Description

Quick Details Model Number: CBDL-JDG? Brand Name: Chaobo ?Joint Type: Pressure Spring Type ?Application: Overhead 6-35KV High Voltage Cable IP Code: IP65 ? Place of Origin: Zhejiang, China (Mainland) Lead time for sample: Within 5 days?■?Function and Benefit ◆Indicate 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 Parameters?◆Applicable voltage grade: U≥6-35KV ◆Applicable wire current: ?I≤1200A ◆Applicable wire diameter: 16mm sq≤D≤240mm sq ◆Action response time: 0.06s≤t≤3s ◆Reset time: 6,12,24,48H (Selectable, Default 24H) ◆Ambient temperature: -35℃≤T≤+70℃ ◆Operation times: ≥5000Times ◆Static power loss: ≤10μW ◆Protection class:?IP65■?Action principle Short circuit detection principle:?According to the phenomenon of short circuit,the current break when ?short 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 still show 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 D happen grounding fault.?Products Type: ??Test Report: Our products have already passed the test by CMA, CNAS,CE till now, and we also have ability to arrange other relevant testing and factory audit as yo
