Abstract
The utility model discloses a self-reclosing overvoltage undervoltage protector comprising a box body (2) and a protector circuit (3). The protector circuit (3) is provided with a voltage valuing end. The utility model is characterized in that three binding posts are disposed on the box body, and a pair of the above mentioned three binding posts are respectively a live wire leading-in end (5) and a live wire leading-out end (4); the protector circuit (3) can be used to control the switching on/off of the live wire leading-in end (5) and the live wire leading-out end (4); the other binding post is a zero line leading-in end (1), which is connected with the voltage valuing end of the protector circuit (3); the specification of the zero line leading-in end (1) is equal to or lower than that of the live wire leading-in end (5) and the live wire leading-out end (4). Compared to the prior art, the self-reclosing overvoltage undervoltage protector is advantageous in that the structure is simple, the comprehensive costs of the protector can be reduced to a relatively large extent, the reliability of the protector can be improved, and especially the size of the protector can be reduced to a relatively large extent, in addition, when the protector is used in a distribution box, the size of the distribution box can be renovated and reduced to a relatively large extent.
Description
Technical field
The utility model relates to a kind of circuit brake, particularly a kind of Self-recover overvoltage-undervoltage protector.
Background technology
Present circuit brake; Self-recover overvoltage-undervoltage protector particularly; comprise box body and protector circuit; on box body, generally be provided with 4 binding posts; wherein pair of terminals is sub; it generally is live wire; be provided with the overvoltage-undervoltage protector circuit between this pair of wire connection terminals, and another pair of wire connection terminals generally is zero line; only be to pass through box body; simultaneously the protector circuit is connected with zero line by wire and reads magnitude of voltage, and when magnitude of voltage off-rating scope, the protector circuit then disconnects live wire; in the time of in magnitude of voltage returns to the rated value scope, the protector circuit is then connected live wire.
The defective of above-mentioned protector is in the following areas: the one, used 4 binding posts; complex structure; increased the manufacturing cost of protector; the 2nd, binding post is many; must cause the raising of failure rate; the 3rd is that 4 binding posts generally all must use identical specification and specification requirement; such as load current value etc.; also so that the manufacturing cost increase; four fundamental rules are the increases of making volume; when particularly a plurality of protectors are installed in the power distribution cabinet side by side, must cause the increase of whole power distribution cabinet volume.
Therefore, a kind of simple in structure, the Self-recover overvoltage-undervoltage protector that can reduce largely the protector integrated cost and improve the protector reliability just is suggested.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, can reduce largely the protector integrated cost and improve the protector reliability, particularly can reduce largely the Self-recover overvoltage-undervoltage protector of the volume of protector.
The purpose of this utility model realizes by following structure: comprise box body (2) and protector circuit (3); protector circuit (3) is provided with voltage value end; its improvement is: only be provided with 3 binding posts on box body; wherein pair of terminals is live wire incoming end (5) and live wire exit (4); disconnection between protector circuit (3) control live wire incoming end (5) and the live wire exit (4) or be communicated with; another binding post then is zero line incoming end (1); zero line incoming end (1) is connected with the voltage value end of protector circuit (3), and the specification of zero line incoming end (1) is equal to or less than live wire incoming end (5) and live wire exit (4).
As preferred technical scheme, the specification of above-mentioned zero line incoming end (1) is preferably lower than live wire incoming end (5) and live wire exit (4).
Compared with prior art; the utility model is simple in structure; can reduce largely the protector integrated cost and improve the protector reliability, particularly can reduce largely the volume of protector, be used in the volume that then can reduce largely to rebuild distribution box in the distribution box.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of looking up of Fig. 1.
Shown in the figure: 1 is the zero line incoming end, and 2 is box body, and 3 is the protector circuit, and 4 is the live wire exit, and 5 is the live wire incoming end.
Embodiment
Embodiment 1: with reference to accompanying drawing 1～2; structural representation for the utility model embodiment 1; comprise box body 2 and protector circuit 3; protector circuit 3 is provided with voltage value end; be provided with 3 binding posts at box body; wherein pair of terminals is live wire incoming end 5 and live wire exit 4; design specification is 220V20A; disconnection between protector circuit 3 control live wire incoming ends 5 and the live wire exit 4 or be communicated with; another binding post then is zero line incoming end 1; zero line incoming end 1 is connected with the voltage value end of protector circuit 3; and the specification of zero line incoming end 1 is lower than live wire incoming end 5 and live wire exit 4; the design specification of zero line incoming end 1 is 220V0.5A, and the thickness of box body 2 then can be less than 27mm.
Embodiment 2: compare with embodiment 1, the difference of present embodiment is: the specification of described zero line incoming end 1 is identical with live wire exit 4 specifications with live wire incoming end 5, and design specification is 220V16A.
Claims (2)
1. Self-recover overvoltage-undervoltage protector; comprise box body (2) and protector circuit (3); protector circuit (3) is provided with voltage value end; it is characterized in that: on box body, only be provided with 3 binding posts; wherein pair of terminals is live wire incoming end (5) and live wire exit (4); disconnection between protector circuit (3) control live wire incoming end (5) and the live wire exit (4) or be communicated with; another binding post then is zero line incoming end (1); zero line incoming end (1) is connected with the voltage value end of protector circuit (3), and the specification of zero line incoming end (1) is equal to or less than live wire incoming end (5) and live wire exit (4).
