Abstract
The invention relates to a device for detecting pressure between contacts of a disconnecting switch. The device comprises a base, a balance plate, a detecting head, a balance center, a micro change-over switch, an indicating lamp, a crank, a screw rod, a spring, a spring base, a dial, a pointer and the like in a combining-connecting mode. According to the device, the lever principle is used, pressure generated between the contacts is transmitted to the standard spring, and the detected pressure between the contacts is read through the dial and the pointer. By replacing the detecting head of the detecting device, contacting pressure between the contacts in various contact modes of a disconnecting switch can be detected, the contacting reliability of outgoing product contacts is guaranteed, and when the disconnecting switch is subjected to on-site mounting adjusting and periodic maintenance, contacting pressure between the contacts can be detected conveniently and accurately.
Description
Technical field
The present invention relates to a kind of electrical equipment pick-up unit, particularly pressure-detecting device between a kind of isolation switch contact.
Background technology
In the manufacture of disconnector, within the limits prescribed whether the contact between contact, just judged according to establishing the physical dimension that provides in chronogram and the force characteristic of contact pressure spring.In Product Assembly, when physical dimension changes or when the force characteristic of contact pressure spring changes, whether the contact between contact often changes cannot be judged.Especially disconnector moves after the several years out of doors, because heating and the factor such as physical environment are easy to cause the inefficacy of contact pressure spring, thereby cause reducing of contact Contact pressure, and operation department is when maintenance, normally with spring balance, carry out detection contact Contact pressure, in operation not only inconvenience but also inaccurate of detection contact Contact pressure in this way during site examining and repairing, thus the problem of its existence can not be found in time, thereby buried hidden danger to the safe operation of disconnector.
Summary of the invention
The object of the present invention is to provide a kind of pick-up unit that can easily and accurately detect isolation switch contact Contact pressure.
Technical solution of the present invention is: pressure-detecting device between a kind of isolation switch contact, it is characterized in that it is by pedestal, balance plate, detecting head, the scale heart, inching conversion switch and pilot lamp, crank, screw rod, spring and spring base, the component combination such as index dial and pointer connects and composes, two detecting heads are outwards arranged on respectively the top of pedestal and balance plate, pedestal and balance plate are set up in parallel, the scale heart is located on pedestal and its top is against on balance plate, bottom at pedestal is provided with spring spool, in spring spool, be provided with spring and the spring base that is positioned at spring end, one end is stretched into spring spool and is threaded with spring base through spring through balance plate and pedestal with the screw rod of crank, on spring base, be provided with pointer, the notch that pointer arranges from spring housing barrel extend out to outside spring spool, spring spool outer wall notch place is provided with index dial, the bottom of pedestal is provided with inching conversion switch, the bottom of balance plate is provided with the set screw that regulates inching conversion switch.
Described pedestal and balance plate bottom are also provided with banking pin.
The present invention utilizes lever principle, the pressure producing is delivered on standard spring, and reads the detected pressures between contact by index dial and pointer between contact.Also can change by changing the position of the scale heart (fulcrum) no-load voltage ratio of moment, thereby change sensing range.
Feature of the present invention is: by the probe of substitution detector more, can detect the contact between the contact of the various contacting patterns of disconnector.Guarantee the to dispatch from the factory reliability of product contact contact, also makes that disconnector is carried out to scene and installs and adjust and during prophylactic repair, can facilitate and the contact between detection contact exactly.To adjust in time, make contact between contact all the time in the scope requiring.Guarantee that disconnector is operating safe, reliable.

Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
As shown in the figure, the present embodiment has provided a structure that range is " I ", can detect 500N with interior contact Contact pressure.Balance plate 2 is through being set up in parallel with pedestal 3, and the scale heart 4 is arranged on the ad-hoc location between balance plate and pedestal.Crank 7 is fixedly connected with screw rod 11, and screw rod is through balance plate and pedestal, and its end is threaded with the spring base 16 in being located at spring spool 14.Spring 12 is positioned at spring spool.Spring base is provided with pointer 17, and it is stretched out by the notch on spring housing barrel, is positioned on the index dial 15 that is located at spring spool outer wall.Inching conversion switch 10 with a pair of normally opened contact and a pair of normally closed contact is arranged on base bottom, and its conversion stroke is regulated by the set screw 8 being arranged on balance plate.Inching conversion switch is also connected with switch indication light 13, in order to the conversion of indicator cock.Position relationship between balance plate and pedestal is limited by banking pin 9.Detecting head 1 is arranged on the top of balance plate and pedestal.Between crank and balance plate, be also provided with stop-motion seat 5 and slide plate 6.
Before measurement, first with banking pin, the position of balance plate and pedestal is limited, make balance plate and pedestal keep substantially parallel state, now, the reading of indication nail on index dial should be 0.Then adjust position the locking just changed inching conversion switch to two pair contact.By adjusting set screw, can change the action switching time of inching conversion switch." S " size of finally adjusting detecting head 1, makes it equal the physical size of tested contact.
During measurement, detecting head is inserted in tested contact and be placed in wish and survey position, make two detecting head maintenance levels, then rotate along clockwise direction crank, now, the screw rod being fixed together with crank is also together along clockwise rotating, and band flexible spring seat moves along spring spool inwall, the compressed generation pressure of spring.Now, stop-motion seat is pressed in vee notch and can not rotates, and because the slide plate of establishing is thereon to be made by the little material of friction factor, the rotary resistance of hand crank is reduced more freely.When spring base moves, the pointer being integrated with spring base also moves along spring spool notch, has the effect of guiding simultaneously, guarantees that spring base is not with bolt rotary.Be rotated further crank, it is compressed that spring continues, the moment that directly causes the conversion of switch indication light light the crank that stops operating, now, pointer aligns with certain scale of index dial, this reading is the contact value between contact.
By the probe of substitution detector more, can detect the contact between the contact of the various contacting patterns of disconnector.
