A, oil immersed RC absorber overview

ZR oil immersed RC absorber can suppress the voltage range of 48Hz-1000KHz, is different from the current market the overvoltage protector can only inhibit the over voltage in the range of 48Hz-62Hz, dedicated to 66KV and the voltage of the system, effectively limit the over-voltage on the circuit breaker and reactor inductive load damage. Suitable for metallurgical smelting and reactor application.

Two, oil immersed RC absorber characteristics

1, professional protection
2, powerful
3, reduce the steepness of the effective protection of the inter turn
4, automatic control access response quickly
5, no gap design, stable operation characteristics
6, do not provide additional capacitive current to the grid
7, for the design, protection in place
8, with auxiliary protection function
9, high efficiency and energy saving, low working temperature
10, short time work, long life
11, absorption of energy, a wide range of protection
12, safety and environmental protection, can adapt to the complex environment of power grid operation

Three, performance index

1, the measured resistance and capacitance and its rated value of the difference should not exceed the rated value of + 5%, phase capacitance ratio of the maximum and minimum values is less than 1.08, phase resistance maximum value and minimum value difference is less than 8;
2, loss tangent value is less than or equal to 0.0012 (excluding internal resistance);
3, ambient air temperature range -40 C ~+40 C, altitude is not more than 1000m;
4, the relative humidity is less than 80%, non flammable and explosive gas and damage to the absorber and chemical sites;
