Description
Technical field：
This utility model is related to a kind of suitable for the embedded field structure of hydrogenerator temperature rise sensing device.
Background technology：
In hydrogenerator unit, magnetic pole and stator core friction, electromagnetic consumable increases, unit cooling effect is poor also has
Reason is installed and produces dither loss the reason for all can cause magnetic pole temperaturing lifting abnormality, conventional magnetic pole temperature rise using infrared measurement of temperature or
The traditional approachs such as person's platinum resistance thermometer sensor, thermometric, have the disadvantage that measured value is inaccurate, and temperature element is also easily damaged, and are badly in need of a kind of being suitable for
It is applied in field structure in hydrogenerator temperature rise sensing device.
The content of the invention：
The purpose of this utility model be by using the new embedded field structure of hydrogenerator temperature rise sensing device,
Ensure to accomplish constantly to monitor in the middle of unit operation, once there is the too high phenomenon of temperature rise, can be by embedded pole coil
Sensing device to remote computer and alarm, be easy to search the position judgment failure cause of temperature rise in time, can have in time
What is imitated avoids the too high potential safety hazard for causing of magnetic pole temperature rise.The technical solution of the utility model is：A kind of hydrogenerator water
The embedded field structure of turbine generator temperature rise sensing device, by pole core assembling (1), pole coil (2), sensing device (3),
Magnetic pole shell feed plate (4) is constituted, and sensing device (3) is embedded in pole coil (2), then pole coil (2) is enclosed within into pole core
In assembling (1), sensing device (3) and pole coil (2) are fixed on pole core assembling (1) by magnetic pole shell feed plate (4),
Sensing device (3) is connected with terminal box and passes the signal along to remote computer.
Technique effect：In hydrogenerator unit, due to producing machinery with stator core in the operation of magnetic pole Rig up error
Friction, the temperature of magnetic pole can become very high, ultimately cause unit operation accident, or exist than larger between magnetic pole and yoke
Air gap, higher hamonic wave air gap surface produce electromagnetic consumable, or unit cooling effect it is poor, install reason produce dither damage
The reason for consumption all can cause magnetic pole temperaturing lifting abnormality, magnetic pole long-time operation in high temperature easily causes the fracture of magnetic pole connecting part position,
And produce electric arc and burn out the interruption of services such as insulation, rotor ground fault, the stable operation to unit brings potential safety hazard.Hydraulic generator
The embedded field structure of machine temperature rise sensing device, in each position of coil very sensitive temperature sensing device is embedded in,
Sensor probe, sensing optic cable can be effectively protected to walk line groove by pole insulation plate and extend by distinctive coil recess
To outside magnetic pole, finally it is connected with remote computer.The temperature rise of magnetic pole in unit operation can be by remote computer constantly
Monitoring, once find that Temperature numerical is too high can process in time, it is to avoid there is interruption of service so as to affect whole unit in magnetic pole.
