In the present embodiment, teleoperated manner is to use PLC centralized Control, and the feature of mode of operation is safely, flexibly, conveniently.Teleoperated manner is as follows: 1) user is first according to native system operating instruction, corresponding voltage is cashier's office in a shop selected in centralized Control, click on the corresponding chopper of the corresponding button adhesive under this electric pressure the most step by step, under PLC control, being ready for low pressure, middle pressure, the interlocking of high-tension switch cabinet, after a certain electric pressure is selected, the switch cubicle of other electric pressures is locked cannot adhesive, user is if any the situation of maloperation, and system also can be refused automatically.2) in centralized Control cashier's office in a shop by voltage-regulation button and digital display voltmeter, lifting trim voltage is to reach required output voltage, and user can carry out next step operation output voltage and start cabinet to user when the conditions are met.3) use complete after, user can use the power supply of whole system all to cut off by closing chopper, uses the voltage of this grade also to need again by operating procedure 1 even if rethinking), 2) power transmission again.
Local operation mode is the emergency mode used when remotely operation is broken down, and operates in switch cabinet body, and the feature of this mode is safe and reliable.Each switch cubicle is provided with on the spot/remote conversion button, makes local operation and remotely operates and will not conflict.
In the present embodiment, operational subsystems includes centralized Control cabinet, the circuit diagram of this centralized Control cabinet is as shown in Figure 2, the voltage of 220V passes through chopper 1QF1,220V is had to be converted to 110V voltage after chopper 1QF2 for wave filter by the transformation of transformator T1, PLC, frequency meter and voltage display table provide power supply.110V voltage enters the filtering of wave filter provides the DC voltage of 24V through continuous-current plant for touch screen again.
High voltage load cabinet is equipped with voltage transformer and the voltage of 380V is converted to the voltage signal of 100V, and inlet wire frequency meter gathers 0～100V voltage signal, demonstrates the frequency of end of incoming cables on dial plate.3 voltmeters (range 12000V) are added at high voltage load cabinet, AB, BC, CA are alternate, adding a 4-20mA transmitter, voltage display table i.e. can be shown that primary voltage, now voltage signal is converted into the analogue signal of PLC simultaneously and is input to the input module of PLC.
When the voltage of different grades exports, voltage display table the most all can show, when PLC receives the analog quantity inputted simultaneously, PLC is through processing, and coupled touch screen can demonstrate electric pressure now accordingly.
In the present embodiment, control subsystem and mainly include PLC module, PLC includes CPU216 (I0.0-I2.7Q0.0-Q1.7) altogether, EM221CN (I3.0-14.7), 3 digital quantity input modules of EM221CN (15.0-I6.7) EM221CN (18.0-I8.7), digital quantity input of EM223CN (I7.0-I7.7/Q2.0-Q2.7), output mixing module, digital quantity output module of EM221CN (Q3.0-Q3.7), 2 Analog input mModule of EM231CN (AI0-AI3) EM231CN (AI4-AI7).
CPU216 input signal is the switching signal of button SB1-SB24, EM221-2 (I5.0-I6.7) 16 numeral input and EM223,221-3, mainly high-voltage board 7, low-voltage cabinet chopper 1,2, load cabinet 1, low-voltage cabinet 2 separating brake, closing position signal, the boosting of oil immersion pressure regulator and blood pressure lowering, dry change 1,2 high temperature alarm tripping operation, low-voltage cabinet 1-1 fault trip is reported to the police, and low-voltage cabinet 1-1 fault trip is reported to the police.
M231-1, EM231-2 analog input, is from each switch board primary voltage and inlet wire current, by the input signal of the 4-20mA of display instrument to collect.
EM2228 point digital output, the mainly output of the relay coil of the separating brake action of load cabinet 1.
In the present embodiment, long-range operation is all realized by PLC centralized Control, controls requirement according to system and PLC control circuit arranges design control procedure.Control, interlocked control, analog quantity is the most just protected to change these several sections of programs and be analyzed.
Chopper on circuit should have a following defencive function: short-circuit protection, overload protection, open-phase protection.Additionally integrated console has emergency stop push button, in case of emergency presses emergency stop push button, and whole system major loop disconnects immediately, and with the protection person in an emergency situation and the safety of equipment, its PLC program is as shown in Figure 3.
When a certain voltage gradation exports, remaining electric pressure locks without exception, it is impossible to operation, to ensure correctness and the uniqueness of output voltage grade；Every high-tension switch cabinet, when case cabinet body door is opened, this cabinet should power-off immediately；Reciprocal interlocking between every kind of mode of operation, makes various operating system in use not interfere with each other.Its PLC program is as shown in Figure 4.
After PLC accepts analog quantity, through processing, it is achieved A/D changes, and touch screen can show magnitude of voltage, be analyzed as a example by high-voltage board 5 primary voltage, and its program is as shown in Figure 5.
In Siemens, integer data can not be converted directly to floating number, it is therefore necessary to changes through following steps.First high-voltage board 5 primary voltage data are stored in VD8 with DINT data type, then in order to promote computational accuracy, use DI_R that the data in VD8 are converted into floating number,
Relative to 0～the signal of 20mA, the collection data of siemens PLC are 0～32000, and i.e. often corresponding for mA data are 1600, and the signal 4～20mA therefore gathered relative to native system, the collection data of siemens PLC are exactly 6400～32000.Therefore 4～20mA corresponding input ranges are 32000-6400=25600, so input value needs just can obtain its percentage ratio taking gamut divided by (DIV_R) 25600,
Siemens 200 is to be moved the signals collecting carrying out 4～20mA by coordinate, the original corresponding collection signal of Siemens 200 is 0～20mA, so 4mA is occupied in the range of 4/16=0.25, namely the range ability occupied by 4～20mA is 0.25～1, and therefore input value-0.25 to complete the movement of coordinate.It is multiplied by (MUL_R) 10000 after VD20-0.25 again, just obtains the magnitude of voltage between 0-10000.
As can be seen here, the voltage data that the data between 6400-32000 corresponding for the analog signals of input are converted between 0-10000 by PLC program by linear transformation exports, and touch screen will show corresponding voltage.
The respective embodiments described above are to realize specific embodiment of the utility model, it will be understood by those skilled in the art that and in actual applications, can to it, various changes can be made in the form and details, without departing from spirit and scope of the present utility model.
