Three-phase total complement complex switch xyFK- △ 380V-45A

Three-phase total complement complex switch models: xyFK- △ 380V-45A instrument Information: xyFK series of intelligent low voltage composite switch is an intelligent environment-friendly low-voltage capacitor switching switch, the integration of SCR and AC contactor advantages. Works by SCR and relay and connected, the composite switch has the advantage of instant switching thyristor zero switching, and have turned an advantage during normal contactor without power. Up for the lack of SCR and AC contactor in low voltage reactive compensation applications. The main advantage of this product is: After receiving an external control signal, through intelligent judge, automatically find the best switching point, to ensure zero switching, inrush current is small, the contact is not sintered, low energy consumption; both abnormal voltage protection, lack of protection, protection from component failures, operational instructions and other functions. Product Category Products by connection capacitance compensation divided into two categories delta and star connection: 2 three-phase total complement of type: the triangular connection (indicated by △) 2 three-phase sub-fill type: the star connection ( represented by 3Y) the main technical features of zero switching composite switch the basic working principle is to thyristor switches and relays, and then achieve zero-voltage and zero current turn-on cutting, the composite switch in the ON and OFF moment has zero switching thyristor advantages, but there are contacts after turning on the advantages of no power switch. This is accomplished by: The input voltage is at zero-crossing triac trigger first turned on, to stabilize before the relay is turned on and off when the cut is the first relay, SCR zero crossing off delay for current zero removed. SCM control protection switching, intelligent monitoring SCR, relays, and input power and load operating conditions so as to have complete protection. Voltage fault phase protection: When the system voltage phase power supply, the switch refused to close; and in the event of phase after switching is automatically disconnected. Power supply voltage phase protection: when the power supply phase power supply, the switch refused to close; if there is phase after switching is automatically disconnected. Self-diagnostic fault protection: The system automatically monitors thyristor, relay running, if fails, then refused to close or automatically disconnected. No-load protection: no load switch refused closed. Power protection: When turned on, the case of a sudden power outage, automatically disconnected. SCR power consumption and instantaneous relay only in switching power, usually no power, in order to achieve energy saving. Job security and the composite switch control signal isolation. Due to the use of advanced intelligent control technology and patents devices, compared with similar products in the surge and reliability with a high safety performance advantages. ?
