Problems solved by technology

[0003] Therefore, in practice, testing institutions seldom test and verify the reliability indicators of the energy meters provided by the manufacturers, especially the procurement department of the power grid, which cannot evaluate the reliability of the energy meters before purchasing and installing applications. There is also no corresponding process and equipment to judge and detect its average life

Abstract

The invention provides an accelerating service life test device for electronic electrical-energy meters. The test device is a laboratory which is formed by a plurality of test stands used for placing electronic electrical-energy meters, a fire extinguisher, a temperature and humidity sensor, a temperature and humidity controller, a smog sensor, an air circulation system device, a total control box and a control device. The accelerating service life test device adopts a method of using a high-temperature and high-humidity environment to realize accelerated service life testing to evaluate the reliability of the electrical energy meters so that test time can be reduced significantly and experiment cost is saved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an accelerated life testing device for an electronic electric energy meter. Background technique [0002] The reliability characteristic quantity of the electric energy meter is stipulated as the average life. Reliability is a key indicator of electric energy meters used in trade settlement. Generally, the average life expectancy of electronic electric energy meters in China is 10 years; however, specific reliability is rarely given in general standards or technical specifications. For example, the test method specified in GB / T 15284-2002 is simply described as "the reliability verification test is carried out according to the method specified in JB / T 50070". In fact, if the test is carried out in strict accordance with the methods stipulated in the machinery industry standard JB / T 50070-2002 "Reliability Requirements and Assessment Methods for Electric Energy Meters", e...
