Description
Technical field
The utility model is related to transformer technical field, more particularly, to a kind of voltage transformer winding protection device.
Background technology
Voltage transformer in use, protection device is added in primary side in the prior art, and protection device is complicated,
Control device high cost, while without protection device is added in Secondary Winding, the normal voltage caused by wiring error in use
Transformer Secondary Winding overcurrent or short circuit, cause voltage transformer to burn even blast, cause personnel to injure the damage with equipment
It is bad, fuse is set in Secondary Winding in existing technology and is protected, but the later stage can not recover, it is necessary to artificial operation recovery
To normal condition.
Utility model content
The purpose of this utility model is to provide a kind of voltage transformer winding protection device, and simple structure low cost can
Voltage transformer and equipment are effectively protected, while can be with self- recoverage to normal condition, it is not necessary to manual reversion.
To achieve the above object, the utility model is mutual there is provided a kind of voltage transformer winding protection device, including voltage
Sensor, the voltage transformer includes first winding, iron core and Secondary Winding, also neutral including being series at the first winding
Protection circuit between point and ground and the protection element of Secondary Winding outgoing line side is series at, the protection element is self- recoverage insurance
Silk.
Preferably, the protection circuit is connected in parallel with resettable fuse by resistance and constituted.
Preferably, the protection element is fixedly installed in the batch meter being connected with the voltage transformer.
Preferably, the protection element is plug-in type resettable fuse, and the plug-in type resettable fuse is also connected with
There is binding post.
Therefore, the utility model uses a kind of voltage transformer winding protection device of said structure, simple structure cost
It is low, voltage transformer and equipment can be effectively protected, while can be with self- recoverage to normal condition, it is not necessary to manual reversion.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Specific embodiment
Embodiment
Fig. 1 is a kind of voltage transformer winding protection apparatus structure schematic diagram of the utility model, as shown in figure 1, including electricity
Pressure transformer 1, voltage transformer 1 includes first winding 11, iron core 12 and Secondary Winding 13, also including be series at it is described once
Protection circuit 2 between the neutral point of winding 11 and ground and it is series at the protection element 3 of the outgoing line side of Secondary Winding 13.
Protection circuit 2 is connected in parallel with resettable fuse 4 by resistance and constituted, simple structure, makes and use cost is low,
The effect of harmonic elimination overvoltage protection is served, while not influenceing the normal of power system to use.
Protection element 3 is fixedly installed in the batch meter being connected with voltage transformer 1, protection element 3 in the present embodiment
From plug-in type resettable fuse, plug-in type resettable fuse is also associated with binding post, follow-up wiring is carried out, when secondary
When winding passes through larger current, rapid limitation electric current passes through, so that protect the Secondary Winding of voltage transformer 1 not to be burned out, failure
After exclusion, at normal temperatures after certain hour, voluntarily recover normal condition, realize voltage transformer normal work.
Therefore, the utility model uses a kind of voltage transformer winding protection device of said structure, simple structure cost
It is low, voltage transformer and equipment can be effectively protected, while can be with self- recoverage to normal condition, it is not necessary to manual reversion.
Above is specific embodiment of the present utility model, but protection domain of the present utility model should not be limited to this.Appoint
How those of ordinary skill in the art are in the technical scope disclosed by the utility model, the change or replacement that can be readily occurred in,
Should all cover within protection domain of the present utility model, therefore protection domain of the present utility model should be limited with claims
Fixed protection domain is defined.
