Detailed Description

Overhead Line Short Circuit And Earth Fault Indicator ( SNV-308 )

 

Specifications

SNV fault indicators can quickly and easily indicate fault and identify fault locations, used in cable and overhead power lines.

 

Characteristic

The shell using high strength and high transparency aeronautical material Fully Fashioned, and treated withnanotechnology, better perspectivity. resist filth, anti-aging, without maintenance, long service life. Built-in high performance lithium battery, Service life can reach more than eight years. The circuit board using special chip and MCU etc imported Components. The shell made from aeronautical material and nano materials. The clamp with nickel plating process, best magnetic conductivity, Install and Remove with Electricity. Fault indication turn card brush with red fluorescent paint,strong visual,it can clear instructions with lightin the night, and the color not fade under sun ultraviolet light for a long time.

 

Function and BenefitIndicate the fault line and fault point quickly, lessen the blackout area;Shorten troubleshooting time,improving electricity and power supply reliability;Accurately indicate the instant fault, which is conducive to rule out the power supply problems;Providing technical means for find the hidden permanent fault point;Shorten the search time to find the fault point, reduce the labor intensity of line patrol person;Defining the responsibility of the fault area and responsible people;Avoiding traditional multiple switch out,switch on,line patrol to the effects of power equipment.

 

Technical ParametersApplicable voltage grade: U≥6-35KVApplicable wire current: I≤1200AApplicable wire diameter: 16mm sq≤D≤240mm sqAction response time: 0.06s≤t≤3sReset time: 6,12,24,48H (Selectable, Default 24H)Ambient temperature: -35℃≤T≤+70℃Operation times: ≥5000TimesStatic power loss: ≤10μW

Action principleShort circuit detection principle: According to the phenomenon of short circuit,the current break whenshort circuit happen, the action on the basis of the protection movement power outages.Used to judge the short circuit fault indicator diagram:

As line 2# B phase 2,5,8 indicator and line 2# C phase 3,6,9 indicator turn red, but the 11,12 indicator stillshow white, that judged the point D happen short circuit

 

Used to judge the grounding fault indicator diagram:

As line 2# C phase 3,6,9 indicator turn red,but the 12 indicator still show white, that judged the point Dhappen grounding fault.

The experimental technical requirements:In normal line steady current running after more than 20 seconds then mutation 1 second current back tozero that the indicator show alarm indication.Indicator alarm reset in a steady line current is greater than 20A,it will automatic reset within 20 seconds;When the line current is less than 20A, the indicator will automatic reset within 48H.Running time: ≥20S               The action response time: ≤1SMutation current: ≥150A         Reset time: 6,12,24,48H (Selectable, Default 24H)Automatic reset current and response time: ≥20A,20S
