Abstract
The invention discloses a self-restoring type over/under-voltage protector, which comprises a box body (2) and a protector circuit (3). The protector circuit (3) is provided with a voltage value reading end. Improvements are as follows: the box body is only provided with three wiring terminals, one pair of wiring terminals comprise a live wire access end (5) and a live wire leading-out end (4), the protector circuit (3) is used for controlling disconnection or connection of the live wire access end (5) and the live wire leading-out end (4), the other wiring terminal is a zero wire access end (1), the zero wire access end (1) is connected with the voltage value reading end of the protector circuit (3), and the specifications of the zero wire access end (1) are the same as or lower than the specifications of the live wire access end (5) and the live wire leading-out end (4). Compared with the prior art, the self-restoring type over/under-voltage protector has a simple structure, the comprehensive cost of the protector can be reduced to a large extent, and the reliability of the protector can be improved to a large extent. Particularly, the size of the protector can be reduced to a large extent, and the size of a power distribution box can be reduced to a large extent when the protector is used in the power distribution box.
Description
Technical field
The present invention 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 has also 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 by this invention provides a kind of simple in structure, can reduce largely the protector integrated cost and improve the Self-recover overvoltage-undervoltage protector of protector reliability.
The objective of the invention is to realize 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 present invention is simple in structure, can reduce largely the protector integrated cost and improve the protector reliability, is used in simultaneously the volume that can reduce largely to rebuild distribution box in the distribution box.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1.
Fig. 2 is the structural representation that Fig. 1 looks up.
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 embodiment of the invention 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).
