Short circuit current withstand testing machine

Short circuit current withstand testing machine

1、 Overview:

10000ATemperature rise test deviceIt is a specialized equipment designed and manufactured specifically for electrical equipment testing such as current load testing, temperature rise testing, and detecting the maximum breaking current breaking capacity of switches for various current transformers and other electrical equipment in the power sector and factories and mines.
This series of products adopts an integrated structure based on product volume and weight, with features such as infinite adjustment of output current, balanced current rise, wide range of load changes, reliable operation, easy operation, and safety. It is an ideal equipment for conducting flow or temperature rise tests in industrial and mining enterprises.

2、 Main technical parameters:

noteIn the rated output of the current converter, the three-phase output is connected in a Y-shape

3、 Usage environment:

1. Working power supply: 380V ± 10% 50HZ
2. Environmental temperature: -10 ℃ -40 ℃
3. There should be no areas around the product where gas vapor, chemical deposits of dust, dirt, or other explosive media can seriously affect the insulation of transformers.

4、 Working principle:

After being powered on, this series of products adjusts the output voltage of the voltage regulator to obtain the high current required for the test. The working principle diagram is as follows:

5、 Usage and precautions:

1. Connect the working circuit according to electrical principles. The casing of the riser must be well grounded.
2. Connect the power supply (the power terminals are located on the instrument's rear terminal blocks L1, L2, L3, N), turn on the switch, and the red indicator light on the control panel will light up.
3. Click on 'Click here to enter testing' in the main interface to enter the second interface, click on parameter settings in the second interface to enter the third interface, set the current value and time, then return to the second interface and click 'Start testing' to conduct the experiment;

When there is an error between the three-phase current values and the set values, the buttons in Figure 4 can be used to fine tune the current values of each phase.

Temperature rise test bench

SLQA temperature rise test bench is a device used to test the temperature rise of electrical equipment or electronic components during operation.

Its technical parameters include the following aspects:

1.Temperature range:SLQThe temperature rise test bench usually has an adjustable temperature range, which can be adjusted according to the testing requirements. The common range is-70℃ to+200℃。

2.Temperature uniformity:SLQThe temperature rise test bench should have good temperature uniformity, that is, the temperature difference at various positions inside the equipment should be as small as possible, generally requiring a range of ±2Within ℃.

3.Heating rate:SLQThe temperature rise test bench should have a fast heating rate in order to quickly reach the set temperature, generally requiring a heating rate of5℃/minThe above.

4. Temperature control accuracy:SLQThe temperature rise test bench should have high temperature control accuracy, which means it can accurately control the temperature of the equipment. Generally, the temperature control accuracy is required to be within ±1Within ℃.

5.Cooling method:SLQThe temperature rise test bench usually has multiple cooling methods, such as natural cooling, air cooling, water cooling, etc., to meet different testing needs.

6.Security performance:SLQThe temperature rise test bench should have good safety performance, including over temperature protection, leakage protection, short circuit protection and other functions, to ensure the safety of the testing process.

7.Control method:SLQThe temperature rise test bench can be controlled by computer, touch screen, etc., so that users can easily operate the equipment and adjust parameters.

5. The above isSLQSome common technical parameters of temperature rise test bench, different modelsSLQThe temperature rise test bench may vary, and the specific parameters need to be determined based on the actual product.
