Tipes oppervlakmontage-termoskakelaar & Bimetal Motor Thermal Protector
Daar is verskeie tipes termoskakelaar vir oppervlakmontering & bimetaal beskermers, elkeen geskik vir verskillende toepassings en motortipes:

Bimetaal termiese beskermers (Surface Mount): Hierdie gebruik 'n bimetaalstrook wat buig wanneer dit verhit word, aktiveer die skakelaar om die kragtoevoer te ontkoppel. Hulle word algemeen in klein motors en toestelle gebruik.

NTC / PTC Thermistor-Based Protectors: These use temperature-sensitive resistors (NTC / PTC termistors) to monitor the motor’s temperature. They provide precise temperature sensing and are often used in more sophisticated applications.

Electronic Thermal Protectors: These use electronic circuits to monitor and control the motor’s temperature. They offer advanced features such as adjustable temperature sensor thresholds and remote monitoring capabilities.

Surface Mount thermal protector are indispensable components in the safe and efficient operation of motors. Deur oorverhitting te voorkom, they protect motors from damage, hul operasionele lewe verleng, verminder die risiko van brandgevare, veilige werking verseker, en verminder stilstand en onderhoudskoste. Verder, thermal protector switch help in complying with industry safety standards, verskaf gemoedsrus aan operateurs en belanghebbendes. Soos tegnologie vorder, thermal protector switch continue to evolve, offering more precise and reliable protection for motors in a wide range of applications.

Met die ontwikkeling van tegnologie, the application range of motor is more and more extensive, especially the use of motor in daily life and production is also more and more important. But the motor burn accident also happens, in real life, the motor burn is mainly caused by the following blocked coil overheating, the load is too large motor overload, lack of phase and other reasons. Installing a bimetal heat protector switch is one of the effective ways to protect the motor. Termiese beskermer, also called temperature switch, Temperatuurbeheerskakelaar, Bimetaal termostate, ens. It is a kind of temperature switch with bimetal sheet as a temperature sensing element, when the electrical appliance is working normally, the bimetal sheet is in a free state, the contact is in a disconnected state, wanneer die temperatuur styg tot die aksietemperatuurwaarde, die bimetaalelement word verhit om interne spanning en vinnige werking te produseer, maak die kontak oop, die stroombaan afsny/koppel, so as to play a thermal protection role. Wait until the ambient temperature drops to thereset temperature of the bimetal protector, die kontak sal die gekoppelde stroombaan weer sluit, en die motor sal weer werk.

Choosing The Right Surface Mount Thermoswitch & Protector
How to choose the right thermal protector is very important, anders kan nie net 'n beskermende rol speel nie, maar sal veroorsaak dat die motor nie kan werk nie as gevolg van die verkeerde keuse, of selfs brand.
1. Spanning & Huidige vasberadenheid
• Motors have different voltage ranges 380V, 230V, 220V ,110V, DC motors will also have 36V/ 24V /12V, ens., according to different working voltages to choose different rated voltage thermal protectors, in beginsel, die werklike toepassingsspanning is minder as of gelyk aan die nominale spanning van die beskermer, byvoorbeeld, 380V motor cannot choose rated voltage 220V thermal protector, en nominale spanning 220V beskermer kan gebruik word in 110V motor;

• The current of the motor is divided into three kinds of starting current, normale werkstroom en geblokkeerde stroom, the rated current of the thermoswitch & protector should be greater than the maximum value of the three currents, en moet 'n marge laat. Byvoorbeeld, 'n motor normale werkstroom 1A, beginstroom 1.5A, blokkeerstroom 2A, then the rated current of the selected thermal protector is at least 2A, en dit is die beste om die nominale stroom van 3A of 5A te kies om die marge te behou. Some motor starting current is greater than the rated current of the thermal protector, maar die begintyd is korter, en die normale werkstroom en blokkeerstroom is minder as die nominale stroom van die beskermer, in hierdie geval, jy kan ook hierdie beskermer kies. Omdat die beginstroom groter is as die aangeslane stroom, maar as gevolg van die kort tyd, the thermal effect of the current has not had time to make the Bimetal heat leading to protection of the thermal protector, om nie mishandeling te veroorsaak nie.

Thermoswitch and Thermal Protectors Set-point Temperature
Thermoswitch and Thermal Protectors Specification Guide Thermoswitch and thermal protectors have a set point temperature that is either fixed or field adjustable. Die stelpunt is die aangewese temperatuur waarteen die toestel 'n toestandsverandering ondergaan wat verband hou met die beweging van die elektriese kontakte. Vastepunttoestelle word teen 'n gegewe temperatuur gegradeer terwyl veldverstelbare toestelle 'n temperatuurreeks het waaroor die stelpunt aangepas kan word.

Thermoswitch and Thermal Protectors Hysteresis:
Histerese, ook na verwys as die temperatuurverskil, is 'n eindige temperatuurreeks waaroor omskakeling plaasvind. Dit is ontwerp om te verhoed dat stroombane voortdurend tussen state verander. N histerese van 0.5 C sal tipies aktiveer 0.5 grade verby die instelpunttemperatuur en nie weer van toestand verander voordat die temperatuur tot 0.5C onder die instelpunttemperatuur daal nie.

Thermoswitch and Thermal Protectors Maximum current:
Die maksimum stroomaanslag is die maksimum elektriese las in ampère wat die kontakte van die elektriese skakelaar ontwerp is om te dra.

Thermoswitch and Thermal Protectors Maximum voltage:
The Thermoswitch maximum voltage rating is the greatest potential difference that the device is designed to hold across open switch contacts without arcing or development of a current. Die maksimum spanning word vir wisselstroom gespesifiseer (AC) en gelykstroom (DC), met AC wat 'n groter selfdovende neiging van 'n boog oor 'n luggaping toon en dus 'n groter potensiaalverskil kan hou.
