Description
Technical field
The present invention relates to a kind of device being used to indicate fuse operating mode, relate to a kind of sensitive switch warning device on fuse especially.
Background technology
Fuse refers to when electric current exceedes setting; with the heat that itself produces, melt is fused; a kind of electrical equipment of open circuit; fuse is widely used in high and low voltage electric distribution system and control system and power consumption equipment; as the protector of short circuit and overcurrent, be apply one of the most general protector.
Usually, people to be fitted or upspring the disjunction being separated and judging fused mass of fuse by shell fragment that fuse is arranged and fuse corresponding contact face, and whether circuit occurs exception.This kind judges the simple and convenient and successful of the mode of fuse blows body disjunction by the location status of visual shell fragment and contact-making surface, is those skilled in the art's extensive use.
But; along with the fast development of modern power systems; supervisory computer control system is widely used; high-performance, intelligentized requirement are proposed to low-voltage electrical apparatus supporting with it; and require that product has the functions such as protection, monitoring, test, self diagnosis, display; especially widely used fuse is had higher requirement, and in prior art, judged by the Visual Observations Observations of people that the mode of the disjunction of fuse has not obviously met the intelligentized requirement of modern power industry system to fuse.
For this reason, Chinese patent literature CN201435368Y discloses fusing alarm for fuse, this fuse alarm, comprise a underframe, described underframe is provided with sensitive switch and L shape lever, and described sensitive switch is provided with the button of control switch circuit opening and closing, lever corner and underframe hinged, the button contacts of described lever one end and sensitive switch, the other end associates with the fusing of fuse.Lever and fuse blows action associated end are provided with push rod, and push rod end is provided with push rod face, and underframe is provided with a thickening part, and thickening part forms the bearing-surface of one and joint, lever side, and side, thickening part forms a groove, is provided with an elastic limit product in groove.The prior art by sensitive switch and L shape lever be arranged so that the fusing of fuse blows body after make L-type lever action, L-type lever triggers sensitive switch, achieves the intelligentized requirement of fuse.
But still there is following problem in actual use in this fusing alarm for fuse:
1. this alarm is in order to fixing sensitive switch and L shape lever, a underframe is provided with below sensitive switch and L shape lever, and by tapping screw, lever and underframe are connected to one piece, by screw, sensitive switch is fixed on underframe, further, rotating to limit L-type lever, this alarm also being arranged on underframe the thickening part supporting L-type lever, the complex structure being arranged so that this alarm of underframe and thickening part, production cost improves; 2. in the prior art, L shape lever and sensitive switch are that open type is arranged, and L shape lever and sensitive switch are easily subject to the effect of external force in the course of the work and loosening even come off, and reduce the reliability of alarm; 3. in the prior art, it is comparatively large that the set-up mode of L shape lever and sensitive switch open type makes this alarm take up room, and for the fuse that installing space is originally limited, increases the prior art and be arranged on difficulty on fuse.
Summary of the invention
For this reason, technical problem to be solved by this invention is to overcome fusing alarm for fuse complex structure in prior art, functional reliability is poor, with fuse, the problem of difficulty is installed, there is provided a kind of structure simple, make full use of the design feature of fuse own, reliable operation and take up space little, with fuse, the sensitive switch warning device simply and easily on fuse is installed.
For solving the problems of the technologies described above, the present invention is a kind of sensitive switch warning device on fuse, comprise sensitive switch and power transmission lever, the compression shell fragment described fuse being provided with the connect-disconnect plug for loading and unloading fuse-link and indicating fuse-link whether to fuse, the housing of described sensitive switch offers the pressure interface being suitable for described connect-disconnect plug grafting, described connect-disconnect plug inserts the connection realizing described fuse and described sensitive switch in described pressure interface; Described power transmission lever one end is crimped on described compression shell fragment, and the other end stretches in described sensitive switch, controls described sensitive switch and send cut-off signals under the effect of the thrust that described power transmission lever is upspring at described compression shell fragment.
The present invention also comprises pressure interface locking device, it comprises, the pressure be vertically installed in described sensitive switch housing takes part in handle, described pressure is taken part in below handle and is arranged Compress Spring, described Compress Spring one end connects described pressure and takes part in handle, and the other end connects bottom described sensitive switch, and described pressure is taken part in handle and formed socket in the position of the described pressure interface of correspondence, when described pressure intervention handle presses down described compression bullet, described socket and described pressure interface aligned in position are suitable for described connect-disconnect plug and insert.
The housing of described sensitive switch forms the limiting section that restriction described power transmission lever rotates.
Described power transmission lever is stretched into by the opening taken shape on described sensitive switch housing, and the lower side of described opening forms described limiting section.
Described power transmission lever is rotated by the pivot point be arranged in described sensitive switch, and described power transmission lever is crimped on the one end on described compression shell fragment to the distance of described pivot point and is greater than described power transmission lever and puts in the distance of the one end in described sensitive switch to described pivot point.
Described power transmission lever one end rotates around described pivot point by described compression shell fragment thrust of upspringing, and the other end touches the normally opened contact conducting that described sensitive switch makes described sensitive switch, and normally-closed contact transfers disconnection to.
Be provided with bolster between the two side of described sensitive switch housing, described power transmission lever forms the hole being suitable for described bolster and inserting, described bolster coordinates with described hole and forms described pivot point.
