Description
Technical field:
The utility model relates to shutter movable contact contact depth and oscillating quantities in the goat on railway switch
The measurement of data is related to a kind of movable contact contact depth calibrator by it.
Background technique:
Goat on railway switch is one of the important equipment for affecting track switch lane change, therefore it is required that turn-out track inboard installation
Inspection and technical requirements be it is very high, by its be in goat shutter movable contact contact depth DATA REASONING, by
The status overhauled at present: according to automatic lid actuator technical requirements, " trailing contact ring is connected two sides static contact fingers and is started to movable contact
The depth that ring squeezes into contact strip should be not less than 4mm ", and it is excessively shallow such as to contact depth, and it is inadequate to will cause contact pressure, easily cause because
The switch breakdown of contact poor contact occurs, and such as contact depth is too deep, can make contact pressure is excessive not meet requirement, simultaneously
Also can make to check that column tilt angle increases, so that movable contact and the break of two sides is contacted depth also unbalanced, cause movable contact with
Break two sidewalls frictional force increases, and eventually leads to the failure that contact does not get off, and general scene internal control is between 4-6mm；And
Another technical parameter " pulls movable contact with hand, oscillating quantity is not more than 3.5mm ", and excessive will result in of the oscillating quantity connects
Point contact bad error occurs, therefore movable contact contact depth and oscillating quantity parameter are just particularly important.But at present with
Upper two values are in maintenance process, since online equipment is cannot to use the measurement work of metal material under electriferous state
Tool, such as the tools such as vernier caliper measure, and can even measure, and can also have very big measurement error, therefore scene
