Abstract
Multifunctional combined experimental wiring box, the built-in some terminals subgroups of box body, each terminals subgroup comprises four binding posts, below each binding post, current terminal is set, above first binding post, electric energy meter lead wiring terminal is set, arrange mutual inductor lead wiring terminal above 4th binding post, arrange short circuit hole respectively in the middle of second binding post, the 3rd binding post and the 4th binding post, short circuit is connected in flakes by electric current between hole.Electric current is connected by terminals subgroup by the utility model, arranges the on-off function that electric current realizes binding post in flakes between binding post, and combined instrument transformer secondary side voltage ratio control in convenient operation, reduces the risk of equipment failure and personal injury.
Description
Technical field
The utility model relates to a kind of Application of Power Metering Instruments, is specifically related to a kind of multifunctional combined experimental wiring box being convenient to measure voltage ratio control.
Background technology
Operating Electricity customers, due to the change of load, power supply enterprise's metrological personnel can arrive scene and carry out voltage ratio control, meets the state of measuring apparatus safe operation according to this, the environment of keeping the safety in production with Electricity customers.
At present secondary side mostly is to combined instrument transformer voltage ratio control, and original Combined Trials terminal box can only meet the monotropic application than mutual inductor, when voltage ratio control as misoperation, the faults such as current transformer open circuit or voltage short circuit can be caused, the generation of the security incidents such as personal injury time serious, can be caused.
Utility model content
The utility model provides a kind of multifunctional combined experimental wiring box, and the problem of equipment failure and personal injury easily occurs the combined instrument transformer secondary side voltage ratio control existed to solve prior art.
The utility model solves the technical scheme that its technical matters adopts:
A kind of multifunctional combined experimental wiring box, the built-in some terminals subgroups of box body, each terminals subgroup comprises four binding posts, below each binding post, current terminal is set, above first binding post, electric energy meter lead wiring terminal is set, arrange mutual inductor lead wiring terminal above 4th binding post, arrange short circuit hole respectively in the middle of second binding post, the 3rd binding post and the 4th binding post, short circuit is connected in flakes by electric current between hole.
Above-mentioned 4th binding post is inner disconnection, realizes on-off function in flakes by electric current.
Above-mentioned electric current is copper material with short circuit hole in flakes.
Electric current is connected by terminals subgroup by the utility model, arranges the on-off function that electric current realizes binding post in flakes between binding post, and combined instrument transformer secondary side voltage ratio control in convenient operation, reduces the risk of equipment failure and personal injury.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure 1 terminals subgroup, 2 binding posts, 3 current terminals, 4 electric energy meter lead wiring terminal, 5 mutual inductor lead wiring terminal, 6 electric currents in flakes, 7 electric currents in flakes, 8 electric currents in flakes.
Embodiment
As shown in the figure, a kind of multifunctional combined experimental wiring box, the built-in some terminals subgroups 1 of box body, each terminals subgroup 1 comprises four binding posts 2, current terminal 3 is set below each binding post, above first binding post, electric energy meter lead wiring terminal 4 is set, above 4th binding post, mutual inductor lead wiring terminal 5 is set, in the middle of second binding post, the 3rd binding post and the 4th binding post, short circuit hole is set respectively, between short circuit hole by electric current in flakes 6, electric current 78 to be connected with electric current in flakes in flakes.4th binding post is inner disconnection, 8 realizes on-off function in flakes by electric current.Electric current in flakes 6, electric current in flakes 7, electric current 8 is copper material with short circuit hole in flakes.
The utility model Multi-function experimental terminal box is transformed on original terminal box basis, mainly current segment is repacked into four groups of connection terminals, S1, S2, S3, S4 whole thereto low-side current terminal; Enter electric energy meter wire, the electric energy meter lead wiring terminal above thereto, return the mutual inductor lead wiring terminal above mutual inductor wire thereto; When accessing S1, S2, connected in flakes by top 1# electric current, 3# electric current disconnects in flakes; When accessing S1, S3, connected in flakes by top 2# electric current, 3# electric current disconnects in flakes; When accessing S1, S4,3# electric current is connected in flakes.
