Problems solved by technology
[0003] At present, in the insulation test of single-phase smart energy meters, the wiring is usually performed manually and a single meter is tested each time. Different connection lines need to be replaced according to different test lines, and the test requires a lot of time and manpower. , there are problems such as cumbersome work and low efficiency
In addition, manual wiring has the problems of easy wiring errors, poor contact, and poor safety.

The invention provides an insulation test device of a single-phase intelligent electric energy meter. The apparatus comprises a pedestal, and a push rod fixation device, a guiding positioning device and a test terminal device which are fixed on the pedestal. The push rod fixation device is arranged at one side of the guiding positioning device, the test terminal device is arranged at the other end of the guiding positioning device, and a tested electric energy meter is placed on the guiding positioning device; and the push rod fixation device pushes the tested electric energy meter to move towards the test terminal device along the guiding positioning device, electrode terminals of the tested electric energy meter are enabled to be in adaptive plugging connection with probes in the test terminal device, and the test terminal device is connected with an external insulation tester for carrying out an insulation test on the tested electric energy meter. According to the invention, errors of manual wiring are reduced, a tedious manual wiring link is reduced, the requirement for switching different test lines is satisfied, multiple test devices can also be connected in series for simultaneously carrying out insulation tests of multiple electric energy meters, the efficiency is improved, and the time is saved.
Description
technical field [0001] The invention relates to a test device for an electric energy meter, in particular to an insulation test device for a single-phase intelligent electric energy meter. Background technique [0002] With the increasing development of the smart grid, the demand for intelligent user terminals in countries around the world is also increasing, and the smart meter should meet the country's requirements for its dielectric quality. Under normal use conditions, in order to ensure the safe use of the meter and its associated auxiliary devices, the meter and its associated auxiliary safety devices must meet sufficient dielectric quality. In this regard, GB / T17215.211-2006 has made relevant regulations on the dielectric quality of the instrument, and at the same time explained the test scope of the insulation performance test. According to the relevant provisions of GB / T 17215.211-2006 on the dielectric quality of the meter, the dielectric quality test of the smart...
