The purpose of the utility model provides a kind of watt-hour meter junction box, in order to solve the dangerous and problem of unstable of watt-hour meter verification in the prior art.
To achieve these goals, the utility model has adopted following technical scheme:
The watt-hour meter junction box of the utility model; Comprise terminal block; Have first connection terminal and second connection terminal that are connected with any path of watt-hour meter on the terminal block; Be provided with the patchhole that the plug in terminals that is used to make calibration equipment inserts between first connection terminal and second connection terminal, patchhole is connected with the pressure-wire of respective channels.
Further, the diameter of the aperture of patchhole and plug in terminals is complementary.
Further, first connection terminal and second connection terminal are electric conductor.
Further, terminal block is an insulating material.
Further, watt-hour meter junction box also comprises dust cap, and dust cap and terminal block are complementary, and is used to cover terminal block.
Further, dust cap is a transparent material.
Compared with prior art; The beneficial effect of the utility model is: adopt the plug into mode of voltage circuit of patchhole to help farthest to lower the possibility that potential safety hazard takes place, and make the field personnel when operation, keep maximum safe distance from the equipment live part.
