Power capacitor manufacturer in this paper, the service life of the product

Under the condition of normal, capacitor capacity drop 10 - every year

12%, capacity loss as the operation of the capacitor increases year by year.

Therefore, if there is a long operating life,

More than 4 years)

Capacitor of the enterprise, it is suggested that the best replacement of the new capacitor.

Otherwise, the capacity is too low will affect the compensation effect of capacitor, and as the deterioration of medium, its reliability will be reduced.

How to replace the power capacitor power capacitor is broken? 

 Below we look at how to solved the problem of electric power capacitor replacement first to check the damaged capacitor rated capacity and how much is the rated voltage, low voltage zero.

4 system capacitance pressure generally 0.

44 kv, 10 kv high pressure system of capacitance 11/3 square root, choose different manufacturers and consider fixed hole shape and position; 

 1, the low pressure system power switch controller, separating device master switch, wait for 20 minutes after the safest, a capacitor inside has a discharge resistor.

Wear protective gloves removal of capacitance.

More troublesome, high pressure system outage capacity tank contactor of each circuit, and the fault control capacitor tank circuit breaker, isolating switch capacitance ark, used to capacitor after discharge, discharge rod hanging grounding line;

2, change with the voltage level and capacity; 

 The main switch with electric (

Low voltage system)

You have a guardian.

If 3, capacitance in capacity is bigger, the branch switch and a large wire cable has to change.

4, after changing the capacitance testing screw firmly, shaking table and the multimeter is used to inspect the insulation and have short circuit problem.
An increasing dependence on the use of refrigerant gas start capacitor suppliers has made numerous changes in the start capacitor suppliers industry over the past decades.
