Abstract
The utility model discloses a kind of Novel measuring combined instrument transformer, comprise voltage transformer one, current transformer one, base, current transformer two, voltage transformer two, chassis interior connects groove and fairlead, voltage transformer one, current transformer one, current transformer two and voltage transformer two are that two rows are located on base side by side side by side, chassis interior connects groove along voltage transformer one, current transformer one, form connectivity slot bottom current transformer two and voltage transformer two and be arranged on chassis interior, fairlead and chassis interior connect groove be communicated with and in current transformer two and voltage transformer two protuberate basic unit outside, chassis interior connects groove and secondary terminals and cable once-cast is formed and allow cable draw from fairlead.This Novel measuring is simple with combined instrument transformer process operation, needs parts few, compact conformation, lightweight, and sealing is strong, meets instructions for use, improves dependability, have the value promoted the use of.
Description
Technical field
The utility model relates to a kind of combined instrument transformer, is specifically related to a kind of Novel measuring combined instrument transformer.
Background technology
In fact combination transformer is exactly the combination of voltage transformer summation current transformer, for measuring power administration's fee.Table is freely hung for power administration, can be the combination of a voltage transformer and a current transformer, for measuring single-phase power; Can be the combination of two voltage transformers and two current transformers, for measuring three phase power by two watts of methods in three-phase three-wire system; Also can be the combination of three voltage transformers and three current transformers, measure for three-phase electricity.Combined mutual inductor for metering uses comparatively general, very high for combined mutual inductor for metering volume, sealing and reliability requirement.The combined mutual inductor for metering volume of current use is large, Heavy Weight and sealing poor, had a strong impact on the reliability of combined mutual inductor for metering use.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of Novel measuring combined instrument transformer, this Novel measuring combined instrument transformer, and volume is little, and sealing is strong, meets the reliability that combined mutual inductor for metering uses.
A kind of Novel measuring combined instrument transformer, comprise voltage transformer one, current transformer one, base, current transformer two, voltage transformer two, chassis interior connects groove and fairlead, voltage transformer one, current transformer one, current transformer two and voltage transformer two are that two rows are located on base side by side side by side, chassis interior connects groove along voltage transformer one, current transformer one, form connectivity slot bottom current transformer two and voltage transformer two and be arranged on chassis interior, fairlead and chassis interior connect groove be communicated with and in current transformer two and voltage transformer two protuberate basic unit outside, secondary terminals and cable connect groove once-cast at chassis interior and are formed, cable trailer is drawn by fairlead.
Further, this combined instrument transformer also comprises dust cap, and dust cap covers on combined instrument transformer top.
The beneficial effect obtained by this technological means the utility model is, this Novel measuring is simple with combined instrument transformer process operation, and need parts few, processing and fabricating cost is low.And compact conformation, lightweight, sealing is strong, meets instructions for use, improves dependability, have the value promoted the use of.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model;
In the drawings: 1, voltage transformer one; 2, current transformer one; 3, chassis interior connects groove; 4, base; 5, fairlead; 6, voltage transformer two; 7, current transformer two.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining utility model, is not intended to limit scope of the present utility model.
A kind of Novel measuring combined instrument transformer, comprise voltage transformer 1, current transformer 1, base 4, current transformer 27, voltage transformer 26, chassis interior connects groove 3 and fairlead 5, voltage transformer 1, current transformer 1, current transformer 27 and voltage transformer 26 are that two rows are located on base 4 side by side side by side, chassis interior connects groove 3 along voltage transformer 1, current transformer 1, connectivity slot is formed and to be arranged on base 4 inner bottom current transformer 27 and voltage transformer 26, fairlead 5 and chassis interior connect groove 3 be communicated with and in current transformer 27 and voltage transformer 26 protuberate basic unit 4 outside, secondary terminals and cable connect groove 3 once-cast at chassis interior and are formed, cable trailer is drawn by fairlead 5.The chassis interior of this intercommunication connects groove 3 when castable, and good airproof performance, reliability is high.And be arranged side by side by voltage transformer summation current transformer and effectively make use of space, its compact conformation, meets instructions for use.
For making its outside anti-dust performance better, improve its useful life, combined instrument transformer also comprises dust cap, and described dust cap covers on combined instrument transformer top.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
