8200-205 超速保護(hù)器是一種電子設(shè)備，用于監(jiān)測(cè)和保護(hù)原動(dòng)機(jī)（如蒸汽輪機(jī)、燃?xì)廨啓C(jī)或原動(dòng)機(jī)）的運(yùn)行速度，以防止超速引起的潛在損害和故障。
該超速保護(hù)器通過(guò)三個(gè)獨(dú)立的轉(zhuǎn)速傳感器來(lái)監(jiān)控原動(dòng)機(jī)的轉(zhuǎn)速。當(dāng)檢測(cè)到超速情況時(shí)，保護(hù)器會(huì)激活跳閘繼電器，從而切斷原動(dòng)機(jī)的電源，使其停止運(yùn)行，從而防止設(shè)備受到進(jìn)一步的損害。
8200-205 超速保護(hù)器采用數(shù)字式速度感應(yīng)技術(shù)，具有高精度和重復(fù)性的特點(diǎn)。與傳統(tǒng)的機(jī)械式超速保護(hù)裝置相比，該保護(hù)器不需要為超速停機(jī)速度值給予足夠的余量，因此更加精確和可靠。此外，由于不涉及機(jī)械旋轉(zhuǎn)部分的磨損等問(wèn)題，8200-205 超速保護(hù)器可以長(zhǎng)時(shí)間保持停機(jī)速度設(shè)定值不變。
總之，8200-205 超速保護(hù)器是一種高效、可靠的保護(hù)設(shè)備，用于監(jiān)測(cè)和保護(hù)原動(dòng)機(jī)的運(yùn)行速度，防止超速引起的潛在損害和故障。它采用數(shù)字式速度感應(yīng)技術(shù)，具有高精度和重復(fù)性的特點(diǎn)，適用于各種需要保護(hù)原動(dòng)機(jī)的工業(yè)應(yīng)用。

8200-205

The 8200-205 overspeed protector is an electronic device used to monitor and protect the operating speed of a prime mover (such as a steam turbine, gas turbine, or prime mover) to prevent potential damage and failure caused by overspeed.
The overspeed protector monitors the speed of the prime mover through three independent speed sensors. When overspeed is detected, the protector activates the trip relay, which cuts off the power to the prime mover and stops it from operating, thereby preventing further damage to the equipment.
The 8200-205 overspeed protector uses digital speed sensing technology, which has the characteristics of high precision and repeatability. Compared with the traditional mechanical overspeed protection device, the protector does not need to give sufficient margin for the overspeed stop speed value, so it is more accurate and reliable. In addition, because it does not involve wear and tear on the mechanical rotation part, the 8200-205 overspeed protector can keep the stop speed set value unchanged for a long time.
In short, the 8200-205 overspeed protector is an efficient and reliable protection device for monitoring and protecting the operating speed of the prime mover to prevent potential damage and failure caused by overspeed. It uses digital speed sensing technology with high precision and repeatability, suitable for a variety of industrial applications requiring prime mover protection.
