Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
A control installation for at least two hydraulic turbines, wherein each turbine is controlled by an independent network or simultaneously by a communal network, comprising a regulator for controlling each turbine individually responsive to operational changes of the turbine with which it is associated, and a communal regulator separate from and of the same type as said first named regulator for controlling the turbines simultaneously, and switching means for the regulators, said switching means having a first position in which the communal regulator controls the turbines and a second position in which the communal regulator is disconnected from the controls of the turbines and each turbine is separately controlled by its respective individual regulator.
Claim 2
Dependent Claim
114 words
A control installation for at least two hydraulic turbines, wherein each turbine is controlled by an independent network or simultaneously by a communal network, comprising a regulator for controlling each turbine individually responsive to operational changes of the turbine with which it is associated, and a communal regulator separate from and of the same type as said first named regulator for controlling the turbines simultaneously, and switching means for the regulators, said switching means having a first position in which the communal regulator controls the turbines and a second position in which the communal regulator is disconnected from the controls of the turbines and each turbine is separately controlled by its respective individual regulator.
Claim 3
Dependent Claim
56 words
An installation according to claim 1, in which the said switching means comprises respective relays each connected to an electro-hydraulic apparatus, each relay having two positions, one position providing connection of the regulator with the associated electrohydraulic apparatus, and the other position providing connection of the communal regulator to the electro-hydraulic apparatus for the simultaneous control.
Claim 4
Dependent Claim
24 words
An installation according to claim 1, including monitoring means connected to the communal regulator for delivering a signal in the case of a misadjustment.
Claim 5
Dependent Claim
58 words
An installation according to claims 1, wherein each regulator is provided with a control device and each regulator associated with a turbine is provided with a follower device coupled to the switching means, in such a manner that the control devices for the individual regulators, respectively associated with a turbine, follow the control device of the communal regulator.
Claim 6
Dependent Claim
19 words
An installation according to claim 1, including monitoring means connected to each individual regulator and to the communal regulator.
