1.2.2. Principles of safety integration
(a) Machinery must be so constructed that it is fitted for its function, and can be adjusted and maintained without putting persons at risk when these operations are carried out under the conditions foreseen by the manufacturer.
The aim of measures taken must be to eliminate any risk of accident throughout the foreseeable lifetime of the machinery, including the phases of assembly and dismantling, even where risks of accident arise from foreseeable abnormal situations.
(b) In selecting the most appropriate methods, the manufacturer must apply the following principles, in the order given:
— eliminate or reduce risks as far as possible (inherently safe machinery design and construction),
— take the necessary protection measures in relation to risks that cannot be eliminated,
— inform users of the residual risks due to any shortcomings of the protection measures adopted, indicate whether any particular training is required and specify any need to provide personal protection equipment.
(c) When designing and constructing machinery, and when drafting the instructions, the manufacturer must envisage not only the normal use of the machinery but also uses which could reasonably be expected.
The machinery must be designed to prevent abnormal use if such use would engender a risk.In other cases the instructions must draw the user’s attention to ways — which experience has shown might occur — in which the machinery should not be used.
(d) Under the intended conditions of use, the discomfort, fatigue and psychological stress faced by the operator must be reduced to the minimum possible taking ergonomic principles into account.
(e) When designing and constructing machinery, the manufacturer must take account of the constraints to which the operator is subject as a result of the necessary or foreseeable use of personal protection equipment (such as footwear, gloves, etc.).
(f) Machinery must be supplied with all the essential special equipment and accessories to enable it to be adjusted, maintained and used without risk.
[DIRECTIVE 98/37/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL]
1.1.2. Принципы комплексной безопасности.
(a) Машинное оборудование должно конструироваться так, чтобы оно выполняло заранее предусмотренные функции, и чтобы была возможность производить их наладку и техническое обслуживание, не подвергая персонал риску во время осуществления этих операций в условиях, предусмотренных изготовителем.
Целью принимаемых мер является устранение любого риска несчастного случая в течение прогнозируемого периода срока службы машинного оборудования, включая фазы сборки и демонтажа, а также когда несчастный случай может произойти вследствие возникновения чрезвычайных обстоятельств, которые невозможно было предвидеть заранее.
(b) Выбирая наиболее подходящие меры, изготовитель должен применять следующие принципы в указанном порядке:
- по возможности устранить или сократить риски (сделать изначально безопасными как конструкцию, так и собранное машинное оборудование);
- принять все необходимые меры защиты против рисков, которые не могут быть устранены;
- информировать пользователей о возможных остаточных рисках, которые могут иметь место из-за недостаточности принятых мер защиты, с описанием всей необходимой специальной подготовки персонала и всех средств личной защиты, которыми его необходимо снабдить.
(c) При конструировании и производстве машинного оборудования, а также при составлении инструкций изготовитель должен предусмотреть не только обычное использование машинного оборудования, но и потенциальное его использование.
Машинное оборудование должно быть сконструировано таким образом, чтобы предотвратить ненадлежащее его использование, если оно повлечет за собой возникновение риска. В прочих случаях инструкции должны обратить внимание пользователя на то, каким образом машинное оборудование не следует использовать (на основании уже имеющегося опыта).
(d) При надлежащих условиях использования необходимо сократить до минимума всевозможные неудобства, чувство усталости и психологического стресса, которые испытывает оператор, принимая при этом в расчет принципы эргономики.
(e) При конструировании и производстве машинного оборудования изготовитель обязан принимать во внимание скованность и ограниченность движений оператора, которые являются следствием необходимых или предусмотренных средств личной защиты (таких как специальная обувь, перчатки и т.п.).
(f) Машинное оборудование должно быть снабжено всем основным специальным оборудованием, необходимым для пуска, текущего обслуживания и безопасного использования.

74 temperature-rise inside assembly
увеличение температуры внутри НКУ

[Интент]Параллельные тексты EN-RU
Temperature-rise inside assemblies
An excessive temperature-rise inside assemblies represents one of the main problems which are often subject for discussion and to which users pay the most attention.
It is evident that an anomalous heating inside switchgear can jeopardize the safety of people (possible fires) and plants (malfunctioning of the apparatus).
For this reason, the Standard IEC 60439-1 gives a lot of space to the permissible temperature-rise limits in an assembly and to the methods to determine such limits either directly as type test or by analytic extrapolation.
The term type test defines the tests intended to assess the validity of a project according to the expected performances.
Such tests are usually carried out on one or more prototypes and the results of these type tests are assumed to obey to deterministic laws.
Therefore these results can be extended to all the production, provided that it complies with the design of the tested samples.
The type tests prescribed by the Standard IEC 60439-1 include:
• verification of temperature-rise limits
• verification of the dielectric properties
• verification of the short-circuit withstand strength of the main circuits
• verification of the short-circuit withstand strength of the protective circuit
• verification of the effective connection between the exposed conductive parts and the protective circuit
• verification of clearances and creepage distances
• verification of mechanical operation
• verification of the degree of protection
As said above the verification of temperature-rise limits is one of the most critical aspect for an assembly;
the Standard states the temperature-rise limits referred to an average ambient air temperature of ≤35°C which the switchgear complying with the Standard must not exceed (Table 1).
[ABB]Увеличение температуры внутри НКУ
Чрезмерное увеличение температуры внутри НКУ свидетельствует о наличии одной из основных проблем, часто являющихся предметом рассмотрения, и на которые потребители обращают наибольшее влияние.
Совершенно очевидно, что аномальный нагрев элементов внутри НКУ может создать опасность для людей (например, возникновение пожара) и для электроустановки (неправильная работа аппаратуры).
Поэтому стандарт МЭК 60439-1 уделяет большое внимание рассмотрению предельных значений температуры в НКУ и методам их определения, как путем проведения прямых испытаний, так и с помощью экстраполяции значений, полученных в результате испытаний.
Термин типовые испытания определяет испытания, целью которых является доказательство, что испытываемое устройство отвечает определенным техническим условиям.
Такие испытания обычно проводят на одном или нескольких типопредставителях, и считают, что полученные результаты являются детерминированными.
Поэтому их можно применить ко всем изделиям, конструкция которых соответствует испытанным образцам.
В перечень проверок и испытаний, проводимых на НКУ в соответствии со стандартом МЭК 60439-1, входят:
• проверка предельных значений превышения температуры;
• проверка диэлектрических свойств;
• проверка прочности при коротких замыканиях
• проверка прочности при коротких замыканиях цепи защитного заземления
• проверка прочности соединения открытых проводящих частей и цепи защитного заземления
• проверка воздушных зазоров и длин путей утечки;
• проверка механической работоспособности
• проверка степени защиты
Как сказано выше проверка предельных значений превышения температуры является одним из наиболее важных параметров НКУ.
Согласно стандарту превышение предельного значения температуры относительно средней температуры окружающего воздуха, равной 35° C, не должно превышать значений, указанных в таблице 1.
