High-Voltage Capacitor

Summary

UEG USA electrical high voltage capacitor for frequency 50Hz / 60Hz AC power system, is mainly used to improve system power factor, improving the power quality, and reduce the circuit loss, improve the transformer efficiency, give full play to the efficiency of power generation, power supply equipment. Is conducive to energy-saving emission reduction, energy saving.

Technical characteristics

Dielectric:

The whole film dielectric high electric strength

Insulating oil:

Using C101 insulation oil, does not containchlorinated biphenyls, safety and environmental protection type insulating oil, conforms to the M/DBT standard. With chlorine free, non-toxic, candissolve the characteristics of biological. Wideapplicable temperature range, good thermal stabilityand excellent electrical properties.

The internal discharge resistance:

In 10 minutes the peak rated voltage is reduced tobelow 75 V (can be customized according to the needsin 5 minutes down to below 50 V), accord with IEC60871-1 standard.

Internal fuse protection:

American electrical capacitor allocation of internalfuse protection so as to prolong the service life ofthe capacitor. When the capacitor component internalbreakdown, capacitor assembly is connected in parallel with the release of energy, the fusebreaking in a few microseconds time formationprotection. Because the fuse for the special design,interdiction of small energy (about 50-200 joule),so the intermittent arc formed within the notcapacitor or produce any gas, no pollution to theinsulating oil.

The fuse can be designed over voltage and overcurrent, capacitor rated switching of the transientcurrent, capacitor other internal fault caused bythe short circuit current or voltage instantaneousseries capacitor group protection gap action caused over and over current. The design accords with the design standard of IEC.

The pressure control switch (optional)

Under the unstable state, the capacitor is prone to failure. When the capacitor fault occurs, the internal pressure increases will lead to burstcapacitors.

The pressure switch can avoid the capacitor suchconditions, when the pressure exceeds the set value,the protection of the pressure switch will passsystem of circuit breaker immediately disconnect thecapacitor group to use, which makes the system more secure.

(Note: requires client installation has the short circuit protection device. In accordance with the IEC standard)

Housing material:

Capacitor shell adopts conforms to the European standard and German standard stainless steelmaterial. With a coating on the capacitor at the top and bottom.

Insulator

With highly reliable strength and the insulation capability of welded insulated porcelain casing tube, according to the project demand supply any connected terminal clamp.

Installation:

Application of vertical or horizontal installation.

  Three-phase high voltage capacitor
