Abstract
The utility model relates to a voltage sensor, which consists of an insulator, an upper polar plate and a lower polar plate, wherein the insulator serves as an upright; the upper and the lower polar plates form a capacitor; the upper polar plate is arranged at the top of the insulator; and the lower polar plate is arranged in the insulator and is positioned below the upper polar plate. The upper polar plate is in the shape of a pipe or a cup stretching axially and is nested at the center of the top of the insulator; the lower polar plate is in the shape of a cylinder stretching axially; and the cylindrical lower polar plate is formed by winding a copper foil. The voltage sensor has small volume and stable performance and is light in weight and moisture-proof. The voltage sensor is mainly used for a switching device of an AC power system and can be matched with high voltage switch cabinets, disconnecting switches, ground switches and the like of various types.
Description
Technical field
The utility model relates to a kind of voltage sensor, belongs to the voltage sensor technical field, mainly with supporting uses such as all types of high-tension switch cabinets, disconnector, grounding switches.
Background technology
Voltage transformer (VT) all is the iron-core coil formula at present, and volume heaviness, dielectric strength require high, and frequency is narrow, is easy to generate resonance, makes troubles for sampling, measurement and digital processing.
The utility model content
In order to address the aforementioned drawbacks, the utility model adopts epoxy resin to improve insulativity, does not contain iron core, avoided generation resonance, and volume is little, in light weight.
The technical scheme that the utility model adopted is: a kind of voltage sensor, form by a insulator and a common upper and lower pole plate of forming electric capacity as pillar, described top crown and bottom crown are fixedly mounted on the described insulator respectively or are arranged in the described insulator, and described bottom crown is positioned at the below of described top crown.
Described top crown can be axially extended tubulose or cup-shaped, is inlaid in the center of top of described insulator.
The top of described insulator can be provided with the top mounting flange usually, and the top crown of described tubulose or cup-shaped is provided with inner nut, and tightens together by bolt and described top flange.
Described bottom crown is arranged in the described insulator, preferably is and the axial identical axially extended tubular of described insulator.
Described tubular bottom crown can be formed by the Copper Foil coiling.
Described bottom crown can be provided with draws lead.
Can be provided with a tip jack on the described insulator, the described lead of drawing inserts described tip jack.
Described tip jack can be positioned at the side of described insulator usually, and affiliated insulator bottom is provided with the bottom mounting flange, described bottom mounting flange by bolted on described insulator.
Described insulator is preferably epoxy resins insulation.
Described insulator preferably adopts the moulding of poured with epoxy resin mode, and when moulding described upper and lower pole plate is cast in together with described insulator.
Because the utility model do not need to be provided with coil winding, therefore reduced resonance, the wide frequency range of adaptation has also simultaneously that volume is little, in light weight, a moisture proof, stable performance.The utility model mainly can be used on the switchgear of AC electric power systems, with supporting uses such as all types of high-tension switch cabinets, disconnector, grounding switches.
