Indoor Load break switch, normally used for RMU. Ring main unit is used in a secondary distributionsystem. lt is basically used for an uninterrupted power supply. Alongside, it also protects yoursecondary side transformer from the occasional transient currents.
Use environmental conditions
1. Altitude: no more than 2,500 meters; plateau type 4.000 meters;
2.Ambient temperature:-30°C-+40°C(special requirements -40C-+40C)
3. Relative humidity: daily average not greater than 95%, monthly average not greater than 90% (25C)
4. wind sped:no morethan 35m's; poution leve is level ;the creepage distance ofthe porcelain sleve is 1050mm 1320mm the nominal creepage distance is not es than25mm/kV);
5.Sunshine: 0.1w/cm?;
6.lce coating: 10mm(MAX);
7. Earthguake conditions: verical acceleration 0.30; horizontal acceleration 0.15g max in place without fammable substances,explosion hazards, chemical corosion andsevere vibrations
Features:
1.Auto-locking phase-to-phase short-circuit fault: When the same short-circuit fault occurs on the user's branch line, the demarcation switch isopened and locked immediately after the substation breaker or recloser protection trips. After the substation recloses, other branch users on thefeeder quickly recover power supply
2.Quickly locate the faut point: After the user branch line accident causes the demarcation switch protection action,the responsible user willcutof the power. and it willrepot the accident information on its own iniiative.The power company dispatches personnelto check the cause oftheaccident through the handheld computer or communication module on the spot
3.The single-phase ground fault is automaticaly cut of: When a single-phase eath fault occurs on the user's branch ine,the demarcation switch isautomatically opened, The substation and other branch users on the feeder do not feel the fault
4.This switch can achieve the folowing functions: uick-break protection, over-current protection,three reclosing, event logging surge protectionzero sequence protection, realtime clock, post-acceleration acceleration, real-time status query, smart handheld control local/remote setting
