(1)早期故障较高(O~t0期间)。 主要是由于系统内在设计错误、元器件质量、安装和工艺缺陷等不合理原因引起，但随时间的增加故障率迅速降低。 这一时期的主要任务是尽早找出不可靠的因素使系统尽快稳定下来。

(⑵)偶然期故障期(t0~t1期间)比较稳定，也可称为随机故障期。 此时期故障是随机发生的，系统的故障率低而且稳定，可视为常数。 这一时期是系统的佳状态期，在运行中应以加强维护延长这段时期的时间，应做好定期检修和维护工作。

(3)损耗期(t1之后)故障率上升，这是因为常时间以来构成系统的某些零件已经老化耗损，寿命衰竭机械和电气磨损以及绝缘的老化所引起。 在这段时期中大部分元件要开始失效。 如能事先知道损耗开始的时间，事先更换元器件，延长系统的有效寿命。 推迟耗损故障期的到来。

70BV01C-ES-HESG447260R1 ABB 接触器

Model: 70BV01C-ES-HESG447260R1

ABB's new ESB Silencing building contactors offer a wide current range of 16 to 100A with toolless attachment installation and are widely used to switch on and control lighting, heating, ventilation, motors and pumps in buildings. This series of contactors uses an innovative squelch AC/DC coil to operate quietly and reliably in noise-sensitive environments, giving users peace of mind.

Key advantages: Powerful light control capability, quiet and low power consumption of 70BV01C-ES-HESG447260R1 series · Greatly reduced space footprint compared to industrial contactors · AC/DC integrated coil reduces product variety and simplifies inventory.

(1) The early failure is high (during O~t0). It is mainly caused by unreasonable reasons such as internal design errors, component quality, installation and process defects, but the failure rate decreases rapidly with the increase of time. The main task in this period is to find the unreliable factors as early as possible and stabilize the system as soon as possible.

(2) The accidental failure period (t0~t1 period) is relatively stable, and can also be called the random failure period. In this period, the failure occurs randomly, and the failure rate of the system is low and stable, which can be regarded as a constant. This period is the best state of the system, in operation should be to strengthen maintenance to extend this period of time, should do regular maintenance and maintenance work.

(3) The failure rate increases during the loss period (after t1), which is because some parts of the system have been aging for a long time, life failure caused by mechanical and electrical wear and aging of insulation. During this period most components begin to fail. If you can know in advance the time when the loss starts, replace the components in advance to extend the effective life of the system. Delay the arrival of the wear down period.
