Description
Technical field
The utility model relates to high voltage substation field, particularly relates to 10kV switch cart contact stroke special measurement instrument.
Background technology
When changing 10KV switch cubicle, all there is loose contact situation in its main transformer 10KV side switch of switch cabinet dolly contact and bus connection switch dolly static contact, even there is the situation not having to contact, if its switch cart moving contact and bus connection switch dolly static contact contacting travel undesirable, will loose contact be caused, contact temperature can be caused when load is larger to raise rapidly.Temperature is too high can accelerate the aging of its surrounding insulation material.Even there is the aging breakdown phenomenon of its surrounding insulation material.There is singlephase earth fault, if fault spread will burn switch cart even switch cubicle, cause large area blackout.Therefore, in installation process, know its switch cart contact situation (technical requirement: contacting travel is 15-25mm) accurately extremely important, it is particularly important how to survey its contacting travel accurately.
Measuring method conventional at present comprises: (1), by the indirect method of measurement, measures the length of its moving contact and static contact respectively, measures the length of switch cabinet simultaneously, is formed by calculating its contact by above-mentioned several numerical value.The defect adopting this kind of method to measure is, need repeatedly manual measurement and then calculate, repetitive measurement exists error, and cumulative errors can cause the result calculated.(2) embrocate auxiliary agents (as: conductive paste, butter etc.) at its static contact outside surface, measure its contact trace length and obtain contacting travel.Because trajectory sharpness is not high, so there is larger error in measuring process.
Utility model content
The purpose of this utility model is the problem measuring inconvenience for existing switch of switch cabinet dolly moving contact and bus connection switch dolly static contact contacting travel, there is provided one can be convenient and swift, the efficient instrument that its contacting travel is measured, thus improve the contact strength of moving contact and static contact, ensure the security that equipment runs.
In order to realize above-mentioned technical characteristic, the purpose of this utility model is achieved in that 10kV switch cart contact stroke special measurement instrument, it comprises dip stick, it also comprises rear sight base, one end of dip stick is inserted in the staff guage hole of rear sight base, and being fixed in rear sight base by holding screw, the other end of dip stick is set with vernier slide block, and vernier slide block is fixedly mounted in vernier snap ring by screw.
Described rear sight base comprises sleeve and locating ring, sleeve is processed with oil hole and screw hole, is processed with staff guage hole in center.
Described vernier slide block can slide on dip stick.
Described vernier slide block is provided with scale mark match with the scale mark on dip stick.
The utility model has following beneficial effect:
In use, rear sight base is arranged in the endoporus of moving contact by sleeve, carry out end face location by locating ring simultaneously, then moving contact and static contact are connected, moving contact is inserted in the endoporus of static contact, thus make vernier calliper articulating contact the end face of static contact, now drive vernier slide block slides by vernier snap ring on dip stick, when moving contact to contact after connection terminates with static contact, taken out from moving contact by whole measurement mechanism, the data read on dip stick are the contacting travel between moving contact and static contact.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Fig. 2 is the utility model rear sight base structural representation.
In figure: rear sight base 1, holding screw 2, dip stick 3, vernier snap ring 4, vernier slide block 5, screw hole 101, oil hole 102, sleeve 103, locating ring 104, staff guage hole 105, screw 401, scale mark 501.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1,10kV switch cart contact stroke special measurement instrument, it comprises dip stick 3, scale above accurately can be read by dip stick 3, it also comprises rear sight base 1, one end of dip stick 3 is inserted in the staff guage hole 105 of rear sight base 1, and be fixed in rear sight base 1 by holding screw 2, the other end of dip stick 3 is set with vernier slide block 5, vernier slide block 5 is fixedly mounted in vernier snap ring 4 by screw 401, directly can measure the contacting travel between moving contact and static contact by being slidably matched between vernier slide block 5 and dip stick 3.
As shown in Figure 2, described rear sight base 1 comprises sleeve 103 and locating ring 104, sleeve 103 is processed with oil hole 102 and screw hole 101, is processed with staff guage hole 105 in center.By screw hole 101, holding screw 2 is installed and dip stick 3 can be fixedly mounted on rear sight base 1 inside.Lubricating oil can be added to rear sight base 1 inside by oil hole 102, thus be convenient to dip stick 3 and carry out slidable adjustment therein.
Further, described vernier slide block 5 can slide on dip stick 3, by sliding thus facilitating the measurement of its stroke.
Further, described vernier slide block 5 is provided with scale mark 501 and matches with the scale mark on dip stick 3, thus be convenient to the reading of scale.
Advantage of the present utility model:
Adopt the mode directly measured, significantly provide the contacting travel between moving contact and static contact, improve measuring accuracy, effectively avoid because measuring accuracy is not high, the dynamic/static contact loose contact phenomenon caused occurs, and even discontiguous situation occurs.To ensureing that good effect is played in the safe operation of electrical equipment.Avoid the generation of operational outfit damage accident.
Above-described embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, to the novel any amendment made of this practical machine and change, all fall into protection domain of the present utility model.
