Purpose and scope FFM type of protection may constitute a capacitor due to the vacuum circuit breaker (or other non-weight breakdown of the switch) generated by opening and closing of over-voltage RC filter absorbing device for transmission and distribution systems and exchanges 35KV high-voltage resistor in series with the absorption overvoltage protection system in a high-voltage electrical appliances from voltage damage, the product can also be used as high-voltage capacitors used in other occasions. Conditions of Use main technical indicators MAIN TECHNIQUEINDESSIGN ◆ capacitance deviation -5 ~ +10% ◆ loss tangent tan □ 0.05% ◆ electrical appliances strength of the medium 2.15u, which lasted 1min ◆ The remaining technical requirements are in accordance with "GB.T4704-32 high-voltage shunt Capacitors "◇ Capacitance Deviation: -5 ~ +10% ◇ Tangent of Loss Angle tan <0.05% ◇ Electrical Strength of Dielectric Medium2.15u, Last a period of time: 1 min ◇ The other technology requirement is according to" GB.T4704 -62 High voltage shunt Capacitor conditions SERVIECONDITION ◆ capacitor installation and operation of the poster does not exceed the height of 1000m, ambient air temperature is -40 ~ +40 ℃, relative humidity less than 98% ◆ installation site should be no corrosive gas, steam and electrical conductivity or explosive dust, when there is no severe mechanical vibration ◆ capacitor put into operation, the residual voltage on its terminals does not exceed 10% of rated voltage ◆ Over load & over voltage stable continuous operation voltage 1.00u, and be able to 1.2u, frequency Over the long run · operating voltage over-voltage capacitors withstand heavy breakdown is not generated by the transition 5u switch over voltage (peak) · Steady Steady overcurrent capacitor can run at 1.5In over current, over-current is due to the The results refer to the wave, and high maximum tolerance to 1.2 overcurrent joint action
