Problems solved by technology

However, due to the use environment, the humidity in the air is relatively high, which will cause the electronic components inside the device to absorb moisture, rust and corrode, or even short circuit, making the relay protection device unable to operate normally and affecting its service life
Generally, a sponge is placed at the heat dissipation hole of the relay protection device to remove moisture, but this will also affect the heat dissipation of the device, and the practicability is relatively low. The chemical desiccant is used to absorb moisture, and the staff needs to be replaced frequently on a regular basis Chemical desiccant, the operation is not convenient enough, can not meet the actual practical needs

Abstract

The invention relates to the technical field of relay protection, and discloses an offshore oil platform power grid fault real-time feedback relay protection device comprising an indexing mechanism, and the indexing mechanism comprises a driving rod; the driving rod moves rightwards, so that a storage frame in a charging tray is shifted, the storage frame filled with an unused chemical drying agent is communicated with a communicating pipe, and the storage frame filled with the used chemical drying agent is moved away, automatic replacement of the chemical drying agent is realized, and the relay protection device is continuously dried; the conditions of moisture absorption and short circuit of internal components of the relay protection device are effectively avoided, normal operation of the relay protection device is guaranteed, a sliding plate is close to a left clamping plate, a tooth-shaped wheel rotates clockwise by 180 degrees, the chemical drying agent in the storage frame are separated from the charging tray, the used chemical drying agent is automatically cleaned, manual cleaning is omitted, the chemical drying agent can be conveniently supplied, the operation is convenient and fast, the automation degree is high, and the actual use requirements are better met.

Description

technical field [0001] The invention relates to the technical field of relay protection, in particular to a relay protection device for real-time feedback of power grid faults on offshore oil platforms. Background technique [0002] With the development of the power system, the structure of the power grid is becoming more and more complex, and the short-circuit capacity is constantly increasing, so the relay protection device comes out. Relay protection is an important measure to detect faults or abnormal conditions in the power system, thereby sending out alarm signals, or directly isolating and removing faulty parts. It is widely used in various industries, such as offshore oil production. Due to the scattered distribution of offshore oil extraction points, a huge power grid is required to control the situation of each oil extraction point. In order to facilitate monitoring of the power grid, it is necessary to use relay protection devices to monitor its operation in real ...
