Description
Technical field
The present invention relates to a kind of surveying instrument, in particular to a kind of instrument for measuring mid-cabinet handcart dynamic/static contact depth of penetration.
Background technology
In succession there occurs a few cause mid-cabinet handcart dynamic/static contact depth of penetration deficiency (20mm-25mm) in recent years in system, cause the accident that switching cabinet burns.
Owing to mid-cabinet is full-closed structure, in current system, there is no the method measuring depth of penetration effectively, fast, accurately and instrument. Summary be it seems, current existing measuring method mainly contains two kinds and be all indirect inspection method.
Method 1:
Being coated with Vaseline on static contact, the vestige length stayed by Vaseline after measuring dynamic and static contact, as depth of penetration. This kind of scheme by Vaseline smear number, the homogeneity smeared and when measuring the impact of error very big, can only approximately measure handcart dynamic/static contact depth of penetration.
Method 2:
By measure mid-cabinet handcart shake into, shake out the change of relative position, calculate handcart dynamic/static contact depth of penetration. This kind of method coordinates the impact of error very big by measuring error, handcart each several part, also can only approximately measure the degree of depth of handcart dynamic/static contact insertion. And our technological standard is 20mm-25mm, bigger error affects the accuracy of measurement greatly.
In order to solve the problem, CN204988189U patent discloses a kind of laser without contact mid-cabinet handcart contact stroke tester, comprising: laser range sensor device, for being placed on outside handcart, detect handcart miles of relative movement, and generate range signal; Contact detection device, for detecting handcart moving contact, static contact contact condition, and sends triggering signal when contacting; Treater, it is connected with described laser range sensor device, contact detection device, when described treater receives described triggering signal, the range signal that distance test set described in described processor for recording generates, and calculate the degree of depth setting out contact insertion static contact; Input-output unit, and the degree of depth of the dynamic contact insertion static contact of described treater calculating gained.
The advantages such as range finding is fast, volume is little although technique scheme has, dependable performance, but its shortcoming is also clearly, is mainly: and laser is impulse ejection, and general absolute precision is lower, and in addition, its manufacturing cost is higher.
