Abstract
The utility model discloses a kind of embedded secondary fuse devices of mutual inductor, including secondary terminal box, secondary terminals, fuse slot and protecting cap；The end face of secondary terminal box is embedded with secondary terminals, fuse slot, fuse is provided in fuse slot, one end of fuse is connected with protecting cap, and protecting cap is connect by enameled wire with secondary terminals, the other end of fuse is connected with spring, and spring is connect by mutual inductor secondary lead wire with iron core.The utility model has the beneficial effects that effectively saving the time of installation secondary fuse device；Effectively increase the wiring space at secondary terminal box；Avoid installation secondary fuse device, the damage of mutual inductor and fuse caused by winding displacement mistake.
Description
Technical field
The utility model relates to secondary fuse engineering device technique field more particularly to a kind of embedded secondary fuse dresses of mutual inductor
It sets.
Background technique
Voltage transformer (PT) also has abbreviation TV and YH, it is that measuring instrumentss in electric system, relay protection etc. are secondary
The sensor of equipment acquisition electrical primary loop voltage information.
High voltage is converted into low-voltage, i.e. 100V, 220V by PT in proportion, and PT is once flanked in primary system, secondary side
Connect measuring instrumentss, relay protection etc..
Voltage transformer secondary safety device, main function are to prevent voltage transformer secondary electric current excessive, by fuse, are protected
The composition such as dangerous seat, lead.Voltage transformer secondary safety device greatly avoids the phenomenon that mutual inductor is burnt because of wiring reason.
Existing secondary fuse device is that circumscribed is to be connected to Insurance Block by two leads to be connected on mutual inductor secondary terminals.It is single such
Have following several drawbacks:
1, very inconvenient when circumscribed secondary fuse device client installs, it is needed at Secondary Connections of PTs terminal more
Secondary wiring.
2, circumscribed secondary fuse device Insurance Block volume is larger, influences Secondary Connections of PTs space.
If 3, circumscribed secondary fuse device winding displacement position is bad, it will cause voltage transformer secondary short circuit and burn mutual inductor
Or safety device.
Utility model content
The utility model is to solve time-consuming and laborious, safety device winding displacement mistake of traditional circumscribed safety device wiring etc. to ask
Topic, provides a kind of embedded secondary fuse device of mutual inductor.
In order to solve the above technical problems, the technical solution of the utility model is: the embedded secondary fuse device of mutual inductor, packet
Include secondary terminal box, secondary terminals, fuse slot and protecting cap；The end face of secondary terminal box is embedded with secondary terminals, fuse slot, melts
It is provided with fuse in silk slot, one end of fuse is connected with protecting cap, and protecting cap is connect by enameled wire with secondary terminals, fuse
The other end be connected with spring, spring is connect by mutual inductor secondary lead wire with iron core.
Further, secondary terminals are located at the lower section of fuse slot.
The utility model has the beneficial effects that
1, the time of installation secondary fuse device is effectively saved.
2, the wiring space at secondary terminal box is effectively increased.
3, installation secondary fuse device, the damage of mutual inductor and fuse caused by winding displacement mistake are avoided.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model application schematic diagram one；
Fig. 3 is the utility model application schematic diagram two.
Wherein: 1- secondary terminal box, 2- enameled wire, 3- iron core, 4- secondary terminals, 5- fuse slot, 6- mutual inductor is secondary to be drawn
Line, 7- spring, 8- fuse, 9- protecting cap.
Specific embodiment
1-3 is described further specific embodiment of the present utility model with reference to the accompanying drawing.
The embedded secondary fuse device of mutual inductor, including secondary terminal box 1, secondary terminals 4, fuse slot 5 and protecting cap 9；
The end face of secondary terminal box 1 is embedded with secondary terminals 4, fuse slot 5, and secondary terminals 4 are located at the lower section of fuse slot 5, in fuse slot 5
It is provided with fuse 8, one end of fuse 8 is connected with protecting cap 9, and protecting cap 9 is connect by enameled wire 2 with secondary terminals 4, fuse
8 other end is connected with spring 7, and spring 7 is connect by mutual inductor secondary lead wire 6 with iron core 3.
More than, the only preferable specific embodiment of the utility model, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art is in the technical scope that the utility model discloses, according to the utility model
Technical solution and its utility model design be subject to equivalent substitution or change, should all cover the protection scope of the utility model it
It is interior.
