The utility model discloses unite two into one fault indicator and electrified display, reduce the volume of device, when normal, give rechargeable battery or the incessant charging of condenser through rectification step-down module, guarantee fault indicator normal operating voltage, during the circuit trouble, electrified display does not have the voltage this moment, provides necessary operating voltage for fault indicator by rechargeable battery or condenser.

Description

Fault indicator
Technical Field
The utility model relates to a cable type line safety equipment field especially relates to panel fault indicator technique.
Background
In order to conveniently find faults, at present, in a distribution network, cable type lines all use grounding short circuit panel type fault indicators with batteries, the batteries have the main functions of providing detection and fault alarm power supplies for the fault indicators, but the fault indicators cannot work normally basically for 2 years due to the limited service life of the batteries and the influence of outdoor moisture. For this reason, it is currently necessary to spend a large amount of manpower and material resources to replace the fault indicator battery. Greatly influencing the working efficiency.
Disclosure of Invention
The utility model aims to solve the technical problem that realize a panel mounted self-power fault indicator who shows with electricity.
In order to realize the purpose, the utility model discloses a technical scheme be: the utility model provides a fault indicator, the signal input part of indicator host computer passes through the sensing device of transmission fiber connection card on the cable, be equipped with the battery that provides the electric energy in the indicator host computer, be equipped with the fault indication lamp on the indicator casing, install voltage sensor on the high-voltage terminal of one time, voltage sensor passes through the wire with the alternating current that the response was gone out and carries to rectification step-down module, the power output end of rectification step-down module is connected through the wire and is connected the battery and charge for the battery.
The battery is a rechargeable battery or a capacitor.
The indicator host is provided with an electrified indicating lamp, and the electrified indicating lamp is connected with a wire between the voltage sensor and the rectification voltage reduction module through a signal wire.
The fault indicator is installed on the ring main unit.
The utility model discloses unite two into one fault indicator and electrified display, reduce the volume of device, when normal, give rechargeable battery or the incessant charging of condenser through rectification step-down module, guarantee fault indicator normal operating voltage, during the circuit trouble, electrified display does not have the voltage this moment, provides necessary operating voltage for fault indicator by rechargeable battery or condenser.
Drawings
The following brief descriptions of the contents expressed by each figure and the marks in the figures in the specification of the present invention are as follows:
FIG. 1 is a schematic view of a fault indicator configuration;
the labels in the above figures are: 1. an induction device; 2. a transmission optical fiber; 3. a battery; 4. an indicator host; 5. a fault indicator light; 6. a live indicator light; 7. a rectification voltage reduction module; 8. a primary high voltage terminal; 9. a voltage sensor.
Detailed Description
The following description of the embodiments with reference to the drawings is intended to illustrate the present invention in further detail, such as the shapes and structures of the components, the mutual positions and connections between the components, the functions and working principles of the components, the manufacturing process, and the operation and use methods, etc., so as to help those skilled in the art understand the present invention more completely, accurately and deeply.
The signal input end of an indicator host 4 of the fault indicator is connected with an induction device 1 clamped on a cable through a transmission optical fiber 2, a battery 3 for providing electric energy is arranged in the indicator host 4, the battery 3 is a rechargeable battery or a capacitor, and a fault indicator lamp 5 is arranged on an indicator shell, so that a traditional fault indicator structure is formed.
Install voltage sensor 9 on the primary high voltage terminal 8, voltage sensor 9 carries the alternating current that the induction was come out to rectification step-down module 7 through the wire, and the power output end of rectification step-down module 7 is connected and is passed through wire connection battery 3 and charge for battery 3. The voltage sensor 9 can adopt the voltage sensor 9 of an induction type electrified display widely used in a distribution network cable line, the electrified display device is composed of the voltage sensor 9, the indicator host machine 4 and the like, certain relative ground alternating voltage is induced on the indicator through the voltage sensor 9, the voltage charges the battery 3 on the fault indicator through the rectification voltage-reducing module 7, and frequent replacement of the battery 3 is avoided.
Fault indicator installs on the looped netowrk cabinet, can reduce the operating panel trompil on the interval, reduces trompil cost and trompil area, is equipped with electrified pilot lamp 6 on the indicator host computer 4, whether electrified pilot lamp 6 passes through the wire between signal line connection voltage sensor 9 and the rectification step-down module 7, can show that supply circuit has the trouble, through addding self-power supply mechanism, makes fault indicator electric current can long-time operation, avoids often changing battery 3, very big improvement work efficiency.
The present invention has been described above with reference to the accompanying drawings, and it is to be understood that the invention is not limited to the specific embodiments described above, and that the invention is not limited to the specific embodiments described above, but rather is intended to cover various insubstantial modifications of the inventive method and solution, or its application to other applications without modification.
