The electric resistance of the electric heater is made of nickel, chromium alloy, and the temperature is as high as 800 ° C or higher. Since the power of the electric heater is relatively large, if the user neglects the security, the fire is likely to happen. The reasons for the fire in electric heaters are: First, place the power-on electric heater in flammable or in the vicinity of flammable, personal heater causing fire under long-term high temperature baking. Second, the electric heater is not installed, directly insert the wire head into the socket, and it is easy to cause a short circuit. Third, the use of electric heater unloaded the plug of the electric heater when leaving, the time is too long, causing the electric heater overheating, and the adjacent combustible material is ignited to cause fire. Fourth, the resistance wire continues to use after multiple repairs, causing a line overload to cause a fire.

Therefore, in use, the flammable and explosive article cannot be placed near the electric heater, and a certain safe distance must be maintained. The electric heater must be placed on the non-thermally conductive non-combustible material base; the safety shuttle of the electric heater wire must satisfy the capacity of the electric heater, and the industrial electric heater must be a separate circuit in any case. The wire must be installed in the wire, and the electric heater thread should not be inserted into the socket; the aging damage of the electric heater wire should be replaced in time, the electric heater without the installation of the fuse is not used; the electric heater must be used, and some people must be taken. Unplug the plug, during use, if there is a power outage, you should also pull out the electric heater plug, don’t forget. For a multi-repaired resistor, it is best not to use, and the new resistor should be replaced. The flammable and explosive article is strictly forbidden to use electric heater to dry; the electric oven should have a device for controlling the temperature, and it is necessary to prevent the temperature excessively, and prevent the electric heater from baking the overspeaker.
