Short-circuit current tester JQ-5000A

battery

The high-current short-circuit test device is designed according to the requirements of various battery short-circuit test standards. According to the standard requirements, the short-circuit device must meet the internal resistance range ≤5mΩ, so as to obtain the maximum short-circuit current required by the test; in addition, the circuit design of the short-circuit device must also be able to withstand The impact of high current, so we chose industrial grade DC electromagnetic contactor and all copper terminal and internal copper plate diversion, wide copper plate effectively improve the heat dissipation effect, make the high current short circuit device safer, effectively reduce the loss of test equipment, ensure The accuracy of the test data. Features •High current DC contacter •Turn the DC working voltage to 660V at a long distance •Rated working current 1000A (or 2000A) DC. equipped with a sériés of magnetic blower cubicite arc extinguishing cover arc extinguishing System; •The overall structure of the plane layout, the electromagnetic System and the main contact arc extinguishing System are respectively fixed on the mounting châssis, and the angled rotating electromagnetic System and the double winding attracting coil are used, and the pressing edge device is added on the rotating corner •The main contact is made of copper. Low contact résistance and fast response •The contactor is reliable, safe, long life and easy to maintain. •Remote control: long distance wireless control •Reliable, stable, anti-interference ability, long life
