The change of 10kV distribution lines power supply mode has strengthened the insulating level of distribution lines, has reduced the trip rate of distribution lines, has improved the power supply reliability, has reduced the line loss. However, in actual operation, a new power supply mode is adopted, so that single-phase earth faults frequently occur, and particularly, the earth faults frequently occur under severe weather conditions such as strong wind, rainstorm, hail, snow and the like, so that the safe and economic operation of the power transformation equipment and the power distribution network is seriously influenced. Therefore, the line single-phase ground fault indicating device is generated according to the requirements of the power system.
However, the existing line single-phase earth fault indicating device has certain disadvantages when in use, and firstly, when the fault indicating device detects a fault, the observation is not intuitive enough for an operator; secondly, in the using process, phenomena such as water seepage or electric leakage and the like may occur, which causes great loss and poor safety.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome fault indication device when detecting the trouble, need set up the mounting hole on the angle steel, to operating personnel, observe directly perceived inadequately, and probably take place infiltration, electric leakage scheduling problem, and provide a 10KV circuit single-phase earth fault indicating device.
The utility model adopts the technical proposal that:
a10 KV line single-phase earth fault indicating device comprises a rectangular shell with a hollow interior, wherein a protective door for opening or closing the shell is arranged on the shell, and a handle is further arranged on the protective door; a fault detection module, a communication module and a GPS positioning module are arranged in the shell, and the communication module and the GPS positioning module are connected with the fault detection module; the shell is internally provided with an indicating module connected with the fault detection module, a red indicating lamp and a green indicating lamp are arranged on the outer surface of the protective door, and the indicating module is respectively connected with the red indicating lamp and the green indicating lamp; and waterproof layers and insulating layers are further arranged on the inner surface of the shell and the inner surface of the protective door.
The outer surface of the upper end of the shell is provided with two hanging plates, and the hanging plates are provided with fixing holes convenient to hang.
And detachable supporting legs are arranged at four corners of the outer surface of the lower end of the shell.
The utility model has the advantages that:
1. the utility model discloses an indicating lamp on indicating module and the shutter surface can observe directly perceivedly whether 10KV single-phase ground connection circuit exists the trouble.
2. The utility model is provided with the protective door, the waterproof layer and the insulating layer, so that the protective door forms the first protection in the use process of the fault indicating device, and the shadows of foreign matters and the like to the internal components of the equipment are prevented; the waterproof layer forms a second protection layer and completely isolates the influence of factors such as rainwater on internal components of the equipment; the insulating layer forms a third protection, and accidents such as electric leakage and the like possibly generated in the equipment are effectively prevented.

Detailed Description
The technical solutions in the embodiments of the present invention will be described, clearly and completely, and the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments, in the accompanying drawings of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1-3, the utility model relates to a 10KV line single-phase earth fault indicating device, which comprises a rectangular shell with a hollow interior, wherein a protective door for opening or closing the shell is arranged on the shell, and a handle is also arranged on the protective door; the shell is internally provided with a fault detection module, a communication module and a GPS positioning module, and the communication module and the GPS positioning module are connected with the fault detection module.
The shell is internally provided with an indicating module connected with the fault detection module, a red indicating lamp and a green indicating lamp are arranged on the outer surface of the protective door, and the indicating module is respectively connected with the red indicating lamp and the green indicating lamp. When the 10KV single-phase earth fault indicator is used, the 10KV single-phase earth fault indicator is connected with the 10KV line, the green indicator lamp is turned on, namely, the green indicator lamp is in a normal working state, and the red indicator lamp is turned on, namely, the red indicator lamp is in a fault state.
