First, the scope

YU9-C Series modular surge protector Chase stream suitable for doors AC 50/60Hz, rated voltage 380V and below the TT, IT, TN-S, TN-C, TN-CS and other power supply system on the grid due to lightning or Surge overvoltage protection. Its design basis in line with C61643-1, GB18802-2002 it can discharge lightning current 100KA, housing design mounted on 35mm electric rail, which from the device can automatically remove it from the power line, while the status indicator window from green to red .
Surge Protector has a common mode (MC) and (MD) differential mode protection. Surge protection accord GB18802.1, IEC61643-1 and other standards.

Second, model and specification



Third, the surge protector role

surge protector uses a nonlinear characteristics of excellent varistor, under normal circumstances, a surge protector outside in a high resistance state, the leakage current is almost zero, guaranteed power supply system normal power supply. When the power supply system in the above situation overvoltage, surge protectors immediately turned quickly in the nanosecond time, the amplitude of the voltage is too limiting, within the safe operating range of the device. While the energy of the overvoltage released. Subsequently, the surge protector and quickly becomes a high impedance state, and therefore does not affect the normal power supply system.

Fourth, the structure and working principle

surge protector in the three-phase four-wire system are connected with protection between the three phases and a neutral ground butt. Under normal circumstances the protector in a high resistance state, when the grid due to lightning or other overvoltage surge occurs, the protection will now quickly turned in the nanosecond time, the surge voltage into the earth, thereby protecting the power line electrical equipment. When the surge voltage through the protective device, and the disappearance of the protector again to a high resistance state, so as not to affect the normal operation of the grid.

Nine, why should surge protector

Devastating lightning, switching power supply alone external lightning (lightning, etc.) is not enough, lightning will be, directly or indirectly invade each electrical path and the metal channels (such as power cables, signal lines (via electromagnetic induction), day feeders and metal pipes, etc.). The resulting over-voltage lightning and surge voltage will be electronic, electrical equipment, information network system to produce great harm, ranging from the destruction of the line, while damage to the equipment, the system is paralyzed, resulting in incalculable loss.
Lightning current rapidly changing, in electrical induction loops and double-strand wire generates a high voltage caused by the insulation system is destroyed. A variety of operating power system operation can produce over-voltage in the power line; some electrical equipment switching operations, short trips, etc. can produce higher than normal operating voltage of over-voltage (surge) in power lines resulting in harm to electrical equipment .
