This standard

20、 is a product (family) standard (according to EN 292-1) giving common requirements for the wind turbines mentioned in Clause 1 (Scope). The document contains a standard part and an informative annex. Annex A consists of national normative documents and/or regulations that specify either the present

21、safety requirements for personnel or give the national supplements to these minimum requirements at the time this standard was prepared (January 2000). The format of the standard is based, where possible, on a practical approach for manufacturers and designers who have to meet the requirements, auth

22、orities who have to check the design, owners who have legal responsibilities. For the determination of the hazards described in this standard EN 1050 should be applied. 5 EN 50308:2004 1 Scope This European Standard specifies requirements for protective measures relating to the health and safety of

23、personnel, relevant to commissioning, operation and maintenance of wind turbines. It does not describe instructions and provisions for safe working during manufacture, transport, assembly and installation of the wind turbine. Requirements are specified regarding hardware provisions being a part of t

24、he turbine such as platforms, ladders, lighting, manuals and warning signs to accommodate safe and quick operation, inspection and maintenance. The requirements and/or measures specified account for the hazards of mechanical origin such as falling, slipping, locking in, of thermal origin (fire) such

25、 as burns by flames or explosions, of electricity such as contact with live parts, generated by noise such as stress and loss of hearing, generated by neglecting ergonomic principles in machine design such as unhealthy postures or human errors. This standard is prepared for horizontal axis, grid con

26、nected wind turbines. For other concepts (e.g. vertical axis turbines) the principles are still valid, but the specific rules or requirements have to be adjusted to the actual concept. Additional provisions and procedures are necessary for turbines installed in water or offshore. The present documen

27、t only draws attention to these. Provisions and procedures for lifts and Suspended Access Equipment (SAE) in the turbine tower are not included in this standard. This standard is not applicable to wind turbines manufactured before the date of its publication by CENELEC. 2 Normative references The fo

39、quirements Wind turbines shall be designed according the principles of EN 292. The general principles to avoid risks to health and safety are laid down in Clause 5 of EN 292-1 (Strategy for selecting safety measures). The initial design of wind turbines must take account of how risks to the health a

40、nd safety of persons are to be minimised. Structural provisions include e.g. door-openings, access-openings, floors, platforms and railings, ladders with fall protection equipment, passages and working spaces, anchorage points and hand grips, lighting, guarding of moving parts, protection against el

41、ectrical hazards, sound barriers, noise isolation or thermal isolation. Some of these provisions have an effect on the structural integrity of the turbine e.g. door openings, doorstep height, access openings. The design shall include provisions for permanent safe access (ladders, platforms, anchorag

42、e points, lighting, etc.) to reach the locations for inspection and maintenance activities and to perform these activities safely. All items shall be safe during the turbine lifetime (providing that they are maintained according to the operators instruction manual and maintenance manual for the turb

43、ine). Accessible parts of the machinery shall have no sharp edges, no sharp angles and no rough surfaces likely to cause injury. Normal control of the wind turbine shall be possible without ascending to the turbine nacelle. Control panels shall be placed so that unintentional or erroneous operation

44、is prevented. If a wind turbine has more than one control panel/unit, it shall only be possible to operate it from one panel/unit at a time. Where remote operation of a wind turbine is possible (e.g. via a modem link) a local control switch shall be available to cut off the remote mode and all other

45、 control systems in the turbine with the exception of any emergency stop. It shall be possible to block, vent, release or isolate/disconnect any stored or trapped energy that can cause risk during maintenance where parts of the turbine are powered by an energy source other than wind, such as electri

46、cal energy inside a capacitor bank or battery, mechanical energy inside a spring loaded system or brake system, hydraulic energy inside pressurised accumulators, gravity. EN 982 shall be followed to release stored energy. EN 1037 shall be followed to prevent unexpected startup. 4.2 Passages Doors, h

47、atches, access and escape passages shall be in accordance with 6.0 of EN 292-2. Dimensions are based on EN 547-1 and EN 547-3. 4.2.1 Access All normal access points to wind turbines shall be equipped by the manufacturer with means to make the turbines inaccessible, so as to prevent unauthorised pers

48、ons from gaining access. In particular, access to the control panel, the machinery and electrical parts of the wind turbine by unauthorised persons shall be prevented. EN 50308:2004 8 Access ways, passages, doors and climbing provisions shall be designed with personnel safety in mind. They shall not

49、 to be obstructed by fixed auxiliary appliances, piping, wiring or by stored items. Doors being the entrance to the turbine and/or to rooms with electrical switch gear (having an escape function) shall have provision of unobstructed passage at least 0,6 m wide, which may have rounded off corners, no sharp edges likely to cause injury, a (additionally installed) horizontal part to step on of at least 0,3 m wide, a platform or floor inside and outside with a di
