Abstract
The utility model discloses a monitoring and alarming device for arrester degradation, which comprises an alarm sensor and an arrester online monitor, wherein the alarm sensor is connected with a grounding end of an arrester and the arrester online monitor is connected with the alarm sensor. According to the monitoring and alarming device for arrester degradation, the grounding end of the arrester is grounded by passing through the alarm sensor, leakage current information of the arrester is obtained by the alarm sensor and is uploaded to the arrester online monitor, the running state of the arrester is monitored in real time by the arrester online monitor, and the normal use of the arrester is ensured.
Description
Technical field
The utility model relates to lightning arrester monitoring field, specifically is a kind of lightning arrester deterioration monitoring alarm.
Background technology
Progressively development along with intelligent grid; Important leverage-overvoltage protective device (lightning arrester) as electric power netting safe running is essential; But itself is in the protection electrical network, and the safe operation of self is particularly important, and domestic monitoring for lightning arrester does not at present also have widespread usage; This just causes overvoltage protection device running status such as lightning arrester and aging performance thereof to have no way of finding out about it, and serious threat is to the safe operation of electrical network.
The utility model content
The technical matters that the utility model will solve provides a kind of lightning arrester deterioration monitoring alarm, can monitor the running status of lightning arrester at any time, guarantees the safe operation of electrical network.
The technical scheme of the utility model is:
Lightning arrester deterioration monitoring alarm comprises alarm sensor that is connected in the arrester ground end and the lightning arrester on-line monitoring appearance that is connected with alarm sensor.
Described alarm sensor is connected on the ground connection copper bar.
Described alarm sensor is selected the balancing flux sensor for use.
The advantage of the utility model: the utility model passes alarm sensor ground connection with the earth terminal of lightning arrester; Obtain lightning arrester Leakage Current information uploading to lightning arrester on-line monitoring appearance by sensor; Monitor the operation conditions of lightning arrester in real time through monitor, guarantee the normal use of lightning arrester.
