Product Functions
◆Provides accurate 100V voltage measurement for monitoring and protection circuits.
◆Supplies 220V operating power directly to switchgear mechanisms .
◆Offers reliable insulation and electrical protection through its epoxy resin construction and integrated fuse.
◆Facilitates easy integration into ring main unit (RMU) and switch cabinet designs.
Applicable Environment
◇Designed for indoor use in medium-voltage switchgear, specifically in ring network cabinets (ring main units).
◇Suitable for switch cabinets and compact secondary distribution systems requiring combined measurement and power supply.
◇Operates effectively in environments where space-saving and reliable dual-function components are required.
Product Highlights
◆Dual-Function Design: Combines voltage measurement (100V) and power supply (220V) in a single, compact unit.
◆Enhanced Protection: Features a fuse-protected primary winding for increased safety and durability.
◆Plug-In Convenience: Simplifies installation and maintenance with its ready-to-use plug-type design.
◆Robust Construction: Made with high-quality epoxy resin for excellent insulation and long-term reliability in switchgear environments.
◆Customizable: Can be tailored to meet specific technical or dimensional requirements through direct manufacturer consultation.
Installation Instructions
◇Ensure the ring network cabinet or switchgear panel is de-energized before installation.
◇Verify that the sensor’s voltage ratings (100V measurement / 220V power supply) match the system requirements.
◇Insert the sensor into the designated plug-in compartment within the cabinet, ensuring a secure and proper connection.
◇Connect the secondary wiring according to the provided diagram typically linking measurement outputs to monitoring devices and the 220V supply to the operating mechanism.
◇For any non-standard application or special requirements, discuss details with the manufacturer prior to ordering.
