Introduction

This publication contains the information necessary for instal-lation and putting into service of HD4 medium voltage circuit-breakers.For correct usage of the product, please read this manualcarefully.For correct mounting of accessories and/or spare parts pleaserefer to the relevant instructions.Like all the apparatus manufactured by us, the HD4 circuit-breakers are designed for different installation configurations.They do, however, allow further technical-constructional vari-ations (at the customer’s request) to suit special installationrequirements.For this reason, the information given below does not alwayscover special configurations.

Apart from this booklet, it is therefore always necessary to referto the latest technical documentation available (circuit dia-gram, wiring diagrams, assembly and installation drawings,any studies of protection co-ordination, etc.), especially withregard to any variations from standardized configurationsrequested.

All the operations regarding installation, puttinginto service, operation and maintenance must becarried out by suitably qualified personnel with in-depth knowledge of the apparatus.

Only use original spare parts for maintenance operations.For further information, also see the technical catalogue of thecircuit-breaker and the spare parts catalogue.

Programme for the environmental protection

The HD4 circuit-breakers comply with ISO 14000 Standards(Guidelines for the Environmental Management).The production system of the Medium Voltage factories com-plies for the environmental protection in terms of energyconsumption, raw materials and waste.The environmental impact of the product life cycle is assessedby the LCA - Life Cycle Assessment procedure, which is alsothe result of a well-focused project phase in the selection ofmaterials, processes and packaging.Production techniques are carried out in order to achieve aneasy dismantling and separation of the components at the endof the circuit-breaker life cycle, while optimizing the recyclingprocess.

11. Indications for handlingapparatus with SF6

SF6 in its pure state is an odourless, colourless, non-toxic gaswith a density about six times higher than air.For this reason, although it does not have any specific physi-ological effects, it can produce the effects caused by lack ofoxygen in ambients saturated with SF6.During the interruption phase of the circuit-breaker, an electricarc is produced which decomposes a very small amount ofSF6. The decomposition products remain inside the poles andare absorbed by special substances which act as molecularsieves.The probability of contact with decomposed SF6 is extremelyremote, and its presence in small quantities (1-3 ppm) isimmediately noticeable because of its sour and unpleasantsmell.

SF6 este un gaz pur, fara miros, fara culoare, netoxic, cu odensitate de sase ori mai mare decat cea a aerului.Din acest motiv, desi acesta nu are nici un efect psihologic,poate cauza lispa oxigenului intr-un mediu bocat de SF6.In timpul procesului de intrerupere, arcul electric produce descompunerea unei mici cantitati de SF6.Produsele rezultate in urma descompunerii raman in interiorul polului si sunt absorbite de o substanta speciala care actioneaza ca osita moleculara.Probabilitatea de a intra in contact cu SF6 descompus este foartemica, si prezenta in cantitati foarte mici (1-3 ppm) este imediat observata deoarece miroase neplacut si are un gust acru.In acest caz camera trebuie aerisita inainte ca orice persoanasa intre acolo.

12. Piese de rezerva si accesorii

Toate operatiile de inlcocuire a anumitor suban-sable sau accesorii ale intrerupatoarelor trebuie de catre personal cu calificare ridicata in domeniulechipamentelor si instalatiilor electrice. Inainte de realizarea oricarei operatii trebuie verificat ca intre-rupatorul este in pozitia deschis, arcul dezarmat sise verifica lipsa tensiunii (medie tensiune si ten-siunea de alimentare auxiliara).

12. Spare parts and accessories

All assembly operations of spare parts/accessoriesregarding installation, putting into service, serviceand maintenance must be carried out by ABB per-sonnel or suitably qualified customer personnel within-depth knowledge of the apparatus (IEC 60694, CEIEN 60694 para. 10.4.2.). Should the maintenance bycarried out by the customer’s personnel, responsi-bility for any interventions lies with the customer.Before carrying out any operation, check that thecircuit-breaker is open, the springs discharged andthat there is no voltage (medium voltage circuit andauxiliary circuits).
