two-phase relay
解釋
雙相繼電器-
Abstract : there are only two set values ( 30, 45 ) for interior angle of the stimulated directional power relay as the protection in phase to phase short circuit fault. an accurate setting formula for interior angle of the microprocessor - based directional power relay as the protection in phase to phase short - circuit fault is proposed and analyzed, users can set as a calculation value or at least an optimum in the formula. therefore the operation sensitivity and reliability of the directional relay would be improved greatly. the opinion is new and practical
文摘:保護相間短路的模擬式功率方向繼電器內角的整定值只有兩個（ 30 、 45 ） ，用戶只能在這兩個值中選其一；分析並提出了保護相間短路的微機型功率方向繼電器內角的準確整定計算公式，用戶可以整定為該公式的計算值或至少為最合理的值，從而能顯著提高方向繼電器的動作靈敏度及可靠性，具有新見解及應用價值。 -
At the same time, we have discovered some bug in cooperate between the two type protection, analyzed different result in different condition as config with different logic protection, show that the incorrect relay act result from these bug only appear when line is in incompletely phase operation and occur fault, furthermore the mass computer protection have comprehensive incompletely phase logic, so this condition can not seriously threaten the power system
同時，也發現了兩種保護裝置在配合上存在一些缺陷，分析了這種邏輯上的不配合在不同情況下所造成的不同後果，並且指出由於這些缺陷所造成的保護裝置不正確動作的情況僅在線路非全相運行時又故障的情況下才可能出現，而且現有的成套微機保護的都具有較為完善的非全相邏輯，在保護裝置正常投運的情況下，還不致對系統安全構成重大隱患。 -
Some do not set up the reference over - current protection units, some only install a simple two - phase type two current relay over - current protection units, which of them can not function for the over - current protection, and damage equipment and affect the enterprise production
有的不設置標準過流保護裝置，有的只設置簡單的二相式二隻電流繼電器過流保護裝置，這樣往往起不到過流保護作用，從而損壞設備，影響企業的生產。 -
Sync check relay a sync check relay is an electrical device that monitors the phase relationship between two voltage sources and provides a signal when the voltage sources are within specific preset parameters
同步檢查繼電器同步檢查繼電器是監測兩個電壓源之間的相位關系的電氣設備，如果電壓源間的關系在預定的參數范圍內，它就會發出相應信號。
