Abstract
The utility model relates to a cable fault indicator connected with an external power source, comprising a super capacitor, a DC rectifier module, a display panel and a sensor. The super capacitor is a 48V DC power supply and the 48V voltage is converted to 5V working voltage of the display panel through the DC rectifier module. The display panel can determine fault positions according to the varying rule of the current and the voltage on the faulted cables and the varying pattern is sensed by the sensor connected to the display panel by optical fibers. The fault indicator is a novel fault indicator powered by a super capacitor module. The cable fault indicator connected with an external power source employs a 48V DC power supply of the super capacitor module within a distribution automation station. The voltage is converted to working voltage of the fault indicator through the DC/DC rectifier module and is provided to the fault indicator through a protection circuit. A battery is not needed to be replaced to guarantee normal operation of the fault indicator.
Description
Technical field
The utility model belongs to power distribution automation technical field, is related to the on-line monitoring of the identification of electrical equipment fault high reliability and power equipment hidden danger, especially a kind of external power supply type cable fault indicator.
Background technology
Fault detector is used very extensive as a kind of important tool of searching trouble spot on the power circuit in power industry.Fault detector provides great convenience by detecting outlet, branch and the section at distribution line failure electric current indication fault place to trouble-shooting.Though developed country's power distribution automation level is very high, the main mode of searching distribution line failure still relies on fault detector.
The working power of traditional fault detector has dual mode: first kind is to use lithium battery that power supply is provided, battery electric quantity can use 3-4 usually, surpass that battery can take place not work tenure of use or situation such as fault misdescription, operation to the intelligent power distribution net brings influence, and controller switching equipment quantity is ten hundreds of, very huge, changing battery is again the thing of a time and effort consuming.Second kind is the current draw working power of utilizing a circuit of electrical network, and this kind working power needs electric current on the circuit can not be less than its minimum working current, but just can not use on the less circuit of some little circuit branches and load.
The utility model content
The purpose of this utility model is to overcome the weak point of original technology, and a kind of external power supply type cable fault indicator is provided, and to solve the defective of traditional fault detector working power, provides working power by super-capacitor module.
The technical scheme that the utility model technical solution problem adopts is:
A kind of external power supply type cable fault indicator, it is characterized in that: comprise super capacitor, direct current rectification module, display panel and sensor, super capacitor is the 48V direct supply, through the direct current rectification module, voltage is adjusted into the operating voltage 5V of display panel, and the electric current when the sensor senses cable that display panel connects by optical fiber breaks down on the cable and the Changing Pattern of voltage are with the failure judgement position.
And, a protection module also is installed on the circuit between direct current rectification module and the display panel.
Advantage of the present utility model and good effect are:
1, this indicator is a kind of panel type accident indicator that is applied on the cable, electric current when this fault detector breaks down according to cable on the cable and the Changing Pattern of voltage, the failure judgement position, can not cause fault detector normally not use less than its minimum working current because of the electric current on circuit, guarantee the good operation of fault detector, be mainly used in the power distribution automation field in the intelligent grid field.
2, this fault detector is a kind of new-type fault detector that working power is provided by super-capacitor module; adopt the 48V direct supply of super-capacitor module in the power distribution automation station; through DC/DC direct current rectification module; voltage is adjusted into the operating voltage of fault detector; offer fault detector through holding circuit again; can change battery, guarantee the good operation of fault detector.
Description of drawings
Fig. 1 is structure connection diagram of the present utility model.
Embodiment:
For further understanding content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows.Need to prove that present embodiment is descriptive, is not determinate, can not limit protection domain of the present utility model thus.
A kind of external power supply type cable fault indicator; comprise super capacitor, direct current rectification module, protection module, display panel and sensor; super capacitor is the 48V direct supply; through DC/DC direct current rectification module; voltage is adjusted into the operating voltage 5V of display panel; offer display panel, the electric current when the sensor senses cable that display panel connects by optical fiber breaks down on the cable and the Changing Pattern of voltage, failure judgement position through holding circuit again.
This indicator can not cause fault detector normally not use less than its minimum working current because of the electric current on circuit, guarantees the good operation of fault detector.
Described each circuit block of present embodiment is prior art.
