Abstract

The invention discloses a high-power high-stability large-current short-circuit test load cabinet for a new energy power battery. The high-power high-stability large-current short-circuit test load cabinet comprises a cabinet body, knife switches and integrated resistors, wherein the integrated resistors and knife switches are installed in the cabinet body, the integrated resistors are connected with the knife switches in series, a fan is correspondingly arranged below each vertical column of integrated resistors, the fans are installed at the bottom end of the cabinet body, and a heat dissipation screen plate is further installed at the top end of the cabinet body. According to the high-current test load cabinet, the power-on number of the integrated resistors in the cabinet body is controlled through the knife switches, the resistance of the load cabinet is changed, the load is convenient to adjust, and the high-current test load cabinet is suitable for high-current short-circuit test of high-power and high-stability new energy battery; and the integrated resistors have a good insulation effect and a good heat conduction effect, the fans are adopted to blow air to the integratedresistors in each vertical column, and heat emitted by the integrated resistors flows along with the air from bottom to top and is finally led out from the heat dissipation net plate at the top end ofthe cabinet body, so the efficient and rapid heat dissipation effect is achieved, and normal operation of the load cabinet is guaranteed.
