JLC-6S电流互感器二次过电压保护器
JLC-6S secondary overvoltage protectionDetails:

Electric Co., Ltd. Yueqing Dengrui factory direct【JLC-6S】,And provide a variety of【JLC-6S】Images, parameters, description and other detailed product information,Dengrui【JLC-6S】High quality, excellent price, special requirements can be customized consultation.


 Overview
    Current transformer (referred to as CT) in the operation of the secondary winding open circuit, or a winding stream through the abnormal over-current (thundering current, resonant current, the capacitor charging current, inductance, starting current, etc.) will be generated in the secondary side several thousand volts or even thousands of volts overvoltage. This will not only cause harm to the secondary system insulation, but also transformer excesses while burning, and even endanger the lives and safety of operating personnel, according to the actual needs of the power system, the company on the basis of the first generation of Transformers, we developed a action contact output, automatic light-emitting display, automatic locking differential protection, the protector of manual and automatic reset function, as well as the diverse combination of a variety of different functions in the action, the product is used in automatic control technology and high reliability components, service life long, can be reliably more than 100,000 times, the action is fast, strong overload capacity, static leakage current is small, to meet the needs of a variety of CT protection.
 
 use
    Modular current transformer secondary overvoltage protection is mainly used for a variety of CT secondary side of the abnormal over-voltage protection, protector, fixed in the CT secondary windings at both ends, a very small leakage current during normal operation, showed a high impedance state when the CT secondary circuit is open or a winding abnormal over-current, the secondary winding voltage is much higher than the normal operating voltage, the rapid movement of the protector while the short-circuit panel is displayed on the site of failure, and passive contact signal output, troubleshooting, according to the manual reset button circuit to restore the original state and then re-enter the normal operation of the work.
 
 wiring principle
Under normal circumstances, the current transformers are connected in A, B, and C, three-phase on a small number of connections on the two-phase, individually connected to one phase, the vast majority of the star connection, a small number for the delta connection, the protector secondary winding star connection. Secondary winding A, B, and C corresponding connected to the protector A, B, and C terminals A and B, and C, three-phase secondary neutral point (virtual N) connected to the protector of the N-terminal, if only in A, B, winding C phase can not wiring does not affect the normal work of the protector
