Abstract
The invention relates to a double loop resistance element. The upper end and the lower end of the resistance element are symmetrically provided with grooves with the number which is an even number; intervals between adjacent grooves at a same side are same; and a rectangular groove is arranged between each adjacent grooves. Compared with resistance elements prepared with the prior art, the resistance element of the invention has the advantages of large bearing current, small resistance and the like.
Description
Technical field
The present invention relates to a kind of resistive element, especially relate to a kind of double loop resistive element.
Background technology
Adopt in the electric power system of grounding through resistance operational mode at neutral point, neutral point need be installed earth resistance, is used for satisfying needs such as system operation mode, short circuit current restriction, overvoltage level control, relaying protection cooperation.And non-metallic resistor is big with its Standard resistance range, volume is little, easy for installation, maintenance workload is little etc., and characteristic is extensively utilized.
This resistance original paper generally is the sheet entity that metal material is formed through cutting, punching out, and promptly resistive element makes up these resistive elements with the serial or parallel connection mode, can obtain the resistance that needs.
Fig. 1 is existing single loop resistive element structure, and existing single loop resistive element can't satisfy the requirement of big electric current, and it is very little that resistance can not be done.
Summary of the invention
The object of the invention is exactly for the defective that overcomes above-mentioned prior art existence a kind of double loop resistive element that electric current is big, resistance is little that bears to be provided.
The object of the invention can be realized through following technical scheme:
A kind of double loop resistive element is characterized in that, this resistive element two ends symmetry up and down has the even number Baltimore groove, and the spacing of the adjacent Baltimore groove of homonymy is identical, has rectangular channel in the middle of adjacent two pairs of Baltimore grooves.
Described rectangular channel upper end is identical with the vertical range of resistive element lower end, rectangular channel lower end to the vertical range of resistive element upper end.
Described resistance right ends is arranged with bolt fastening hole and open-type hole.
Compared with prior art, the present invention has the following advantages:
1) electric current that bears is big, is 2 times with power single loop resistive element;
2) the minimum resistance of monolithic is little, is 1/4th of stack pile single loop resistive element.
Description of drawings
Fig. 1 is existing single-circuit resistive element;
Fig. 2 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.
Embodiment
As shown in Figure 1, a kind of double loop resistive element, this resistive element two ends symmetry up and down have even number Baltimore groove 1, and the spacing of the adjacent Baltimore groove 1 of homonymy is identical, have rectangular channel 2 in the middle of adjacent two pairs of Baltimore grooves.Described rectangular channel 2 upper ends are identical with the vertical range of resistive element lower end, rectangular channel 2 lower end to the vertical range of resistive element upper end.Described resistance right ends is arranged with bolt fastening hole 3 and open-type hole.Wherein the direction of arrow is current direction, is provided with like this to realize that the electric current that bears is that the minimum resistance of single-circuit 2 times, monolithic is single-circuit 1/4th.
Claims (3)
1. a double loop resistive element is characterized in that, this resistive element two ends symmetry up and down has the even number Baltimore groove, and the spacing of the adjacent Baltimore groove of homonymy is identical, has rectangular channel in the middle of adjacent two pairs of Baltimore grooves.
