Abstract
The utility model relates to the technical field of breakers and specifically refers to an accurate measuring apparatus for an instantaneous opening and closing point of a breaker. A foil gauge and a signal processing module are arranged between an insulated pull bar and a transmission connecting lever. The foil gauge and the signal processing module are electrically connected with each other. The accurate measuring apparatus is simple in structure, convenient in operation and relatively high in utilization value, and is capable of on-line measurement.
Description
Technical field
The utility model relates to the technical field of isolating switch, and especially a kind of isolating switch is the device for accurately measuring of minute firm chalaza just.
Background technology
In traditional breaker mechanic property is measured, must guarantee that isolating switch is in off-line state, and needing provides a small loop current to it, by the break-make of electric current judge contact of breaker deciliter, thereby obtain just minute firm chalaza, the shortcoming of measuring like this is to operate comparatively loaded down with trivial detailsly, and can't realize on-line measurement.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, the just device for accurately measuring of minute firm chalaza of a kind of isolating switch is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of isolating switch is the device for accurately measuring of minute firm chalaza just, it is provided with foil gauge, signal processing module between insulated tension pole and transmission crank arm, be electrically connected between foil gauge and the signal processing module.
Have the groove one that matches with foil gauge and the groove two that matches with signal processing module above the described insulated tension pole, described foil gauge directly fixedly is attached in the groove one, and described signal processing module directly fixedly is attached in the groove two.
The beneficial effects of the utility model are: the utility model is by directly arranging foil gauge and signal processing module on insulated tension pole, simple in structure, easy to operate, measure accurately, reliable.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Among the figure: 1. insulated tension pole, 2. transmission crank arm, 3. foil gauge, 4. signal processing module, 1-1. groove one, 1-2. groove two.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The synoptic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only represents the formation relevant with the utility model.
As shown in Figure 1: a kind of isolating switch is the device for accurately measuring of minute firm chalaza just, and it is provided with foil gauge 3, signal processing module 4 between insulated tension pole 1 and transmission crank arm 2, is electrically connected between foil gauge 3 and the signal processing module 4.Have groove one 1-1 that matches with foil gauge 3 and groove two 1-2 that match with signal processing module 4 above the described insulated tension pole 1, described foil gauge 3 directly fixedly is attached in groove one 1-1, and described signal processing module 4 directly fixedly is attached in groove two 1-2.
Because foil gauge 3 is set directly at above the insulated tension pole 1, so its induction is comparatively accurately sensitive, the force value of measuring is more accurate, thereby reaches the just purpose of minute firm chalaza of accurately judging contact of breaker.
Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection domain of the present utility model.
