Abstract
The utility model discloses a current transformer capable of providing insulation damage signals. The current transformer comprises a primary conducting part, a secondary coil and an epoxy-resin main body, wherein the primary conducting part and the secondary coil are cast to form a whole body by epoxy resin; and the epoxy-resin main body is provided with a conducting ring. According to the current transformer disclosed by the utility model, the epoxy-resin main body is provided with the conducting ring, the insulation damage condition of the transformer is judged by online detection on the insulation change state of the current transformer, accidents caused by insulation aging damage are avoided by virtue of the action protection of an online monitoring system, and thus the system security of power lines is guaranteed.
Description
Technical field
The utility model relates to the instrument transformer technical field, relates in particular to
OnePlant the current transformer that the insulation damages signal can be provided.
Background technology
Current transformer commonly used is in the same place through poured with epoxy resin by primary conductive spare, secondary winding and secondary connection terminal in structure usually, and secondary winding is on ring structure iron core, and it mainly acts on is that metering, measurement and the protection that is used for power circuit provides signal.Current transformer insulation damages can occur when the power circuit long-play.When abnormal conditions appear in insulation, if do not take appropriate measures, accidents such as circuit road puncture can appear, influence the normal operation of power circuit, cause certain potential safety hazard.
The utility model content
The utility model is the shortcoming to above-mentioned existence, and a kind of current transformer is provided, and it is simple in structure, and the state of insulation when its operation can be provided, actively is protected when the insulation damages to guarantee on-line monitoring system, assurance power circuit safe and reliable.
The technical scheme that technical problem adopted that the utility model solves is:
A kind of self current transformer of insulation damages signal can be provided, comprise primary conductive spare, secondary coil and body of epoxy resin, primary conductive spare and secondary coil are used the poured with epoxy resin one, it is characterized in that body of epoxy resin is provided with conducting ring.
During practical implementation, body of epoxy resin is provided with a circle boss, and boss is provided with groove, and above-mentioned conducting ring is embedded in the groove.
During use, the utility model conducting ring is connected with on-line monitoring system, during the operation of the utility model current transformer; Conducting ring can be sensed the signal of telecommunication; When the body of epoxy resin insulation changed, the signal of telecommunication that conducting ring is sensed also can change, and on-line monitoring system can detect the state of insulation of the utility model current transformer in real time; When abnormal conditions such as ageing of insulation damage occurring; On-line monitoring system can send instruction, realizes action protection, to guarantee the system safety of power circuit.
The beneficial effect of the utility model is: the utility model is established conducting ring on body of epoxy resin; Insulation variable condition through online detection current transformer; Judge the insulation damages situation of instrument transformer self; The line monitoring system action protection has been avoided damaging the accident that causes because of ageing of insulation, has guaranteed the system safety of power circuit.
Description of drawings
Below in conjunction with accompanying drawing and embodiment utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, primary conductive spare 2, epoxy resin 3, secondary coil 4, conducting ring 5, installation base.
Embodiment
In Fig. 1; A kind of self current transformer of insulation damages signal can be provided, comprise primary conductive spare 1, secondary coil 3 and body of epoxy resin 2, secondary coil 3 is on ring structure iron core; Primary conductive spare and secondary coil are used the poured with epoxy resin one; Body of epoxy resin 2 is provided with installation base 5, and installation base 5 is provided with groove, is provided with in the groove that conducting ring 4 is embedded in installation base 5.During concrete the use, the secondary connection terminal may be cast on the installation base 5, can be provided with installing hole at installation base 5 simultaneously.Conducting ring 4 is connected with on-line monitoring system, and during the current transformer operation, conducting ring 4 can be sensed the signal of telecommunication; When the body of epoxy resin insulation changed, the signal of telecommunication that conducting ring 4 is sensed also can change, and on-line monitoring system can detect the state of insulation of current transformer in real time; When abnormal conditions such as ageing of insulation damage occurring; On-line monitoring system can send instruction, realizes action protection, to guarantee the system safety of power circuit.
