Abstract
The utility model discloses a drop out fuse switch with position detection interface. The permanent magnet supported by an elastic support is arranged on a base below a movable fusing tube body of a fuse of the drop-out fuse switch, a reed switch support and a reed switch fixed by the reed switch support are fixed on a wiring terminal below a fixed supporting insulator, the reed switch and the permanent magnet correspond to form an auxiliary induction contact, and the reed switch forming the auxiliary induction contact is used as a position detection interface. The auxiliary induction contact composed of the permanent magnet and the reed switch is organically combined with the prior art, the reed switch is used as a detection interface, and the opening and closing position of the drop-out fuse switch is detected according to the working state of the reed switch, so that a reliable basis is provided for the automation of a power distribution network system. And has the advantages of novel conception, simple and compact structure, stable working performance, suitability for popularization and the like.
Description
Technical Field
The utility model relates to a high tension switchgear power supply unit, specifically say so, relate to the high tension switchgear power supply unit who uses for realizing the protection and the isolation of circuit segmentation and the fault point that opens and shuts in the distribution network system.
Background
In the current 10 kV power distribution network power supply system, a drop-out fuse switch is widely applied as a line section switch or a transformer primary side switch, and the protection and isolation of a fault point are realized by overcurrent fuse during power failure or accident of a line through manual pulling and closing operation. With the application of distribution network automation and the input of distributed photovoltaic power supplies in recent years, the corresponding switch is required to be provided with a position detection interface so as to realize a remote signaling function, and the original drop-out switch cannot meet the requirement of automation control because the original drop-out switch does not have the corresponding function.
Disclosure of Invention
An object of the utility model is to provide a drop out fuse switch with position detection interface, it can realize being surveyed the detection of switch position, satisfies above-mentioned distribution network system automated control's demand, remedies the not enough of prior art existence.
The technical scheme of the utility model as follows: the drop-out fuse switch comprises an existing drop-out fuse switch body, a permanent magnet supported by an elastic support is arranged on a base below a fuse movable fuse tube body of the drop-out fuse switch body, a reed tube support and a reed tube fixed by the reed tube support are fixed on a wiring terminal below a fixed supporting insulator, the reed tube and the permanent magnet correspond to form an auxiliary induction contact, and the reed tube forming the auxiliary induction contact is used as a position detection interface.
The utility model discloses a because the supplementary response contact that has taken permanent magnet and tongue tube to constitute combines with prior art organically, can regard as the detection interface by the tongue tube to the operating condition through the tongue tube detects drop out fuse switch's the position that opens and shuts of locating, and then provides reliable foundation for distribution network system automation. The invention has the advantages of novel conception, simple and compact structure, stable working performance, capability of meeting outdoor working environment, suitability for popularization and application and the like.

Fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description
The drop-out fuse switch with the position detection interface shown in fig. 1 reserves the existing drop-out fuse switch body 1, an elastic support 3 consisting of elastic metal reeds is arranged on a base below a fuse movable fuse tube body 2 of the drop-out fuse switch body 1, and a permanent magnet 4 is arranged on the elastic support 3; meanwhile, a reed switch bracket 5 is fixed on a wiring terminal below a fixed supporting insulator of the drop-out type fusing switch body 1, and a reed switch 6 is installed and fixed on the reed switch bracket 5; the reed switch 6 and the permanent magnet 4 are correspondingly formed into an auxiliary induction contact which is formed by combining the two in an induction mode.
When the fuse movable fusing tube body 2 is located at a switch-on position, the permanent magnet 4 is close to the reed switch (the electrical performance is kept), and under the action of the magnetic field of the permanent magnet 4, the reed switch in the reed switch 6 acts (the normally open contact closes/the normally closed contact opens); when the drop-out fuse switch is pulled open or the fuse movable fuse tube body 2 falls off under the fault condition, the fuse movable fuse tube body 2 drives the elastic support 3 and the permanent magnet 4 to be away from the reed switch 6 together, then the contact inside the reed switch resets and serves as an interface to send out signals, and therefore position state detection of the switch is achieved.
The utility model discloses except possessing outdoor drop out fusing switch position and detecting and providing functions such as telesignalling interface, its supplementary response contact is installed in drop out fusing switch body 1 and uses with other measuring and control device equipotential with non-fully insulating mode to solved the insulating problem on the high-tension apparatus, this utility model establishes the due positive role of performance for advancing distribution network automation system.
