A double-layer multi-functional electric meter verification equipment

technical field

The invention relates to the technical field of electric energy meter detection, in particular to a double-layer multifunctional electric meter verification device.

Background technique

Before the meter is put into use, a variety of tests are required, and the verification equipment undertakes most of the tasks, including accuracy requirement test, electrical requirement test, communication function test, consistency test, cost control test, etc. To test the ammeter, firstly, the probes of the automatic patch cord device need to be in reliable contact with the corresponding terminals of the ammeter, so as to provide the ammeter with the current and voltage environment required for its work. Obviously, the automatic patch cord device in the verification equipment determines the type of ammeter that the verification equipment is suitable for.

Most of the verification equipment in the prior art is single-layer, and the shortcomings of the single-layer verification equipment mainly include the following three points:

First, there are few types of electric meters that can be detected. The correct connection of the ammeter is the premise of realizing various tests of the ammeter. Because the structure and the size of the meter stand carried on the patch cord device must match the ammeter, a single-layer patch cord device can only complete the connection of a kind of ammeter. By symmetrically configuring two types of single-layer patch cord devices, the single-layer verification equipment can complete the detection of two types of electric meters at most. And electric meters are divided into single-phase, three-phase, and terminal, and there are sub-categories in each category. Obviously, single-layer verification equipment cannot meet the requirements of the meter inspection line system.

Second, the space utilization rate is low. To detect more than two types of meters, it is necessary to configure multiple single-layer verification devices. The floor area of the verification equipment is the largest among all the equipment of the meter inspection line.

Third, the cost is high. The configuration of the double-layer verification equipment and the single-layer verification equipment is the same on the standard parts, but not twice that of the single-layer verification equipment. At the same time, the number of machined parts has also been reduced to a certain extent.

In view of this, it is an urgent technical problem to be solved in this field to overcome the above defects in the prior art and provide a new electric meter verification equipment.
