Technical field
The utility model relates to the power system device technology, is specifically related to a kind of storage capacitor constant current mode charging high-voltage switch controller.
Background technology
High-voltage switch gear roughly is divided into two kinds by structure at present, and a kind of is pull operation mechanism, and a kind of is permanent magnet mechanism.The pull operation mechanism characteristics: the manufacturing process complexity, the cost height, product reliability is difficult for guaranteeing the technology comparative maturity.The permanent magnet mechanism characteristics are just opposite with pull operation mechanism.We can say that future trend is permanent magnet mechanism.Realize the action of permanent magnetism high-voltage switch gear, must will charge to storage capacitor, charging modes may be crossed 2 modes and realizes in the past: 1, constant voltage charging method, its shortcoming are the breaking-ups that electric capacity itself is caused slow hot type, reduce electric capacity serviceable life, the serious electric capacity that causes burns; 2, utilize resistance or inductance to form RC or lc circuit, it is added on restriction to charging current, thereby improves electric capacity serviceable life indirectly, but still is nonlinear for capacitive process, for charging bad control of quality duration of charging, thereby cause bad control of duration of charging.
Summary of the invention
At the problems referred to above, the utility model provides a kind of effective protection storage capacitor not burnt, and improves the performance of storage capacitor and the high-voltage switch controller in life-span.
The utility model is that the technical scheme that its technical matters of solution is adopted is:
Storage capacitor constant current mode charging high-voltage switch controller comprises: main control unit; Be used to control the permanent magnetism coil of the divide-shut brake actuating of relay; Be used for storage capacitor to the permanent magnetism coil power supply; The divide-shut brake control circuit, the output terminal of storage capacitor is connected with the permanent magnetism coil by the divide-shut brake control circuit; The constant-current charge module, the feeder ear of constant-current charge module is connected with main control unit with control end, and output terminal is connected with storage capacitor.
Preferably, high-voltage switch controller comprises the testing circuit that is used to detect the storage capacitor electric weight, and the output terminal of testing circuit is connected with main control unit or constant-current charge module.
The beneficial effects of the utility model are: the utility model is provided with one can be by the constant-current charge module of main control unit control, make storage capacitor can carry out the constant current mode charging, charging process is directly controlled, and the reliability of the access times of storage capacitor and life-span and the whole power supply of high-voltage switch gear control product is improved.
Description of drawings
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is that system of the present utility model forms synoptic diagram.
Embodiment
With reference to Fig. 1, high-voltage switch controller of the present utility model, comprise main control unit 1, permanent magnetism coil 2, storage capacitor 3, divide-shut brake control circuit 4, constant-current charge module 5, can further include testing circuit 6, be used to detect the electric weight of storage capacitor 3, thereby make the live part of storage capacitor form closed-loop control system, guarantee that charging is more safe and reliable.
Main control unit 1 is the data processing and the control section of high-voltage switch controller, and it can utilize various compute chip to make.Permanent magnetism coil 2 is used to control the action of divide-shut brake relay, and 3 of storage capacitors are used for to 2 power supplies of permanent magnetism coil.Divide-shut brake control circuit 4 is serially connected between storage capacitor 3 and the permanent magnetism coil 2, and it generally is subjected to the control of main control unit 1.When main control unit 1 detects alternate, earth fault separating brake or closing by hand, storage capacitor 3 needs to give permanent magnetism coil 2 electric fluxs (be the divide-shut brake relay of high-voltage switch gear will move time), by divide-shut brake control circuit 4 electric flux moment of in advance having stored up at storage capacitor 3 is flowed to permanent magnetism coil 2, thereby make the high-voltage switch gear action.
Constant-current charge module 5 is used for storage capacitor 3 is charged, and it is worked under the control of main control unit 1, and the power supply energy of input is transformed into storage capacitor 3 desired constant-current charging powers, offers storage capacitor 3, for storage capacitor 3 provides electric flux.The output terminal of testing circuit 6 can be connected with main control unit 1 or constant-current charge module 5, and it can detect the state of charge of storage capacitor 3 in real time.Under the cooperation of testing circuit 6, after storage capacitor 3 is full of electric flux, constant-current charge module 5 can be turn-offed the output electric energy automatically, can not cause the waste of electric flux, in addition, after detecting storage capacitor 3 and being lower than the highest energy storage electric flux, constant-current charge module 5 conveying capacity is at once given storage capacitor 3, thereby the electric flux of bag card storage capacitor 3 is for next high-voltage switch gear action is preparation.
Embodiment of the present utility model is not restricted to the described embodiments, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
