Embodiment Construction

[0007] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0008] refer to figure 1 According to the invention, the invention provides a method for prompting the electric leakage at the place where the water accumulates in the cable. It is characterized in that: a sound and light alarm is embedded in the side of the sign post of the cable joint, and the alarm is covered in the sign post by a transparent and waterproof hard plastic cover, and a reflector is installed on the inner side of the embedded alarm of the sign post; The alarm is connected in series with a large resistance resistor, and the two wire terminals are respectively buried in the ground on both sides of the sign pile. Among them, the transparent and waterproof hard plastic cover is transparent and has a certain effect of strengthening and scattering light, and will not hinder the transmission of sound. The two connecting wires of the sound and light alarm ar...

Abstract

The invention discloses a cable water accumulation part electric leakage prompting method. The method mainly comprises steps of embedding an audible and visual alarm in the side surface of a marker peg of a cable connector, covering the alarm into the marker peg through a transparent waterproof rigid plastic cover, and assembling a reflective mirror at the inner side of the embedded alarm of the marker peg; and connecting the audible and visual alarm with a resistor with a large resistance in series, and respectively burying two lead connectors into the ground on the two sides of the marker peg, wherein the transparent waterproof rigid plastic cover is transparent and has proper light strengthening and scattering functions, cannot influence the acoustic propagation, and the two leads of the audible and visual alarm, which are connected with the connectors, are respectively pulled underground along the two sides of the marker peg. When water is accumulated at the cable connector and causes electric leakage, the accumulated water is electrified, the two leads which are buried underground and the electrified accumulated water form a closed circuit loop, the power supply of the audible and visual alarm is turned on to audibly and visually alarm, and accordingly, pedestrians are alarmed to pay attention to the electric leakage cable.

Description

technical field [0001] The invention relates to the safety technology of electric cable distribution, in particular, it is a method for prompting electric leakage at the water accumulation place of the electric cable. technical background [0002] With the development of urban modernization, the overhead lines of street lamps are gradually converted to buried cable lines, and the technical requirements for cable laying have new specifications. The general buried cable lines are divided into underground direct buried cable boxes, cables laid in trenches, and cable signs are erected at places where underground cables are laid. The embedment position of the general sign piles (cards) is stipulated as follows: one piece of cable sign piles (cards) is buried at 20 meters in the straight section of the cable channel; one cable sign pile should be buried at each corner of the buried cable according to the corresponding symbol; each joint in the middle of the cable is A cable sign ...
