Surface Mount Bimetal disc Thermal Switch are indispensable components in the safe and efficient operation of motors/ Electrical appliances. 過熱を防ぐことで, they protect Electrical appliancesfrom damage, 動作寿命を延ばす, 火災の危険を減らす, 安全な操作を確保する, ダウンタイムとメンテナンスコストを最小限に抑えます. さらに, Bimetal disc thermal switch help in complying with industry safety standards, オペレーターと関係者に安心を提供する. テクノロジーが進歩するにつれて, thermal switch continue to evolve, 幅広い用途において、より正確で信頼性の高いモーター保護を提供します。.

テクノロジーの発展に伴い, モーターの応用範囲はますます広がっています, 特に日常生活や生産におけるモーターの使用もますます重要になっています。. でもモーター焼損事故も起きる, 実生活では, モーターの焼けは主に次のブロックされたコイルの過熱によって引き起こされます。, 負荷が大きすぎるモーター過負荷, 位相不足やその他の理由. Installing a heat protector is one of the effective ways to protect the motor. サーマルスイッチ, 温度スイッチとも呼ばれます, 温度調節スイッチ, 等. バイメタルシートを感温素子として使用した一種の温度スイッチです。, 電化製品が正常に動作しているとき, バイメタルシートはフリー状態です, 接点が切断された状態です, 温度が動作温度値まで上昇したとき, バイメタル要素が加熱されて内部応力が発生し、迅速な動作が発生します。, 連絡先を開く, 回路を切断する/接続する, so as to play a bimetal thermal switch role. Wait until the ambient temperature drops to thereset temperature of the protector, 接点は接続された回路を再び閉じます, そしてモーターは再び動きます.

Choosing The Right thermal switch
How to choose the right circuit Off bimetal disc switch is very important, そうしないと、保護的な役割を果たすことができないだけでなく、, しかし、間違った選択によりモーターが動作しなくなる可能性があります。, あるいは火傷さえする.

1. 電圧 & 現在の判定
• Bimetal disc thermal switch have different voltage ranges 400V 380V 230V 220V 110V, DC motors will also have 36V 24V 12V, 等, according to different working voltages to choose different rated voltage protectors, 原則として, 実際の印加電圧はプロテクタの定格電圧以下です。, 例えば, 380V motor cannot choose rated voltage 220V protector, 定格電圧220Vのプロテクターは110Vモーターでも使用可能;

• The current of the electrical appliances motors is divided into three kinds of starting current, 通常の動作電流と遮断された電流, the rated current of the protector should be greater than the maximum value of the three currents, そしてマージンを残す必要がある. 例えば, モーターの通常の動作電流 1A, 始動電流 1.5A, 阻止電流2A, then the rated current of the selected protector is at least 2A, マージンを確保するには、定格電流 3A または 5A を選択するのが最善です。. Some motor starting current is greater than the rated current of the protector, ただし開始時間は短い, 通常の動作電流と遮断電流はプロテクタの定格電流より小さい, この場合, このプロテクターを選択することもできます. 始動電流が定格電流より大きいため, しかし時間が短いため, the thermal effect of the current has not had time to make the double piece heat leading to protection of the protector, 誤作動を起こさないように.

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, 例えば, 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. 例えば, 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, phase failure, imbalance, underload, grounding/leakage, and stall. 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 日, the number of cycles of normal action reset will not exceed 100000 回, the rated voltage current life of more than 100000 times can be selected protector; Some pump motors only do 3 days of blocking, 原則として, 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, immersion, 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.
