AKMJ-YF, a low voltage filter capacitor with a profit peak

Product introduction

My company produces the product is the key component in the low pressure filter system, the use of the metal - oriented polypropylene film, the special coating process, the cylindrical shell structure. Can effectively filter out the harmonics in power system, both reactive power compensation effect.

Characteristic

AKMJ-YF series cylindrical low voltage filter capacitor, it is our company independent research and development of low voltage shunt capacitor based on another innovation, the filter capacitor in the internal structure and explosion-proof, on the flow of the use of a unique, new design concept, so that the filter capacitor is smaller, lighter, more safe, longer life.

1, high reliability, due to the special design of the harmonic current deposit form and thickness. Life reached 100000 hours.

2, the explosion-proof performance is excellent, the unique roof type explosion-proof structure, the capacitor failure is only for open circuit.

3, the terminal is novel, easy connection and the capacitor, such as the combination of 15KVar can be used as a combination of any 15 of the capacity, with 10KVar and 12KVar capacitor combination into 22KVar capacitor.

4, volume and weight greatly reduced, only the equivalent of the old 1/3.

5, beautiful appearance, easy installation, aluminum shell, never rust.

6, the capacitor unit does not contain oil, liquid oil casing, combines the advantages of oil immersed capacitor and dry-type capacitor.

Use

Mainly used in low voltage power distribution system for improving the harmonic components in the power grid, improve power quality.

Note

Cylindrical capacitor for roof explosion-proof structure, wiring terminal capacitance is strictly prohibited with copper, aluminum row connection, must use the soft copper wire

According to the working condition of the harmonic content of the special harmonic channels, such as the 3, the 5, the 7 harmonic channels. Capacitance of this capacitor current value is by the harmonic content of the maximum value is determined, the capacitor must meet the conditions of the actual harmonic value under the long-term work is capacitance of conductor to meets with the requirement of the harmonic current value, and also meet the harmonic voltage of the required pressure index, and Jibojia harmonic components of the expression of the total reactive power.

Product selection guide

The filter circuit of the filter circuit should be the fundamental current, harmonic current, harmonic frequency, rated capacity, with this issue can be the company with our engineers to negotiate, we can tailor the amount of customers. Such as the use of traditional reactive power compensation capacity is less than or equal to 20% nonlinear systems, such as in the 20% ~ 50% need to install filter reactor. If > 50%, the filter should be installed. In general, the harmonic in the power grid is 5, 7 times, the use of 7% of the reactor can solve the problem. To 3 of the reactor with 13% ~ 14%. 13, the 11 harmonic generally uses 5.67% of the reactor.
