Product Description

 

Product Description

 

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.

Product Parameters

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)

Application Areas

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

Please note:
1. Main circuit scheme number and purpose.
2. Drawings: single-line system, arrangement, distribution room layout, auxiliary circuit wiring principle, terminal arrangement.
3. Components: model, specification, quantity.
4. Requirements for switchgear control, measurement and protection functions and other requirements for locking and automatic devices.
5. If a busbar bridge is required between switchgear or incoming line cabinets, the rated current carrying capacity of the busbar bridge, the span of the busbar bridge, the height from the ground and other specific requirements should be provided.
6. When accessories and spare parts are required, the type and quantity should be specified.
7. The switchgear is used in special environmental conditions, and other special requirements should be detailed when ordering.
