Abstract
An electricity theft prevention type high voltage current transformer comprises an epoxy resin master insulator and a mounting bottom board, a primary winding, a secondary winding and an iron core are cast into an integral assembly by means of mixed pouring via resin, an wire outlet end of the secondary winding is connected with a cable led out to outside of the epoxy resin master insulator, two symmetrical adjusting boards are arranged at the lower end of the mounting bottom board and are of semi-framed structures made of folded steel plates, one face of each adjusting board is provided with a slot, the other face of each adjusting face is provided with an adjusting hole, and the slots of the two adjusting boards are respectively fixed with two mounting holes on the mounting board boards through bolt components. Since the cable is used as a leading-out wire of the secondary winding, the high voltage current transformer is large in creepage distance, high in insulation strength and fine in electricity theft prevention capacity, and increases safety performance, and additionally, the high voltage current transformer is fine in universal and convenient in use by adopting the adjusting boards to adjust mounting sizes.
Description
Technical field
The utility model relates to a kind of instrument transformer, refers more particularly to a kind of high-tension current inductor.
Background technology:
When high-tension current inductor is used for electric power system generation earth current; be used with protective relaying device; make the device element action realize protection or monitoring. high-tension current inductor is wide in variety, can adapt to the needs of various protective devices and the various operational modes of electric power system.
At present, high-tension current inductor commonly used adopts casting insulated architecture, comprises epoxy resin main insulation, base plate is installed, and winding, secondary winding and an iron core are poured into black box with mixed with resin; Secondary winding is connected with the secondary connection post with lead, and the secondary connection post uses poured with epoxy resin on main body.Because the secondary connection post exposes, not only steal electric molecule can be easily at instrument transformer secondary connection terminal place short circuit with looseningly steal electricity, and the high voltage that produces of the second open circuit safety that directly threatens the person and equipment.In addition, the installing hole that base plate is provided with fixed range is installed, is had only a kind of installation dimension, the replacement of instrument transformer is installed extremely inconvenient.
The utility model content
The purpose of this utility model is the deficiency that overcomes prior art, but and provide a kind of multistation simple in structure, reasonable in design install, easy for installation, dielectric strength is high, the high-tension current inductor of safe in utilization, thief-proof good electrical property.
The technical scheme that technical problem adopted that solves is: the anti-fraudulent use of electricity type high-tension current inductor, comprise epoxy resin main insulation, base plate is installed, winding, secondary winding and an iron core are poured into black box with mixed with resin, the leading-out terminal that it is characterized in that above-mentioned secondary winding is connected with cable, leads to the outside of epoxy resin main insulation.Because, cancelled the secondary connection post of original technology, cable is directly drawn from secondary winding inside, can directly receive use occasions such as corresponding switch cubicle, just avoid adopting originally instrument transformer secondary connection terminal place short circuit and the loosening electricity of stealing, insulation property are improved, and are safe and reliable.
In concrete the enforcement, be provided with two symmetrical adjustable plates in installation base plate lower end, the half shaped as frame structure of adjustable plate for being converted into steel plate, the one side of adjustable plate is provided with slot, the other one side of adjustable plate is provided with adjustment hole, and the slot of two adjustable plates is fixed with bolt assembly with two installing holes that base plate is installed respectively.During use, can adopt select adjustable plate slot and fixed position between two installing holes of base plate is installed, determine the adjustment hole distance of adjustable plate, to reach needed installation dimension, versatility is good.
The beneficial effects of the utility model are: owing to adopt the lead-out wire of cable as secondary coil, it is big to have a creepage distance, and the dielectric strength height has increased security performance, antitheft good electrical property;
In addition, adopt adjustable plate to regulate installation dimension, versatility is good, easy to use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is the schematic diagram that the utility model embodiment master looks;
Fig. 2 is the schematic diagram of the utility model embodiment side-looking.
Fig. 3 is the schematic diagram of the utility model embodiment adjustable plate.
Among the figure 1, epoxy resin main insulation 2, cable 3, bolt assembly 4, adjustable plate 5, base plate 41, adjustment hole 42, slot are installed
Embodiment:
As shown in Figure 1, 2, the utility model embodiment is the anti-fraudulent use of electricity type high-tension current inductor, comprise epoxy resin main insulation 1, base plate 5 is installed, winding, secondary winding and an iron core are poured into black box with mixed with resin, cable 2 is directly drawn from secondary winding inside.Because, cancelled the secondary connection post of original technology, cable 2 is directly drawn from secondary winding inside, can directly receive use occasions such as corresponding switch cubicle, just avoid adopting originally instrument transformer secondary connection terminal place short circuit and the loosening electricity of stealing, insulation property are improved, and are safe and reliable.Be provided with two symmetrical adjustable plates 4 in installation base plate 5 lower ends, among Fig. 3, the half shaped as frame structure of adjustable plate 4 for being converted into steel plate, the one side of adjustable plate 4 is provided with slot 42, it is fixing with bolt assembly 3 with two installing holes that base plate 5 is installed respectively that the other one side of adjustable plate 4 is provided with the slot 42 of 41, two adjustable plates 4 of adjustment hole.During use, can adopt select adjustable plate 4 slot 42 and fixed position between two installing holes of base plate 5 is installed, determine adjustment hole 41 distances of two adjustable plates 4, to reach needed installation dimension, versatility is good.
Claims (2)
