Non-electric continuous type hardware fitting energy consumption testing method

Abstract

The invention discloses a non-electric continuous type hardware fitting energy consumption testing method. The method comprises the following steps of: (1) selecting a test lead by using the following method; (2) fastening a temperature measuring probe on the test lead; (3) installing a single copper wire at a potential test point; (4) connecting a current transformer ammeter; (5) powering on; (6) measuring and recording the energy consumption P1 of the test lead; (7) installing a tested hardware fitting; (8) powering on and recording the total energy consumption, and calculating the energy consumption value of a single hardware fitting; (9) repeating the test twice; and (10) calculating the average value of the energy consumption of each hardware fitting after the three repeated experiments. With the adoption of the testing method, the research on energy consumption characteristics of the non-electric continuous type hardware fitting is deepened to a quantitative level, and necessary reference data in optimization design of hardware fittings and model selection of the hardware fittings in a power grid are provided for production enterprises. Therefore, under the political and economic environment in which energy conservation and consumption reduction is proposed, research on the non-electric continuous type hardware fitting energy consumption testing method is very necessary and important in order to construct a resource-saving and environment-friendly country.

Description

technical field [0001] The invention relates to the field of testing technology, in particular to the field of testing the power loss of non-electrical connection fittings, in particular to a method for testing the current, temperature and energy consumption of non-electrical connection fittings. Background technique [0002] Non-electrical connection fittings are important electrical equipment on transmission and distribution lines, and are responsible for the important mission of safe power transmission. [0003] The non-electrical connection fittings used on the line in our country for decades are mainly made of iron, and the structure is a closed electromagnetic circuit, and it is directly installed on the exposed wire. In the electromagnetic field, due to its wide range of applications, the resulting energy consumption is also very considerable. Foreign countries began to study and test the energy consumption of iron-made electric power fittings as early as the 1980s, ...

Problems solved by technology

Foreign countries began to study and test the energy consumption of iron-made electric power fittings as early as the 1980s, and promoted the application of energy-saving electric power fittings. In the 1990s, my country also began to produce some energy-saving electric power fittings. Insufficient understanding of the sustainability effect (the relationship between a slight increase in the one-time capital investment in construction and a continuous reduction in operating costs) is insufficient, and the use area and amount are both small

In recent years, although various regional departments have conducted tests on the energy consumption of some related fittings and monitored energy consumption in actual operation, they have not conducted comprehensive and systematic tests and analysis on current, temperature and energy consumption.

[0004] At present, the existing problems in the research on energy consumption of non-electrical connection fittings are mainly reflected in: the proportion of energy consumption of non-electrical connection fittings is relatively small compared to the loss of the entire line, and the loss and its structural parameters, material characteristics, model specifications, and current density are relatively small. , electromagnetic characteristics, environmental conditions and other factors are closely related, the analysis and calculation are complex, and it is difficult to measure the energy loss of power equipment in actual operation by traditional measurement methods

However, our country lacks corresponding national standards in this regard, and there are no stereotyped measuring devices and effective testing methods. The optimal design and selection of connection fittings provide necessary reference data, which cannot objectively provide operating cost data for the power grid
