Abstract

The utility model discloses a mechanical split-combined indication device of a circuit breaker. In the technical proposal, a right-angle bent plate is added between a swing plate and a rotating shaft; one end of the right-angle bent plate is fixedly connected with the rotating shaft; the other end of the right-angle bent plate rotates around a hinge shaft through shifting the swing plate by a shifting rod; and the hinge shaft is fixedly arranged on a side plate of a circuit breaker. Because the distance between the hinge shaft and the shifting rod is far less than the distance between the hinge shaft and a mark plate, when the rotating shaft rotates for 5 degrees, the right-angle bent plate also rotates for 5 degrees correspondingly; the rotating angle of the swing plate is amplified to be more than 20 degrees thereafter; the rotating amplitude of the mark plate is increased to above 40 mm from the original 12 mm; and the 'split' and 'combined' position states can be clearly displayed through the observation window.

Description

Circuit breaker mechanical type deciliter indicating device

Technical field

The utility model relates to a kind of mine anti-explosion electric equipment, is specifically related to 400A, 500A, the mechanical type that uses on the circuit breakers such as 630A deciliter indicating device.

Background technology

Requirement according to People's Republic of China's " flame-proof mine low-voltage alternating-current vacuum feed switch " industry standard, the closure of feeding switch and open position, clear reliable indicating device should be arranged, and the closure of feeding switch and open position, just circuit breaker close the branch position, therefore just require circuit breaker that clear reliable indicating device should be arranged.

At present, domestic existing circuit breaker machinery closes the branch indicating device, with the 400A circuit breaker is example: when its electromagnet is switched on or switched off power supply, armature drives the oscillating deck rotation and makes the closed or disconnection of vacuum tube, follow rotating certain angle with the rotating shaft of oscillating deck one, the corner of calculating rotating shaft according to pendulum arm length and stroke counter is 5 degree, therefore the angle of fork swing also is 5 degree, the amplitude of fluctuation that is reacted to label just has only 12 millimeters, the centre-to-centre spacing of therefore " closing " " branch " two words also is 12 millimeters, cause can't distinguishing outside observation window the branch state that closes of circuit breaker like this, this covering device performs practically no function at all, does not play any substantial effect.

Summary of the invention

In order to solve the problems of the technologies described above, the utility model provides a kind of circuit breaker mechanical type deciliter indicating device, between pendulum plate and rotating shaft, increase angle block of right angle is set, angle block of right angle one end and rotating shaft are fixed, the other end is stirred the pendulum plate by poke rod and is rotated around jointed shaft, and jointed shaft is fixed on the circuit breaker side plate.Since the distance between jointed shaft and the poke rod much smaller than and label between distance, when the same rotation of rotating shaft 5 degree angles, angle block of right angle rotates 5 degree thereupon, be reacted on the pendulum plate, pendulum plate rotational angle is amplified to more than 20 degree, the rotation amplitude of label is amplified to more than the 40mm by original 12mm, just can clearly demonstrate the location status of " branch ", " closing " two words by observation window.

The utility model is achieved by the following technical solution: a kind of circuit breaker is with mechanical type deciliter indicating device, the pendulum plate that comprise rotating shaft, is connected with rotating shaft, is installed in the label put on the plate, is arranged on label the place ahead and is installed in observation window on the case for circuit breaker; It is characterized in that: between described pendulum plate and rotating shaft, angle block of right angle is set; Described angle block of right angle one end is connected with rotating shaft, and the other end is connected with pendulum plate bottom by poke rod; Described pendulum plate middle and lower part is hinged by jointed shaft and circuit breaker side plate.

Described angle block of right angle, its horizontal sides is fixed by the cylinder of fixed mount and rotating shaft, and the vertical edges bottom is fixed by the end of connecting axle and rotating shaft; The vertical edges upper vertical is poke rod fixedly; Described poke rod sliding fit is inserted in the slotted hole of described pendulum plate bottom, and moves to string with nut, pad restriction swing plate shaft.

The junction of described angle block of right angle and poke rod makes slotted hole, and poke rod is inserted in the slotted hole, and with nut, spacers.

Good effect of the present utility model is:

1, do not changing the original structure of circuit breaker, only need set up angle block of right angle, the commentaries on classics width of cloth amplification several times of fork.Simple in structure, compactness is convenient to original circuit breaker display unit is transformed, and improvement cost is low.

2, because label changes width of cloth expansion, and " branch " " closes " two fonts and can amplify, from observation window, can clearly show, improve the safe application performance of circuit breaker.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the utility model structural representation;

Among the figure: 1, rotating shaft, 2, fixed mount, 3, angle block of right angle, 3-1, slotted hole, 4, connecting axle, 5, poke rod, 6, jointed shaft, 7, the circuit breaker side plate, 8, the pendulum plate, 9, label, 10, observation window, 11, case for circuit breaker.

Embodiment

As Fig. 1, Fig. 2, shown in Figure 3: a kind of circuit breaker is with mechanical type deciliter indicating device, comprises rotating shaft 1, the pendulum plate 8 that is connected with rotating shaft 1, is installed in the label 9 put on the plate 8, is arranged on the place ahead of label 9 and is installed in observation window 10 on the case for circuit breaker 11.It is characterized in that: between described pendulum plate 8 and rotating shaft 1, angle block of right angle 3 is set; Described angle block of right angle 3 one ends are connected with rotating shaft 1, and the other end is connected with pendulum plate 8 bottoms by poke rod 5; Described pendulum plate 8 middle and lower parts are hinged by jointed shaft 6 and circuit breaker side plate 7.

Described angle block of right angle 3, its horizontal sides is fixed by the fixed mount 2 and the cylinder of rotating shaft 1; The vertical edges bottom is fixed by the connecting axle 4 and the end of rotating shaft 1.Two limits of angle block of right angle 3 all are connected with rotating shaft, not only are connected firmly, and also increase the intensity of angle block of right angle 3, improve reliability.Angle block of right angle 3 vertical edges upper vertical are poke rod 5 fixedly, and poke rod 5 sliding fits are inserted in the slotted hole of pendulum plate 8 bottoms, and puts plate 8 axial motions with nut, pad restriction.

The junction of described angle block of right angle 3 and poke rod 5 makes slotted hole 3-1, and poke rod 5 is inserted among the slotted hole 3-1, and with nut, spacers.Slotted hole 3-1 is used to regulate the position of poke rod 5, both can adjust the pendulum angle of pendulum plate 8 easily, can also revise the swing position error of label 9, makes indicated number more accurate.

As shown in Figure 3: raise 2mm when poke rod 5 positions, the pendulum angle of putting plate 8 just can increase by 3 degree, is reflected to label 9, and its rotation amplitude increases 12mm.Because label 9 changes the width of cloth and enlarges, " branch " " closes " two fonts and can amplify, and can clearly show from observation window, improves the safe application performance of circuit breaker.
