The high-voltage resistor is arranged inside the insulation drawing rod, the sealing fillings are filled into the insulation drawing rod, the outer sleeve is arranged outside the insulation drawing rod, one end of the conductor outgoing line is connected with the high-voltage resistor, and the conductor outgoing line is mounted onto the insulation drawing rod via the metallic shield ring. Metal inserts are respectively mounted at two ends of the insulation drawing rod, the sealing fillings are silicon rubber, and the outer sleeve is insulation skirt made of silicon rubber. Compared with the prior art, the resistor type voltage sensor is economic, high in precision, small in volume and simple in manufacturing.
Description
Technical field
The utility model relates to a kind of voltage sensor, particularly a kind of resistor-type voltage sensor.
Background technology
At home in the distribution system, Utilities Electric Co. often requires panel switches that the size and the phase place of electric current and voltage on the circuit are provided, so that judge the fault type on the circuit, thereby takes different safeguard measures.Current signals adopts current transformer usually, and the collection of voltage signal then has diverse ways.Common way is to adopt voltage transformer (VT), but its price is comparatively expensive, uses out of doors owing to panel switches are most of in addition, and the restriction of volume is arranged again, therefore adopts voltage transformer (VT) uneconomical under most of occasions, unreasonable.Also there is producer to adopt capacitance type potential transformer, but because its manufacturing process complexity, precision is low, and is wayward, also can't use in the demanding occasion of protection.Therefore, market in urgent need is a kind of economical good, and precision height, volume are little, make simple voltage sensor.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model discloses a kind of resistor-type voltage sensor, comprising: high-tension resistive, insulated tension pole, pipe overcoat, sealing filler; Described high-tension resistive places described insulated tension pole inside, and described sealing filler fills up described insulated tension pole; Described pipe overcoat is positioned at described insulated tension pole outside.
Also comprise: conductor extension line, metallic shield ring; Described conductor extension line one end links to each other with described high-tension resistive, and described conductor extension line is installed on the insulated tension pole by described metallic shield ring.
Metal down spare is equipped with at described insulation tube two ends.
Described sealing filler is a silicon rubber.
Described pipe overcoat is the insulation full skirt that silicon rubber is made.
Compared with prior art, the utility model is economical good, and precision height, volume are little, makes simple.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As Fig. 1, a kind of resistor-type voltage sensor is characterized in that, comprising: high-tension resistive 5, insulated tension pole 4, pipe overcoat 3, sealing filler 6; Described high-tension resistive 5 places described insulated tension pole 4 inside, and described sealing filler 6 fills up described insulated tension pole 4; Described pipe overcoat 3 is positioned at described insulated tension pole 4 outsides.Metal down spare is equipped with at described insulated tension pole 4 two ends.Described sealing filler 6 is a silicon rubber.The insulation full skirt that described pipe overcoat 3 is made for silicon rubber.
Described insulated tension pole 4 is used to isolate high-low pressure.
Comprise that also conductor extension line 1, metallic shield ring 2 described conductor extension line 1 one ends link to each other with described high-tension resistive 5, described conductor extension line 1 is installed on the described insulated tension pole 4 by described metallic shield ring 2.
Say the utility model implementation procedure below in conjunction with the drawings and specific embodiments:
Metal down spare is equipped with at the two ends of described insulated tension pole 4, and as Fig. 1, A end metal down spare 8 connects the high pressure of 10KV with lead by screw and nut; B end metal down spare 7 is connected with high-voltage switch gear divide-shut brake catanator.Described conductor extension line 1 takes out voltage signal by a divider resistance 9 from voltage signal extension line 10.The utility model serves as insulated tension pole again in mechanism, be that the function of voltage sensor is integrated on the insulated tension pole, is a kind of novel " insulated tension pole ".
More than disclosed only be several specific embodiments of the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
