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 of shockproof.
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.
Always just in vibration when instrument transformer runs, because magnetic force factor: its vibration be reduced, mainly reduce resonance, because this resonance body is difficult to reduce.Due to vibration, cause the fuse in instrument transformer to be subjected to displacement, depart from the metallic gasket originally contacted and cause open circuit, so the shockproof difficult problem becoming many engineers and need to solve of instrument transformer.
Summary of the invention
The utility model is not enough for prior art, a kind of voltage transformer of shockproof is provided, the voltage transformer of this shockproof can make fuse and spring shim keep in touch by Spring screws always, thus preventing the generation of open circuit, the voltage transformer of this shockproof 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 of shockproof, 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 voltage device body, a winding, secondary winding and iron core are fixed on base plate after insulation encapsulation process, primary connection terminal and secondary wiring terminals form external coupling part, described fuse room comprises high-tension fuse and places the fuse mounting groove of 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 fuse mounting groove, described fuse mounting groove inwall is provided with at least three spring mountings, described spring mountings is arranged around the axis of described fuse mounting groove, described spring mountings comprises Spring screws and pad, described pad is fixed on the spring terminal of described Spring screws, described fuse mounting groove outer wall is provided with the screw hole with described spring mountings equal number.
In technique scheme, preferably, the bottom of described fuse mounting groove is provided with spring shim, and described spring shim contacts with described high-tension fuse.
In technique scheme, preferably, be connected with can bear with the short circuit of a described winding the described high-tension 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, there is following beneficial effect: the voltage transformer of this shockproof of the utility model can make fuse and spring shim keep in touch by Spring screws always, thus preventing the generation of open circuit, the voltage transformer of this shockproof 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.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: see Fig. 1, a kind of voltage transformer of shockproof, 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 voltage device body 1, a winding, secondary winding and iron core are fixed on base plate 3 after insulation encapsulation process, primary connection terminal and secondary wiring terminals form external coupling part, it is characterized in that: described fuse room 2 comprises high-tension fuse 21 and places the fuse mounting groove 22 of 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 inwall is provided with at least three spring mountings, described spring mountings is arranged around the axis of described fuse mounting groove 22, described spring mountings comprises Spring screws 51 and pad 52, described pad 52 is fixed on the spring terminal of described Spring screws 51, described fuse mounting groove 22 outer wall is provided with the screw hole with described spring mountings equal number.
The bottom of described fuse mounting groove 22 is provided with spring shim 24, and described spring shim 24 contacts with described high-tension fuse 21.
Be connected with can bear with the short circuit of a described winding the described high-tension 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.
