Description
Technical field
This utility model relates to carbon slipper sealing property technical field, is specifically related to a kind of carbon slipper airtight examination of many gas circuits
Test platform.
Background technology
Carbon slipper as the electric power drainage component of electric locomotive and high ferro power, carbon slipper directly contact with contact net lines into
Row power taking.Carbon slipper is arranged on the top of pantograph, and when needs carry out power taking to locomotive, pantograph " rising bow ", by carbon slipper
Raise and abut on contact net lines.
During actually used, once pantograph is clashed into by the external world, as slungshot, the impact of bird or with contact net lines it
Between wear and tear, it will cause the breakage of pantograph self, may be wound around with electric wire after pantograph breakage, to whole machine
Properly functioning the bringing of car has a strong impact on.
In order to the very first time finds that pantograph is impaired, prior art is offered at carbon slipper center along its length
Having air flue cavity, in use, one end of air flue cavity is blocked, and the other end is connected with pantograph, and pantograph sets
Having aerating device, when carbon slipper carries out power taking on contact net lines, aerating device makes the air chamber of pantograph and carbon slipper
Road keeps air pressure consistent；Once carbon slipper is damaged, and owing to will produce draught head between carbon slipper and pantograph, pantograph fills
The monitoring system putting inside can allow pantograph " drop bow ", makes carbon slipper separate with electric wire, thus Accident prevention occurs.
After pantograph completes, in fact it could happen that the situation that self air-tightness is bad, i.e. when the mistake of pantograph " rising bow "
Cheng Zhong, owing to pantograph self gas leakage is serious, causes pantograph detecting system to take for pantograph and has occurred and that damage, the most just
The action of " rising bow " cannot be completed.
Accordingly, it would be desirable to a kind of carbon slipper airtightness test table of design, the air-tightness of carbon slipper self is detected.
Prior art provides the air tightness detection equipment of a kind of carbon slipper, this equipment arranges single carbon slipper inspection
