Description
Technical field
The utility model is related to a kind of electrical equipment, particularly for the integrated on-pole switch cabinets of 10kV and distribution one or two times
Be used as to measure in complete set of equipments and protection miniature two-way electric resistance partial pressure voltage sensor.
Background technology
At present, the electric resistance partial pressure type voltage sensor used in power system and distribution automation system, is by pouring
The resitstance voltage divider noted in epoxy resin is constituted, and voltage sensor only has to be exported all the way.For measuring three-phase voltage
, it is necessary to could complete measurement using 6 voltage sensors during with residual voltage, i.e., 3 are served only for three-phase voltage measurement, 3 combinations
It is used as residual voltage afterwards to measure.This voltage sensor needs many to use cooperatively in the application, and installation operation is cumbersome, many
The space that voltage sensor is occupied after installing is big, it is impossible to meet power system to the integrated on-pole switch cabinets of 10kV and distribution one
The requirement of secondary complete set of equipments miniaturization.
The content of the invention
The purpose of this utility model is to provide measurement and protection integration, the miniature two-way resistance point of reduction installing space
Piezoelectricity pressure sensor.
Technical solution of the present utility model is：A kind of miniature two-way electric resistance partial pressure voltage sensor, including partial pressure electricity
Resistance, it is characterised in that be set up in parallel two-way divider resistance, two-way partial pressure electricity by certain insulation distance in epoxy resin poured body
The input of resistance is in parallel, and its one end is high voltage input terminal, and the other end is earth terminal, the measurement of output all the way of two-way divider resistance
With voltage signal, another road output equipment protection voltage signal.
The characteristics of the utility model is：Voltage sensor is used and connects the structure of two-way divider resistance, and survey can be exported simultaneously
Measure signal and equipment protection signal.The two-way divider resistance being set up in parallel is molded with poured with epoxy resin, between the two with compared with
Good insulating properties, output signal is not interfere with each other, it is ensured that the measurement accuracy of product.The small volume of product, lightweight, operation safety
Reliably, take up space small, manufacturing cost is low.
Brief description of the drawings
Fig. 1 is circuit theory diagrams of the present utility model；
Fig. 2 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, 2, miniature two-way electric resistance partial pressure voltage sensor is by certain insulation in epoxy resin poured body 5
Distance is set up in parallel two-way divider resistance 2,3, and two-way divider resistance is connected in parallel, and the circuit on one side after connecing is high voltage input terminal
U1, is connected with high-voltage connection terminal 1, and the other end is earth terminal, is connected with ground terminal 4.All the way divider resistance by resistance R1 and
R2 is in series, a, n output end output measurement voltage signal U2 of divider resistance.Another road divider resistance is by resistance R3 and R4
In series, voltage signal U3 is used in da, dn output end output equipment protection of divider resistance.
The voltage sensor that the utility model is provided has measurement signal and protection signal dual output function, applies in 10kV
In integrated one or two complete set of equipments of on-pole switch cabinet and distribution, only need to install 3 voltage sensors just can reach use requirement,
The installing space occupied is small, low manufacture cost.
