Fully Automatic Temperature Rise Test DeviceZC-510WS-500A

ZC-510WS-500A fully automatic temperature rise test device mainly consists of a fully automatic temperature rise test system, a rising transformer, an induction regulator, a temperature control inspection system, etc. It is a necessary equipment in various industries that requires high current places for electrical debugging, and it is also a universal equipment for temperature rise testing of various types of high-voltage switches. It can be used for primary busbar protection and current transformer ratio testing in power systems, as well as for setting current relay and switch travel time, overcurrent interruption, transmission and other tests. Widely used in power plants, substations, switchgear production testing, electrical manufacturing plants, scientific research, laboratories and other units, it belongs to short-term or intermittent working system. The fully automatic temperature rise test device has the characteristics of small size, light weight, good performance, and easy use and maintenance.

Features and Advantages

1. It has zero start protection function.
2. The experiment time is set independently and has a reminder function.
3. After setting the current, deviations can be automatically adjusted separately.
4. The power supply and output current are displayed using computer software with an accuracy of level 0.5.
5. Electric control of voltage rise and fall to achieve control of output current, with optional control accuracy.
6. Industrial grade industrial computer control. The fully automatic intelligent control system does not require manual intervention for testing.
7. The system comes with input voltage values and displays active power in real-time.
8. After setting the temperature rise range and parameters, the device automatically maintains the output current value. And it has adjustable current error function.
9. Equipped with 16 temperature monitoring, measurement, and recording functions (expandable), it can automatically test the ambient temperature, compare the temperature at the testing point to form a temperature rise, and automatically alarm when the set temperature is exceeded. You can access the temperature and temperature rise at any point, with a measurement error of ± 1%.
10. The accuracy level of the current transformer is 0.5.
Attention: Please ground the instrument reliably before testing to ensure test safety!!!
