Abstract
The utility model which relates to a main loop structure of residual current circuit breaker zero-sequence current mutual inductor is characterized in that a bolt and a nut go through the zero-sequence current mutual inductor and a conductive copper bar and a conductive copper rod which are firmly fixed are insulated and isolated with insulation sleeves. The new design proposal provides possibility of designing large current model residual current circuit breaker, and the designed zero-sequence current mutual inductor is small in volume and compact in structure.
Description
(1) technical field.The utility model relates to the zero sequence current mutual inductor major loop structure that a kind of residual current circuit breaker is used, and belongs to the low-voltage electrical apparatus breaker technical field.
(2) background technology.Residual current circuit breaker is the electric elements of using always in low-voltage circuit, this electrical equipment is made up of main switch, release, electronic circuit and zero sequence current mutual inductor, wherein whether the design of zero sequence current mutual inductor major loop structure is reasonable, will have influence on big electric current residual current circuit breaker design, particularly rated current in the whether compact problem of the volume size of 200A and above residual current circuit breaker, structure.
At present, the residual electricity stream circuit breaker of big current specification is made with round copper rod brake forming mostly, and certain bending radius is all arranged, therefore, existing residual current circuit breaker, general volume is all done greatlyyer, on structure, existing structural design is very unreasonable, and,, be impossible realize basically according to its major loop structure in rated current 630A, 800A and above residual current circuit breaker design and manufacturing.The improvement design of major loop structure must improve as early as possible.
(3) summary of the invention.The purpose of this utility model provides a kind of major loop structure that is used for the zero sequence current mutual inductor of residual current circuit breaker, this structure can satisfy the residual current circuit breaker structural requirement of 200A, 400A specification, but also can expand to the big specification residual current circuit breaker of 630A, 800A, this newly-designed technical scheme has been started the new approaches of big specification residual current circuit breaker minor structure.
In order better to achieve the above object, its solution is: at several conducting coppers of major loop, carry out fastening and add insulation with screw, can realize big specification electric current residual current circuit breaker.
(4) description of drawings.
Fig. 1 is the major loop structure vertical view of the utility model zero sequence current mutual inductor.
Fig. 2 is the major loop structure upward view of the utility model zero sequence current mutual inductor.
Among Fig. 1, Fig. 2,1 is that screw, 2 is that nut, 3,4 is that conducting copper, 5 is that zero sequence current mutual inductor body, 6 is for insulating sleeve, 7, for conducting electricity copper rod.
(5) embodiment
With reference to Fig. 1, Fig. 2, with screw 1 and nut 2 pass zero sequence current mutual inductor 5 with conducting copper 3 and 4 and conduction copper rod 7 fastening, ask mutually with insulating sleeve 6 isolation of insulating at each.
Claims (1)
1, a kind of zero sequence current mutual inductor major loop structure, form by conducting copper, current transformer body, conduction copper rod, it is characterized in that major loop structure is the body that passes zero sequence current mutual inductor (5) with screw (1) and nut (2), conducting copper (3) and (4) and conduction copper rod (7) are fastening, alternate at each with insulating sleeve (6) isolation of insulating.
