This automaton also includes switch state detector, for high pressure divides/closes a floodgate the on off state performing device detect, and the switch state signal detected is exported the on off state judge module to controller.
Controller and high pressure divide/close a floodgate execution device to be placed in same control chamber a, solve the problem that in this series products original, driving is high with the fault rate that actuator, feedback signal line length cause, after also solving circuit breaking, short circuit, cause switch malfunction and the drawback of tripping.
Output computation device and low-tension current/power detection device are placed in same control chamber b, solve power calculation and electric current in this series products original, power detection element line line long, such as broken string, make electric current, power calculation circuit be mistaken for no current, power, make the drawback of the security incident of high-voltage switch gear wrong diagnosis.
Control chamber a, control chamber b use the most general MODBUS 485 agreement to carry out digital communication, and physical connection can use twisted-pair shielded wire to carry out distance connection.Communication uses asynchronous serial, half-duplex transmission mode.Controller sends data in real time, and output computation device uploads the data after calculating according to the data demand sent, and controller carries out data correctness verification according to the data of the data received Yu transmission, and verification correctly takes out electric current, the magnitude of power calculated afterwards.Compared calculating by the controller central processing unit electric current to taking out, magnitude of power with internal setting value, according to result of calculation, actuator sent corresponding instruction.
Although not shown in figure, low pressure and low power/current sensing means also includes A/D analog to digital conversion circuit, for the analogue signal that low-tension current detection part and low voltage voltage detection part obtain is converted to digital signal, then the digital signal after conversion is sent to output computation device.
External 232 interfaces reserved by controller can realize remotely controlling, and detecting in real time by increasing DTU module the operational factor of transformator, detects the superpressure of transformator, overload, phase-deficient operation, real-time disengagement failure transformator, the safe operation of protection electrical network
Operation principle of the present utility model is as follows:
The analogue signal three-phase current of transformator, voltage are detected by low pressure and low power/current sensing means by low-tension current detection part and low voltage voltage detection part and the analogue signal A/D analog-to-digital conversion circuit that detection obtained is converted into digital signal, and send to output computation device the digital signal after conversion to calculate power and current value, and result of calculation is connected to by 485 interfaces the central processing unit of controller.
When during central processing unit judges three-phase, current value respectively less than setting value and performance number start timing when being less than setting value, when timing duration is equal to the delay duration (0--99 hour 59 points and 59 seconds) set, driving module is divided/closed a floodgate to central processing unit output cut-off signals to low pressure, low pressure divides/closes a floodgate driving module output drive signal to low pressure to divide/close a floodgate execution device, disconnect low-side switch, the most again after the delay duration (1-100 second) set, central processing unit output cut-off signals to high pressure divides/closes a floodgate driving module, high pressure divides/closes a floodgate driving module output drive signal to high pressure to divide/close a floodgate execution device, disconnect high side switch.Divide/close a floodgate execution device and high pressure to divide/close a floodgate the current switch states performing device to detect low pressure by switch state detector, and just detect the signal transmission obtained on off state judge module, and will determine that result is sent to central processing unit, if performing the on off state not up to expectation of device, central authorities process continue to corresponding point/closing a floodgate drives module output drive signal, with ensure low, accurate deciliter of high side switch.
When high side switch is in separating brake, if current time reaches the closing time (can set arbitrary day weekly any time) set, central processing unit output drive signal to high pressure divides/closes a floodgate driving module, divide/close a floodgate execution device that high side switch is closed a floodgate by high pressure, when time delay is to setting value (1-100 second), driving module is divided/closed a floodgate to central processing unit output drive signal to low pressure, divide/close a floodgate execution device to connect low-side switch by low pressure, recover low-pressure side and power.
When central authorities process to the corresponding driving signal duration dividing/close a floodgate driving module output, when within the time of setting, (such as 1-9.9 second) cannot detect switch state signal, central authorities process and stop driving module output drive signal to ensure to control the safety of actuator to corresponding dividing/close a floodgate.
When transformator is in off-position, when having peasant household need to be used in electricity consumption before the power-on time not up to set, can reach in advance to set the electricity consumption time with four passwords of remote controller, make transformator resume operation.
In order to ensure high-voltage switch gear not bringing onto load disjunction, communicated by RS485 with fixed frequency (10 times the most per second) between central processing unit with output computation device and carry out data exchange, this control device also has instruction device, RS485 for being carried out between indication low-voltage power/current detection device and central processing unit communicates the most normal, if RS485 communication abnormality, occur that central processing unit cannot normally read, send data, then central processing unit can export a high level by drive circuit, through resistance constant current, blood pressure lowering drives instruction device (the redness highlighted LED diode of such as 3MM) to carry out abnormal instruction, indicated horsepower, current detection signal breaks.When communication abnormality, the load of transformator cannot be made accurately judgement by central processing unit, and tripping operation delay time is accumulative can be suspended, and high-voltage switch gear does not do separating brake work, prevents bringing onto load cutoff high.
