Description
Technical field
The utility model relates to a kind of instrument of measuring vacuum contactor contact actuating length.
Background technology
Vacuum contactor is widely used in the electrical control of various kinds of equipment, as the electrical control of electric arc furnaces etc.; Because it is frequent that such vacuum contactor operation is switched, so the clearance between open contacts of vacuum contactor is less, in order to improve the electric life and the mechanical life of vacuum contactor; Equipment such as while electric arc furnaces have determined that the electric current of make-and-break of such vacuum contactor is very big, therefore vacuum switch tube adopts every phase two strings six connected mode also in such vacuum contactor, every have 12 vacuum switch tubes mutually, three-phase is totally 36 vacuum switch tubes, operating mechanism must move simultaneously in two vacuum switch tubes that require to connect when contactor closes a floodgate, its stroke must keep the consistance of height, the size of stroke will meet the technical standard of electrical control simultaneously, therefore the comparison of the vacuum switch tube contact travel of two series connection must be measured and do to the contact travel of this vacuum switch tube accurately, and whether the state that could judge vacuum contactor in view of the above is good.The contact actuating length is meant when contactor is in gate-dividing state in the vacuum switch tube, the distance in the vacuum switch tube between two contacts; Vacuum switch tube contact actuating length also depends on character, contact material and the requirement of withstand voltage thereof of dropout current under the rated voltage, service condition of switch, under different rated voltages, different types of vacuum switch tube clearance between open contacts can have different selections, but the size of stroke must meet the technical standard of vacuum contactor.
The measuring method of general probe of contactor stroke be optional 1 A on moving conductive rod, and optional another B on the contactor fixture then, mensuration A point are ordered the displacement difference of being walked with respect to B and can be determined when probe of contactor divide-shut brake position.
But there are following several big problems in the measurement of such vacuum contactor contact actuating length: 1. the contact actuating length is very little, only has about several mm, uses former settings A point and B point afterwards instrument such as employing vernier caliper to obtain the measured value precision not enough.2. contactor need be inverted measurement, is difficult to find the point of fixity B point of measurement, also is difficult to obtain the exact value of stroke according to traditional measuring method.3. such vacuum contactor actuating mechanism is many, and produced on-site load is heavy, and the vacuum packet that is difficult to dismantle contactor is come the measuring contacts stroke.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of instrument of measuring vacuum contactor contact actuating length, this instrument of utilization can conveniently be implemented the measurement of vacuum switch tube contact travel in the vacuum contactor, and improved measuring accuracy and efficiency of measurement, guaranteed the electric property of vacuum contactor.
For solving the problems of the technologies described above, the instrument that the utility model is measured vacuum contactor contact actuating length comprises slide bar, slide block, dial gauge, slide block set bolt and dial gauge set bolt, described slide bar is located on the vacuum contactor housing by the screw rod level, described slide block has chute and is located at described slide bar upper edge slide bar by chute and moves, described slide block vertically has through hole, described dial gauge fixed bar inserts in the through hole of described slide block, vertical respectively described slide bar of described slide block and dial gauge fixed bar have screw, and described slide block set bolt and dial gauge set bolt are twisted in the screw of described slide block respectively fixedly slide block and dial gauge position.
Because the utility model is measured the instrument of vacuum contactor contact actuating length and has been adopted technique scheme, be that slide bar is located on the vacuum contactor housing by the screw rod level, slide block has chute and is located at slide bar upper edge slide bar by chute and moves, slide block vertically has through hole, the dial gauge fixed bar inserts in the through hole of slide block, vertical respectively slide bar of slide block and dial gauge fixed bar have screw, and slide block set bolt and dial gauge set bolt are twisted in the screw of slide block respectively fixedly slide block and dial gauge position.This instrument can conveniently be implemented the measurement of vacuum switch tube contact travel in the vacuum contactor, and has improved measuring accuracy and efficiency of measurement, has guaranteed the electric property of vacuum contactor.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the utility model measurement vacuum contactor contact actuating length instrument,
Fig. 2 measures the synoptic diagram of vacuum contactor contact actuating length for this instrument.
Embodiment
As shown in Figure 1, the instrument that the utility model is measured vacuum contactor contact actuating length comprises slide bar 1, slide block 2, dial gauge 3, slide block set bolt 5 and dial gauge set bolt 4, described slide bar 1 is located on the vacuum contactor housing 9 by screw rod 11 levels, described slide block 2 has chute and is located at described slide bar 1 upper edge slide bar 1 by chute and moves, described slide block 2 vertically has through hole, described dial gauge 3 fixed bars 31 insert in the through hole of described slide block 2, vertical respectively described slide bar 1 of described slide block 2 and dial gauge 3 fixed bars 31 have screw, and described slide block set bolt 5 and dial gauge set bolt 4 are twisted in the screw of described slide block 2 respectively fixedly slide block 2 and dial gauge 3 positions.
As shown in Figure 2, certain vacuum switch tube that is in series 6 contact stretches out contactor housing 9 by gangbar 61 and passes through outer link 62 and connects in the vacuum contactor, when vacuum contactor contact actuating length is measured, the slide block 2 of this instrument is moved to gangbar 61 places of vacuum switch tube 6 contacts of vacuum contactor along slide bar 1, tighten slide block set bolt 5 and dial gauge set bolt 4 fixedly slide block 2 and dial gauge 3 positions, the A point of dial gauge 3 sounding rods 32 contact outer link 62, record dial gauge 3 readings this moment, vacuum contactor is closed a floodgate, vacuum switch tube 6 closings of contact, gangbar 61 drives outer link 62 and moves up, read dial gauge 3 numerical value this moment, then the difference of these vacuum switch tube 6 closing of contact dial gauges, 3 readings and vacuum switch tube 6 contacts disconnection dial gauge 3 readings is the actuating length of contact; Unclamp slide block set bolt 5 then, slide block 2 is moved to the gangbar place of another vacuum switch tube contact of vacuum contactor along slide bar 1, tighten slide block set bolt 5, the B point of dial gauge 3 sounding rods 32 contact outer link 62, repeat above-mentioned measuring process, can obtain the actuating length of this vacuum switch tube contact.So can be convenient for measuring the actuating length of the vacuum switch tube contact that respectively is in series in the vacuum contactor, and the data that record can be compared, as there are differences then and need implement structural adjustment, to satisfy the electric property of vacuum contactor.
