Problems solved by technology
The seal structure of the electric energy meter in the prior art is complicated, and the manual installation method with low work efficiency can only be used
In order to meet the requirements of automatic verification of electric energy meters, the relevant personnel of the State Grid Metrology Center have designed and developed a new type of electric energy meter seal to replace the original threaded seal that is mainly sealed manually. The operation of the new electric energy meter seal is fundamentally solved. Solve the problems of low efficiency and uneven quality caused by human factors

The invention discloses an electric energy meter seal performance testing device, which comprises a mother board replacement component 1, a fixed mother board 2, a mother board transplanting component 3 and a testing component 4. The improvement of the electric energy meter seal performance testing device is characterized in that the testing device is arranged in a stereoscopic framework formed by columns which are vertically placed and lining plates which are connected with the columns and are horizontally placed; a bottom board of the mother board transplanting component 3 is arranged on a lining plate at the middle part; supporting columns are arranged at the bottom part of the mother board transplanting component 3; the fixed mother board 2 is arranged above the mother board transplanting component 3 and is connected through a linear guide rail 24 which simultaneously penetrates through the mother board replacement component 1; the testing component 4 is arranged in parallel behind the mother board transplanting component 3. The electric energy meter seal performance testing device provided by the invention has the advantages of simple structure, convenience in installation and low manufacturing cost, and can be widely applied to scientific research institutes and industrial detection departs.
Description
technical field [0001] The invention relates to a test device, in particular to a test device for the sealing performance of an electric energy meter. Background technique [0002] The energy meter seal is a device to prevent unauthorized people from opening the energy meter, so as to prevent others from changing the structure or setting of the energy meter without authorization to steal electricity. The seal of the electric energy meter generally includes the main body of the seal and the sealing wire connected with the sealing body. When in use, the sealing wire passes through the cover hole of the meter, and a special tool is used to seal the sealing body and the sealing wire firmly to prevent the meter cover from being opened. The electric energy meter seal structure in the prior art is complex, and can only be installed manually with low work efficiency. In order to meet the requirements of automatic verification of electric energy meters, the relevant personnel of the...
