Abstract
The utility model discloses a test tool for a carrier module of an electric energy meter. The test tool comprises a battery BG1 connected with a heavy current common grounding terminal of a first carrier interface chip and an alarm device connected with a light current common grounding terminal of a second carrier interface chip, and the alarm device is also connected with the battery. The test tool can test whether the heavy current common grounding terminal and the light current common grounding terminal are directly connected.
Description
Technical field
The utility model relates to electric energy meter technical field, specifically a kind of test fixture of electric energy meter carrier module.
Background technology
Carrier module is the common module in electric energy meter.This carrier module generally has two carrier interfaces.Because the separation to strong and weak electricity in electric energy meter there are differences, therefore some electric energy meters can be connected photoelectrical coupler with light current common ground end at the forceful electric power common ground end of electric energy meter, and other electric energy meter can directly be connected the forceful electric power common ground end of electric energy meter with light current common ground end.Due to the textural difference of above-mentioned electric energy meter, make electric grid operating personnel when operation, owing to being hard to tell, be any electric energy meter, be therefore easy to get an electric shock, thereby cause personal injury.So, urgently need a kind of test fixture that can test forceful electric power common ground end and the whether direct-connected electric energy meter carrier module of light current common ground end, to address the above problem.
Utility model content
The technical problems to be solved in the utility model is, overcomes the defect of above prior art, and a kind of test fixture that can test forceful electric power common ground end and the whether direct-connected electric energy meter carrier module of light current common ground end is provided.
The technical solution of the utility model is, a kind of test fixture of electric energy meter carrier module is provided, comprise the battery BG1 being connected with the forceful electric power common ground end of first carrier interface chip and the warning device being connected with the light current common ground end of the second carrier interface chip, described warning device is also connected with battery.
The test fixture of described electric energy meter carrier module also comprises a battery detecting switch S 1, and the two ends of described battery detecting switch S 1 are connected with warning device, battery respectively.
Described warning device comprises audible alarm unit and light warning device; Described light warning device comprises resistance R 1 and LED1 lamp, and one end of described resistance R 1 is connected with the positive pole of battery BG1, and the other end of described resistance R 1 is connected with the positive pole of LED1 lamp; Described audible alarm unit comprises resistance R 2 and hummer B1, and one end of described resistance R 2 is connected with the positive pole of battery BG1, and the other end of described resistance R 2 is connected with the positive pole of hummer B1.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
When the test fixture of the utility model electric energy meter carrier module is worked, battery BG1 is connected with the forceful electric power common ground end of first carrier interface chip, warning device is connected with the light current common ground end of the second carrier interface chip; When the forceful electric power common ground end of electric energy meter and light current common ground end are connected with photoelectrical coupler, the forceful electric power common ground end of first carrier interface chip is what to separate with the light current common ground end of the second carrier interface chip, so this test fixture can not reported to the police; When the forceful electric power common ground end of electric energy meter is directly connected with light current common ground end, the light current common ground end of the forceful electric power common ground end of first carrier interface chip and the second carrier interface chip forms path, so this test fixture is reported to the police.Therefore, whether the utility model can be tested forceful electric power common ground end and directly be connected with light current common ground end, thereby has avoided electric grid operating personnel to get an electric shock when operation.
