One line controls two boilers, why does one wire heat up and the other doesn t?

One wire controls two pots, why does one heat? One doesn't send? Because a boiler takes a long time, and the power is large and the power is small, there must be a red furnace boiler with a long time, and there is also a boiler with a short time, there must be a difference, the work is separated, and it should also be considered, so one develops, one does not develop, that is, it depends on your working time for a long time, the time of the boiler and the circuit circuit to be checked.

First of all, check the line, if there is no problem with the line, maybe, the power of the two boilers is not the same, the power is easy to heat up, and the power is not easy to heat up.

It must be one thick and one thin, or the material of the two wires is different. In the line, the two wires in parallel with the power supply must be of the same thickness and the same material, otherwise the thin one is easy to generate heat when there is a high-power electrical appliance to use electricity, forming a bottleneck of power supply and wasting materials.

Under the same conditions of the operating environment, the wire that does not heat up is enough (thick), the capacity is enough, and the wire that heats up is not enough capacity and thick enough, and the other reason is that the wire material is problematic.

It is necessary to further judge which cause and find a way to solve the problem of wire heating.

One is the main line, two branch lines, all the current passes through the main line, and the main line current intensity is2 times the branch line, according to the formula w=i 2rt, the main line will heat up severely, the branch line will not.

Check whether the wire circuit is damaged first If you confirm that the circuit is in good condition, check whether the boiler itself is in good condition, basically these two places, there will be no problems in other places, this is my suggestion for your reference.

That shows that the power of these two boilers is different, and the power is high.

It should be that the thickness of the two lines is different.

The boiler can't be thin, and it's easy to damage the boiler by talking with iron and crutches.

If this happens in the boiler room and the cables continue to heat, it may be because your load is too high.

It is normal for the cable to heat up. As long as its temperature is within the range. So, no problem, we can test whether the three-phase current is balanced?

After a while, in fact, 5000 to the motor and 70 cable to run the power line, why does the cable heat up during the period? In fact, the frequent line should be thin and should be a 95 square cable line.

The electric boiler is a pure resistance circuit, and the rated heat generated is q=pt=80000w*1s=80000j. This electric boiler produces a rated heat of 80,000 joules per second.

There are several cases in which it cannot be automatically closed:

If it can be closed manually, indicating that there is no problem with the inspection hall control loop of the control relay, then the problem lies with the detection device (temperature sensor control loop);

If it can't be closed manually, then the relay is broken, and there is a problem with the pin base or the relay hidden control loop.

The relay cannot control the heating element because the relay power is relatively small. The control heating element is controlled by a contactor in the automatic control and starting system.

Reason why the contactor that controls the heating element does not engage:

1. If the voltage is too low, check whether the power supply voltage reaches more than 85% of the rated voltage, which is the minimum requirement for the contactor coil suction voltage.

2. The control loop is quietly excavated, such as thermal relay action, and the normally closed point is opened; Stop pressing the button and the closing point is not closed properly; Locked with other equipment, it does not have the conditions for starting; Control fuse or control switch disconnection, etc.

3. The contactor coil burns out.

4. The contactor coil is broken, 5. Check whether the applicable voltage level of the contactor coil is dissipated with the power supply, and see whether the voltage is 220V or 380V

6. Check whether the power switch is turned on and whether the starting circuit is open.

It should be that the switch is in poor contact, and the poor contact will cause the switch to heat up, and it may also cause a fire, so change the switch quickly.

The calorific value of a ton of boiler is 600,000 kcal h, and 860 kcal h is equivalent to the heat generation of kilowatt-hour (excluding heat conversion rate) produced by one kilowatt-hour of electrical energy

Compared with the point heating film, the energy-saving is the heating cable, and the most energy-saving is the carbon crystal floor heating. If you have to use electric floor heating, it is not recommended that you use electric heating film, the life of electric heating film is not very ideal. I feel like you might as well use a heat pump, which is much better than electric underfloor heating.

I don't know where you want this electric floor heating to be used, is it the second floor? But the boiler on the first floor of your first floor is really small, and you need to use at least 1200W. If there is no external wall insulation, it will be larger.

A minimum of 12kw electric boiler (100-120 square meters) is required
