Abstract
The utility model relates to the technical field of vacuum circuit breakers, particularly an online measurement device of the contact pressure of a circuit breaker contact. The online measurement device of the contact pressure of the circuit breaker contact comprises a pull rod, a connecting rod, a force sensor mounted at bottom of the pull rod, and a disc spring sleeved on the connecting rod; the connecting rod and the disc spring are arranged inside a cavity formed on an upper portion of the pull rod; and the force sensor is provided with a strain gauge. The online measurement device of the utility model has the advantages of simple structure, convenient operation, effective connection of an vacuum arc-extinguishing chamber and a circuit breaker mechanism, capabilities of converting pressure changes into voltage signals and accurately measuring the contact pressure as well as instantaneous opening and closing points of the contact, and improvement of accuracy of mechanical characteristic measurement of intelligent vacuum circuit breakers.
Description
Technical field
The utility model relates to the technical field of vacuum circuit breaker, especially a kind of on-line measurement device for contact of breaker contact pressure.
Background technology
In the market the contact pressure of institute's applying unit intelligent vacuum circuit breaker contact can't-on-line measurement, after can only having measured pressure in advance, again with in the data entry program, just branch, the seizure of chalaza just mainly are to calculate by Calculation Method simultaneously, cause The ultimate results accurate, influence the work of isolating switch.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of on-line measurement device of contact of breaker contact pressure is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of on-line measurement device of contact of breaker contact pressure, comprise pull bar, connecting link, be installed in the power sensor of pull bar bottom and be sleeved on dish spring on the connecting link, described connecting link and dish spring are arranged in the cavity of offering on pull bar top, and the power sensor is provided with foil gauge.
The beneficial effects of the utility model are: the utility model is simple in structure, easy to operate, vacuum interrupter effectively is connected with breaker mechanism, convert the variation of pressure to voltage signal, the contact pressure that can onlinely measure contact exactly reaches just branch, firm chalaza, has improved the accuracy of intelligent vacuum circuit breaker measuring mechanical characteristics.
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. pull bar, 2. connecting link, 3. power sensor, 4. dish spring, 5. foil gauge.
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 shows the formation relevant with the utility model.
The on-line measurement device of contact of breaker contact pressure as shown in Figure 1, comprise pull bar 1, connecting link 2, be installed in the power sensor 3 of pull bar 1 bottom and be sleeved on dish spring 4 on the connecting link 2, connecting link 2 is arranged in the cavity of offering on pull bar 1 top with dish spring 4, and power sensor 3 is provided with foil gauge 5.
The course of work of the present utility model: during combined floodgate, when the dynamic/static contact of vacuum arc-chutes rigidly connects when touching, connecting link 2 has produced reaction, along with the action of connecting link 2,4 distortion of dish spring have also produced pressure, and pull bar 1 is subjected to the effect of the power of dish spring 4, at this moment pressure sensitive appears in the foil gauge 5 on the power sensor 3, convert pressure to voltage signal, send on the display device, be convenient to operating personnel and check; During separating brake, pressure that foil gauge 5 is sensed disappears, and also can send voltage signal, thus can go out to contact pressure according to the measure of the change of magnitude of voltage and just divided, just chalaza.
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 this technology 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.
