solve the trip problem!

Of course, if the electric floor heating is damaged and tripped, then it cannot be solved! You can only find the damage point and replace the electric floor heating!

When the electric heating film floor heating is laid under the wooden floor or composite wood floor, there is no cement mortar layer and tile layer, and the distributed capacitance does not have the conditions for formation, so the wooden floor is laid with electric heating film floor heating, generally there will be no leakage current or very small, so it will not cause the action of the leakage protection switch; This can also explain the current market often seen South Korean electric heating film and the United States electric heating film rarely used in a large area of engineering installation, these electric heating film generally do not have outer packaging and shielding technology, this electric heating film is referred to as electric heating film bare film, that is, there is no protective outer packaging and shielding technology treated electric heating film, most of these films are sold and installed in the first home heating, sales generally require customers to use under the wooden floor floor, is to avoid the leakage current problem of electric heating film floor heating, Reduce the tripping phenomenon that occurs in the later stage;

What is going on with the old tripping of floor heating, the old tripping of floor heating electricity should be caused by excessive electrical load, first check whether there is a short circuit in the line, or the aging of the air switch.

Hello: 1, there are generally two reasons for floor heating tripping: overcurrent or short-circuit tripping; , leakage tripping.

2, be sure to pleaseQualified professional electricianInspections and repairs are carried out to determine the point of failure and solve the problem.

1. The power of the electric heater is too great, and the household voltage cannot withstand it. In this case, it is necessary to replace the electric heater with a lower wattage.

2. There are too many electrical appliances used at the same time as electric heating, resulting in unbearable household voltage. In this case, the use of electric heaters can be reduced while reducing the use of other electrical appliances.

3. The internal circuit of the electric heater is poorly insulated to the ground, resulting in leakage current. When the leakage current exceeds the rated residual operating current (generally 30 mA) of the leakage protection cover crack switch, the switch will trip. You need to find a maintenance master for repair.

4. Electric heating leakage. Check the leakage of electric heating and carry out maintenance.

Hello, the reasons for the tripping of floor heating may be: First, the selected power switch load is not suitable Second, the power supply voltage is unstable. First check whether there is a short circuit in the line, or the aging of the air switch.

Avoid the leakage protection switch, or use the air rush gas switch without the leakage protection switch, this method must ensure that the electric heating film floor heating is not grounded, you must first use a shake meter to measure whether the electric heating film floor heating has grounding phenomenon, to ensure that there are no above problems, before replacing it with an air switch or the power line of the electric heating film floor heating to skip the leakage protector, but there will be certain safety hazards in doing so; It is generally not recommended;
