山东高压变频器维修:今天给大家带来的资讯介绍是高压变频器的接线步骤,我们快来一起了解一下吧!

Maintenance of Shandong High Voltage Inverter: Today's introduction to you is the wiring steps of high voltage converter, let's get together to solve it!

一、山东高压变频器维修介绍主电路的接线

I. Maintenance of Shandong High Voltage Inverter Introducing Wiring of Main Circuit

1、电源应接到高压变频器输入端R、S、T接线端子上,一定不能接到高压变频器输出端(U、V、W)上,否则将损坏高压变频器。

1. The power supply should be connected to the R, S and T terminals of the input end of the high-voltage converter. It must not be connected to the output end of the high-voltage converter (U, V, W), otherwise the high-voltage converter will be damaged.

2、在端子+,PR间,不要连接除建议的制动电阻器选件以外的东西,或绝对不要短路。

2. In the terminal +, PR, do not connect anything other than the recommended brake resistor selection, or never short circuit.

3、电磁波干扰,高压变频器输入/输出包含有谐波成分,可能干扰高压变频器附近的通讯设备。因此,安装选件无线电噪音滤波器FR-BIF或FRBSF01或FR-BLF线路噪音滤波器,使干扰降到最小。

3. Electromagnetic interference. The input/output of high-voltage converter contains harmonic components, which may interfere with communication equipment near high-voltage converter. Therefore, install the selected radio noise filter FR-BIF or FRBSF01 or FR-BLF line noise filter to minimize interference.

4、长距离布线时,由于受到布线的寄生电容充电电流的影响,会使快速响应电流限制功能降低,接于二次侧的仪器误动作而产生故障。

4. In long distance wiring, due to the parasitic capacitor charging current, the fast response current limitation function will be reduced, and the instrument connected to the secondary side will malfunction.

5、在高压变频器输出侧不要安装电力电容器,浪涌抑制器和无线电噪音滤波器。

5. Do not install power capacitors, surge suppressors and radio noise filters on the output side of high voltage converters.

6、为使电压降在2%以内,应使用适当型号的导线接线。

6. In order to make the voltage drop less than 2%, appropriate type of wiring should be used.

7、运行后,改变接线的操作,必须在电源切断10min以上,用万用表检查电压后进行。

7. After operation, the operation of changing wiring must be done after the power supply is cut off for more than 10 minutes and the voltage is checked by a multimeter.

二、山东高压变频器维修介绍控制电路的接线

2. Introduction to Maintenance of Shandong High Voltage Inverter and Connection of Control Circuit

1、控制电路端子的接线应使用屏蔽线或双绞线,而且必须与主回路,强电回路分开布线。

1. The terminal of the control circuit should be connected with shielded or twisted pair wires, and must be separated from the main circuit and the high-voltage circuit.

2、由于控制电路的频率输入信号是微小电流,所以在接点输入的场合,为了防止接触不良,微小信号接点应使用两个并联的节点或使用双生接点。

2. Because the frequency input signal of the control circuit is a small current, in the case of contact input, in order to prevent bad contact, two parallel nodes or twin contacts should be used for micro-signal contacts.

3、控制回路的接线一般选用0.3~0.75平方米的电缆。

3. The cable of 0.3-0.75 square meters is usually used in the connection of control circuit.

三、山东高压变频器维修介绍地线的接线

3. Shandong High Voltage Frequency Converter Maintenance Introduction Ground Wiring Connection

1、由于在高压变频器内有漏电流,为了防止触电,高压变频器和电机必须接地。

1. Because of leakage current in high voltage converter, in order to prevent electric shock, high voltage converter and motor must be grounded.

2、高压变频器接地用专用接地端子。接地线的连接,要使用镀锡处理的压接端子。

2. Special earthing terminal for grounding of high voltage frequency converter. The connection of grounding wires should be made by pressing terminals treated with tin plating.

3、接地电缆尽量用粗的线径,必须等于或大于规定标准,接地点尽量靠近高压变频器,接地线越短越好。

3. The grounding cable should be as thick as possible, and the grounding point should be as close to the high voltage converter as possible. The shorter the grounding line, the better.
