Embodiment Construction

[0022] see figure 1 , providing an embodiment of a fault detection method for electrical equipment, including the following steps:

[0023] S110: Control the startup of the electrical equipment and record the start time point when the electrical equipment enters the working state.

[0024] For some electrical equipment, when the continuous working time exceeds a certain period of time, it will be considered abnormal. The compressor will automatically stop running. When the temperature in the refrigerator rises to the cut-off point temperature, the compressor will resume operation. If the refrigerator compressor does not stop running when the temperature is lower than or equal to the cut-off point temperature, the refrigerator may If the compressor breaks down, on the other hand, that is to say, if the compressor of the refrigerator has been working continuously for more than a certain period of time, it is considered to be broken down. Therefore, in this embodiment, by judgi...

Abstract

The invention discloses an electric equipment fault detection method and device. The method is characterized by recording a start time point of electric equipment entering a work state, recording cumulated time after the start time point and recording continuous working time of the electric equipment working continuously after the start time point; and when the cumulated time is not larger than a preset period time and the continuous working time is larger than preset time, giving a prompt message for reminding that the electric equipment has fault. When fault detection is carried out through the electric equipment fault detection method and device, fault detection of the electrical equipment is carried out through a mode of judging whether the continuous working time of the electric equipment in the preset period time surpasses the preset time instead of an original mode of judging whether electrical parameters vulnerable to external interference are normal; if the electric equipment has fault, the fault reminding is given; and since the continuous working time is not easy to be affected by the outside world, fault detection can be carried out accurately based on the continuous working time and the preset time, and detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a fault detection method and device for electrical equipment. Background technique [0002] For electrical equipment, in order to ensure its safe operation, it is necessary to conduct periodic fault detection on electrical equipment to quickly find problems with electrical equipment and perform maintenance to ensure safe operation of electrical equipment. The compressor of the refrigerator is one of these electrical equipment. By ensuring the normal operation of the compressor, the normal operation of the refrigerator is ensured. At present, the commonly used detection method can be detected by obtaining the electrical parameter values ​​flowing into the electrical equipment, that is, by detecting whether the electrical parameter values ​​are abnormal to determine whether the electrical equipment is faulty. [0003] However, when performing fault detection through t...
