Technical field
The utility model relates to circuit breakers monitoring device, especially vacuum circuit breaker over travel real-time monitoring device.
Background technology
Present vacuum circuit breaker is the characterisitic parameter being measured isolating switch by mechanical break-in tester mostly, what can record switch opens distance, over travel, on/off switch speed and branch wire time and spring etc., wherein just comprise over travel this, because over travel is directly connected to connecting-disconnecting function and the reliability of operation energy of vacuum circuit breaker, so this parameter is investigated as an important indicator.The over travel data of existing isolating switch, use loaded down with trivial details wiring and heavy equipment, testing cost is high, and process is complicated.
Utility model content
The purpose of this utility model is to provide a kind of vacuum circuit breaker over travel real-time monitoring device, more directly and more easily measures the over travel data drawing isolating switch, reduces and measures cost.For achieving the above object, the utility model is by the following technical solutions:
Vacuum circuit breaker over travel real-time monitoring device, comprises switch base, supporting base, displacement transducer, data line, display and the first connecting rod connected successively, second connecting rod, third connecting rod; Described first connecting rod and second connecting rod are straight-bar, described third connecting rod is bent rod, described first connecting rod is connected with switch base, the inflection point of described third connecting rod is positioned at above supporting base, described third connecting rod comprises front connecting lever and rear connecting lever, described front connecting lever is provided with an equivalent point, and described equivalent point place connection bit displacement sensor, displacement transducer connects display by data line.
Further, also comprise double leval jib, a pin is fixed at described equivalent point place, and described double leval jib one end and pin-hinges, the other end is connected with displacement transducer.
Wherein, the bending angle of described third connecting rod is 166 degree, and described equivalent point and the distance of supporting base are 0.385 times of front connecting lever length.
After adopting technique scheme, the utility model has following effect: this apparatus structure is simple, cost is lower and test result is accurate, vacuum circuit breaker is rotated by main shaft, drivening rod mechanism carries out on/off switch action, at equivalent point connection bit displacement sensor, by data transmission interface, directly over travel data can be read in real time over the display.
Accompanying drawing explanation
Fig. 1 is schematic front view of the present utility model;
Fig. 2 is that schematic diagram is looked on a left side of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.
Refer to Fig. 1, shown in Fig. 2, basis is novel discloses a kind of vacuum circuit breaker over travel real-time monitoring device, and in Fig. 1, solid line is original state figure, and dotted line is the view after vacuum circuit breaker is rotated to an angle by main shaft.This device comprises switch base 1, supporting base 2, first connecting rod 3, second connecting rod 4, third connecting rod 5, displacement transducer 6, data line 7, display 8.
First connecting rod 3 and second connecting rod 4 are straight-bar, third connecting rod 5 is bent rod, first connecting rod 3 is connected with switch base 1, the inflection point of third connecting rod 5 is positioned at above supporting base 2, the bending angle of third connecting rod 5 is 166 degree, and third connecting rod 5 comprises front connecting lever b and rear connecting lever a, and front connecting lever a is provided with an equivalent point B, the distance of equivalent point B and supporting base 2 is 0.385 times of front connecting lever b length, i.e. BE=0.385EF in figure.Equivalent point B place connection bit displacement sensor 6, displacement transducer 6 connects display 8 by data line 7.
Also comprise double leval jib 9 in the present embodiment, fix a pin 10 at equivalent point place, double leval jib 9 one end and pin 10 hinged, the other end is connected with displacement transducer 6.The use of double leval jib 9, can make the putting position of displacement transducer 6 more flexible, increase the space of laying.
Principle of the present utility model is as follows:
1. first connecting rod 3 is source moving part, and the initial position of third connecting rod 5 is ab, and when first connecting rod 3 clockwise direction is rotated, the final position of third connecting rod 5 is a'b', as shown in the dotted portion in Fig. 1.
2. the on/off switch operation of vacuum circuit breaker, third connecting rod 5 is made to move to a'b ＇ from ab, easily recording ab is that firm co-bit is now put, a'b ＇ is closing position, because the angle of this process is very little, arc length c near linear AA', arc length d near linear BB', and the arc length d that arc length c equals 2 times, we think that arc length c is the over travel of vacuum circuit breaker.
3. consider the restriction in space, directly measure arc length c, relatively inconvenience, so desirable arc length d is the excess of stroke equivalent length of 1/2nd.The length of namely getting BB' is the excess of stroke equivalent length of 1/2nd.
4. on third connecting rod 5, obtain equivalent point B, the bending angle getting third connecting rod 5 is as calculated 166 degree, the distance of equivalent point B and supporting base 2 is 0.385 times of front connecting lever b length, pin 10 is fixed in the above, another side and double leval jib 9 are linked together, make like this displacement transducer 6 can on/off switch with vacuum circuit breaker time, transfer plane and straight line motion to by approximate for the planar rotational movement of third connecting rod 5.
5. displacement transducer 6 is transmitted by data, can be transferred to above display 8 by the over travel data recorded, and display 8 is special device stand-alone developments for this reason, and can be arranged on panel, aspect user directly inquire about.The built-in embedded microprocessing unit of display 8, calculates the computing formula that the sensing data of collection is designed by professional software, and the over travel data being converted into reality show in real time, also by RS485/232, result of calculation are transferred to background system.
The above, be only the utility model preferably embodiment, is anyly familiar with those skilled in the art in the technical scope that the utility model discloses, the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
