Detailed Description
The present invention is not limited by the following examples, and specific embodiments may be determined according to the technical solutions and practical situations of the present invention.
In the present invention, for convenience of description, the description of the relative positional relationship of the components is described according to the layout pattern of fig. 1 of the specification, such as: the positional relationship of front, rear, upper, lower, left, right, etc. is determined in accordance with the layout direction of the drawings of the specification.
The utility model is further described with reference to the following examples and figures:
implementing one step: as shown in the attached drawing 1, the electric energy metering verification current conversion column sleeve comprises a first cylindrical section 1 and a second cylindrical section 2 which are sequentially connected from top to bottom, the first cylindrical section 1 and the second cylindrical section 2 are electric conductors, the central axis of the first cylindrical section 1 and the central axis of the second cylindrical section 2 are collinear, a current binding post jack 3 is coaxially arranged on the bottom surface of the second cylindrical section 2, and the diameter of the current binding post jack 3 is larger than that of the first cylindrical section 1. According to the requirement, the diameter of the current terminal jack 3 and the diameter of the first cylindrical section 1 can be designed according to the current terminal hole diameters of the electric energy meters with two different ranges to be verified, for example, in the electric energy meters with the two different ranges, the current terminal hole diameter of the electric energy meter with one range is S1, the current terminal hole diameter of the electric energy meter with the other range is S2, S1 is larger than S2, therefore, the diameter of the current terminal jack 3 can be designed to be S1, the diameter of the first cylindrical section 1 is designed to be S2, therefore, when the electric energy meter verification device is used for verifying the electric energy meters with the two different ranges, when the electric energy meter with the larger current terminal hole diameter is verified, only the current terminal on the connection frame in the verification device needs to be inserted into the corresponding current terminal hole diameter, and when the electric energy meter with the smaller current terminal hole diameter is verified, with this electric energy measurement examination current conversion post sleeve pipe suit to the current terminal of link span, then with first cylinder section 1 insert to the current terminal aperture that corresponds in can, through the setting of electric energy measurement examination current conversion post sleeve pipe, from this when the electric energy meter to two kinds of different current terminal apertures examines and determine the operation, need not to change the not current terminal of equidimension, only need on the original current terminal of link span the suit or pull down this electric energy measurement examination current conversion post sleeve pipe can, the time that the change current terminal consumed has been avoided, very big work efficiency who examines and determine the operation has been provided, the operation intensity is reduced.
The first embodiment can be further optimized or/and improved according to actual needs:
as shown in fig. 1, the diameter of the current terminal receptacle 3 is equal to or slightly less than 7 mm, and the diameter of the first cylindrical section 1 is equal to or slightly less than 4 mm. Therefore, the requirements of the verification operation of two different-range electric energy meters of a 10 (100) A direct access type three-phase electric energy meter and a 0.3 (1.2) A access type three-phase electric energy meter through a mutual inductor in the current market can be met.
As shown in the attached figure 1, the upper end surface of the first cylindrical section 1 is arranged as an inclined surface. Thereby facilitating mating with terminals within the electric energy meter.
Example two: as shown in the attached drawing 2, the wiring rack for electric energy meter verification comprises a rack body 4, wherein a transverse guide rail 5 is arranged on the rack body 4, six sliding blocks 6 are arranged on the transverse guide rail 5 in a sliding mode, a current wiring terminal 7 is arranged at the upper end of each sliding block 6, a connecting sheet 8 is arranged at the lower end of each sliding block 6, a wiring hole 9 is formed in each connecting sheet 8, the wiring rack further comprises six current metering verification current conversion column sleeves, and one current wiring terminal 7 is uniformly inserted into one current wiring terminal jack 3 in a corresponding mode. According to the requirement, the current binding post 7 is in clearance fit with the current binding post jack 3, the current conversion post sleeve is sleeved outside the upper end of the current binding post 7 for electric energy metering and verification, therefore, when the electric energy meters with two different current binding post apertures are verified, when the electric energy meters with smaller current binding post apertures are verified, only the upper end of the first cylindrical section 1 is directly inserted into the current binding post aperture of the electric energy meter, when the electric energy meters with larger current binding post apertures are verified, only the current conversion post sleeve for electric energy metering and verification is taken down from the current binding post 7, the current binding post 7 is directly inserted into the current binding post aperture of the electric energy meter, namely, when the electric energy meters with two different current binding post apertures are verified, the current binding posts 7 with different sizes do not need to be replaced, and the whole verification operation process is more time-saving and labor-saving, the working efficiency is improved.
