General:
JP type outdoor switchboard is an outdoor complete set of power distribution unit of three-phase AC 50Hz and rated voltage of 400V, is applicable to urban and rural power grids, used for control, compensation and metering of output of transformer of 10KV to transformer. It realizes load control, meter reading, remote maintenance, anti-electricity-theft alarm, payment control of electric charge and other functions to circuit, there is air circuit breaker that is used for breaking loads in the switch champer; relative compensation champer is equipped with muti-stage dynamic relative power compensation device that is of surge-free and long survice life, which realizes compensation mode of voltage zero-crossing switch in and current zero-crossing switch off, will not produce over-voltage, it is able to realize multi compensation modes of three-phase wquilibrium and so on. As it integrates the function the functions of electric energy metering with load breaking relative compensation, it is of great advantage to realizeautomated control, and is convenient for installation, it cuts down the investment, is proptitios to be popularized. This outdoor switchboard complies with the standards GB/1.1-2005, gb/15576-2008 and so on.
Sevice conditions:
1.Ambient temperature: -25℃~+50℃.
2.Relative humidity: ≤90%(20℃).
3.Altitude: ≤2000m
4.Inclination of vertical installation: ≤10℃
5.Class of air pollution: III heavy.
