Description
Technical field
The present invention relates to electrical generator fields, more particularly to a kind of generating set signal draws switching device.
Background technology
The major bearing of power station generator group, such as thrust bearing, guide bearing are run in closed environment；Generator
Various sensors in group inside such as measure the temperature sensor of thrust bearing, guide bearing, and measure generator's motor shaft vibration
Vibration ferry-boat sensor of ferry-boat amount etc. is required for the parameter signal for running set state from closed environment to draw.These letters
Number part is the safe and stable operation and service life of the accuracy, stability of these signals concerning unit for generator protection.
Power station generator group signal ejector need to meet the following conditions due to being mounted on unit wall：
1, due to will produce bigger vibration in unit running process, which must be shockproof；
2, since the rotation of big axis in unit running process can drive internal oil stream impact signal cable, the device necessary
Impact resistance protection signal cable, impact of the reduction oil stream to signal cable can eliminate the possibility of signal cable broken string very well
Property；
3, in operation due to unit, the general internal pressure for having 0.3~0.5MPa, the device must be pressure-resistant, sensor
Signal must solve the problems, such as long term seal when being drawn from the device；
4, since the signal in generating set is in highfield and magnetic field environment, when adapting system draws sensor signal
The shielding that sensor draws signal cable cannot be destroyed, prevents interference signal from entering in test system；
5, since unit ambient enviroment is usually moister, narrow space, the necessary antirust of the device, structure is reasonable, convenient
Site operation.
At present major part power station generator group signal ejector using：The trepanning on unit wall, around hole
Four screw holes for being fixed on the socket of needle quick connector in trepanning are set, and socket utilizes sealing by screw
Gasket is mounted on screw hole to which sealing is fixed on unit wall, and socket is using the signal cable in soldering and welding unit, needle
The plug of quick connector is matched with socket, and the contact pin of plug is using the signal cable outside soldering and welding unit.Such knot
Structure is designed since oil stream generates the signal cable arranged in unit very big under the drive of the big axis of unit when unit runs at high speed
Impact, by four screws come fixed pin quick connector, fixed function power cannot meet unit vibration and unit high speed
Impact of the oil stream to signal cable and connector connection part position；Using the sealing means of four screw in compression gasket seals, due to
Pressing force is smaller, in unit During Process of Long-term Operation, the phenomenon that there are oil leaks；Needle quick connector is using external welding sensing in soldering
Device signal cable causes scene to deposit difficulty of construction big.
The integration signal ejector as shown in Figure 1 used to solve the above-mentioned problems, does not cut off sensor
Signal cable shields, and internal sensor signal cable is extended, and by the way of being welded with unit wall, is realized with cable jacket
The sealing of generating set signal device is drawn.But there are certain drawbacks for such structure design, it is all golden in generator
Under conditions of category, it is difficult to ensure that signal cable crust is not scratched, as long as sensor signal cable outer layer ruptures, entire sealing dress
Setting will be ineffective, and to also very troublesome with repair later, sensor needs after the time that generating set runs 1 year or so
When carrying out effect to sensor, the problems of integration will expose, and be very numb by the dismounting of integrated sensor
It is tired and difficult.
