Description
Technical field
The utility model relates to turbine-generator units, is specifically related to a kind of hydropower generator air cooler leakage inspector.
Background technology
Power station is the integration engineering facility that water can be converted to electric energy, also known as hydroelectric power plant.It comprises for utilizing water to produce electric energy and the various equipment for hydroelectric station of a series of structure of hydropower station built and installing.These buildingss are utilized to concentrate the drop of natural current to form head, collect, regulate the flow of natural current, and it is transferred to the hydraulic turbine, through the co-operation of the hydraulic turbine and generator, concentrated water can be converted to electric energy, then through transformer, switchyard and transmission line of electricity etc., electric energy be inputted electrical network.What in power station, a lot of Cooling Method of Large Capacity Hydrogenerator adopted is the cooling of airtight self-circulation air, and is provided with cooling water pipe in air cooler.When a certain air cooler leaks, if find not in time, easily cause fixed subcoil insulating to destroy, ground connection or phase fault occur, jeopardizes gen-set safety.CN203100984U discloses a kind of air cooler of generator leakage inspector, its: the endless tube comprising water receiving tank, collecting container, connection collecting container and water receiving tank, being provided with the draining valve for getting rid of liquid in collecting container bottom described collecting container, in described collecting container, being provided with the sensor of the height of liquid level in detected set water receptacle.When breaking appears in air cooler copper pipe, water leakage can sharply increase, and the ponding in container can not be discharged in time, and after ponding rises to certain altitude, sensor detects that ponding is reported to the police, and signal delivers to supervisory system.Although it can detect that air cooler leaks, cannot drain the water away in time, directly jeopardize power station plant safety.
In view of this, need to invent a kind of hydropower generator air cooler leakage inspector that not only can detect water leakage situation but also ponding can be derived.
Utility model content
The purpose of this utility model is the defect overcoming prior art, provides a kind of hydropower generator air cooler leakage inspector that not only can detect water leakage situation but also can discharge ponding in time.
To achieve these goals, the technical scheme taked of the utility model is as follows:
A kind of hydropower generator air cooler leakage inspector, it comprises water receiving tank, the water accumulation pipe be communicated with water receiving tank, be arranged at the valve of described water accumulation pipe lower end, and the drainpipe to be connected with valve, described water accumulation pipe sidepiece is provided with the other pipe of ponding, and the other pipe upper end of described ponding is communicated with run-down pipe, the other end of described run-down pipe communicates with drainpipe, and the other inside pipe wall of described ponding is provided with level sensor.
Further improve as the utility model, described water receiving tank is many, is connected respectively by pipeline with water accumulation pipe.
Further improve as the utility model, the least significant end of the other pipe of described ponding is higher than the horizontal line at valve place.
Compared with prior art, the beneficial effect acquired by the utility model is as follows:
The utility model can have prompting air cooler accurately and timely to leak, and can leak in very first time discharge, ensures unit safety operation, handled easily personnel on-call maintenance.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In the accompanying drawings: 1 water receiving tank, 2 water accumulation pipes, 3 valves, 4 drainpipes, the other pipe of 5 ponding, 6 run-down pipes, 7 level sensors.
Embodiment
Detailed further describing is carried out below in conjunction with accompanying drawing 1 pair of the utility model.
As shown in Figure 1, a kind of hydropower generator air cooler leakage inspector, it comprise be arranged on air cooler of generator bottom many water receiving tank 1(figure shown in 1), the water accumulation pipe 2 be communicated with water receiving tank 1 bottom, be arranged at the valve 3 of described water accumulation pipe 2 lower end, and the drainpipe 4 to be connected with valve 3, described water accumulation pipe 2 sidepiece is provided with the other pipe 5 of ponding, the least significant end of the other pipe 5 of described ponding is higher than the horizontal line at valve 3 place, the most significant end of the other pipe 5 of ponding is not higher than the most significant end of water accumulation pipe 2, other pipe 5 upper end of described ponding is communicated with run-down pipe 6, the other end of described run-down pipe 6 communicates with drainpipe 4, other pipe 5 inwall of described ponding is provided with level sensor 7.
When generator normally runs, a small amount of condensate water that air cooler exists, is leaked and to be flowed in described water accumulation pipe 2 by pipeline through water receiving tank 1, and by the aperture of control valve, makes the Inlet and outlet water in water accumulation pipe 2 reach balance, now not ponding in the other pipe 5 of ponding.When air cooler generation leakage accident, valve 3 has little time to derive the ponding in water accumulation pipe 2, and ponding can enter in the other pipe 5 of ponding, and water level rises, and flows out, enter in drainpipe 4 after the other pipe 5 of ponding is full in run-down pipe 6.When ponding crosses level sensor 7, sensor detects that ponding is reported to the police, and signal delivers to monitoring central authorities, reminds operating personnel to there is leakage accident.
The above embodiment is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the utility model.For persons skilled in the art, to any apparent change done by it under the prerequisite not deviating from the utility model principle and spirit, all should be contemplated as falling with within claims of the present utility model.
