Description
Technical Field
The utility model relates to a signal prompt structure of a leakage current sensor, which is used in the field of lightning arrester fault detection.
Background
The existing arrester leakage current sensor is installed in a semi-permanent connection mode with the arrester. Although the current lightning arrester leakage current sensor can monitor the working state of the lightning arrester in real time and send an alarm prompt to a monitoring background for the lightning arrester which generates electric leakage and other abnormal working states, the fault lightning arrester is accurately positioned and identified due to the large number of the field lightning arresters, so that the replacement operation still has great difficulty, a large amount of manpower and time are required for the search work of the fault lightning arrester, and the efficiency is low.

Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific examples:
referring to fig. 1, a signal prompt structure of a leakage current sensor according to the present invention includes a leakage current sensor 1 and a signal prompt device 2.
The leakage current sensor is divided into an acquisition end 11 and a measurement end 12. The acquisition end 11 is provided with a wiring terminal, the measurement end 12 is provided with a connecting structure matched with the wiring terminal, and the two are detachably connected with each other in a combined manner. When the lightning arrester is installed, the acquisition end 11 and the lightning arrester 3 are integrally connected, and then the measurement end 12 is connected with the acquisition end in a pluggable mode. The current monitoring circuit is arranged in the acquisition end 11, the signal detection assembly is arranged in the measurement end 12 and comprises a signal reading module and a signal transmission module, and the signal transmission module is in signal receiving and transmitting with the remote monitoring background.
The surface of the measuring end is provided with a prompting device clamping groove, the signal prompting device 2 is detachably installed in the prompting device clamping groove in an embedded mode, and a pin of the signal prompting device 2 is connected into the measuring end and is connected with the signal transmission module. The signal prompting device is a red LED signal prompting lamp, and a buzzer alarm can be additionally arranged to be used for sound signal prompting. When the lightning arrester breaks down or the leakage current reaches a critical threshold value, the red LED warning lamp flickers according to a design cycle to prompt, so that the warning effect is achieved, maintenance personnel can conveniently patrol and search, and the fault area can be conveniently determined. When the LED lamp emits light, the power consumption is only 0.01mW, the service life can reach 10 ten thousand hours, and the reliable connection and sealing between the measuring end of the monitor and the LED lamp are ensured through a special packaging process, so that the requirement of outdoor actual operation working conditions is met.
In order to prevent adverse weather from influencing the signal prompt, the signal prompt device is arranged at the bottom of the measuring end, and a shielding effect is provided through a hard shell of the measuring end.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above described embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
