Pembekal suis pemotongan terma bimetal permukaan bimetal

China custom bimetallic thermal disc cutoff switch has surface mount and PCB plug-in installation. Overheat circuit cutoffs switch (termostat dwilogam) Adakah peranti yang direka untuk memastikan komponen selamat dalam situasi apabila suhu yang berlebihan berlaku. List of Select Surface Mount Thermal Switches and thermal protectors product Specs, datasheets, manufacturers & suppliers.

Surface Mount Bimetal disc Thermal Switch are indispensable components in the safe and efficient operation of motors/ Electrical appliances. Dengan mengelakkan terlalu panas, they protect Electrical appliancesfrom damage, memanjangkan hayat operasi mereka, mengurangkan risiko bahaya kebakaran, memastikan operasi selamat, dan meminimumkan masa henti dan kos penyelenggaraan. Tambahan pula, Bimetal disc thermal switch help in complying with industry safety standards, memberikan ketenangan fikiran kepada pengendali dan pihak berkepentingan. Apabila teknologi semakin maju, thermal switch continue to evolve, menawarkan perlindungan yang lebih tepat dan boleh dipercayai untuk motor dalam pelbagai aplikasi.

Dengan perkembangan teknologi, julat aplikasi motor adalah lebih dan lebih luas, terutamanya penggunaan motor dalam kehidupan harian dan pengeluaran juga semakin penting. Tetapi kemalangan terbakar motor juga berlaku, dalam kehidupan sebenar, terbakar motor terutamanya disebabkan oleh gegelung tersumbat berikut terlalu panas, beban terlalu besar beban motor, kekurangan fasa dan sebab lain. Installing a heat protector is one of the effective ways to protect the motor. suis terma, juga dipanggil suis suhu, suis kawalan suhu, dll. Ia adalah sejenis suis suhu dengan kepingan dwilogam sebagai elemen pengesan suhu, apabila perkakas elektrik berfungsi seperti biasa, kepingan dwilogam berada dalam keadaan bebas, kenalan berada dalam keadaan terputus, apabila suhu meningkat kepada nilai suhu tindakan, unsur dwilogam dipanaskan untuk menghasilkan tekanan dalaman dan tindakan pantas, buka kenalan, potong/sambungkan litar, so as to play a bimetal thermal switch role. Wait until the ambient temperature drops to thereset temperature of the protector, sesentuh akan menutup semula litar yang disambungkan, dan motor akan berfungsi semula.

Choosing The Right thermal switch
How to choose the right circuit Off bimetal disc switch is very important, sebaliknya bukan sahaja tidak boleh memainkan peranan pelindung, tetapi akan menyebabkan motor tidak boleh berfungsi kerana tersalah pemilihan, atau pun terbakar.

1. Voltan & Keazaman semasa
• Bimetal disc thermal switch have different voltage ranges 400V 380V 230V 220V 110V, DC motors will also have 36V 24V 12V, dll., according to different working voltages to choose different rated voltage protectors, pada dasarnya, voltan aplikasi sebenar adalah kurang daripada atau sama dengan voltan terkadar pelindung, contohnya, 380V motor cannot choose rated voltage 220V protector, dan pelindung voltan terkadar 220V boleh digunakan dalam motor 110V;

• The current of the electrical appliances motors is divided into three kinds of starting current, arus kerja biasa dan arus terhalang, the rated current of the protector should be greater than the maximum value of the three currents, dan perlu meninggalkan margin. Contohnya, motor arus kerja biasa 1A, permulaan arus 1.5A, menyekat arus 2A, then the rated current of the selected protector is at least 2A, dan yang terbaik adalah memilih arus undian 3A atau 5A untuk mengekalkan margin. Some motor starting current is greater than the rated current of the protector, tetapi masa permulaan adalah lebih singkat, dan arus kerja biasa dan arus penyekat adalah kurang daripada arus undian pelindung, dalam kes ini, anda juga boleh memilih pelindung ini. Kerana arus permulaan lebih besar daripada arus undian, tapi disebabkan masa yang singkat, the thermal effect of the current has not had time to make the double piece heat leading to protection of the protector, supaya tidak menimbulkan salah laku.

2. Choose to thermal switch the temperature
• The choice of thermal switch temperature is related to three factors: insulation level of enameled wire, installation position and protector type.

The thermal switch temperature is lower than the maximum allowable temperature, contohnya, the maximum temperature ofF class is 155℃, and the actual selection can be 145℃ or 150℃.

•The installation position is divided into built-in inside the coil and bundled outside the coil, because when the motor is blocked and forwarded heat, the overheating phenomenon spreads from inside and outside. If the protector is buried in the interior, the thermal switch temperature is slightly lower than the highest temperature of the enamelled wire; If it is tied outside the coil, consider the temperature difference between the inside and outside, and choose a lower temperature protector. Contohnya, the insulation level is F class enameled wire, coil inside and outside the temperature difference of 20℃, then choose 155-20=135℃ or so of the protector;

Motor protector has protection functions such as overload, kegagalan fasa, imbalance, underload, grounding/leakage, dan gerai. It can form a motor control protection unit with electrical components such as contactors and motor starters. It has functions such as remote automatic control, on-site direct control, panel indication, signal alarm, and field bus communication.

3. Selection of the thermal switch life
Different motor lock-in test time different requirements for the life of the protector are not the same, such as normal household motor lock-in 18 hari, the number of cycles of normal action reset will not exceed 100000 kali, the rated voltage current life of more than 100000 times can be selected protector; Some pump motors only do 3 days of blocking, pada dasarnya, the life requirement is hundreds of times.

4. Selection of the thermal switch for sealing performance
Motor coil in the thermal switch process will dip paint to enhance the insulation performance of the process, dip paint is divided into drop paint, rendaman, vacuum into the paint and other processes, especially the vacuum into the paint pressure is large, insulating paint is easy to enter the inside of the protector, resulting in the failure of the protector. The ST01 series of An Electronics has a very high sealing, under the condition of -0.08MP, the paint dipping rate can reach 3%; In the case of -0.03MP, the paint rate can reach less than one in ten thousand.
