Embodiment 1

[0014] refer to figure 1 , this embodiment 1 is composed of the head end unit installed in the electric room or station substation, the intermediate unit installed on the power line that needs to be positioned in sections, and the end unit installed on the power line of the electrical equipment control device or encapsulated in the circuit breaker unit composition. The head-end unit includes a data processing single-chip microcomputer 4 , a first carrier communication module 6 connected to the data processing single-chip microcomputer 4 , a voice alarm module 1 , a communication interface 2 and a power supply 3 . The intermediate unit 12 is the carrier communication module 1 segment 9 and the dedicated carrier communication module n segment 10, n segments of the carrier communication module n can be set as required, the carrier communication module 1 segment 9 and the carrier communication module n segment 10 and Another data processing MCU connection. The terminal unit has ...

Embodiment 2

[0016] refer to image 3 , Embodiment 2 has the same structure as Embodiment 1, except that the intermediate unit 12 is a capacitance detection module 7, and the capacitance detection module 7 connected to the power line is connected with the data processing single-chip microcomputer 4. The capacitance detection module detects the capacitance between lines or the ground capacitance. After the data processing single-chip computer calculates and processes according to the pre-stored data and the detection data provided by the capacitance detection module, it obtains the location information of the disconnection distance and outputs it to the alarm module at the same time.

Abstract

The invention discloses a breakage alarming device of electric power wire, which is composed of head unit (11) in the electric chamber or table various part, middle unit (12) on the segmented locating electric wire and terminal unit (13) on the electric wire of electric equipment control device or in the circuit breaker, wherein the head unit (11) contains data disposing single-chip set (4), the first carrier communication mode (6) in connection with the data disposing single-chip set (4), voice alarming mode (1), communication interface (2) and feeding power (3); the terminal unit contains second carrier communication mode (8) in connection with the data disposal single-chip set. The invention can find breakage fault in time and provides the location information of breakage point, which develops condition for finding and disposing fault in time.

Description

technical field [0001] The invention relates to a device for online fault detection of a power supply line, which belongs to a power line disconnection alarm device. Background technique [0002] The main problems of the existing products: it cannot work when there is a power failure; there is no positioning function for the location of the broken line, and for the occasions with long lines or complex terrain, the staff cannot send personnel to the scene to deal with them in time, especially if the line is cut by human beings In such a situation, if you cannot quickly locate the location, it will be difficult to better protect the safety of the power supply line. Invention content: [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned technologies, and provide a power line disconnection alarm device that can detect disconnection faults in time and provide location information of disconnection points at the same time. [0004]...
