DC current source GDZL-3kA

GDZL-3kA Customized 3000A DC Large Current Generator General Information At present, the DC large current generators produced by most manufacturers are based on the principle of voltage regulators and current rise transformers. The equipment produced by this principle is not tight and large in weight, and the process of rising current is slow and the control precision is low. Very inconvenient for on-site operation. In order to solve the need of DC large current generators on site, HV HIPOT developed a set of instruments suitable for DC large current generators for power system mobile use. Some manufacturers' test and calibration equipment mostly uses analog signals or super capacitor discharge methods to provide test signals for simulation of working state test and calibration. However, the on-state voltage drop of the high-current DC circuit breaker and the switch is not linear, and the test result does not match the actual working state because the operating current cannot be supplied or the stable continuous operating current and the debugging current cannot be provided. The device does not reach the running effect, and there is a security risk. In order to ensure safe operation, some places take replacement measures for suspected switches, circuit breakers, etc., and equipment that can be completely used can be directly scrapped through inspection and calibration, resulting in unnecessary economic losses.
