Abstract
The utility model discloses a dry-type compound insulation high-voltage current mutual inductor which comprises a capacitor core body, umbrella skirts, a secondary winding and a box body. A heater is arranged inside the box body. A controller is arranged and connected with the heater. Due to the fact that the heater is arranged inside the box body, the interior of the bottom of the box body is constantly kept in a dry state through heating operation of the heater, insulating performance of the mutual inductor is improved, and safety of a power grid is strengthened.
Description
Technical field
The utility model relates to the instrument transformer technical field, relates in particular to a kind of dry type compound inslation current transformer.
Background technology
Dry type compound inslation high-tension current inductor generally includes electric capacity core body, full skirt, secondary winding and bottom casing.What existing dry type compound inslation high-tension current inductor adopted all is winding of " U " shape, adopt capacitor type main insulation, winding of " U " shape seals separately with the sealed tube of organic material, and the bottom of a winding of " U " shape is fixed in the packing less base cabinet.Because have pressure reduction and the temperature difference inside and outside the casing, moisture very easily condenses into the globule in product inside greatly descend the product electric property, generally adopt in the bottom in the industry and open an aperture, with the balance box inside and outside differential pressure.For dry type compound inslation current transformer, its end screen is sealed in the organic material sealed tube, if the organic material sealed tube has the situation (bonding bad such as local defect or two sections sealed tube lap-joints) of partial failure, moisture also can slowly penetrate in the sealed tube and sink to " U " shape bottommost, cause the inner free discharge aggravation of instrument transformer, inner creeping discharge, the current transformer insulation degradation, under the long term of work field intensity, make a pair of or several to the puncture of main capacitance screen, cause Fault of Insulating Breakdown, brought hidden danger to power grid security.
The utility model content
The purpose of this utility model is that purpose provides a kind of dry type compound inslation high-tension current inductor at the problem of above-mentioned prior art existence, and bottom half inside keeps dry state always, to improve the insulation property of product, has strengthened the fail safe of electrical network.
For achieving the above object, the utility model has adopted following technical scheme to be: a kind of dry type compound inslation high-tension current inductor, comprise electric capacity core body, full skirt, secondary winding and casing, it is characterized in that being provided with heater in the casing, be provided with controller and be connected with heater.Because the utility model is provided with heater in casing, by the unlatching of controller control heater, heater adds work, moisture also can distribute by the aperture of bottom half, inside keeps dry state always, improves the insulation property of product, has strengthened the fail safe of electrical network.
During concrete enforcement, controller is connected with humidity sensor.When the upper limit of box house humidity greater than the humidity of setting, controller starts heater work, and when the lower limit of box house humidity less than the humidity of setting, controller stops heater work, guarantees that box house keeps dry, and improves the product insulation property.
During concrete enforcement, controller is located on the casing, and controller is provided with display screen.From display screen, can observe moisture condition in the casing.
The beneficial effects of the utility model are: the utility model is provided with heater in casing, add work by heater, keeps bottom half inside to keep dry state always, improves the insulation property of product, has strengthened the fail safe of electrical network.
Description of drawings
Below in conjunction with drawings and Examples utility model is further specified.
Fig. 1 is the prior art constructions schematic diagram;
The main TV structure schematic diagram of Fig. 2 the utility model embodiment;
The side-looking part section structural representation of Fig. 3 the utility model embodiment.
Among the figure: 1, full skirt 2, casing 3, heater 4, controller.
Embodiment
Among Fig. 2 and Fig. 3, a kind of dry type compound inslation high-tension current inductor, comprise electric capacity core body, full skirt 1, secondary winding and casing 2, be provided with heater 3 in the casing 2, be provided with controller 4 and be connected with heater 3, controller 4 is connected with humidity sensor, and controller 4 is located on the casing 2, controller 4 is provided with display screen, can observe moisture condition in the casing 2 from display screen.When box house humidity greater than 50% the time, controller 4 starts heater 3 work, moisture also can distribute by the aperture of casing 2 bottoms, when casing 2 interior humidities less than 40% the time, controller 4 stops heater work, guarantee that casing 2 inside keep dry, improve the insulation property of product, strengthened the fail safe of electrical network.
