Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, the utility model provides a kind of user demarcation on-off controller, comprising: processor module, and gathers switch primary side output institute and connect bus current, the current sensor of voltage, PT transformer (being AB phase PT transformer in Fig. 1); Described current sensor is connected with processor module by current regulating circuit; Described PT transformer is connected with processor module by voltage modulate circuit; The output of described processor module is also connected with permanent magnetic drive circuit, and gathers interlock switch position signalling and energy storage signal from switch secondary side; Described user demarcation on-off controller also comprises the magneto control module be connected with processor module control output end, and is connected with the magneto of switch secondary side by this magneto control module.
It is energy storage that described magneto is used for its effect, and therefore, this magneto also can be called energy storage motor, and magneto is specially permanent magnet DC motor.
Wherein, the structural similarity of circuit modulate circuit and voltage modulate circuit, namely comprises: rectification circuit, amplifying circuit.Described processor module comprises two AD interfaces, and circuit modulate circuit is connected with processor module by corresponding A/D interface with voltage modulate circuit.
Described processor module such as and be not limited to the STC series monolithic adopting band AD functional module, ARM chip.
Described interlock switch position signalling and energy storage signal are obtained by energy storage and interlock switch position signalling sampling module, and send to processor module.
Described processor module is suitable for judging bus current state according to detected voltage, electric current, to export the corresponding control signal to switch secondary side, i.e. control switch secondary side preacceleration, reclosing and rear acceleration etc., transient fault (by the eliminating realizing transient fault that overlaps) can be removed by Intelligent drainage, permanent fault branch can be cut off again, to ensure the normal power supply of whole piece circuit.
Described user demarcation on-off controller also comprises: the PT transformer for subsequent use (being BC phase transformer in Fig. 1) be connected with bus, described PT transformer is connected with voltage modulate circuit by diverter switch with PT transformer for subsequent use, and this diverter switch is controlled by described processor module; The power taking end of the power module in described user demarcation on-off controller connects the output of diverter switch.
This user demarcation on-off controller Main Function is the normal power supply ensureing circuit, be unlikely to allow whole piece circuit play pendulum because of the fault in a branch, therefore, user demarcation on-off controller has higher reliability, especially power module, if power supply carries out action due to fault, when there is no backup battery, appearance is played pendulum due to power supply shakiness, so this user demarcation on-off controller have employed the pattern that two PT powers, the PT transformer being positioned at AB phase is main power supply PT, the PT transformer of BC phase is PT transformer for subsequent use, because the voltage of AB phase exists phase difference with the voltage of BC phase, can not be directly simple in parallel to this user demarcation power switch control, this just requires commutation circuit and switches between two-way PT, to ensure the safety of the reliable and circuit of powering, processor module is sampled to busbar voltage by PT instrument transformer, pass through rectification circuit again, amplifying circuit processes signal, the signal processed is sent into the A/D interface (AD interface) of processor module, to realize the control of described processor module to commutation circuit, realize intelligence, seamless, reliable switching, to ensure the normal work of this user demarcation on-off controller.Due to commutation circuit output is AC220V, can not directly supply whole system as operating voltage, have to pass through power module, this power module is such as but not limited to employing multi-stage switching power supply, both reduce the volume of whole controller, achieved indoor installation, additionally reduce the caloric value of whole system, energy savings, control pyrotoxin, ensure whole system reliability under the high temperature conditions.After multi-stage switching power supply continues transformation, export the reliable and stable direct-current power supply each several part of the different magnitude of voltage of many groups as operating voltage, described power module can also be powered for magneto.
