Description

Technical Field

[0001] The utility model belongs to the technical field of electric power equipment, in particular to a digital lightning protection monitoring device. Background Art

[0002] The construction of smart substations is an important part of the State Grid Corporation's construction of a modern equipment management system, an important measure to improve the level of equipment intelligence and the quality and efficiency of substation operation and inspection, and an important foundation for the digital transformation of substations. At present, in the process of promoting the construction of smart substations, four new technologies and applications, namely digital remote metering, one-button sequential control, comprehensive monitoring of main and auxiliary, and remote intelligent inspection, are relatively mature and especially recognized by the grassroots.

[0003] Digital remote transmission meters are one of them. From the perspective of operation and performance, the manual on-site reading of meter readings is a cumbersome, inefficient and repetitive task. Through digital remote transmission, the digital collection and remote transmission of instrument data of the entire station's main equipment will be realized, which will greatly reduce the workload of daily operation and maintenance, effectively reduce the workload of operation and maintenance personnel, and significantly improve operation and inspection performance.

[0004] In the prior art, there is no remote monitoring device for the operation of the lightning arrester, which cannot meet some usage requirements. Summary of the invention

[0005] The purpose of the utility model is to address the above shortcomings and provide a component that can remotely monitor the operation of the lightning arrester and meet the requirements of smart substation construction - a digital lightning protection monitoring device.

[0006] The technical solution of the utility model is implemented as follows: a digital lightning protection monitoring device, characterized in that: it includes a shell, a current transformer is installed inside the shell, the current transformer has a test coil, the shell has a through hole sleeve, the through hole sleeve has a through hole that passes through from top to bottom, the test coil is around the through hole sleeve, the current transformer is connected to an ammeter, and the ammeter is connected to a first signal transceiver; it also includes a second signal transceiver matching the first signal transceiver; the first signal transceiver and the second signal transceiver are connected through a wireless network and can exchange information and data sources, the second signal transceiver is also connected to a data processing unit and a data storage unit, the data processing unit is connected to the data storage unit, the data processing unit can process the data transmitted by the second signal transceiver and obtain information such as the number of discharges and the discharge interval time, and transmit the information to the data storage unit, and the data storage unit stores the information.

[0007] The beneficial effect of the utility model is that such a digital lightning protection monitoring device has the advantage of being able to remotely monitor the operation of the lightning arrester and meet the requirements for the construction of smart substations.

[0012] The present invention will be further described below in conjunction with the embodiments.

[0013] like Figure 1 , 2 As shown in FIG. 3 , a digital lightning protection monitoring device is characterized in that: it comprises a shell 1, a current transformer is installed inside the shell, the current transformer has a test coil 2, the shell has a through hole sleeve 3, the through hole sleeve has a through hole 31 which passes through from top to bottom, the test coil is around the through hole sleeve, the current transformer is connected to an ammeter, and the ammeter is connected to a first signal transceiver; it also comprises a second signal transceiver matching the first signal transceiver; the first signal transceiver and the second signal transceiver are connected through a wireless network and can exchange information and data sources, the second signal transceiver is also connected to a data processing unit and a data storage unit, the data processing unit is connected to the data storage unit, the data processing unit can process the data transmitted by the second signal transceiver and obtain information such as the number of discharges and the discharge interval time, and transmit the information to the data storage unit, and the data storage unit stores the information.

[0014] When the utility model is used, it corresponds to a lightning arrester. The lightning arrester has a lead-out wire. When in use, the lead-out wire is installed through the through hole. The discharge of the lightning arrester will inevitably cause a change in the current of the lead-out wire. The current transformer tests the change in current and transmits this change to the ammeter, so that the number of discharges of the lightning arrester and the value of each discharge can be known, and the signal is transmitted to the first signal transceiver device. The first signal transceiver device transmits this signal to the second signal transceiver device. The second signal transceiver device decodes these through the data processing unit, so that people can understand the operation of the lightning arrester at a distance; at the same time, these data are stored through the data storage unit for easy tracking and historical reference.

[0015] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
