Misuse of safety hazards caused by explosion-proof heaters

At present, the electric heater products in foreign intelligent temperature control instrument with low temperature detection and alarm function, and no electric heater circuit fault detection, some domestic enterprise production related products of large volume, complex configuration, alarm detection and poor reliability, convenient installation and maintenance, can not meet the needs of enterprises.

The market demand of electric heater products is large, which requires the transformation of the internal system of the electric heater and the high cost performance of the technology products in the electric heater, so as to facilitate the installation of the electric heater system.

The working principle of the internal device of the electric heater:

The open circuit fault measurement and control device of cast iron electric heater is connected to the contact point of the temperature control instrument between the electric heater and the electric heater, mainly using the current detection of the electric heater open and burn, and the detection of the voltage on the inside of the electric heater. If the instrument is normal contact on-off device has no effect on the normal electric heater in it, will only have no signal output in the electric heater; only when the electric circuit fault internal electric heater system heater device, electric heater in the signal output, and then the electric heater device and he (display, buzzer the host control, etc.) with the implementation of electric heater control requirements.

Electric heater is one of the equipments which are used more frequently in our work and life. Its safety is closely related to our safety. Therefore, we should repeatedly pay more attention to avoid all safety risks when we reuse it, so as to fully ensure the safe operation of the electric heater.

The electric heater is made of a resistance wire made of nickel and chromium alloy, and its temperature can be as high as 800 degrees centigrade. As the power of the heat-conducting oil and electric heater is relatively large, the risk of a fire may occur if a little attention is made when used.

From past cases, the reason why electric heaters cause fires is, on the one hand, that some users put electric heaters on combustibles or near flammable substances, causing fires in long time baking at high temperature.

On the other hand, the electric heater does not install the plug at all, but directly inserts the head of the wire into the socket, so it is easy to cause a short circuit and a fire. Another phenomenon is that the user doesn't pull the plug of the electric heater when he leaves. The time is too long, which causes the electric heater to overheat and ignite the nearby combustibles and cause the fire. In addition, if the wire of the electric heater has been repaired many times, it will cause a fire if it is still used.

In view of the above factors, in the use of electric heaters, they must not be placed near flammable explosives, and a certain safety distance must be maintained. And the electric heater must be placed on the unflammable material base without heat conduction; the safety of the wire must meet the capacity requirements of the electric heater.

Secondly, electric heater wire must be installed with plug. Electric heater wire should not be directly inserted into the socket. If there is aging and breakage, it must be replaced in time. If there is no fuse installed in the circuit, the electric heater can not be used.

The electric heater use must be manned, leave should be unplugged, in case of power outage should also be timely of the electric heater and pull the plug, do not forget. The resistance wire that has been repaired many times is not used as far as possible, so as not to cause greater loss.
