2. Equipment function description and technical indicators

 

This equipment is specially developed and produced for railway equipment manufacturers to test the dynamic electrical performance parameters of its isolation boxes, protective boxes, transmission regulators, transformers and other railway equipment. A single device that can test a variety of DUTs. In addition to the obvious test advantages such as fast test speed and stable test, the operating software also reflects the huge advantages of Galaxy Technology in the testing industry. The operating interface is clear and clear. The versatility of the device is greatly enhanced.

 

 

 

Block diagram description:

a) PC: run the system test software, which is the core of the tester, completes the human-computer interaction function, is responsible for the communication with the tester, completes various functional test functions, and displays the test results, etc.

b) SRC communication card: the communication interface between the PC and the tester. Installed in the PC PCI slot.

c) Program-controlled AC voltage source:

Purpose: Provide the required power input to the transformer or isolation box to be tested

Output voltage range: 0~350V programmable and adjustable

Output frequency range: 10HZ~3KHZ

Output current range: 0~15A

Maximum output power: 300W (limit output power 400W)

Among them, the power output step-up transformer parameters are as follows:

 

 

According to the above transformer parameters, the output voltage of the program-controlled power supply is divided into 10 gears, and the output parameters are as follows:

1st gear: voltage: 0~17.7V; maximum current: 0~15A; maximum power 0~300W

2nd gear: voltage: 17.7~25V; maximum current: 12A; maximum power 212W~300W

3rd gear: voltage 25~35.4V; maximum current: 8.49A; maximum power 212W~300W

4th gear: voltage 35.4~50V; maximum current: 6A; maximum power 212W~300W

5th gear: voltage 50~70.7V; maximum current: 4.24A; maximum power 212W~300W

6th gear: voltage 70.7V~100V; maximum current: 3A; maximum power 212W~300W

7th gear: voltage 100~141.4V; maximum current: 2.12A; maximum power 212W~300W

8th gear: voltage 141.4V~200V; maximum current: 1.5A; maximum power 212W~300W

9th gear: voltage 200V~282.8V; maximum current: 1.06A; maximum power 212W~300W

10th gear: voltage 282.8V~350V; maximum current: 0.75A; maximum power 212W~262.5W

a) Voltage acquisition unit:

Purpose: to collect the input current of the product to be tested; to collect the input and output voltages;

Voltage acquisition range: 0~400V

At the same time, the acquisition channel of the board can be used as the measurement channel of the test lead of the multimeter.

b) Relay contact output, power load switch board:

Purpose: Provide the terminal shorting function for the transformer and isolation box to be tested;

Switch channels: 8 channels/block

Maximum switching voltage: 350V

Maximum switching current: 15A

Maximum switching power: 150W

c) Load resistance output board:

Provide the load resistance for the DUT, which can be controlled by the program.

 

3. Comparative analysis of project import efficiency and manual testing

 

  artificial SRC functional test system
Detection speed 180:600S/PIC 60'180S/PIC
Inspection record No records or manual records Automatically record into the database for easy query and data
backtracking
Inspection quality Manual testing requires connection, etc., there may be
connection errors, and the test time is relatively long, which is prone
to human factors, resulting in missed reports.
Automatically judge according to the settings, without the influence of human factors
Test suitability No unified device can detect all
DUTs
- One system can detect all the tested objects
Detection efficiency Working for a long time, people are easily fatigued, resulting in a
decrease in efficiency and also affecting the quality of inspection
24 hours continuous work

 

Fourth, equipment import cost recovery cycle accounting

project before import after import
Single detection time (seconds) 3 minutes to 10 minutes 1 minute to 3 minutes
8 hours capacity per station 6 to 20 20 to 60
Save 2 to 3 people after importing equipment
