The series brings to the market a versatile switchgear ready to cover a variety of installation requirements and market segments. Each switchboard is composed of a busbar compartment and cable compartment, both air insulated and separated by a 3 position gas insulated switch disconnector. The modularity and compact dimensions of the product allow for a reduced footprint and ease of installation where space is limited. A low voltage control box can be included to contain the low voltage circuits as well as protection and measuring devices. Applications for the ECOSMART MIX series include: • Public medium voltage secondary distribution • Transformers substations • Hospitals • Residential centers • Power transformer protection • Data center protection • Industries • Renewable energy plants ECOSMART MIX List of available functional units ECOSMART MIX 12-24kV TYPOLOGIES DESCRIPTION L Cables riser B Busbar riser (Incoming) BV Busbar riser (Incoming) with VT arrangement BE Busbar riser with earth switch BAV Busbar riser with CT and VT arrangement S Switch disconnector SA Switch disconnector and CT arrangement SAV Switch disconnector and CT/VT arrangement SB-L Switch disconnector and busbar riser left SB-R Switch disconnector and busbar riser right SBM-L Switch disconnector busbar riser left with CT/VT arrangement SBM-R Switch disconnector busbar riser right and CT/VT arrangement FS Switch disconnector and fuses FSL Switch disconnector, fuses, lateral cables outgoing MFS Measure switch disconnector with fuses and VT arrangement CBS Vacuum circuit breaker and disconnector 2 ECOSMART MIX 12-24kV TYPOLOGIES DESCRIPTION CBSB Vacuum circuit breaker, disconnector, busbar riser CBSA Vacuum circuit breaker, disconnector, CT arrangement CBSV Vacuum circuit breaker, disconnector, VT arrangement CBSAV Vacuum circuit breaker, disconnector, CT & VT arrangement CBSAB Vacuum circuit breaker, disconnector, CT arrangement, busbar riser CB2SA Vacuum circuit breaker, double disconnector, CT arrangement CBS-CV Vacuum circuit breaker, Disconnector, CT/VT arrangement (up-side down version) VG Integrated system with vacuum circuit breaker and gas insulated switch disconnector VG-A Integrated system with vacuum circuit breaker; gas insulated switch disconnector with CT VG-AV Integrated system with vacuum circuit breaker; gas insulated switch disconnector with CT/VT VG-AB Integrated system with vacuum circuit breaker; gas insulated switch disconnector with CT, busbar riser Integrated system with vacuum circuit breaker; gas insulated switch disconnector with CT/VT VG-AVB busbar riser MAV Metering with CT/VT, incoming and outgoing from busbar compartment MFAV Metering with CT/VT protected by fuses arrangement, incoming and outgoing from busbar compartment MAVL Metering with CT/VT, incoming from cables compartment and outgoing from busbar compartment MAVD Metering with CT VT, incoming and outgoing from cables compartment Example of functional unit S: Structure and components 1.

It’s composed of a vacuum circuit breaker combined with a three position disconnector, embedded in the same welded stainless steel tank filled with insulated gas. All the operations are performed from the front of the equipment. The vacuum circuit breaker, located upstream the disconnector, is equipped with an operating mechanism, spring stored energy type, with opening and closing operations independent from the operator. The operating mechanism spring can be charged manually, through the lever embedded on the apparatus front, or by the gear motor supplied upon request. Opening and closing operations are carried out with the available push buttons or by means of the opening and closing coils, actuated from remote. The disconnector, connected downstream of the circuit breaker, is a three position type (closed-sectionalised- earthed) and is provided with an operating mechanism exceeding dead center type, having opening and closing speed independent from the operator. The three upper insulators of the apparatus connect the circuit breaker’s contacts to the main busbars system by means of bolts, while the lower insulators allow the connection between the disconnector and the medium voltage cables. The insulators are made of quartz-reinforced epoxy resin. 1700mm 1700mm 750mm 500mm Busbars Compartment The bus bar compartment contains the three phase busbar system to allow the extension with other units on both sides while remaining separated from the other compartments. The busbars are made of copper size 30x8mm, for rated currents up to 630A (upon request the busbars system can be sized for rated current up to 800A or 1250A). The busbars are connected to the switch-disconnectors upper contacts. Switch Disconnector

  • Ground Lead Disconnectors on Distribution-Class Surge Arresters
    01.4TB.017 Ground Lead Disconnectors on Distribution-Class Surge Arresters July 18, 1991 Many current models of zinc oxide distribution or riser pole arresters come equipped with ground lead disconnectors. This is a device which is mounted on the ground end of the arrester and which looks about like a small hockey puck. The enclosure is black, blue or green plastic, a couple of inches in diameter and an inch or so tall. The normal failure mode of these arresters is a short circuit to ground, causing ground fault current to flow. This current will cause the arrester body to fail if it is not stopped quickly. The first function of the ground lead disconnector is to disconnect the ground lead of the surge arrester in case of an internal failure of the arrester, preventing explosive failure of the arrester body. The ground lead disconnector contains a cartridge in series with a gap. The gap is shunted by a resistor. As the current rises, the voltage across the gap increases until the gap flashes over, creating an arc which ignites the cartridge, blowing the ground lead free. The ground lead disconnector is not a fault current interrupter. The arc drawn by the ground lead as it separates from the body of the arrester may or may not go out on its own. If it does not go out, a circuit breaker, recloser or fuse must operate to extinguish the arc. The ground lead disconnector is expected to create a gap which will not reignite when power is reapplied to the circuit, but the gap which will be created is a function of the length and flexibility of the ground lead.

  • Consultation on the Implementation of Engineering Recommendation Er G77
    CONSULTATION ON THE IMPLEMENTATION OF ENGINEERING RECOMMENDATION ER G77 VOLUME I: SUMMARY REPORT ETSU S/P2/00356/REP/1 DTI/Pub URN 02/809 Contractor Halcrow Group Ltd Subcontractors SunDog Energy Ltd EA Technology Ltd I-Power Ltd Prepared by J Thornycroft M Cotterell A Collinson The work described in this report was carried out under contract as part of the DTI Sustainable Energy Programmes. The views and judgements expressed in this report are those of the contractor and do not necessarily reflect those of the DTI. First published 2002 © Crown copyright 2002 EXECUTIVE SUMMARY This report presents the results of continued consultation within the Electricity Industry and PV Industry leading to the publication of Engineering Recommendation ER G77/1: ‘Connection of Single-phase Inverter Connected Photovoltaic (PV) Generating Equipment of up to 5kVA in Parallel with a Distribution Network Operators (DNOs) Distribution System ’. It also incorporates a specific piece of technical work carried out under a Subproject ETSU/S/P2/00400. The final subgroup report on that work is reproduced in Volume II. OBJECTIVES This project continues the objectives of a previous ETSU project ETSU/S/P2/00215 that set-up the ‘ER G77 Working Group’ as part of the initiative to: • Continue consultation with the DNOs principally through the ER G77 Group • Continue consultation in the PV Industry through PV-UK membership • Monitor and include experience from the implementation of ER G77 • Act as a forum for discussion of issues arising and recommended improvements to ER G77 • Provide a source of expertise and consultation on PV electrical matters for projects such as the DTI supported Domestic Field Trial • Provide a link to BSI Standards Work in the field • Define and provide a link to Subprojects investigating specific technical questions related to ER G77 The aim has been to help develop the final version of ER G77/1 that is acceptable to the PV industry and electricity supply industry.
