Description
Technical field
The present invention relates to transmission line of electricity parallel groove clamp temperature survey field, particularly a kind of device of measuring transmission line of electricity parallel groove clamp surface temperature distribution.
Background technology
Along with increasing sharply of electricity consumption client quantity, line load increases substantially, and causes the at full capacity long-term or overload operation of circuit.The problem of strain insulator shaft tower parallel groove clamp heating usually takes place in transmission line of electricity in this case, but some important line can not have a power failure immediately and handle, and has influenced the reliable and secure property of transmission line of electricity.By the investigation at scene, the statistical data of wire clamp heating in recent years, for example analyzing, the drainage parallel groove clamp takes place under overheated even the crack conditions for the reliable and secure influence of power system power supply.
In the The Study on Fault of transmission line of electricity wire clamp, particularly important for the research of wire clamp heating.Therefore, accurately measure the wire clamp temperature and for the division of the temperature province of wire clamp itself, can effectively solve the problem in the transmission line of electricity wire clamp heat run, instruct operation and the maintenance of transmission line of electricity wire clamp.Therefore the research for the wire clamp heating is very necessary, and the temperature of accurately measuring wire clamp is the key of problem, must accomplish to measure effectively and accurately.In present application, adopt infrared thermometer and infrared thermography to carry out thermometric usually.Because the two thermometric all belongs to not contact temperature-measuring, the precision of measurement is lower; For example, in the scope of 3m measuring error can reach ± 1 ℃, along with the increase of distance, this error will the exponentially type increases.
Summary of the invention
The present invention provides a kind of device of measuring transmission line of electricity parallel groove clamp surface temperature distribution in order to overcome the shortcoming deficiency that prior art exists.The present invention adopts thermopair to carry out thermometric, and the result of thermometric and thermometric zoning are combined, and has solved whether consistent problem of wire clamp surface.
The technical solution used in the present invention:
A kind of device of measuring transmission line of electricity parallel groove clamp Temperature Distribution comprises thermocouple temperature measurement probe and data collecting instrument, and described thermocouple temperature measurement probe is distributed in the parallel groove clamp surface, and described thermocouple temperature measurement probe is connected with data collecting instrument.
The number of described thermocouple temperature measurement probe is 6 or greater than 6 even number.
Described thermocouple temperature measurement probe is distributed in the parallel groove clamp surface and is specially: be symmetrically distributed in the left and right sides of parallel groove clamp surface longitudinal center line, and adjacent heat galvanic couple temperature probe spacing equates.
Beneficial effect of the present invention:
(1) according to measurement result, can judge whether the surface temperature of parallel groove clamp is consistent; As inconsistent, what rule is the time dependent characteristic of temperature that can further study zones of different have;
(2) this measuring method can effectively be measured each regional temperature on parallel groove clamp surface, can reduce the quantity of point for measuring temperature simultaneously to greatest extent, saves cost;
(3) by the measuring method of above-mentioned parallel groove clamp temperature, can be widely used in other tests relevant with thermometric such as wire clamp heat run, wire clamp thermal cycling test.

Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment
As shown in Figure 1, a kind of device of measuring transmission line of electricity parallel groove clamp Temperature Distribution comprises thermocouple temperature measurement probe and data collecting instrument, and described thermocouple temperature measurement probe is distributed in the parallel groove clamp surface, and described thermocouple temperature measurement probe is connected with data collecting instrument.
The number of described thermocouple temperature measurement probe is 6 or greater than 6 even number.
Described thermocouple temperature measurement probe is symmetrically distributed in the left and right sides of parallel groove clamp surface longitudinal center line, and adjacent heat galvanic couple temperature probe spacing equates.
Present embodiment adopts 6 thermocouple temperature measurement probes, be T type thermopair, T type thermopair claims copper-constantan thermocouple (copper/ambrose alloy thermopair, calibration T again, measurement range-200～+ 350 ℃), it is good that T type thermopair has the linearity, and thermopower is bigger, and sensitivity is higher, temperature approximately linear and replicability are good, it is fast to conduct heat, and stability and homogeneity are better, advantages such as low price.
Data collecting instrument model KH432G-LUNN, 6 thermocouple temperature measurement probes are numbered respectively 1,2,3,4,5, No. 6, and with transparent rubberized fabric thermocouple probe is glued card to the surface of parallel groove clamp in order, be connected with data collecting instrument respectively, and the numbering of popping one's head in according to thermocouple temperature measurement is divided into 6 zones to the surface of parallel groove clamp, and temperature-measuring results divided with the zone is connected, the thermocouple temperature measurement of different thermometrics numberings is popped one's head in and is recorded the temperature of region.
The distribution of parallel groove clamp is described relevant with the thermal resistance size according to thermal conduction study, and therefore the surface with parallel groove clamp is divided into 6 zones, and is specific as follows:
(1) length of measurement parallel groove clamp is made as X;
(2) along three zones, left side of parallel groove clamp surface longitudinal center line, three zones, right side;
(3) left side and the position of three points for measuring temperature in right side, respectively apart from the parallel groove clamp base apart from x/4,2x/4,3x/4.
The present invention is behind parallel groove clamp surface arrangement measurement point, and the distribution that draws temperature according to measurement result, can judge whether the surface temperature of parallel groove clamp is consistent; As inconsistent, what rule is the time dependent characteristic of temperature that can further study zones of different have, and measures the Temperature Distribution of wire clamp, provides based measurement for its failure cause of research and fault signature.
Above-described embodiment is preferred implementation of the present invention; but embodiments of the present invention are not limited by the examples; other any do not deviate from change, the modification done under spiritual essence of the present invention and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
