Abstract
The utility model discloses the safety control that generator jumped by a kind of turbine emergency protector connection, comprise the generator being controlled unlatching by generator comprehensive protector or closed, the steam turbine be connected with generator coaxle, and the steam line to be connected with steam turbine, steam line is provided with the main inlet throttle-stop valve fast valve that can open or close steam line, the emergency overspeed governor controlling steam turbine controls main inlet throttle-stop valve fast valve by oil path control system and opens or closes steam line, main inlet throttle-stop valve fast valve arranges the sensor detecting main inlet throttle-stop valve fast valve on off state, sensor is connected with generator comprehensive protector.The advantage of steam turbine and generator can be closed when the utility model has pressing emergency overspeed governor simultaneously.
Description
Technical field
The utility model relates to the safety control that generator jumped by a kind of turbine emergency protector connection.
Background technique
Carry out in the electric power plant generated electricity at use steam turbine and generator, provide the steam line of steam to be connected with steam turbine by main inlet throttle-stop valve fast valve, steam turbine is connected with generator coaxle.When steam turbine fault, pressing emergency overspeed governor, emergency overspeed governor makes main inlet throttle-stop valve fast valve steam off pipeline by oil path control system, steam line is stopped to steam turbine steam supply, and then steam turbine is quit work, but emergency overspeed governor can not join stop jumping while being stopped by steam turbine stops generator; When steam turbine stop and generator simultaneously join stop jumping stop time, reverse-power in the generator can be caused protect, the time grown can cause electric substation to power station power supply line jumping electrification, the production safety for electric power plant has buried major hidden danger.
Model utility content
The purpose of this utility model is to provide the safety control that generator jumped by a kind of a kind of turbine emergency protector connection simultaneously closing steam turbine and generator when pressing emergency overspeed governor.
For achieving the above object, the utility model have employed following technological scheme: the safety control of generator jumped by described a kind of turbine emergency protector connection, comprise the generator being controlled unlatching by generator comprehensive protector or closed, the steam turbine be connected with generator coaxle, and the steam line to be connected with steam turbine, steam line is provided with the main inlet throttle-stop valve fast valve that can open or close steam line, the emergency overspeed governor controlling steam turbine controls main inlet throttle-stop valve fast valve by oil path control system and opens or closes steam line, main inlet throttle-stop valve fast valve arranges the sensor detecting main inlet throttle-stop valve fast valve on off state, sensor is connected with generator comprehensive protector.
Further, the safety control of generator jumped by aforesaid a kind of turbine emergency protector connection, wherein: described sensor comprises: be installed on the block on the valve rod of main inlet throttle-stop valve fast valve, and the main inlet throttle-stop valve quick closing valve limit switch be arranged on main inlet throttle-stop valve fast valve, main inlet throttle-stop valve quick closing valve limit switch is connected with generator comprehensive protector; When main inlet throttle-stop valve fast valve steam off pipeline; block on main inlet throttle-stop valve fast valve valve rod just in time touches main inlet throttle-stop valve quick closing valve limit switch, and now the signal of main inlet throttle-stop valve fast valve steam off pipeline is sent to generator comprehensive protector by main inlet throttle-stop valve quick closing valve limit switch.
By the enforcement of technique scheme, the advantage of steam turbine and generator when the utility model has pressing emergency overspeed governor, can be closed simultaneously.
Accompanying drawing explanation
Fig. 1 is the working principle schematic diagram that the safety control of generator jumped by a kind of turbine emergency protector connection described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the safety control of generator jumped by described a kind of turbine emergency protector connection, comprise the generator 2 being controlled unlatching by generator comprehensive protector 1 or closed, the steam turbine 3 that be connected coaxial with generator 2, and the steam line 4 to be connected with steam turbine 3, steam line 4 is provided with the main inlet throttle-stop valve fast valve 5 that can open or close steam line 4, the emergency overspeed governor 6 controlling steam turbine 3 controls main inlet throttle-stop valve fast valve 5 by oil path control system 7 and opens or closes steam line 4, main inlet throttle-stop valve fast valve 5 arranges the sensor detecting main inlet throttle-stop valve fast valve on off state, sensor is connected with generator comprehensive protector 1, in the present embodiment, described sensor comprises: be installed on the block 8 on main inlet throttle-stop valve fast valve 5 valve rod, and is arranged on the main inlet throttle-stop valve quick closing valve limit switch 9 on main inlet throttle-stop valve fast valve 5, and main inlet throttle-stop valve quick closing valve limit switch 9 is connected with generator comprehensive protector 1, when main inlet throttle-stop valve fast valve 5 steam off pipeline 4, block 8 on main inlet throttle-stop valve fast valve 5 valve rod just in time touches main inlet throttle-stop valve quick closing valve limit switch 9, now the signal of main inlet throttle-stop valve fast valve 5 steam off pipeline 4 is sent to generator comprehensive protector 1 by main inlet throttle-stop valve quick closing valve limit switch 9, this sensor construction is simple, and enterprise's user cost is low,
Working principle of the present utility model is as follows: when steam turbine 3 breaks down, pressing emergency overspeed governor 6, and emergency overspeed governor 6 controls main inlet throttle-stop valve fast valve 5 steam off pipeline 4 by oil path control system 7, and after steam line 4 is closed, steam turbine 3 quits work; When main inlet throttle-stop valve fast valve 5 steam off pipeline 4; block 8 on main inlet throttle-stop valve fast valve 1 valve rod just in time touches main inlet throttle-stop valve quick closing valve limit switch 9; the signal of main inlet throttle-stop valve fast valve steam off pipeline is sent to generator comprehensive protector 1 by main inlet throttle-stop valve quick closing valve limit switch 9; after generator comprehensive protector 1 receives the signal of main inlet throttle-stop valve fast valve 5 steam off pipeline 4; can send excitation connection to generator 2 and jump signal, generator 2 receives after signal jumped by this excitation connection and quits work.The advantage of steam turbine and generator can be closed when the utility model has pressing emergency overspeed governor simultaneously.
Claims (2)
1. the safety control of a turbine emergency protector connection jumping generator, comprise the generator being controlled unlatching by generator comprehensive protector or closed, the steam turbine be connected with generator coaxle, and the steam line to be connected with steam turbine, steam line is provided with the main inlet throttle-stop valve fast valve that can open or close steam line, the emergency overspeed governor controlling steam turbine controls main inlet throttle-stop valve fast valve by oil path control system and opens or closes steam line, it is characterized in that: the sensor arranging to detect main inlet throttle-stop valve fast valve on off state on main inlet throttle-stop valve fast valve, sensor is connected with generator comprehensive protector.
