Abstract
The utility model discloses a high-voltage current transformer which is suitable for the automatic control system of 10KV and 35KV electric networks. The high-voltage current transformer which is formed by casting epoxy resin uses an epoxy glass cloth plate or a ceramic plate as an insulating skeleton and has the characteristics of small size, low cost and convenient installation.
Description
The utility model relates to a kind of to carrying out the current transfer device of current measurement in the high-tension circuit.
At present, the known high-tension current inductor that is applicable to the above electrical network of 10KV, most situations are connected with ammeter or electric energy meter, because precision and withstand voltage requirement cause at present general high-tension current inductor volume big, price is expensive.The current signal that receives from instrument transformer in automatic control system flows to electronic control system, can guarantee the certainty of measurement of The whole control system by adjusting the related parameter that has of electronic circuit, and the required precision of current transformer itself is relaxed to some extent.
The purpose of this utility model provides that a kind of volume is little, and cost is low, the high-tension current inductor that uses in 10KV or 35KV electrical network automatic control system.
The purpose of this utility model is achieved in that and processes two parallel square through holes with lateral vertical in a cuboid epoxy resin bonded fiber or ceramic wafer side, processing two grooves in these two sides again communicates with square opening, coiling square shape iron core in square hole and groove, and lateral vertical up and down between two planes processing four microscler through holes, this microscler through hole keeps certain distance with the square hole of placing iron core and groove and can not communicate, between two adjacent microscler through holes respectively around on enamelled wire, as first siding ring and second siding ring; At coil and iron core place, after annotating upward epoxy resin, treating resin solidification, coat the high pressure gauge finish paint in appearance.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structure chart.
The last figure of Fig. 1 is a front view, is vertical view below, and 1 is the instrument transformer first siding ring among Fig. 1, and by the enamelled wire coiling, the diameter of enamelled wire is by current transformer.
The decision of primary side current size; The 2nd, iron core is formed by the coiling of cold band shape silicon steel sheet; The 3rd, expoxy glass plate cloth or ceramic wafer; The 4th, the instrument transformer second siding ring, by the enamelled wire coiling, its line is decided via the secondary side current size.
Owing to adopt structure of the present utility model, the volume of instrument transformer is reduced greatly, cost also reduces many.And it is easy for installation.
Claims (1)
- A kind of high-tension current inductor, form by first siding ring, second siding ring, iron core and insulating material, it is characterized in that: process two parallel square through holes of lateral vertical therewith in the side of a cuboid epoxy resin bonded fiber or ceramic wafer, process two grooves in these two sides again and communicate, coiling square shape iron core in square hole and groove with square opening; And lateral vertical process four microscler through holes up and down between two planes, this microscler through hole keeps certain distance with the square opening of placing iron core and groove and can not communicate, between two adjacent microscler through holes respectively around on enamelled wire as first siding ring and second siding ring; Epoxy resin in coil and the cast of iron core place is coated the high pressure gauge finish paint in appearance behind the resin solidification.
