Described overtemperature protection system comprises connected successively temperature sensor, controller and alarm, and controller is connected with external power source.Temperature sensor detects that the temperature in metal tube exceedes limit value, signal is transferred to alarm and controller, and the alarm prompting staff measure of handling it that gives the alarm, cuts off extraneous power supply with Time Controller, suspends the work of heating wire; When temperature retrieval in metal tube is during to normal level, temperature sensor is transferred to controller by signal again, and controller is connected extraneous power supply, and heating wire is worked on, and guarantees the constant of temperature in mobile field camp.
Described insulator is nano aluminum nitride compound silica gel.Traditional megohmite insulant mostly is magnesia powder, but magnesia powder kind is on the market numerous and diverse, quality level is uneven, when heating wire work, be easy to cause heat in metal tube to gather, cause the damage of metal tube, and the nano silicon nitride aluminium powder that the present invention adopts, thermal coefficient of expansion is little, good with semiconductor silicon matching, there is high heat conduction, good, the resistant to elevated temperatures performance of electrical insulating property, can guarantee that metal pipe has longer service life.
Also comprise aluminium bar, the bending two ends of described aluminium bar, heating wire winding is arranged on aluminium bar.The aluminium bar arranging can play the function of interim reparation in the time that heating wire is impaired, guarantees to work in heating wire is during certain.
Described heating wire is nichrome heating wire.Nichrome heating wire intensity in hot environment is high, and long term high temperature operation is not yielding, be difficult for change structure, and the normal temperature plasticity of nichrome heating wire is good, and the reparation after sex change is comparatively simple.In addition, nichrome heating wire radiance is high, and not good, the long service life of carrying magnetic, corrosion resistance contributes to guarantee the job stability of heater.
The present invention compared with prior art, has following advantage and beneficial effect:
1, a kind of heater for mobile field camp of the present invention, comprise housing, heating wire, binding post and multiple being staggered are arranged on the metal tube of enclosure interior, on described housing, have multiple through holes, heating wire is arranged in metal tube, the two ends of metal tube are provided with plug, binding post is connected with heating wire through plug, binding post is connected with external power source, also comprise insulator and overtemperature protection system, described insulator is arranged between heating wire and metal tube, described overtemperature protection system is arranged on the through hole of enclosure interior, and overtemperature protection system is connected with binding post, be arranged on the overtemperature protection system of through hole, in the time that enclosure interior temperature is elevated to maximum, overtemperature protection system just will cut off being connected between metal tube and external power source, until temperature recovery is to normal level, external power source continues power supply, and heating wire continues heating, has avoided high temperature to cause the phenomenon that heating wire blows to occur, also the job stability that has improved heater, has guaranteed the service life that it is permanent simultaneously,
2, a kind of heater for mobile field camp of the present invention, traditional megohmite insulant mostly is magnesia powder, but magnesia powder kind is on the market numerous and diverse, and quality level is uneven, when heating wire work, be easy to cause heat in metal tube to gather, cause the damage of metal tube, and the nano silicon nitride aluminium powder that the present invention adopts, thermal coefficient of expansion is little, good with semiconductor silicon matching, there is high heat conduction, good, the resistant to elevated temperatures performance of electrical insulating property, can guarantee that metal pipe has longer service life;
