Product Description

GDZL-3kA DC 3000A  Large Current Generator Hipot Test Set 

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.

GDZL-3KA DC high current generator adopts the main high frequency transformer of nanocrystalline material, and imports high power insulated gate bipolar transistor "IGBT" module as the main power device, high quality material selection ensuring the quality, There is an incomparable superiority of the conventional ordinary DC large current generator. This DC high current device adopts smart quick intelligent power test system (soft dialing number 1010215, trademark registration number 14684481), HV HIPOT company introduces international advanced full bridge phase shift soft switching technology, PWM control, Closed-loop sampling, soft start, over-voltage, over-current, overheat protection ,and output efficiency and accuracy. Small size, light weight makes the power supply can work stably, reliably and safely.

Features
 

1. Display control part adopts Siemens industrial grade PLC controller and 7 inch color LCD touch screen to display clear, friendly, intuitive and anti-interference ability.
2. Positive and negative output electrodes, double-layer 10×120 brass copper row superimposed output, large contact area and small contact resistance, hot fast flow ability.
3. Built-in 8 sets of DC powerful fans, Fast heat dissipation and low noise.
4. The system has constant current, constant voltage and constant power output functions, which is safe and reliable.
5. Complete protection with output over voltage, over current, over power, over temperature protection, when the system is working
6. When an over-voltage, over-current, or over-temperature setting occurs, the system automatically cuts off the output to protect the system.
7. Volume and weight are 1/5-1/10 of the risen mode of the traditional thyristor rectifier and the coupled regulator. Make move, maintenance and installation easy .
8. The whole system adopts IGBT and high-frequency transformer, and the conversion efficiency is greatly improved. Under normal circumstances,SCR devices increase efficiency by more than 50%.
9. The system has a fast response speed, is highly adaptable to grid and load changes, and has high output accuracy.
10. When the grid fault causes the equipment to run out of phase, the system will automatically stop the output.
11. Allow the power supply to change range of 380V±10%, and automatically adjust the pulse width when the grid exceeds the allowable range.
    The device is operating normally.
12. The system software adopts the fast-speed PLC programmable control system developed by HV HIPOT. The system has high scalability and high reliability, which is conducive to maintenance and upgrade.
