Outline
GZR-10/□-1 /3 Column AC high voltage vacuum compensation box, box with fully enclosed structure, the components are mounted in the housing, the shielding effect is obvious at high altitude snow and sand. Can effectively reduce maintenance times and improve operational efficiency, the compensation box with SDK-11-type high-pressure compensated controller, the compensation controller using single-chip microcontroller chip MCU, I2C memory circuit, A / D AC sampling, V / F voltage frequency conversion, sampling speed, high precision, the software uses fuzzy algorithms, artificial intelligence, switching precision. All electrical parameters can be preset.
Uses
G Z R -1 0/ □-1 /3 Column AC high voltage vacuum compensation tank for 3 ~ 10kV three-phase AC 50Hz power line, substation, for improving the power factor, improve power quality. Outdoor column device can use, but also for indoor installation.
Environment
△ Altitude: not exceed 2500m;
△ maximum temperature: + 45 ℃;
△ minimum temperature: -30 ℃ (outside the household);
△ relative humidity ≤75%;
△ no inflammable gas installation at the air non-conductive dust and corrosive gas around the insulation and metal should be no strong vibration and shock.
