Description
Technical field
The invention belongs to insulating tube type busbar technical field, especially a kind of tube type bus displacement monitoring based on ultrasound
System.
Background technology
As novel bus form fast-developing in recent years, insulating tube type busbar is because it is small with appearance and size, installation
The advantages that simple and convenient, current-carrying capacity is big, good insulation preformance and accommodative ability of environment are strong and be widely used in electric system.
In substation, insulating tube type busbar has been widely used in main transformer, couples conductor between low-pressure side and distribution facility, and
Obtain certain application effect.Therefore, with insulating tube type busbar gradually get people's approval, application is increasingly extensive, absolutely
The monitoring system of edge tube type bus causes the concern of numerous scholars, has great application prospect and engineering significance.
However, also exposing many problems in the application process of tube type bus.Apply the cast in substation female
Line is easy to be influenced by the operating status of electric power networks and the temperature change of external environment, so as to cause there is equipment heat expansion
The appearance of the phenomenon that shrinkage, this phenomenon can cause to generate small displacement between insulating tube type busbar and bus bar cupport, to
Influence the safe operation of electric system.After insulating tube type busbar and bracket generate displacement, tube type bus lower part is played support and is made
Porcelain vase can bear larger extra-stress because of the relative friction that displacement generates.When tube type bus and bracket generate small position
It moves and system longtime running is under the operating mode of overload, support the service life of porcelain vase that can greatly shorten, in some instances it may even be possible to can occur to support porcelain
Pernicious safe operation accident caused by bottle breakage.
When for bus run offset phenomena has carried out mechanical analysis and experience and has calculated, it is indicated that displacement parameter is power train
Insulating tube type busbar is badly in need of the Important Parameters of monitoring in system operational process.In recent years, with the increasingly development of automatic technology, pipe
The displacement monitoring of type busbar is also developing progressively on-line monitoring from traditional artificial observation, such as the displacement based on laser ranging is supervised
Survey technology has obtained certain application.Although laser ranging can realize higher precision, this direct measuring method without
Method meets the objective requirements such as live outdoor installation, operation high pressure.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of tube type bus displacements based on ultrasound to supervise
Examining system can carry out insulating tube type busbar long term monitoring and assess its contact situation between wire clamp in time and realize position
Shifting amount real time monitoring function.
The present invention solves its technical problem and following technical scheme is taken to realize：
A kind of tube type bus system for monitoring displacement based on ultrasound, including ultrasonic distance-measuring sensor and reflecting plate, institute
Ultrasonic distance-measuring sensor is stated on the metallic support of one side-lower of tube type bus, the reflecting plate is mounted on another side pipe
Type busbar end point, ultrasonic distance-measuring sensor are oppositely arranged with reflection plate surface.
The ultrasonic distance-measuring sensor and reflecting plate are to tilt to be oppositely arranged.
The reflecting plate is stainless steel reflecting plate.
Advantages of the present invention and effect：
The present invention is directed to tuning drive gear formula tube type bus, can be carried out to insulating tube type busbar using ultrasonic technology long-term
It monitors and assesses its contact situation between wire clamp in time and realize displacement real time monitoring function, avoid existing laser
Ranging cannot be satisfied the shortcomings of live outdoor installation, operation high pressure, and can meet outdoor installation using ultrasonic distance-measuring sensor makes
With needs, measurement frequency is can control, tube type bus displacement monitoring field is can be widely used for.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention；
Fig. 2 is the displacement parameter monitoring principle schematic diagram of the present invention.
Specific implementation mode
The embodiment of the present invention is further described below in conjunction with attached drawing：
A kind of tube type bus system for monitoring displacement based on ultrasound, as shown in Figure 1, including ultrasonic distance-measuring sensor 3
With stainless steel reflecting plate 2, the ultrasonic distance-measuring sensor is mounted on 4 side of metallic support below a tube type bus, institute
It states stainless steel reflecting plate and is tiltedly mounted on 1 end point of tube type bus, ultrasonic distance-measuring sensor reflects plate surface phase with stainless steel
To setting.Ultrasonic signal is sent out by ultrasonic range finder sensor and receives stainless steel reflecting plate transmitting signal, it is super to measure
Sound ranging sensor is at a distance from stainless steel reflecting plate, to realize displacement real time monitoring function.
The operation principle of the present invention sends sensor and reflecting plate as shown in Fig. 2, ultrasonic range finder sensor is measured in real time
The distance between be S1, each point of observation initial distance S, angle α are determined, to obtain tube type bus point of observation relative in setting
Set the real-time displacement amount l of the positions initial distance S.Physical relationship is as follows：
H=h1-h2；
α=arcsin (h/S)；
L=(S1-S)×cosα。
It is emphasized that embodiment of the present invention is illustrative, without being restrictive, therefore the present invention is simultaneously
It is not limited to the embodiment described in specific implementation mode, it is every to be obtained according to the technique and scheme of the present invention by those skilled in the art
Other embodiment, also belong to the scope of protection of the invention.
