The DC load banks is designed for deep discharge maintenance and capacity detection of battery packs. It is simple to operate and easy to move. It can be applied to various power plants, communication base stations, substations, and battery manufacturers, and is suitable for various types and specif......

1. Short-time working system (single braking) t: For the short-time working system of the braking resistor box, it refers to the time required for the resistance to not reach the maximum temperature rise of 63.3% after the rated power is applied. 　TB≤τ=200s

The synthetic wound high voltage resistors are RHR series high-power high voltage resistance devices. This resistor is mainly used in high-voltage circuits such as equipment and instruments as fixed resistances such as bleeder, voltage divider, filter and load.

Aluminum shell resistor, the shell is made of aluminum alloy (gold aluminum case), the surface has heat dissipation grooves, small volume, high power, high temperature resistance, strong overload capacity, weather resistance, high precision, standard low induction resistance, high stability, strong ......

Wire wound resistor series is one of the more commonly used resistors. The resistor body of wire wound resistor is resistance wire. The resistance wire is wound around the ceramic skeleton, the leads are connected, and the surface is coated with a layer of glass glaze or insulating paint.

The neutral point grounding methods commonly used in my country's power system are: the neutral point is directly grounded, the neutral point is not grounded, the neutral point is grounded through the arc suppression coil (resonance grounding), and the neutral point is grounded through the resistanc......
