RXGD-3 High-resistance Electric Heating Alloy Rapid Life Testing Machine I. Equipment Overview: This equipment is used for the rapid life testing of high-resistance electric heating alloys in the iron-chromium-aluminum and nickel-chromium series. According to its working principle, the test specimen is placed in a test chamber with stable air flow and no corrosiveness. The test specimen is fixed and powered on. The current and voltage are adjusted for a specified time, and the life of the specimen is determined according to its temperature. II. Standards Compliance: It meets the testing requirements of standards such as GB13300-1991 and GB/T1234-1995. III. Main Parameters: 1) Number of Test Stations: Three independent stations. 2) Adjustable Voltage: Independent output for three stations, 0-50VAC.    Test Current: 0~20A. An alarm current can be set, and an alarm will be issued when the current is lower than the set value. 3) Output Power: The total power of each station is 1KVA. 4) Power-on Time: Can be set from 0 to 999S. 5) Power-off Time: Can be set from 0 to 999S. 6) Number of On-off Cycles: 2 times per minute, with an error of ±10 seconds.    Long-life solid-state relays are used, with a service life of over ten million times. 7) Adjustment Method: Manual voltage adjustment. 8) Specimen Box: The inner wall of the box (200*450*110) is painted black, and the front side is made of 3mm ordinary glass as the observation surface. 9) Safety Mode: The instrument's switch door is equipped with a safety device. When the door is opened, the power is automatically cut off and the test stops. 10) Equipment Appearance: The box body is made of high-insulation acrylic material, and the switch door is equipped with an observation window. 11) Control Method: PLC + 7-inch true color touch screen. 12) Working Power Supply: AC220V, 50Hz. 13) Total Power: 4KW. 14) Equipment Dimensions: 800*800*1800mm.
