Before the technical solutions of the present application are introduced, it is necessary to explain the background of the invention of the present application.
It is common that, in the related art, a method for measuring electromagnetic disturbance of a high-voltage switch cabinet mainly measures through a voltage probe and a current probe, when measuring an internal electromagnetic disturbance signal of an intelligent high-voltage switch cabinet, due to the limitation of an intelligent component mounting position and a switch cabinet structure, a measuring probe is difficult to be accurately fixed at a point to be measured, and meanwhile, when measuring the internal electromagnetic disturbance signal, a signal line of the measuring probe needs to be reliably fixed in order to avoid the signal line from being dragged due to the action of the switch cabinet.
Based on the above difficulties of the inventor, the inventor provides an auxiliary device for measuring electromagnetic disturbance signals of an intelligent high-voltage switch cabinet. The hollow flexible insulating conduit 50 is used as a protection and support component of the signal wire of the measuring probe, so that the problems of signal wire abrasion and dragging possibly caused in the measuring process can be reduced; the supporting sucker 40 is utilized to fix the signal wire of the measuring probe, and the self structure of the high-voltage switch cabinet can be fully utilized to support the signal wire of the measuring probe. Therefore, the signal wire and the measuring probe of the measuring probe are effectively fixed, the adverse effect of the looseness of the signal wire or the measuring probe of the measuring probe on the measurement is avoided, and the measurement accuracy is improved.
In addition, the supporting suction cups 40 are fixedly arranged on the flexible insulating conduit 50 through the adjustable telescopic pipes 60, the electromagnetic field measuring probe can be fixed by the arrangement of the adjustable telescopic pipes 60 and the auxiliary fixing suction cups 30 of the probe clamp 20, and the requirement of electromagnetic field measurement in the narrow space in the intelligent high-voltage switch cabinet can be met. Therefore, the invention is created.
Referring to fig. 1-2, an embodiment of the present application provides an auxiliary device for measuring an electromagnetic disturbance signal of an intelligent high-voltage switch cabinet, including:
a hollow flexible insulated conduit 50 for receiving the measurement probe signal wires;
a support chuck 40 fixedly disposed on the flexible insulating conduit 50;
a probe holder 20 fixedly disposed on the flexible insulating tube;
and a fixing suction cup 30 fixedly disposed on the probe holder 20 for providing a positioning support for holding the probe to which the measuring probe is fixed.
The signal wire of the measuring probe and the measuring probe are connected to form measuring equipment for measuring electromagnetic disturbance signals existing in the intelligent high-voltage switch cabinet, and the measuring equipment belongs to common knowledge.
Here, although the subject matter "auxiliary device for electromagnetic disturbance signal measurement of intelligent high-voltage switch cabinets" is referred to herein with words "electromagnetic disturbance signal measurement", these words superficially contain the measurement tool definition for the object to be assisted. However, these words are to be understood as a usage environment, which is merely an exemplary illustration and does not constitute a substantial limitation of the auxiliary device of the present application. Other objects in any form, namely measuring tools needing fixed support for ensuring the measuring accuracy, are all suitable for the technical scheme of the application. For convenience of description, the electromagnetic disturbance signal is used as an example hereinafter, and the demonstration of the form of other non-sidewalk footpaths is omitted to avoid the following brevity.
The specific structure of the probe holder 20 may be implemented in any form having a holding function, such as a clamp for holding a cable or fixing an inlet pipe of a gas range, or a clip applied to clothes to be dried, but not limited thereto.
As for the flexible insulated conduit 50, it may be any form of pipe such as an insulated pipe or the like for electricians or a rubber pipe or the like.
As for the implementation of the suction cups supporting the suction cup 40 and fixing the suction cup 30, any suction cup known to those skilled in the art may be used. The specific mechanism of the suction cup does not substantially affect the achievement or non-achievement of the claimed technical effect.
As an exemplary implementation in which the fixed suction cups 30 are disposed on the probe holder 20, the probe holder 20 is provided with a capstan 21 for winding a flexible connecting member for connecting the fixed suction cups 30.
With this, the considerations of the winch 21 are: the length of the flexible link is adjusted by the capstan 21 being rotated by an external force so that the fixed suction cup 30 can reach a designated fixed position.
The flexible connecting member may be a rope of any insulating material, such as nylon rope.
In an exemplary embodiment, the probe holder 20 is provided with a through hole 20 a.
Thus, the design considerations for the through-hole 20a are: the measurement probe signal line can directly penetrate into the flexible insulating conduit 50 through the through hole 20a, and the measurement probe signal line is prevented from extending from the outside of the probe clamp 20 to the flexible insulating conduit 50 in a bypassing way. Because of this routing of the "detour" extension of the measurement probe signal wires, it is easy to cause the measurement probe signal wires to form a "jack-up" action on the measurement probe near the end of the measurement probe (usually the end wires have a certain hardness), which has an adverse effect on the clamping fixation of the probe holder 20.
Preferably, the through hole 20a is located at a middle position of the probe holder 20.
In an exemplary embodiment, the probe holder 20 is fixedly attached to the flexible insulated conduit 50 by an adjustable extension tube 60.
Thus, the design considerations for the adjustable bellows 60 are: by adjusting the telescopic adjustment of the telescopic rod, the height position of the probe clamp 20 relative to the flexible insulated conduit 50 is adjusted.
In an exemplary embodiment, the over-adjustable extension tube 60 is coupled to the flexible insulated conduit 50 via a universal shaft 7070.
Thus, the design considerations for the cardan shaft 70 are: the tilt attitude of the probe holder 20 with respect to the flexible insulated conduit 50 is adjusted by adjusting the rotation of the adjustable telescopic tube 60 by the cardan shaft 70.
In an exemplary embodiment, the winch 21 is provided with a crank.
The rotation of the winch 21 is operated by a crank.
Now, the operation process of the present application for fixed positioning is described with respect to a common application scenario. It should be noted that this common embodiment is not to be taken as an identification basis for understanding the essential features of the technical problem to be solved as claimed in the present application, which is merely exemplary.
Referring again to fig. 1, a specific construction flow for performing the auxiliary measurement of the disturbance signal by using the auxiliary device is as follows:
s1, selecting the appropriate length of the hollow flexible insulating guide pipe 50 and the length of the adjustable telescopic pipe 60 according to the position of equipment in the intelligent high-voltage switch cabinet to be measured, enabling a signal wire of the measuring probe to penetrate through the hollow flexible insulating guide pipe 50, and fixing the measuring probe body by a clamp in the probe clamp 20;
s2, fixing the hollow flexible insulating guide pipe 50 on the intelligent high-voltage switch cabinet body by using the supporting sucker 40, and placing the measuring probe at a signal port of the equipment to be measured or any internal space position;
s3, adjusting the extension length of the nylon wire of the winch 21 in the probe clamp 20 to enable the fixed sucker 30 to be just adsorbed on the intelligent high-voltage switch cabinet body, tightening the winch 21 to enable the nylon wire to be tightened, completing auxiliary fixing of the measuring probe and starting measurement of electromagnetic disturbance signals.
S4, in S3, if the mass of the measuring probe is small, the fixed sucker 30 can be adsorbed on two sides of the intelligent high-voltage switch cabinet, and if the mass of the measuring probe is large, the fixed sucker should be adsorbed on a cover plate at the top of the cabinet body to ensure the safety of the measuring probe and the accuracy of the measuring position.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
