Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the primary instruction operating diagram of the utility model；
Fig. 3 is the secondary instruction operating diagram of the utility model.
Specific embodiment
It is described in conjunction with the embodiments specific embodiment of the present utility model.
As shown in Figure 1, the switch-on/off indicator of electric leakage reclosure breaker, including indicating arm, indicating arm installation
On-board the circuit breaker on lid 3, offer through hole in breaker upper cover 3, indicating arm upper end it is vertical through through hole, top is from breaker
Expose in upper cover 3；
The indicating arm includes outer loop bar 9 and internal core rod 1, and the outer loop bar 9 passes through the through hole of breaker upper cover 3,
And it can move up and down in through hole；The outer wall of the outer loop bar 9 is provided with the baffle ring 2 of annular；
3 inner wall of breaker upper cover is also equipped with vertical slide bar 11, and lantern ring 10, institute are cased on the slide bar 11
The lantern ring 10 stated is fixedly connected with the baffle ring 2 of outer 9 bottom of loop bar, and limited screw 12 is additionally provided on slide bar 11, lantern ring 10 is carried out
/V；
The outer loop bar 9 is hollow structure, and the internal core rod 1 is mounted on outer 9 center of loop bar, and internal core rod 1 is in housing
It can be slided up and down in bar 9；The lower end position of the outer loop bar 9 is higher than the lower end position of internal core rod 1；
1 lower end of internal core rod is connected with idler wheel 13, and 5 upper surface of contact of breaker is also vertical to be provided with directly
The triangular plate 14 of angle triangle, upward, an acute angle direction contact of breaker 5 is hinged the bevel edge 4 of triangular plate 14 with contact base
Place；The idler wheel 13 is mounted on the bevel edge 4 of triangular plate 14.
9 lower end of outer loop bar is connected with extension feeler lever 8.
Described 14 1 right-angle sides of triangular plate are mounted on 5 upper surface of contact of breaker, another right-angle side is connected with card
Block, 3 inner wall of breaker upper cover are provided with rod 15, when the contact of breaker 5 is touched on circuit breaker base 7
During breaker pile crown 6, the fixture block of the triangular plate 14 is stuck in 15 upper surface of rod, and rod 15 limits 14 downlink of triangular plate
Position.
Indicating arm sets outer loop bar 9 and internal core rod 1, as two-stage indicative function, including primary instruction and secondary instruction.Just
Grade instruction, indicates for of short duration gate-dividing state.As shown in Fig. 2, contact of breaker 5 is lifted and departed from circuit breaker base 7
Breaker pile crown 6；When the angle that contact of breaker 5 lifts is smaller, internal core rod 1 is jacked up into prominent lid 3 on-board the circuit breaker
On.The purpose for setting triangular plate 14 is to increase the stroke of internal core rod 1, because 1 lower end of internal core rod is vertical movement, and is broken
During road device contact 5 lifts, idler wheel 13 is gradually to be moved along bevel edge 4 to the acute angle direction of 14 the top of triangular plate, i.e.,
The distance between idler wheel and contact of breaker 5 are increased, therefore the stroke of internal core rod 1 is than contact of breaker 5 here
Stroke is big.When 5 downlink of contact of breaker touches the breaker pile crown 6 on circuit breaker base 7, internal core rod 1 itself
Under gravity, 5 downlink of contact of breaker is followed.
Secondary instruction, indicates for prolonged or larger safety coefficient gate-dividing state.As shown in figure 3, when open circuit
When lifting angle and further become larger of device contact 5, the bevel edge 4 of triangular plate 14 touch extension feeler lever 8, by outer loop bar 9 and interior
Core bar 1 all jacks up, and outer 9 top of loop bar is also exposed on lid 3 on-board the circuit breaker.When 5 downlink of contact of breaker touches breaker bottom
Seat 7 on breaker pile crown 6 when, internal core rod 1 and outer loop bar 9 follow 5 downlink of contact of breaker under the gravity of itself.
Outer 9 downward storke of loop bar is limited by limited screw 12.The downward storke of outer loop bar 9 and triangular plate 14 is all limited, be in order to
It prevents that weight is excessive, influences contact of breaker 5 and breaker pile crown 6.
