电气成套设备的通用安全措施都有哪些呢?下面小编给大家介绍一下:
What are the general safety measures for electrical equipment? Here's a brief introduction:
(1)电气绝缘。保持配电线路和电气设备的绝缘良好,是保证人身安全和电气设备正常运行的基本要素。电气绝缘的性能是否良好,可通过测量其绝缘电阻、耐压强度、泄漏电流和介质损耗等参数来衡量。
(1) Electrical insulation. Keeping good insulation of distribution lines and electrical equipment is the basic element to ensure personal safety and normal operation of electrical equipment. The performance of electrical insulation can be measured by measuring its insulation resistance, withstand voltage strength, leakage current, dielectric loss and other parameters.
(2)安全距离。电气安全距离,是指人体、物体等接近带电体而不发生危险的安全可靠距离。如带电体与地面之间、带电体与带电体之间、带电体与人体之间、带电体与其他设施和设备之间,均应保持一定距离。通常,在配电线路和变、配电装置附近工作时,应考虑线路安全距离,变、配电装置安全距离,检修安全距离和操作安全距离等。
(2) Safe distance. The electrical safety distance refers to the safe and reliable distance that the human body, objects, etc. are close to the electrified body without danger. For example, a certain distance shall be kept between the charged body and the ground, between the charged body and the charged body, between the charged body and the human body, and between the charged body and other facilities and equipment. Generally, when working near distribution lines and power transformation and distribution devices, the safe distance of lines, power transformation and distribution devices, maintenance and operation shall be considered.
(3)安全载流量。导体的安全载流量,是指允许持续通过导体内部的电流量。持续通过导体的电流如果超过安全载流量,导体的发热将超过允许值,导致绝缘损坏,甚至引起漏电和发生火灾。因此,根据导体的安全载流量确定导体截面和选择设备是十分重要的。
(3) Safe current carrying capacity. The safe current carrying capacity of a conductor refers to the amount of current allowed to continuously pass through the conductor. If the current continuously passing through the conductor exceeds the safe current carrying capacity, the heating of the conductor will exceed the allowable value, resulting in insulation damage, even electric leakage and fire. Therefore, it is very important to determine the conductor section and select the equipment according to the safe current carrying capacity of the conductor.
(4)标志。明显、准确、统一的标志是保证用电安全的重要因素。标志一般有颜色标志、标示牌标志和型号标志等。颜色标示表示不同性质、不同用途的导线;标示牌标志一般作为危险场所的标志;型号标志作为设备特殊结构的标志。
(4) Logo. Obvious, accurate and unified signs are important factors to ensure the safety of electricity use. Signs generally include color signs, signboard signs, model signs, etc. Color marks indicate conductors of different properties and purposes; Signboard signs are generally used as signs of dangerous places; The model sign is used as the sign of the special structure of the equipment.
