Background technology
At present, usefulness is measured and protected to the high-tension current inductor that uses on the domestic electrical network to electrical network, particularly insulate at 35KV and above high-tension current inductor, is oil-filled or fills the current transformer of SF6 gas as dielectric.The Primary Conductor of this current transformer is long, and caloric value is bigger, and it is bad to dispel the heat, and dynamic stability is bad.
Oil-filled high-tension current inductor is that a winding is curved " U " font, its outer alternately wrapped multiple cable paper and aluminium foil electric screen, secondary winding is sleeved on the bottom of a winding, and it is the lead-in wire position of a winding is good with the colligation of glass adhesive tape, put insulator and reinstall fuel tank, and in fuel tank, fill with oil.The high-tension current inductor that fills SF6 gas is that winding will assembling and secondary winding are contained in the container of a band insulator that is full of SF6 gas jointly.Above-mentioned high-tension current inductor is subjected to the restriction of " insulator, " " oil-filled ", " inflation " structure because of it, exist easy aging, the shortcomings such as seepage is oily, gas leakage of insulation, oil-filled high-tension current inductor is because of ageing of insulation or its inner arc discharge that produces, cause the insulating oil cracking and produce a large amount of fuel gas, fire hazardous or blast; Fill SF
6The current transformer of gas is in operation very easily, and gas leakage causes environmental pollution.Oil-filled or the inflation shortcoming of high-tension current inductor in running is: caloric value is big, heat radiation is slow, fire hazardous or blast etc.In order to guarantee the safe operation of above-mentioned high-tension current inductor, the annual needs regularly tests, overhauls high-tension current inductor, increased the workload of many maintenances.
Summary of the invention
Existing high-tension current inductor to be solved in the utility model is long because of its Primary Conductor, and the high-tension current inductor caloric value that produces is bigger, and it is bad to dispel the heat, and insulation is easily aging, seepage is oily, gas leakage, problems such as fire hazardous or blast.
Solve the technical scheme that its technical problem adopts: handstand dry type high-tension current inductor has a base, be connected with union body on the base, the union body upper end is connected with inclusion enclave, in the inclusion enclave is secondary winding, secondary winding is wrapped with the main insulation body, there is a hole at the inclusion enclave center of main insulation body and secondary winding, and Primary Conductor is passed from the hole.
Tubular armature is arranged, the outer socket full skirt of tubular armature, the umbrella limit inside scroll rolling groove of full skirt in the union body.
Two ends of Primary Conductor are connected with busbar, and busbar is the combination of line bank or line bank and primary connection plate, at two ends of the inclusion enclave of main insulation body and secondary winding insulation barrier are arranged, and Primary Conductor is passed from the center of insulation barrier.
Be connected with the secondary connection plate in the base, the connecting line of secondary winding is connected with the secondary connection plate by tubular armature.
Beneficial effect: the utility model possesses following advantage: 1., product main insulation surrounds on the secondary winding, and be positioned at the top of union body, Primary Conductor bob heat less, rapid heat dissipation; 2., do not have any dielectric, so have non-leakage, missing of ignition, do not explode, resistant sudden strain of a muscle etc.; 3., volume is little, in light weight, maintenance is simple; 4., its secondary winding precision height, according to the primary current size, its Primary Conductor can be that single turn also can be a multiturn; 5., make outer insulation jacket and full skirt, can improve hydrophobicity, ageing resistance and the anti-uv-ray etc. of outer surface with silastic material.
