Safety Precautions (1) For the safety of operators and instruments, ensure good grounding of the instruments. (2) When preparing for the experiment, the ground wire should be connected first. After the work is completed, the ground wire should be removed last. (3) The power supply connected to the instrument is required to withstand a 5A current surge.
I.Overview 1.Purpose The HZDL-1000A three-phase high current generator (referred to as three-phase current regulator) is a testing equipment independently developed by our company. It combines the advantages of similar products at home and abroad, adopts CNC technology, and has strong anti-interference ability. Compared with the previous generation of current regulators, it has the advantages of large output power, small size, and light weight due to the use of low-power, high-capacity electronic voltage regulators and converters made of high permeability iron cores.
(5)The capacity of this device is designed for short-term operation of 1 minute. If used for batch testing, the working time should be less than 2.5 minutes. Wait for 10 minutes before proceeding to the next operation. If conducting temperature rise (30 minutes to 24 hours), it should be prepared according to long-term working temperature rise.
III. Operational Principle 1.Principle Diagram 2.Operational Principle The instrument measurement circuit includes three current measurement circuits. (Voltage testing can be increased as required) Expandable volt ampere characteristic function. The current measurement circuit includes a micro current zero impedance CT, a programmable amplification circuit, and a sampling circuit.
automatic timing function is achieved by comparing the measured voltage signal amplitude with the set voltage value. Based on the current ratio relationship, the output current of the device can be calculated. The overcurrent protection function is achieved by comparing the measured current/voltage signal amplitude with the set value. IV.Panel Description 1.
products should be able to be transported by road, rail, or air. During transportation, it is not allowed to place it in an outdoor vehicle box. The warehouse should pay attention to rain, dust, and mechanical damage prevention. 2. Storage The instrument should be stored indoors with an ambient temperature of -20 ℃...
