Talking about the Use of Microcomputer Relay Protection Tester
Microcomputer relay protection tester is an important test tool to ensure the safe and reliable operation of the power system. It can use stand-alone operation, can also be connected to other computer advanced structure. It can be operated independently or as a laptop. Powerful operation, small size, high precision, advanced features, and small tester is compact and flexible, easy to operate, high reliability, high performance and price ratio. Widely used in line protection, main transformer differential protection, excitation control and other fields.
Relay protection test equipment is divided into two loops: the main loop and the auxiliary loop. The main loop adopts a large knob to adjust, the auxiliary loop uses a small knob to adjust, the main loop controls the output of the output through the panel "output selection" button switch, and Each time you switch one output, the digital voltage/amplitude meter on the instrument automatically monitors its output value. The auxiliary circuit controls the output directly through the output switch control. The measurement can be externally attached to the multimeter.
Microcomputer Relay Protection Tester Notes
1. The tester unit has built-in IPC and Windows operating system. Do not switch the power of the host too frequently.
2. The device panel or back panel is equipped with a USB socket, allowing hot plug USB devices (such as U disk, etc.), but note that it must be done after the data transmission is completed.
3. The device is equipped with a dedicated self-recovery CF card to prevent damage to the operating system due to illegal shutdown, deletion or modification of files on the hard disk and icons on the desktop. If you really need to store data in this unit, please save the data in the D drive. When using a USB disk to copy data, make sure that the USB disk is clean and virus free. Please do not use U disk to install other software programs in this system.
4. When connecting an external keyboard or mouse, do not insert the wrong port. Otherwise, the Windows operating system cannot start normally.
5. Do not turn off the power directly in the output state to avoid incorrect operation due to incorrect output during shutdown.
6. The input quantity is compatible with the empty contact point and potential (0~250VDC). When the live contact is used, the high-side (positive) of the contact potential should be connected to the COM terminal of the common terminal.
7. When using this instrument, do not block or close the ventilation openings of the body. Usually, place the instrument in a standing position or open the support legs slightly.
8. It is forbidden to introduce external AC and DC power to the voltage and current output jacks of the tester. Otherwise, the tester will be damaged.
9. If there is strong on-site interference or high safety requirements, before testing, ground the power cable (3-core) ground or the grounding hole of the device.
10. If there are problems such as interface data error or device connection failure during use, you can solve this: Press the reset button button down to reset the DSP, or exit the operation program to return to the main menu and rerun the program. The data is restored to the default value.

Galvanized coil, dip a sheet steel plate into a melted zinc tank, so that the surface adhesion of a zinc sheet steel. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously dipped in the melting zinc bath to make Galvanized Steel plate; Alloyed galvanized steel plate. This steel plate is also made by hot dipping, but immediately after it is out of the groove, it is heated to about 500℃ to create an alloy coating of zinc and iron. This galvanized coil has good coating tightness and weldability
