ARM6HU Highlights
Insulation Performance
Pole to pole connection and complete isolation of the main circuit.
New Energy Applications
Widely used in the field of new energy. AC MCCB: series inverter application (power station type). The PV string is inverted by the inverter DC/AC, and the output AC is boosted and connected to the grid after being converged by the AC combiner box.
Substation Configuration
AC combiner box and low-voltage side of box substation shall be equipped with AC circuit breaker, with working voltage of AC500V → AC800V. The operating voltage of direct grid connection mode is relatively low, generally less than AC400V.
ARM6hu
Frequently Asked Questions (FAQ)
Q: What is the insulation design of the ARM6HU?
The ARM6HU features a pole-to-pole connection design that ensures complete isolation of the main circuit.
Q: In which fields is the ARM6HU mainly applied?
The products are widely utilized in the new energy sector, particularly in AC MCCB series inverter applications for power stations.
Q: How does the ARM6HU function in PV string systems?
The PV string is inverted by the DC/AC inverter, after which the output AC is boosted and connected to the grid once converged by the AC combiner box.
Q: What is the working voltage range for the box substation and AC combiner box?
They are designed to be equipped with AC circuit breakers operating at working voltages ranging from AC500V to AC800V.
Q: What is the typical operating voltage for the direct grid connection mode?
For the direct grid connection mode, the operating voltage is relatively low, generally staying below AC400V.
