Abstract
The utility model aims to provide a pouring body structure of a three-phase combination type outdoor current transformer. The pouring body structure comprises a three-phase current transformer and zero sequence current transformers, wherein the three-phase current transformer and the zero sequence current transformers are poured in an integrated mode, and one surface of the pouring body structure outputs a secondary terminal of the three-phase current transformer and one zero sequence current transformer. The pouring body structure has the advantages that four current transformers are integrated in one pouring structure, the secondary terminals are integrated, wiring and maintenance are convenient, the combination type enables size space of the current transformers to be saved, and only one installation mechanism is needed for the combination type current transformers.
Description
Technical field
The utility model relates to the instrument transformer technical field, relates in particular to a kind of pour mass structure of three phase combined Outdoor Current Transformer.
Background technology
The current transformer principle is according to electromagnetic induction principle.Current transformer is comprised of iron core and the winding of closure.Its umber of turn seldom; string is in the circuit of the electric current that needs are measured; therefore it often has whole electric currents of circuit to flow through; the secondary winding turn ratio is more; be serially connected in measuring instrument and the protection loop, current transformer is when work, and its 2 minor loops are closed all the time; therefore the impedance of measuring instrument and protection loop series coil is very little, and the operating state of current transformer is near short circuit.
In the prior art, sometimes need to use simultaneously four current transformers, then needing is that four current transformers arrange respectively installation site and wiring, the inconvenient wiring of this structure and maintenance, and it is larger to take up room.
The utility model content
For the problems referred to above, problem to be solved in the utility model provides a kind of pour mass structure that makes things convenient for the three phase combined Outdoor Current Transformer of wiring and maintenance.
The technical solution of the utility model is as follows:
A kind of pour mass structure of three phase combined Outdoor Current Transformer, three phase current mutual inductors and a zero sequence current mutual inductor of comprising the formed by integrally casting moulding, one side three phase current mutual inductors of output of described pour mass structure and the secondary wiring terminals of a zero sequence current mutual inductor.
Further, described pour mass structure is provided with an installing mechanism.
The beneficial effects of the utility model are: owing to adopt technique scheme, in a cast structure, four current transformers have been gathered, secondary wiring terminals concentrates in together, make things convenient for wiring and maintenance, composite type is saved the current transformer volumetric spaces more, and Combined type current transformer only needs an installing mechanism, and is easy for installation.
Description of drawings
Fig. 1 is vertical view of the present utility model;
Fig. 2 is end view of the present utility model.
Wherein: 1, phase current mutual inductor 2, zero sequence current mutual inductor 3, secondary wiring terminals
Embodiment
Below in conjunction with accompanying drawing a kind of preferred embodiment of the present utility model is made brief description.
As shown in Figure 1, 2:
A kind of pour mass structure of three phase combined Outdoor Current Transformer, three phase current mutual inductors 1 and a zero sequence current mutual inductor 2 of comprising the formed by integrally casting moulding, one side three phase current mutual inductors 1 of output of described pour mass structure and the secondary wiring terminals 3 of a zero sequence current mutual inductor 2, described pour mass structure is provided with an installing mechanism.
Install when using, only need the structural mounting structure of pour mass is fixed in the applied environment, unified wiring.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
