Abstract
The utility model relates to a transformer supersound office puts a detection sensor high position and arranges device, its major technical features is: including last metal crate, lower metal crate and insulating bar, metal crate and last metal crate link together through the positioning bolt of metal crate and last metal crate both ends setting down, insulating bar installs the bottom of metal crate one end under, all installs strong magnet at last metal crate and metal crate's the other end down, installs rubber and compresses the pad in the metal crate inboard under, at last metal crate. The utility model relates to a rationally, the structure is simple and clear, safe and reliable, fixed convenient, has solved transformer ultrasonic method partial discharge detector, and the high position problem of arranging of the detection sensor of large -scale transformer has improved test efficiency, has promoted the detection security.
Description
Technical field
The utility model belongs to transformer ultrasound partial discharge detection technique field, the high-order arrangement apparatus of especially a kind of transformer ultrasound partial discharge detecting sensor.
Background technology
When inside transformer generation partial discharge phenomenon, the energy of its abrupt release makes intermolecular generation sharp impacts, outwards send ultrasound wave, propagate towards periphery with spherical wave form in transformer oil, as long as magnetic adsorption type sonac is adsorbed on transformer oil box outer wall, the ultrasound wave that electric discharge produces just can be received.Exactly because ultrasonic method has the features such as antijamming capability is excellent, station-keeping ability is strong, be widely used in the Partial Discharge Detection of transformer at the scene.
At the scene in test, needing sonac to be arranged in transformer body fuel tank surrounding, in order to realize accurate positioning function, needing the sensor arranged to reach 16 ~ 32.Due to capacity and the Physical design factors of high-power transformer, body height is by more than 3 meters, site layout project for high position probe is abnormal difficult, at present, usually adopts the artificial arrangement of staircase, due to human body and electrified body hypotelorism, there is potential safety hazard, and the facilities such as repeatable operation staircase, also greatly reduce test efficiency, therefore, in the urgent need to configuring more convenient, reliable high-order stationary installation to realize the precise acquisition function of ultrasonic signal.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of transformer ultrasound partial discharge detecting sensor reasonable in design, esy to use, safe and reliable high-order arrangement apparatus.
The utility model solves its technical matters and takes following technical scheme to realize:
The high-order arrangement apparatus of a kind of transformer ultrasound partial discharge detecting sensor, comprise metal framework, lower metal framework and insulating bar, the bolt that described lower metal framework and upper metal framework are arranged by lower metal framework and upper metal framework two ends links together; Described insulating bar is arranged on the bottom of lower metal framework one end, is all provided with strong magnets, inside upper metal framework, lower metal framework, is provided with rubber compression pad at the other end of upper metal framework and lower metal framework.
Described lower metal framework and upper metal framework are semicircular structure.
Described strong magnets is arranged on upper metal framework and lower metal framework respectively by mounting method.
Advantage of the present utility model and good effect are:
The utility model is reasonable in design, and structure is simple and clear, safe and reliable, fixing convenient, and solve in transformer ultrasonic method Partial Discharge Detection, the high-order Layout Problem of the detecting sensor of high-power transformer, improves test efficiency, improve detect security.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
In figure, metal framework, 4-insulating bar, 5-powerful magnet, 6-sonac, 7-rubber clamping pad under the upper metal framework of 1-, 2-bolt, 3-.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
The high-order arrangement apparatus of a kind of transformer ultrasound partial discharge detecting sensor, as shown in Figures 1 and 2, comprise metal framework 1, lower metal framework 3 and insulating bar 4, described lower metal framework and upper metal framework are semicircular structure, and are linked together by the bolt 2 that lower metal framework and upper metal framework two ends are arranged.Described insulating bar is arranged on the bottom of lower metal framework one end, is pasted with strong magnets 5, inside upper metal framework, lower metal framework, is provided with rubber compression pad 7 at the other end of upper metal framework and lower metal framework.In use, sonac 6 is put into upper metal framework, lower metal framework surrounds in circular configuration, bolt threadedly realizes metal framework and lower reliable connection between metal framework and sonac, and control the snap-in force to sonac by the rubber clamping pad inside upper metal framework and lower metal framework, realize close positioning; Insulating bar realizes remote-controlled operation function, guarantees that a high position is arranged and ensures installation effectiveness and security; Strong magnets embeds in metal framework, for being connected with transformer body fuel tank, to realize high-order arrangement apparatus location and fixed function; Metal framework for carrying each group of parts, and realizes linking and the fixed function of each inter-module.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in embodiment; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
