Product Description

Transformer Switchgear Temperature Rise High Current Test Device

General Information:

DDG Series Primary Current injection Test Set is suitable for current load test and temperature rise test on various circuit breakers, switch gears, CT/PT and others electric equipments. DDG Primary Current Injection Test Set is widely used in power division and industry mining enterprises.

Features:

√ Intuitive reading: This instrument adopts a digital meter head that can directly display the test values of current, voltage, and temperature factor, which is convenient for experimental observation and recording

√ Accurate measurement: With high measurement accuracy and accurate test values

√ Accurate protection function: Fully digitized processing, the setting of overcurrent protection value and timing current are both implemented digitally, making the protection more accurate

√ Operating modes: manual and automatic

√ Intelligence: Automatically generate curves and standard reports

√ Current recovery tracking function: As the current output time increases, the output circuit heats up, the circuit impedance increases, and the current decreases accordingly. At this time, the software will automatically track the current to the set current

√ Automatic control function for temperature rise test: This function is used for temperature rise test. The temperature rise current and time are set, and the software can achieve automatic test without personnel monitoring. After the test is completed, the results are automatically saved

√ Temperature inspection function: 32 temperature inspections can record temperature according to the set sampling time and automatically generate temperature rise curves

√ Switch protection function: This function is mainly used for measuring the overcurrent action current and action time of overcurrent components such as switchgear and thermal relays. The action time measurement method is divided into contact discrimination and current on/off discrimination. (Contact discrimination: It is necessary to connect the instrument back to a normally open or normally closed contact, and the instrument records the action time through the change of the contact. Current on/off discrimination: It is not necessary to connect the instrument back to the action contact, and the instrument automatically detects the presence or absence of current. The current sometimes starts timing, and the timing stops when the current is lost.)

Technical Specifications:

√ Input AC two-phase 380V 50Hz

√ Output single-phase 0-20kA AC high current; The current can be smooth, stable, and continuously adjustable, with an accuracy higher than 0.2 level

√ The output current is a standard sine wave with minimal glitches, better than the required specifications of the power system, and the ripple factor is less than 0.3%

√ Output current mode: True RMS continuously adjustable

√ Output waveform: Standard sine wave

√ Output opening voltage: 10V/15V/20V

√ Current stability: 0.2%

Current waveform distortion: THD 1%

√ Protection settings: overcurrent, overvoltage, overheating

√ The current action time of the tested component can be measured, and the locking action, time normally open, and normally closed contacts can be synchronously recorded for automatic discrimination

√ Time measurement range: 0.01S -99999.99S, accuracy: 0.001S

√ Temperature rise probe: 12/24/48/64 channels

√ Temperature rise range: 10-800 ℃

√ Note: Non standard customization is possible
