电缆识别仪产品简介：

在电缆施工及维护工作中具有重要意义。目前市场上既有针对非运行电缆识别的仪器，也有针对运行电缆识别的仪器，但是在具体使用中，实际电缆现场往往是互相放置压在一起，仪器所使用的卡钳往往无法卡接导致无法进行识别，因此湖北四方国瑞电力控股有限公司研制了一款方便现场操作的柔性线圈电缆带电电缆识别仪。有时因现场没有220V电源，导致无法进行电缆识别工作，因此主机采用锂电池供电，就可以无需电源就进行带电电缆识别检测，对于实际现场操作带来及大便利。

电缆识别仪工作原理：

将电网输入的220VAC电源经电子技术变换为识别所需的大功率特殊信号，此信号通过专用发射钳加在待识别带电电缆的一点，根据电磁感应原理，在该电缆沿线必然产生与发射信号规律一致的感应信号，在测试现场用高灵敏的手持接收机检测测现场所有电缆，根据手持接收机指示即可准确找出所加信号之电缆（即待识别电缆）。

 

电缆识别仪功能特征：

1、罗盘和方向显示：直观显示管线位置和左右方向。

2、跟踪正误提示：电流方向测量，跟踪正误提示，排除临线干扰（部分频率）。

3、深度和电流测量，可显示信号强度历史曲线。

4、全数字化高精度采样处理：稳定可靠，超高灵敏度，接收通频带极窄，抗干扰能力强，能充分抑制邻近运行电缆及管道的工频及谐波干扰。

5、运行电缆探测：高性能发射卡钳，向运行电缆耦合输出信号。

6、电缆/管线鉴别：柔性卡钳（选配件）方便易用，明确给出鉴别结果；听诊器（选配件）可在不方便使用卡钳时使用。

7、接地故障查找：升压器（选配件）可将zui大输出电压提升至1000V，使用A字架（选配件）可定位管线的对地绝缘破损点，无须调零，箭头指示故障点方向。

8、多种探测频率：主动探测和被动探测。

9、发射机多种信号输出方式：直连输出、卡钳耦合、辐射感应。

10、发射机数字功放大功率输出，全自动阻抗匹配，全自动保护。

11、内置可拆卸大容量锂离子电池，欠压自动关机，长时间无操作自动关机。

12、机壳美观坚固、质轻便携。

 

 

 

电缆识别仪简介英文翻译

Product introduction:

It is of great significance in cable construction and maintenance. At present, there are not only instruments for identification of non operating cables, but also instruments for identification of running cables. However, in actual use, the actual cables are often placed and pressed together on site, and the calipers used by the instruments are often unable to be clamped, which makes it impossible to identify. Therefore, Hubei Sifang Guorui Electric Power Holding Co., Ltd. has developed a flexible coil which is convenient for field operation Live cable identification instrument. Sometimes there is no 220 V power supply on site, which makes it impossible to carry out cable identification work. Therefore, if the host uses lithium battery power supply, it can carry out live cable identification and detection without power supply, which brings great convenience to the actual field operation.

working principle:

The 220 VAC power supply input from the power grid is transformed into a special high-power signal for identification through electronic technology. This signal is added to a point of the live cable to be identified through a special transmitting clamp. According to the principle of electromagnetic induction, the inductive signal which is consistent with the law of the transmitted signal must be generated along the cable. In the test site, all cables are tested with a highly sensitive handheld receiver The cable of the added signal (i.e. the cable to be identified) can be accurately found by holding the indication of the receiver.

 

 

Functional features:

1. Compass and direction display: display the pipeline position and left and right directions visually.

2. Tracking correct and wrong prompt: current direction measurement, tracking right and wrong prompt, eliminating temporary line interference (partial frequency).

3. Depth and current measurement can display the signal strength history curve.

4. Full digital high precision sampling processing: stable and reliable, ultra-high sensitivity, extremely narrow receiving passband, strong anti-interference ability, and can fully suppress the power frequency and harmonic interference of adjacent running cables and pipelines.

5. Operation cable detection: high performance transmitting calipers, output signal to running cable coupling.

6. Cable / pipeline identification: flexible calipers (optional parts) are easy to use and clearly give the identification results; stethoscope (option) can be used when calipers are not convenient.

7. Grounding fault finding: the booster (option) can raise the large output voltage of Zui to 1000V, and the A-frame (option) can locate the damaged point of the pipeline insulation to ground without zero adjustment, and the arrow indicates the direction of the fault point.

8. Multiple detection frequencies: active detection and passive detection.

9. Transmitter a variety of signal output mode: direct connection output, caliper coupling, radiation induction.

10. Transmitter digital power amplifier, high power output, automatic impedance matching, automatic protection.

11. Built in removable large capacity lithium-ion battery, automatic shutdown under voltage, automatic shutdown without operation for a long time.

12. The shell is beautiful and solid, light and portable.
