Abstract
A 10KV voltage transformer comprises a C-shaped iron core, a primary coil, a secondary coil, a shielding net, an insulating resin casting body, a foot insert and a mounting bottom plate. The secondary coil is sheathed on the C-shaped iron core; the primary coil is sheathed at the outer part of the secondary coil; the peripheries of the coil and the iron core are added with a ring of shielding net; a space between the primary coil and the secondary coil, and the space between the shielding net and the primary coil all adopt insulating resin to be cast into the integral insulating resin casting body; the lower part of the insulating resin casting body is provided with a secondary terminal box; two leads of the primary coil are welded with elastic contact sleeves used for being inserted by a cable plug, thus realizing the connection between the transformer and an external power supply; and the foot insert is fixedly connected with the mounting bottom plate and installed at the bottom end of the insulating resin casting body. The 10KV voltage transformer adopts an integral structure design, reduces the occupying space due to small volume and light weight, is easy to be installed in any direction, increases the over-pressure resisting capability, and has long service life.
Description
Technical field
The utility model relates to the defeated change equipment of electric power, particularly relates to a kind of 10KV voltage transformer.
Background technology
The voltage transformer of measuring voltage, electric energy or relay protection device in the electric power system; traditional plain edition oil immersed type voltage transformer, its insulation system adopts insulating paper, transformer oil and porcelain insulator more, and this voltage transformer exists that volume is big, to take up an area of the space big; and it is heavy; easy to leak oil causes inflammable, contaminated environment, and the secondary capacity is low; the anti overvoltage ability is low; shortcomings such as working life is low, product need regularly special the maintenance and maintenance, cause maintenance, repair cost height.
Summary of the invention
The technical problems to be solved in the utility model, it is little to provide a kind of volume, in light weight, dwindles to take up an area of the space, and product anti overvoltage ability is strengthened, and office puts for a short time, and obviously improve useful life, reduces the 10KV voltage transformer of maintenance cost.
The technical scheme that adopts is:
10KV voltage transformer (product J DZ12-10RG type) comprises C sections core, primary winding, secondary coil, gauze screen, insulating resin pour mass, footing inserts and base plate is installed.Described secondary coil is sleeved on the C sections core, primary winding is sleeved on the secondary coil outside, make primary winding and secondary coil keep the space of a setting, the periphery of primary winding, secondary coil and C sections core adds a circle gauze screen, between space between primary winding and the secondary coil, gauze screen and the primary winding, all adopt insulating resin to pour into integral insulation resin-cast body.The footing inserts is four, the fixedly connected installation base plate in footing inserts bottom, and the footing inserts is contained in insulating resin pour mass bottom, and the footing inserts links to each other with gauze screen.
Bottom one side of above-mentioned insulating resin pour mass is provided with the secondary terminal board, is provided with secondary cable in the secondary terminal board and clamps.
Two flexible contact sleeves of wire bonds of above-mentioned primary winding, the Elastic Contact cover is cast in the insulating resin pour mass, is installed with spring in the Elastic Contact cover, is convenient to the grafting of cable plug.
Above-mentioned primary winding and secondary coil are respectively equipped with the primary winding skeleton and the secondary coil skeleton of consolidate coil.
The utility model has the advantages that:
1, coil adopts the low magnetic density design, increases the number of turn of layer insulation thickness and coil, greatly reduces the interlayer field intensity of product, and the anti-overvoltage capabilities of product is strengthened, and office puts for a short time, and product obviously improves useful life.
2, all be welded with the Elastic Contact cover on two of primary winding lead-in wires, and be cast in the insulating resin pour mass, stud with spring during the finished product assembling in cover, in cover, the office of favourable limits product puts the shielding of the wedge angle burr of both ends of the spring.
3, adopt C sections core (substituting laminated core), the no-load loss and the no-load current of C sections core are all little, have improved the on-load ability of product, have also improved operating efficiency simultaneously, as long as coil is enclosed within on the iron core, get final product (sign indicating number iron can be very time-consuming in the traditional handicraft) with steel band is fastening.
4, shell adopts equipotential (earth potential) design, and promptly product surface is not charged.Coil and iron core periphery add a circle gauze screen, gauze screen links to each other with four footing inserts, the footing inserts links to each other with base plate, chassis ground, gauze screen is ground connection then, and behind the leader cable head crust good earth, the pour mass surface that therefore reaches instrument transformer is not charged, guarantee that so promptly instrument transformer not to the cabinet discharge, also guarantees the safety of the person.
5, the utility model adopts overall construction design, and volume is little, in light weight, dwindled the occupation of land space, is easy to the installation of any direction.
