Description
Technical field
This utility model relates to a kind of measuring instrument, particularly to a kind of instrument for measuring middle-placed switch cabinet handcart dynamic/static contact insertion depth.
Background technology
System internal phase continues and there occurs that a few cause middle-placed switch cabinet handcart dynamic/static contact insertion depth is not enough (20mm-25mm) in recent years, causes the accident that switch cubicle burns.
Owing to middle-placed switch cabinet is full-closed structure, in current system, there is no method and the instrument measuring insertion depth effectively, fast, accurately.Summing up apparently, current existing measuring method mainly has two kinds and is all the indirect method of measurement.
Method 1:
Being coated with vaseline on static contact, the mark lengths stayed by vaseline after measuring dynamic and static contact, as insertion depth.This scheme by vaseline smear number, the uniformity smeared and measure time error and affected very big, can only about measure handcart dynamic/static contact insertion depth.
Method 2:
By measure middle-placed switch cabinet handcart shake into, shake out the change of relative position, calculate handcart dynamic/static contact insertion depth.This method is affected very big by measurement error, handcart each several part mismatch error, also can only about measure the degree of depth that handcart dynamic/static contact inserts.And our technical standard is 20mm-25mm, bigger error largely effects on the accuracy of measurement.
In order to solve the problems referred to above, CN204988189U patent discloses a kind of laser without contact middle-placed switch cabinet handcart contact travel tester, comprising: laser range sensor device, is used for being placed on outside handcart, detects handcart displacement, and generate distance signal；Contact detection device, is used for detecting handcart moving contact, static contact contact condition, and sends triggering signal when contact；Processor, it is connected with described laser range sensor device, contact detection device, when described processor receives described triggering signal, the distance signal that distance test device described in described processor record generates, and calculate the degree of depth of moving contact insertion static contact；Input/output unit, and the degree of depth of the moving contact insertion static contact of described processor calculating gained.
Although technique scheme has the advantages such as fast, little, the dependable performance of volume of range finding, but its shortcoming is the most clearly, essentially consists in: laser is impulse ejection, and general absolute precision is relatively low, additionally, its manufacturing cost is higher.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of middle-placed switch cabinet handcart dynamic/static contact insertion depth measuring instrument.
