Embodiment Construction

[0029] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0030] The grounding wire of a substation is the lifeline for protecting workers in field work. However, in recent years, there have been many vicious misoperation accidents involving switching on with the grounding wire. The substation ground wire real-time collection device provided in the embodiment of the present application can collect the numbers and positions of the ground wir...

Abstract

The application is applicable to the technical field of electric power automation, and provides a real-time acquisition device of a transformer substation ground wire. The device comprises: a collection unit configured to collect ground wire information in use in a transformer substation; a control unit configured to control ground wire information sent by the collection unit and generate execution information according to the ground wire information; and a protection unit configured to receive the execution information sent by the control unit and protect the ground wire in use in the transformer substation according to the execution information. The real-time acquisition device of the transformer substation ground wire provided by the embodiment of the invention adopts the collection unit to collect the ground wire information in a use state in the transformer substation in real time and adopts the control unit to control the corresponding protection unit of the ground wire in use toperform real-time protection of the ground wire in use so as to avoid switch-on of a disconnecting link or a circuit breaker on the ground wire in use due to misoperation, improve the reliability ofthe monitoring of the ground wire in the transformer substation and facilitate improvement of the safety of the operation work.

Description

technical field [0001] The application belongs to the technical field of electric power automation, and in particular relates to a real-time acquisition device for substation ground wires. Background technique [0002] The ground wire of the substation is the lifeline to protect the workers in the field work. At present, at the substation operation and maintenance work site, paper manual records are generally used to record the installation and disassembly of the substation grounding wire under maintenance. Due to the nature of shift work in substations, the power outage personnel and the restoration personnel are often not the same group of people. When the construction time is too long, once the power outage personnel forget to fill in the grounding wire registration record, there is a risk of missing the grounding wire when the power transmission personnel resumes operation and resumes power transmission. Contents of the invention [0003] In view of this, the embodim...
