Embodiment Construction

[0031] Combine below Figure 1-Figure 6 Specific embodiments of the present invention are described in detail:

[0032] The present invention includes a casing 1 , and a current transformer 11 and a fixed line card 12 are arranged on the upper end of the casing 1 . A control circuit unit (detection and judgment system) with a fault detection and judgment function is arranged inside the housing 1 , and components such as the control circuit unit and a battery are located in the cavity 13 at the upper end of the housing 1 . A fault indication unit is provided at the lower part of the housing 1 . The above-mentioned control circuit unit, current transformer 11 and fixed line card 12 are the same as those in the existing products, so they will not be repeated here. The point of improvement of the present invention over the prior art is the fault indication unit, in which a mechanical warning device is designed.

[0033] Described fault indicator unit comprises fault indicator l...

Abstract

The invention provides a line fault positioning and warning device comprising a shell, a control circuit unit and a fault indication unit. The fault indication unit consists of a fault indicator lamp, a mechanical warning device and a short message warning module; the mechanical warning device includes a transmitter body; hoodle holes are formed in the laterial peripheral direction of the lower half part of the transmitter body at equal intervals; and hoodles are arranged inside the hoodle holes. When a fault occurs, the transmitter body of the mechanical warning device pops up from the inside of the shell and hoodles at the lower half part of the transmitter body are release; and the hoodle can fall to a place at a distance of two meters from the shell and thus the transmitter body, the hoodle, and a warning rope form a series of strong warning marks that can be discovered easily even at weather with low visibility.

Description

technical field [0001] The invention relates to a line fault location warning device. Background technique [0002] my country's electric power industry has made great progress in recent years, and the country's economic development has also grown a lot. Power lines and power grids have also become more and more dense. Causes a higher failure rate of the line. The line fault warning (indicating) device is a fault indicating device installed on the line. The current line fault warning (indicating) devices all use a flop mechanism to indicate the fault state. When a fault occurs, the flop mechanism rotates and the red indicator Located at the position of the acrylic transparent plate, so that the staff can observe whether there is a fault. [0003] However, the flop agency has the following problems: [0004] 1. When the weather is cloudy or foggy and the air visibility is low, it is difficult to observe the red sign at the bottom of the line fault warning (indicator) device...
