Abstract
The utility model relates to a universal clamp which is suitable for the installation of a plurality of sensors on a mechanical characteristic testing instrument of a circuit breaker. The clamp is provided with fixing plates for sensors, a fixing rod and a connecting rod, wherein one end of the fixing rod is fixedly connected with a U-shaped clamping head, and the other end of the fixing rod is connected with one end of the connecting rod through a locking hinge; the other end of the connecting rod is connected with the fixing plates for the sensors. In this way, a linear displacement sensor body or an angular displacement sensor body can be arranged on the corresponding fixing plate, the angle of the locking hinge arranged between the connecting rod and the fixing rod is regulated according to needs, the U-shaped clamping head is utilized to fix the fixing rod on the body of the circuit breaker, and thus a sensing head of the sensor can be engaged with a corresponding device to be tested on the circuit breaker. The utility model has the advantages of flexible operation and convenient installation and can surely ensure the accuracy of testing results.
Description
Technical field
The utility model relates to a kind of breaker mechanic property tester sensor sectional fixture, the general-purpose anchor clamps that especially a kind of suitable multiple sensors is installed.
Background technology
Previous switch (isolating switch) testing mechanical characteristic is recorded in various test signals on the light sensitive paper by light oscillograph, determines the parameter of switch by reading oscillogram.Along with the development of chip technology, the oscillographic breaker mechanic property tester of simulation light has appearred.This quasi-instrument has realized that the digitizing of test parameter shows.But after the new standard IEC62271-100 (its domestic version GB1984-2003) of switching characteristic test put into effect, existing tester all can not satisfy the test request of new standard to isolating switch multinomial characterisitic parameter, especially mechanical characteristic.
For this reason, applicant has been developed a kind of breaker mechanic property tester that can satisfy the new standard test request.This tester contain need with isolating switch device to be tested---sensor such as linear displacement that isolating switch is connected, angular displacement.
The utility model content
The purpose that the utility model is wanted is: at the user demand of above-mentioned suitable new standard tester, propose a kind of breaker mechanic property testing sensor general-purpose anchor clamps that can satisfy the multiple sensors installation requirement simultaneously.
Reach above purpose in order to solve, breaker mechanic property testing sensor general-purpose anchor clamps of the present utility model contain sensor fixation plate, also contain fixed bar and connecting link, one end of described fixed bar is fixed with the U-shaped chuck, the other end is connected by locking hinge with an end of connecting link, and the other end of described connecting link links to each other with fixed head.
Like this, linear displacement or angular displacement sensor body can be placed on the corresponding fixed head, regulate the angle of hinge between connecting link and the fixed bar more as required, and fixed bar is fixed on the breaker body by the U-shaped chuck, corresponding device under test is connected and gets final product on the sensing head that makes sensor and the isolating switch, use flexibly, easy for installation, can guarantee precision of test result conscientiously.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is used for the structural representation of linear displacement transducer for embodiment of the utility model.Each piece mark is among the figure: 1. moving contact, 2. universal joint, 3. slide bar, 4.

Fig. 2 is used for the structural representation that angular displacement sensor is installed for Fig. 1 embodiment.Each piece mark is among the figure: 3 '. isolating switch main shaft, 4 '. and angular displacement sensor body, 5 '. herringbone fixed head, 6. gimbal suspension, 7. connecting link, 8. locking hinge, 9. fixed bar, 10. gimbal suspension, 11.U clevis, 12. lock(ing) bolts, 13. breaker bodies.
Embodiment
Embodiment one
The breaker mechanic property testing sensor general-purpose anchor clamps of present embodiment are used for hookup wire morpheme displacement sensor, as shown in Figure 1, mainly form by sensor fixation plate 5, gimbal suspension 6, connecting link 7, locking hinge 8, fixed bar 9, gimbal suspension 10, U-shaped folder 11, clamping screw 12.Wherein, one side of U-shaped folder 11 relies on lock(ing) bolt 12, whole anchor clamps can be clamped to the correct position of breaker body 13.One end of fixed bar 9 is connected by locking hinge 8 with an end of connecting link 7, the other end is connected with U-shaped chuck 11 by gimbal suspension 10, the other end of connecting link 7 is connected with fixed head 5 by gimbal suspension 6, all promptly lock after being connected the locking of locking hinge, and therefore angle each other can be regulated the back locking as required.
Like this, Linear displacement transducer body 4 can be placed on the fixed head 5, slide bar 3 is connected by universal joint 2 with moving contact 1 up.
Facts have proved,, can guarantee the coaxiality error≤0.2mm between moving contact axis and slide bar axis, and sensor body and breaker body should not produce relative displacement in test as long as install suitably.
Embodiment two
The general-purpose anchor clamps basic structure of present embodiment is identical with embodiment one, be used for the established angle displacement transducer, its difference be angular displacement sensor 4 ' to be fixed on the cross section be lambdoid fixed head 5 ' one side, its sensor ends is connected with isolating switch main shaft 3 ' on the breaker body 13.
In a word, breaker mechanic property testing sensor general-purpose anchor clamps of the present utility model use flexibly, and are easy for installation, are applicable to the installation of multiple sensors, help to guarantee precision of test result.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
