Description
Technical field
The utility model relates to a kind of electric power system high-tension measurement equipment, relates in particular to a kind of epoxy resins insulation single-phase zone elbow head dummy socket double fuse voltage transformer.
Background technology
Voltage transformer is that the high voltage with primary system converts in proportion that normalized low-voltage supplies that electrical secondary system is measured into, protection and automatically control use; Therefore; Voltage transformer is when utilization and operation, and its primary connection terminal must be electrically connected with the primary system high voltage bus.But traditional primary connection terminal is the exposed output of copper bar, and needs between cabinet to guarantee the electric clearance greater than regulation, and it is big to take up room during use, and wiring is inconvenient, and gets an electric shock easily, also causes easily the dizzy phenomenon of arc lightning to take place between phase and phase and poor stability.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of does not have that copper bar is exposed, compact conformation, easy-to-connect, band elbow head dummy socket double fuse voltage transformer that security performance is good.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
A kind of band elbow of the utility model head dummy socket double fuse voltage transformer is totally-enclosed all insulation structure, mainly is made up of voltage device body, elbow head dummy cable socket, fuse chamber and base plate, becomes a pour mass with poured with epoxy resin; In voltage device body, one time winding, secondary winding and iron core are fixed on the base plate after the insulation encapsulation process; Primary connection terminal and secondary connection terminal constitute external coupling part, primary connection terminal the two poles of the earth be structure identical can with the matching used elbow head dummy of cable plug cable socket;
Described elbow head dummy cable socket is located at pour mass top and is electrically connected with fuse, above elbow head dummy cable socket inner conductive body, arc-control device is housed;
Be connected with and can bear the fuse that electric current is complementary with the short circuit of a winding through lead between described winding the two poles of the earth, a described winding has two fuse protections;
It is indoor that described fuse is arranged at epoxy resin enclosed fuse, and described fuse chamber has two, be located at the both sides, top of voltage device body respectively, but the sealing part in the fuse chamber is provided with the plug of package fuse;
Described pour mass is provided with the secondary connection terminal and inserts is installed.
Compared with prior art, the utility model has the advantages that:
1. safe in utilization.Primary connection terminal the two poles of the earth of the utility model are elbow head dummy cable socket form, have changed traditional primary connection terminal and be the exposed way of output of copper bar, and the generation of the phenomenon that can effectively prevent to get an electric shock has improved the security performance of power supply greatly.
2. compact overall structure has reduced usage space.Primary connection terminal the two poles of the earth of the utility model are elbow head dummy cable socket form, after pegging graft with cable plug, need not leave electric clearance to cabinet, make compact overall structure, dwindle overall dimensions.
3. can effectively avoid burning the phenomenon of voltage transformer because of overvoltage, overload.A winding of the utility model has the protection of two fuses, can effectively prevent overvoltage to occur or the secondary overload causes that voltage transformer burns phenomenon at electrical network, improves the reliability of power supply greatly.
Below in conjunction with accompanying drawing the utility model is further described:
