Abstract
The utility model provides a kind of Generator Stator Cooling water and changes water overflow mechanism, including overflow pipe, on cooling water blow-off line, installs air hose at the top of overflow pipe additional.By installing overflow pipe additional before the drainage door of stator cooling water case, eliminate the occurrence of causing Generator Stator Cooling water to cut off the water supply during stator cooling water changes water, reach the essential safety that generator unit stator cold water changes water process.
Description
Technical field
The utility model is related to generator cooling technology field, particularly relates to a kind of Generator Stator Cooling water and changes water overflow
Device.
Background technology
Generator Stator Cooling water installations are the important components of generator system, the stability and reliability of its operation
Directly affect generator whether can steadily, the operation of safety, now widely used generator cooling-water device, it is internal
Ion concentration regulation, pressure regulation.
Unit is normally run when carry out changing water in Generator Stator Cooling water, if drainage speed will cause more than moisturizing speed
Stator cooling water case water level tide, if failing to find that Generator Stator Cooling water water cut-off protection will be caused to act in time, hair
Motor trips, or generation stator cooling water is out of control, causes unit outage, and gen-set damage easily occurs.
At present, the security of water process is changed to guarantee, is then entirely changed during water, it is necessary to person on duty persistently monitors and adjusts
Whole stator cooling water water level, causes person on duty to take into account other work.
Utility model content
A kind of situation of the purpose of this utility model aiming at above-mentioned prior art, it is proposed that Generator Stator Cooling water
Water overflow mechanism is changed, solves the problems, such as that existing stator needs personnel to monitor and adjust during changing water.
The purpose of this utility model is achieved through the following technical solutions：A kind of Generator Stator Cooling water changes water and overflows
Stream device, including overflow pipe, the overflow pipe are arranged on cooling water blow-off line.
Further, air hose is installed additional at the top of the overflow pipe.
Further, the overflow pipe is U-shaped overflow pipe,
Further, 1/3 of the height of the overflow pipe higher than the minimum liquid level of stator cooling water case.
The beneficial effects of the utility model are：
1st, device is simple, and technological transformation is simple, it is not necessary to change water tank internal structure, practical reliable using law of connected vessels；
2nd, compared to original operation, operations staff is simple to operate, mitigates operations staff's labour intensity；
3rd, it is safe, it is to avoid to cause Generator Stator Cooling water to cut off the water supply the hair of situation during stator cooling water changes water
It is raw, reach the essential safety that stator cold water changes water.
Brief description of the drawings
Fig. 1 changes water overflow mechanism structural representation for a kind of Generator Stator Cooling water of the utility model.
Description of reference numerals：1- overflow pipes, 2- cooling waters blow-off line, 3- air hoses, 4- stator cooling water casees.
Specific embodiment
Water overflow mechanism is changed to a kind of Generator Stator Cooling water of the utility model below in conjunction with the accompanying drawings to be described further：
The embodiment is merely to illustrate the utility model rather than limits scope of the present utility model, and those skilled in the art are to this reality
The application appended claims limited range is fallen within the modification of the new various equivalent form of values.
As shown in figure 1, a kind of Generator Stator Cooling water described in the utility model changes water overflow mechanism, including overflow pipe
1, the overflow pipe 1 is arranged on cooling water blow-off line 2, and cooling water blow-off line 2 is connected with stator cooling water case 4.
The top of the overflow pipe 1 installs air hose 3 additional.
The overflow pipe 1 is U-shaped overflow pipe,
1/3 of the height of the overflow pipe 1 higher than the minimum liquid level of stator cooling water case 4.
The utility model utilizes law of connected vessels, and installing stator cooling water additional in stator cooling water blow-off line 2 changes water overflow
Device, the height of overflow pipe 1 is higher than the 1/3 of the minimum liquid level of stator cooling water case 4.
In order to prevent blow-off line 2 from forming siphonage, cause the water level of stator cooling water case 4 low, add at the top of overflow pipe 1
Dress air hose 3.
When carrying out Generator Stator Cooling water in unit operation and changing water, water supplementing method is constant, and U-shaped overflow pipe is opened during draining
1 drainage door, adjustment moisturizing door makes the stable level of stator cooling water case 4, such water level of stator cooling water case 4 be always maintained at
Height as U-shaped overflow pipe 1, water level is not in the low phenomenon of water level.
By installing U-shaped overflow pipe 1 additional before the drainage door of stator cooling water case 4, elimination changes water process in stator cooling water
In the occurrence of cause Generator Stator Cooling water to cut off the water supply, reach the essential safety that generator unit stator cold water changes water process.
