Problems solved by technology

[0003] However, the frequency and time of use of each device after purchase are different, so their service life is not exactly the same
However, due to the state of the machine and the large number of parts, it is generally necessary for professionals to judge the wear and tear of the mechanical equipment in order to replace the equipment in time, and there is no simple way for the user to know the wear and tear of the equipment by himself.

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0029] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0030] Such as figure 1 As shown, a method for evaluating the consumption state of electric equipment of the present invention comprises the following steps: 1) connect an electric energy meter in series on the current path of each electric equipment, and use the electric energy meter to obtain the electric energy of the electric equipment at the first The first power consumption a and the second power consumption b in the time period and the second time period, the second time period is the time after the first time period, and the second time period is adjacent to the first tim...

Abstract

The invention relates to a method for assessing the loss state of electrical equipment, in particular to a method for assessing the loss state of electrical equipment quickly and easily. The method comprises: step one, an electric energy meter is connected in series to a current passage of electrical equipment; step two, an electricity consumption increasing rate is calculated; step three, an estimated electricity consumption value is calculated based on the electricity consumption increasing rate; and step four, an actual electricity consumption value is obtained, the obtained actual electricity consumption value is compared with a preset electricity consumption value, if the actual electricity consumption value is less than or equal to the estimated electricity consumption value, the electrical equipment is determined to be in a normal equipment loss state, and if the actual electricity consumption value is larger than the estimated electricity consumption value, the electrical equipment is determined to be in an abnormal equipment loss state. A protective cover is installed at the electric energy meter and consists of a cap component and a blocking part fixed in the cap component; the cap component has a cap top part and a side flange; and a reverse part is formed on the side flange. With the method provided by the invention, the loss state of the electrical equipment can beassessed timely and conveniently by the user, so that the safety of life and property can be protected.

Description

technical field [0001] The invention relates to a method for evaluating the loss state of electrical equipment, in particular to a method for evaluating the loss state of electrical equipment that is convenient, fast, and highly sensitive. Background technique [0002] The life cycle of various equipment refers to the total length of time from when the equipment is put into use until it is finally withdrawn from use due to the complete loss of equipment functions. An important indicator for measuring the final retirement of equipment is reliability. The life of equipment is usually an important decision basis for equipment renewal and transformation. Equipment renewal is usually carried out to improve product quality, promote product upgrading, and save energy. Among them, equipment renewal can also be considered from the economic life of equipment, and equipment renovation is sometimes based on the purpose of prolonging the technical life and economic life of equipment. ...
