Five key installation considerations for fire inspection cabinets

The fire inspection cabinet is a functional cabinet for fully automatic inspection of fire pumps. To prevent issues such as long-term idle fire pumps, rust, and abnormal operation of the pumps, the fire inspection cabinet uses low-frequency inspection of the fire pumps. During inspection, the motor runs at 300 RPM, with no increase in the chilled water system and no starting current, which greatly extends the lifespan of the equipment.

The main function of the photovoltaic grid connection cabinet.

During operation, the photovoltaic grid-connected cabinet may experience fluctuations in grid-side voltage, frequency, and other aspects, which can impact the station, leading to phenomena such as excessive load. This not only poses a risk of damage to grid equipment but also threatens the safety of maintenance personnel. The issue of harmonics is a major problem in photovoltaic power generation. Photovoltaic power generation uses AC and DC inverters, and since inverters operate through the switching on and off of semiconductor power switches.
