Description

实现电机异常监控的方法、装置、计算机存储介质及终端Method, device, computer storage medium and terminal for realizing motor abnormality monitoring

技术领域technical field

本文涉及但不限于电机监测技术,尤指一种实现电机异常监控的方法、装置、计算机存储介质及终端。This article involves but is not limited to motor monitoring technology, especially a method, device, computer storage medium and terminal for realizing motor abnormality monitoring.

背景技术Background technique

随着电气自动化的发展,许多的行业需要大功率的电机来帮助其生产;在生产过程中,电机往往是超负荷运作,会导致电机故障异常。With the development of electrical automation, many industries need high-power motors to help their production; in the production process, the motors are often overloaded, which will lead to abnormal motor failures.

相关技术中,大功率的电机主要基于电热原理进行保护,通过设置热过载继电器作为保护装置,热过载继电器是应用电流热效应原理,以电工热敏双金属片作为敏感元件的过载继电器,又称热继电器;电工热敏双金属片是由两种线膨胀系数相差较大的合金加热轧制而成的;受热时,双金属片由高膨胀层(主动层)向低膨胀层(被动层)弯曲。当电流过大(超过整定值)时,元件因“热”而动作,从而,其连动的动断触点切断所控电路及被保护设备的电源,对电机进行中断控制。图1为相关技术电机中断控制的示意图,如图1所示,由电磁式中间继电器(FR)和交流接触器(KM)构成热过载继电器,电机通过由热过载继电器进行过热时的中断保护。热过载继电器存在灵敏度容易降低的问题,热过载继电器灵敏度降低,容易引起烧电机线圈故障;大功率的电机维修用时长、成本高,一旦出现烧电机线圈故障,将极大的影响生产效率。In related technologies, high-power motors are mainly protected based on the electrothermal principle. Thermal overload relays are used as protection devices. Thermal overload relays are overload relays that use the principle of current thermal effects and use electrical thermal bimetallic strips as sensitive components. They are also called thermal overload relays. Relay; electrical thermosensitive bimetal sheet is formed by heating and rolling two alloys with large difference in linear expansion coefficient; when heated, the bimetal sheet bends from the high expansion layer (active layer) to the low expansion layer (passive layer) . When the current is too large (beyond the set value), the element will act due to "heat", so that its interlocking movable contact cuts off the power supply of the controlled circuit and the protected equipment, and interrupts the control of the motor. Figure 1 is a schematic diagram of motor interruption control in the related art. As shown in Figure 1, a thermal overload relay is composed of an electromagnetic intermediate relay (FR) and an AC contactor (KM), and the motor is interrupted by the thermal overload relay for overheat protection. The thermal overload relay has the problem that the sensitivity is easy to decrease. The thermal overload relay sensitivity decreases, which may easily cause the failure of the motor coil; the maintenance of high-power motors takes a long time and the cost is high. Once the motor coil failure occurs, it will greatly affect the production efficiency.

如何降低电机故障,降低电机故障对生产造成的影响,成为一个有待解决的问题。How to reduce motor failures and reduce the impact of motor failures on production has become a problem to be solved.
