What are the product features of the 10KV line fault indicator?

The 10kV line fault indicator is used for 10kV distribution overhead lines, and has the function of flop indication when grounding or short circuit occurs.

With the continuous improvement of the living standards of urban and rural residents, the dependence on electricity and the power quality requirements have also increased, which puts forward higher requirements for the power supply capacity and power supply quality of the line. The distribution line is the terminal of the power system, is an important part of the power system, directly facing the user end, and people's lives are closely related, therefore, the distribution network line fault has attracted more attention. However, due to the many points, wide area, long line, complex path, uneven equipment quality and other reasons of distribution network lines, it is difficult to find specific fault points.

The installation of 10kV line fault indicator can quickly determine the short circuit and ground fault section, shorten the power outage time, and reduce the scope of power outage, which is not only an important measure to improve the reliability of power supply, but also an indispensable technical force for the construction of intelligent power grid.

The 10kV line type fault indicator has the following product features:

1.high-precision real-time sampling technology;

2.Excellent ultra-low power consumption and power management technology;

3.Intelligent line fault detection and diversified recovery methods;

4.Diversified line condition indication function and operation information;

5.Grounding transient waveform recording and high-precision wireless synchronization technology.

If it is an i-stage overcurrent operation, it first indicates that the fault point is within the protection range of this level. This is usually a short circuit between phases, or at least a metallic ground fault occurs at the same time as both phases. Because the neutral point of the domestic 10kV line is not grounded, the single-phase grounding will not produce grounding current.

The main case is a phase-to-phase short circuit, but the specific judgment of whether it is a phase-to-phase short circuit or grounding also depends on other criteria, such as voltage and negative sequence current.

So far, China's power grid structure is complex and diverse, the generation of line fault indicators is also various, Telicon fault indicators are divided into two categories: one is a cable-type fault indicator, mainly used in power cable lines, ring main units, branch boxes and other cable systems, subdivision can also be divided into panel fault indicator, cable line fault indicator, LCD panel fault indicator, etc.; The other is the overhead line fault indicator, which is subdivided into an intelligent grounding short-circuit fault indicator, which is installed on the overhead power line and is used to detect the grounding and short-circuit fault functions of the line.

Hello, happy to answer for you :

The cable line fault indicator is mainly installed on the power cable line, used to monitor the operation status of the line, Telikang has a fault indicator with communication function, which can monitor the remote measurement of line load current, temperature, etc., with line temperature monitoring and remote transmission function, and can also monitor the zero sequence fault, short circuit fault, switch and other remote signals of the line, and can distinguish between permanent faults and transient faults, and can also control the automatic reset of the fault indicator and other functions.

Installed in the middle of long lines and at branch entrances: Fault sections and fault branches of the line can be indicated.

Installed at the outlet of the substation: it can be determined that it is an in-station or off-site fault.

Installed at the high-voltage inlet line of the user's distribution transformer: it can determine whether the fault is caused by the user.

Installed at the connection between the cable and the overhead line: it can distinguish whether the fault is in the cable section or not.
