Description
Technical field
The utility model relates to high voltage electric equipment technical field, relates to high-voltage mutual inductor, specifically a kind of voltage transformer.
Background technology
The electricity that the power distribution network of current China uses high-voltage power metering box and proportioning device of high voltage electric energy to carry out between Utilities Electric Co. and large user is in a large number settled accounts.Two unearthed voltage transformers and two current transformers and a three-phase electric energy meter are adopted to form according to this kind equipment of requirement of DL448-2000 " electric power meter technical management code ".High-voltage power metering box also belongs to combined instrument transformer category, is generally used for open air; Accounting for most is indoor proportioning device of high voltage electric energy, uses after being connected each other with four high-voltage mutual inductors by copper bar.It is complicated that this just causes proportioning device of high voltage electric energy back panel wiring, the copper product that consumption rate is more.But high-tension fuse can be accessed in voltage transformer front end, so combined instrument transformer is also not suitable for using in proportioning device of high voltage electric energy according in the use habit proportioning device of high voltage electric energy of user.
Generally all be provided with fuse in voltage transformer, common fuse is all disposable, after exceeding setting a period of time, makes Melt molten, thus circuit is disconnected with the heat that himself produces according to electric current.Owing to just needing to take out the new fuse that changes the outfit in time after fuse use; When circuit be in be not very stable time, need user to change fuse continually, and frequently changing the outfit of fuse can cause the dislocation of instrument transformer internal electronic element, finally cause instrument transformer therefore to be scrapped.
Summary of the invention
The utility model is not enough for prior art, and provide a kind of voltage transformer, this voltage transformer can pass through self-recoverage fuse Reusability, reminds user's circuit malfunctions; This voltage transformer is exposed without copper bar simultaneously, compact conformation, easy-to-connect, security performance are good.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of voltage transformer, for totally-enclosed all insulation structure, comprise voltage device body, fuse room and base plate, a pour mass is become with poured with epoxy resin, in described voltage device body, a winding, secondary winding and iron core are fixed on described base plate after insulation encapsulation process, primary connection terminal and secondary wiring terminals form external coupling part, described fuse room comprises self-recoverage fuse, the fuse mounting groove of warning device and placement high-tension fuse, the sealing part of described fuse room is provided with can the capping of package fuse, described capping is connected by helicitic texture with described fuse mounting groove, described fuse mounting groove side sidewall is provided with transparent plexiglass block, described warning device comprises light-emitting diode, microcomputerized controller and alarm, described microcomputerized controller signal connects described alarm.
In technique scheme, preferably, the bottom of described fuse mounting groove is provided with spring shim, and described spring shim contacts with described self-recoverage fuse.
In technique scheme, preferably, be connected with can bear with the short circuit of a described winding the described self-recoverage fuse that electric current matches by wire between described winding the two poles of the earth.
In technique scheme, preferably, described secondary wiring terminals is connected by line with described secondary winding, and described pour mass is provided with installation inserts, and described voltage device body and described installation inserts are fixed on described base plate after the encapsulation process that insulate.
The utility model compared with prior art, has following beneficial effect: this voltage transformer of the utility model can pass through self-recoverage fuse Reusability, reminds user's circuit malfunctions; This voltage transformer is exposed without copper bar simultaneously, compact conformation, easy-to-connect, security performance are good.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment entirety.
Fig. 2 is the structural representation of the utility model embodiment warning device.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: see Fig. 1, Fig. 2, a kind of voltage transformer, for totally-enclosed all insulation structure, comprise voltage device body 1, fuse room 2 and base plate 3, a pour mass 4 is become with poured with epoxy resin, in described voltage device body 1, a winding, secondary winding and iron core are fixed on described base plate 3 after insulation encapsulation process, primary connection terminal and secondary wiring terminals form external coupling part, described fuse room 2 comprises self-recoverage fuse 21, the fuse mounting groove 22 of warning device 5 and placement high-tension fuse, the sealing part of described fuse room 2 is provided with can the capping 23 of package fuse, described capping 23 is connected by helicitic texture with described fuse mounting groove 22, install more convenient, cable plug need not be dismantled, described fuse mounting groove 22 side sidewall is provided with transparent plexiglass block, described warning device 5 comprises light-emitting diode 53, microcomputerized controller 51 and alarm 52, described microcomputerized controller 51 signal connects described alarm 52.
The bottom of described fuse mounting groove 22 is provided with spring shim 24, and described spring shim 24 contacts with described self-recoverage fuse 21.
Be connected with can bear with the short circuit of a described winding the described self-recoverage fuse 21 that electric current matches by wire between described winding the two poles of the earth.
Described secondary wiring terminals is connected by line with described secondary winding, described pour mass 4 is provided with and installs inserts 41, and described voltage device body 1 is fixed on described base plate 3 after the encapsulation process that insulate with described installation inserts 41.
During use, when voltage device body 1 occur overcurrent cause self-recoverage fuse 21 temporarily open circuit time, the electric current flow through with voltage device body 1 passes into warning device 5, and microcomputerized controller 51 connects alarm 52 and light-emitting diode 53 by the signal of telecommunication, alarm 52 starts to report to the police, and light-emitting diode 53 is luminous; After being repaired after overcurrent occurs voltage device body 1, electric current does not pass into warning device 5, and microcomputerized controller 51, alarm 52 and light-emitting diode 53 quit work.
If when self-recoverage fuse 21 is scrapped after repeatedly using, can to outward winding the capping 23 of fuse mounting groove 22, the self-recoverage fuse 21 now scrapped is ejected by spring shim 24, only needs to extract out the self-recoverage fuse 21 burnt and puts into and new can complete replacing very easily.
The utility model compared with prior art, has following beneficial effect: this voltage transformer of the utility model can pass through self-recoverage fuse Reusability, reminds user's circuit malfunctions; This voltage transformer is exposed without copper bar simultaneously, compact conformation, easy-to-connect, security performance are good.
