Whistling type fault indicator for 10kV line

Abstract

The invention discloses a whistling type fault indicator for a 10kV line. The whistling type fault indicator for the 10kV line comprises a foundation, a clamping device, a monitoring device and an alarm device, wherein the foundation is fixed with a casing, the casing is internally fixed with the monitoring device and the alarm device, the foundation is connected with the clamping device, and the clamping device is fixed below the foundation through a screw. The whistling type fault indicator is advantaged in that a fault line and a fault point can be accurately determined, properties of stable performance, high precision, strong anti-interference capability, attractive appearance and convenient mounting are realized, the whistling type fault indicator is rapid to start, and start can be realized within 0.1 second; service life is long, and a motor can be switched on and off for more than 100000 times without damage; automatic reset can be realized; after power supply of the line recovers, the fault indicator can reset automatically, the reset time is short, and automatic reset can be realized within 0.1 second; live-line loading and unloading can be realized; live-line loading and unloading are quite simple, and line operation is not influenced; technical means is provided for searching hidden fault points; the fault line and the fault point can be rapidly determined, and the fault elimination time is shortened.

Description

technical field [0001] The invention relates to a whistle-type fault indicator for 10kV lines, which is suitable for quickly and conveniently finding the fault location when the 10kV line is short-circuited or grounded. Specifically, it relates to a whistle-type line fault indicator when a fault occurs on a power transmission line, and belongs to the field of electric power construction auxiliary equipment. Background technique [0002] At present, the line fault indicator installed on the 10kV line is a flashing fault indicator. When the 10kV line is short-circuited or grounded, the fault indicator judges whether the A, B, and C phases on the line are faulty according to the magnitude of the current. When the current exceeds the set value, the indicator light of the line fault indicator turns red and flashes, and the power supply personnel judge the fault location according to the light of the fault indicator.

Problems solved by technology

[0003] With the development of social economy, the national electricity load continues to grow, especially in the distribution network system, there are more and more line branches, the operation is complicated, and the line short circuit or grounding occurs from time to time. After a fault occurs, the existing The indicator light of the line fault indicator will turn red and flash, and it is easy to check at night, but it is not easy to find the fault point due to light problems during the day, which brings great difficulties to the maintenance work, especially in remote areas, it is time-consuming and laborious to search, which affects The reliability of power supply brings great losses to the production and domestic electricity consumption of enterprises
