What is the system structure of the induction coil?

The induction coil system, also known as the closed-circuit electromagnetic induction collective hearing aid system, is the earliest collective hearing aid technology. The hearing aid system consists of a main console, a toroidal induction coil pre-positioned in classrooms, homes and other indoor locations, and a separate hearing aid. It can transmit the voice signal of external wired microphone or FM wireless microphone, as well as the audio signal of recorder, electronic organ and TV.

What is the principle of induction coil?

Induction coil According to the principle of electromagnetism, we know that when a long straight wire has an electric current passing through it, there will be magnetic lines of force around it. According to the right-hand law, the direction of the magnetic field lines, the shape is like the magnetic field lines.

How to measure the quality of the heating plate of the induction cooker

Heat plate; length determines polarity. First, set the multimeter to R× 1K. When measuring with a multimeter, if the resistance of one pole and other poles is infinite, and the resistance of the pole and other poles is still infinite after changing the probe, determine the pole (G).

Is the heating plate really safe? How do we use it?

Is the heating plate really safe? How do we use it? Heating plate is very common in our daily life, and there are many applications of heating plate in industry. The use of high-power electrical appliances will generally pay attention to safety. If the circuit cannot drive high-power electrical appliances, it will cause short-circuit and other hazards, and the heating plate will still leak electricity, but this is a small part. After all, a finished heating plate needs to pass a safety test. Let's take a closer look at the heating plate manufacturers to see if the heating plate is safe and has no leakage.

What is the reason why the heating plate is not heated?

You may also have encountered the situation that the heating plate cannot be heated. Then let's analyze it together Reason 1: circuit failure Circuit faults are generally divided into two categories: power transmission, distribution, short circuits and short circuits due to loss of conversion control. Grounding, leakage, false closed circuit, OSS position, damage to electrical equipment or electrical components, etc. are all circuit faults.

The working principle of the heating plate

The heating plate is the heating part of the electric cooker, and it is also an important part of the cooking performance. The quality of its design depends on the heat conduction efficiency of the inner pot, the cooking effect, and the heat dissipation effect of the pot.

The heating plate manufacturer will talk about the matters needing attention in installing the electromagnetic heater.

The heating plate manufacturer will talk about the matters needing attention in installing the electromagnetic heater. In addition, another disadvantage of resistance wire heating is that the power density is low, which cannot be adapted to some occasions requiring higher temperature. Electromagnetic technology allows the metal cylinder to heat itself, which can be wrapped with certain insulation materials outside the cylinder according to specific conditions, thus greatly reducing heat loss and improving thermal efficiency. Therefore, the power saving effect is very significant, reaching 30% ~ 80%.
