Product Introduction

 

For all kinds of relay (such as current, voltage, inverse time, direction, impedance, power differential, low cycle, at the same time, frequency, dc, in the middle, time, etc.) and microcomputer protection for verification, and can simulate various complex instantaneity, permanent, transform fault test for the whole group.

Ii。 Product features:

1. Smart host

The main engine USES high speed high performance digital signal processor, fast speed, bandwidth of transmission band, and the application of double precision algorithm to generate arbitrary high-precision waveform. Because of the integrated structure, the parts are closely combined, the data transmission is short and the structure is compact.

2。 Stand-alone operation

The device is operated by a flexible rotating mouse with a large LCD screen, complete with Chinese display. Live can complete most of the testing work, for a variety of relay (such as current, voltage, inverse time, direction, impedance, power differential, low cycle, at the same time, frequency, dc, in the middle, time, etc.) and microcomputer protection for verification, and can simulate various complex instantaneity, permanent, transform fault test for the whole group.

3. Connect the computer

Through a full set of operation in Chinese software on the Windows platform, can undertake all kinds of large, complex and higher degree of automation of checking work, can easily test and scanning all kinds of protection setting value, can real-time test data storage, display vector diagram, draw the fault waveform, online printing statements, etc.

4. Large-screen LCD display screen

The machine adopts a large-screen high resolution graphics LCD display, all operating procedures are set on the display screen, and the operation interface and test results are all displayed in hanhua, and the display is clear and clear。

5. "idiot" operation

Using the advanced controller to "rotate the mouse", it greatly simplifies the operation part of the structure, the operation is simple, quick and easy to grasp.

6。 New high fidelity amplifier

The output class adopts the new high power module high-fidelity amplifier, which can be used as the output of the current output, the output power is large, the accuracy is good, the reliability is high。

7。 Direct current and voltage output

Phase voltage, phase current adopts dc amplifier output method, can be directly output ac voltage and ac current, dc voltage, dc current,, variable frequency and variable Angle, can be superimposed 1-20 harmonics.

8. Self-protection

The reasonable design of heat dissipation structure is adopted, and it has the reliable and perfect multiple protection measures and the power supply soft start, and a certain fault self-diagnosis and the latching function。

9。 Independent dc power output

The device has 110V or 220V special dc power output.

10. Rich contact

There are 8 contact inputs and 4 empty contact outputs. The input contact is an empty contact and 0-250v potential contact, which can be automatically recognized.

11. Integrated single machine structure of main engine

Use ac 220V power supply. Small volume, light weight, easy to carry, convenient flow test.

12. Cost-effective

It belongs to cross - specialty joint design products, integrated multi - professional advanced scientific and technological achievements。 Both the performance of the large test instrument and the price of the small test instrument have high performance ratio。

Product Parameters

Product Characteristics

Rotate the mouse usage method

The underlying function is similar to the mouse used on a computer. It has three operations: "left-hand", "right-handed" and "press select". Using the mouse's three operations, you can use to move the cursor and modify the data.

The rotating mouse also includes four functional keys: "F1", "F2", "F3",

"F4". F1: thumb operation, switch to the start button of the toolbar. F2:

Finger operation, switch to the first button or TAB of the page。 F3: middle finger operation,

Use to switch the cursor direction in the table. F4: spare function key, mouse structure like right

As shown in figure。

Mobile cursor: when the screen displays the operation interface, it is used to move the cursor position。 When the cursor moves to a certain item, the "press" knob is selected to open or switch this item。 If a certain data item is selected, the modified process of entering this data is changed, and the data is updated and modified with "left hand" and "right hand"。 If an item is open (e。g。, "manual test/automatic test"), then "press" a knob to switch another state。

The data input method of the rotating mouse: each data modification is performed according to the data from left to right. Modify data, move the cursor to the data, press the button to open the selected data items, the cursor will narrow the focus to the left of the data first, then can modify the value and using "left-handed," "right hand" to increase or decrease the value; After changing the first value, press the knob, the cursor will focus to the second value on the left, and then you can enter the change of the value, the same method. Once the data is modified, press the knob again, and the cursor is restored to the shape of the large cursor, which means that the data is modified. The cursor can be removed at this point. .
