BT-1B型同步檢查繼電器
BT-1B型同步檢查繼電器產(chǎn)品介紹
BT-1B型同步檢查繼電器是一款專為兩端供電系統(tǒng)自動重合閘線路設(shè)計的電力保護設(shè)備，主要用于檢查線路的電壓有無和同期情況。該繼電器采用先進的靜態(tài)繼電保護技術(shù)，具有高精度、高可靠性和快速響應(yīng)的特點。其核心部件包括電壓互感器、整流濾波回路、觸發(fā)器及干簧繼電器等，能夠準(zhǔn)確檢測兩個交流電壓或電流的相位差和幅值差異。當(dāng)檢測到不同相或電壓異常時，繼電器會迅速動作，確保電力系統(tǒng)的安全運行。該產(chǎn)品適用于多種電壓規(guī)格（220V/110V/48V），頻率為50Hz，動作角度整定范圍為20°~40°，可滿足不同電力系統(tǒng)的需求。126
BT-1B Synchronization Check Relay Product Introduction
The BT-1B Synchronization Check Relay is designed for automatic reclosing circuits in dual-power supply systems, primarily used to verify voltage presence and synchronization conditions. This relay features static protection technology with high precision, reliability, and rapid response capabilities. Its core components include voltage transformers, rectifier-filter circuits, triggers, and reed relays, which accurately detect phase differences and amplitude variations between two AC voltages or currents. When detecting phase mismatch or voltage anomalies, the relay operates promptly to ensure power system safety. The product supports multiple voltage specifications (220V/110V/48V) at 50Hz frequency, with an adjustable operating angle range of 20°~40°, making it suitable for diverse power system requirements. The compact design and efficient performance make it an ideal solution for power protection applications.41015
技術(shù)特點與工作原理
該繼電器采用JK-2型標(biāo)準(zhǔn)殼體結(jié)構(gòu)，通過兩個電壓互感器反極性連接實現(xiàn)相位比較。當(dāng)輸入電壓同相時，二次側(cè)輸出電壓趨于零；出現(xiàn)相位差時則產(chǎn)生與差值成比例的感應(yīng)電勢，經(jīng)整流濾波后觸發(fā)動作機構(gòu)。獨特的設(shè)計使其具備自動檢測功能，在任一輸入電壓缺失時同樣能可靠動作。電位器R8提供了20°-40°的動作角度靈活整定，返回系數(shù)不低于0.85，功率消耗低于6W（220V時），在80%-110%額定電壓范圍內(nèi)均可穩(wěn)定工作。3712
Technical Features and Operating Principle
Utilizing a JK-2 standard housing, the relay employs inversely connected voltage transformers for phase comparison. When voltages are synchronized, secondary output approaches zero; phase differences generate proportional induced potential that triggers operation after rectification and filtering. Its innovative design ensures reliable operation even during single-phase voltage loss. The adjustable operating angle (20°-40°) is set via potentiometer R8, with return coefficient ≥0.85 and power consumption <6W (at 220V). Stable performance is maintained within 80%-110% of rated voltage. The relay demonstrates excellent anti-interference capability and meets general industrial environmental requirements.91417
應(yīng)用場景與安裝說明
該產(chǎn)品適用于不允許存在爆炸性介質(zhì)、強振動及腐蝕性氣體的電力環(huán)境，需配備防雨雪設(shè)施。典型應(yīng)用于變電站自動重合閘系統(tǒng)、雙電源切換裝置等場景，能有效防止非同期合閘造成的設(shè)備損壞。安裝時需注意：多個繼電器并裝時應(yīng)保持左右間距＞25mm，上下間距＞30mm；大電感負(fù)載建議連接RC滅弧網(wǎng)絡(luò)（300Ω/0.1μF）以延長觸點壽命。采用背后端子接線方式，配套提供JK系列插座組件（需單獨訂貨）。81316
Applications and Installation Guide
Designed for power environments excluding explosive atmospheres, strong vibrations, and corrosive gases (with rain/snow protection required), the relay is typically deployed in substation auto-reclosing systems and dual-power transfer devices to prevent equipment damage from asynchronous closing. Installation notes: maintain >25mm lateral and >30mm vertical spacing for multiple relays; RC networks (300Ω/0.1μF) are recommended for inductive loads to extend contact life. Rear terminal wiring is adopted, with compatible JK-series sockets available as separate accessories. The product s robust construction ensures long-term operation in temperatures from -25°C to +50°C.111820
