Abstract
The utility model relates to the double-power supply switching device being applicable to Hydropower Project, is made up of the first power supply monitoring module, second source monitoring modular, the first motor-operating mechanism, the second motor-operating mechanism, the 3rd motor-operating mechanism, Programmable Logic Controller LOGO and the first load and the second load; Be control core with small-sized programmable sequence controller, be executive component with motor-operating mechanism, take Power Monitoring Unit as the double-power supply switching device that testing element is formed, instead of existing matured product, improve the portability of device, reliability, the flexibility of control and the cost performance of system, there is multiple duplicate supply switching mode, fully meet the demand of Automation of Hydropower Station system to Dual-power device.
Description
Technical field
The utility model relates to a kind of double-power supply switching device being applicable to Hydropower Project.
Background technology
Automation of Hydropower Station control system often will use double-power supply switching device, be used for providing the working power of safety and stability to control system, double-power supply switching device has the product of a lot of existing maturation, but its installation is loaded down with trivial details, and because duplicate supply switching time is unadjustable or regulating time is limited, the electrical source exchange between higher level with subordinate is caused appropriately not coordinate, versatility is low, be difficult to the application requirement meeting hydroelectric station, and cost compare is high, major part function is left unused, the non-constant of cost performance, therefore a kind of double-power supply switching device being applicable to Hydropower Project is developed extremely urgent.
Summary of the invention
The utility model provides one and meets power plant safety, stability requirement, the double-power supply switching device being applicable to Hydropower Project of complete function, convenient operating maintenance.
The utility model is achieved through the following technical solutions:
Be applicable to a double-power supply switching device for Hydropower Project, be made up of the first power supply monitoring module (1) and second source monitoring modular (2), the first motor-operating mechanism (3), the second motor-operating mechanism (4), the 3rd motor-operating mechanism (6), Programmable Logic Controller LOGO (5) and the first load (7) and the second load (8); Programmable Logic Controller LOGO (5), by being connected with the first power supply monitoring module (1), second source monitoring modular (2), gathers the supply condition of two-way power supply; Programmable Logic Controller LOGO (5) is by being connected with the nodes of locations that the first motor-operating mechanism (3), the second motor-operating mechanism (4), the 3rd motor-operating mechanism (6) provide, gather the position signalling of three motor-operating mechanisms, and by judging that the location status of two-way power supply status and three motor-operating mechanisms exports corresponding executive signal to motor-operating mechanism, ensure that the first load (7) and the second load (8) power supply reliably supply.
Operation principle of the present utility model is: under all normal state of two-way input power, respectively by the first motor-operating mechanism (3) and the second motor-operating mechanism (4), the first load (7) and the second load (8) are powered, if first via power failure, then the first load (7) and the second load (8) are powered by the 3rd motor-operating mechanism (6) and the first motor-operating mechanism (4) simultaneously; If the second road power failure, then the first load (7) and the second load (8) are powered by the 3rd motor-operating mechanism (6) and the second motor-operating mechanism (3) simultaneously.
The utility model has the advantage of
1, double-power supply switching device is convenient for installation and maintenance, simple to operate, cost performance is high.
2, the versatility of double-power supply switching device and portable strong.
3, double-power supply switching device has high reliability.
Accompanying drawing explanation
Fig. 1 is system construction drawing of the present utility model.
Embodiment
As shown in Figure 1, be applicable to a double-power supply switching device for Hydropower Project, be made up of the first power supply monitoring module 1 and second source monitoring modular 2, first motor-operating mechanism 3, second motor-operating mechanism 4, the 3rd motor-operating mechanism 6, control core 5 and the first load 7 and the second load 8.
Be implemented as follows: monitored by the state of the first power supply monitoring module 1 and second source monitoring modular 2 pairs of two-way input powers, comprise: phase sequence, phase shortage, imbalance etc. state parameter mutually, these correlation behaviors are input to Programmable Logic Controller 5, simultaneously location status information is input to Programmable Logic Controller 5 by the first motor-operating mechanism 3 and the second motor-operating mechanism 4 and the 3rd motor-operating mechanism 6, the state information of Programmable Logic Controller 5 pairs of two-way power supplys and the location status information of 3 motor-operating mechanisms carry out comprehensive analysis processing, make and clearly judging, and export control command and go to perform corresponding action to the first motor-operating mechanism 3 and the second motor-operating mechanism 4 and the 3rd motor-operating mechanism 6, realize the switching controls of duplicate supply.
