Product Description

Product Details
 Self-healing low-voltage shunt capacitors are suitable for AC 50Hz(60 Hz),rated voltage 1000V and below AC power systems to improve power factor,reduce reactive power loss,and improve voltage quality.

Main technical  parameter

1.Loss tangent value	less than 0.0012 under power frequency rated voltage;
2.Capacitance deviation	The difference between the measured value and the rated value of the capacitor shall not exceed 0~+3%; The ratio of the maximum capacitance to the minimum capacitance measured between any two line terminals in a three-phase capacitor is not greater than 1.08;
3.Withstand voltage	inter-electrode:powerfrequency2.15Un,2S; pole-to-shell rated voltage 600V and below,applied voltage3.6kV,5s;rated voltage600V and above Applied voltage7.2kV,5s;
4.The highest allowable overvoltage	1.1Un,no more than 8hin every24h;
5.Maximum allowable overcurrent	1.3In;
6.Self-discharge characteristics	The capacitor has a discharge device,which can make the residual voltage of the capacitor drop from 2Un to 50V or below within 3 minutes of disconnecting the power supply
7.Executive standard	GB/T12747.1

Dimensional drawing
 

Matters needing attention
 1.Overvoltage and overheating will shorten the life of the capacitor.Therefore,the operating conditions(ie:ambient temperature,voltage and current,etc.) should be strictly controlled.
 2.When installing parallel capacitors in the system,full attention should be paid to the following:
 A). In an environment with serious harmonic content,it is not suitable to directly install parallel capacitors,please use anti-harmonic reactors in series.In the environment where the harmonic content is not serious,please increase the capacitor voltage,etc., (Common harmonic sources are:frequency converter,DC rectifier,inverter,electrolytic plating equipment,intermediate frequency furnace,electric arc furnace,etc.).
B). When the motors fixedly connected with a parallel capacitor,the running current of the capacitor should be less than the no-load current of the motor.
C). When the transformer is no-load,the capacitor should be out of operation.
 3.There is no external discharge resistor or coil,and the capacitor needs to be delayed for morethan3minutes.After disconnecting the power supply,a short circuit discharge must be performed before touching or testing.
 4.In principle,it is not recommended to use a miniature circuit breaker for short circuit protection.It should be selected according to 2-3 times the rated
