变电配电系统Switchgear (HICLAD-10ZA)
High performance air insulated switchgear designed and manufactured in accordance with IEC 62271.
Product Features
Switchgear combined electrical devices, which are protection relays and power meter, and isolate electrical equipment in power systems.
Ensures safety of electrical disturbution and efficient disturbution of electricity.
- Complete switchgear panel designed and manufactured in a Meidensha Group factory.
- Fully type tested in accordance with IEC 62771 in STL certified laboratory.
- Withdrawable VCB for ease of operation and maintenance with LSC2B Loss of Service Continuity (i.e. no need to shut down switchboard when servicing the VCB).
- Withdrawable VT (Isolate the VT during power energization to fulfil Power Utilities requirement.)
- Ample cable termination space to accept all types of power utilities incoming cables.
- Vacuum bottles manufactured by Meidensha Japan to ensure high reliability and high arc quenching performance on all types of loads.
Applications / Solutions
- For Power Distribution in a city.
- Ring or radial feed configuration. Details specification as per utility company’s requirements.
- For a big commercial complex, data center or infrastructure projects.
- On the receiving side of incoming power supply from utility company.
Panel features together with the relevant protection and metering scheme must comply with power utility company’s interfacing requirement. - Ring or cascaded feed configuration for distribution of power within the building.
Objective is to provide flexibility as well as security of the power supply over a large area.
Mechanical interlocks should be provided between 2 changeover circuit breakers.
Pad-locks should be provided for the Circuit Breaker truck and the Earthing Switch to ensure operational safety. - As a switching and protection device for large HV motors in the form of Direct on Line or Auto Transformer Starter.
Capable to work in conjunction with HV Frequency Inverters.
- On the receiving side of incoming power supply from utility company.
