Technical field
The utility model relates to electricity field, relates in particular to a kind of disjunction calibrating terminal of instrument and meter in the system being measured or overhauled usefulness.
Background technology
Sending out transmission of electricity, supplying the electrical secondary system of distribution field, especially power plant and transformer station, can often use the disjunction calibrating terminal, the instrument and meter in the system is measured or overhauled.Since the consumption of disjunction calibrating terminal many and in electric power system, use quite extensive, so practicality and operability are had higher requirement.It is the connected mode of disjunction calibrating terminal of the prior art shown in Fig. 1, in this structure, what left and right current bar 3 and testing tube 4 adopted is that whole copper coin repeatedly connects after the bending, course of processing more complicated, and screw assembly and testing tube divide and are arranged in the prior art, and the material of use is more.
Therefore, necessaryly prior art is improved to solve the defective that exists in the prior art.
Summary of the invention
The purpose of this utility model is to provide a kind of disjunction calibrating terminal, and this calibrating terminal is applied to measure in the instrument and meter or overhaul, and its practicality and economy are all higher.
The utility model adopts following technical scheme: a kind of disjunction calibrating terminal, it is assembled in the external shell, described disjunction calibrating terminal comprises the disjunction slide block in left current bar, right current bar and fixing described left current bar and the right current bar, described left current bar and described right current bar evenly extend to form an arch bridge, both-side ends from described left current bar and right current bar is formed with respectively a circular hole, be equipped with respectively a bolt in the circular hole of described left current bar and right current bar, described disjunction calibrating terminal also includes the testing tube that is arranged at described bolt outside.
Described testing tube includes left testing tube and right testing tube, is provided with internal thread on the inwall of described left and right testing tube, is provided with the external screw thread that matches with described internal thread on the described bolt.
Bolt on the described left current bar and left testing tube integrated molding, the bolt on the described right current bar and right testing tube integrated molding.
Extend on the described disjunction slide block and be provided with a disjunction testing tube.
Described external shell includes the shell of taking in the disjunction calibrating terminal and the removable cover that matches with shell.
Described external shell adopts industrial flame-retardant insulating material.
Compared with prior art, the utlity model has following beneficial effect:
(1). be provided with three testing tubes in the utility model disjunction calibrating terminal, use more convenient;
