Problems solved by technology

In order to grasp the operation status of the arrester in time, the current method is mainly to use the leakage current measurement of the arrester to carry out regular inspections. Because the circuit line is high from the ground, the operation during the measurement is cumbersome. Perform live operation
This method needs to invest a lot of manpower and material resources during the measurement period, which is time-consuming and laborious; in addition, due to the long measurement period, it is impossible to detect and diagnose the faults that occur during the interval in time

Embodiment Construction

[0039] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication also changes accordingly.

[0040] In addition, in the present invention, descriptions such as "first", "second", "one" and so on are only for descriptive purposes, and should not be understood as indicating or implying their relative importance or implicitly indicating the indicated technical features quantity. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of these features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

Abstract

The invention belongs to the technical field of electrical equipment detection, and provides a lightning arrester state acquisition device comprising a voltage collector, a middle protection layer and a protection assembly; the middle protection layer is arranged below a voltage collector and connected with the voltage collector in an abutting mode, a signal processing unit is arranged in the middle protection layer, and the signal processing unit is electrically connected with the voltage collector; and the protection assembly is arranged below the middle protection layer in an abutting mode, the current collector is arranged in the protection assembly, and the current collector is electrically connected with the signal processing unit. The device has the advantages that the device can be installed beside a line lightning arrester under the condition of uninterruptible power supply, the line voltage and leakage current of the lightning arrester are monitored in real time, and a sampling signal is processed and then output, so that an operator can master the working state of the lightning arrester in time, and safe operation of a power line is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electrical equipment detection, in particular to a lightning arrester state acquisition device. Background technique [0002] Lightning arrester is a kind of power safety equipment that protects power lines from lightning strikes, and its performance has an important impact on the safe operation of power lines. In order to grasp the operation status of the arrester in time, the current method is mainly to use the leakage current measurement of the arrester to carry out regular inspections. Because the circuit line is high from the ground, the operation during the measurement is cumbersome. Perform live operation. This method needs to invest a lot of manpower and material resources during the measurement period, which is time-consuming and labor-intensive; in addition, due to the long measurement period, the faults that occur during the interval cannot be detected and diagnosed in time.
