Description
Technical field
The invention belongs to a kind of contact of breaker survey tool, more particularly to a kind of breaker dynamic/static contact contact
Survey tool.
Background technology
Existing contact of breaker pressure measxurement is generally obtained indirectly by calculating touch spring power, and touch spring is closing a floodgate
After deform, deformation produces pressure extrusion moving contact so that moving contact and static contact are compressed.But touched because different model breaker is dynamic
Header structure and motion mode are different, and the moving contact for example having is double spring, and two rows spring deflection is different, and due to
, there is contact height difference, also result in camber of spring difference, and measure in practice in the welding technique level limitation of processing side
Spring deflection inside contact needs to calculate out spring deflection by measuring breaker over-travel data, then by excess of stroke data,
The pressure calculation contact pressure produced by camber of spring, result in by spring force to calculate that contact pressure has larger accumulation
The variety of problems such as error.
The content of the invention
Present invention technical problem present in solution known technology provides one kind and works simple and efficient efficient, and data are straight
See, the breaker dynamic/static contact contact survey tool that error is substantially reduced.
The present invention is adopted the technical scheme that to solve technical problem present in known technology：It includes film pressure
Force snesor, also includes handle, the thimble rod of rectangular shaped post of a long cylinder bodily form；In one end of the thimble rod
For tack.The other end is a conical points, and has one to can be inserted into the diaphragm pressure sensor at the center of the thimble rod
Through hole；Have a through hole between the upper and lower ends of described handle, and the shape size in the hole of upper end for can just will described in
Diaphragm pressure sensor is inserted, and the shape size of lower stomidium is that just can insert the thimble；And in the length of the handle
Tubular side has an available trip bolt that the thimble inserted in the handle is compressed to the hole reinforced.
The present invention has the advantages and positive effects of：After breaker closing, can quickly it be measured by this set instrument
Contact pressure.The present invention only has a set of thimble and handle and a standard soket head cap screw, and cost is low, and simple and convenient assembly is quick, makes
With safety, by original cumbersome measurement and computational short cut, the contact force that moving contact contacts surface with static contact is directly measured so that
Work is simple and efficient efficiently, and data are directly perceived, and error is substantially reduced, and greatly improves measurement accuracy and speed.And thereby further may be used
To adjust improvement circuit breaker parameters by analyzing the pressure data of each contact measured, provide more directly perceived for circuit breaker design
Effective foundation.

Embodiment
For present disclosure, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinate accompanying drawing detailed
It is described as follows：
As Figure 1-3, the thimble rod 1 of the handle 2 of the long cylinder bodily form, rectangular shaped post；It is flat in one end of thimble rod 1
Head.The other end is a conical points, and has at the center of thimble rod 1 through hole of a pluggable diaphragm pressure sensor 4；In handle
There is a through hole between 2 upper and lower ends, and the shape size in the hole of upper end is just can insert diaphragm pressure sensor 4,
The shape size of lower stomidium is that just can insert thimble 1；And there is one to can use tightly in the side of the long cylinder bodily form of handle
Gu screw compresses the thimble 1 inserted in handle 2 in the hole 3 reinforced.
As Figure 4-Figure 6, the larger oblong aperture one end of handle 2 is inserted into the tack one end of thimble 1, with trip bolt insert band spiral shell
Line counterbore 3 is tightened, and thimble 1 leans out distance and can adjusted according to actual use situation；There is circular membrane the one end of diaphragm pressure sensor 4
This end of piece is measurement end, the circular one end of pressure sensor 4 is put into from the smaller oblong aperture one end of handle 2, from the tapered end thereof of thimble 1
Half of circular diaphragm is leant out in oblong aperture；By assemble deeply closed a floodgate with upper-part after breaker contact system, thimble 1
Tapered end thereof firmly pushes handle 2 after running into the dynamic and static contact 5,6 of breaker closing, and the tapered end thereof of thimble 1 squeezes into circuit breaker closing
Dynamic and static contact 5,6 points are opened behind gap between the dynamic and static contact 5,6 closed, by the test of diaphragm pressure sensor 4 to dynamic and static contact
5th, the place contacted during 6 closure, withdraws from thimble 1, and the dynamic and static contact 5,6 of breaker is closed, and now can directly measure contact
Pressure, treats firmly to push handle 2 after the completion of pressure measxurement, again squeezes between dynamic and static contact 5,6 thimble 1, withdraw from film pressure
Thimble 1 is withdrawn from after force snesor 4.
