Description of the crowbar resistor:

Crowbar resistors are mainly used in low voltage traversing technology of wind power inverters. It is used on the rotor side of the wind turbine for bypassing the rotor side converter. When the grid low voltage disturbance occurs, to prevent the DC bus voltage is too high and the rotor current is too large. Mainly working in a fault state. Crowbar resistors can dissipate 80% of the huge energy instantaneously.

Features:

1. Applicable to the harsh operating environment of wind power converter;

2. The use of high-quality nickel-chromium alloy resistance material, heat dissipation, can withstand sustained impact;

3. The use of grid-type trial production, small size, short-term impact energy.

The resistance cabinet is mainly used in common resistor in cranes and similar lifting equipment matching JZR2, YZR series motor, it applies to the AC 50HZ circuit , voltage up to 1140V, working with controller (screen) to control motor starting, speed and braking.
