Abstract

The utility model discloses an 18mm-wide double-line electric leakage circuit breaker with high breaking capacity, comprising a casing, a handle operating member, a motion mechanism, an arc striking/extinguishing system, an electromagnetic release, an electronic circuit board for electric leakage and a bimetal. The double-line electric leakage circuit breaker has the advantage that: by using the circuit breaker, the effective space of an arc extinguish chamber at N pole is enlarged, as a result, the N pole is provided with a large arc extinguish chamber and arc spark generated by on-off of the circuit breaker can be extinguished timely and rapidly, so the breaking capacity of the circuit breaker is effectually enhanced. Every group of moving contacts, fixed contacts and run-on tabs is equipped with an arc extinguish chamber with different arrangement direction, and the two arc extinguish chambers have the same size and large volume.

Description

A kind of wide 18 millimeters two-wire residual current circuit breaker with high breaking capacity
Technical field
The utility model relates to a kind of two-wire residual current circuit breaker, and particularly a kind of have onesize two arc control device and bulky 18 millimeters two-wire residual current circuit breaker simultaneously.
Background technology
As shown in Figure 1, the two-wire circuit breaker volume inside of existing 18 millimeters width is very little, and the other end of the L utmost point run-on tab 1 of L utmost point arc control device 4 lower ends links to each other with the bottom of bimetal leaf 2, and brace 3 links together with bimetal leaf 2, brace 3 is recessed down, the space of (the N utmost point) below having taken is so N utmost point arc control device are just very little, L utmost point arc control device and N utmost point arc control device vary in size like this, and the size of two arc control device is all smaller, so just causes arc quenching effect bad, and breaking capacity is poor.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of two arc control device sizes identical and bulky 18 millimeters two-wire residual current circuit breaker with high breaking capacity
To achieve these goals, technical solution adopted in the utility model is: a kind of 18 millimeters two-wire residual current circuit breaker with high breaking capacity, comprise that housing, lever operated, actuating mechanism, arc leading and suppressing system, magnetictrip, electric leakage action are with electronic circuit board and bimetal leaf
The circuit breaker L utmost point and the N utmost point are equipped with arc control device, and two arc control device placement directions become angle, and two arc control device size is identical or suitable; L utmost point run-on tab one end is positioned at L utmost point arc control device bottom, the other end links to each other with the lower end of bimetal leaf, the another side of the lower end of bimetal leaf is welded in the brace lower end, and the upper end of brace is fixed and is welded on the junction block, and the upper right side of L utmost point arc control device is provided with one group of dynamic and static contact; Be provided with one group of dynamic and static contact directly over the N utmost point arc control device, positive the right is provided with N utmost point run-on tab.
Angle between the described two arc control device placement directions is the right angle.
The beneficial effects of the utility model: after adopting this patent, cause the N utmost point arc control device useful space to increase, thereby make the N utmost point also be provided with big arc control device, the arc spark that causes the circuit breaker break-make to produce can in time extinguish rapidly, effectively improves the breaking capacity of circuit breaker.Every group of dynamic and static contact, run-on tab all are furnished with the arc control device that placement direction is different, and two arc control device are onesize and volume is big.
Description of drawings
The front view of Fig. 1, existing 18 millimeters two-wire residual current circuit breaker (lid removes the back);
Fig. 2, front view of the present utility model (lid removes the back);
Fig. 3, rear view of the present utility model (lid removes the back).
Embodiment
As Fig. 2, shown in Figure 3, have 18 millimeters two-wire residual current circuit breaker of high breaking capacity, comprise that housing, lever operated, actuating mechanism, arc leading and suppressing system, magnetictrip, magnetictrip have short circuit holding function and electric leakage holding function simultaneously.Electric leakage action is with electronic circuit board 7 and bimetal leaf 2, and the circuit breaker L utmost point and the N utmost point are equipped with arc control device (L utmost point arc control device 4 and N utmost point arc control device 41), and two arc control device placement directions become angle (being preferably the right angle), and two arc control device size is identical or suitable;
L utmost point run-on tab 1 one ends are positioned at L utmost point arc control device 4 bottoms, the other end links to each other with the lower end of bimetal leaf 2, the another side of the lower end of bimetal leaf 2 is welded in brace 3 lower ends, and the upper end of brace 3 is fixed and is welded on the junction block 5, and the upper right side of L utmost point arc control device is provided with one group of dynamic and static contact 6; Above-mentioned syndeton, for N utmost point arc control device have been vacateed enough spaces, thus the same size of N utmost point arc control device with L utmost point arc control device, and whole volume is big, and the two poles of the earth arc extinguishing and disjunction effect are all good.
Be provided with one group of dynamic and static contact 61 directly over the N utmost point arc control device, positive the right is provided with N utmost point run-on tab 11.Two arc control device have onesize and volume big, the direction difference is separately towards corresponding contact; Pull bar is between two moving contacts, and it moves than city's field circuit breaker pull bar dexterity.
