Definitions
- the invention relates to an electronic cut-out preventing electric and/or electrically controlled consumers from undesirable temperature changes, such as j welders for plastics, electric boilers, cookers. re ri erators, kettles, electrically controlled furnaces, 1 ectric iron . etc .
- undesirable temperature changes such as j welders for plastics, electric boilers, cookers. re ri erators, kettles, electrically controlled furnaces, 1 ectric iron . etc .
- a further* problem is represented by tolerances of swi tr;hir ⁇ g-off temperatures of fuses, caused e. ⁇ . by ageing of metals applied in safety elements.
- the unreliability is also caused by liquid comprised in some systems of a thermal fuse or of a break-down thermostat. M S the fuse can, in extreme cases, swi ch off prematurely or it does not switch off at all. Said drawbacks aff ct the reliability of the fuses, as well as the safety of the consumer and of operation.
- the subject of the invention is represented by an electronic cut-rmt preventing electric an /or electrically contr ll d consumers from undesirable temperature chancres which, according to the inventi n, consists of a i- ⁇ h interrupting-capa ity switch, connected between a source of electric power and a consumer, and connected to an evaluating circuit which is connected to a temperature p ⁇ rk ⁇ ng-up circuit, particularly thermosensor. connected to the consumer in a thermally conductive way. Between r i the consumer and the source of electric power there may be advantageously connected thermore ⁇ ulatoi .
- the evaluation circuit, the high interrupting- apa ity switch and the thermoregulator may have, advantageously, some electric elements common.
- the evaluation circuit may be advanta ⁇ eous ly
- the hi rh interrupting-capacity switch is advanta ⁇ eou ly represented by an active switchin ⁇ element, such as a triac. ll thy ⁇ stor , relay, connector or selenoid.
- the evaluation circuit disconnects voltage for the high interrupt,lrig-capacity switch, which disconnects the supply of electric power (electric current . eras, oil. and the
- the consumer provided with the electronic cut-out acnrdin ⁇ to the invention is reliable, ithout defect: , and it, can work within a large scope of temperatures - Best, Mode for tarrying out the invention
- the electronic cut-out consists of the high
- thermoregulator TR The output of the thermore ⁇ ul ator TR is connected to
- the hi h interrupting- -capacity switch HICS may be connected directly to the source S of electric power S.
- the high interrupting- -capacity switch HICS is represented e.g. by a triac, thyristor, relay, connector or selenoid.
- To the output of the high interrupting-capaci ty switch HICS there is connected the consumer S.
- the excitation of the high interrupting-capacity switch HICS is performed from the evaluation circuit EC.
- the input of the evaluation circuit EC is connected to the thermal sensor TS which is also connected to the input of the thermoregulator TR.
- thermoregulator TR and the evaluation circuit EC may have some components common, such as microprocessor, integrated ci rcui1, , res i stor , etc .
- Industri l Appl icabi lity The electronic cut-out according to the invention may be utilized in electric consumers or electrically controlled ones, such as in portable welders for welding piping made of plastics, electric irons, cookers, r f ri gerators etc .
